Gritstone Oncology Announces FDA Fast Track Designation for GRANITE-001 for the Treatment of Colorectal Cancer
“Colorectal cancer remains a major contributor to cancer deaths and has not yet proved very amenable to first generation immunotherapy,” said
Ongoing Phase 1/2 Clinical Study
GRANITE-001 in combination with immune checkpoint blockade is being evaluated in a Phase 1/2 clinical study called GO-004 for the treatment of patients with common solid tumors, including metastatic non-small cell lung cancer, microsatellite stable colorectal cancer, gastroesophageal cancer, and bladder cancer. The Phase 1 study includes two parts: in part A patients receive an adenovirus-based prime with escalating doses of an RNA-based boost vaccinations in combination with anti-PD-1 therapy; and in part B patients receive the prime and the boost vaccinations at the selected dose in combination with both anti-PD-1 and anti-CTLA-4 immuno-modulatory antibodies.
GRANITE-001 is Gritstone Oncology’s lead, personalized tumor-specific immunotherapy product candidate. It is engineered to elicit a significant T-cell response (particularly CD8+ cytotoxic T-cells) against mutation-derived tumor-specific neoantigens, or TSNA, identified for each patient through the company’s proprietary EDGE™ artificial intelligence platform. GRANITE-001 consists of two components, first a priming adenoviral vector followed by monthly boosting with an RNA vector, each containing the same 20 patient-specific TSNA.
