Intravenous artesunate,
does it really help with Reduced in-hospital mortality in severe falciparum malaria?
research showsThe grade is B. AQUAMAT analyzed mortality in all 5,425 randomized participants: 230 of 2,712 (8.5%) versus 297 of 2,713 (10.9%), a 22.5% relative reduction (95% CI 8.1 to 36.9). SEAQUAMAT also found 107 of 730 deaths (14.7%) versus 164 of 731 (22.4%), an approximately 34.7% reduction (18.5 to 47.6). The mortality benefit is large and real, but both trials came from the same research network without confirmation by an independent team, giving B with 79 points.
ads claimDescriptions are evidence-aligned when limited to emergency treatment of severe malaria with better survival than quinine. Extending this to self-treatment of ordinary fever or prevention of mild malaria is outside this verdict.
Useful facts when choosing a product
- The graded claim is whether treatment reduces in-hospital mortality in people.
- AQUAMAT compared parenteral artesunate with parenteral quinine in hospitalized severe malaria.
- Artesunate requires use in a professional medical setting, including follow-up for possible delayed hemolysis.
What the research actually shows
AQUAMAT randomized 5,425 participants, 2,712 versus 2,713, and analyzed mortality in everyone. Death occurred in 230 of 2,712 (8.5%) versus 297 of 2,713 (10.9%), a 22.5% relative reduction (95% CI 8.1 to 36.9), without early stopping. SEAQUAMAT analyzed all 1,461 randomized participants and found 107 of 730 deaths (14.7%) versus 164 of 731 (22.4%), an approximately 34.7% reduction (18.5 to 47.6), stopping for efficacy at about two-thirds of the planned sample. The trials were large and concordant but shared the Mahidol-Oxford network and Wellcome Trust funding. The external 66-participant Sudan trial by Eltahir in 2010 found 1 of 33 versus 2 of 33 deaths and did not confirm the reduction, so independent-team confirmation remains absent.
Why this is classified as B (79)
The mortality reduction is large and credible, but both major trials shared a research network and funder and there is no external confirmatory trial, giving B with 79 points. The grade measures independent replication of evidence, not merely effect size.
Counterpoint. The evidence concerns treatment of severe malaria versus quinine and cannot be transferred directly to prevention or other stages of malaria.
Rejudgment record. Cross-check applied — Mortality fell substantially, but both major randomized trials shared the Mahidol-Oxford network and Wellcome Trust funding and no external independent trial confirmed the benefit
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced in-hospital mortality in severe malaria | B | Two large trials from the same research network found a substantial reduction. |
| Reduced mortality in African children with severe malaria | B | The mortality analysis of all 5,425 randomized children in AQUAMAT succeeded. |
| Reduced mortality in Asian adults and children with severe malaria | B | SEAQUAMAT found the same direction in 1,461 participants. |

Evidence Table
| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Study 1 | Open-label randomized multicenter quinine-controlled trial | 5,425 | Funded entirely by the Wellcome Trust; no pharmaceutical-industry funding | Primary endpoint: in-hospital mortality | 230/2,712 (8.5%) versus 297/2,713 (10.9%), relative reduction 22.5% (95% CI 8.1 to 36.9); not stopped early. | Pivotal large hard-endpoint randomized trial |
| Study 2 | Open-label randomized multicenter quinine-controlled trial | 1,461 | Charitable funding from the Wellcome Trust | In-hospital mortality | 107/730 (14.7%) versus 164/731 (22.4%), approximately 34.7% relative reduction (18.5 to 47.6); stopped for efficacy at about two-thirds of the planned sample. | Regional repetition within the same research network |
