"The maturing data from the Phase 1 dose escalation study evaluating masofaniten in combination with enzalutamide continue to demonstrate that the combination is well tolerated, accompanied by deep and durable reductions in circulating prostate-specific antigen ("PSA") levels. While the data are still immature, the durability of the PSA responses is encouraging with a median time to PSA progression currently at 16.6 months. The Phase 2 dose expansion head-to-head portion of the study is underway and is designed to evaluate the proportion of patients with a PSA decline on combination therapy compared to single agent enzalutamide," said David Parkinson, MD, President and CEO of ESSA. "We look forward to evaluating the potential long-term benefits of masofaniten in patients with metastatic castration-resistant prostate cancer ("mCRPC") and to providing future updates."

Title: Phase 1/2 trial of oral EPI-7386 (masofaniten) in combination with enzalutamide (Enz) compared to Enz alone in patients with metastatic castration-resistant prostate cancer (mCRPC): Phase 1 (P1) results and phase 2 (P2) design.
Presenting Author: Christos Kyriakopoulos, MD, University of Wisconsin-Madison Carbone Cancer Center
Abstract #: 141
Date and time: Thursday, January 25, 2024; 11:30-1:00 p.m. PT

Data summary: This Phase 1/2 multicenter, open-label clinical trial enrolled patients with mCRPC who have received androgen deprivation therapy and who are naïve to second-generation antiandrogens but may have been treated previously with one line of prior chemotherapy in the metastatic hormone-sensitive prostate cancer setting. The data presented today include 18 patients across four cohorts in the Phase 1 dose escalation portion of the study. Masofaniten has no effect on enzalutamide exposure, thus allowing the use of full dose per label (160mg) of enzalutamide in combination. Enzalutamide reduces masofaniten exposure but twice daily dosing of masofaniten appears to mitigate the reduction and maintains clinically relevant drug exposures.

In patients evaluable for safety (n=18), masofaniten combined with enzalutamide, continues to be well-tolerated at the dose levels tested through 25 cycles of dosing in some patients. Most frequent adverse events were Grades 1 and 2, related to either AR inhibition or gastrointestinal tract irritation. In Cohort 4, one patient experienced a Grade 3 rash, which was observed immediately following administration of masofaniten combined with enzalutamide and deemed probably related, resulting in the expansion of the cohort from four to seven patients. No additional dose-limiting toxicities (DLTs) were observed, therefore the maximum tolerated dose (MTD) was not reached. The recommended Phase 2 combination doses (RP2CDs) were identified as masofaniten 600 mg twice daily (BID) in combination with enzalutamide 160 mg once daily (QD).

In the patients evaluable for efficacy (n=16), rapid, deep and durable reductions in PSA were observed, regardless of previous chemotherapy status, including in patients who received lower than the full dose of enzalutamide (120 mg). Across all dose cohorts, 88% of patients (14 of 16) achieved PSA50, 81% of patients (13 of 16) achieved PSA90, 69% of patients (11 of 16) achieved PSA90 in less than 90 days, and 63% of patients (10 of 16) achieved PSA <0.2ng/mL. While the data for disease PSA progression are still maturing with a current median follow up of 11.1 months, the median time to PSA progression is at 16.6 months.

The randomized, open-label, two arm, Phase 2 dose expansion portion of the study is underway and is designed to evaluate the combination of masofaniten and enzalutamide versus single agent enzalutamide in patients with mCRPC naïve to second generation anti-androgens. The study is currently enrolling at approximately 25 sites in the USA, Canada and Australia. Expansion to European sites is in progress.

About Masofaniten
Masofaniten (formerly known as EPI-7386) is a first-in-class investigational, highly selective, oral, small molecule inhibitor of the N-terminal domain ("NTD") of the androgen receptor ("AR"). Masofaniten’s unique mechanism of action disrupts the AR signaling pathway, the primary pathway that drives prostate cancer growth, by selectively binding to the NTD, a region of the AR that is not currently targeted by other therapies. Masofaniten is currently being studied in an open-label, randomized Phase 2 clinical trial (NCT05075577) in combination with enzalutamide in patients with metastatic castration-resistant prostate cancer (mCRPC) naïve to second-generation antiandrogens. ESSA is also conducting a Phase 1 monotherapy study (NCT04421222) in patients with mCRPC whose tumors have progressed on standard-of-care therapies. The U.S. Food and Drug Administration has granted Fast Track designation to masofaniten for the treatment of adult male patients with mCRPC resistant to standard-of-care treatment. ESSA retains all rights to masofaniten worldwide.

Under the terms of the agreement, GSSA will receive from Jiangsu Alphamab and 3D Medicines, an exclusive license to develop, register, commercialize, Envafolimab for the oncology indication in the Territory. Jiangsu Alphamab will be the exclusive supplier of the product. 3D Medicines retains the right to develop and commercialize Envafolimab for any purpose outside the Territory. The Licensors will receive a low double digit Million US Dollar amount up to launch, additional triple digit Million US Dollar milestone payments based on sales performance across the length of the agreement, and a royalty fee of single-to-double-digits percentage according to the level of net sales. The Licensors’ respective entitlement to the payments (including the upfront payment, milestone payment and the royalty fees) under the License Agreement are subject to the agreements between 3D Medicines and Jiangsu Alphamab.

"This is an important milestone for Glenmark, as through this transformational deal, we gain access to the first recombinant humanized single domain antibody against PD-L1 in a subcutaneous formulation for a wide territory globally. We are excited at the opportunity to take this innovative immuno-oncology product to cancer patients across the emerging markets and meaningfully contribute towards improving their access to potentially life-saving treatments," remarked Glenn Saldanha, Chairman & Managing Director, Glenmark Pharmaceuticals Ltd.

Envafolimab, under the brand name ENWEIDA (恩維達) has been approved in China by the National Medical Products Administration (Chinese NMPA) in November 2021 as the global-first subcutaneous injection PD-L1 inhibitor for the treatment of adult patients with previously treated microsatellite instability-high (MSI-H) or deficient MisMatch repair (dMMR) advanced solid tumor. Over 30,000 patients in China have already greatly benefited from this innovative treatment where, in December 2023, it has also been officially included in the ‘List of Breakthrough Therapies’ by the NMPA*.

Overall, dMMR prevalence across 13 tumor types (based on 54 papers and 20,383 patients) was estimated at 16% (11%–22%)**, which makes it quite a widespread genetic signature among cancer patients. Envafolimab has the potential to provide an effective treatment for this population across Emerging Markets and beyond.

Furthermore, Envafolimab is currently being developed in the USA by Tracon Pharma in a pivotal trial in soft tissue sarcoma (STS) subtypes including, Undifferentiated Pleomorphic Sarcoma (UPS) and the genetically related myxofibrosarcoma (MFS). Envafolimab has obtained two orphan drug designation from the U.S. FDA for advanced biliary tract cancer and soft tissue sarcoma (STS), and a Fast Track designation for STS. Additional indications such as biliary tract cancer and non-small cell lung cancer are currently in development.
