Adagene announces up to $25 million strategic investment from Sanofi

July 01, 2025 07:00 ET | Source: Adagene Inc. - Sanofi to exercise option on third SAFEbody discovery program and sponsor combination clinical trial with muzastotug - Company expects proceeds to extend cash runway into 2027 SAN DIEGO and SUZHOU, China, July 01, 2025 (GLOBE NEWSWIRE) -- Adagene Inc. (“Adagene or the Company”) (Nasdaq: ADAG), a company transforming the discovery and development of novel antibody-based therapies, today announced strategic investment and option exercise by Sanofi (Euronext: SAN FP). Sanofi has agreed to make strategic investment of up to US$25 million in Adagene. The Company plans to use the proceeds to fund its research and development activities, including clinical development of muzastotug (ADG126), an anti-CTLA-4 SAFEbody, through a randomized phase 2 trial in microsatellite stable colorectal cancer (MSS CRC). To further explore the clinical potential of muzastotug, Adagene will supply Sanofi with muzastotug to evaluate the safety, efficacy, pharmacokinetics and biomarker data in combination with other anticancer therapies in over 100 patients in a phase 1/2 clinical trial in advanced solid tumors. Adagene continues to own worldwide commercial rights to muzastotug. Sanofi has also exercised its option to select a third SAFEbody discovery program, utilizing Adagene’s proprietary masking technology and antibody engineering expertise. The bispecific therapeutic, with undisclosed targets, will be engineered by Adagene and induces an option exercise fee, as well as milestones and royalties as per the 2022 partnership agreement with Adagene. “Expanding our partnership with Sanofi highlights the potential of our SAFEbody platform and the clinical proof of concept for ADG126, our masked anti-CTLA-4 program and the most advanced of its kind,” said Peter Luo, Chairman, CEO and President of R&D at Adagene. “This strategic partnership reinforces our shared vision of ADG126’s promise in advanced solid tumors, including MSS CRC, where dose-limiting challenges have hindered anti-CTLA-4 therapies. We value our trusted relationship with Sanofi.” As of December 31, 2024, the Company had audited cash and cash equivalents of US$85.2 million. The proceeds from the investment of Sanofi, together with the current cash and cash equivalents, are expected to be sufficient to fund planned operations into 2027. Following the equity investment and strategic collaborations, a Sanofi representative will join Adagene’s Scientific Advisory Board (SAB), which provides strategic advice on the scientific and clinical aspects of the Company’s activities. About Adagene Adagene Inc. (Nasdaq: ADAG) is a platform-driven, clinical-stage biotechnology company committed to transforming the discovery and development of novel antibody-based cancer immunotherapies. Adagene combines computational biology and artificial intelligence to design novel antibodies that address globally unmet patient needs. The company has forged strategic collaborations with reputable global partners that leverage its SAFEbody® precision masking technology in multiple approaches at the vanguard of science. Powered by its proprietary Dynamic Precision Library (DPL) platform, composed of NEObody™, SAFEbody, and POWERbody™ technologies, Adagene’s highly differentiated pipeline features novel immunotherapy programs. The company’s SAFEbody technology is designed to address safety and tolerability challenges associated with many antibody therapeutics by using precision masking technology to shield the binding domain of the biologic therapy. Through activation in the tumor microenvironment, this allows for tumor-specific targeting of antibodies in tumor microenvironment, while minimizing on-target off-tumor toxicity in healthy tissues. Adagene’s lead clinical program, ADG126 (muzastotug), is a masked, anti-CTLA-4 SAFEbody that targets a unique epitope of CTLA-4 in regulatory T cells (Tregs) in the tumor microenvironment. ADG126 is currently in phase 1b/2 clinical studies in combination with anti-PD-1 therapy, particularly focused on Metastatic Microsatellite-stable (MSS) Colorectal Cancer (CRC). Validated by ongoing clinical research, the SAFEbody platform can be applied to a wide variety of antibody-based therapeutic modalities, including Fc empowered antibodies, antibody-drug conjugates, and bi/multi-specific T-cell engagers.
