Clinical Trial Summary

Melanoma of the eye (ocular/uveal melanoma) is an uncommon type of cancer that is associated with a high mortality. It usually disseminates rapidly throughout the body, most commonly to the liver and lungs. In this study a combination therapy with immunotherapy (ipilimumab with nivolumab) and chemotherapy (melphalan) will be assessed for the treatment of disseminated uveal melanoma. Melphalan will be administered selectively to the liver via percutaneous hepatic perfusion, limiting the systemic effect of chemotherapy. With this treatment combination we aim to find a treatment for disseminated uveal melanoma, both in the liver as in the other organs.

Description:

Uveal melanoma (UM) is an uncommon malignancy (0.6-0.7 cases/100.000/year) that, in the case of metastatic stage, has a poor prognosis for response to treatment and survival. It is remarkable for its purely hematogenous pattern of dissemination, most commonly to the liver (60%) and lungs (25%). Current approaches using percutaneous hepatic perfusion (PHP) with melphalan resulted in response rates of up to 40% in the liver (1, 2) (for results of our own phase II study see paragraph 6.3.2). However, a main part of the patients developed extrahepatic disease in the follow-up, whereas the liver metastases were mainly stable.

Checkpoint inhibitors have been shown to improve overall survival in metastasized cutaneous melanoma in phase III studies (3-6), but seem to have limited activity as monotherapies in metastasized uveal melanoma (7-9). The combination of ipilimumab and nivolumab has achieved 2 out of 6 patients PR in a retrospective analysis (10). Interestingly, both patients had a liver-directed therapy (SIRT and chemoembolization) before the immunotherapy.

Combination of radio-frequency ablation (RFA) and anti-CTLA-4 enhanced antigen-loading of dendritic cells, and induced long-lasting anti-tumor immune responses in a murine melanoma model without induction of any severe side effects (11, 12). A phase Ib/II trial by Blank et al. (13) showed unconfirmed responses in some patients when RFA was combined with ipilimumab in uveal melanoma, but long-term disease stabilization was not achieved. Most of the responses were seen in extrahepatic metastases. Combining percutaneous hepatic perfusion (PHP) with checkpoint inhibitors could together lead to control of hepatic and extrahepatic disease. Therefore, we propose the current trial: Phase1b/2 Study Combining Hepatic Percutaneous Perfusion with Ipilimumab plus Nivolumab in advanced Uveal Melanoma (CHOPIN).

8. Screening laboratory values must meet the following criteria: WBC = 2.0x109/L, Neutrophils = 1.0x109/L, Platelets = 100 x109/L, Hemoglobin = 6.5 mmol/L, Creatinine = 2x ULN, AST = 2.5 x ULN, ALT = 2.5 x ULN, Total bilirubin = 1.5 X ULN, INR and PTT in normal range, LDH < 2xULN

9. Women of child bearing potential (WOCBP) must agree to use a reliable form of contraceptive as described in paragraph 5.4.

10. Men must agree to the use of male contraception as described in paragraph 5.4.

11. Absence of additional severe and/or uncontrolled concurrent disease

12. No prior, or ongoing other malignancy, except adequately treated basal cell or squamous cell skin cancer, cervical cancer in situ or adequately treated other cancer with eradicative intent for which the patient has been continuously disease-free for > 2 years.

13. No aberrant vascular anatomy of the liver that precludes PHP

Exclusion Criteria:

1. Cerebral or meningeal metastasized uveal melanoma

2. Subjects with any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications, except for subjects with vitiligo or resolved childhood asthma/atopy;

3. Prior immunotherapy (tumor vaccine, cytokine, or growth factor)

4. Known history of infection with Human Immunodeficiency Virus;

5. Active infection requiring therapy, positive serology for Hepatitis B surface antigen or Hepatitis C ribonucleic acid (RNA)

6. History of congestive heart failure, active cardiac conditions, including unstable coronary syndromes (unstable or severe angina, recent myocardial infarction), significant arrhythmias and severe valvular disease must be evaluated for risks of undergoing general anesthesia.

7. History or evidence of clinically significant pulmonary disease e.g. severe COPD that precludes the use of general anesthesia.

8. Underlying medical conditions that, in the Investigator's opinion, will make the administration of study treatment hazardous or obscure the interpretation of toxicity determination or adverse events;

9. Latex allergy, and known hypersensitivity/allergy to ipilimumab, nivolumab, melphalan or heparin

10. Prior Whipple's Surgery

11. Concurrent medical condition requiring the use of immunosuppressive medications, or immunosuppressive doses of systemic or absorbable topical corticosteroids;

13. Patients who are unable to be temporarily removed from chronic anti-coagulation therapy.

14. Patients with active bacterial infections with systemic manifestations (malaise, fever, leucocytosis) are not eligible until completion of appropriate therapy.

15. Use of other investigational drugs before study drug administration for systemic malignancy

16. Pregnancy or nursing
