A Phase 1 Trial of NY-ESO-1 With GLA-SE in Patients With Unresectable or Metastatic Cancer

This is a Phase 1, open label, multicenter, multiple ascending dose trial of IDC-G305 administered by intramuscular injection in a 3+3 sequential dose escalation design. IDC-G305 is an immunotherapy consisting of recombinant NY-ESO-1 antigen and the adjuvant, GLA-SE. Patients with unresectable, relapsed or metastatic cancer but with low disease burden and indolent disease course may be considered for the trial. Tumors must express the NY-ESO-1 gene signature and tumor types that will be studied are: melanoma, ovarian, sarcoma,non-small cell lung and breast cancer. Each of three dose level cohorts will be treated contingent upon absence of dose limiting toxicity (DLT) and acceptable safety data for the preceding cohort. Initially, three patients will be scheduled to receive IDC-G305 in each dose level cohort. Dose escalation will be contingent upon the assessment of safety data obtained during the initial injections. Patients will be evaluated at baseline and at regular intervals for safety and immune response. Both cellular and humoral immunogenicity will be explored.
