Summary

This study aims to demonstrate that in subjects with symptomatic, inoperable plexiform neurofibromas associated with neurofibromatosis type 1, TQ-B3234 capsules significantly improve the objective response rate at Week 24 compared to placebo.

Conditions

  • Plexiform Neurofibroma

Interventions

DRUG

TQ-B3234 capsules

TQ-B3234 is an antitumor molecular targeted drug, a selective mitogen-activated protein kinase 1 and 2 (MEK1/2) inhibitor. It primarily inhibits the mitogen-activated protein kinase (MEK) protein (an upstream regulator of the extracellular signal-regulated kinase (ERK) pathway), thereby affecting the mitogen-activated protein kinase (MAPK) pathway and suppressing cell proliferation. MEK inhibitors are recognized to play a significant role in the pathogenesis of plexiform neurofibromas associated with neurofibromatosis type 1.

DRUG

TQ-B3234 placebo

TQ-B3234 placebo without drug substance.
