MULTIple Doses of IPTi Proposal: a Lifesaving High Yield Intervention (MULTIPLY)

January 23, 2026 updated by: Barcelona Institute for Global Health

As efforts to control malaria are stalling, and the disease is particularly severe in children under the age of two, it is imperative for countries in sub-Saharan Africa, with areas of moderate-to-high transmissions, to implement Perennial Malaria Chemoprevention (PMC) delivered through the Expanded Program on Immunization (EPI), which is the only feasible, sustainable and cost-effective strategy to reach this high-risk group. PMC is a full therapeutic course of antimalarial medicine (with sulfadoxine-pyrimethamine, SP) delivered to infants in the context of routine immunisation services during the first two year of life.

PMC has been shown to be safe, efficacious in reducing clinical malaria, anaemia and hospital admissions, and to be highly cost-effective; for all these reasons, the World Health Organization (WHO) recommended in 2010 Intermittent Preventive Treatment for Infants (IPTi) for malaria prevention. Only one African country - Sierra Leone -put IPTi into policy and practice. Concerned with this slow adoption, WHO in 2019 recommended adaptations be urgently tested through pilots assessing impact, operational feasibility and cost effectiveness. In 2022, WHO expanded that recommendation to cover children through the age of two because of studies documenting the value in children aged 12 to 24 months. The name for this preventive treatment has consequently changed to Perennial Malaria Chemoprevention (PMC) as the updated recommendation is no longer just for infants.

MULTIPLY is the pilot implementation of PMC in selected districts in Mozambique, Sierra Leone and Togo to maximise the delivery and uptake of PMC, to achieve the full potential of this intervention. Working with the ministries of health in Mozambique, Sierra Leone and Togo, MULTIPLY will give up to 6 doses of PMC in the first two years of life. PMC will be given at health facilities and EPI mobile outreach clinics using a paediatric dispersible formulation of SP, alongside routine vaccinations and vitamin A supplementation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will be conducted in 3 sub-Saharan African countries; Sierra Leone, Mozambique and Togo.

Sample size; Assuming an average population of a district/project area of 150,000 inhabitants and a percentage of U2 children of 5%, the project intervention will target approximately 45,000 U2 children in total (i.e. 7,500 children per country and per year for 2 years).

Study population; Children U2 who are eligible for IPTi in the selected MULTIPLY district of each country.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 months to 1 year (Child)

Accepts Healthy Volunteers

Yes

Study Population

All infants attending their 2nd EPI contact who are eligible to receive the corresponding immunisations.

Description

Inclusion Criteria:

All infants attending their 2nd EPI contact who are eligible to receive the corresponding immunisations.

Exclusion Criteria:

Infants/children; with acute malaria; known to have sulfa allergies; who have taken SP in the past 4 weeks; who are HIV-exposed or HIV-infected

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
