Efficacy and Safety of REC-2282 in Patients With Progressive Neurofibromatosis Type 2 (NF2) Mutated Meningiomas
This study will investigate the efficacy and safety of REC-2282 in patients with progressive NF2 mutated meningiomas who have either NF2 disease-related meningioma or recurrent sporadic meningiomas that have NF2 mutations. This study is a parallel-group, two-staged, Phase 2/3, randomized, multi-center study with two cohorts: Cohort A followed by Cohort B. The purpose of Cohort A is to provide early data on efficacy and safety of REC-2282 in participants with progressive NF2 mutated meningiomas, and provide guidance for the correct dose, population, sample size, and endpoint for the confirmatory part of the study (Cohort B). Additional goals for Cohort A are to assess effects of food on drug absorption. 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.
• ≥12 years of age and weighing at least 40 kg
• Progressive meningioma that is amenable to volumetric analysis
• Has either 1) sporadic meningioma with confirmed NF2 mutation; or, 2) confirmed diagnosis of NF2 disease (revised Manchester criteria); or, 3) at least one NF2-related tumor (with pathogenic germline or proven mosaic NF2 variant)
• Adequate bone marrow function
• Has provided written informed consent/assent to participate in the study
• Progressive disease associated with significant or disabling clinical symptoms likely to require surgery or radiation therapy within the next 3 months.
• Received prior surgery, radiosurgery, or laser interstitial thermal therapy in the target tumor, or immediately adjacent to the target tumor within 6 months prior to screening.
• Received an anti- tumor agent for meningioma within 3 months, or 5 half-lives (whichever is longer), prior to screening.
• History of an active malignancy within the previous 3 years except for localized cancers that are considered cured, and, in the opinion of the investigator, present a low risk of recurrence.
• Received another investigational drug within 30 days prior to screening
• Pregnant, lactating, or is planning to attempt to become pregnant or impregnate someone during this study or within 90 days after the last dose of IMP.
