Phase 1b/2 Study of the Combination of IMCgp100 With Durvalumab and/or Tremelimumab in Cutaneous Melanoma

This study is a Phase Ib/II, multi-center, open-label study of IMCgp100 as a single agent and in combination with durvalumab (MEDI4736) and/or tremelimumab in metastatic cutaneous melanoma. The purpose of this study is to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and to evaluate the anti-tumor activity of IMCgp100 in combination with durvalumab (MEDI4736, programmed death-ligand 1 [PD-L1] inhibitor), tremelimumab (CLTA-4 inhibitor), and the combination of durvalumab with tremelimumab compared to single-agent IMCgp100 alone. The study will enroll patients who have metastatic melanoma that is refractory to treatment with an anti-PD-1 inhibitor in the metastatic setting. This study will also evaluate the safety, tolerability, and anti-tumor activity of IMCgp100 monotherapy in patients with advanced non-uveal melanoma who progressed on prior PD-1 inhibitors approved for the treatment of advanced melanoma; patients with BRAF mutations must be refractory to approved BRAF-based therapy. Recent biologic evidence indicates that optimal responses to programmed cell death-1 (PD-1) directed therapy require the presence of CD8+ T cells in the tumor microenvironment and thus therapies such as IMCgp100 that recruit these effector cells to the tumor may overcome pre-existing resistance to checkpoint blockade. This emerging biology of checkpoint inhibitor resistance suggests the combination of IMCgp100 with checkpoint inhibition may have enhanced activity in patients with pre-existing resistance.

PLX3397 KIT in Acral aNd mucOsal Melanoma

KIT (receptor tyrosine kinase) mutations occur in 15% of acral and mucosal melanomas. PIANO is a single arm, phase II, open-label, multicentre study to evaluate the efficacy and safety (plus molecular basis of such effects) of the KIT inhibitor PLX3397 (developed by Plexxikon) in advanced KIT mutated acral and mucosal melanoma. In this trial a total of 24 patients (9 in the first stage and 15 in the second stage) will receive treatment over a 24 month recruitment period. Following consent and successful screening, patients will receive PLX3397 capsules 1000mg/day as monotherapy, and will remain on therapy as long as they are deriving clinical benefit. Patients will be seen every 4 weeks during treatment to monitor response and toxicity. Routine blood tests will be carried out at all visits and pharmacokinetics/pharmacodynamics sampling (1 x 8 milliliter(ml) whole blood sample) will be done pre-dose on Day 1 and Day 15, frozen and stored locally and sent to Plexxikon's vendor for central analysis at the end of the study. Imaging will be carried out every 12 weeks to monitor response. The first 9 patients will also receive two [18F]-fluorodeoxyglucose (FDG) PET scans (baseline and at Day 15). From specific named participating sites, 12 patients will provide additional (optional) consent to take part in translational research. 5 of these patients will have a fresh tumour biopsy taken at baseline, at day 15 and upon disease progression. The same 5 patients plus an additional 7 patients (to give a total of 12 patients) will also donate blood samples at baseline, 2 weeks, 12 weeks and on disease progression for the evaluation of circulating tumour cells and circulating free tumour DNA. All patients will be followed up every 6 months until death or for 12 months after the last patient has discontinued study treatment.
