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.


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.

Yes No Not Sure

Inclusion Criteria

Histologic diagnosis Patients with recurrent/progressive high-grade gliomas, as defined by progressive neurologic abnormalities or worsening neurologic status not explained by causes unrelated to tumor progression (e.g., anticonvulsant or corticosteroid wean, electrolyte disturbances, sepsis, hyperglycemia, etc.), OR a 25% increase in the bi-dimensional measurement, taking as a reference the smallest disease measurement recorded since diagnosis utilizing the MRI sequence best demonstrating tumor, OR the appearance of a new/metastatic tumor lesion since diagnosis
Eligible diagnoses include but are not limited to the following: diffuse intrinsic pontine glioma (DIPG), H3K27M-mutant diffuse midline glioma (DMG), glioblastoma multiforme, anaplastic astrocytoma and anaplastic oligodendroglioma. Spinal cord tumors are eligible with pathologic confirmation of the above
Please note: patients with a radiographically typical DIPG at diagnosis, defined as a tumor with a pontine epicenter and diffuse involvement of more than 2/3 of the pons, are eligible without histologic confirmation
Patients with pontine lesions that do not meet these radiographic criteria will be eligible if there is histologic confirmation of pontine glioma WHO II-IV
Patients with diffuse or multi-focal disease are eligible; patients with leptomeningeal spread are eligible
Age Patient must be 3 but 21 years of age at the time of enrollment
BSA Patients must have a BSA 0.70-2.50 m2 for dose 120 mg/m2/dose BID. Patients must have a BSA 0.55-2.80 m2 for dose 80 mg/m2/dose BID (Patients who have BSA 0.55-1.00 m2 will only receive 100 mg AM dose)
Ability to Swallow Patient must be able to swallow tablets whole
Measurable disease Patient must have measurable disease in two dimensions on MRI to be eligible
Prior Therapy Patients must have recovered from the acute treatment-related toxicities (defined as < grade 1) of all prior chemotherapy, immunotherapy, or radiotherapy prior to enrollment on this study
Chemotherapy Patients must have received their last dose of known
myelosuppressive anticancer therapy at least 21 days prior to enrollment or at
least 42 days if nitrosourea
Investigational/ Biologic Agent
Biologic or investigational agent (anti-neoplastic): Patient must have
recovered from any acute toxicity potentially related to the agent and
received their last dose of the investigational or biologic agent 7 days prior
to study enrollment
For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur
Monoclonal antibody treatment and agents with known prolonged half-lives
Patient must have recovered from any acute toxicity potentially related to the
agent and received their last dose of the agent 28 days prior to study
Immunotherapies: Patients who have received checkpoint inhibitors or other
immunotherapies with a known potential for pseudoprogression and who have
assumed tumor progression must be at least 3 months from prior immunotherapy
AND have at least two MRI scans at least 4 weeks apart demonstrating further
progression OR have a biopsy to confirm tumor progression OR have new site(s)
