OncoVAX® is the first cancer vaccine that both prevents cancer recurrence and addresses the diversity of cancer cells. In this pivotal randomized, multicenter Phase IIIb study in patients with Stage II colon cancer, OncoVAX is designed to use a patient's own cancer cells to mobilize the body's immune system to prevent the return of colon cancer following surgery.

Study summary:

OncoVAX is an active specific immunotherapeutic (ASI) stimulating a patient's immune response to autologous (patient-specific) tumor cells. It is comprised of sterile, live but non-dividing tumor cells obtained following standard-of-care surgical tumor resection for Stage II colon cancer. Within 35 days following surgery, patients are immunized with OncoVAX to prevent disease recurrence, which is incurable and occurs in up to 35% of patients. Patients are given three vaccinations once per week for three weeks, followed by a booster vaccination after six months. A previously completed Phase III trial published in The Lancet showed that OncoVAX cut the risk of recurrence by 61% in patients with Stage II colon cancer. The primary endpoint is Disease-Free Survival: defined as the time from curative surgery to the objective test confirming tumor recurrence or death due to any cause. The secondary endpoints are Overall Survival and Recurrence-Free-Interval. An interim analysis will be performed at a significance level of 0.005 once 2/3 of anticipated events have occurred, resulting in a significance level of 0.0483 at the end of the study. A total of 550 patients is planned, randomized 1:1 to receive OncoVAX® plus surgery (n=275) or surgery alone (n=275).


Inclusion Criteria: - Patients must have Stage II (IIA = T3N0M0, IIB = T4aN0M0, IIC = T4bN0M0) disease. - Patients must have undergone curative resection and have no evidence of residual or metastatic disease. - Following curative resection patients must have a CEA within normal limits. If elevated prior to resection, it must return to normal within 21 days post surgery and prior to randomization. Exclusion Criteria: - Patients with prior radiation therapy or chemotherapy or a prior malignancy of any type will be excluded. However, subjects with prior, curatively-treated squamous cell or basal cell carcinoma of the skin or carcinoma in situ of the cervix will be eligible for participation in this study. - Patients with more than one malignant primary colon cancer will be excluded.
