Antimalarial safety in early pregnancy (first trimester)
A Multicentre Open-label, Non-inferiority Adaptive Platform Randomised Controlled Trial to Evaluate the Efficacy, Safety, and Tolerability of Antimalarials for the Treatment of Uncomplicated Malaria in the First Trimester of Pregnancy: Master Protocol
This trial will test whether three antimalarial medicines—dihydroartemisinin‑piperaquine, pyronaridine‑artesunate, and artemether‑lumefantrine—are safe and work well for pregnant women with uncomplicated malaria in their first trimester.

What this trial studies
SAFIRE is a Phase 3, multi‑center interventional trial testing commonly used artemisinin‑based combination therapies in women with microscopy‑confirmed P. falciparum infection between about 2 and 13+6/7 weeks gestation. Eligible participants are enrolled at sites in Burkina Faso, Mali, and Kenya and are assigned to receive one of the antimalarial regimens under close clinical and obstetric monitoring. The trial collects safety data on maternal and fetal outcomes, treatment tolerability, and parasitological clearance, with follow‑up through delivery and newborn assessment. Results aim to provide more robust first‑trimester human data to inform treatment guidance in malaria‑endemic settings.
Who should consider this trial
Good fit: Pregnant people aged 16 or older with microscopy‑confirmed P. falciparum infection between roughly 2 and 13+6/7 weeks gestation, hemoglobin ≥7 g/dL, who live in the local catchment area and are willing to follow study procedures and deliver at the study facility are ideal candidates.
Not a fit: People with severe malaria, major concurrent illnesses, known HIV infection, a history of major pregnancy complications, known allergy to study drugs, or who cannot remain in the catchment area or deliver at the facility would be excluded and unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, the trial could expand safe, effective antimalarial options in the first trimester and reduce reliance on older, less effective drugs, improving outcomes for mothers and babies.
How similar studies have performed: Observational data and inadvertent first‑trimester exposures support the safety of artemether‑lumefantrine in pregnancy, but randomized and robust first‑trimester data for other ACTs remain limited.
