Study of the Safety, Pharmacokinetics and Efficacy of Tinostamustine in Patients With Advanced Solid Tumors.
brief summary
Tinostamustine (EDO-S101) is a first-in-class alkylating deacetylase inhibitor designed to improve drug access to deoxyribonucleic acid (DNA) strands, induce DNA damage and counteract its repair in cancer cells. The main purpose of this study is to assess the safety, tolerability and efficacy of Tinostamustine in subjects with advanced solid tumours. Subjects will be given Tinostamustine via intravenous infusion on Days 1 and 15 of a 4-week cycle, the dose and infusion time will vary depending on the phase of the study.
detailed description
The study consists of 2 phases and 2 sub-studies:
This study is a multi-centre, open-label phase 1/2 study of single agent EDO-S101 in subjects with advanced solid tumours.
Phase 1 part of the study is designed to determine the safety, tolerability, maximum tolerated dose (MTD), recommended phase 2 dose (RP2D) and the Pharmacokinetic (PK) of EDO-S101 as a single agent in patients with solid tumours who have progressed after at least one (1) line of therapy and for whom no other standard therapy with proven clinical benefit is available.
Phase 2 part of the study is designed to evaluate the overall response rate (ORR) of the RP2D, plus the rate of patients with stable disease (SD) at 4 or 6 months, depending on the type of solid tumour. The RP2D was determined after phase 1 to be 80 mg/m2 of EDO-S101 administered over 1 hour on Day 1 and Day 15 of each 4-week treatment cycle.
In addition, two sub-studies are designed to better characterize the effect of EDO-S101: one at a dose of 60 mg/m2 administered over 60 minutes and the second at a dose of 80 mg/m2 administered over 80 minutes on cardiac repolarization (QTc) and other ECG parameters in the subjects with solid tumours.
Subjects were eligible for these studies if they had a histologically confirmed solid tumour, signed informed consent and met the inclusion/exclusion criteria. After providing informed consent, subjects were screened, and all procedures were performed as per protocol.
