Summary

This trial is testing a new treatment for sickle cell disease, which is a blood disorder. The treatment is a combination of three drugs, and it is being compared to a standard treatment of just one drug.

Who is the study for?
Adults over 18 with confirmed sickle cell disease, symptomatic despite hydroxyurea treatment or refusing it. They must be stable (no recent acute SCD complications), weigh at least 40kg, and comply with care. Excluded are those unable to consent, pregnant/breastfeeding women, individuals with certain organ dysfunctions or severe concurrent diseases, drug/alcohol abusers within a year, and anyone on other experimental drugs recently.
What is being tested?
The trial is testing the effectiveness of nicotinamide alone and in combination with oral THU-decitabine in treating high-risk sickle cell disease. It's a randomized control study involving 20 subjects who will receive either one of the treatments or both together.
What are the potential side effects?
Potential side effects for this trial have not been explicitly listed but may include typical reactions to medications such as gastrointestinal issues, possible liver enzyme elevations due to nicotinamide or decitabine, fatigue, blood count changes and increased risk of infection.
