ADG116-P001 trial being initiated at multiple sites with dosing to begin early 2022

SAN DIEGO, CA, USA and SUZHOU, China I November 29, 2021 I Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biopharmaceutical company committed to transforming the discovery and development of novel antibody-based immunotherapies, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application to proceed with a Phase 1b/2 clinical trial of its anti-CTLA-4 monoclonal antibody (mAb), ADG116, in combination with the anti-PD-1 antibody, pembrolizumab. The global trial (ADG116-P001 / KEYNOTE-C97) will evaluate patients with advanced/metastatic solid tumors at multiple sites in the U.S. and Asia Pacific (APAC).

ADG116 utilizes Adagene’s proprietary NEObody™ platform technology and is designed to target a unique conserved epitope of CTLA-4 with enhanced efficacy by potent Treg depletion in the tumor microenvironment (TME). ADG116 is designed with a soft ligand blocking to address safety concerns associated with existing CTLA-4 therapeutics.

“The FDA clearance of this trial represents a significant milestone for our anti-CTLA-4 program as we advance our evaluation of ADG116 in combination with anti-PD-1 therapy,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “By applying NEObody technology, ADG116 can overcome existing safety limitations of anti-CTLA-4 therapies to achieve improved clinical benefit. Our exploration of ADG116 with pembrolizumab aims to unleash the dual CTLA-4/PD-1 blockade and realize the full potential of this combination therapy approach as a cornerstone of cancer treatment – balancing safety and efficacy.”

The ADG116-P001 trial is expected to dose the first patient in early 2022, and is designed to evaluate the safety and tolerability, determine the maximum tolerated dose, and assess preliminary efficacy of the combination of ADG116 and pembrolizumab.

Additionally, the ongoing ADG116-1003 trial is on track to expand with two combination cohorts investigating safety and preliminary efficacy of ADG116 with either toripalimab or ADG106 in patients with advanced/metastatic solid tumors.
