Not a traditional drug phase: testing Hydroxyurea (HU) for Sickle Cell Disease
The wide interindividual variability in clinical response to hydroxyurea therapy in the management of sickle cell disease has limited its use. These variabilities have been linked to differences in pharmacodynamics, pharmacokinetics, and pharmacogenetics.
This is an observational study. You are not assigned a new experimental drug. Researchers measure what already happens in your care or in daily life.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
This listing is observational (StudyType). The registry does not assign a new experimental drug as the study intervention.
They plan to enroll about 100 people at Ile-Ife. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
Official title (unrewritten)
Pharmacogenetics and Model-Informed Optimisation of Hydroxyurea Therapy in Sickle Cell Disease Patients of Nigerian Descent
Interventions: Hydroxyurea (HU)
Primary outcome (registry wording): Increase in foetal haemoglobin
Who it is for (from inclusion criteria)
Ages 18 Years to any
Patients with confirmed diagnosis of sickle cell disease (SCD) (e.g., HbSS, HbSC) and of Nigerian descent
Patients currently on hydroxyurea therapy or hydroxyurea-who have not tried this kind of treatment before patients who are willing to commence hydroxyurea therapy
Patients whose genotypic profile for the major metabolising enzymes has been previously done e.g. CYP2D6
Patients who consent to be part of the study
Who the registry excludes
Patients with severe comorbidities that may significantly alter pharmacokinetics (e.g., advanced renal or hepatic failure)
Patients in acute crisis at the time of sampling
Patients with documented poor adherence to other medications previously on
This study is not a treatment protocol and no experimental treatments are involved. Study participants may be seen as needed for clinical, translational and basic research studies, or as medically indicated.
This study will collect representative blood samples from healthy children and adults and from children and adults who have unique red blood cell features that are related to sickle cell disease. Sickle cell disease is a blood disease that limits the ability of red blood cells to carry oxygen throughout the body.
Background: Some people with the same disorder on a genetic level have more complications than others. Researchers want to look for a link between the PKLR gene and sickle cell disease (SCD) symptoms.
