LONDON, UK: AstraZeneca‘s Alexion has exercised its option to acquire all remaining equity in Caelum Biosciences for CAEL-101, a potentially first-in-class fibril-reactive monoclonal antibody (mAb) for the treatment of light chain (AL) amyloidosis.

AL amyloidosis is a rare disease in which misfolded amyloid proteins build up in organs throughout the body, including the heart and kidneys, causing significant organ damage and failure that may ultimately be fatal.1,2 Approximately 20,000 people across the US, France, Germany, Italy, Spain and the UK live with AL amyloidosis classified as Mayo stage IIIa or IIIb disease.3

CAEL-101 is currently being evaluated in the Cardiac Amyloid Reaching for Extended Survival (CARES) Phase III clinical programme in combination with standard-of-care (SoC) therapy in AL amyloidosis. Two parallel Phase III trials in patients with Mayo stage IIIa disease and in patients with Mayo stage IIIb disease respectively are ongoing.4,5

Marc Dunoyer, Chief Executive Officer, Alexion, said: “With a median survival time of less than 18 months following diagnosis, there is an urgent need for new treatments for this devastating disease. CAEL-101 has the potential to be the first therapy to target and remove amyloid deposits from organ tissues, improve organ function, and, ultimately, lead to longer lives for these patients.”

In 2019 Caelum and Alexion first entered into a collaboration whereby Alexion acquired a minority equity interest and an exclusive option to acquire the remaining equity in Caelum. Alexion currently consolidates Caelum and reflects a non-controlling interest of $150m.

Upon closing the acquisition, which is expected to take place on 5 October 2021, Alexion will pay Caelum the agreed option exercise price of approximately $150m, with the potential for additional payments of up to $350m upon achievement of regulatory and commercial milestones.
