Clinical Programs Update

SIGNAL. The company’s ongoing SIGNAL clinical trial is evaluating pepinemab for the treatment of Huntington’s disease.  As of March 30, 2020, 206 of the planned 265 study subjects in cohort B of the trial have completed the planned 18 months of treatment and a safety follow-up and 16 have withdrawn.  Of the remaining 43 subjects, 38 have completed 16 of the 18 monthly visits specified in the trial protocol. The company is working with clinical investigators and sites to safely accelerate completion of remaining visits and assessments, and will provide further updates as warranted.

CLASSICAL-Lung. The CLASSICAL-Lung study is evaluating pepinemab in combination with avelumab for the treatment of advanced (stage IIIB/IV) non-small cell lung cancer (NSCLC).  Of the 62 subjects enrolled in this phase 2 trial, four remain on study with continuing objective response or stable disease. Vaccinex has been invited to present its near topline data at the virtual ASCO conference in early June 2020.

About Pepinemab

Pepinemab, also known as VX15/2503, is a humanized monoclonal antibody that binds and blocks the signaling activity of semaphorin 4D (SEMA4D) which is an extracellular signaling molecule that regulates the migration and function of immune and inflammatory cells.  Preclinical studies have demonstrated that antibody blockade of SEMA4D promotes tumoricidal immune activity in tumors and prevents brain damage in neuroinflammatory and neurodegenerative disease models.  Vaccinex is focused on the development of pepinemab for the treatment of cancer and neurodegenerative diseases including Huntington’s and Alzheimer’s disease.
