SEATTLE and SOUTH SAN FRANCISCO, Calif., Jan. 08, 2016 (GLOBE NEWSWIRE) -- 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 LV305 and G305 for the treatment of soft tissue sarcoma. LV305 and G305 are the complementary agents that comprise CMB305, Immune Design's "prime boost" cancer immunotherapy product candidate.
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.
CMB305 is a cancer immunotherapy product candidate that involves the sequential dosing of LV305 and G305. LV305 is a hybrid vector from the ZVex™ discovery platform that specifically targets dendritic cells (DCs) in vivo and delivers the RNA for NY-ESO-1, enabling the DCs to express the entire tumor antigen and potentially induce a diverse set of CTLs targeting NY-ESO-1 in tumors. G305, in contrast, is designed to boost the CTL response via the induction of antigen-specific CD4 "helper" T cells. G305 consists of recombinant NY-ESO-1 protein formulated with a proprietary synthetic small molecule called glucopyranosyl lipid A (GLA), the novel TLR4 agonist at the core of the GLAAS™ platform. CMB305 is intended to be an "off-the shelf" therapy that does not require patient-specific manufacturing or ex vivo manipulation of patient samples. Immune Design has conducted prior studies to establish the safety and individual immunologic activity of LV305 and G305. CMB305 is currently being evaluated in a Phase 1B trial in patients with locally advanced, relapsed or metastatic solid cancers whose tumors express NY-ESO-1 and a randomized Phase 2 trial of CMB305 combined with Genentech's investigational cancer immunotherapy, atezolizumab (MPDL3280A; anti-PD-L1) in patients with soft tissue sarcoma, pursuant to a collaboration with Genentech.
