This is a Phase 3, open-label, international, multicenter study of CGT9486 in combination
with sunitinib. This is a multi-part study that will enroll approximately 426 patients. Part
1 consists of two evaluations: 1) confirming the dose of an updated formulation of CGT9486 to
be used in subsequent parts in approximately 20 patients who have received at least one prior
line of therapy for GIST and 2) evaluating for drug-drug interactions between CGT9486 and
sunitinib in approximately 18 patients who have received at least two prior tyrosine kinase
inhibitors (TKIs) for GISTs. The second part of the study will enroll approximately 388
patients who are intolerant to, or who failed prior treatment with imatinib only and will
compare the efficacy of CGT9486 plus sunitinib to sunitinib alone with patients being
randomized in a 1:1 manner.

This phase II trial tests whether using genetic testing of tumor tissue to select the optimal treatment regimen works in treating patients with clear cell renal cell (kidney) cancer that has spread to other places in the body (advanced or metastatic). The current Food and Drug Administration (FDA)-approved regimens for advanced kidney cancer fall into two categories. One treatment combination includes two immunotherapy drugs (nivolumab plus ipilimumab), which are delivered by separate intravenous infusions into a vein. The other combination is one immunotherapy drug (nivolumab infusion) plus an oral pill taken by mouth (cabozantinib). Nivolumab and ipilimumab are immunotherapies which release the brakes of the immune system, thus allowing the patient's own immune system to better kill cancer cells. Cabozantinib is a targeted therapy specifically designed to block certain biological mechanisms needed for growth of cancer cells. In kidney cancer, cabozantinib blocks a tumors blood supply. The genetic (DNA) makeup of the tumor may affect how well it responds to therapy. Testing the makeup (genes) of the tumor, may help match a treatment (from one of the above two treatment options) to the specific cancer and increase the chance that the disease will respond to treatment. The purpose of this study is to learn if genetic testing of tumor tissue may help doctors select the optimal treatment regimen to which advanced kidney cancer is more likely to respond.
