Trial Outcomes & Findings for Enhancing Preventive Therapy of Malaria In Children With Sickle Cell Anemia in East Africa (EPiTOMISE) (NCT NCT03178643)

NCT ID: NCT03178643

Last Updated: 2024-04-23

Results Overview

The primary endpoint is the cumulative incidence of clinical malaria expressed as episodes per person-year at risk. Time at risk will begin when study participants are randomized and receive study drug (i.e. begin chemoprevention) and end when participants reach the end of the observation period.

Participant Flow

Potential participants will be screened for inclusion in the existing pediatric. Currently, SCA patients are cared for in two parallel clinics: 1) the pediatric medical officer staffs a weekly SCA clinic, and 2) the AMPATH HematoOncology outreach team staffs a monthly 2-day SCA clinic at HBCH. Potential participants will be screened for eligibility. If they meet all inclusion criteria and do not meet any exclusion criteria, they will be offered enrollment following informed consent.
