E.2.1 | Main objective of the trial |
1) To evaluate the progression-free-survival (PFS) in patients with ipilimumab refractory advanced MEL receiving either MK-3475 or chemotherapy.
Hypothesis: Administration of MK-3475 will result in a clinically meaningful improvement in PFS versus treatment with chemotherapy.
2) To evaluate the overall survival (OS) in patients with ipilimumab refractory advanced MEL receiving either MK-3475 or chemotherapy.
Hypothesis: Administration of MK-3475 will result in a clinically meaningful improvement in OS versus treatment with chemotherapy.
|
|
E.2.2 | Secondary objectives of the trial |
1) To evaluate the overall response rate (ORR) in patients with ipilimumab refractory advanced MEL receiving either MK-3475 or chemotherapy.
Hypothesis: Administration of MK-3475 will result in a clinically meaningful improvement in ORR versus treatment with chemotherapy.
2) To evaluate the response duration in patients with ipilimumab refractory advanced MEL receiving either MK-3475 or chemotherapy.
3) To evaluate OS, PFS, and ORR in the biomarker positive subgroup defined by PD-L1 expression level (cutoff point to be estimated from external data) receiving either MK-3475 or chemotherapy.
4) To further characterize the PK profile of single agent MK-3475 at 2 mg/kg and 10 mg/kg.
5) To evaluate safety, tolerability and adverse experience profile of single agent MK-3475 2 mg/kg and 10 mg/kg.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) Patient must have a histologically or cytologically confirmed diagnosis of unresectable stage III or metastatic MEL not amenable to local therapy.
• Patient may not have a diagnosis of uveal melanoma
2) Patients must be refractory to ipilimumab, defined as (patients must meet all of the following criteria):
• Received at least two doses of ipilimumab (minimum dose of 3 mg/kg given every 3 weeks)
• Progressive disease (PD) after ipilimumab will be defined according to irRC (Appendix 6.6). The initial evidence of PD is to be confirmed by a second assessment, no less than four weeks from the date of the first documented PD, in the absence of rapid clinical progression (this determination is made by investigator; SPONSOR will collect imaging scans for retrospective analysis). Once PD is confirmed, initial date of PD documentation will be considered the date of disease progression.
• Documented disease progression within 24 weeks of the last dose of ipilimumab. Patients who were re-treated with ipilimumab and patients who were on maintenance ipilimumab will be allowed to enter the trial as long as there is documented PD within 24 weeks of the last treatment date (with ipilimumab).
• Ipilimumab does not need to be the last treatment prior to entering current trial as long as the patient meets the above described criteria
3) Resolution/improvement of ipilimumab-related AEs (including irAEs) back to Grade 0-1 and ≤10 mg/day prednisone (or equivalent dose) for irAEs for at least two weeks prior to first dose of study drug.
• No history of CTCAE Grade 4 irAEs from ipilimumab
• No history of CTCAE Grade 3 requiring steroid treatment (>10 mg/day prednisone or equivalent dose) >12 weeks
• Minimum of four weeks (wash out period) from the last dose of ipilimumab
4) Patients must consent to provide a newly obtained tumor tissue/biopsy (or specimen obtained within 60 days prior to consenting) for biomarker analysis from a core or excisional biopsy of a tumor lesion not previously irradiated.
• The patient must be able to undergo tumor biopsy
• If a newly obtained biopsy is not feasible, the patient requires sponsor approval to be eligible
5) BRAF V600E or V600K mutation status must be known at Screening. Patient with BRAF mutant melanoma must have had a prior treatment regimen that included vemurafenib, dabrafenib, or an approved BRAF and/or MEK inhibitor.
6) Patient must have at least one radiologically measurable lesion as per RECIST 1.1 (Appendix 6.1) defined as a lesion that is 10mm in longest diameter or lymph node that is 15mm in short axis imaged by CT scan or MRI.
7) Patient is ≥18 years of age on day of signing informed consent.
8) Patient must have a performance status of 0 or 1 on the ECOG Performance Scale (Appendix 6.4).

|
E.4 | Principal exclusion criteria |
1) Patient who has had chemotherapy, radioactive, or biological cancer therapy within four weeks prior to the first dose of study drug, or who has not recovered to CTCAE Grade 1 or better from the AEs due to cancer therapeutics administered more than four weeks earlier.
• The requirements for prior ipilimumab treatment are listed in Inclusion Criterion 2
2) Patient who received ipilimumab only as an adjuvant therapy.
3) Patient is currently participating or has participated in a study of an investigational agent or using an investigational device within 30 days of the first dose of study drug.
4) Patient is expected to require any other form of systemic or localized antineoplastic therapy while on study.
5) Patient is on chronic systemic steroid therapy (>10 mg/day prednisone or equivalent) within two weeks before the planned date for first dose randomized treatment or on any other form of immunosuppressive medication. (Patients that are expected to require premedication with corticosteroid for MK-3475 will not be eligible for this study.)
6) Patient has a known history of a hematologic malignancy, primary brain tumor or sarcoma, or of another primary solid tumor, unless the patient has undergone potentially curative therapy with no evidence of that disease for five years.
• The time requirement for no evidence of disease for five years does not apply to the tumor for which a patient is enrolled in the study. The time requirement also does not apply to patients who underwent successful definitive resection of basal or squamous cell carcinoma of the skin, superficial bladder cancer, in situ cervical cancer, breast cancer, or other in situ cancers.
7) Patient has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they meet the following criteria:
• Inactive (without evidence of progression which is documented by CT or MRI within 4 weeks prior to the planned study treatment date), and
• On ≤10 mg/day prednisone or equivalent for at least two weeks prior to the planned study treatment date
8) Patient previously had a severe hypersensitivity reaction to treatment with another mAb.
9) Patient has an active autoimmune disease or a history of autoimmune disease or syndrome that requires systemic steroids or immunosuppressive agents. Patients with vitiligo or resolved childhood asthma/atopy would be exception to this rule. Patients that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Patients with hypothyroidism stable on hormone replacement will not be excluded from the study.
10) Patients who received treatment with live vaccines within 30 days prior to the first dose of study medication. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, seasonal flu, H1N1 flu, rabies, BCG, and typhoid vaccine.
11) Patient had prior treatment with any other anti-PD-1, or PD-L1 or PD-L2 agent.
• Examples of PD-1 inhibitors (include, but are not limited to): MK-3475 (Merck); Nivolumab (also known as BMS-936558, MDX-1106, ONO-4538) (Bristol-Myers Squibb); Pidilizumab (CT-11) (Cure-Tech/Teva); and AMP-224 (Amplimmune)
• Examples of PD-L1 inhibitors (include, but are not limited to): BMS-936559 (also known as MDX-1105) (Bristol-Myers Squibb); MPDL3280A (also known as RG7446) (Roche Genentech); and MEDI4736 (MedImmune)
• Patients who have received carboplatin plus paclitaxel, paclitaxel alone, DTIC, or temozolomide for MEL prior to randomization will not be eligible to receive the same chemotherapy as study medication. Patients who received DTIC are not eligible to receive temozolomide (and vice versa). Patients who received carboplatin plus paclitaxel are not eligible to receive paclitaxel monotherapy. Patients who received abraxane are not eligible to receive paclitaxel.
12) Patient has previously participated in Merck MK-3475 clinical trials.
