Overview
We
are a drug discovery company that uses biomarker technology to identify enzyme targets associated with serious common diseases
and then designs novel compounds to attack those targets. Our product pipeline is primarily focused on inhibitors of protein phosphatases,
used alone and in combination with cytotoxic agents and/or x-ray and immune checkpoint blockers, and encompasses two major categories
of compounds at various stages of pre-clinical and clinical development that we believe have broad therapeutic potential not only
for cancer but also for other debilitating and life-threatening diseases.
We
have developed two series of pharmacologically active drugs, the LB-100 series and the LB-200 series. We believe that the mechanism
by which compounds of the LB-100 series affect cancer cell growth is different from cancer agents currently approved for clinical
use. Lead compounds from each series have activity against a broad spectrum of common and rarer human cancers in cell culture
systems. In addition, compounds from both series have anti-cancer activity in animal models of glioblastoma multiforme, neuroblastoma,
and medulloblastoma, all cancers of neural tissue. Lead compounds of the LB-100 series also have activity against melanoma, breast
cancer and sarcoma in animal models and enhance the effectiveness of commonly used anti-cancer drugs in these model systems. The
enhancement of anti-cancer activity of these anti-cancer drugs occurs at doses of LB-100 that do not significantly increase toxicity
in animals. It is therefore hoped that, when combined with standard anti-cancer regimens against many tumor types, our compounds
will improve therapeutic benefit without enhancing toxicity in humans.
Our
activities are subject to significant risks and uncertainties, including the need for additional capital, as described below.
We have not yet commenced any revenue-generating operations, do not have positive cash flows from operations, and are dependent
on periodic infusions of equity capital to fund our operating requirements.
Description
of Business; Research; Clinical Trial Activities
Our
primary focus is developing new treatments for human cancers for which better therapies are urgently needed.
Our
drug discovery process is based on discerning clues to potential new targets for disease treatments reported in the increasingly
large body of literature identifying the molecular variants which characterize human cancers and other non-cancer disorders. We
design drugs for which there are existing data suggesting that they may affect the altered pathways of the cancer cell and may
be given safely to humans. We seek to rapidly arrive at patentable structures through analysis of the literature rather than screening
of thousands of structures for activity against a particular biochemical pathway.
This
approach has led to the development of two classes of drugs for the treatment of cancer, consisting of protein phosphatase inhibitors
(PTase-i), designated by us as the LB-100 series of compounds, and histone deacetylase inhibitors (HDACi), designated by us as
the LB-200 series of compounds.
The
LB-100 series consists of novel structures which have the potential to be first in their class and may be useful in the treatment
of not only several types of cancer but also vascular and metabolic diseases. The LB-200 series contains compounds which have
the potential to be the most effective in its class and may be useful for the treatment of chronic hereditary diseases, such as
Gaucher’s disease, in addition to cancer and neurodegenerative diseases.
We
have demonstrated that lead compounds of both the LB-100 series and the LB-200 are active against a broad spectrum of human cancers
in cell culture and against several types of human cancers in animal models. The research on these compounds was initiated in
2006 under a Cooperative Research and Development Agreement or CRADA with the National Institute of Neurologic Disorders and Stroke
or NINDS of the National Institutes of Health or NIH dated March 22, 2006 that was subsequently extended through a series of amendments
until it terminated on April 1, 2013.

Effective
treatment of brain tumors depends upon the ability of compounds to penetrate a physiological barrier known as the “blood-brain
barrier” which protects the brain from exposure to potentially toxic substances in the blood. Because there is no certainty
that our compounds will be active against tumors confined to the brain, the LB-100 compounds have been studied against a variety
of common and rare cancer types and have been shown to potentiate the activity of standard anti-cancer drugs in animal models
of breast and pancreatic cancer, melanoma, pheochromocytomas and sarcomas. Because the LB-100 compounds appear to exert their
ability to improve the effectiveness of different forms of chemotherapy and radiation therapy by inhibiting a process upon which
most, if not all, cancer cell types depend on to survive treatment, we believe the LB-100 series of compounds may be useful against
most, if not all, cancer types.
The
LB-200 series consists of histone deacetylase inhibitors (HDACi). Many pharmaceutical companies are also developing drugs of this
type, and at least two companies have HDACi approved for clinical use, in both cases for the treatment of a type of lymphoma.
Despite this significant competition, we have demonstrated that our HDACi have broad activity against many cancer types, have
neuroprotective activity, and have anti-fungal activity. In addition, these compounds have low toxicity. LB-200 has not yet advanced
to the clinical stage and would require additional capital to fund further development. Accordingly, because of our focus on the
clinical development of LB-100 and analogs for cancer therapy as described below in more detail, we have decided not to actively
pursue the pre-clinical development of our LB-200 series of compounds at this time. At this time, we intend to only maintain our
composition of matter patents for LB-200.
Collaborations
with leading academic research centers in the United States, Europe and Asia have established the breadth of activity of LB-100
in pre-clinical models of several major cancers. There is considerable scientific interest in LB-100 because it exerts its activity
by a novel mechanism and is the first of its type to be evaluated so broadly in multiple animal models of cancer and now in human
beings. LB-100 is one of a series of serine/threonine phosphatase (s/t ptase) inhibitors designed by us. The s/t ptases are ubiquitous
enzymes that regulate many cell signaling networks important to cell growth, division and death. The s/t ptases have long been
appreciated as potentially important targets for anti-cancer drugs. However, because of the multi- functionality of these enzymes,
it had been widely held that pharmacologic inhibitors of s/t ptases would be too toxic to allow their development as anti-cancer
treatments, but we have shown that this is not the case. LB-100 was well-tolerated at doses associated with objective regression
(significant tumor shrinkage) and/or the arresting of tumor progression in patients with progressive cancers.
Pre-clinical
studies showed that LB-100 itself inhibits a spectrum of human cancers and that combined with standard cytotoxic drugs and/or
radiation, LB-100 potentiates their effectiveness against hematologic and solid tumor cancers without enhancing toxicity. Given
at very low doses in animal models of cancer, LB-100 markedly increased the effectiveness of a PD-1 blocker, one of the widely
used new immunotherapy drugs. This finding raises the possibility that LB-100 may further expand the value of the expanding field
of cancer immunotherapy.
We
completed a Phase 1 clinical trial of LB-100 to evaluate its safety that showed it is associated with antitumor activity in humans
at doses that are readily tolerable. Responses included objective regression (tumor shrinkage) lasting for 11 months of a pancreatic
cancer and cessation of growth (stabilization of disease) for 4 months or more of 9 other progressive solid tumors out of 20 patients
who had measurable disease. As Phase 1 clinical trials are fundamentally designed to determine safety of a new compound in humans,
we were encouraged by these results. The next step is to demonstrate in Phase 2 clinical trials the efficacy of LB-100 in one
or more specific tumor types, against which the compound has well documented activity in pre-clinical models.
Clinical
Trial Agreements
Moffitt
Cancer Center Clinical Trial Research Agreement
Effective
August 20, 2018, we entered into a Clinical Trial Research Agreement with the Moffitt Cancer Center and Research Institute Hospital
Inc., Tampa, Florida, effective for a term of five years, unless terminated earlier by us pursuant to 30 days written notice.
Pursuant to the Clinical Trial Research Agreement, Moffitt agreed to conduct and manage a Phase 1b/2 clinical trial to evaluate
the therapeutic benefit of our lead anti-cancer clinical compound LB-100 to be administered intravenously in patients with low
or intermediate-1 risk myelodysplastic syndrome (MDS).
- 5 -
In
November 2018, we received approval from the FDA for our Investigational New Drug Application to conduct a Phase 1b/2 clinical
trial to evaluate the therapeutic benefit of LB-100 in patients with low and intermediate-1 risk MDS who have failed or are intolerant
of standard treatment. Patients with MDS, although usually older, are generally well except for severe anemia requiring frequent
blood transfusions. This Phase 1b/2 clinical trial utilizes LB-100 as a single agent in the treatment of patients with low and
intermediate-1 risk MDS, including patients with del(5q) myelodysplastic syndrome (del5qMDS) failing first line therapy. The bone
marrow cells of patients with del5qMDS are deficient in PP2A by virtue of an acquired mutation and are especially vulnerable to
further inhibition of PP2A by LB-100. The clinical trial began at a single site in April 2019 and the first patient was entered
into the clinical trial in July 2019. A total enrollment of 41 patients is planned. An interim analysis will be done after the
first 21 patients are entered. If there are 3 or more responders but fewer than 7, an additional 20 patients will be entered.
If at any point there are 7 or more responders, this will be sufficient evidence to support continued development of LB-100 for
the treatment of low and intermediate-1 risk MDS. Recruitment has been slow and the Covid-19 pandemic has further reduced recruitment
of patients into the protocol. At the current rate of accrual, the trial would be completed over a period of four years from its
initiation, with the final analysis and reporting expected by July 2023. However, with additional funds, our objective would be
to add two additional MDS centers to the Phase 2 portion of the study to accelerate patient accrual, with the goal of an earlier
reporting date.
Spanish
Sarcoma Group Collaboration Agreement
As
of July 31, 2019, we entered into a Collaboration Agreement for an Investigator-Initiated Clinical Trial with the Spanish Sarcoma
Group (Grupo Español de Investigación en Sarcomas or “GEIS”), Madrid, Spain, to carry out a study entitled
“Randomized phase I/II trial of LB-100 plus doxorubicin vs. doxorubicin alone in first line of advanced soft tissue sarcoma”.
The purpose of this clinical trial is to obtain information about the efficacy and safety of LB-100 combined with doxorubicin
in soft tissue sarcomas. Doxorubicin is the global standard for initial treatment of advanced soft tissue sarcomas (“ASTS”).
Doxorubicin alone has been the mainstay of first line treatment of ASTS for over 40 years, with little therapeutic gain from adding
cytotoxic compounds to or substituting other cytotoxic compounds for doxorubicin. In animal models, LB-100 consistently enhances
the anti-tumor activity of doxorubicin without apparent increases in toxicity.
GEIS
has a network of referral centers in Spain and across Europe that have an impressive track record of efficiently conducting innovative
studies in ASTS. We agreed to provide GEIS with a supply of LB-100 to be utilized in the conduct of this clinical trial, as well
as to provide funding for the clinical trial. The goal was to enter the first patient during the quarter ending December 31, 2020,
with approximately 150 patients to be enrolled over two years. Advanced sarcoma is a very aggressive disease. The design of the
study assumes a median progression free survival (PFS, no evidence of disease progression or death from any cause) of 4.5 months
in the doxorubicin arm and an alternative median PFS of 7.5 months in the doxorubicin plus LB-100 arm to demonstrate a statistically
significant decrease in relative risk of progression or death by adding LB-100. There is a planned interim analysis of the primary
endpoint when about half of the 102 events required for final analysis is reached.
In
order to manufacture a new inventory supply of LB-100 for the GEIS clinical trial, the Company has engaged a number of vendors
to carry out the multiple tasks needed to make and gain approval of a new clinical product for investigational study in Spain.
These tasks include the synthesis under good manufacturing practices (GMP) of the active pharmacologic ingredient (API), with
documentation of each of the steps involved by an independent auditor. The API is then transferred to a vendor that prepares the
clinical drug product (DP), also under GMP conditions documented by an independent auditor. The DP is then sent to a vendor to
test for purity and sterility, provide appropriate labels, store the drug, and distribute the drug to the clinical centers for
use in the clinical trials. A formal application documenting all steps taken to prepare the DP for clinical use must be submitted
to the appropriate regulatory authorities for review and approval before being used in a clinical trial.
The
Company estimates that this program to provide new inventory of the DP for the Spanish sarcoma study, and potentially for subsequent
multiple trials within the European Union, will cost from $600,000 and $700,000. The Company’s remaining aggregate commitments
under this program, less amounts previously paid to date, totaled approximately $300,000 as of December 31, 2020, which are expected
to be incurred through June 30, 2021.
- 6 -
We
had previously expected that this clinical trial would commence during the quarter ended June 30, 2020. However, during July 2020,
the Spanish regulatory authority advised us that although it had approved the scientific and ethical basis of the protocol, it
required that we manufacture new inventory of LB-100 under current Spanish pharmaceutical manufacturing standards. These regulations
were adopted subsequent to the production of our existing LB-100 inventory. We are in the process of obtaining approval from the
European Union regulatory authorities for new inventory of LB-100. Accordingly, the clinical trial is now estimated to begin during
the quarter ending September 30, 2021 and to be completed by the quarter ending September 30, 2024. The interim analysis is expected
in June 2023 and could indicate either inferiority or superiority of LB-100 plus doxorubicin as compared to doxorubicin alone.
A positive study would have the potential to change the standard therapy for this disease after four decades of failure to improve
the marginal benefit of doxorubicin alone.
NCI
Pharmacologic Study
During
the fourth quarter of 2019, the National Cancer Institute (NCI) enrolled the first two patients of a planned eight patient pharmacologic
study of the ability of LB-100 to enter the brain and penetrate recurrent brain tumors in patients where surgical removal of the
cancers is indicated (clinical trials registry NCT03027388). This study is being conducted and funded by the NCI under a Cooperative
Research and Development Agreement with us; additional information will be reported by us as it is provided by the NCI.
Primary
malignant brain tumors (gliomas) are very challenging to treat. Radiation combined with the chemotherapeutic drug temozolomide
has been the mainstay of therapy of the most aggressive gliomas (glioblastoma multiforme or GBM) for decades, with some further
benefit gained by the addition of one or more anti-cancer drugs, but without major advances in overall survival for the majority
of patients. In animal models of GBM, our novel protein phosphatase inhibitor LB-100 enhances the effectiveness of radiation,
temozolomide chemotherapy treatments and immunotherapy, raising the possibility that LB-100 may improve outcomes of standard GBM
treatment in the clinic. Although LB-100 has proven safe in patients at doses associated with apparent anti-tumor activity against
several human cancers arising outside the brain, the ability of LB-100 to penetrate tumor tissue arising in the brain is not known.
Unfortunately, many drugs potentially useful for GBM treatment do not enter the brain in amounts necessary for anti-cancer action.
The
NCI study is designed to determine the extent to which LB-100 enters recurrent malignant gliomas. Patients having surgery to remove
one or more tumors will receive one dose of LB-100 prior to surgery and have blood and tumor tissue analyzed to determine the
amount of LB-100 present and to determine whether the cells in the tumors show the biochemical changes expected to be present
if LB-100 reaches its molecular target. The goal is to obtain data in up to eight patients. As a result of the innovative design
of the NCI study, data from so few patients should be sufficient to provide a sound rationale for conducting a larger clinical
trial to determine the effectiveness of adding LB-100 to the standard treatment regimen for GBMs.
Clinical
Research Support Agreement with City of Hope National Medical Center
Effective
January 18, 2021, we executed a Clinical Research Support Agreement with City of Hope National Medical Center, an NCI-designated
comprehensive cancer center, and City of Hope Medical Foundation (collectively, “City of Hope”), to carry out a Phase
1b clinical trial of our first-in-class protein phosphatase inhibitor, LB-100, combined with a standard regimen for untreated,
extensive stage-disease small cell lung cancer (ED-SCLC). LB-100 will be given in combination with carboplatin, etoposide and
atezolizumab, an FDA approved but marginally effective regimen, to previously untreated ED-SCLC patients. The dose of LB-100 will
be escalated with the standard fixed doses of the 3-drug regimen to reach a recommended Phase 2 dose (RP2D). Patient entry will
be expanded so that a total of 12 patients will be evaluable at the RP2D to confirm the safety of the LB-100 combination and to
look for potential therapeutic activity as assessed by objective response rate, duration of overall response, progression-free-survival
and overall survival.
Small
cell lung cancer (SCLC) comprises about 15% of all lung cancers worldwide with about 30,000 new cases annually in the United States.
Although this aggressive neuroendocrine tumor is more sensitive to cytotoxic chemotherapy and radiation than the most common type
of lung cancer, SCLC patients soon relapse after treatment and have a dismal prognosis. Recently, the addition of an immune blocker,
atezolizumab, to carboplatin plus etoposide showed for the first time in 20 years modest improvement in median progression- free
survival from 4.3 to 5.2 months and in median overall survival from 10.3 to 12.3 months. In animal models, LB-100 significantly
enhances the antitumor activity of cytotoxic chemotherapy in general and in particular the combination of carboplatin and etoposide
against SCLC cells without enhancing toxicity.
- 7 -
If
the extensive preclinical data showing LB-100 increases the effectiveness of chemotherapy applies to patients, the Company believes
evidence of therapeutic benefit of LB-100 added to standard treatment of this very aggressive cancer could be revealed even in
this early clinical trial paving the way for a randomized Phase 3 study. Perhaps even more important to the Company’s clinical
development of LB-100, evidence in this clinical trial of potentiation of cytotoxic therapy without an increase in toxicity simply
by the addition of LB-100 would justify clinical investigation of the added benefit of adding LB-100 to many widely used “standard”
cytotoxic regimens for a host of cancers.
The
Company estimates that from 24 to 30 patients will be needed to complete this clinical trial, at an estimated cost of $2,500,000
to $2,900,000, respectively. If a significant number of patients fail during the dose-escalation process, an increase of up to
12 patients would likely be necessary, at an estimated additional cost of $800,000.
The
clinical trial is planned to commence during the quarter ending June 30, 2021, with patient accrual expected to take approximately
18 to 24 months to conduct. If LB-100 does potentiate the benefit of the standard regimen, some evidence could be noted at 12
months into the clinical trial, but an assessment of potential increased activity is likely to require at least 24 months.
Clinical
Trial Monitoring Agreements
On
September 12, 2018, we finalized a work order agreement with Theradex Systems, Inc. (“Theradex”), an international
contract research organization, to monitor the Phase 1b/2 clinical trial being managed and conducted by Moffitt. The clinical
trial began in April 2019 and the first patient was entered into the clinical trial in July 2019. At the current rate of accrual,
the trial would be completed over a period of four years from its initiation, with the final analysis and reporting expected by
July 2023. Costs under this work order agreement are estimated to be approximately $954,000, with such payments expected to be
divided approximately 94% to Theradex for services and approximately 6% for payments for pass-through costs.
On
February 5, 2021, we signed a new work order agreement with Theradex to monitor the City of Hope investigator-initiated clinical
trial in small cell lung cancer in accordance with FDA requirements for oversight by the sponsoring party. The Company estimates
that it will incur approximately $335,000 of costs under this work order agreement through September 30, 2023.
Patent
and License Agreements
On
March 22, 2018, we entered into a Patent Assignment and Exploitation Agreement with INSERM TRANSFERT SA, acting as delegatee of
the French National Institute of Health and Medical Research, for the assignment to us of INSERM’S interest in United States
Patent No. 9,833,450 entitled “Oxabicyloheptanes and Oxabicycloheptenes for the Treatment of Depressive and Stress Disorders,”
which was filed with the United States Patent and Trademark Office in the name of INSERM and us as co-owners on February 19, 2016
and granted on December 5, 2017, and related patent applications and filings. INSERM is a French public institution dedicated
to research in the field of health and medicine that had previously entered into a Material Transfer Agreement with us to allow
INSERM to conduct research on our proprietary compound LB-100 and/or its analogs for the treatment of depressive or stress disorders
in humans. Pursuant to the Agreement, we have agreed to make certain milestone payments to INSERM aggregating up to $1,750,000
upon achievement of development milestones and up to $6,500,000 upon achievement of commercial milestones. We also agreed to pay
INSERM certain commercial royalties on net sales of products attributed to the Agreement. The exploitation of this patent for
the treatment of depressive and stress disorders in humans will require substantial additional capital and/or a joint venture
or other type of business arrangement with a pharmaceutical company with substantially greater capital and business resources
than those available to us. As there can be no assurances that we will be able to obtain the capital or business resources necessary
to focus on the exploitation of this patent, it is uncertain when we may reach any of the development or commercialization milestones
under the Agreement, if at all.
- 8 -
Effective
April 2, 2018, we entered into a consulting agreement for a term of two years with Liberi Life Sciences Consultancy BV, located
in The Netherlands, for consulting and advisory services with respect to sales and licensing, as well as the procurement of investors
in China, Japan and South Korea. The Consulting Agreement was extended for an additional period of one year. The Consulting Agreement
provided for the payment of a fixed, one-time retainer of EURO 15,000 (US $18,348), which was paid on April 5, 2018, and 2.5%
of the net payments received by us from sales of products or licensing activities arising directly and exclusively from leads
generated by the advisor during the term of the Consulting Agreement, and any investors introduced to us by the advisor that results
in an investment in us during the term of the Consulting Agreement.
Effective
August 20, 2018, we entered into an Exclusive License Agreement with Moffitt. Pursuant to the License Agreement, Moffitt granted
us an exclusive license under certain patents owned by Moffitt relating to the treatment of MDS and a non-exclusive license under
inventions, concepts, processes, information, data, know-how, research results, clinical data, and the like (other than the Licensed
Patents) necessary or useful for the practice of any claim under the Licensed Patents or the use, development, manufacture or
sale of any product for the treatment of MDS which would otherwise infringe a valid claim under the Licensed Patents. We were
obligated to pay Moffitt a non-refundable license issue fee of $25,000 after the first patient is entered into a Phase 1b/2 clinical
trial to be managed and conducted by Moffitt. The clinical trial began at a single site in April 2019 and the first patient was
entered into the clinical trial in July 2019. We are also obligated to pay Moffitt an annual license maintenance fee of $25,000
commencing on the first anniversary of the Effective Date and every anniversary thereafter until we commence payment of minimum
royalty payments. We have also agreed to pay non-refundable milestone payments to Moffitt, which cannot be credited against earned
royalties payable by us, based on reaching various clinical and commercial milestones aggregating $1,897,000, subject to reduction
by 40% under certain circumstances relating to the status of Valid Claims, as such term is defined in the License Agreement. As
of December 31, 2020, no milestones had yet been attained.
We
will be obligated to pay Moffitt earned royalties of 4% on worldwide cumulative net sales of royalty-bearing products, subject
to reduction to 2% under certain circumstances, on a quarterly basis, with a minimum royalty payment of $50,000 in the first four
years after sales commence, and $100,000 in year five and each year thereafter, subject to reduction by 40% under certain circumstances
relating to the status of Valid Claims, as such term is defined in the License Agreement. Our obligation to pay earned royalties
under the License Agreement commences on the date of the first sale of a royalty-bearing product, and shall automatically expire
on a country-by-country basis on the date on which the last valid claim of the Licensed Patents expires, lapses or is declared
invalid, and the obligation to pay any earned royalties under the License Agreement shall terminate on the date on which the last
valid claim of the Licensed Patents expires, lapses, or is declared to be invalid in all countries.
Other
Significant Agreements and Contracts
Effective
October 18, 2013, we entered into a Materials Cooperative Research and Development Agreement (M-CRADA) with the NINDS of the NIH
for a term of four years. The Surgical Neurology Branch of NINDS is conducting research characterizing a variety of compounds
proprietary to us and is examining the potential of the compounds for anti-cancer activity, reducing neurological deficit due
to ischemia and brain injury, and stabilizing catalytic function of misfolded proteins for inborn brain diseases. Under an M-CRADA,
a party provides research material, in this case proprietary compounds from our pipeline, for study by scientists at NIH. The
exchange of material was for research only and did not imply any endorsement of the material on the part of either party. Under
the M-CRADA, the NIH grants a collaborator an exclusive option to elect an exclusive or non-exclusive commercialization license.
On
December 24, 2013, we entered into an agreement with NDA Consulting Corp. for consultation and advice in the field of oncology
research and drug development. As part of the agreement, NDA also agreed to cause its president, Dr. Daniel D. Von Hoff, M.D.,
to become a member of our Scientific Advisory Committee. The term of the agreement was for one year and provided for a quarterly
cash fee of $4,000. The agreement has been automatically renewed for additional one-year terms on its anniversary date since 2014.
Consulting and advisory fees charged to operations pursuant to this agreement for the years ended December 31, 2020 and 2019 were
$16,000 and $16,000, respectively.

Effective
September 14, 2015, we entered into a Collaboration Agreement with BioPharmaWorks, pursuant to which we engaged BioPharmaWorks
to perform certain services for us. Those services include, among other things: (a) assisting us to (i) commercialize our products
and strengthen our patent portfolio, (ii) identify large pharmaceutical companies with potential interest in our product pipeline,
and (iii) prepare and deliver presentations concerning our products; (b) at the request of the Board of Directors, serving as
backup management for up to three months should our Chief Executive Officer and scientific leader be temporarily unable to carry
out his duties; (c) being available for consultation in drug discovery and development; and (d) identifying providers and overseeing
tasks relating to clinical use and commercialization of new compounds.
BioPharmaWorks
was founded in 2015 by former Pfizer scientists with extensive multi-disciplinary research and development and drug development
experience. The Collaboration Agreement was for an initial term of two years and automatically renews for subsequent annual periods
unless terminated by a party not less than 60 days prior to the expiration of the applicable period. In connection with the Collaboration
Agreement, we agreed to pay BioPharmaWorks a monthly fee of $10,000, subject to our right to pay a negotiated hourly rate in lieu
of the monthly payment and agreed to issue to BioPharmaWorks certain equity-based compensation. In November 2016, it was mutually
agreed to suspend services and payments under the Collaboration Agreement, without extending its term, for the period from November
1, 2016 through March 31, 2017. The Collaboration Agreement resumed as scheduled on April 1, 2017. In April 2018, it was again
mutually agreed to suspend services and payments under the Collaboration Agreement, without extending its term, for the period
from February 1, 2018 through the September 13, 2019 anniversary date. In February 2019, we subsequently agreed to resume the
Collaboration Agreement with BioPharmaWorks effective March 1, 2019, and the Collaboration Agreement is currently in effect.
Effective
August 12, 2020, we entered into a Master Service Agreement with the Foundation for Angelman Syndrome Therapy (FAST) to collaborate
in supporting preclinical studies of the potential benefit of LB-100 in a mouse model of Angelman Syndrome (AS) as reported in
The Proceedings of The National Academy of Science (Wang et al, June 3, 2019). The preclinical studies will take place at The
University of California - Davis under the direction of Dr. David Segal, an internationally recognized leader in AS research.
If the preclinical studies confirm that LB-100 reduces AS signs in rodent models, we have agreed to enter into discussions with
FAST with respect to possible collaborations to most efficiently assess the benefit of LB-100 in patients with AS, which is a
rare disease affecting an estimated one out of 12,000 to one out of 20,000 persons in the United States. The genetic cause of
AS, reduced function of a specific maternal gene called Ube3, has been understood for some time, but the molecular abnormality
resulting from the genetic lesion has now been shown to be increased concentrations of protein phosphatase 2A (PP2A), a molecular
target of our investigational compound, LB-100. We agreed to provide FAST with a supply of LB-100 to be utilized in the conduct
of this study, which is initially expected to be completed within three years. Conditioned on FAST’s completion of this
study, we have agreed to pay FAST five percent (5%) of all proceeds, as defined in the Master Service Agreement, received by us,
up to a maximum of $250,000 from the exploitation of the study results.
Future
Clinical Trials
Presented
below are clinical trials that we would currently consider conducting over the next few years. We expect that these potential
clinical trials, and the details thereof, will change over time as we obtain more clinical information on LB-100. Our ability
to conduct these clinical trials is subject to the availability of sufficient additional financial resources.
(1)
A Phase 1b/2 randomized clinical trial in previously untreated patients with small cell lung cancer (SCLC) comparing the standard
regimen, carboplatin/etoposide/atezolizumab, with and without LB-100. The malignant cells of this uniformly rapidly fatal lung
cancer are genetically sensitive to PP2A inhibition (by a process termed “synthetic lethality”).
(2)
A Phase 1b/2 randomized clinical trial in patients adding LB-100 to PD-1 inhibitors against one of several cancers in which PD-1
inhibitors alone have definite but modest activity.
- 10 -
The
Phase 1b/2 clinical trials in SCLC and in LB-100 plus a PD-1 inhibitor in yet to be specified solid tumors will require additional
financing in excess of that currently budgeted to fund a Phase 1b/2 clinical trial in myelodysplastic syndrome that began in April
2019, and/or partnering relationships with other pharmaceutical companies, in order for us to undertake and complete such clinical
studies. We are in discussions with various parties with respect to the financing of these clinical studies, although there can
be no assurances that we will be able to obtain such financing and/or partnering relationships on acceptable terms or at all.
Our longer-term objective is to secure one or more strategic partnerships with pharmaceutical companies with major programs in
cancer research and drug development.
Intellectual
Property
Our
products will ultimately be based on our intellectual property and are expected to be covered by our patents. These patents now
cover sole rights to the composition and synthesis of the LB-100 and LB-200 series of drugs, with coverage of the LB-200 series
now limited to those patents issued in the United States. Joint patent applications with the NIH have been filed for the treatment
of glioblastoma multiforme, medulloblastoma, and neuroblastoma. We have also filed patent applications for the use of certain

The
Market
Anti-Cancer
Drugs
We
have developed two series of pharmacologically active drugs, the LB-100 series and the LB-200 series. We believe that the mechanism
by which compounds of the LB-100 series affect cancer cell growth is different from cancer agents currently approved for clinical
use. Lead compounds from each series have activity against a broad spectrum of common and rarer human cancers in cell culture
systems. In addition, compounds from both series have anti-cancer activity in animal models of glioblastoma multiforme, neuroblastoma,
and medulloblastoma, all cancers of neural tissue. Lead compounds of the LB-100 series also have activity against melanoma, breast
cancer and sarcoma in animal models and enhance the effectiveness of commonly used anti-cancer drugs in these model systems. The
enhancement of anti-cancer activity of these anti-cancer drugs occurs at doses of LB-100 that do not significantly increase toxicity
in animals. It is therefore hoped that when combined with standard anti-cancer regimens against many tumor types, our compounds
will improve therapeutic benefit without enhancing toxicity in humans.
- 13 -
Marketing
Plan
Our
primary goal to date has been to take our primary compound, LB-100, through Phase 2 clinical trials. Because of the novelty and
spectrum of activity of LB-100, we believe it is reasonably likely we may find a partner in the pharmaceutical industry with interest
in this compound at some stage of its clinical development. However, we would prefer to delay the partnering/licensing decision
until the potential value of our products are augmented by demonstrating there is no impediment to clinical evaluation and a therapeutic
dose level is determined in clinical trials. Demonstration of clinical usefulness would be expected to substantially increase
the value of our product.
Research
and Development
Further
development of lead compounds in addition to LB-100 will require pharmacokinetic/ pharmacodynamic characterization (i.e., how
long a drug persists in the blood and how long the drug is active at the intended target) and large animal toxicologic evaluation
under conditions meeting FDA requirements. Most anti-cancer drugs fail in development because of unacceptable toxicity. However,
by analogy with mechanistically related compounds, there is good reason to believe that lead compounds in addition to LB-100 will
be able to be given to humans safely by routes and at doses resulting in concentration of drug producing anti-cancer activity
in animal model systems.
One
of our most valuable resources is our scientific team, a coalition of various experts brought together through contracts and other
collaborative arrangements. The team has expertise in cancer biology, proteomics (cancer biomarkers), medicinal and synthetic
chemistry, pharmacology, clinical oncology and drug evaluation. In a relatively short period of time and at low cost, this group
has developed lead compounds of two different classes of drugs that are positioned for development as new treatments for several
types of cancer.
Product
Development
We
are subject to FDA regulations as it conducts clinical trials. Additionally, any product for which we obtain marketing approval,
along with the manufacturing processes, post-approval clinical data and promotional activities for such product, will be subject
to continual review and periodic inspections by the FDA and other regulatory bodies. Even if regulatory approval of a product
is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or contain
requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. Later discovery
of previously unknown problems with our products, including unanticipated adverse events or adverse events of unanticipated severity
or frequency, manufacturer or manufacturing processes, or failure to comply with regulatory requirements, may result in restrictions
on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recall, fines,
suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties.
Competition
The
life sciences industry is highly competitive and subject to rapid and profound technological change. Our present and potential
competitors include major pharmaceutical companies, as well as specialized biotechnology and life sciences firms in the United
States and in other countries. Most of these companies have considerably greater financial, technical and marketing resources
than we do. Additionally, mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more
resources being concentrated in our competitors. Our existing or prospective competitors may develop processes or products that
are more effective than ours or be more effective at implementing their technologies to develop commercial products faster. Our
competitors may succeed in obtaining patent protection and/or receiving regulatory approval for commercializing products before
we do. Developments by our competitors may render our product candidates obsolete or non-competitive.
- 14 -
We
also experience competition from universities and other research institutions, and we are likely to compete with others in acquiring
technology from those sources. There can be no assurance that other organizations will not develop technologies with significant
advantages over those that we are seeking to develop. Any such development could harm our business.
We
compete with universities and other research institutions engaged in research in these areas. Many of our competitors have greater
technical and financial resources than we do.
Our
ability to compete successfully is based on numerous factors, including:
●
the
cost-effectiveness of any product that we ultimately commercialize relative to competing products;
●
the
ease of use and ready availability of any product that we bring to market; and
●
the
relative speed with which we are able to bring any product resulting from its research to market in our target markets.
If
we are unable to distinguish our products from competing products, or if competing products reach the market first, we may be
unable to compete successfully with current or future competitors.
Employees
and Human Capital Resources
As
of March 12, 2021, we had three full-time employees and one part-time employee. We consider our relationship with our employees
to be good. Our future performance depends significantly upon the continued service of our key personnel and our ability to attract
highly skilled employees. We provide our employees with opportunities for equity ownership.
Facilities
As
of March 12, 2021, we do not operate any facilities, but contract out research and development activities, drug production, and
drug storage to various commercial laboratories, drug manufacturers and storage facilities.
Government
Regulation
Studies
done under the CRADA were carried out in compliance with applicable Statutes, Executive Capital Orders, HHS regulations and all
FDA, CDC, and NIH policies as specified in Article 13, 13.1 and 13.2, of the PHS CRADA.
Our
business is subject to the regulations of the FDA as it conducts clinical trials. Clinical trials are research studies to answer
specific questions about new therapies or new ways of using known treatments. Clinical trials determine whether new drugs or treatments
are both safe and effective and the FDA has determined that carefully conducted clinical trials are the fastest and safest way
to find treatments that work in people.
The
FDA also requires that an independent review body consider the benefits and risks of a clinical trial and grant approval for the
proposed study including selecting of initial doses, plans for escalation of dose, plans for modification of dose if toxicity
is encountered, plans for monitoring the wellbeing of individuals participating in the study, and for defining and measuring,
to the extent possible, any untoward effects related to drug administration. Serious adverse effects, such as life-threatening
toxicities and death, are immediately reportable to the review body and to the FDA. To minimize risk when studying a new drug,
the initial dose is well below that expected to cause any toxicity. No more than three patients are entered at a given dose. In
general, a dose is not escalated within an individual patient. Once safety is established by the absence of toxicity or low toxicity
in a group of three patients, a planned higher dose is then evaluated in a subsequent group of three individuals and so on until
dose-limiting toxicity is encountered. The dose level producing definite but acceptable toxicity is then selected as the dose
level to be evaluated in Phase 2 trials. Thus, the goal of Phase 1 studies is to determine the appropriate dose level for evaluation
of drug efficacy in patients with the same type of tumor at comparable stages of progression for which no beneficial treatment
is established.
- 15 -
In
addition to regulations imposed by the FDA, depending on our future activities, we may become subject to regulation under various
federal and state statutes and regulations, such as the Occupational Safety and Health Act, the Environmental Protection Act,
the Toxic Substances Control Act, the Research Conservation and Recovery Act, national restrictions on technology transfer, and
import, export and customs regulations. From time to time, other federal agencies and congressional committees have indicated
an interest in implementing further regulation of biotechnology applications. We are not able to predict whether any such regulations
will be adopted or whether, if adopted, such regulations will apply to our business, or whether we or our collaborators would
be able to comply with any applicable regulations.
In
addition, as we intend to market our products in international markets, we may be required to obtain separate regulatory approvals
from the European Union and many other foreign jurisdictions. Approval by the FDA does not ensure approval by regulatory authorities
in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other
foreign countries or by the FDA. We may not be able to file for regulatory approvals and may not receive necessary approvals to
commercialize our products in any market.
Legal
Proceedings
We
may be involved from time to time in ordinary litigation, negotiation, and settlement matters that will not have a material effect
on our operations or finances. We are not currently party to any material legal proceedings, and we are not aware of any pending
or threatened litigation against us.
