Study of TL-895 in Subjects With Myelofibrosis or Indolent Systemic Mastocytosis

Study Purpose

This study evaluates TL-895, a potent, orally-available and highly selective irreversible tyrosine kinase inhibitor for the treatment of Myelofibrosis (Cohorts 1-3) or Indolent Systemic Mastocytosis (Cohort 5). Participants must be diagnosed with Myelofibrosis and be relapsed/refractory (e.g., having failed prior therapy), intolerant, or ineligible to receive JAKi treatment, or be diagnosed with Indolent Systemic Mastocytosis.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.
