Study Details

Brief summary:

This study evaluates TL-895, a potent, orally-available and highly selective irreversible tyrosine kinase inhibitor for the treatment of Myelofibrosis. Participants must have MF (PMF, Post PV MF, or Post ET MF) who are JAKi treatment-naïve or those who have a suboptimal response to ruxolitinib.

Interventions and Outcome Measures

Arms

experimental: Phase 1b - Dose Level 1

150 mg of TL-895 will be administered orally, twice daily (BID) continuously starting on Day 1 in a 28-day cycle combined with the subject's pre-study stable dose of ruxolitinib.

experimental: Phase 1b - Dose Level 2

300 mg of TL-895 will be administered orally, twice daily (BID) continuously starting on Day 1 in a 28-day cycle combined with the subject's pre-study stable dose of ruxolitinib.

experimental: Phase 1b - Dose Level 3

450 mg of TL-895 will be administered orally, twice daily (BID) continuously starting on Day 1 in a 28-day cycle combined with the subject's pre-study stable dose of ruxolitinib.

experimental: Phase 2 - Cohort 1 JAKi treatment-naïve MF

The RP2D of TL-895 as determined in Phase 1b will be administered orally, twice daily (BID) continuously starting on Day 1 in a 28-day cycle.

The dose of ruxolitinib will be based on the subject's baseline platelet count.

experimental: Phase 2 - Cohort 2 suboptimal response to Ruxolitinib

The RP2D of TL-895 as determined in Phase 1b will be administered orally, twice daily (BID) continuously starting on Day 1 in a 28-day cycle.

The dose schedule will be the stable ruxolitinib dose schedule as the subject is currently taking prior to entry into the study.

Interventions

TL-895

TL-895 is an experimental tyrosine kinase inhibitor anticancer drug taken by mouth.

Ruxolitinib

Ruxolitinib is an FDA-approved janus kinase inhibitor anticancer drug taken by mouth.

Primary outcome measure

  • Phase 1b - Recommended Phase 2 dose of TL-895 in combination with ruxolitinib [ Time Frame: 28 days ]
  • Phase 2 - Spleen Volume Reduction (SVR) at Week 24 [ Time Frame: 24 Weeks ]
