OPT-821

William Tap, M.D.

Sarcoma patients are at high risk for their cancer to recur even when the sarcoma has been removed surgically or treated with radiation or chemotherapy. The patients in the study will be randomized (like flipping a coin) to receive either a vaccine that is combined with an immune system stimulant or the immune system stimulant alone. The immune system stimulant is called OPT-821 and is an immunological booster. The trivalent vaccine is being developed to teach the patient's immune system to recognize 3 types of sugars called GM2, GD2 and GD3 that are found primarily on the surface of sarcoma cells. If the trivalent vaccine can stimulate the patient's immune system to develop antibodies which recognize and target the GM2, GD2 and GM3 sugars, then the patient's antibodies could attack and kill any remaining sarcoma cells potentially preventing the recurrence of sarcoma.

This study is a Phase II randomized, double-blind, multi-center study of a trivalent ganglioside vaccine plus the immunological adjuvant OPT-821 (Arm A) versus OPT-821 alone (Arm B) for patients with metastatic sarcoma at initial presentation or with relapsed disease who have been rendered disease-free following either surgical resection or multi-modality therapy. The primary aim of this study is to demonstrate the efficacy of vaccine therapy over non-specific immune therapy. Another aim of this study is to obtain sufficient data to further the development of this specific vaccine therapy as well as guide future study designs for therapeutic cancer vaccines in general.

To be eligible, patients must have histologically confirmed sarcoma, must be clinically free of disease after surgery or multimodality therapy, and must be within 8 weeks of completion of such therapy. Given the limited data regarding ganglioside expression in Ewing sarcoma, rhabdomyosarcoma, and gastrointestinal stromal tumors, patients with these sarcoma subtypes with the exception of pleomorphic/anaplastic rhabdomyosarcoma will be excluded. Patients must have a history of distant metastatic disease; patients with locally recurrent disease only will not be eligible, as these patients demonstrate a different natural history from those with metastatic disease.

All treatment will be performed in the outpatient setting. Patients will be randomized in a 1:1 ratio to receive a total of 10 treatments of either the vaccine plus OPT-821 (Arm A) or OPT-821 alone (Arm B). Treatment will be administered on Visit Weeks 1, 2, 3, 8, 16, 28, 40, 52, 68, and 84. All patients will receive 150 mcg of OPT-821.

Trivalent Ganglioside Vaccine With Immunological Adjuvant or Immunological Adjuvant Alone in Metastatic Sarcoma Patients Who Are Rendered Disease Free

A Randomized, Multicenter, Double-Blind, Phase II Trial of a KLH Conjugated Trivalent Ganglioside Vaccine Containing GM2, GD2 Lactone, and GD3 Lactone With the Immunological Adjuvant OPT-821 Versus OPT-821 Alone in Metastatic Sarcoma Patients Who Are Rendered Disease Free

The primary objective is to compare the progression-free survival (PFS) over time.

Progression free survival is defined as the time from randomization until any evidence of tumor growth or appearance anywhere in the body or death from any cause as determined by the principal investigator at each site. The principal investigator will determine Progression-free survival by using CT scans to evaluate disease recurrence. For the purpose of this study, progression of disease is defined as the development of tumor growth or recurrence at any site of the body as determined by the principal investigator at each study site or death from disease

To compare the overall survival over time, to estimate the median and 3-year progression-free survival.
