It’s one step backward in order to take two steps forward at Zentalis Pharmaceuticals Inc. In a restructuring to help fund the second part of its potentially registration-enabling Denali study, Zentalis has laid off 40% of its workforce. The clinical trial of azenosertib, Zentalis’ lead candidate and a WEE1 kinase inhibitor, is for treating advanced solid tumors and hematologic malignancies. The therapy is designed to make cancer cells self-destruct.
The deaths of two cancer patients treated with the small molecule azenosertib has prompted the U.S. FDA to place a partial clinical hold on a phase I study and two phase II studies from Zentalis Pharmaceuticals Inc. The deaths are presumed by Zentalis to be from sepsis. Both patients who died were in the phase II Denali study of platinum-resistant ovarian cancer.
