Study of TL-895 in Subjects With Myelofibrosis

NCT04655118

Description:

This study evaluates TL-895, a potent, orally-available and highly selective irreversible tyrosine kinase inhibitor for the treatment of Myelofibrosis. Participants must be relapsed/refractory (e.g., having failed prior therapy), intolerant, or ineligible to receive JAKi treatment.

Measure:Key Secondary Objective: To determine the duration of response (DOR).
Time Frame:44 months
Safety Issue:
Description:Time from initial response to progression.
Measure:Key Secondary Objective: To determine the progression-free survival (PFS).
Time Frame:44 months
Safety Issue:
Description:Time from the first dose to progression or death from any cause.
Measure:Key Secondary Objective: To determine the duration overall response (OS).
Time Frame:44 months
Safety Issue:
Description:Time from the first dose to death of any cause.
