Summary
This is a patient oriented translational research project aiming to improve clinical outcomes for patients with BRAF and NRAS wild-type unresectable Stage III or Stage IV metastatic melanoma who have progressed on, or are unable to receive standard therapy (in general, immunotherapy). Consecutive patients seen at three major clinics and fitting the broad eligibility criteria will be invited to participate.
The approach is designed to test the impact of different targeted drugs on different mutations in a single type of cancer. In this project, patients will have tumour tissue genetically profiled to determine which mutation(s) are present, and will then be assigned to receive a matched drug expected to target the mutation(s) in the tumour. Where multiple targets are identified in one patient, or where multiple potential therapies would be appropriate for a single tumour mutation, the treating clinician may determine the appropriate therapeutic approach after consultation with the study team, using the latest version of library of matched therapies.
Description
Current standard of care testing covers mutations in the BRAF and NRAS genes. The comprehensive gene testing platform to be used in this project is designed to interrogate the entire coding sequence of 315 cancer-related genes plus introns from 28 genes often rearranged or altered in cancer. These genes are known to be somatically altered in solid cancers based on recent scientific and clinical literature. The test panel will be used on melanoma tissue from patients pre-screened as having BRAF and NRAS wild-type melanoma. The extent of testing will be updated to reflect new discoveries in melanoma tumourigenesis and availability of new therapies as the project proceeds. Testing will be performed on formalin-fixed and paraffin-embedded samples of metastatic tissue. Archival tissue from primary or regional recurrent melanoma may be considered if no recent sample is available or possible.
All new patients with unresectable Stage III or IV melanoma seen at each participating site will be invited to participate. Following written consent, all patients will undergo the standard testing for BRAF and NRAS mutations. Patients found to have mutations in either gene will receive standard treatment with dabrafenib and / or trametinib and no further molecular testing.
Patients with wild type versions of BRAF and NRAS genes will have tumour tissue sent for the extended gene testing platform. These patients will first receive standard of care therapy for wild type BRAF / NRAS melanoma, where possible. Once standard therapies have been exhausted (because of disease progression or intolerable adverse events), patients will then receive a targeted therapy matched for their genetic result, if applicable. The selection of targeted therapy will be based on clinical evidence of activity in other solid tumours harbouring similar mutations and / or in at least Phase I testing in melanoma. The table of matched therapies will be modified and extended as new findings from clinical research become available. Patients may be included in specific clinical trials of targeted therapies if available, e.g. a MEK inhibitor combined with an MDM2 inhibitor (AMG232) for BRAF and TP53 wild-type melanoma or a MEK inhibitor combined with a CDK4/6 inhibitor for BRAF wild-type melanoma.
The extensive molecular profiling platform is fully validated and will be conducted by an external provider accredited by an authority with the responsibility to award Laboratory Accreditation at private and public facilities.
