This is a randomized, placebo-controlled, double-blind trial to evaluate the efficacy, tolerability, and safety of ESO-101 in adult patients with active eosinophilic esophagitis (EoE). Patients will be screened at 2 visits (Visit 1 and Visit 2) during which their eligibility will be assessed based on endoscopy-independent criteria (Visit 1) and based on the histologic assessment of esophageal biopsy samples taken during the screening endoscopy (Visit 2). Eligible patients will be randomized 2:1 to once-daily treatment with ESO-101 or placebo and treated for 28 days starting on Day 0. Further clinic visits will be performed at Day 14 (Visit 4) and Day 28 (Visit 5, end of treatment) to assess the efficacy, tolerability, and safety. In addition, a safety follow-up call will be scheduled 2 weeks after the end of treatment (Day 42, Visit 6).

This is a single-centre, open-label, Phase Ib study designed to assess if intravenous injection of approximately 3200 P. falciparum (NF54 strain) sporozoites can be safely administered to achieve blood-stage parasitaemia with a kinetics/PCR profile that will allow for the future characterisation of antimalarial blood-stage activity of new chemical entities in a relatively small number of participants during early drug development.
Healthy, malaria-naïve adults, aged 18-55 years, will be enrolled in a maximum of 2 cohorts. Enrolment into the cohorts will proceed sequentially, with two target levels of parasitaemia, i.e., 5000 parasites/mL blood in Cohort 1 and 10000 parasites/mL blood in Cohort 2.
(Based on observed levels of parasitaemia in Cohort 1, the target threshold for treatment in Cohort 2 was maintained at 5,000 p/mL (vs 10,000 p/mL in the protocol)).
The 3-day antimalarial therapy regimen will be further administered and monitored until parasite clearance. Safety and tolerability will be monitored during the whole study duration.

This was a single centre, randomised, double-blind, placebo-controlled Phase Ib study, to evaluate the safety, tolerability and chemoprotective activity of P218 in a controlled P. falciparum sporozoite infection model.
Healthy men and women, aged 18 to 45 years were to be enrolled in 3 study cohorts and to be administered either P218 or placebo twice, 48 hours apart. Subjects in cohorts 2 and 3 were to be inoculated with P. falciparum sporozoites. Enrolment in cohorts was to proceed sequentially, to facilitate review of data by a Safety Review Team (SRT) before proceeding with a subsequent cohort.
In cohort 1, safety and tolerability of P218 was assessed. In cohorts 2 and 3, chemoprotective activity of P218 against malaria infection was assessed, as well as the Influence of time of initiation of the P218 treatment on the protective effect.
