Clinical Trial Summary

The purpose of this study is to determine whether ticagrelor is effective in reducing the number of days of pain, intensity of pain, and reducing the use of analgesics due to sickle cell disease


Clinical Trial Description

This is a randomised, double-blind, double-dummy, parallel-group, placebo-controlled, study evaluating 2 doses of ticagrelor in 90 patients aged 18 to 30 years, with sickle cell disease (SCD). Patients will be randomised to double-blind double-dummy treatment period in a 1:1:1 ratio (30 to each treatment group) to receive ticagrelor 10 mg twice daily (bid), or ticagrelor 45 mg bid, or placebo bid to determine the frequency of days with pain using an electronic diary (eDiary) every day. Approximately 180 patients will be enrolled. Patient will be followed for safety assessment during and after 2 weeks of treatment completion.

During the 16 week treatment period, patients will complete a daily eDiary concerning daily pain intensity, pain location, use of analgesics and absence from school or work. At the end of the study patients will be asked to rate the change in their sickle cell pain compared to the start of treatment. Platelet aggregation will be measured and reported as P2Y12 reaction units (PRU) pre-dose and 2 hours post-dose at week 4 and week 5 after treatment start. Pharmacokinetic (PK) parameters will be measured at 2 hours post-dose at week 4, and pre-dose and at 2 hours post-dose at week 5. Biomarkers will be assessed pre-dose at week 4, week 5 and week 8. During the study, patients will be evaluated for adverse events (AEs) including bleeding and vaso-occlusive crisis (VOC). ;
