Superiority of ArTiMist Versus Quinine in Children With Severe Malaria

Proto Pharma Ltd151 enrolled

Overview

The purpose of this study is to demonstrate that ArTiMist (sublingual artemether spray) is better than intravenous quinine in reducing parasite counts by \>= 90% within 24 hours after the start of treatment in children with severe malaria, or uncomplicated malaria with gastrointestinal complications

Malaria causes significant morbidity and mortality in children in developing countries, despite the availability of highly effective antimalarial therapy. One of the key contributing factors is the delay in the initiation of treatment. ArTiMist is a sublingual formulation of the established antimalarial treatment, artemether. In previous studies good bioavailability has been demonstrated. In an exploratory study (ART003) ArTiMist demonstrated a non statistically significant improvement of 26% (when compared to intravenous quinine) in the numbers of patients experiencing a parasite reduction of \>= 90% within 24 hours of the initiation of treatment. This Phase 3 study is being conducted to establish whether treatment with ArTiMist in children with severe falciparum malaria or uncomplicated falciparum malaria with gastrointestinal complications is at least 20% superior in providing parasitological success (defined as \>= 90% reduction in parasite count at 24 hours after start of treatment) when compared to intravenous quinine.

Outcomes

Primary Outcomes

Parasitological Success (MITT)

Parasitological success defined as a reduction in parasite count of ≥ 90% of baseline at 24 hours after the first dose

Time frame: 24 hours after start of treatment

Parasitological Success (PP)

Parasitological success defined as a reduction in parasite count of ≥ 90% of baseline at 24 hours after the first dose

Time frame: 24 hours after start of treatment

Secondary Outcomes

Parasite Clearance Time (PCT) [MITT Population]

Parasite clearance time (PCT). Time in hours from the initiation of therapy until the first of two successive parasite negative smears (zero parasite counts) are obtained
