Official title

A Phase 1-2, Open-Label Study of the Safety, Pharmacokinetics, Pharmacodynamics, and Preliminary Activity of Tolinapant in Combination With Oral Decitabine/Cedazuridine and Oral Decitabine/Cedazuridine Alone in Subjects With Relapsed/Refractory Peripheral T-cell Lymphoma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The primary purpose of the study is to assess safety, and to identify the recommended phase 2 dose (RP2D) of tolinapant in combination with oral decitabine/cedazuridine in Phase 1 and to assess preliminary efficacy as determined by overall response rate (ORR) in Phase 2. As no safe and tolerable dosing for the combination of tolinapant and decitabine/cedazuridine was identified based on protocol defined criteria, Sponsor decided to halt recruitment and to not conduct Phase 2 of the study.
