Title: A Phase II, Randomised, Open Label Study of Neoadjuvant Dabrafenib, Trametinib and / or Pembrolizumab in BRAF V600 Mutant Resectable Stage IIIB/C Melanoma
Brief Summary: This study aims to determine which of 3 drug combinations best reduces the size of tumour prior to surgery for advanced melanoma and prevents the recurrence of melanoma after surgery.


Options:
A: Inclusion Criteria:

* ≥18 years of age
* Written informed consent.
* Histologically confirmed, resectable American Joint Committee on Cancer (AJCC, 8th edition) stage IIIB, IIIC (Tx, T0, T1-4, N1b, N2b, N3b, M0) cutaneous melanoma or unknown primary melanoma with sufficient cutaneous and/or nodal disease to enable multiple excisional or core biopsies (at baseline, week 1 and week 2). 'Resectable' tumours are defined as having no significant vascular, central nervous system or bony involvement. Only cases where a complete surgical resection with tumour-free margins can safely be achieved are defined as resectable. Patients who may not have sufficient disease to enable multiple biopsies at weeks 1 and 2 will not be excluded, however the intention of the study is that at least one biopsy at these time points is required.
* Measurable disease according to RECIST version 1.1 criteria (≥ 10mm longest diameter for non-nodal lesions and / or ≥ 15mm in shortest diameter for lymph nodes) within 4 weeks of randomisation. 'Measurable' disease may be ascertained by CT or for cutaneous and superficial lesions, by caliper measurement with digital photography. CT preferred for all lesions where possible. PET imaging will be performed, but not used for the primary purpose of measuring response.
* BRAF V600 mutation positive on immunohistochemistry or a local molecular test (e.g. Oncofocus): a. A positive V600E immunohistochemistry stain at study entry should be formally quantified with a local molecular test following study entry (e.g. Oncofocus); b. Molecular BRAF mutation status should preferentially be confirmed using tissue taken from the presenting stage III / IV disease. Alternatively, archival primary tissue is also acceptable to confirm BRAF mutation status.
* Able to swallow and retain oral medication
* Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
* Demonstrated adequate organ function as defined:

  1. Absolute neutrophil count (ANC) ≥1.5 109/L
  2. Platelets ≥100 109/L

  4. Serum creatinine OR measured or calculated creatinine clearance (CrCl) (Glomerular filtration rate \[GFR\] can also be used in place of creatinine or CrCl) ≤1.5 X upper limit of normal (ULN) OR ≥60 mL/min for patient with creatinine levels \> 1.5 X institutional ULN.
  5. Serum total bilirubin ≤ 1.5 X ULN OR Direct bilirubin ≤ ULN for patients with total bilirubin levels \> 1.5 ULN.
