Details and patient eligibility

About

Stage 1: To select the optimal dose of naporafenib + trametinib to be studied in Stage 2.

Stage 2: To compare progression free survival (PFS) and overall survival (OS) for patients with NRAS-mutant (NRASm) melanoma who are randomized to receive the combination of naporafenib + trametinib to that of patients who are randomized to physician's choice of therapy (dacarbazine, temozolomide, or trametinib monotherapy).

Full description

SEACRAFT-2 is a global, Phase III, open-label, randomized study to assess the efficacy and safety of naporafenib administered with trametinib compared to physician's choice of therapy (dacarbazine, temozolomide, or trametinib monotherapy) in patients with unresectable or metastatic NRAS mutant melanoma who have progressed on, or are intolerant to, an anti-programmed death-1 ligand 1 (PD 1/L1)-based regimen. The study will consist of 2 stages: dose optimization in Stage 1 and the Phase 3 portion in Stage 2.

A total of approximately 470 eligible patients will be randomized to receive study drug(s) in this study across 2 stages.

Inclusion and exclusion criteria

Key Inclusion Criteria:

  1. Willing and able to provide written informed consent
  2. Age ≥ 18 years
  3. Histologically or cytologically confirmed unresectable or metastatic cutaneous (includes acral) melanoma.
  4. Documentation of an NRAS mutation (tumor tissue or blood) prior to first dose of study drug(s) as determined locally with an analytically validated assay in a certified testing laboratory.
  5. Archival tumor tissue collected within 5 years prior to enrollment must be confirmed to be available at the time of Screening, which may be submitted before or after enrollment for exploratory biomarker analysis.
  6. Must have received an anti-PD-1/L1 based regimen (monotherapy or combination). Patient must have documented disease progression either while receiving therapy or within 12 weeks of last dose of the most recent anti-PD-1/L1 based regimen; the patient is eligible if they have received other therapies between the most recent anti-PD-1/L1 based regimen and enrollment.
  7. ECOG performance status 0, 1 or 2
  8. Presence of at least 1 measurable lesion according to RECIST v1.1
  9. Able to swallow oral medication.

Key Exclusion Criteria:

  1. Patients with uveal or mucosal melanoma
  2. Prior therapy with an ERK-, MEK-, RAF-, or RAS-inhibitor
  3. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug(s) (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection)
  4. History or current evidence of retinal vein occlusion (RVO) or current risk factors for RVO (e.g., uncontrolled glaucoma or ocular hypertension, history of hyperviscosity or hypercoagulability syndrome)
  5. LVEF <50%
  6. Symptomatic CNS metastases that are neurologically unstable. Patients with controlled CNS metastases are eligible.
  7. Patients receiving treatment with herbal medicine known to cause liver toxicity, which cannot be discontinued 7 days prior to first dose of study drug(s) and for the duration of the study.
  8. Are pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the trial
