Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Phase 1b - Recommended Phase 2 dose of TL-895 in combination with ruxolitinib	Dose-limiting toxicities (DLTs) will be used to establish the maximum-tolerated dose (MTD) of TL-895 in combination with ruxolitinib. The safety review committee (SRC) will determine the RP2D based on safety and efficacy data of the combination of TL-895 and ruxolitinib.	28 days
Primary	Phase 2 - Spleen Volume Reduction (SVR) at Week 24	The proportion of subjects achieving SVR of =35% at Week 24 by magnetic resonance imaging (MRI) or computed tomography (CT) scan.	24 Weeks
Secondary	Phase 1b - Spleen Volume Reduction (SVR) at Week 24	The proportion of subjects achieving =35% SVR at Week 24 by MRI or CT scan.	24 Weeks
Secondary	Phase 1b - TSS reduction at Week 24	The proportion of subjects achieving =50% reduction in TSS at Week 24 by Myelofibrosis Symptom Assessment Form (MFSAF) v4.0.	24 Weeks
Secondary	Phase 2 - TSS reduction at Week 24	The proportion of subjects achieving =50% reduction in TSS at Week 24 by MFSAF v4.0.	24 Weeks
Secondary	DOR Spleen	Time from initial SVR of = 35% by MRI/CT until the first occurrence of disease progression or death	48 Months
Secondary	Progression Free Survival	Time from first dose to progression or death from any cause.	48 Month
Secondary	Overall Survival	Time from first dose to death from any cause	48 Months
