- Registration Number
- NCT03875079
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This is an open-label, multicenter, Phase Ib study to evaluate the safety and therapeutic activity of RO6874281 in combination with pembrolizumab. The study will consist of 3 parts: a safety run-in (Part I: Cohorts 1.1. and 1.2) and two expansion parts (Parts II and III). Part II will start once all participants in Cohort 1.1 have completed the observation period. Part III will start once all participants in Cohorts 1.1 and 1.2 have completed the observation period.

- Histologically confirmed unresectable stage III or stage IV cutaneous or mucosal melanoma (AJCC v8.0).
- Participants need to have known BRAF status.
- CPI naïve melanoma population: Participants with unresectable stage III or stage IV cutaneous or mucosal melanoma who have not received prior treatment for advanced disease. BRAF mutation-positive patients are eligible without prior treatment or after failure of BRAF directed inhibitor therapy.
- CPI experienced melanoma population: Participants with unresectable stage III or stage IV cutaneous melanoma. Participants must have progressed during or after treatment with anti PD-1 antibody therapy, either as monotherapy or in combination with other agent(s).
- Participants should have adequate cardiovascular, hematological, liver, and renal function.
- Participants with unilateral pleural effusion are eligible if they fulfill both of the following: NYHA Class 1; Forced expiratory volume 1 (FEV1) >70% and forced vital capacity (FVC) >70% of predicted value; participants with lung metastases should present with DLCO >60% of predicted value.

Medical Conditions

-
History of chronic liver disease or evidence of hepatic cirrhosis.
-
Dementia or altered mental status that would prohibit informed consent.
-
History of autoimmune disease.
-
Adverse events related to any previous radiotherapy, chemotherapy, targeted therapy, CPI therapy or surgical procedure that have not resolved to Grade =< 1, except alopecia (any grade) and Grade 2 peripheral neuropathy.
-
History of idiopathic pulmonary fibrosis, pneumonitis (including drug induced), organizing pneumonia (i.e., bronchiolitis obliterans, cryptogenic organizing pneumonia, etc.), or evidence of active pneumonitis on screening chest computed tomography (CT) scan.
-
Bilateral pleural effusion.
-
Severe dyspnea at rest or requiring supplementary oxygen therapy.
-
Concurrent therapy with any other investigational drug (defined as a treatment for which there is currently no regulatory authority approved indication).
-
Immunomodulating agents: Last dose with any of the following agents, for example, etanercept, infliximab, tacrolimus, cyclosporine, mycophenolic acid, alefacept, or efalizumab (or similar agents) < 28 days before study treatment administration. Regular immunosuppressive therapy (i.e., for organ transplantation, chronic rheumatologic disease)
-
Treatment with systemic immunosuppressive medications including, but not limited to prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-TNF agents within 2 weeks prior to Cycle 1 Day 1.
-
Radiotherapy within the last 4 weeks before start of study treatment administration, with the exception of limited field palliative radiotherapy.
-
Administration of a live, attenuated vaccine within 4 weeks before Cycle 1 Day 1.
-
Major surgery or significant traumatic injury < 28 days before study treatment administration (excluding fine needle biopsies) or anticipation of the need for major surgery during study treatment.
-
Known hypersensitivity to any of the components of the RO6874281 drug product or pembrolizumab drug product, including but not limited to hypersensitivity to Chinese Hamster Ovary cell products or other recombinant human or humanized antibodies.
-
No prior cytotoxic therapy for unresectable stage III or stage IV disease is permitted.
-
Toxicity from prior anti-PD-1 antibody therapy (including adjuvant treatment).

Group Intervention Description Part I Safety Run in: RO6874281 + Pembrolizumab Pembrolizumab Cohort 1.1 (CPI naive and experienced melanoma participants): Participants will receive RO6874281 in combination with Pembrolizumab every 3 weeks (Q3W) and will be observed for 2 cycles (ie: 6 weeks) in order to confirm the safety of the proposed dose and schedule that will be used in Part II of this study. Cohort 1.2 (CPI experienced melanoma participants only): Participants will receive RO6874281 in combination with Pembrolizumab via an induction and maintenance schedule for RO6874281: QW three times (D1, D8, D15) followed by Q3W dosing (D22 and subsequent). Pembrolizumab is to be administered Q3W, starting on Day 1. Participants will be observed for 2 pembrolizumab cycles (ie: 6 weeks) in order to confirm the safety of the proposed dose and schedule that will be used in Part III of this study. Part II Expansion: RO6874281 + Pembrolizumab Pembrolizumab Part II will start once all participants in Part I Cohort 1.1 have completed the observation period. Approximately 34 participants will receive RO6874281 in combination with Pembrolizumab every 3 weeks (Q3W) and will be observed for 2 cycles (ie: 6 weeks). Part III Expansion: RO6874281 + Pembrolizumab Pembrolizumab Part III will start once all participants in Part I Cohorts 1.1 and 1.2 have completed the observation period. Approximately 80 participants will be randomised to receive RO6874281 in combination with Pembrolizumab in either a Q3W or QW/Q3W schedule. Part III Expansion: RO6874281 + Pembrolizumab RO6874281 Part III will start once all participants in Part I Cohorts 1.1 and 1.2 have completed the observation period.
