Basic Information

• Recruitment Status: ACTIVE_NOT_RECRUITING
• Clinical Phase: PHASE1
• Total Enrollment: 99 participants

• Study Start Date: 2021-05-13
• Study Completion Date: 2024-12-31

Brief Summary

This study is being done to evaluate the Tolerability、Pharmacokinetics and Preliminary antitumor activity of oral FCN-338 for the treatment of patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), who have failed or are intolerant to one or more lines of established therapy or for whom no other treatment options are available.

Detailed Description

This is a multicenter, open-label, Phase I dose escalation study of Tolerability、Pharmacokinetics and Preliminary antitumor activity of FCN-338 in ascending cohorts to determine the MTD or recommended dose in patients with relapsed or refractory CLL/SLL patients. This is to be followed by a cohort expansion phase at the MTD or recommended oral dose.

Conditions

Chronic Lymphocytic Leukemia; Small Lymphocytic Lymphoma

Study Design

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

Study Groups

Dose Escalation and Expansion

FCN-338 will be given orally in ascending doses in patients with relapsed or refractory CLL/SLL , until the maximum tolerated dose or recommended dose is reached. Followed by up to 43 patients enrolled in the expansion cohort at the recommended dose.

Group Type: EXPERIMENTAL

FCN-338

Intervention Type: DRUG

FCN-338 will be given orally in ascending doses starting at 50 mg QD until the maximum tolerated dose or recommended dose is reached.
