Study of TG-1701, an Irreversible Bruton's Tyrosine Kinase Inhibitor, in Patients With B-Cell Malignancies

Phase 1
Terminated
Conditions
Non Hodgkin Lymphoma
Chronic Lymphocytic Leukemia
Interventions
Biological: Ublituximab
Registration Number
NCT03671590
Lead Sponsor
TG Therapeutics, Inc.
Brief Summary

This is a Phase 1 trial to evaluate the safety, pharmacokinetics and efficacy of TG-1701, a Bruton's Tyrosine Kinase (BTK) inhibitor in patients with relapsed or refractory B-cell malignancies.

Detailed Description

This Phase I clinical trial aims to evaluate the safety of the investigational drug TG-1701 both as a single-agent and in combination with other investigational drugs, specifically ublituximab and umbralisib. As per protocol v6.0, combination therapy (TG-1701 + Ublituximab + Umbralisib) will be discontinued and the participants from Arm 1 and 2 will be transitioned to the long-term extension period to receive TG-1701 monotherapy.
