MEKTOVI® for the Treatment of Pediatric Adamantinomatous Craniopharyngioma
Study Details
Study Description
Brief Summary
MEKTOVI (binimetinib) is an oral, highly selective reversible inhibitor of mitogen-activated extracellular signal regulated kinase 1 (MEK1) and MEK2. The biological activity of binimetinib that has been evaluated bith in vitro and in vivo in a wide variety of tumor types In this Phase II, the drug will be used to treat pediatric patients diagnosed with recurrent Adamantinomatous Craniopharyngioma including patients who have undergone surgery and/or radiation therapy.

Detailed Description
Adamantinomatous Craniopharyngioma (ACP) is a highly debilitating pediatric brain tumor that lacks medical anti-tumor therapies. Current therapy, which depends largely on surgery and radiation, is associated with poor quality of life and becomes more challenging and risky in the setting of recurrent disease. Recent discoveries regarding the biological characteristics of ACP indicate that available agents, including Mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway inhibitors may have efficacy in the control of ACP. Binimetinib is one such agent.
In this study, up to 38 patients will receive oral binimetinib at the recommended phase 2 pediatric dose (RP2D) of 32 mg/m2 PO every 12 hours for 4 weeks which represents one cycle. Cycles will last 28 days and treatment may continue for up to two years (26 cycles).
It will be a multi-center Phase 2 trial with two strata for patients aged >1 year and <25 years with measurable ACP who may have been previously treated with radiation (Stratum 1, 18 patients) or without radiation (Stratum 2, 18 patients).
