Optimizing Hydroxyurea Therapy in Children With Sickle Cell Anemia In Malaria Endemic Areas: The NOHARM Maximum Tolerated Dose (MTD) Study
Uganda250 participantsStarted 2026-05-13
Plain-language summary
NOHARM MTD is an extension of a previous study for children with Sickle Cell Anemia (SCA) who were enrolled in the NOHARM study. All children enrolled in NOHARM received hydroxyurea treatment at a fixed daily dose of 20 mg/kg/day. This dose was selected as a likely safe dose, but does not escalate hydroxyurea to maximum tolerated dose "MTD" as is commonly done in the US. Without this information, we cannot know whether hydroxyurea treatment at the MTD would be feasible (since it requires closer monitoring to avoid hematological toxicities), safe (since adverse events may be greater with MTD, risk of malaria may be altered by MTD, and risk of infections as a result of neutropenia could also be greater with MTD) or beneficial (MTD is associated with higher hemoglobin and fetal hemoglobin concentration).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Adolescents with confirmed SCA who are currently enrolled in the NOHARM MTD Study of hydroxyurea at the Mulago Hospital Sickle Cell Clinic (MHSCC), will be eligible for the NOHARM MTD LT version 2.0 extension study after completing re-consent. An age-matched untreated (hydroxyurea-naïve) group of adolescents will also be enrolled as a Comparator Cohort. This will comprise 75 children from Kampala and surrounding districts, ages 11 - 18 years of age, with confirmed SCA.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
