US FDA Accepts Regulatory Submission for Acalabrutinib and Grants Priority Review

August 2, 2017 -- AstraZeneca and its hematology research and development center of excellence, Acerta Pharma, today announced that the US Food and Drug Administration (FDA) has accepted and granted Priority Review for the New Drug Application (NDA) for acalabrutinib, an investigational, highly selective, potent, Bruton tyrosine kinase (BTK) inhibitor.

The NDA is based on results from the Phase II ACE-LY-004 clinical trial, which evaluated the safety and efficacy of acalabrutinib in patients with relapsed/refractory mantle cell lymphoma (MCL) who have received at least one prior therapy. This follows the FDA’s recent Breakthrough Therapy Designation for acalabrutinib.

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer, said: “FDA’s acceptance of the acalabrutinib application and Priority Review illustrates the impact it could have on patients with relapsed or refractory mantle cell lymphoma as we work to bring this potential medicine to those in need as quickly as possible.”

Priority Review is granted to applications for medicines that, if approved, would offer a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions.1 The Prescription Drug User Fee Act (PDUFA) date is during the first quarter of 2018.

Flavia Borellini, PhD, Acerta Pharma Chief Executive Officer, said: “We believe acalabrutinib has the potential to be a very important treatment option for patients with this life-threatening blood cancer. The FDA’s NDA acceptance exemplifies our progress in the acalabrutinib development program and continues our momentum as we seek to transform care for people with hematologic malignancies.”

Results from the ACE-LY-004 clinical trial will be submitted for presentation at a forthcoming medical meeting. The acalabrutinib development program includes both monotherapy and combination therapies in a broad range of blood cancers and solid tumors. The program includes the Phase III ACE-LY-308 clinical trial evaluating acalabrutinib as a 1st-line treatment for patients with MCL.2

About Mantle Cell Lymphoma (MCL)

Mantle cell lymphoma (MCL) is an aggressive B-cell non-Hodgkin lymphoma (NHL) with poor prognosis.3,4,5,6 MCL accounts for approximately 3% to 6% of new NHL cases in Western countries each year, with an annual incidence of 0.5 per 100,000 persons and an estimated prevalence of 3.5/100,000.4,7 The median age at diagnosis is 68 years, with a 3:1 male predominance.4

About a­calabrutinib

Acalabrutinib is an investigational, highly selective, potent, covalent inhibitor of Bruton tyrosine kinase (BTK) with minimal off-target activity observed in pre-clinical trials.8,9,10 This potential new medicine is in development for the treatment of multiple B-cell and other cancers. The acalabrutinib development program includes both monotherapy and combination therapy strategies in chronic lymphocytic leukemia (CLL), MCL, Waldenström macroglobulinemia, follicular lymphoma, diffuse large B-cell lymphoma, and multiple myeloma, as well as monotherapy and combination trials in solid tumors. In total, more than 25 acalabrutinib clinical trials with more than 2,000 patients are underway or have completed. Acalabrutinib was granted Orphan Drug Designation by the FDA for the treatment of patients with MCL in September 2015 and Breakthrough Therapy Designation by the FDA on August 2017 for the treatment of patients with MCL who have received at least one prior therapy. Acalabrutinib is a potential new medicine not approved for any current use.
