Brief Summary

This study is a Phase I clinical trial to evaluate the tolerability and pharmacokinetics of TQ-B3234 capsules in Chinese subjects associated with neurofibromatosis type I (neurofibroma and peripheral malignant neurilemmoma).

Two study phases were designed, including (1) dose escalation and (2) cohort expansion.

The purpose of this study was to evaluate the tolerance, pharmacokinetic characteristics, efficacy and safety of TQ-B3234 capsule, and to explore the therapeutic biomarkers related to this product.

Conditions

Type I Neurofibromatosis

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

TQ-B3234 capsule

In the dose escalation phase, enrolled subjects first received a single dose on an empty stomach for a 3-day observation period. If Dose limiting toxicity (DLT) did not occur, continuous multiple doses were continued, once a day on an empty stomach for a treatment cycle of 28 days.

After the dose escalation phase was completed, cohort extension studies were conducted according to the identified phase ii clinical recommended doses.type I neurofibromatosis （NF1） patients and malignant peripheral nerve sheath tumors （MPNST） patients were selected.

Group Type: EXPERIMENTAL

TQ-B3234 capsule

Intervention Type: DRUG
