Therapeutic Strategy Summary
The primary therapeutic approach for NF1-related tumors targets the RAS-MAPK pathway downstream of NF1 loss:
- MEK inhibitors (Selumetinib, Trametinib, Mirdametinib, Binimetinib) - Most clinically advanced
- mTOR inhibitors (Sirolimus, Everolimus)
- Multi-kinase inhibitors (Sunitinib, Cabozantinib)
