HOLON, Israel, May 31, 2017 /PRNewswire/ -- Compugen Ltd. (NASDAQ: CGEN ), a therapeutic discovery company, announced today that it anticipates a delay of several months in the submission of an investigational new drug application (IND) for COM701, Compugen's clinical candidate antibody targeting CGEN-15029/PVRIG. Previously the Company had disclosed an expectation of IND filing in Q4 of this year. The Company was recently informed by its manufacturing service provider for COM701 - a global contract development and manufacturing organization (CDMO) - that the batch of material they manufactured for Compugen's planned GLP (good laboratory practice) toxicity studies was contaminated during the manufacturing process. The contamination was discovered during quality control procedures prior to release of the affected batch and, as such, was not used in any preclinical studies. This contamination has necessitated the production of a new batch of material for the execution of these studies.
