Dabrafenib and Trametinib Followed by Ipilimumab and Nivolumab or Ipilimumab and Nivolumab Followed by Dabrafenib and Trametinib in Treating Patients With Stage III-IV BRAFV600 Melanoma

Purpose: 

This randomized phase III trial studies how well initial treatment with ipilimumab and nivolumab followed by dabrafenib and trametinib works and compares it to initial treatment with dabrafenib and trametinib followed by ipilimumab and nivolumab in treating patients with stage III-IV melanoma that contains a mutation known as BRAFV600 and cannot be removed by surgery. Ipilimumab and nivolumab may block tumor growth by targeting certain cells. Dabrafenib and trametinib may block tumor growth by targeting the BRAFV600 gene. It is not yet known whether treating patients with ipilimumab and nivolumab followed by dabrafenib and trametinib is more effective than treatment with dabrafenib and trametinib followed by ipilimumab and nivolumab.

  • Patients may have had prior systemic therapy in the adjuvant setting; however this adjuvant treatment must not have included a CTLA4 or PD1 pathway blocking antibody or a BRAF/MEK inhibitor; also, patients may not have had any prior systemic treatment for advanced (measurable metastatic) disease
  • Patients must have discontinued chemotherapy, immunotherapy or other investigational agents used in the adjuvant setting >= 4 weeks prior to entering the study and recovered from adverse events due to those agents; mitomycin and nitrosoureas must have been discontinued at least 6 weeks prior to entering the study; patients must have discontinued radiation therapy >= 2 weeks prior to entering the study and recovered from any adverse events associated with treatment; prior surgery must be >= 4 weeks from registration and patients must be fully recovered from post-surgical complications

  • Total bilirubin =< 1.5 x ULN except subjects with normal direct bilirubin or those with known Gilbert's syndrome
  • Serum lactate dehydrogenase (LDH) < 10 X ULN (patients with LDH > 10 X ULN are felt to have aggressive disease and should be considered for BRAF inhibitor therapy off protocol)
