Title: A Phase I/II Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety of Eptifibatide as Treatment for Acute Pain Episodes in Sickle Cell Disease
Brief Summary: This study will evaluate the safety of eptifibatide in sickle cell patients and how well it works during the course of painful crises. The overall hypothesis that we seek to test is that increased platelet activation and the resultant inflammatory responses are important contributors to the problems of sickle cell disease. Sickle cell disease has been referred to both as a condition associated with increased risk of blood clots and increased inflammation. A painful crisis represents the most common cli nical problem in sickle cell disease, but the treatment of these crises remains inadequate.


Options:
A: Inclusion Criteria:

* Adult patients with SCD of any phenotype

Exclusion Criteria:

* Patient has a history of allergic reaction to either diamorphine/morphine or ibuprofen
* Patient has contraindications to diamorphine/morphine or ibuprofen, e.g. peptic ulcer disease, non-steroidal anti-inflammatory drug (NSAID)-induced asthma
* Patient in a drug dependency programme
* Patient is on renal dialysis
* Stroke within the last 6 weeks
* Platelet count less than 50 x 10\^9/l
* Patient is pregnant or breastfeeding
* Doctor unwilling to randomise the patient for other reasons
* Previous participation in the trial
* Patient receiving drug treatment with which opioids or NSAIDs are likely to interact significantly
* Stage 1 - 5 chronic kidney disease (ref Appendix 2), including urine protein: creatinine ratio of \>50 (Because the ibuprofen dose is substantial it is felt that precautions should be taken to exclude those who have any signs of chronic kidney disease. One of the signs of kidney disease is "persistent proteinuria". Therefore, the patient who intermittently has proteinuria(which could be due to other reasons) could still participate.)
