About this study

Official title: Evaluation of the Safety and Efficacy of Dihydroartemisinin-piperaquine for Intermittent Preventive Treatment of Malaria in HIV-infected Pregnant Women

Trial to evaluate the safety and efficacy of DHA-PPQ for Intermittent Preventive Treatment (IPTp) in HIV-infected pregnant women receiving cotrimoxazole prophylaxis (CTXp) and antiretroviral (ARV) drugs and using long lasting insecticide treated nets will be conducted in Mozambique and Gabon where malaria and HIV infection are moderate to highly prevalent. In addition, the possibility for a PK interaction between DHA-PPQ and ARV drugs will be assessed in a sub-sample of participants. Women will receive ARV therapy according to national guidelines and their infants will be followed until one year of age to evaluate the impact of DHA-PPQ on MTCT-HIV.

Read the detailed description

Background

Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is recommended for malaria prevention in HIV-uninfected women but it is contraindicated in those HIV-infected on cotrimoxazole prophylaxis (CTXp) due to potential adverse effects. A recent trial showed that an effective antimalarial added to CTXp and long-lasting insecticide treated nets (LLITNs) in HIV-infected pregnant women improves malaria prevention and maternal health. However, the antimalarial used -mefloquine- was not well tolerated and it was associated with an increase in HIV viral load at delivery and a two-fold increased risk of MTCT-HIV. These findings highlight the need to find alternative drugs with better tolerability and safety profile to prevent malaria in this vulnerable group and to further study the pharmacological interactions between antimalarials and antiretrovirals (ARVs).

Dihydroartemisinin-piperaquine (DHA-PPQ), because of its long half-life and good tolerability has been shown to improve antimalarial protection in HIV-uninfected pregnant women, constituting the most promising candidate for IPTp in HIV-infected pregnant women. However, there is limited information on the pharmacokinetics of DHA-PPQ with concomitant use of ARV drugs and CTX, particularly in pregnant women.

Objectives

  1. To evaluate the safety, tolerability and efficacy of DHA-PPQ as IPTp for malaria prevention in HIV-infected pregnant women receiving daily CTXp and ARV drugs
  2. To assess the effect of DHA-PPQ as IPTp on mother to child transmission of HIV
  3. To study the effects of DHA-PPQ on the pharmacokinetics of clinically relevant doses of ARV drugs used for prevention of MTCT and treatment of HIV infection
  4. To evaluate the effectiveness of CTXp in clearing malaria parasites in HIV-infected pregnant women

Methods

The trial has been designed as a randomized double blind placebo-controlled superiority trial to evaluate the safety and efficacy of DHA-PPQ as IPTp in HIV-infected pregnant women taking daily CTXp and ARV drugs. The trial sites are located in Central and South Eastern sub-Saharan Africa (Gabon and Mozambique), where HIV prevalence among pregnant women ranges from 6 to 29%.

Based on previous estimations at the study sites and assuming a prevalence of peripheral parasitaemia at delivery of 7.5% with CTXp, it is estimated that 298 women per arm will be required to detect with 80% power a significant (p<0.05) decrease of 5% or more in the prevalence of peripheral parasitaemia in the CTXp+IPTp-DHA-PPQ group. In order to allow for 10% losses to follow up, it is calculated that 332 women/study arm will need to be recruited (total n=664). Furthermore, assuming a 5% MTCT-HIV in the control group, this sample size will have an 80% power to detect at the 5% level of significance, 2.2 times difference in the risk of MTCT-HIV.

The trial will have two study arms; HIV-infected pregnant women participating in the trial will be randomized to receive either:

  1. Monthly doses of IPTp-DHA-PPQ over three days plus daily ARVs and cotrimoxazole prophylaxis
  2. Monthly doses of IPTp-placebo over three days plus daily ARVs and cotrimoxazole prophylaxis

Women will receive ARV therapy according to national guidelines and their infants will be followed until one year of age to evaluate the impact of DHA-PPQ on MTCT-HIV.

Participants will be asked to visit the ANC monthly and to deliver at the study health facilities. Adherence to CTX prophylaxis and ARV therapy, as well as use of the LLITNs use will be assessed monthly at the scheduled antenatal care (ANC) clinic visits.

Pharmacokinetic (PK) sub-study The possibility for a PK interaction between DHA-PPQ and ARV drugs will be assessed in a sub-sample of participants (n=200).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dihydroartemisinin-piperaquine (DHA-PPQ) in people with Malaria and HIV/AIDS, run by Barcelona Institute for Global Health at 2 sites in 2 countries.

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 4 inclusion and 5 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: finished, as of the sponsor's last update on 1 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Gabon, Mozambique. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Maternal parasitaemia at delivery (time frame: Delivery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03671109, which also lists 4 linked publications.

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 1 Oct 2024.
