Assessment of Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Various Formulations and Doses of PWT-143

Malignancies Clinical Trial

Official title: Assessment of Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Ascending Oral Doses of Various Formulations of PWT-143 in Healthy Subjects

Status Completed

Clinical Trial Summary

This single center first in human (FIH) study will comprise 2 parts; Part 1 will consist of 3 sequential dose groups (Groups A, B and C) and Part 2 will consist of 1 dose group (Group A). There will be an option to include 2 additional dose groups in Part 1 (Groups D and E) to assess alternative dose levels or formulations, if required.

In each study part, each subject will receive a single dose of investigational medicinal product PWT-143 in each of 2 study periods (total of 2 single doses).

Clinical Trial Description

This first-in-human study will comprise 2 parts. In each part, each subject will receive a single dose of investigational medicinal product (IMP) in each of 2 study periods (total of 2 single doses).

Part 1 (Single Ascending Dose) This is an open-label, single dose design. It is planned to enroll up to 3 sequential groups (Groups A, B and C), comprising 3, 6 and 6 subjects, respectively, with 2 optional additional groups (Groups D and E), each comprising 6 subjects, to assess alternative dose levels or formulations (described below), if required.

The starting dose, dose increments and dose range are based on available pre-clinical data. Current planned dose levels are: 10, 30, 60, 90 and 150 mg (dose levels 1, 2, 3, 4 and 5, respectively); however, doses above 10 mg will be selected based on a review of emerging data from this study.

It is planned to use Formulation 1 for dose administration in Part 1 (Group A), selected from 3 test formulations. However, based on the exposure seen in the emerging data, an alternative formulation may be selected for dose comparison or escalation.

Part 2 (Food Effect Assessment) This is an open-label, randomised, single dose, 2-way crossover design to assess a selected formulation of PWT-143 in the fed and fasted states. Subjects will be administered a single dose of investigational medicinal product in the fed and fasted states across 2 study periods according to the randomisation schedule. There will be a minimum washout period for PWT-143 of 7 days between dose administrations in Periods 1 and 2.

It is planned that 1 group comprising 8 subjects will participate in Part 2. Subjects will be considered evaluable if they have received both treatments (ie, fed and fasted) and have completed safety assessments and PK sampling up to 24 h post-dose. ;
