Patient case: 39-year-old female with melanoma; genetic feature: KIT (N822Y)

Clinical trial: Yttrium90, Ipilimumab, & Nivolumab for Uveal Melanoma With Liver Metastases

Summary: Reports to date show limited efficacy of immunotherapy for uveal melanoma. Recent experimental and clinical evidence suggests synergy between radiation therapy and immunotherapy. The investigators will explore this synergy with a feasibility study of 18 patients with uveal melanoma and hepatic metastases who will receive SirSpheres Yttrium-90 selective internal hepatic radiation followed by immunotherapy with the combination of ipilimumab and nivolumab.

Detailed description: Despite rapid improvements in the treatment of cutaneous melanoma, there has been little advance in therapy for uveal melanoma with hepatic metastases, an fatal orphan disease with no established therapy. Studies by Dr. Sato and others have described some activity for selective internal radiation with Yttrium90 microspheres (SIR-Spheres).There is limited activity as single agents for both the immunotherapy drugs ipilimumab (anti-CTLA-4) and nivolumab (anti-PD-1). In cutaneous melanoma the combination of ipilimumab and nivolumab is clearly synergistic with improvement in response rates and progression-free survival over single agents; however this has yet to be established for uveal melanoma.
  Recent experimental and clinical evidence suggests additional synergy between radiation therapy and immunotherapy. This synergy seems most evident when radiation is given through large fraction stereotactic treatments or brachytherapy. The investigators will explore this synergy with a feasibility study of 18 patients who will receive SirSpheres Yttrium-90 selective internal radiation given through the hepatic artery in two treatments followed by immunotherapy with the combination of ipilimumab and nivolumab. The immunotherapy will be given with the dose and schedule that has been established and FDA-approved for cutaneous melanoma. Because of the generally low toxicity of Yttrium-90 selective internal radiation therapy the investigators feel it can be given in full dosage prior to full dosage of immunotherapy.

Eligibility: Inclusion Criteria:
  1. Histologic diagnosis of metastatic uveal melanoma.
  2. Patients must have measurable disease as defined by RECIST (see Section 6).
  3. Patients must have liver metastasis
  4. Patients must have no more than one prior systemic therapeutic regimen. This includes chemotherapy, biologic therapy, biochemotherapy, or investigational treatment. This does not include any therapies given in the adjuvant setting. No prior anti-CTLA4 therapy. Prior anti PD-1 or anti-PDL-1 antibody therapy is acceptable.
  5. No concomitant therapy with any of the following: IL-2, interferon or other non-study immunotherapy regimens; cytotoxic chemotherapy; immunosuppressive agents; other investigation therapies; or chronic use of systemic corticosteroids.
  6. Patients with prior selective internal radiation are candidates are eligible as long as they are candidates for repeat procedures and they have demonstrated progressive disease.
  7. Age ≥ 18 years.
  8. No known infection with HIV. Due to the mechanism of action of ipilimumab, activity and side effects in an immune compromised patient are unknown.
  9. No active infection with Hepatitis B.
  10. No active infection with Hepatitis C.
  11. ECOG performance status 0 or 1.
  12. Women must not be pregnant or breast-feeding due to unknown effects of treatments on the unborn fetus. All women of childbearing potential must have a blood test within 72 hours prior to randomization to rule out pregnancy. Women of childbearing potential and sexually active males must be strongly advised to use an accepted and effective method of contraception. Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of investigational product, in such a manner that the risk of pregnancy is minimized. Sexually mature females who have not undergone a hysterectomy or who have not been postmenopausal naturally for at least 24 consecutive months (i.e., who have had menses at some time in the preceding 24 consecutive months) are considered to be of childbearing potential. Women who are using oral contraceptives, other hormonal contraceptives (vaginal products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy, or are practicing abstinence or where their partner is sterile (e.g.,vasectomy) should be considered to be of childbearing potential.
  13. Patients must have the following lab values obtained < 4 weeks prior to starting treatment:
  -  WBC ≥2000/uL
  -  ANC ≥1500/mcL
  -  Platelets ≥ 100,000/mcL
  -  Hemoglobin ≥ 8g/dL
  -  Creatinine ≤ 3.0 xULN
  -  AST and ALT < 2.5 x ULN
  -  Bilirubin ≤ 2.0 x ULN, (except patients with Gilbert's Syndrome, who must have a total bilirubin less than 3.0 mg/dL)
  -  Albumin ≥ 3g/dL
  Exclusion Criteria
  1. Patients are excluded if they have liver tumor volume > 50%
  2. Patients are excluded if they have active CNS metastases. Patients with history of CNS metastases must have MRI scans that show stability of brain metastases for 8 weeks.
  3. Patients are excluded if they have a history of any other malignancy from which the patient has been disease-free for less than 2 years, with the exception of adequately treated and cured basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix, or stage 1 or 2 cutaneous melanoma
  4. Patients are excluded if they have a history of autoimmune disease, as follows: Patients with a history of inflammatory bowel disease are excluded from this study as are patients with a history of symptomatic disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], Systemic Lupus Erythematosus, autoimmune vasculitis [e.g., Wegener's Granulomatosis]). Patients with a history of Guillain-Barre Syndrome are excluded but myasthenia gravis or psoriasis is acceptable.
  5. Patients are excluded for any underlying medical or psychiatric condition which, in the opinion of the investigator, will make treatment hazardous or obscure the interpretation of adverse events, such as a condition associated with frequent diarrhea.
  6. Patients are excluded if they have a history of prior treatment with ipilimumab or CTLA-4 inhibitor.
  7. Patients are excluded if they have any concurrent medical condition requiring the use of systemic steroids (the use of inhaled or topical steroids is permitted).
