Design
Allocation: N/AIntervention Model: Single Group AssignmentIntervention Model Description: This is a phase I study and we will use a design similar to the Rolling-6 design and open 6 slots initially on Dose level 1. If we observe no-more than 1 DLT in these 6 subjects then we would expand this cohort to at least 12 patients for PK and additional safety information. If more than 1 DLT is observed on dose level 1 in 2-6 subjects, then further enrollment to dose level 1 will stop, the dose will be de-escalated to dose level 0 and the same approach will be repeated. Based on the above-outlined de-escalation rules, if dose level 0 is found to be too toxic, then the trial will be closed to accrual and the merits of amending or closing the trial permanently will be reconsidered.Masking: None (Open Label)Primary Purpose: Treatment

INCB7839 is an inhibitor of the ADAM (A Disintegrin and Metalloprotease) 10 and 17 proteases. Neuronal activity regulates glioma growth through neuroligin-3 (NLGN3). ADAM 10 is the protease responsible for NLGN3 release into the tumor microenvironment and represents a promising therapeutic target. Pre-clinical studies of INCB7839 in patient-derived pediatric high-grade gliomas (GBM and DIPG) revealed that INCB7839 inhibits pediatric high- grade glioma growth and improves overall survival. In vivo testing also demonstrated that INCB7839 penetrates brain tissue sufficient to achieve its pharmacodynamic effect of ADAM10 inhibition. Further pre-clinical studies in other animals revealed minimal toxicity, including non-adverse to mild increases in serum hepatobiliary enzymes, protein, calcium, cholesterol values, along with minimal decreases in RBC mass parameters; all parameters recovered. INCB7839 has been evaluated in Phase I and Phase II clinical trials for previously treated solid tumors and breast cancer. Of the adverse events (AEs) noted, the majority were mild-to-moderate in severity, the most frequent being fatigue, nausea, anorexia, diarrhea, emesis, abdominal pain, anemia and constipation. The dose-limiting toxicity for monotherapy with INCB7839 in Phase I clinical trials was declared to be deep venous thrombosis (DVT). Out of 41 patients, there was a total of 9 thrombotic events including mild superficial thrombophlebitis (n=1), DVT (n=4), vena cava thrombosis with renal insufficiency in a patient with squamous cell cancer of the head and neck (n=1), atrial thrombosis in patient with breast cancer (n=1), and pulmonary embolism in patients with hormone-refractory prostate cancer (n=2). Overall, INCB7839 does exhibit a pro-coagulant effect in some adult patients, resulting in an increased incidence of DVT, whether used alone or in combination. The mechanism of this effect is unknown, and there is no clear relationship between the frequency of thrombosis and the dose administered.
