This is a Phase 1/2, open-label, non-randomized, 4-part Phase 1 trial to determine the safety
profile and identify the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D)
of INBRX 106 administered as a single agent or in combination with the anti-PD-1 checkpoint
inhibitor (CPI) pembrolizumab (Keytruda).

This phase III trial compares the effect of adding chemotherapy (doxorubicin or epirubicin hydrochloride [epirubicin] with ifosfamide or dacarbazine) before standard surgery versus surgery alone in improving long-term survival in patients with retroperitoneal sarcomas that are able to be removed by surgery (resectable). Chemotherapy drugs, such as doxorubicin, epirubicin, ifosfamide, and dacarbazine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before surgery may make the tumor smaller and easier to remove and may increase patient survival, compared to surgery alone.

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.
