A Study of SHP655 (rADAMTS13) in Sickle Cell Disease (RAISE)
A Phase 1 Randomized, Double-blind, Placebo-controlled, Multicenter, Ascending Dose, Safety and PK/PD Study of SHP655 (rADAMTS13) in Sickle Cell Disease at Baseline Health
SHP655 is a medicine used to treat sickle cell disease (SCD). The main aim of the study is to measure the safety and tolerability of SHP655 in SCD participants.
Study participants will receive SHP655 or placebo on Day 1. Their SCD will be treated by their doctor according to their doctor's usual clinical practice.
During the study, participants will be asked to follow-up on 13 days following SHP655 or placebo administration for safety assessment. Maximum duration of participation is expected to be about 2 months

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: From date of signing informed consent up to study completion (up to Day 31)
|
An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this investigational product or medicinal product.
An AE can therefore be any unfavorable and unintended sign (including a clinically significant laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not causality is suspected (ICH Guidance E2A 1995).
A serious adverse event (SAE) is any untoward clinical manifestation of signs, symptoms or outcomes (whether considered related to investigational product or not and at any dose) which results in death, is life-threatening, requires inpatient hospitalization, prolongation of hospitalization, is an important medical event.
Number of participants with AEs and SAEs will be assessed.
|
From date of signing informed consent up to study completion (up to Day 31)
|
Number of Participants With Binding and Inhibitory Antibodies to SHP655
Time Frame: From start of study treatment up to study completion (up to Day 31)
|
The number of participants will be summarized by dose for binding and inhibitory antibodies to SHP655 and will be reported as AEs.
The study completion date is defined as the date on which the last participant in the study completes the final assessments.
|
From start of study treatment up to study completion (up to Day 31)
