- Duration: Patients were treated for 12 cycles, with an option to switch from placebo to Koselugo after cycle 12.
- Efficacy and Safety:
- Efficacy: The approval is based on the KOMET trial results, which indicate a meaningful reduction in tumor size.
- Safety: The safety profile of Koselugo was consistent with its established use in pediatric patients, suggesting that it is well-tolerated in adults.
- Clinical Context:
- Condition: NF1 is a rare genetic disorder that can lead to significant health complications, including the growth of non-malignant tumors (plexiform neurofibromas) that can affect various organ systems.
- Impact: Up to 50% of individuals with NF1 may develop plexiform neurofibromas, leading to debilitating symptoms such as pain and disfigurement.
