Infusion and Peptide AdministrationEXPERIMENTALPatients get the study drug Oncovir poly IC:LC with or without CP 870-893. Up to 6 groups of 3 to 10 patients each will be treated in this study. The first group (between 3 and 6 patients) gets peptide vaccine with poly IC:LC. Second, third and fourth groups of 3 to 6 patients receive peptide vaccine with poly IC:LC and the antibody CP 870,893 at increasing doses from 0.01, 0.025 and 0.05 mg/kg. CP 870-893 will be given to 10 patients at a dose of 0.1 mg/kg to patients in the fifth group, and 0.2 mg/kg to the sixth group. The CP 870,893 will be given as an intravenous infusion over 30 minutes and will be given once every 2 weeks for the first 6 infusions. CP-870-893 will then be given every 4 to 6 weeks for 3 injections. The final 3 injections of CP 870,893 will be given every 8 to 12 weeks. These infusions will take place on weeks 1, 3, 5, 7, 9, 11, 17, 21, 25, 33, 41, and 53 for a total of 12 infusions.
Interventions
NameTypeDescription
CP 870,893DRUGStudy 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.
PeptidesBIOLOGICALNY-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.
Oncovir poly IC:LCBIOLOGICALThe 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.
