RTGel leverages the physiologic flow of urine to provide a natural exit from the body.
−Removed: We believe that RTGel , when formulated with an active drug, may allow for the improved efficacy of treatment of various types of urothelial and specialty cancers without compromising the safety of the patient or interfering with the natural flow of fluids in the urinary tract.
−Removed: Jelmyto is our novel sustained-release RTGel -based formulation of mitomycin that we have developed for the treatment of low-grade UTUC. On April 15, 2020, the FDA approved our new drug application (“NDA”) for Jelmyto (mitomycin) for pyelocalyceal solution, formerly known as UGN-101, for the treatment of adult patients with low-grade UTUC.
+Added: We believe that RTGel 
+Added: ®, when formulated with an active drug, may allow for the improved efficacy of treatment of various types of urothelial and specialty cancers and urologic diseases without compromising the safety of the patient or interfering with the natural flow of fluids in the urinary tract.
+Added: achieves this by:
+Added: increasing the exposure of active drugs in the bladder and upper urinary tract by significantly extending the dwell time of the active drug while conforming to the anatomy of the bladder and the upper urinary tract, which allows for enhanced drug tissue coverage.
+Added: For example, the average dwell time of the standard mitomycin water formulation, currently used as adjuvant treatment, in the upper urinary tract is approximately five minutes, compared to up to six hours when mitomycin is formulated with RTGel ;
+Added: administering higher doses of an active drug than would otherwise be possible using standard water-based formulations.
+Added: For instance, it is only possible to dissolve 0.5 mg of mitomycin in 1 mL of water while it is possible to formulate up to 8 mg of mitomycin with 1 mL of RTGel ;
+Added: maintaining the active drug’s molecular structure and mode of action.
+Added: These characteristics of RTGel  enable sustained release of mitomycin in the urinary tract for both Jelmyto and UGN-102.
+Added: Further, RTGel may be particularly effective in the bladder and upper urinary tract where tumor visibility and access are challenging, and where there exists a significant amount of urine flow and voiding.
+Added: We believe that these characteristics of RTGel may prove useful for the local delivery of active drugs to other bodily cavities in addition to the bladder and upper urinary tract.
+Added: Jelmyto 
+Added: On April 15, 2020, the FDA approved our new drug application (“NDA”) for Jelmyto (mitomycin) for pyelocalyceal solution, formerly known as UGN-101, for the treatment of adult patients with low-grade UTUC.

+Added: We have implemented processes to help make Jelmyto preparation and administration safe and seamless for practitioners and patients, including entering into an agreement with a major national specialty pharmacy under which the pharmacy, following receipt of a patient prescription, prepares and dispenses the Jelmyto admixture on our behalf.
+Added: In September 2022, the FDA authorized an extension of the in-use period for Jelmyto admixture from eight hours to 96 hours (four days) following reconstitution of the product, adding convenience and flexibility in managing patient care.
In October 2020, a Medicare C-Code was issued for Jelmyto .
−Removed: The Centers for Medicare & Medicaid Services established a permanent and product-specific J-code for Jelmyto that took effect on January 1, 2021 and replaced the C-Code. We are also launching a registry to capture data and evaluate real world outcomes in patients with UTUC that have been or will be treated with Jelmyto.
+Added: The Centers for Medicare & Medicaid Services established a permanent and product-specific J-code for Jelmyto that took effect on January 1, 2021 and replaced the C-Code. We have also launched a registry to capture data and evaluate real world outcomes in patients with low-grade UTUC that have been or will be treated with Jelmyto.
The purpose of the registry is to study the use of Jelmyto in clinical practice in the United States and address specific clinical questions.
−Removed: We are evaluating the safety and efficacy of UGN-102, our novel sustained-release formulation of mitomycin for the treatment of low-grade intermediate risk NMIBC.
+Added: In the first two full fiscal years following the initiation of our commercial launch of Jelmyto in June 2020, we have experienced a moderate decline in revenue during the third quarter from the preceding quarter.
+Added: We believe this result is primarily attributable to the nature of low-grade disease, which does not require immediate treatment and therefore we believe there is an impact in the summer months.
+Added: However, it is too early to say with confidence whether this seasonality trend will continue in future periods.
+Added: Moreover, our future Jelmyto revenue will be impacted by various factors and we expect our Jelmyto revenue to fluctuate quarter-to-quarter for the foreseeable future.
+Added: UGN-102 (mitomycin) for intravesical solution
+Added: UGN-102 is our sustained-release formulation of mitomycin that we are developing for the treatment of low-grade intermediate risk NMIBC.
In October 2021, we reported final data from the Phase 2b OPTIMA II trial. The single-arm, open label trial completed enrollment of 63 patients at clinical sites across the United States and Israel in September 2019.
−Removed: Patients were treated with six weekly instillations of UGN-102 and underwent assessment of CR (the primary endpoint) four to six weeks following the last instillation. We initiated the Phase 3 ATLAS trial in December 2020 and until November 2021, were enrolling patients in this trial assessing UGN-102 with or without TURBT compared to standard of care (TURBT).
−Removed: In parallel, we continued to engage in discussions with the FDA and, based on this dialogue, we designed a trial in order to demonstrate the efficacy and safety of UGN-102.
−Removed: This new Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 as primary chemoablative therapy in patients with low-grade intermediate risk NMIBC.
−Removed: The design for the Phase 3 ENVISION trial is similar to our Phase 2 OPTIMA II trial in that the patient population will have similar clinical characteristics, receive the same treatment regimen and undergo the same efficacy and safety assessments and qualitative follow-up.
−Removed: Study participants will receive six once-weekly intravesical instillations of UGN-102.
−Removed: The planned primary endpoint will evaluate the complete response rate at three months after the first instillation, and the key secondary endpoint will evaluate durability over time in patients who achieve complete response at the three-month assessment.
−Removed: We initiated the Phase 3 ATLAS trial in December 2020 and until recently had been enrolling patients in this trial assessing UGN-102 with or without TURBT compared to standard of care.
−Removed: In parallel, we continued to engage in discussions with the FDA and, based on this dialogue, have designed an alternative trial in order to demonstrate the efficacy and safety of UGN-102.
−Removed: This new streamlined Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 as primary chemoablative therapy in patients with low-grade intermediate risk NMIBC.
−Removed: The design for this new Phase 3 ENVISION trial will be similar to our Phase 2 OPTIMA II trial in that the patient population will have the same clinical characteristics, receive the same treatment regimen and undergo the same efficacy and safety assessments and qualitative follow-up, but with different endpoints.
−Removed: Study participants will receive 6 once-weekly intravesical instillations of UGN-102.
−Removed: The planned primary endpoint is the complete response rate at three months after the first instillation, and the key secondary endpoint will be durability over time in patients who achieve complete response at the three-month assessment.
−Removed: In February 2022, we announced the initiation of the Phase 3 ENVISION trial, which is expected to enroll approximately 220 patients across 90 sites, with completion of enrollment expected by the end of 2022. Assuming positive findings, we anticipate submitting an NDA for UGN-102 in 2024.
−Removed: As a result of the FDA's acceptance of a single arm approach, we have stopped enrollment of the Phase 3 ATLAS study. However, at the time enrollment was stopped, any patients who had signed an informed consent were able to complete screening, and if eligible were randomized into the trial.
−Removed: Patients continue to be followed in Phase 3 ATLAS study, and clinical results from these patients are expected to generate additional safety data and other insights in our evaluation of UGN-102 as a primary therapy in the treatment of low-grade intermediate risk NMIBC.
−Removed: We have also initiated a Phase 3b study with the objective of demonstrating whether UGN-102 can be administered at home by a qualified home health professional, avoiding the need for repeated visits to a healthcare setting for instillation. Patients in the ongoing Phase 3b study will receive six once-weekly intravesical instillations of UGN-102.
−Removed: The Phase 3b study aims to enroll up to 10 patients across four centers.
−Removed: The initial treatment visit will occur at the investigative site and instillation will be performed by a qualified physician.
−Removed: Treatment visits two to six will take place at the patient's home and instillation will be performed by a properly trained and qualified home health professional.
−Removed: The primary endpoint of the study is the incidence of treatment-emergent adverse events (TEAEs), serious TEAEs, TEAEs of special interest, discontinuations from at home study treatment, and clinically significant abnormalities in laboratory tests (hematology, serum chemistry, and urinalysis).
−Removed: We believe the ease and convenience of home instillation has the potential to transform care and facilitate alternative access to treatment.
−Removed: Our immuno-uro-oncology pipeline includes UGN-301 (zalifrelimab), an anti-CTLA-4 antibody, which we intend to study as a combination therapy with multiple potential agents.
−Removed: UGN-301, an immune checkpoint inhibitor, is delivered using our proprietary 
−Removed: RTGel  technology , which has been designed to significantly improve the effectiveness of intravesical therapy.
−Removed: Our initial nonclinical studies involve the sequential use of UGN-201 (imiquimod), a TLR 7 agonist, and UGN-301 (zalifrelimab), an anti-CTLA-4 antibody, as an investigational treatment for high-grade NMIBC.
−Removed: Toll-like receptors are pattern recognition receptors whose importance in stimulating innate and adaptive immunity has been established by recent studies.
−Removed: Toll-like receptors are able to sense microbial components as well as host-derived endogenous molecules released by injured tissues and play a critical role in defending against invading pathogens.
−Removed: Imiquimod, in its topical formulation, is FDA approved for several indications, including superficial basal cell carcinoma.
+Added: Patients were treated with six weekly instillations of UGN-102 and underwent assessment of CR (the primary endpoint) four to six weeks following the last instillation; 65%, or 41 out of 63 patients, treated with UGN-102 achieved a complete response three months after the start of therapy.
+Added: In this subset of patients, 39 (95%), 30 (73%), and 25 (61%) remained disease-free at six, nine, and 12 months after treatment initiation, respectively.
+Added: The probability of durable response nine months after CR (12 months after treatment initiation) was estimated to be 72.5% by Kaplan-Meier analysis. Thirteen patients had documented recurrences.
+Added: Fifty-seven of 63 (90%) patients completed all six instillations of UGN-102 according to the study protocol.
+Added: Median duration of response was not reached.
+Added: The most common adverse events, greater than 10%, were most often reported as mild to moderate in severity and include dysuria, hematuria, urinary frequency, fatigue, urgency and urinary tract infection. The final data was published online in The Journal of Urology in October 2021 and was included in the January 2022 print edition.
+Added: In December 2022 we presented new data from the OPTIMA II study designed to obtain long-term follow-up data on UGN-102 that shows median duration of response of 24.4 months based on available data for 15 out of 25 patients. Seven patients remained in CR, six patients had recurrence of low-grade disease, one patient had progression to high-grade disease and one patient withdrew consent but remained in CR at the last evaluation prior to discontinuation.
+Added: All patients were alive at the last contact, and five patients were known to have had post-study treatment with transurethral resection of the bladder tumors or fulguration.
+Added: UGN-102 is administered locally using the standard practice of intravesical instillation directly into the bladder via a catheter.
+Added: The instillation into the bladder is expected to take place in a physician’s office as a non-operative same-day treatment, in comparison with TURBT or similar surgical procedures, which are operations conducted under general anesthesia and may require an overnight stay.
+Added: Surgical tumor removal often has limited success due to the inability to properly identify, reach and resect all tumors.
+Added: We believe that an effective chemoablation agent can potentially provide better eradication of tumors irrespective of the detectability and location of the tumors.
+Added: In addition, by removing the need for surgery, patients may avoid potential complications associated with surgery.
+Added: We initiated the Phase 3 ATLAS trial in December 2020 and until November 2021, were enrolling patients in this trial comparing UGN-102 with or without TURBT to standard of care, TURBT. In parallel, we continued to engage in discussions with the FDA and based on this dialogue, we designed a trial in order to demonstrate the efficacy and safety of UGN-102.
+Added: This Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 as primary chemoablative therapy in patients with low-grade intermediate risk NMIBC.
+Added: The design of the Phase 3 ENVISION trial is similar to our Phase 2 OPTIMA II trial in that the patient population has similar clinical characteristics, receives the same investigational treatment regimen and undergoes similar efficacy and safety assessments and qualitative follow-up.
+Added: Study participants receive six once-weekly intravesical instillations of UGN-102.
+Added: The primary endpoint will evaluate the complete response rate at three months after the first instillation, and the key secondary endpoint will evaluate durability of response in patients who achieve complete response at the three-month assessment.
+Added: In February 2022, we announced the initiation of the Phase 3 ENVISION trial, targeting enrollment of 220 patients across 90 sites.
+Added: In December 2022, we completed our target enrollment of the Phase 3 ENVISION trial. Assuming positive findings, we anticipate submitting an NDA for UGN-102 in 2024.
+Added: As a result of the FDA's acceptance of a single arm approach, we stopped enrollment of the Phase 3 ATLAS study. However, at the time enrollment was stopped, any patients who had signed an informed consent were able to complete screening, and if eligible were randomized into the trial.
+Added: Clinical results from these patients are expected to generate additional safety and efficacy data and other insights in our evaluation of UGN-102 as a primary therapy in the treatment of low-grade intermediate risk NMIBC.
+Added: We also initiated a Phase 3b study with the objective of demonstrating whether UGN-102 can be administered at home by a qualified home health professional, avoiding the need for repeated visits to a healthcare setting for instillation.
+Added: As per the study design, patients in this study received six once-weekly intravesical instillations of UGN-102 with the initial treatment visit occurring at the investigative site and instillation performed by a qualified physician.
+Added: Treatment visits two to six took place at the patient's home and instillation was performed by a properly trained and qualified home health professional.
+Added: The primary endpoints of the study include safety and tolerability, discontinuations from at home study treatment and feedback from patients, home health professionals and investigators via standardized questionnaires.
+Added: The study completed enrollment with a total of eight patients across four centers and all study visits for these enrolled patients have been completed.
+Added: Preliminary results were reported through a press release in February 2023, finding that UGN-102 was suitable to administer at home by a visiting nurse under the supervision of a treating physician and resulted in 75% of patients achieving a complete response, defined as no detectable disease three months after starting treatment.
+Added: Patients, nurses and investigators also completed home instillation feasibility questionnaires.
+Added: These standardized feasibility questionnaires highlighted that all eight patients preferred at-home to in-office treatment, and five of six patients recommended UGN-102 home instillation instead of TURBT.
+Added: Home instillation was reported as feasible for visiting nurses, and three of four investigators considered at-home treatment “not different”
+Added: than in-office treatment.
+Added: We believe establishing the precedent for a convenient at home solution may facilitate access to care and address quality of life issues that certain patients may face with the current standard of care.
+Added: UGN-301 
+Added: (zalifrelimab) intravesical solution
+Added: Our immuno-uro-oncology pipeline includes UGN-301, an anti-CTLA-4 monoclonal antibody, which we intend to study as a standalone agent and as a combination therapy with multiple potential agents.
+Added: Non-human primate toxicity studies supported the initiation of a multi-arm Phase 1 study of UGN-301 in combination with other agents.
+Added: We believe that this approach leverages our unique drug delivery technology and provides an opportunity to evaluate intravesical delivery of UGN-301 in combination with other immuno-modulators, chemotherapies, gene therapy and innate immune stimulators.
+Added: High-grade NMIBC is a highly aggressive form of bladder cancer.
+Added: TURBT followed by adjuvant intravesical immunotherapy with Bacillus of Calmette and Guerin ("BCG") is the current standard of care therapy for high-grade NMIBC. However, the high rates of recurrence and significant risk of progression to muscle-invasive tumors are particularly dangerous.
+Added: Radical cystectomy, or bladder removal is strongly advocated in patients with BCG-unresponsive NMIBC (i.e., patients with BCG-refractory and BCG-relapsing tumors in whom further BCG therapy is not recommended) or for patients who cannot tolerate BCG.
+Added: The first combination we are seeking to investigate clinically involves the sequential use of UGN-201 (imiquimod), a toll-like receptor-7 ("TLR 7") agonist, and UGN-301 in high-grade NMIBC ("high-grade NMIBC").
UGN-201 is a liquid formulation of imiquimod for intravesical administration that has been optimized for delivery in the urinary tract.
−Removed: UGN-201 does not use our RTGel technology. We believe that UGN-201 may elicit an adaptive immune response in the presence of released bladder cancer antigens, which may translate into a long lasting acquired immune response. 
+Added: We believe that UGN-201 may elicit an innate immune response in the presence of released bladder cancer antigens, which may translate into a long lasting acquired immune response.
+Added: We believe the combination of UGN-301 and UGN-201 could elicit an innate as well as adaptive immune response and potentially represent a valid post-TURBT adjuvant treatment of high-grade NMIBC. UGN-301 is delivered using our proprietary 
+Added: technology, which has been designed to significantly improve the effectiveness of certain intravesical therapy.
+Added: In November 2019, we entered into a worldwide license agreement with Agenus Inc.
+Added: to develop and commercialize zalifrelimab via intravesical delivery for the treatment of urinary tract cancers, initially in high-grade NMIBC.
+Added: We believe that the combination of UGN-301 and UGN-201 makes local therapy a potentially more effective treatment option while minimizing systemic exposure and potential side effects.
+Added: In March 2022, we announced FDA clearance of our Investigational New Drug application ("IND") to begin a novel Phase 1 clinical study of UGN-301 in patients with recurrent NMIBC. The novel study design utilizes a Master Protocol that we believe is a more efficient and streamlined approach to development.
+Added: It will provide more flexibility to add study arms as the trial progresses and is expected to increase efficiency and potentially reduce costs.
+Added: We expect the Master Protocol will allow us to more quickly evaluate safety, tolerability and dosing of UGN-301 in combination with additional immunomodulators and chemotherapies, with the goal of developing optimized treatment regimens for patients. The multi-arm Phase 1 study, which is expected to support the development of UGN-301 in high-grade NMIBC, was initiated in April 2022 and is actively enrolling.
