Neurofibromatosis Type 2 | Drug: REC-2282 Drug: Placebo | Phase 2 Phase 3 |
This is a parallel-group, two-staged, Phase 2/3, randomized, multi-center study to investigate the efficacy and safety of REC-2282 in patients with progressive NF2 mutated meningiomas, with either NF2 disease-related meningioma or recurrent sporadic meningiomas that have NF2 mutations.
Cohort A will provide early data on efficacy and safety of REC-2282 in participants with progressive NF2 mutated meningiomas, and provide guidance for the dose in the confirmatory part of the study (Cohort B). The purpose of Cohort B of the study is to assess the efficacy and safety of REC-2282 compared with placebo in participants with progressive NF2 mutated meningiomas.
In both cohorts, there will be a screening period of up to 8 weeks, a treatment period, a 4-week safety follow-up period after the end of treatment, and a 6-month post-study follow-up. The first 8 participants enrolled in Cohort A will complete a food effect run-in sub study. At the end of the study period, participants may be offered participation in an open-label extension (OLE) period.
In Cohort A, adult participants will be randomized to one of two dose levels of REC-2282.
In Cohort B, participants will be randomized to REC-2282 treatment (dose to be determined from Cohort A) arm or placebo arm in a ratio of 2:1.
