Interleukin-6 Receptor Inhibitor Sarilumab in Combination With Ipilimumab, Nivolumab and Relatlimab in Patients With Unresectable Stage III or Stage IV Melanoma

Overview

The study will evaluate how safe the study drug is, how well you tolerate it, and how it works in the body and the disease's response to the drug. The study drug being tested is sarilumab, when given with the combination of ipilimumab, nivolumab, and relatlimab in patients with stage III or stage IV melanoma that cannot be removed by surgery. Previous studies have provided a strong rationale for combining sarilumab, with ipilimumab, nivolumab and relatlimab in metastatic melanoma to reduce side effects and potentially work better for this type of cancer. Sarilumab is an FDA-approved inhibitor of the receptor for the cytokine IL-6, currently approved for the treatment of rheumatoid arthritis, but it is not FDA-approved to treat melanoma. This means that the use of Sarilumab to treat melanoma is considered investigational. The other drugs which will be administered in this study, ipilimumab and nivolumab, are also monoclonal antibodies, but they target different proteins. Ipilimumab and nivolumab are both approved by the FDA to treat advanced stage III and IV melanomas. The nivolumab + relatlimab FDC (fixed dose combination) being used in this study is considered investigational, meaning it is not approved by the FDA.

Detailed Description

In this Phase II, open-label study, the treatment period will consist of an induction phase and a maintenance phase. The induction phase consists of an induction treatment cycle of 8 weeks which is the DLT period. The maintenance phase consists of treatment cycles of 56 days (8 weeks) each, and may extend up to 2 years. During the induction phase, ipilimumab will be administered on day 1 at a dose of 1 mg/kg intravenously (IV) during the 8-week induction period, concurrent with nivolumab 480 mg/relatlimab at 160 mg, fixed dose, administered at a 4 week interval on days 1 and 29 with a 30 minute rest period between the two infusions on day 1 and 29. On days administered in combination, nivolumab/relatlimab will be administered first at a dose of 480 mg/160 mg, followed by ipilimumab at 1 mg/kg, and immediately followed by sarilumab at 150 mg given subcutaneously. Nivolumab/relatlimab and ipilimumab will be each administered IV over 30 minutes consecutively with a 30-minute rest period between infusions, on day 1 of the first and all subsequent 56-day maintenance treatment cycles and nivolumab/relatlimab will be administered on day 29 of each cycle. Sarilumab will be administered subcutaneously every 2 weeks during the 56-day induction treatment cycle and the first two 56-day maintenance cycles only for a total of 24 weeks

It is formulated at a concentration of 5 mg/mL ipilimumab in TRIS hydrochloride (also known as 2-amino-2-hydroxymethyl-1,3-propanediol hydrochloride), sodium chloride, mannitol, pentetic acid (also known as diethylenetriaminepentaacetic acid or DTPA), polysorbate 80, and water at pH 7.0. Sodium hydroxide and/or hydrochloric acid may be used to adjust the pH of the solution. Ipilimumab Injection 200 mg/40 mL (5 mg/mL) is packaged in a 50-cc Type I flint molded glass vials.
  • Drug: Nivolumab/Relatlimab
    • The FDC drug product, referred to as nivolumab/relatlimab, contains relatlimab and nivolumab in a single vial in a kit of 2 vials. The product is a sterile, non-pyrogenic, single-use, isotonic aqueous solution for IV infusion. It is formulated at a total protein concentration of 16 mg/mL (4 mg/mL relatlimab and 12 mg/mL nivolumab) and is packaged in a 20-cc glass vial in a kit of two vials. Each vial contains 80 mg of relatlimab and 240 mg of nivolumab.

    • Time Frame: week 24 (+/- 7 days)
    • Each patient will be assigned one of the following categories: = Complete Response (CR) = Disappearance of all target lesions; = Partial Response (PR) = At least a 30% decrease in the sum of the longest diameter (LD) of target lesions. = Stable Disease (SD) = Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum LD since treatment started. = Progressive Disease (PD) = At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. = Early death from malignant disease = Early death from toxicity = early death because of other cause 9 = Unknown (not assessable, insufficient data)

Secondary Measures

  • Progression-free survival (PFS)

    • Overall Survival will be reported as the time from first dosing to death due to any cause. If a patient has not died at the time of analysis, OS will be censored as of their last known date alive (i.e., last time patient was contacted for any reason in the study). Patients who do not have any tumor assessment on treatment will be followed up for OS, and their date of death will be incorporated into the OS analysis.
