Notes to Consolidated Financial Statements
(Unaudited)
Note 1 - Description of Business and Summary
of Significant Accounting Policies
Nature of Business -
Actinium Pharmaceuticals, Inc. (the “Company”, “Actinium”, or “We”) is a clinical-stage, biopharmaceutical
company applying its proprietary platform technology and deep understanding of radioimmunobiology to the development of novel targeted
therapies known as ARCs or Antibody Radiation-Conjugates.
Basis of Presentation
- Unaudited Interim Financial Information - The accompanying unaudited interim consolidated financial statements and related
notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.
GAAP”) for interim financial information, and in accordance with the rules and regulations of the United States Securities
and Exchange Commission (the “SEC”) with respect to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited interim
consolidated financial statements furnished reflect all adjustments (consisting of normal recurring adjustments) which are, in
the opinion of management, necessary for a fair statement of the results for the interim periods presented. Interim results are
not necessarily indicative of the results for the full year. These unaudited interim consolidated financial statements should be
read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s annual
report on Form 10-K for the year ended December 31, 2019.
Reverse Stock Split
- On April 29, 2020, the Company received a deficiency letter from the NYSE American LLC, or NYSE American, indicating that
the Company was not in compliance with the NYSE American continued listing standard set forth in Section 1003(f)(v) of the NYSE
American Company Guide because its shares of common stock had been selling for a substantial period of time at a low price per
share. Pursuant to Section 1003(f)(v) of the NYSE American Company Guide, the NYSE American staff determined that the Company’s
continued listing is predicated on the Company effecting a reverse stock split of its common stock or otherwise demonstrating sustained
price improvement within a reasonable period of time, which the staff determined to be no later than October 29, 2020.
On October 18, 2019, the
Company’s board of directors, or the Board, unanimously approved, subject to stockholder approval, an amendment to the Company’s
certificate of incorporation to effect a reverse stock split of its outstanding common stock by combining outstanding shares of
common stock into a lesser number of outstanding shares of common stock by a ratio of not more than 1-for-75 prior to December
18, 2020, with the exact ratio to be set within this range by the Board at its sole discretion. At its Annual Meeting of Stockholders
held on December 18, 2019, the Company’s stockholders approved such amendment to its certificate of incorporation.
7
On August 7, 2020, the Board unanimously approved a reverse
stock split of its outstanding common stock by combining outstanding shares of common stock into a lesser number of outstanding
shares of common stock by a ratio of 1-for-30, and on August 10, 2020, the Company filed with the Secretary of State of Delaware
a certificate of amendment to its certificate of incorporation to effect the reverse stock split. The reverse stock split became
effective as of 5:00 p.m. Eastern Time on August 10, 2020, and the Company’s common stock began trading on a split-adjusted
basis when the market opened on August 11, 2020. Accordingly, all common share and per common share data in these consolidated
financial statements and related notes hereto have been retroactively adjusted to account for the effect of this reverse stock
split for all periods presented. In addition, at the effective time of the reverse stock split, the number of shares of our common
stock reserved for issuance upon exercise of all options and warrants to acquire common stock have been proportionally decreased,
and the exercise price of all options and warrants to acquire common stock have been proportionally increased.
Principles of Consolidation
- The consolidated financial statements include the Company’s accounts and those of the Company’s wholly owned
subsidiary.
Use of Estimates in
Financial Statement Presentation - The preparation of these consolidated financial statements in conformity with U.S. GAAP
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of
the consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ
from those estimates.
Impact of COVID–19
Pandemic on Financial Statements
In December 2019, a novel
strain of COVID-19 was reported in China. Since then, COVID-19 has spread globally. The spread of COVID-19 from China to other
countries has resulted in the World Health Organization (“WHO”) declaring the outbreak of COVID-19 as a “pandemic,”
or a worldwide spread of a new disease, on March 11, 2020. Many countries around the world have imposed quarantines and restrictions
on travel and mass gatherings to slow the spread of the virus and have closed non-essential businesses, and many local jurisdictions
continue to have such restrictions in place.
As local jurisdictions
continue to put restrictions in place, the Company’s ability to continue to operate its business may also be limited. Such
events may result in a period of business, supply and drug product manufacturing disruption, and in reduced operations, any of
which could materially affect the Company’s business, financial condition and results of operations. In response to COVID-19,
the Company implemented remote working and thus far, has not experienced a significant disruption or delay in its operations as
it relates to the clinical development or drug production of our drug candidates.
The spread of COVID-19,
which has caused a broad impact globally, may materially affect the Company economically. While the ultimate economic impact brought
by, and the duration of, the COVID-19 pandemic may be difficult to assess or predict, including new information which may emerge
concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others, the pandemic has resulted
significant disruptions in the general commercial activity and the global economy and caused financial market volatility and uncertainty
in significant and unforeseen ways in the recent months. A continuation or worsening of the levels of market disruption and volatility
seen in the recent past could have an adverse effect on the Company’s ability to access capital, which could in the future
negatively affect the Company’s liquidity. In addition, a recession or market correction resulting from the spread of COVID-19
could materially affect the Company’s business and the value of the Company’s common stock.
Additionally, COVID-19
may result in delays in receiving approvals from local and foreign regulatory authorities, delays in necessary interactions
with IRB’s or Institutional Review Boards, local and foreign regulators, ethics committees and other important agencies and
contractors due to limitations in employee resources or forced furlough of government employees.
To date, COVID-19 has not
had a financial impact on the Company. However, COVID-19 has caused severe disruptions in transportation and limited access to
the Company’s facility, resulting in limited support from its staff and professional advisors.
Cash, Cash Equivalents
and Restricted Cash - The Company considers all highly liquid accounts with original maturities of three months or less to
be cash equivalents. Balances held by the Company are typically in excess of Federal Deposit Insurance Corporation insured limits.

Cash, cash equivalents and restricted cash

$ 9,693
Current restricted cash
relates to credit card accounts, while long-term restricted cash relates to a certificate of deposit held as collateral for a letter
of credit issued in connection with the Company’s lease for corporate office space.
Leases – The
Company has operating and finance leases for corporate office space, office equipment and furniture located at the corporate office
space. Leases with an initial term of 12 months or less are not recorded on the balance sheet; lease expense for these leases is
recognized on a straight-line basis over the lease term.
Fair Value of Financial
Instruments - Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability,
in an orderly transaction between market participants. A fair value hierarchy has been established for valuation inputs that gives
the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable
inputs.
Research and Development
Costs - Research and development costs are expensed as incurred. These costs include the costs of manufacturing drug product,
the costs of clinical trials, costs of employees and associated overhead, and depreciation and amortization costs related to facilities
and equipment. Research and development reimbursements are recorded by the Company as a reduction of research and development costs.
Share-Based Payments
- The Company estimates the fair value of each stock option award at the grant date by using the Black-Scholes option pricing
model. The fair value determined represents the cost for the award and is recognized over the vesting period during which an employee
is required to provide service in exchange for the award. The Company accounts for forfeitures of stock options as they occur.
Net Loss Per Common
Share - Basic loss per common share is computed by dividing the net loss available to common stockholders by the weighted
average number of common shares outstanding during the reporting period. For periods of net income, and when the effects are not
anti-dilutive, diluted earnings per share is computed by dividing net income available to common stockholders by the weighted-average
number of shares outstanding plus the impact of all potential dilutive common shares, consisting primarily of common shares underlying
common stock options and warrants using the treasury stock method. The Company issued pre-funded warrants in April 2020 and June
2020 that are considered outstanding shares for the purposes of calculating net loss per common share, see Note 4 for additional
information. Since the shares underlying the outstanding 2.3 million pre-funded warrants are issuable for negligible consideration
and are fully vested and exercisable, they are considered outstanding for the calculations of both basic and diluted loss per
share.
9
For periods of net loss,
diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares
is anti-dilutive. For the six months ended June 30, 2020 and 2019, the Company’s potentially dilutive shares, which include
outstanding common stock options and warrants have not been included in the computation of diluted net loss per share as the result
would have been anti-dilutive.

Accounting Standards
Recently Adopted
In August 2018, FASB issued
ASU 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820). The updated guidance improves the disclosure requirements
on fair value measurements, primarily associated with Level 3 fair value measurements and is effective for fiscal years, and interim
periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the standard
for disclosures modified or removed with a delay of adoption of the additional disclosures until their effective date. The Company
adopted this standard effective January 1, 2020 and the standard did not have a significant impact to the Company’s financial
statements.
In November 2018, FASB
issued ASU 2018-18, C ollaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606, which,
among other things, provides guidance on how to assess whether certain collaborative arrangement transactions should be accounted
for under Topic 606. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years,
beginning after December 15, 2019, with early adoption permitted. The Company adopted this standard effective January 1, 2020
and the standard did not have a significant impact to the Company’s financial statements.
Note 2 - Commitments and Contingencies
Agreements
The Company has entered
into agreements with third parties for the rights to certain intellectual property, manufacturing and clinical trial services under
which the Company may incur obligations to make payments including upfront payments as well as milestone and royalty payments.
Notable inclusions in this category are:
a.
Oak Ridge National Laboratory (“ORNL”) – The Company is contracted to purchase radioactive material to be used for research and development, with a renewal option at the contract end. During the six months ended June 30, 2020 and 2019, the Company purchased material from ORNL of $0.1 million in each period. In November 2019, the Company signed a contract with ORNL to purchase $0.3 million of radioactive material during calendar year 2020.
b.
On June 15, 2012, the Company entered into a license and sponsored research agreement with Fred Hutchinson Cancer Research Center (“FHCRC”) to build upon previous and ongoing clinical trials with BC8 (licensed antibody). FHCRC has completed both a Phase 1 and Phase 2 clinical trial with BC8. The Company has been granted exclusive rights to the BC8 antibody and related master cell bank developed by FHCRC. A milestone payment of $1 million will be due to FHCRC upon FDA approval of the first drug utilizing the licensed BC 8 antibody. Upon commercial sale of the drug, royalty payments of 2% of net sales will be due to FHCRC.
Collaborative Agreement
In March 2018, the
Company entered into a research and option agreement with Astellas Pharma Inc. (“Astellas”) to develop ARCs using the
Company’s AWE Technology Platform. Under this collaboration, the Company will utilize its AWE Platform to conjugate and label
selected Astellas targeting agents with an Actinium-225 payload. The Company is also responsible for conducting preclinical validation
studies on any ARCs generated. Payments from Astellas under this agreement are accounted for as a reduction to research and development
expense.
10
Note 3 - Leases
The Company adopted ASC
842 as of January 1, 2019, using a modified retrospective approach and applying the standard’s transition provisions at January
1, 2019, the effective date. The Company made an accounting policy election to exclude from balance sheet reporting those leases
with initial terms of 12 months or less.
The Company determines
if an arrangement is a lease at inception. This determination generally depends on whether the arrangement conveys to the Company
the right to control the use of a fixed asset for a period of time in exchange for consideration. Control of an underlying asset
is conveyed to the Company if the Company obtains the rights to direct the use of and to obtain substantially all of the economic
benefits from using the underlying asset. The Company has lease agreements which include lease and non-lease components, which
the Company has elected to account for as a single lease component for all classes of underlying assets. Lease expense for variable
lease components are recognized when the obligation is probable.
Right-of-use assets and
liabilities are recognized at commencement date based on the present value of lease payments over the lease term. ASC 842 requires
a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily
determined, its incremental borrowing rate. As an implicit interest rate is not readily determinable in the Company’s leases,
the incremental borrowing rate is used based on the information available at commencement date in determining the present value
of lease payments.
The lease term for all
of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by either a
Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend
(or not to terminate) the lease controlled by the lessor. Options for lease renewals have been excluded from the lease term (and
lease liability) for the majority of the Company’s leases as the reasonably certain threshold is not met.
At June 30, 2020, the Company
has an operating lease for corporate office space and two finance leases for office equipment and furniture located in the corporate
office space. In addition, the Company has auxiliary corporate office space that it rents on a month-to-month basis; this rental
is accounted for as an operating lease with the same term as the Company’s main office in the same building.

Note 4 - Equity
On August 7, 2020,
the Board unanimously approved a reverse stock split of its outstanding common stock by combining outstanding shares of common
stock into a lesser number of outstanding shares of common stock by a ratio of 1-for-30, and on August 10, 2020, the Company filed
with the Secretary of State of Delaware a certificate of amendment to its certificate of incorporation to effect the reverse stock
split. Accordingly, all common share and per common share data in these consolidated financial statements and related notes hereto
have been retroactively adjusted to account for the effect of this reverse stock split for all periods presented.
On April 24, 2020,
the Company issued and sold 4.3 million shares of common stock and 2.8 million pre-funded warrants to purchase shares of common
stock. The price to the public in this offering for each share of common stock was $4.50 and for each pre-funded warrant was $4.497.
Each pre-funded warrant has an exercise price of $0.003 per share and is exercisable immediately upon issuance. The pre-funded
warrants are subject to certain limitations on beneficial ownership. Gross proceeds from this offering to Actinium were $31.6 million,
before deducting underwriting discounts and commissions and other offering expenses payable by the Company. Net proceeds from this
offering were $29.1 million.
In June 2020, holders
of 1.2 million pre-funded April 2020 warrants exercised their warrants at $0.003 per share and received 1.2 million shares of common
stock.
12
On June 19, 2020, the
Company issued and sold 1.9 million shares of common stock and 0.7 million pre-funded warrants to purchase shares of common stock.
The price to the public in this offering for each share of common stock was $9.75 and for each pre-funded warrant was $9.747. Each
pre-funded warrant has an exercise price of $0.003 per share and is exercisable immediately upon issuance. The pre-funded warrants
are subject to certain limitations on beneficial ownership. Gross proceeds from this offering to Actinium were $25.0 million, before
deducting underwriting discounts and commissions and other offering expenses payable by the Company. Net proceeds from this offering
were $23.0 million.
In December 2018, the
Company entered into the Amended and Restated At Market Issuance Sales Agreement with B. Riley FBR, Inc. and JonesTrading Institutional
Services LLC, pursuant to which the Company conducted its at-the market program. During the six months ended June 30, 2020, the
Company sold 0.3 million common shares through its at-the-market program, resulting in net proceeds of $2.5 million.
In October 2018, the
Company and Lincoln Park Capital Fund, LLC (“Lincoln Park”) entered into a purchase agreement and a registration rights
agreement, pursuant to which the Company has the right to sell to Lincoln Park shares of the Company’s common stock having
an aggregate value of up to $32.5 million, subject to certain limitations and conditions set forth in the agreement. During the
six months ended June 30, 2020, the Company elected to sell to Lincoln Park 27 thousand shares and received $0.2 million.
In June 2020, the Company
issued 5 thousand shares of restricted common stock, valued at $30 thousand, for consulting services.
For the six months
ended June 30, 2019, holders of March 2018 series A warrants exercised 83 thousand shares, resulting in the Company receiving $1.5
million. The remaining March 2018 series A warrants expired in March 2019.
The Company has outstanding
warrants to purchase 1,907 shares of common stock that include down-round protection. For warrants with down-round protection,
a deemed dividend is recorded for the change in fair value of the warrants when the down-round provision is triggered. As result
of the April 2019 offering, the exercise price of the warrant was reset from $37.50 per share to $26.40 per share. As a result
of the April 2020 offering and June 2020 offering, the exercise price of the warrant was reset from $26.40 per share to $15.60
per share. The down-round protection provision in the above warrants created a deemed dividend to common stockholders of $1 thousand
in the six months ended June 30, 2020 and 2019, which are reflected in the accompanying consolidated statement of operations and
consolidated statement of changes in stockholders’ equity.

Description of Business
Actinium Pharmaceuticals,
Inc. is a clinical-stage, biopharmaceutical company applying its proprietary platform technology and deep understanding of radioimmunobiology
to the development of novel targeted therapies known as ARCs or Antibody Radiation-Conjugates. Radiation is an effective therapeutic
modality that is used in the treatment of over fifty percent of all cancer patients and often combined with chemotherapy and immunotherapy
for greater therapeutic effect. Radiation is typically administered from outside the body, which constrains the amount that can
be administered to patients due to dose-limiting toxicities. In addition, due to the diffuse nature of the external radiation beam,
its usage is limited to solid tumors and cannot be used in blood cancers, which are diffuse. ARCs combine the cell-killing ability
of a radioisotope payload with a targeting agent, such as a monoclonal antibody, or mAb, to deliver radiation inside the body to
specific cells, to potentially generate greater efficacy and less toxicity. ARCs usage is broader than external delivered radiation
as they can be used for both solid tumors and blood cancers. Blood or hematologic cancers are highly sensitive to radiation and
our clinical pipeline is focused on ARCs targeting the antigens CD45 and CD33, both of which are expressed in multiple hematologic
cancers. Our clinical programs are focused on two primary areas: targeted conditioning prior to a cell or gene therapy procedure
and therapeutics, either in combination with other agents or as a monotherapy. Our product development strategy is actively informed
by clinical data with our ARCs in over 500 patients, including the ongoing SIERRA trial. Our clinical pipeline has emanated from
our AWE, or Antibody Warhead Enabling technology platform, which is protected by over 120 issued and pending patents, trade secrets
and know-how and is being utilized in a collaborative research partnership with Astellas Pharma, Inc.
We are advancing the only
multi-target, multi-indication clinical-stage pipeline for targeted conditioning and the only ARC-based targeted conditioning regimens
in development. Our ARCs for targeted conditioning are intended to potentially enable improved access to cell-based therapies with
curative potential, including BMT, or bone marrow transplant, ACT, or adoptive cell therapy such as CAR-T, and Gene Therapy, as
well as improved outcomes. Conditioning in the context of BMT, ACT or Gene Therapy is the act of depleting certain blood and immune-forming
cells, including bone marrow stem cells and, in some cases, diseased cells prior to transplanting new cells into a patient. Currently,
conditioning is accomplished using a combination of chemotherapeutic agents and external radiation. These non-targeted conditioning
regimens may prevent a patient from receiving a potentially curative therapy and hinder outcomes due to their toxicities. ARCs
have the potential to increase patient access and outcomes by way of their ability to selectively deplete targeted cells while
sparing normal healthy cells. We use our ARCs at high isotope dose levels to achieve myeloablation, which fully depletes bone marrow
stem cells and at lower isotope dose levels to achieve lymphodepletion, which spares bone marrow stem cells from depletion. In
addition, dosing may be titrated downward from myeloablative doses to achieve partial myeloablation, which may be appropriate for
certain gene therapy programs.
15
CD45 Targeted Conditioning Program
Our CD45 ARC is comprised
of the anti-CD45 monoclonal antibody known as apamistamab (formerly BC8) and the radioisotope I-131 or Iodine-131. CD45 is an antigen
expressed on leukemia, lymphoma and myeloma cancer cells, as well as nucleated immune cells, but is not expressed outside of the
hematopoietic, or blood, system. This unique expression on blood cancer and immune cells enables simultaneous depletion of both
cell types, making CD45 an optimal antigen for targeted conditioning applications. CD45 is a cell surface antigen with an average
expression of 200,000 copies per cell, however, it only internalizes at a rate of 10-15%. We believe our ARC approach is the most
effective method to target CD45 positive cells, as the radioisotope payload linear energy transfer can readily ablate a targeted
cell without requiring payload internalization like an antibody drug conjugate or rely on biological effector function processes
like a naked antibody. Furthermore, since CD45 expression level varies from low to high antigen density as the immune cells become
more terminally differentiated, we can selectively condition depending on the therapeutic application, from full myeloablation
to transient lymphodepletion, by adjusting the dose or intensity of the I-131 isotope payload. Full myeloablation can be achieved
with high doses of I-131, as its energy pathlength and crossfire effect can penetrate into bone marrow niches to target and deplete
blood and immune system forming bone marrow stem cells. Myeloablation is applicable to autologous or allogeneic BMT and to autologous
gene-edited or modified therapies that can reconstitute a patient’s blood and immune systems. Alternatively, low doses of
I-131 can be transiently lymphodepleting and spare a patient’s bone marrow stem cells, which we believe is ideal for ACT
applications such as CAR-T. We intend to develop our CD45 targeted conditioning program for BMT, ACT and Gene Therapy applications
for malignant and non-malignant diseases.
Our lead CD45 targeted
conditioning product candidate is Iomab-B, which uses high doses of I-131 to achieve myeloablative conditioning prior to a BMT.
Iomab-B is currently being studied in the pivotal Phase 3 Study of Iomab-B in Elderly Relapsed or Refractory AML, or SIERRA, clinical
trial for targeted conditioning prior to an allogeneic BMT for patients with active, relapsed or refractory (r/r) Acute Myeloid
Leukemia, or AML, who are age 55 or older. Patients with active, r/r AML are not normally considered eligible for BMT and the SIERRA
trial is the only randomized Phase 3 trial to offer BMT as a treatment option for this patient population. The SIERRA trial compares
outcomes of patients randomized to receive Iomab-B and a BMT (the study arm) to those patients randomized to receive physician’s
choice of salvage chemotherapy (the control arm). Salvage chemotherapy is also defined as conventional care, as no standard of
care exists for this patient population. Patients who fail to achieve a CR or Complete Response on the control arm are ineligible
to proceed to a BMT, but the trial design permits these patients to “cross over” to receive the study arm treatment
if they meet the eligibility criteria. The primary endpoint of the SIERRA trial is durable Complete Remission, or dCR, of six months
and the secondary endpoint is one-year Overall Survival, or OS. When the crossover patients receive Iomab-B and BMT, they have
not achieved remission with their salvage therapy and are considered to be failures for the primary endpoint of the study. The
SIERRA trial is currently active at 20 sites in the United States and Canada, which includes many of the leading BMT sites based
on volume. We expect to complete enrollment of the SIERRA trial and have topline data that we believe will support the submission
of a Biologics License Application, or BLA, with the U.S. Food and Drug Administration, or FDA, in 2021. If approved, we expect
our initial commercial launch would target the leading 50-100 BMT and medical centers that perform the vast majority of BMT’s
in the United States. In the European Union or EU, we received favorable feedback from the European Medicines Agency or EMA via
their scientific advice program that the trial design, primary endpoint and planned statistical analysis from the SIERRA trial
are acceptable as the basis for a Marketing Authorization Application or MAA. Additionally, the EMA commented that it does not
anticipate the need for further standalone preclinical toxicology or safety studies. Overall, transplant procedures in the EU are
approximately fifty percent higher than in the United States with a similar market dynamic with a majority of BMT volume being
conducted in a concentrated number of leading medical centers. We intend to secure a partner for Iomab-B in the EU.
Safety and feasibility
data from the first 75 patients enrolled on the SIERRA trial, which represents 50% of the total of 150 patients to be enrolled
in the trial, was presented in an oral presentation at the Transplantation & Cellular Therapy Meetings of the American Society
for Transplantation and Cellular Therapy (ASTCT) and Center for International Bone & Marrow Transplant Research (CIBMTER) in
February 2020. It was reported that 100% of patients (31/31) on the study arm that received a therapeutic dose of Iomab-B received
a BMT, with a median time to BMT of 30 days, and all patients achieved neutrophil and platelet engraftment in a median time of
20 days despite a high median blast count of 30%. On the control arm, only 18% of patients (7/38) achieved remission after salvage
therapy, and then received a BMT with a median time to BMT of 67 days and median blast count of 26%. Of the 82% of patients failing
to achieve a CR with conventional care (31/38), 20 patients were eligible to cross over to the study arm. These patients are considered
as having failed the primary endpoint of the study. All crossover patients who received the therapeutic dose of Iomab-B (20/20)
received a BMT, with a median time to BMT of 64 days and all patients achieved engraftment in a median time of 19 days despite
high median blast count of 35% at time of crossover. It was also reported that 100-day non-relapse transplant-related mortality
(100-day TRM) of the study or Iomab-B arm was 6% (2/31) of patients that received a BMT compared to 29% of patients (2/7) who received
a BMT after salvage therapy on the control arm. The universal engraftment rate and low 100-day TRM rate of the Iomab-B arm resulted
in 29 patients potentially evaluable for the primary endpoint compared to 5 patients in the control arm, a nearly six times difference.
16
The SIERRA trial is
powered for up to two interim analyses of the primary endpoint of dCR of 180 days exercisable at our discretion and triggered by
an enrollment range of 70 to 110 patients. We exercised a single ad-hoc analysis in the second quarter of 2020, based on the data
reported from SIERRA thus far and the status of enrollment at the time of triggering our ad hoc analysis. The ad hoc analysis is
expected to be completed by the end of 2020, which could generate topline data for the primary endpoint and early termination of
the trial if positive. Based on the statistical plan of the study, a single ad-hoc analysis would result in a minimal alpha spend
of no more than 0.00925, depending on the number of patients included in the ad-hoc analysis.
Our Iomab-ACT program is
intended for targeted conditioning prior to ACT or Gene Therapy and uses the same 131 I-apamistamab ARC construct as
Iomab-B at varying doses. At lower doses of one-eighth to one-sixth of the myeloablative dose, it is applicable for lymphodepletion
prior to CAR-T or certain Gene Therapy applications where stem cell myeloablation is not necessary. At higher doses it is applicable
for Gene Therapy applications where stem cell myeloablation is necessary.
In January 2020, we announced
a collaboration with University of California Davis to utilize Iomab-ACT conditioning in an ongoing Phase 1/2 trial with a novel
anti-HIV autologous stem cell gene therapy for patients with HIV-related lymphoma. We believe this to be the first Gene Therapy
trial to use an ARC-based conditioning regimen. 131 I-Apamistamab has clinical proof of concept as a targeted conditioning
regimen for patients with high-risk, relapsed or refractory lymphoma prior to an autologous stem cell transplant from a previous
study, where a favorable safety profile with no dose-limiting toxicities and minimal non-hematologic toxicities were observed and
promising efficacy with median overall survival not reached (range: 29 months to not reached) and 31% of patients in prolonged
remission at a median of 36 months follow up (range: 25 – 41 months). In this study, Iomab-ACT is intended to replace the
chemotherapy-based condition regimen known as BEAM (BCNU/carmustine, etoposide, cytarabine, and melphalan) to simultaneously kill
the patient’s lymphoma cells and deplete the patient’s stem cells to make room for the transplant. Upon engraftment,
the transplanted gene-modified autologous stem cells containing three anti-HIV genes are intended to equip the patient with a new
immune system that is resistant to the HIV virus. Iomab-ACT will be substituted for BEAM in the ongoing Phase 1/2 trial and we
expect to have clinical proof of concept data in 2021.
We believe our Iomab-ACT
program is highly differentiated when compared to Fludarabine and Cyclophosphamide or Flu/Cy or other chemotherapy-based regimens
that are used as the standard of practice today for lymphodepletion prior to CAR-T. CD45 is an antigen expressed on certain immune
cell types that are relevant to the mechanism of CAR-T therapies including lymphocytes, regulatory T cells and macrophages that
have been associated with clinical responses that may limit the safety, efficacy and durability of response of these CAR-T therapies
including Cytokine Release Syndrome, or CRS, and neurotoxicity. Some of these limitations may be attributable to the chemotherapy-based
conditioning agents that are being used prior to CAR-T therapies. Preclinical data supporting the rational for our Iomab-ACT program
was presented at multiple medical conferences in 2019. Unlike chemotherapy, preclinical data suggests Iomab-ACT is targeted in
nature and, due to this targeted effect, we expect we can improve CAR-T cell expansion more efficiently, potentially resulting
in responses that are more durable, but also resulting in reduced CAR-T related toxicities. Importantly, we expect the Iomab-ACT
program construct to enable lymphodepletion through a single-dose, outpatient administration versus Flu/Cy or other chemotherapy-based
lymphodepletion regimens that can require multiple infusion cycles over several days. Because of this potentially superior profile,
the Iomab-ACT construct could result in improved access to CAR-T therapy and better outcomes. We intend to begin a clinical trial
with 131 I-apamistamab as a targeted conditioning agent prior to CAR-T, subject to identifying a suitable partner and
we expect to have Phase 1 clinical proof of concept data in 2021.
17
CD33 Program: Targeted Conditioning, Combinations
and Therapeutics
Our CD33 program is evaluating
the clinical utility of an ARC comprised of the anti-CD33 mAb lintuzumab linked to the potent alpha-emitting radioisotope Actinium-225
or Ac-225. CD33 is expressed in the majority of patients with AML and myelodysplastic syndrome, or MDS, as well as approximately
one third of patients with multiple myeloma. Our CD33 development program is driven by data obtained from over one hundred treated
patients, including results from a Phase 1/2 trial that was conducted in 58 patients with newly diagnosed AML, which was completed
in 2018. This clinical data, as well as our experience with Iomab-B, is shaping a two-pronged approach with our CD33 program, where
at high doses we are exploring its use for targeted conditioning and at low doses we are exploring its use for therapeutic purposes
in combination with other modalities, such as chemotherapy, targeted agents or immunotherapy.
Actimab-MDS is our second
clinical trial focused on targeted conditioning, in this case for patients with high-risk MDS and is our second pivotal program.
Actimab-MDS is informed by prior experience with our CD33 ARC in multiple trials for patients with AML, MDS and for patients that
have progressed from MDS to AML, which is also known as secondary AML. Data from these trials showed that our CD33 ARC had single-agent
activity capable of producing complete remissions (CRs) in certain patients at varying dose levels with minimal non-hematologic
extramedullary toxicities. However, dose-dependent myelosuppression, a class effect of CD33 directed therapies, was seen in many
of these patients. Given that myelosuppression is necessary prior to a BMT and that a BMT can rescue patients with myelosuppression,
we decided to pursue a trial in targeted conditioning in high-risk MDS patients with this ARC in combination with Reduced Intensity
Conditioning, or RIC, regimens. RIC regimens are comprised of low doses of chemotherapies such as fludarabine, cytarabine, busulfan
or melphalan. A BMT is the only curative treatment option for these patients with high-risk MDS who have poor, or very poor cytogenetics.
However, these patients have poor outcomes due to high relapse rates following a BMT. Based on our interactions with FDA to date,
we will conduct a Phase 1 dose-finding clinical trial that will be followed by a randomized trial that, depending on the results
observed, may potentially serve as a pivotal trial to support the submission of a BLA. We are currently finalizing discussions
with the FDA.
We are also studying our
CD33 ARC construct at various dose levels and dosing regimens in combination with other therapeutic modalities such as chemotherapy,
targeted agents or immunotherapy in CD33 expressing hematologic disease indications. We believe that radiation can be synergistic
when used in combination with these modalities based on mechanistic rationale supported by our own clinical data, preclinical research
and scientific and clinical evidence in the literature. We have prioritized our efforts and resources in favor of combination trials
for our CD33 program development strategy rather than single agent trials, which we are no longer advancing at this time. Our CD33
ARC development program encompasses the following ongoing and planned trials:
Combination Trials :
●
Phase 1 investigator initiated Actimab-A + CLAG-M combination trial with the salvage chemotherapy regimen CLAG-M (cladribine, cytarabine, filgrastim and mitoxantrone) for patients with relapsed or refractory AML at the Medical College of Wisconsin. At the 2019 American Society of Hematology Annual Meeting, it was reported that 86% of patients (6/7) receiving 0.50 µCi/kg of Actimab-A, and CLAG-M achieved a complete remission after receiving Actimab-A + CLAG-M, which is nearly 60% greater than the 55% remission rate observed in a study of CLAG-M alone conducted at MCW in the same r/r AML patient population. In addition, 71% of these patients (5/7) achieved negative minimal residual disease status, indicating that these are deep remissions. The 0.50 µCi/kg dose of Actimab-A was shown to be subtherapeutic as a single agent. Since the combination to date has been well tolerated, the study progressed to the third and final cohort for the study of Actimab-A at a dose of 0.75 µCi/kg in March 2020 and we expect to complete this trial by the end of 2020. Upon completion, we intend to explore a regulatory pathway for a pivotal trial that could potentially support a registration. The combination of Actimab-A + CLAG-M is supported by mechanistic rationale for combining inhibitors of DNA replication and/or repair processes such as mitoxantrone, a topoisomerase-II inhibitor, and radiation, as imparted by tumor targeting of Ac-225 with Actimab-A. The Actimab-A + CLAG-M combination study has provided proof of principle that the addition of subtherapeutic doses of Actimab-A to other AML therapies can lead to well tolerated regimens with improved responses.
18
Phase 1 Actimab-A + Ven combination trial with the BCL-2 inhibitor Venetoclax (Ven) for patients with relapsed or refractory AML. This trial will be led by UCLA Medical Center and will be conducted at three additional trial sites. This combination is supported by mechanistic evidence in preclinical studies using Ven-resistant AML tumor cell lines. In these models, we have demonstrated that Actimab-A can deplete Mcl-1 and Bcl-XL, two proteins implicated in mediating resistance to venetoclax, in addition to causing potentially lethal double-stranded DNA breaks in these CD33 targeted cells. Furthermore, in vivo studies in animal models of Ven-resistant AML demonstrated robust tumor regression and improved survival in cohorts receiving the Actimab-A Ven combination compared to Ven alone. The rationale for this clinical study is that the addition of Actimab-A will; 1) have a direct anti-tumor effect via double-stranded DNA breaks and 2) deplete Mcl-1 and BCL-XL making the AML cells more susceptible to Ven. We expect to initiate the trial and have preliminary proof of concept clinical data from this combination study by the end of 2020.
●
Phase 1 Actimab-A + 7+3 combination trial in patients with newly diagnosed AML with intermediate or high-risk cytogenetics or molecular markers. In February 2020, we announced plans to initiate this combination trial to add Actimab-A to 7+3, which is the standard of care chemotherapy regimen comprised of cytarabine and daunorubicin for patients with newly diagnosed AML who are fit for intensive therapy. As we have seen with the combination of Actimab-A + CLAG-M chemotherapy, we believe that Actimab-A will have synergistic and potentiating properties when added to 7+3, which causes DNA damage and has radiation sensitizing properties since daunorubicin is an anthracycline antibiotic that cytotoxically inhibits DNA replication and repair and RNA synthesis through inhibition of topoisomerase II. The rationale for studying Actimab-A in combination with 7+3 is the potential for both additive and synergistic effects due to the interplay of various mechanisms including DNA damage from alpha radiation and the chemotherapy combination, radiation sensitization, and prevention of DNA damage repair. We expect to initiate this Phase 1 trial by the end of 2020 and have proof of concept data in 2021.

Recent Developments
Impact of COVID–19 Pandemic
In December 2019, a novel
strain of COVID-19 was reported in China. Since then, COVID-19 has spread globally. The spread of COVID-19 from China to other
countries has resulted in the World Health Organization (WHO) declaring the outbreak of COVID-19 as a “pandemic,” or
a worldwide spread of a new disease, on March 11, 2020. Many countries around the world have imposed quarantines and restrictions
on travel and mass gatherings to slow the spread of the virus and have closed non-essential businesses, and as of the date of this
prospectus, many local jurisdictions continue to have such restrictions in place.
As many local jurisdictions
continue to have such restrictions in place, our ability to continue to operate our business may also be limited. Such events may
result in a period of business, supply and drug product manufacturing disruption, and in reduced operations, any of which could
materially affect our business, financial condition and results of operations. In response to COVID-19, we implemented remote working
and thus far have not experienced a significant disruption or delay in our operations as it relates to the clinical development
of our drug candidates. Such government-imposed precautionary measures may have been relaxed in certain countries or states, but
there is no assurance that more strict measures will be put in place again due to a resurgence in COVID-19 cases. Therefore, the
COVID-19 pandemic may continue to affect our operation, may further divert the attention and efforts of the medical community to
coping with COVID-19 and disrupt the marketplace in which we operate and may have a material adverse effect on our operations.
19
The spread of COVID-19,
which has caused a broad impact globally, may materially affect us economically. While the ultimate economic impact brought by,
and the duration of, the COVID-19 pandemic may be difficult to assess or predict, including new information which may emerge concerning
the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others, the pandemic has resulted significant
disruptions in the general commercial activity and the global economy and caused financial market volatility and uncertainty in
significant and unforeseen ways in the recent months. A continuation or worsening of the levels of market disruption and volatility
seen in the recent past could have an adverse effect on our ability to access capital, which could in the future negatively affect
our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our
business and the value of our common stock.
Currently, the Phase
3 SIERRA trial for our lead program, Iomab-B, continues to remain active at a majority of our clinical trial sites, with investigators
providing feedback that recruitment and enrollment will remain active because of the acute nature of the disease, the high unmet
needs of patients with relapsed or refractory AML, the potentially curative nature of BMT and the differentiated profile of Iomab-B.
Certain sites that had not been actively enrolling due to COVID-19 have resumed recruitment and enrollment, and we currently anticipate
that other sites that have not been actively enrolling due to COVID-19 will likely resume recruitment and enrollment in the summer
timeframe. We also believe our earlier stage clinical trials for our CD33 program will also continue to recruit and enroll patients
given the acute nature of relapsed or refractory AML. The continuation of the pandemic could adversely affect our planned clinical
trial operations, including our ability to conduct the trials on the expected timelines and recruit and retain patients and principal
investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if their geography is impacted
by the pandemic. Further, the continuation and/or resurgence of the COVID-19 pandemic could result in delays in our clinical trials
due to prioritization of hospital resources toward the pandemic, restrictions in travel, potential unwillingness of patients to
enroll in trials at this time, or the inability of patients to comply with clinical trial protocols if quarantines or travel restrictions
impede patient movement or interrupt healthcare services. In addition, we rely on independent clinical investigators, contract
research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying out
our preclinical studies and clinical trials, and the pandemic may affect their ability to devote sufficient time and resources
to our programs or to travel to sites to perform work for us.
Additionally, COVID-19
may result in delays in receiving approvals from local and foreign regulatory authorities, delays in necessary interactions
with IRB’s or Institutional Review Boards, local and foreign regulators, ethics committees and other important agencies and
contractors due to limitations in employee resources or forced furlough of government employees.
To date, COVID-19 has not
had a financial impact on our company. However, COVID-19 has caused severe disruptions in transportation and limited access to
our facility, resulting in limited support from our staff and professional advisors.
The ultimate impact from
COVID-19 on our business operations and financial results during 2020 will depend on, among other things, the ultimate severity
and scope of the pandemic, the pace at which governmental and private travel restrictions and public concerns about public gatherings
will ease, the rate at which historically large increases in unemployment rates will decrease, if at all, and whether, and the
speed with which the economy recovers. We are not able to fully quantify the impact that these factors will have on our financial
results during 2020 and beyond, but developments related to COVID-19 may materially affect us in 2020.
Reverse Stock Split
On April 29, 2020, we received
a deficiency letter from the NYSE American LLC, or the NYSE American, indicating that we are not in compliance with certain NYSE
American continued listing standards. The deficiency letter stated that our shares of common stock have been selling for a low
price per share for a substantial period of time. Pursuant to Section 1003(f)(v) of the Company Guide, the NYSE American staff
determined that our continued listing is predicated on us effecting a reverse stock split of our common stock or otherwise demonstrating
sustained price improvement within a reasonable period of time, which the staff determined to be until October 29, 2020.
20
The letter further stated
that as a result of the foregoing, we have become subject to the procedures and requirements of Section 1009 of the NYSE American
Company Guide, which could, among other things, result in the initiation of delisting proceedings, unless we cure the deficiency
in a timely manner. Our common stock will continue to be listed on the NYSE American while we attempt to regain compliance with
the listing standards, subject to our compliance with other continued listing requirements.
In addition, the NYSE American
has advised us that its policy is to immediately suspend trading in shares of, and commence delisting procedures with respect to,
a listed company if the market price of its shares falls below $0.06 per share at any time during the trading day.
On October 18, 2019, our
board of directors unanimously approved, subject to stockholder approval, an amendment to our certificate of incorporation to effect
a reverse stock split of our outstanding common stock by combining outstanding shares of common stock into a lesser number of outstanding
shares of common stock by a ratio of not more than 1-for-75 prior to December 18, 2020, with the exact ratio to be set within this
range by our board of directors at its sole discretion. On December 18, 2019, at our 2019 Annual Meeting of Stockholders, our stockholders
approved such proposed amendment to our certificate of incorporation. The primary intent of effecting the reverse stock split,
would be to ensure that we are able to maintain compliance with the listing standards of the NYSE American.
On August 7, 2020,
the Board unanimously approved a reverse stock split of its outstanding common stock by combining outstanding shares of common
stock into a lesser number of outstanding shares of common stock by a ratio of 1-for-30, and on August 10, 2020, we filed with
the Secretary of State of Delaware a certificate of amendment to its certificate of incorporation to effect the reverse stock split.
The reverse stock split became effective as of 5:00 p.m. Eastern Time on August 10, 2020, and our common stock began trading on
a split-adjusted basis when the market opened on August 11, 2020. Accordingly. all common share and per common share data in these
consolidated financial statements and related notes hereto have been retroactively adjusted to account for the effect of this reverse
stock split for all periods presented. In addition, at the effective time of the reverse stock split, the number of shares of our
common stock reserved for issuance upon exercise of all options and warrants to acquire common stock have been proportionally decreased,
and the exercise price of all options and warrants to acquire common stock have been proportionally increased. In addition, we
adjusted and proportionately decreased the total number of shares of our common stock that may be the subject of the future grants
under our stock plans.

each pre-funded warrant sold in the offering was $4.497. The pre-funded warrants are exercisable at an exercise price of
$0.003 per share and are subject to certain limitations on beneficial ownership. Gross proceeds from this offering were $31.6
million, before deducting underwriting discounts and commissions and other offering expenses payable by us. Net proceeds from
the offering were approximately $29.1 million. In June 2020, holders of 1.2 million pre-funded April 2020 warrants exercised
their warrants and received 1.2 million shares of common stock.
23
On June 19, 2020, we
issued and sold 1.9 million shares of common stock and pre-funded warrants to purchase 0.7 million shares of common stock. The
price to the public in this offering for each share of common stock was $9.75 and for each pre-funded warrant was $9.747. Each
pre-funded warrant has an exercise price of $0.003 per share and is exercisable immediately upon issuance. Gross proceeds from
this offering to us were $25.0 million, before deducting underwriting discounts and commissions and other offering expenses payable
us. Net proceeds from this offering were approximately $23.0 million.
In December 2018, we
entered into the Amended and Restated At Market Issuance Sales Agreement with B. Riley FBR, Inc. and JonesTrading Institutional
Services LLC, pursuant to which we conducted our at-the market program. During the six months ended June 30, 2020, we sold 0.3
million common shares through its at-the-market program, resulting in net proceeds of $2.5 million.
In October 2018,
we and Lincoln Park Capital Fund, LLC (“Lincoln Park”) entered into a purchase agreement and a registration rights
agreement, pursuant to which we have the right to sell to Lincoln Park shares of our common stock having an aggregate value of
up to $32.5 million, subject to certain limitations and conditions set forth in the agreement. During the six months ended June
30, 2020, we elected to sell to Lincoln Park 27 thousand shares and received $0.2 million.
Off-Balance Sheet Arrangements
We do not have any off-balance
sheet arrangements that have, or are reasonably likely to have a current or future effect on our financial condition, changes in
financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources that is material
to investors.
Critical Accounting Policies and Use of Estimates
Our management’s
discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which
have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. The preparation of
these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities
and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements during the reporting
periods. These items are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates
could occur in the future. We base our estimates on historical experience, known trends and events, and on various other factors
that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying
value of assets and liabilities that are not readily apparent from other sources. Changes in estimates are reflected in reported
results for the period in which they become known. Actual results may differ materially from these estimates under different assumptions
or conditions.
Our significant accounting
policies are described in detail in the notes to our consolidated financial statements appearing in our Annual Report filed on
Form 10-K for the year ended December 31, 2019.
Fair Value of Financial Instruments
Fair value is defined as
the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants.
A fair value hierarchy has been established for valuation inputs that gives the highest priority to quoted prices in active markets
for identical assets or liabilities and the lowest priority to unobservable inputs.
24
Research and Development Costs
Research and development
costs are expensed as incurred. These costs include the costs of manufacturing drug components and final drug product, the costs
of clinical trials, costs of employees and associated overhead, and depreciation and amortization costs related to facilities and
equipment. Research and development reimbursements are recorded by us as a reduction of research and development costs.
Share-Based Payments
We estimate the fair value
of each stock option award at the grant date by using the Black-Scholes option pricing model. The fair value determined represents
the cost for the award and is recognized over the vesting period during which an employee is required to provide service in exchange
for the award. We account for forfeitures of stock options as they occur.
Accounting Standards
Recently Adopted -
In August 2018, FASB issued
ASU 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820). The updated guidance improves the disclosure requirements
on fair value measurements, primarily associated with Level 3 fair value measurements and is effective for fiscal years, and interim
periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the standard
for disclosures modified or removed with a delay of adoption of the additional disclosures until their effective date. We adopted
this standard effective January 1, 2020 and the standard did not have a significant impact to our financial statements.
In November 2018, FASB
issued ASU 2018-18, C ollaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606,
which, among other things, provides guidance on how to assess whether certain collaborative arrangement transactions should be
accounted for under Topic 606. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal
years, beginning after December 15, 2019, with early adoption permitted. We adopted this standard effective January 1, 2020 and
the standard did not have a significant impact to our financial statements.
