SAN DIEGO and SUZHOU, China, March 9, 2022 /PRNewswire/ — Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a company transforming the discovery and development of novel antibody-based therapies, today announced publication of four abstracts featuring preclinical data from its expanding pipeline in advance of the AACR Annual Meeting 2022 in New Orleans, Louisiana from April 8-13, 2022. The full abstracts are available on the AACR meeting website.

At AACR, presentations will include preclinical results showing the potential best-in-class profiles for three differentiated preclinical product candidates in IND-enabling studies: ADG138, ADG206 and ADG153. The fourth presentation introduces a new capability for the company’s proprietary bispecific T-cell engagers (TCEs) with CD28.

Details for the poster presentations include:

“These presentations highlight the promise of our AI-driven technology platform to build a deep, broad, and differentiated pipeline of transformative antibody therapeutics,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “Our ‘three-body’ technologies are well suited to discover and engineer antibody-based modalities against clinically important targets such as HER2, TROP2, B7H3, CD137, CD47 and CD28, overcoming challenges of prior platform technologies, validated by clinical data from our ongoing clinical programs, and endorsed by our strategic partnerships with global pharmaceutical and biopharmaceutical companies.”

Dr. Luo continued, “We are designing safe and effective antibody candidates across the cancer immunity cycle, including our POWERbody approach, which integrates the SAFEbody technology with multiple antibody-based modalities. These include ADG138, a new HER2xCD3 bispecific TCE for solid tumors, and ADG206, an Fc engineered anti-CD137 therapy, both designed for enhanced safety and efficacy. Additionally, we are establishing a new paradigm for CD28 TCEs by putting all the pieces together to ensure ultimate safety and mitigate known risks of this target – a unique, highly conserved epitope, our precision masking technology and a tumor antigen targeted TCE for local activation. With these novel therapeutic approaches, we aim to push the boundaries of what is possible with TCEs – to achieve safe, potent and durable responses for solid tumors.”
