A Study of Olverembatinib in SDH-deficient GIST.

Официальное название

A Single-Arm Registrational Phase III Study of Olverembatinib in the Treatment of Patients With SDH-Deficient Gastrointestinal Stromal Tumor (POLARIS-3)

Обзор

An international multicenter, open, single-arm pivotal registration phase III study to determine the efficacy and safety of olverembatinib in patients with SDH-deficient gastrointestinal stromal tumor (GIST) who have previously been treated with one-line therapy, and to evaluate the progression-free survival and clinical benefit rate of olverembatinib in patients with SDH-deficient GIST.

Подробное описание

This study intends to enroll patients with SDH-deficient GIST who have failed at least one systemic therapy to receive olverembatinib tablets 40mg orally administered with meals once every other day and every 28 days for a dosing cycle.

Вмешательства

• Препарат Olverembatinib
  Oral administration with meal, QOD, every 28 days for a cycle.

Первичные конечные точки

• Progression-free survival(PFS) rate [Срок оценки: 36 months]

Вторичные конечные точки (2)

• Plasma concentrations of olverembatinib [Срок оценки: Cycle 2 to Cycle 3 (each cycle is 28 days)]
• Number of participants with treatment-related adverse events as assessed by CTCAE v5.0. [Срок оценки: Through study completion,an average of 2 years.]
