Study Details

Study Description

Brief Summary

Phase 1, single -center study in 2 parts. The study designs for each part are well established for first-in-human studies and are appropriate to assess safety, tolerability and preliminary pharmacokinetics& pharmacodynamics.

Condition or Disease	Intervention/Treatment	Phase
Malaria	Drug: 20 mg/120 mg artemether-lumefantrine (AL) + 20 mg ruxolitinib phosphate (Rux); Other: 20 mg/120 mg artemether-lumefantrine (AL) + Placebo	Phase 1

Detailed Description

This is a randomised, single-blinded, placebo-controlled, single centre, phase 1 trial.

Eight healthy males or females, aged between 18-55 years old, who meet all of the inclusion criteria and none of the exclusion criteria, will be enrolled.

Abstinent female participants must agree to start a double method if they start a sexual relationship with a male during the trial. Female participants must not be planning in vitro fertilisation within the required contraception period.

Women of non-childbearing potential who will not require contraception during the trial are defined as: surgically sterile (tubal ligation is not considered surgically sterile), post-menopausal (spontaneous amenorrhoea for ≥12 months, or spontaneous amenorrhoea for 6-12 months and follicle-stimulating hormone (FSH) ≥40 IU/mL; either should be together with the absence of oral contraceptive use for >12 months).

Limitations/Caveats

A PK drug-drug interaction between artemether and Rux cannot be excluded, and more data is needed to properly characterize such a potential interaction. Investigation of possible PK drug-drug interactions were not within the scope of this study, due to small participant numbers, differing PK blood sampling schemes on Days 1 and 3, variability of artemether and lumefantrine PK parameters in the AL+Rux treatment group, and absence of a Rux-only treatment group.
