Mücərrəd

This is a multicenter phase 1 trial of INCB7839 for children with recurrent or progressive high-grade gliomas, including, but not limited to, diffuse intrinsic pontine glioma (DIPG) and other diffuse midline gliomas (DMGs), after upfront therapy.

Təsvir

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.

INCB7839 dosing will begin at 120 mg/m2/dose BID which is equivalent to the adult RP2D (200 mg PO BID) based on a typical adult size of 1.67m2. The INCB7839 dose may be decreased to 80 mg/m2/dose BID if the staring dose is not tolerable. 28 consecutive days (4 weeks) will constitute one course. Patients may continue to receive INCB7839 for 26 courses (approximately 2 years).
