ADAGENE REPORTS FINANCIAL RESULTS FOR THE SIX MONTHS ENDED JUNE 30, 2022 AND PROVIDES CORPORATE UPDATES

– Topline data for anti-CTLA-4 antibody, ADG116, shows compelling clinical safety and complete and partial responses as both a single agent and in combination with anti-PD-1 therapy; results to be presented at SITC 2022 –

– Masked, anti-CTLA-4 antibody, ADG126, safely dosed repeatedly up to 20 mg/kg as a single agent with encouraging efficacy signals; results to be presented at ESMO 2022 –

– Presentation of combination dosing data with anti-PD-1 therapies in 2022, while dose expansion begins for both ADG116 and ADG126 in targeted tumors –

– Submitted regulatory filing for clinical trial of masked, IgG1-based anti-CD137 candidate, ADG206, with greater preclinical potency than the analog of a benchmark antibody, urelumab, that demonstrated monotherapy efficacy in clinic; patient dosing planned in early 2023 –

– Cash balance of US$168 million supports streamlined operations into late 2024, with planned key readouts in 2023 for anti-CTLA-4 and anti-PD-1 combination therapies expected to pave way for pivotal trials –

SAN DIEGO and SUZHOU, China, Sept 5 (Bernama-GLOBE NEWSWIRE) -- Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biotechnology company transforming the discovery and development of novel antibody-based therapies, today reported financial results for the six months ended June 30, 2022 and provided corporate updates.

“We are prioritizing development of two anti-CTLA-4 antibodies, which have best-in-class profiles and are on track to deliver proof-of-concept clinical results in combination therapy in 2023. Anti-CTLA-4 therapy is known for dose dependent toxicity, making it extremely difficult to optimize dosing levels, dosing frequency and dosing intervals for prevailing anti-CTLA-4 therapy, especially in combination therapy with anti-PD-1. We have solved this problem with differentiated candidates suitable for the massive market opportunity for next generation anti-CTLA-4 therapies, increasing market penetration into known and new indications with enhanced safety and efficacy, especially for tumor types not addressed with the currently available therapy, and rapid entry into new markets such as China with few approved indications for anti-CTLA-4 in combination with widely accessible anti-PD-1 therapy,” said Peter Luo, Ph.D., Co-founder, Chief Executive Officer and Chairman of Adagene. “We are also excited to advance our next generation anti-CD137 agonistic antibody, ADG206, into clinic given its first- and best-in-class potential in both monotherapy and in combination with multiple agents.”
