TG Therapeutics, Inc. Announces Oral Presentation of Follow-Up Data from the Triple Combination of Ublituximab, Umbralisib, and Pembrolizumab in Patients with Relapsed/Refractory CLL and Richter’s Transformation at 60th American Society of Hematology Annu
Dec 03, 2018
Below summarizes the oral presentation.
Phase I/II Study of Umbralisib (TGR-1202) in Combination with Ublituximab (TG-1101) and Pembrolizumab in Patients with Relapsed/Refractory CLL and Richter’s Transformation (Publication Number: 297)
This oral presentation includes data from patients with relapsed or refractory CLL or Richter’s Transformation treated with the triple combination of ublituximab, umbralisib, and pembrolizumab. Fifteen patients were evaluable for safety (10 CLL patients and 5 RT patients) and 14 were evaluable for efficacy (10 CLL and 4 RT), with one RT patient too early to evaluate. Data highlights include:
- The triple combination was well tolerated, with immune mediated toxicities not appearing above what would be expected with either umbralisib or pembrolizumab alone
- 90% (9 of 10) Overall Response Rate (ORR) in patients with relapsed/refractory CLL, including one Complete Response (CR)
- 80% (4 of 5) ORR in BTK refractory CLL patients, of which 3 of 4 BTK refractory CLL responders achieved their response to U2 alone prior to introduction of pembrolizumab
- 50% (2 of 4) ORR in RT, with both responses being a CR
- Responses have been durable, and a median progression-free survival has not yet been reached
- The first patient treated remains progression-free for 36+ months, having now been off therapy for more than 24 months
PRESENTATION DETAILS:
The above referenced presentation is now available on the Publications page, located within the Pipeline section, of the Company’s website at www.tgtherapeutics.com/publications.cfm.
