Researchers are evaluating the effects of etavopivat in adolescents and adults with sickle cell disease. This study aims to confirm whether etavopivat reduces the number of painful vaso-occlusive crises caused by blood vessel blockages. It also examines if the medicine helps reduce organ damage, improve exercise tolerance, and decrease fatigue. The study is a phase 3, randomized, double-blind, placebo-controlled trial lasting about two years. Participants will be randomly assigned to receive either oral etavopivat or a placebo. The treatment is given by mouth, and neither the participants nor the researchers know which treatment is given during the study to ensure impartial results. The primary treatment period is 52 weeks, during which the number of vaso-occlusive crises with medical contact will be measured. Secondary assessments include changes in hemoglobin levels, fatigue scores, walking distance, and other blood markers related to sickle cell disease. During the trial, participants will undergo regular evaluations including blood tests, walking tests, and fatigue assessments from baseline to week 52. Researchers will monitor the safety and effectiveness of etavopivat throughout the study. The total participation time is about two years, with ongoing follow-ups to observe the treatment effects and any side effects. All procedures aim to provide detailed information on how etavopivat affects sickle cell disease symptoms and patient well-being.

Researchers are evaluating how well different anti-malarial drugs work and how safe they are for treating uncomplicated Plasmodium falciparum malaria in adults, adolescents, and children. This study focuses on the parasite-killing effects and potential cure rates of these drugs when given alone or combined with others. It also looks at how the drugs are processed by the body to help decide doses for future studies. Participants will receive one of several treatments, including varying doses of the oral drug INE963, combinations of oral KAE609 Cipargamin with INE963 or KLU156, or the standard of care drug Coartem. The study has multiple parts with patients allocated randomly to different treatment groups. Dosing levels and combinations are tested to compare how effectively they clear the malaria parasite. During the study, participants will have their parasite levels monitored up to 7 days and clinical response assessed by day 29. Blood samples will be taken by day 22 to study drug levels and how the body absorbs and clears the medicines. Safety is monitored through reports of side effects until day 43. The total participation lasts through these assessments to understand treatment impact and tolerability.
