Summary

This trial will investigate if the antibiotic minocycline can stop/reverse cognitive decline in people with Sickle Cell Disease, a disorder which affects people of African ancestry and can lead to learning, memory, and attention problems due to brain inflammation.

Who is the study for?
This trial is for adults over 18 with Sickle Cell Disease (SCD), specifically HbSS and HbS-β0thalassemia genotypes, who are treated at the University of Cincinnati Medical Center's SCD clinic. It includes those on hydroxyurea treatment but excludes other SCD genotypes, history of stroke or neurological disorders, premature birth before 30 weeks, chronic blood transfusion therapy, tetracycline allergy, pregnant or breastfeeding women, and individuals with autoimmune conditions.
What is being tested?
The study tests minocycline's safety and effectiveness in reducing brain inflammation and cognitive decline in people with SCD. Participants will be randomly assigned to receive either minocycline at two different doses (200 mg or 300 mg daily) or a placebo for one year. Their cognitive function will be assessed using the NIH Toolbox Cognition Battery at the start and end of the study.
What are the potential side effects?
Potential side effects from minocycline may include dizziness, fatigue, gastrointestinal issues like nausea or diarrhea; skin reactions such as rash; discoloration of teeth/gums; liver toxicity; and possibly an increased risk of autoimmune problems due to its anti-inflammatory properties.
