About this study

Official title: A Phase 2 Multicenter Study of TL-895 in Subjects With Relapsed/Refractory Myelofibrosis, Janus Kinase Inhibitor Intolerant Myelofibrosis, Janus Kinase Inhibitor Treatment Ineligible Myelofibrosis, or Indolent Systemic Mastocytosis

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.

Being tested
TL-895, Placebo
Medical subject headings
Primary Myelofibrosis, Mastocytosis, Systemic

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cohorts 1-3: Determine the RP2D of TL-895

    The RP2D for Cohorts 1, 2 and 3 will be reported

    Measured: 9 months

  2. Cohort 5: Determine the RP2D of TL-895

    The RP2D for Cohort 5 will be reported

    Measured: Week 24

Secondary outcomes (2)
  1. Cohorts 1-3: Spleen volume reduction (SVR) rate

    The proportion of subjects achieving ≥35% SVR at Week 24 by MRI or CT scan (central review).

    Measured: Week 24

  2. Cohort 5: Changes in patient reported symptoms

    Mean change in patient reported symptom assessment

    Measured: Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TL-895 in people with Myelofibrosis and Indolent Systemic Mastocytosis, run by Telios Pharma, Inc. at 52 sites in 13 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 10 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 52 sites in Italy, United States, Germany, Spain, Australia and 8 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact John Mei (650-542-0136, jmei@teliospharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cohorts 1-3: Determine the RP2D of TL-895 (time frame: 9 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2024.
