PAS-004 for Plexiform Neurofibromas in NF1

This study is testing a new oral medication called PAS-004 in adults with Neurofibromatosis Type 1 (NF1) who have plexiform neurofibromas (tumors that grow along nerves). PAS-004 is a MEK 1/2 inhibitor, which means it blocks certain proteins involved in cell growth. The main goals are to understand how safe PAS-004 is at different doses and what side effects it might cause. The study has two parts: Part A will help determine safe doses, and Part B will test those doses further. We are looking for 56 participants for this study, but the current recruitment status is unclear.

Study design
This is an interventional study with a planned enrollment of 56 participants. It is structured in two parts to evaluate safety and tolerability.
What's involved
Participants will take PAS-004 tablets once daily. Part A involves one 28-day treatment cycle, while Part B involves six 28-day treatment cycles.
Compensation
Not stated in the trial record.
Follow-up
Safety and tolerability will be measured through Day 28 for Part A and through Day 168 for Part B.
