Innovative science for new medicines.

Our lead monoclonal antibody therapeutic Pepinemab is an inhibitor of Semaphorin 4D (SEMA4D), a potent biological effector with effects on both neurodegenerative diseases like Alzheimer’s Disease and immunotherapy treatments for cancer.

Doctor With Patient

Pepinemab (VX15/2503) is a humanized monoclonal IgG4 antibody that binds and blocks the signaling activity of SEMA4D, a signaling molecule that regulates the migration and activation of immune and inflammatory cells at sites of injury or damage in the brain and in tumors.

Vaccinex is evaluating pepinemab in clinical trials for people living with Huntington’s and Alzheimer’s disease, and is exploring the potential to treat other neurological disorders.

Vaccinex is evaluating pepinemab in clinical trials of patients with solid tumors such as breast cancer, melanoma, non-small cell lung cancer and head and neck cancer.

Our Technology

Vaccinex has developed a fusion protein technology to enable the direct incorporation of multi-pass membrane proteins such as GPCRs and ion channels into the membrane of two antigenically distinct BSL1 poxviruses: MVA and FPV.

Antigen expressing virus can be readily purified and used for antibody selection employing either in vitro display or in vivo immunization methods.

Maximize your chances for success against difficult protein targets.

We provide both custom and catalog antigen virions to clients for their antibody discovery projects. Proteins retain native conformation and orientation and virions can be used on the benchtop just like purified protein.
