A Phase 1 Study Investigating the Safety, Tolerability and Pharmacokinetics of KNX100 in Healthy Volunteers
- Registration Number
- NCT04901078
- Lead Sponsor
- Kinoxis Therapeutics Pty Ltd
- Brief Summary
The primary objectives of this study are to evaluate the safety and tolerability of KNX100 administered orally as a single and multiple ascending doses in healthy volunteers.
- Detailed Description
This is an adaptive, Phase 1, first-in-human (FIH), single treatment, double blind, placebo controlled, randomized, single and multiple ascending dose study of KNX100 administered to healthy volunteers. Approximately 64 male and female healthy subjects will be enrolled into this study. Healthy subjects who meet all the eligibility criteria will be randomly assigned to Cohorts 1-5 for the Single Ascending Dose and Cohorts 1-3 for the Multiple Ascending Dose. Each cohort will evaluate 8 subjects; 6 subjects will receive KNX100 (study drug) and 2 subjects will receive placebo.
Each cohort will be enrolled sequentially, and dose escalation decisions will be made according to protocol by the Cohort Review Committee (CRC) consisting of the investigators and medical monitor. Subjects and clinical staff will be blinded to therapy assignment. KNX100 will be provided in capsule form as 5, 25 and 100 mg capsules for oral administration and the dose range will be 5 to 50mg.

- Subjects who donated blood or who had a comparable blood loss (approximately 500 mL) during the last 30 days prior to start of this study and while on study.
- Clinically significant findings on the screening, Day -1, or predose Day 1 electrocardiogram (ECG) or physical examination, including QTcF duration >450 ms for males and >470 ms for females on ECG.
- Thyroid function tests outside the normal reference ranges and deemed clinically significant by the study PI (and upon repeat).
- Safety laboratory tests that are outside the normal reference ranges and deemed clinically significant by the study PI (and upon repeat).
- Any history of meningitis, septicemia, or pneumonia.
