In 2025, muzastotug showed 29% confirmed overall response rate (ORR) among 21 patients with MSS CRC in the 20 mg/kg dose cohorts Median overall survival (OS) for the 10 mg/kg cohorts was 19.4 months, with a median follow-up of 17.8 months 4% overall discontinuation rate, no dose limiting toxicities, and no Grade 4 or 5 treatment-related adverse events (TRAEs) across 67 patients in all dose cohorts supports improved tolerability profile of muzastotug Randomized Phase 2 trial enrollment ahead of plan, with potential updates in 2026 and results expected in 1H 2027; registration trial expected to begin once optimal dose regimen has been established Cash and cash equivalents of $74.5 million as of December 31, 2025, plus proceeds raised from the ATM Offering in 2026 year-to-date, anticipated to provide cash runway into early 2028 SAN DIEGO, Calif. and SUZHOU, China, April 01, 2026 (GLOBE NEWSWIRE) -- Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biotechnology company transforming the discovery and development of novel anti-body-based therapies, today reported financial results for the full year 2025 and provided corporate updates. “Our clinical data for muzastotug plus pembrolizumab consistently demonstrate potent, dose-dependent efficacy,” said Peter Luo, Ph.D., Chairman and President of R&D at Adagene. “The 10 mg/kg data reported at ASCO have now matured into the classic long survival tail of CTLA-4 inhibition. By significantly mitigating severe toxicities, patients remain on therapy longer, allowing CTLA-4-mediated intratumoral Treg depletion, alongside PD-1-mediated reinvigoration and CTLA-4-mediated priming of effector T cells, to drive durable disease control. Importantly, these data provide a clear, de-risked read-through to the 20 mg/kg dose, which already shows an encouraging 29% ORR with median duration of response not yet reached. “Supported by Fast Track Designation and FDA alignment under Project Optimus, we are on track to finalize the optimal combination dose regimen for a potential MSS colorectal cancer registrational trial. The expanded therapeutic window also helps to establish muzastotug as a foundational combination backbone. At AACR, we will showcase this potential with data from triplet regimens—combining with fruquintinib in 3L+ MSS CRC, alongside results from the Morpheus Liver study evaluating a triplet of muz...

Muzastotug (ADG126) Phase 1b/2 in MSS CRC shows 19.4-month median OS (mOS) in 10 mg/kg dose cohorts; mOS for 20 mg/kg cohorts has not yet been reached Alignment with FDA on Phase 2 and Phase 3 trial design elements. Company expects to begin enrolling patients in Phase 2 in 2H 2025 SAFEbody option exercised and up to US$25 million strategic investment by Sanofi, with cash runway extended into 2027 Sanofi will conduct a Phase 1b/2 trial in combination with ADG126 in over 100 patients Strengthened leadership team with key additions Partnered with ConjugateBio for development of bispecific ADCs SAN DIEGO and SUZHOU, China, Aug. 12, 2025 (GLOBE NEWSWIRE) -- Adagene Inc. (“Adagene” or the “Company”) (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, 2025, and provided corporate updates. “The first half of 2025 was tremendously important for Adagene, as we shared the early overall survival benefit with ADG126 in combination with Merck’s (known as MSD outside of the US and Canada) anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) that exceeds standard of care and is highly competitive with data from other products in development. The safety and tolerability data from ADG126 in combination with pembrolizumab in our Phase 1b/2 study in microsatellite stable colorectal cancer contributes to a large body of growing evidence that the power of CTLA-4 inhibition can be harnessed more safely with our approach utilizing conditional activation in the tumor microenvironment. Grade 3 treatment-related adverse events were less than 20%, which is an outstanding achievement given that ADG126 was dosed 10 to 20 times higher than the approved CTLA-4 inhibitors, in order to drive dose-dependent depletion of regulatory T-cells at the desired level inside tumors,” said Peter Luo, Ph.D., Chairman, CEO and President of R&D at Adagene. “Now that we have aligned with the FDA on Phase 2 and Phase 3 design elements, which do not require an ADG126 monotherapy arm, we have a clear line of sight into what will be required for regulatory approval. We look forward to initiating the Phase 2 study later this year.” PIPELINE HIGHLIGHTS ADG126 - Phase 1b/2 data and regulatory update: As presented at the 2025 American Society of Clinical Oncol...

Muzastotug Phase 2 dose expansion in MSS CRC with a 20 mg/kg loading dose regimen shows 33% overall response rate with four confirmed partial responses SAFEbody technology utilized to create masked T cell engagers for potentially superior safety profile with enhanced therapeutic index Cash balance of $85.2 million provides runway into late 2026 SAN DIEGO and SUZHOU, China, March 24, 2025 (GLOBE NEWSWIRE) -- Adagene Inc. (“Adagene”) (Nasdaq: ADAG), a platform-driven, clinical-stage biotechnology company transforming the discovery and development of novel anti-body-based therapies, today reported financial results for the full year 2024 and provided corporate updates. “The clinical data we generated in 2024 with ADG126 gives us great confidence in our ability to provide patients with colorectal cancer a tolerable, efficacious treatment option. These data also provide the basis for us to expand our study in microsatellite stable colorectal cancer (MSS CRC) to include earlier lines of therapy and patients with liver metastases, a patient subpopulation that has historically seen little to no benefit from checkpoint inhibitors,” said Peter Luo, Ph.D., Chairman, CEO and President of R&D at Adagene. “Regulatory T cells, a primary mechanism of resistance, can be overcome through higher and more frequent dosing of a conditionally active anti-CTLA-4 antibody. We continue to believe that anti-CTLA-4 therapy can transform immunotherapy in combination with anti-PD-1 and other therapies. Our SAFEbody masking capability enables the best therapeutic index among all CTLA-4 programs, showing the potential to unlock therapeutic value with a target previously limited by safety concerns.” Dr. Luo continued, “In addition to ADG126, we have also utilized our SAFEbody masking technology to create T cell engagers (TCEs) that can link T cells to any number of antigens presented on tumor cells. These masked TCEs can recruit the immune system for conditional cytotoxicity, shrinking tumors and prolonging patient survival. The combination of TCEs with ADG126, which depletes CTLA-4 mediated regulatory T cells, is expected to enhance the response to TCE therapy. We look forward to sharing more on our TCE programs going forward.” PIPELINE HIGHLIGHTS ADG126 - Phase 1b/2 data: 20 mg/kg loading dose followed by 10 mg/kg Q3W in combination with pembrolizumab, Merck’s (known as MSD outside of the...
