The objective is to compare efficacy and safety of AB1010 at 3 or 6 mg/kg/day in treatment of patients with mastocytosis with handicap and bearing activating point mutations in the phosphotransferase domain of c-Kit such as the main mutation Asp-816-Val (D816V).

This is an open-label, two-part Phase 2 study investigating CGT9486 for the treatment of patients with Advanced Systemic Mastocytosis (AdvSM), including patients with Aggressive SM (ASM), SM with Associated Hematologic Neoplasm (SM-AHN), and Mast Cell Leukemia (MCL).

There are two parts to this study, including Part I, Dose Optimization, and Part II Expansion. Part II is separated into two stages.

This is a multi-part, randomized, double-blind, placebo-controlled Phase 2 clinical study comparing the safety and efficacy of bezuclastinib (CGT9486) plus best supportive care (BSC) with placebo plus BSC in patients with nonadvanced systemic mastocytosis (NonAdvSM), including indolent systemic mastocytosis and smoldering systemic mastocytosis, whose symptoms are not adequately controlled by BSC. This study will be conducted in three parts. Patients in Parts 1a, 1b and 2 will receive bezuclastinib or placebo, and may roll over onto Part 3 to receive treatment with bezuclastinib.

In Part 1a and 1b of the study, patients with NonAdvSM will be randomly assigned to 1 of 2 dose levels of bezuclastinib plus BSC, or to placebo plus BSC. Upon analysis of the Part 1 data, a dose will be selected for Part 2. In Part 2, patients with NonAdvSM will be randomly assigned to the selected dose of bezuclastinib plus BSC, or to placebo plus BSC.

Patients who complete Part 1 or Part 2 may participate in Part 3 in which all patients will receive bezuclastinib plus BSC.
