ImmunoCellular Therapeutics Announces Issuance of Key Patent for ICT-121 Cancer Vaccine

LOS ANGELES--(BUSINESS WIRE)-- ImmunoCellular Therapeutics, Ltd. ("ImmunoCellular") (NYSE MKT: IMUC) announced that the US Patent and Trademark Office (USPTO) has issued a key patent application covering ICT-121, an immunotherapeutic vaccine targeting CD133, an important cancer stem cell marker that is commonly overexpressed on a broad range of solid tumors. The patent includes claims covering composition of matter as well as methods of use. Specifically, the claims encompass immunogens comprising a CD133 epitope and variants thereof as well as methods of using such immunogens in immunization and to elicit cytotoxic T lymphocyte responses that are specific for tumor cells expressing HLA-A2.

"This issued patent provides significant protection for ICT-121 with what we believe are broad claims, and is an important addition to ImmunoCellular's intellectual property estate for our cancer vaccines and monoclonal antibodies," said Andrew Gengos, ImmunoCellular Chief Executive Officer. "We believe that our growing IP asset strengthens our leadership position in the cancer immunotherapy field, and we look forward to continuing to advance our cancer immunotherapy product candidates through the development process."

ICT-121 is a dendritic cell vaccine. CD133 is highly expressed on cancer stem cells on most solid tumors, including brain, colon, non-small cell lung, melanoma, pancreatic and breast cancers. ImmunoCellular plans to support an investigator-sponsored, 20-patient phase I trial in recurrent glioblastoma at Cedars-Sinai Medical Center.
