About this study

Official title: Feasibility of Methylene Blue-based Combination Therapy in the Radical Treatment of Adult Patients With Plasmodium Vivax Malaria in Ethiopia: a Randomised Controlled Pilot Trial

Feasibility of methylene blue-based combination therapy in the radical treatment of adult patients with Plasmodium vivax malaria in Ethiopia: a randomised controlled pilot trial

Study rationale:

Read more

Elimination has become the goal of malaria programmes in an increasing number of endemic countries and regions. Primaquine (PQ) is the only registered drug for radical cure of Plasmodium vivax malaria. Prolonged PQ-based combination therapy carries safety concerns and resistance to chloroquine (CQ) and PQ is emerging. Methylene blue (MB) has recently been shown to be safe and effective in the treatment of Plasmodium falciparum malaria in West Africa. As there is evidence for MB probably being effective against the hypnozoites of Plasmodium vivax, MB-based drug regimens could be an alternative to PQ-based combination therapy in Plasmodium vivax malaria.

Study objectives:

The main objective of this trial is to study the feasibility of MB-based combination therapy in patients with uncomplicated P. vivax malaria in an endemic area of Ethiopia.

Read the detailed description

The specific aims are (1) to test the feasibility and costs of methods and procedures for later use of MB-based combination therapy on a large scale, (2) to assess the safety of MB-based combination therapy, (3) to estimate the efficacy of MB-based combination therapy against malaria relapse, (4) to study the community acceptance of MB-based combination therapy, and (5) to strengthen the local capacity for malaria research and control in Jimma/Ethiopia.

Study design:

The study is designed as a pilot trial in adult patients with uncomplicated P. vivax malaria in Jimma, Ethiopia. Patients will be randomised to three treatment groups:

  1. Arthemeter/Lumefantrine (AL)
  2. AL-PQ, and
  3. AL-MB. Follow-up will be over a period of 6 months.

Study population:

Adult patients with uncomplicated P. vivax malaria (age ≥18 years) in Jimma/Ethiopia (G6PD deficient subjects are excluded) will become enrolled in the outpatient departments of the study centres. The sample size will be 33 per study arm, a total of 99 patients.

Study treatments:

  • AL standard treatments twice daily (total of 80 mg/dose A plus 480 mg/dose L) over first three study days
  • PQ 15 mg once daily for 14 days
  • MB 780 mg once daily for 14 days Treatments will be 100% directly observed.

Study outcomes:

Outcome parameters will be on feasibility and costs (e.g. recruitment rates, retention rates, costs per patient), on safety parameters (e.g. haemoglobin development during follow-up, incidence of adverse events), on efficacy parameters (e.g. incidence of P. vivax relapse during follow-up, malaria recurrence-free efficacy until day 180), and on community acceptance (e.g. perceptions on blue urine) during follow-up.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Artemeter-Lumefantrine and MB (combination therapy), Artemeter-Lumefantrine (combination therapy) and Artemeter-Lumefantrine and Primaquine (combination therapy) in people with Vivax Malaria, run by Heidelberg University.

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 6 inclusion and 8 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: withdrawn, as of the sponsor's last update on 25 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Study feasibility (time frame: 180 days). 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 25 Mar 2020.
