Phase 1 Data Published in ASCO Proceedings Determined the Recommended Phase 2 Dose
Additional Cohort of Patients with a Specific Androgen Receptor Point Mutation Added to Ongoing Phase 2 Study
Phase 2 Data Expected in 2nd half 2020; Potential for $45 Million Opt-in Payment from Janssen
SAN DIEGO, July 02, 2019 (GLOBE NEWSWIRE) -- TRACON Pharmaceuticals (NASDAQ:TCON), a clinical stage biopharmaceutical company focused on the development and commercialization of novel targeted therapeutics for cancer, wet age-related macular degeneration through our license to Santen Pharmaceutical Co. Ltd., and utilizing our product development platform to partner with ex-U.S. companies to develop and commercialize innovative products in the U.S., today provided an update on its TRC253 program for the treatment of metastatic castrate resistant prostate cancer, which was licensed from Janssen Pharmaceutica N.V. in 2016.
Phase 1 data from the ongoing Phase 1/2 clinical trial published in the 2019 ASCO Proceedings
Phase 2 portion of the ongoing Phase 1/2 trial amended to add an additional cohort of patients
“We are pleased to have successfully completed the Phase 1 portion of the first-in-human study of TRC253 and look forward to the availability of Phase 2 data, which we expect in the second half of 2020,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “Following delivery of the Phase 2 data, Janssen will have the right to reacquire the TRC253 program in return for an opt-in fee of $45 million and further success-based milestone and royalty payments.”
About TRC253 (formerly JNJ-63576253)
TRC253 is a novel, orally bioavailable small molecule discovered and developed by Janssen that is a potent, high affinity competitive inhibitor of the AR. TRC253 is also a pan-inhibitor of multiple AR mutations, including the F877L mutation, and is under development for the treatment of men with prostate cancer in a Phase 1/2 clinical trial (NCT02987829). The AR F877L mutation results in an alteration in the ligand binding domain that confers resistance to current AR inhibitors.
Activation of the AR is crucial for the growth of prostate cancer at all stages of the disease. Therapies targeting the AR have demonstrated clinical efficacy by extending time to disease progression, and in some cases, the survival of patients with metastatic castration-resistant prostate cancer. However, resistance to these agents is often observed and several molecular mechanisms of resistance have been identified, including amplification, overexpression or mutation of the AR.
TRC253 is intended to address resistance mechanisms to current AR inhibitors by specifically targeting mutations in the AR ligand binding domain. TRC253 also potently inhibits signalling through the wild type AR. These susceptible AR mutations have been identified using circulating tumor DNA assays, potentially allowing for selected patient biomarker-directed therapy.
Following completion of the initial Phase 1/2 clinical trial, Janssen will have an exclusive option to reacquire full rights to TRC253 for an upfront payment of $45 million to TRACON, and obligations to pay regulatory and commercialization milestones totaling up to $137.5 million upon achievement of specified events and a low single-digit royalty. If Janssen does not exercise its exclusive option to reacquire the program, TRACON would then retain worldwide development and commercialization rights to the program and would be obligated to pay Janssen a total of up to $45 million in development and regulatory milestones upon achievement of specified events, in addition to a low single digit royalty.
TRACON develops targeted therapies for cancer and ophthalmic diseases. The Company’s clinical-stage pipeline includes: DE-122, the ophthalmic formulation of carotuximab being developed in wet AMD through a license to Santen Pharmaceutical Company Ltd.; TRC102, a small molecule being developed for the treatment of lung cancer and glioblastoma; TRC253, a small molecule being developed for the treatment of prostate cancer; and TJ004309, a CD73 antibody being developed for the treatment of advanced solid tumors. TRACON is actively seeking additional corporate partnerships whereby it shares in the cost and risk of clinical development and commercialization of innovative product candidates. In these partnerships TRACON believes it can serve as a solution for companies without clinical and commercial capabilities in the United States.
