Evaluation of Safety and Efficacy of Patients With Four and More Symptomatic Brain Metastases of Melanoma

Phase 2

Terminated

• Conditions: Metastatic Melanoma; Brain Metastases
• Interventions: Biological: Nivolumab; Biological: Ipilimumab

• Registration Number: NCT03728465
• Lead Sponsor: University Hospital Tuebingen

Brief Summary

Up to 50% of patients with unresectable metastatic melanoma will develop brain metastases during their lifetime. A possible treatment options for patients with brain metastases are surgery and radiotherapy but usually for lesions in the range of \< 3 brain metastases. This study was performed to evaluate the addition of immune checkpoint inhibitors in patients with stage IV melanoma with \> 3 symptomatic brain metastases, who are not eligible for surgery or radiosurgery.

Detailed Description

Brain metastases are a frequent problem in patients with melanoma. Up to 50% of patients with unresectable metastatic melanoma will develop brain metastases during their lifetime with a median overall survival of 4 months. Surgical removal or stereotactic radiosurgery of brain metastases can improve overall survival in patients with a limited number of lesions, usually in the range of one to three brain metastases depending on neuroanatomical localization. This benefit is no longer present when considering patients with \> 3 brain metastases. As cytotoxic chemotherapy and multiple chemotherapeutic agents show only limited activity in \> 3 brain metastases patients, immune checkpoint inhibitors such as ipilimumab and nivolumab offer new opportunities to improve disease outcomes for these patients.

This open label phase II study evaluates safety and efficacy of combined treatment with ipilimumab and nivolumab in patients with stage IV melanoma with four or more symptomatic brain metastases, who are not eligible for surgery or radiosurgery.

• Patient must agree to the cerebro-spinal fluid (CSF) collections according to the study protocol
• Patients naïve for systemic treatment are eligible
• Patients pretreated with systemic immunotherapy, targeted therapy or chemotherapy are eligible (exception: previous treatment with the combination of CTLA-4 and PD-1 antibodies)
• Patients must have recovered completely from any treatment-related acute toxicity associated with prior therapy
• At least two weeks must have passed since the last systemic anti-cancer treatment
• Patients with prior local therapy of brain metastases are eligible
• Patients may have received irradiation therapies: A) None; B) Whole brain irradiation only, C) Stereotactic irradiation of single or few metastases, D) Combined B+C)
• Screening laboratory values within 14 days prior to registration must meet the criteria: WBC ≥ 2,000/μL, Neutrophils ≥ 1,500/μL, Platelets ≥ 100 x103/μL, Hemoglobin > 9.0 g/dL, Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min, AST/ALT ≤ 3 x ULN, total bilirubin ≤ 1.5 x ULN (except patients with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL), INR ≤ 1.5
• ECOG Performance Status 0, 1 or 2
• Expected life expectancy of ≥ 3 months
• Males and females ≥ 18 years old
• Negative serum pregnancy test within 24 hours prior to the start of study drug for women of childbearing potential (WOCBP)
• Women must not be breastfeeding
• WOCBP must agree to follow instructions for method(s) of contraception, as indicated in the ICF, throughout the study and for 23 weeks after the last dose of investigational drug
• Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception, as indicated in the ICF, throughout the study and for a period of 31 weeks after the last dose of investigational drug. In addition, male patients must be willing to refrain from sperm donation during this time
• Azoospermic males are exempt from contraceptive requirements. WOCBP who are permanently not heterosexually active are also exempt from contraceptive requirements, but must still undergo pregnancy testing as previously described.

• History of organ transplantation
• Active infection requiring systemic therapy
• Active, known or suspected autoimmune disease (exceptions: patients with controlled Type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders not requiring systemic treatment).
• Interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity
• Any serious or uncontrolled medical disorders thatmay increase the risk associated with study participation or study drug administration, impair the ability of the patient to receive protocol therapy, or interfere with the interpretation of study results in the opinion of the investigator
