Acalabrutinib granted FDA Breakthrough Designation for MCL
AstraZeneca and its hematology research and development center of excellence, Acerta Pharma, announced that the FDA has granted Breakthrough Therapy Designation for acalabrutinib for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. Acalabrutinib is a highly-selective, potent Bruton tyrosine kinase (BTK) inhibitor in development for the treatment of multiple B-cell cancers.
The Breakthrough Therapy Designation is designed to expedite the development and regulatory review of new medicines that are intended to treat a serious condition and that have shown encouraging early clinical results, which demonstrate substantial improvement on a clinically-significant endpoint over available medicines and when there is significant unmet medical need.
Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “New treatments are urgently needed for people with mantle cell lymphoma who relapse or do not respond to current therapy. Breakthrough Therapy Designation for acalabrutinib will help us bring this potential new medicine to appropriate patients as quickly as possible.”
The FDA granted Breakthrough Therapy Designation based on the totality of clinical data from the acalabrutinib development program, including data from the Phase II ACE-LY-004 clinical trial in patients with relapsed or refractory MCL.
Flavia Borellini, Ph.D., Acerta Pharma Chief Executive Officer, said: “This is an exciting regulatory milestone for our work in hematology. Acalabrutinib is a potent, irreversible BTK inhibitor with a high degree of specificity for its target. If approved, it could be a clinically-meaningful treatment option for patients with this devastating disease.”
This is the fifth Breakthrough Therapy Designation that AstraZeneca has received from the FDA for an oncology medicine since 2014 and the first for the Company in hematology. The acalabrutinib development program includes both monotherapy and combination therapies for a broad range of blood cancers and solid tumors.
