Combining TL-895 with Ruxolitinib for treating Myelofibrosis

Official title: An Open-Label, Multicenter, Phase 1b/2 Study of the Safety and Efficacy of TL-895 Combined With Ruxolitinib in Janus-associated Kinase Inhibitor (JAKi) Treatment-Naïve Myelofibrosis (MF) Subjects and Subjects With MF Who Have a Suboptimal Response to Ruxolitinib

Run by Telios Pharma, Inc. · NCT05280509 · Data updated 2026-11-12

This study is testing if combining TL-895 with Ruxolitinib can help people with Myelofibrosis feel better, especially those who haven't responded well to Ruxolitinib alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults with Myelofibrosis who are either new to treatment or have not responded adequately to ruxolitinib.

Probably not a fit

Patients who have previously received any JAK inhibitor or have documented disease progression while on ruxolitinib may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of TL-895, a selective tyrosine kinase inhibitor, in patients with Myelofibrosis who are either treatment-naïve or have shown a suboptimal response to ruxolitinib. Participants must have a confirmed diagnosis of primary Myelofibrosis, post-PV Myelofibrosis, or post-ET Myelofibrosis, and meet specific risk criteria. The study aims to assess the safety and efficacy of this combination therapy in improving patient outcomes.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with Myelofibrosis who have limited responses to existing treatments.

How similar studies have gone: Other studies have explored similar combinations, but the specific use of TL-895 with ruxolitinib in this context is relatively novel.
