Clinical Trial Summary

The purpose of this study is to determine the safety and clinical effects of SCD-101 when given to adults with sickle cell disease.


Description:

This is single site, dose- escalation study of SCD-101 in participants with homozygous sickle cell disease (S/S) or S/beta 0 Thalassemia. All participants will be monitored for safety, tolerability, and dose-limiting toxicities. The study is divided into two parts. Part A is an open-label, non-randomized, non-placebo-controlled dose escalation study with a 28-day treatment phase and 14-day follow-up phase with five cohorts . Part B is a randomized, placebo-controlled, confirmatory 2x2 crossover cohort with a 28 day washout between periods, and a 28-day follow-up phase.

AST and/or ALT >3x upper limit of normal and/or creatinine >2x upper limit of normal or any other significant renal or hepatic impairment 5. Estimated creatinine clearance (CrCl) < 60 mL/min (Cockcroft- Gault formula) at screening. 6. QTc interval of >470 msec at trial entry and participant with congenital long QT syndrome. 7. No other significant sickle cell or non-sickle cell illness that would confound the results of the trial 8. Any condition that, in the view of the investigator, places the participant at risk because of participation in the trial, or may influence the result of the trial or the participant's ability to participate in the trial 9. Participant pregnant or nursing an infant or planning pregnancy during the course of the trial 10. History of allergic reactions attributed to sorghum or compounds of similar chemical or biologic composition (such as Nicosan, Niprisan, Jobelyn or Xickle). 11.
