Adagene Announces First Patients with Advanced Non-Small Cell Lung Cancer Dosed in Phase 1b/2 Clinical Trial of ADG106 in Combination with Nivolumab in Singapore

Clinical trial to be conducted at the National University Cancer Institute, Singapore and the National Cancer Centre Singapore, in Collaboration with the Singapore Translational Cancer Consortium

SAN DIEGO and SUZHOU, China, Jan. 13, 2022 (GLOBE NEWSWIRE) — Adagene Inc. (“Adagene”) (Nasdaq: ADAG) today announced that the first patients have been dosed in a phase 1b/2 clinical trial of the anti-CD137 agonist antibody, ADG106, in combination with the anti-PD-1 antibody, Nivolumab for patients with advanced non-small cell lung cancer (NSCLC) who have progressed on prior therapies.

The phase 1b/2 open label trial is designed to evaluate safety, tolerability, and anti-tumor activity of the combination in up to 53 patients with advanced NSCLC who have progressed after prior treatment. The trial will also include exploratory biomarker analyses of a novel predictive biomarker and immune cell profiling in response to the treatment.

“This clinical trial is a key step in development of ADG106, which is being evaluated in combination with multiple anti-PD-1 therapies for synergistic T-cell stimulation that was shown in both preclinical and clinical studies in comparison with anti-CD137 monotherapy. With the combination of these two independent, complementary pathways, ADG106 has the potential to overcome resistance to anti-PD-1 therapy, which remains a major limitation in the treatment of metastatic NSCLC,” said Peter Luo, Ph.D., Co-Founder, Chief Executive Officer and Chairman of the Board of Adagene. “The trial also applies a convenient flat dosing regimen presenting long-term development opportunities for ADG106. We are excited about the potential of ADG106 combinations to improve patient lives for this important indication, where exploratory biomarkers related to ADG106 are involved.”

The clinical trial is being led by Professor Goh Boon Cher, Senior Consultant, Department of Hematology-Oncology and Deputy Director (Research) at NCIS, and Associate Professor Daniel Tan, Head of the Division of Clinical Trials and Epidemiological Sciences and Senior Consultant, Division of Medical Oncology, NCCS. Both Professor Goh and Associate Professor Tan lead the STCC’s Cancer Clinical Trials & Investigational Medicine Unit that brings together centers in Singapore for scaled up capacity, efficiency and expertise in conducting cancer clinical trials.

NSCLC is the leading cause of cancer-related deaths worldwide. Despite the proven use of low-dose CT scan as a screening tool for lung cancer, most patients still present with stage 3 or 4 disease and only about 20 percent are operable, with a five-year survival overall of about 10 percent^[1]. Metastatic disease is the primary cause of death from NSCLC.

About ADG106
ADG106, is a fully human ligand-blocking, agonistic anti-CD137 IgG4 mAb being developed for the treatment of advanced solid tumors and non-Hodgkin’s lymphoma. CD137 stimulates the immune system to attack cancer cells and is a key driver for long-lasting T-cell proliferation and survival. Clinical trials of ADG106 as monotherapy have been conducted in the U.S. and China. A trial in combination with toripalimab is underway in China, and one in combination with pembrolizumab is planned.

About Nivolumab
Nivolumab, marketed globally as Opdivo, is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Nivolumab has become an important treatment option across multiple cancers, including advanced NSCLC.
