Shares in Gilead Sciences were down 11% on Monday after the company reported that its Trop-2-directed antibody-drug conjugate Trodelvy (sacituzumab govitecan-hziy) missed the primary endpoint in a Phase III trial of patients with metastatic non-small-cell lung cancer (NSCLC). The EVOKE-01 study compared Trodelvy to docetaxel in 603 patients with advanced or metastatic NSCLC that progressed after platinum-based chemotherapy and checkpoint inhibitor treatment. While Trodelvy showed a numerical improvement on the primary endpoint of overall survival (OS) for both squamous and non-squamous NSCLC, the difference was not statistically significant.However, a subgroup analysis showed Trodelvy improved median OS by over 3 months compared to chemotherapy in patients who did not respond to their last PD-(L)1 inhibitor therapy. This subgroup accounted for over 60% of trial participants, and Gildead plans to do further analyses to better understand the role Trodelvy may have played.Meanwhile, the company says it didn't see this "magnitude of difference" in patients who responded to their last anti-PD-(L)1 therapy. Although pre-specified in the study protocol, the analysis was not subjected to formal statistical testing for alpha control."The totality of our data gives us continued confidence in Trodelvy's potential in metastatic NSCLC, and in our broader lung cancer clinical development programme," said chief medical officer Merdad Parsey.Gilead is also conducting Phase II and III trials of Trodelvy in combination with Merck & Co.'s Keytruda (pembrolizumab) as an initial treatment for NSCLC patients, although Parsey indicated that Phrase III testing in the front-line setting is enrolling, but will not be available for "a couple of years at least."

Objective Response Rate by investigator review increased to 15% since interim analysis in September Full ENVASARC enrollment expected in 1Q 2024 and final data anticipated during 3Q 2024 SAN DIEGO, Dec. 20, 2023 (GLOBE NEWSWIRE) -- TRACON Pharmaceuticals (NASDAQ: TCON), a clinical stage biopharmaceutical company utilizing a cost-efficient, CRO-independent product development platform to advance its pipeline of novel targeted cancer therapeutics and to partner with other life science companies, today announced that the ongoing pivotal Phase 2 ENVASARC trial has enrolled more than 70 of the 80 planned patients in Cohort C of single agent envafolimab treatment at a dose of 600 mg subQ every three weeks. Additional safety and efficacy data were reviewed for 46 patients enrolled into cohort C who were the subject of the September independent data monitoring committee (IDMC) review. At that time, patients had completed a minimum of 12 weeks of efficacy evaluations and the objective response rate (ORR) was 13% by investigator review and 8.7% by blinded independent central review (BICR). Since then, an additional patient has achieved an objective response by investigator review, which increased the ORR by investigator review to 15%. The most recent objective response has not yet been confirmed by BICR and the patient remains on treatment. Median duration of response by BICR remains greater than six months. In addition, envafolimab remains well tolerated and grade > 3 related toxicity has not been reported to date. “We continue to believe that these data position envafolimab to become a potentially compelling treatment option for patients with the refractory sarcoma subtypes of UPS and MFS based on the ORR and tolerability data to date,” said Charles Theuer, M.D., Ph.D., TRACON’s Chief Executive Officer. “ENVASARC enrollment continues to be brisk, reflecting the high unmet need that exists for these patients.” Updated safety and efficacy data are expected in 1Q 2024, including in the more than 20 patients enrolled following the September IDMC review who will have had a minimum of 12 weeks of efficacy evaluations (two CT scans) at that time. The primary endpoint of the ENVASARC study is achievement of an ORR in nine of 80 patients (11.25%) treated with envafolimab by BICR and median duration of response of greater than six months is a key secondary endpoint. About Envafolimab Envafolimab (KN035), a single-domain antibody against PD-L1 invented by Alphamab Oncology and licensed by TRACON, is the first approved subcutaneously injected PD-(L)1 inhibitor. Envafolimab was approved by the Chinese NMPA in November 2021 in adult patients with MSI-H/dMMR advanced solid tumors who failed systemic treatment and have no satisfactory alternative treatment options. In December 2019, Alphamab Oncology, 3D Medicines and TRACON entered into a collaboration whereby TRACON has the right to develop and commercialize envafolimab in soft tissue sarcoma in North America. Envafolimab is currently being studied in the ENVASARC Phase 2 pivotal trial in the United States sponsored by TRACON and a Phase 3 pivotal trial in combination with gemcitabine and oxaliplatin in advanced biliary tract cancer patients in China sponsored by TRACON’s corporate partners, Alphamab Oncology and 3D Medicines. TRACON has received orphan drug designation from the U.S. Food and Drug Administration (FDA) for envafolimab for patients with soft tissue sarcoma and fast track designation from the FDA for envafolimab for patients with locally advanced, unresectable or metastatic undifferentiated pleomorphic sarcoma (UPS) and myxofibrosarcoma (MFS) who have progressed on one or two prior lines of chemotherapy. About ENVASARC (NCT04480502) The ENVASARC Phase 2 pivotal trial is a multicenter, open label, randomized, non-comparative, parallel cohort study at 30 top cancer centers in the United States and the United Kingdom that began dosing in December 2020. ENVASARC is enrolling patients with UPS or MFS who have progressed following one or two lines of prior treatment and have not received an immune checkpoint inhibitor. In Cohort C, a total of 80 patients will receive treatment with single agent envafolimab at 600 mg every three weeks. The primary endpoint is objective response rate by central review with duration of response a key secondary endpoint. About TRACON TRACON is a clinical-stage biopharmaceutical company utilizing a cost-efficient, CRO-independent, product development platform to advance its pipeline of novel targeted cancer therapeutics and to partner with other life science companies. The Company’s clinical-stage pipeline includes: Envafolimab, a PD-L1 single-domain antibody given by rapid subcutaneous injection that is being studied in the pivotal ENVASARC trial for sarcoma; YH001, a potential best-in-class CTLA-4 antibody in Phase 1 development; and TRC102, a Phase 2 small molecule drug candidate for the treatment of lung cancer. TRACON is actively seeking additional corporate partnerships through a profit-share or revenue-share partnership, or through franchising TRACON’s product development platform. TRACON believes it can serve as a solution for companies without clinical and commercial capabilities in the United States or who wish to become CRO-independent.
