Sirolimus and Vaccine Therapy in Treating Patients With Stage II-IV Ovarian Epithelial, Fallopian Tube, or Primary Peritoneal Cavity Cancer

A Phase I Clinical Trial of mTOR Inhibition With Sirolimus for Enhancing ALVAC(2)-NY-ESO-1(M)/TRICOM Vaccine Induced Anti-Tumor Immunity in Ovarian, Fallopian Tube, and Primary Peritoneal Cancer

This phase I trial studies the side effects and best dose and schedule of sirolimus when given together with vaccine therapy in treating patients with stage II-IV ovarian epithelial, fallopian tube, or primary peritoneal cavity cancer. Sirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Giving vaccine therapy together with sirolimus may be an effective treatment for ovarian, fallopian tube, or primary peritoneal cancer

PRIMARY OBJECTIVES:

I. Determine the safety of ALVAC(2)-NY-ESO-1 (M)/TRICOM vaccine with sirolimus at varying dose and schedule.

SECONDARY OBJECTIVES:

I. To determine the effectiveness of sirolimus on enhancing vaccine efficacy by assessing NY-ESO-1 specific cellular and humoral immunity: peripheral blood NY-ESO-1 specific cluster of differentiation (CD)8+ and CD4+ T-cells; peripheral blood NY-ESO-1 specific antibodies; peripheral blood frequency of CD4+CD25+forkhead box P3 (FOXP3)+ regulatory T-cells.

II. Explore time to disease progression.

OUTLINE: This is a dose-escalation study of sirolimus.

Patients receive ALVAC(2)-NY-ESO-1 (M)/TRICOM vaccine subcutaneously (SC) on day 1 and sargramostim (GM-CSF) SC on days 1-4. Patients also receive sirolimus orally (PO) once daily (QD) on days 1-14 OR 15-28 OR 1-28. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients then receive an additional course of ALVAC(2)-NY-ESO-1 (M)/TRICOM vaccine only followed by ALVAC(2)-NY-ESO-I (M)/TRICOM vaccine SC 8 weeks after completion of course 4.

After completion of study treatment, patients are followed up at 30 days, and 6 and 12 months.

Inclusion Criteria:

• Hemoglobin (Hgb) >= 8 g/dL
• Total bilirubin =< 1.5 x upper limit of normal (ULN)

• Have an Eastern Cooperative Oncology Group (ECOG) Performance Status of =< 2
• Demonstrate the ability to swallow and retain oral medication
• Patients of child-bearing potential must agree to use acceptable contraceptive methods (e.g., double barrier) during treatment

• Other serious illnesses (e.g. serious infections requiring antibiotics, bleeding disorders)
• History of severe autoimmune disorders requiring use of steroids or other immunosuppressives
• Concomitant systemic treatment with corticosteroids, anti-histamine or nonsteroidal anti-inflammatory drugs and other platelet inhibitory agents, strong inhibitors/inducers of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP450-3A4)
• Chemotherapy, radiation therapy, or immunotherapy within 4 weeks prior to first dosing of study drug (6 weeks for nitrosoureas); concomitant hormonal therapies for breast cancers are allowed

• Lack of availability of a patient for immunological and clinical follow-up assessment
• Known pulmonary hypertension
• Known hypersensitivity to sirolimus
• Evidence of current drug or alcohol abuse or psychiatric impairment, which in the investigator's opinion will prevent completion of the protocol therapy or follow-up
• Pregnant or nursing female patients
• Unwilling or unable to follow protocol requirements
• Any condition which in the investigator's opinion deems the patient an unsuitable candidate to receive study drug; (i.e., any significant medical illness or abnormal laboratory finding that would, in the investigator's judgment, increase the subject's risk by participating in this study)
