Phase I Oncovir Poly IC:LC and NY-ESO-1/gp100

Study drug will be administered open-label as an intravenous solution, followed by observation. Study drug will be supplied as a liquid intravenous solution in vials containing 10 mg/mL of CP870,893. CP 870,893 will be administered at a dosage of 0.01, 0.025 or 0.05 mg/kg at 0.24 mg/mL infused via a syringe pump over 15 minutes, or at 0.1 or 0.2 mg/kg/dose as an i.v. infusion in saline at a concentration of 0.24 mg/mL in an IV bag of up to 100 mL over 30 minutes (controlled by a volumetric pump) for not more than 30 minutes, with a 10 cc flush at the end that should be administered at the same rate as the CP 879,893 infusion.

NY-ESO-l 157-165 (165V) and gpl002 80-288 (288V) peptides each at a dose of 0.5 mg will be emulsified with Montanide ISA 51 VG and administered to all patients in the study at Weeks 1,3, 5, 7, 9, 11, 17, 21, 25 33, 41, and 53. Peptides will be administered as a total of 6 deep subcutaneous (s.c.) injections into alternating lower extremities one hour after CP 870,893 infusions.

The dosage of poly IC:LC chosen for the current trials has been used safely in over one hundred patients with central nervous system (CNS) malignancies enrolled in nitrates and bone turnover (NABT) trials. The injection of 1000 mcg will be made deeply subcutaneously into the same limb as the peptides/Montanide ISA 51 VG, at least 5 cm. proximal to the peptides vaccination site. Poly IC:LC will be administered to all patients in the study at Weeks 1, 3, 5, 7, 9, 11, 17, 21, 25 33, 41, and 53 one hour after CP 870,893 infusion.
