Účinnost, bezpečnost a snášenlivost KLU156 u dospělých a dětí s tělesnou hmotností ≥ 5 kg s nekomplikovanou malárií P. Falciparum (KALUMA)

30. října 2026 aktualizováno: Novartis Pharmaceuticals

Randomizovaná, otevřená, multicentrická studie k porovnání účinnosti, bezpečnosti a snášenlivosti KLU156 s Coartem® při léčbě nekomplikované malárie Plasmodium Falciparum u dospělých a dětí ≥ 5 kg tělesné hmotnosti s následnou fází prodloužení s opakovanou léčbou KLU156

This study aimed to confirm the efficacy, safety and tolerability of KLU156, a fixed dose combination of ganaplacide (KAF156) and a solid dispersion formulation of lumefantrine (lumefantrine-SDF), when administered once daily for three days in adults and children ≥ 10 kg of body weight suffering from uncomplicated P. falciparum malaria (with or without other Plasmodium spp. co-infection).

In the extension phase, the safety, tolerability and efficacy of repeated treatment with KLU156 was assessed for a maximum of approximately 18 months in patients who did not experience early treatment failure (ETF), who did not experience any study treatment-related SAE (Serious Adverse Event) previously and who gave informed consent to participate in the Extension phase.

Detailní popis

The purpose of this study was to confirm the efficacy, safety and tolerability of KLU156 in patients with uncomplicated P. falciparum malaria (with or without other Plasmodium spp. co-infection) by demonstrating that KLU156 is non-inferior to Coartem.

  • The total study duration was up to approximately 20 months.
  • The treatment duration was 3 days for each malaria episode.
  • The visit frequency was Days 1-3 (hospitalized) and 5 follow-up visits (Days 4, 8, 22, 29 and 43) in the Core phase and Days 1-3 (hospitalized) and 3 follow-up visits (Days 4, 8 and 29) in the Extension phase.

This study had two different primary outcomes depending on the submission (US New Drug Application (NDA) or non-US submissions).

Protocol amendment 01 increased the minimum body weight requirement for study participation from ≥ 5 kg to ≥ 10 kg and revised the statistical analysis plan to exclude patients < 10 kg from the main analyses.
