The companies have entered into a global exclusive license agreement for CMG901, a potential first-in-class antibody drug conjugate (ADC) targeting Claudin 18.2, a promising therapeutic target in gastric cancer.

Under the licence agreement, AstraZeneca will be responsible for the research, development, manufacture and commercialisation of CMG901 globally.

CMG901

CMG901 is currently being evaluated in a Phase I clinical trial for the treatment of Claudin 18.2-positive solid tumours, including gastric cancer. Preliminary results from the Phase I trial have shown an encouraging clinical profile for CMG901, with early signs of anti-tumour activity across the dose levels tested.

“We are excited by the opportunity to accelerate the development of CMG901, a potential new medicine for patients with Claudin18.2-expressing cancers. CMG901 strengthens our growing pipeline of antibody drug conjugates and supports our ambition to expand treatment options and transform outcomes for patients with gastrointestinal cancers,” says Puja Sapra, Senior Vice President, Biologics Engineering & Oncology Targeted Delivery, Oncology R&D, AstraZeneca.
