- Identified cases of agranulocytosis, possibly drug-related, in some cases associated with sepsis and death
- Increased blood cell count monitoring to weekly in ongoing Phase 3 program
- Discussions with FDA and DSMB ongoing
ARDSLEY, NY, USA I November 15, 2017 I Acorda Therapeutics, Inc. (Nasdaq:ACOR) today announced that it has increased the frequency of blood cell count monitoring for participants to weekly in its Phase 3 program of tozadenant for Parkinson’s disease. The Company took this action in response to cases of agranulocytosis, possibly drug-related, and in some cases associated with sepsis and death. Agranulocytosis is the absence of white blood cells, which fight infection. The Company also has paused new enrollment in the long-term safety studies, pending further discussion with the independent Data Safety Monitoring Board (DSMB) and the United States Food and Drug Administration (FDA).
The Phase 3 program includes an ongoing pivotal efficacy and safety study (CL05) and two long-term safety studies (CL05 extension and CL06).
Including the previously conducted Phase 2b study, approximately 890 patients have been exposed to tozadenant and 234 have been exposed to placebo. This corresponds to approximately 300 patient years of tozadenant exposure and 75 patient-years of placebo. There have been seven cases of sepsis, all in the tozadenant groups, five of which were fatal. Four of the sepsis cases were associated with agranulocytosis, two had no white blood cell counts available at the time of the event and one had a high white blood cell count.
“We have taken these steps in the best interests of the safety of patients in the tozadenant studies, which is our top priority,” said Ron Cohen, M.D., Acorda’s President and CEO. “Contingent on further input from the DSMB and FDA, we continue to expect to report efficacy and safety results of the double-blind Phase 3 study in the first quarter of 2018.”
The Company will host a conference call today at 8:30 a.m. ET. To participate, please dial (866) 393-4306 or (734) 385-2616 and reference the access code 7587067.

About Tozadenant
Tozadenant is an oral adenosine A2a receptor antagonist currently in Phase 3 development as an adjunctive treatment to levodopa in Parkinson’s disease patients to reduce OFF time. A2a receptor antagonists have the potential to be the first new class of drug approved in the U.S. for improvement of motor symptoms in Parkinson’s disease in over 20 years. Following a successful Phase 2b clinical trial, published in The Lancet in 2014, Acorda is conducting a Phase 3 trial (CL05), in which tozadenant is taken for 24 weeks in addition to a person’s other Parkinson’s disease therapies. The trial is being conducted under a special protocol assessment, or SPA, from the FDA and is comparing two of the dose arms of tozadenant, 60 mg and 120 mg which were selected from the prior Phase 2b clinical trial, versus placebo. The trial is assessing improvement of motor function and activities of daily living in people with Parkinson’s while taking tozadenant. Data from this trial are expected in the first quarter of 2018. A separate open-label, long-term safety study (CL06) commenced enrollment in April 2017.
