Researchers are evaluating the safety and immune response of a chikungunya virus virus-like particle (CHIKV VLP) vaccine in children aged 1 to under 12 years. This phase 3, global, randomized, double-blind, placebo-controlled study aims to compare the vaccine with a placebo to understand its effects in this young population. The study focuses on measuring the vaccine's ability to produce antibodies and monitoring safety events over an extended follow-up period. Participants will receive either the CHIKV VLP vaccine, which contains virus-like particles adsorbed on aluminum hydroxide adjuvant, or a placebo consisting of formulation buffer. The vaccination occurs on Day 1, followed by monitoring for adverse events up to Day 29 and immune response assessment on Day 22. The study is planned to continue safety monitoring through Day 732 for those who complete the trial. During the study, children will undergo medical history reviews, physical examinations, and regular safety assessments including recording of any adverse events. Researchers will collect blood samples to measure antibody responses on Day 22 and monitor for any serious or medically significant events throughout the trial. Participants are expected to attend all scheduled visits and comply with study procedures over the course of the study period.

Researchers are evaluating quabodepistat-based treatment regimens for adults and adolescents aged 14 years and older with rifampicin-resistant or multidrug-resistant pulmonary tuberculosis (RR/MDR-TB). This Phase 3, randomized, open-label, multicenter trial aims to determine if quabodepistat combined with other tuberculosis drugs can shorten treatment to 4 months and offer similar or better effectiveness and safety compared to the current 6-month WHO-recommended treatments. The study includes two main groups based on fluoroquinolone sensitivity: fluoroquinolone-sensitive and fluoroquinolone-resistant RR/MDR-TB. Participants will be randomly assigned to receive either experimental or control treatments. For fluoroquinolone-sensitive RR/MDR-TB, the experimental regimen is BPaQM (bedaquiline, pretomanid, quabodepistat, moxifloxacin) for 4 months, compared to the control BPaLM (bedaquiline, pretomanid, linezolid, moxifloxacin) for 6 months. For fluoroquinolone-resistant RR/MDR-TB, the experimental treatment is BPaQ (bedaquiline, pretomanid, quabodepistat) for 6 months, versus the control BPaL (bedaquiline, pretomanid, linezolid) for 6 months. Drug dosing schedules vary by regimen, with bedaquiline dosing starting with daily doses followed by maintenance doses and all other drugs dosed once daily. Participants will be followed for 16 months after randomization, during which time researchers will assess treatment effectiveness by measuring the proportion of participants with unfavorable outcomes up to 12 months following randomization. Safety and tolerability will be monitored through recording adverse events from the first dose until two weeks after treatment ends. The study includes sputum sample collection, chest X-rays, laboratory tests, and monitoring for side effects. Independent committees oversee data monitoring and outcome adjudication to ensure participant safety and study integrity.
