CTLA-4 Blockade and Low Dose Cyclophosphamide in Patients With Advanced Malignant Melanoma

Stopped early · Phase 2

Conditions studied: Melanoma

In brief

The purpose of this study is to see whether the combination of low-dose Cyclophosphamide and Anti-CTLA4 (Ipilimumab) will stop tumor growth in patients with advanced skin cancer. The investigators expect to see an increase in response rate of the combination over Anti-CTLA-4 alone and estimate a response rate of approximately 20 % in the proposed population.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Men \& women, ages ≥18
• Willing/able to give written informed consent.
• Histologic diagnosis of unresectable AJCC Stage III/IV malignant melanoma
• At least 2wks must have elapsed since last chemotherapy, immunotherapy, hormonal therapy, radiotherapy or major surgery \& beginning of protocol therapy. At least 6wks for nitrosoureas, mitomycin C, \& liposomal doxorubicin
• Toxicity related to prior therapy must either have returned to ≤ grade 1 or baseline.
• Two punch tumor biopsy at Screening and Wk12 (4mm diameter) must be provided for immune analysis/staining if patients have accessible disease. Biopsies are optional during the Maintenance Period.Site of tumor biopsy s/n be only site of measurable disease. Minimum of 5 out of 1st 10 patients in stage I of the protocol must have biopsy accessible disease.
• Patients must have measurable disease defined as @ least 1 lesion that can be accurately measured in @ least 1 dimension (longest diameter to be recorded) as >20 mm with conventional techniques or as >10 mm with spiral CT scan.
• Required values for initial laboratory tests:
• WBC ≥ 2000/uL
• ANC ≥ 1000/uL
• Platelets ≥ 50 x 103/uL
• Hemoglobin ≥ 9.5 g/dL
• Creatinine ≤ 3.0 x ULN
• AST/ALT ≤ 2.5 x ULN for patients without liver metastasis, ≤ 5 x ULN for patients with liver metastasis
• Bilirubin ≤ 3.0 x ULN, (except patients with Gilbert's Syndrome, who must have a total bilirubin less than 3.0 mg/dL)
• Life expectancy of at least 4mos
• Patients w/stable, treated central nervous system (CNS) metastasis are eligible
• ECOG Performance Status Score 0-1
• Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout study \& for up to 26wks after the last dose of investigational product, in such a manner that the risk of pregnancy is minimized.
• WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not post-menopausal. Post-menopause is defined as:
• Amenorrhea ≥ 12 consecutive months w/o another cause, or
• For women with irregular menstrual periods and taking hormone replacement therapy (HRT), documented serum follicle-stimulating hormone (FSH) level ≥ 35 mIU/mL.
• Women who are using oral contraceptives, other hormonal contraceptives (vaginal products/skin patches/implanted/injectable products), mechanical products such as an intrauterine device or barrier methods (diaphragm/condoms/ spermicides) to prevent pregnancy,are practicing abstinence or where their partner is sterile (eg vasectomy) should be considered to be of childbearing potential.
• WOCBP must have a negative urine or serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) w/in 72hrs before the start of ipilimumab.
• Men of fathering potential must be using an adequate method of contraception to avoid conception throughout the study [and up to 26wks after last dose of investigational product] in a way that risk of pregnancy is minimized.

You may not qualify if…

• Any other malignancy from which patient has been disease-free for less than 5yrs, with the exception of adequately treated \& cured basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix.
• Autoimmune disease: Patients with a history of inflammatory bowel disease, including ulcerative colitis and Crohn's Disease, are excluded from this study, as are patients with a history of symptomatic disease (eg rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [eg Wegener's Granulomatosis]); motor neuropathy considered of autoimmune origin (eg Guillain-Barre Syndrome and Myasthenia Gravis).
• Any underlying medical or psychiatric condition, which in the opinion of investigator will make administration of ipilimumab hazardous or obscure interpretation of AEs, like a condition associated with frequent diarrhea.
• Uncontrolled or significant cardiovascular disease
• Any non-oncology vaccine therapy used for prevention of infectious diseases (for up to 1mo before/after any dose of ipilimumab).
• History of prior treatment with ipilimumab or prior CD137 agonist or CTLA 4 inhibitor or agonist.
• Concomitant therapy with any of following: IL 2, interferon, other non-study immunotherapy regimens; immunosuppressive agents; other investigation therapies; or chronic use of systemic corticosteroids (>60mg prednisone/day).
• Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (eg infectious) illness.
• Women of childbearing potential (WOCBP), defined above who:
• are unwilling/unable to use an acceptable method of contraception to avoid pregnancy for their entire study period and for at least 26wks after cessation of study drug, or
• have a positive pregnancy test at baseline, or
• are pregnant or breastfeeding.
• Persons of reproductive potential who are unwilling to use an adequate method of contraception throughout treatment \& for at least 26wks after ipilimumab is stopped.
