Immune Design Receives Orphan Drug Designation for G100 Intratumoral Product Candidate

Immune Design (Nasdaq:IMDZ), a clinical-stage immunotherapy company focused on oncology, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation for its investigational intratumoral therapy, G100, for the treatment of follicular non-Hodgkin’s lymphoma.
Orphan Drug Designation is granted by the FDA Office of Orphan Drug Products to products that treat rare diseases. The FDA defines rare diseases as those affecting fewer than 200,000 people in the United States. Orphan Drug Designation provides the sponsor certain benefits and incentives, including a period of marketing exclusivity for the first marketing application, if regulatory approval is received for the designated indication, potential tax credits for certain activities and waiver of certain administrative fees.G100 is a product candidate from Immune Design’s GLAAS^® discovery platform. It contains a potent synthetic small molecule toll-like receptor-4 (TLR-4) agonist, Glucopyranosyl Lipid A (GLA), and is the lead product candidate in Immune Design’s Antigen Agnostic approach. It leverages the activation of both innate and adaptive immunity, including Dendritic Cells, in the tumor microenvironment to create an immune response against the tumor’s preexisting diverse set of antigens. A growing set of clinical and preclinical data have demonstrated the ability of G100 to activate tumor-infiltrating lymphocytes, macrophages and dendritic cells, and promote antigen-presentation and the recruitment of T cells to the tumor.  The ensuing induction of local and systemic immune responses has been shown to result in local and abscopal (shrinking of tumors outside the scope of the localized treatment) tumor control in preclinical studies. G100 was evaluated in a Phase 1 study in Merkel cell carcinoma patients and produced a 50% overall response rate per protocol and a favorable safety profile. Currently, G100 is being evaluated as both a monotherapy (with local radiation) and in combination with Merck’s anti-PD-1 agent, pembrolizumab, pursuant to a clinical collaboration with Merck, in a randomized Phase 1/2 trial in patients with follicular non-Hodgkin’s lymphoma.CMB305, Immune Design’s prime-boost cancer immunotherapy product candidate, has previously been designated orphan drug status for soft tissue sarcoma by the FDA, and each of the two agents comprising CMB305 also have both U.S. and European Orphan drug designation for soft tissue sarcoma.
