On Apr. 11, 2016,  the U.S. Food and Drug Administration (FDA) announced that it had granted accelerated approval to VenclextaTM (venetoclax) for the treatment of people with chronic lymphocytic leukemia (CLL) with 17p deletion, as detected by an FDA approved test, who have received at least one prior therapy. The pivotal study showed a clinically meaningful improvement (overall response rate, ORR) in 80.2 percent of people (95 percent CI 71.3-87.3). Venclexta is the first approved medicine designed to help restore a process in which cells self-destruct (apoptosis) by selectively blocking the BCL-2 protein and is Genentech’s tenth new medicine approved in the past seven years. Venclexta is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the United States and commercialized by AbbVie outside of the United States.

Possible serious side effects with Venclexta include pneumonia, low white blood cell count with fever, fever, abnormal immune response that results in low red blood cell count, low red blood cell count and tumor lysis syndrome (TLS). The most common side effects of Venclexta include low white blood cell count, diarrhea, nausea, low red blood cell count, upper respiratory tract infection, low platelet count and tiredness.

The FDA’s Accelerated Approval Program allows conditional approval of a medicine that fills an unmet medical need for a serious condition based on early evidence suggesting clinical benefit. This indication is approved under accelerated approval based on ORR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Venclexta will be available to people in the United States within approximately one week. For those who qualify, Genentech and AbbVie plan to offer patient assistance programs for people taking Venclexta.

Venclexta was granted Breakthrough Therapy Designation by the FDA for the treatment of people with previously treated (relapsed or refractory) CLL with 17p deletion. Breakthrough Therapy Designation is designed to expedite the development and review of medicines intended to treat serious or life-threatening diseases and to help ensure people have access to them through FDA approval as soon as possible. The New Drug Application for Venclexta was granted Priority Review, a designation for medicines that the FDA has determined to have the potential to provide significant improvements in the treatment, prevention or diagnosis of a disease.

A Marketing Authorization Application (MAA) has also been validated by the European Medicines Agency (EMA).
