About this study

Official title: A First-in-Human, Single-Centre, Single Ascending Dose Study to Assess the Safety, Tolerability and Pharmacokinetics of Intramuscular Injection(s) of Long-Acting Injectable Formulations of MMV055 Alone (Part A) and in Combination With MMV371 (Part B) in Healthy Participants

This is a single-centre, participant- and investigator-blind, randomised, placebo controlled, single ascending dose study to assess the safety, tolerability and PK of a single dose of IM depot injection(s) of LAI formulations of MMV055 administered alone (Part A) and in combination with MMV371 (Part B) in healthy participants.

It is planned to enroll up to 6 sequential cohorts of 8 healthy male participants and healthy female participants of non-childbearing potential in Part A. In Part B, up to 3 sequential cohorts of 8 healthy male participants and healthy non-pregnant, non-lactating female participants will be enrolled. In each cohort, participants will be randomised in a ratio of 6 active investigational medicinal product (IMP) to 2 placebo.

Part A of the study will include two components, Parts A1 and A2. Part A1 includes two initial cohorts, with planned doses of 40 and 100mg, respectively. It is intended to document the human elimination T1/2 of MMV055, which will then be used to shorten the proposed End of Study (EOS) of 48 weeks, if possible.

All cohorts will follow a sentinel dosing design. On Day 1, two sentinel participants (sentinel group) will be randomly assigned to receive a single IM dose of either active IMP or placebo (1 participant each) to assess safety and tolerability (including ISRs).

The sentinel group will be dosed concomitantly at least 7 days prior to the rest of the cohort (main group). The main group will comprise 6 participants randomly assigned to receive a single IM dose of either active IMP or placebo in a 5:1 ratio to assess safety and tolerability (including ISRs).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MMV055 Dose 1, MMV055 Dose 2 and MMV055 Dose 3 in people with Malaria, Falciparum, run by Medicines for Malaria Venture at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 37 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 15 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Medical Director, MD, PhD (+41 22 555 03 00, info@mmv.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety - Incidence of AEs (time frame: From enrollment to the last follow up visit at week 56). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2026.
