Trial outcomes

Primary outcomes

1

Recruitment and retention rates

Proportion of eligible patients who get recruited to the study; number of enrolled patients who complete 6-month study

Time frame
up to 28 weeks
2

Incidence of Treatment-Emergent Adverse Events as assessed by participant report

Collect all adverse events reported by patients and determine if related to study drug

Time frame
up to 28 weeks
3

Pain assessed by the Adult Sickle Cell Quality of Life Measurement System (ASCQ-Me) Pain Impact questionnaire

The Adult Sickle Cell Quality of Life Measurement System (ASCQ-Me) Pain Impact questionnaire is a patient-reported outcome measure of pain level in the past 7 days. The ASCQ-Me pain scale ranges from 0-100, with a standardized mean of 50 and a standard deviation of 10, where lower scores signify worse disease impact.

Time frame
up to 28 weeks

Secondary outcomes

1

Serum CTX-1

Measurement of C-terminal telopeptide of type I collagen (CTX) in serum as a biomarker for osteoclast activity (bone resorption)

Time frame
baseline, 3 months, 6 months
2

Serum P1NP

Measurement of Procollagen type I N-terminal propeptide (P1NP) in serum as a biomarker for osteoblast activity (bone formation)

Time frame
baseline, 3 months, 6 months
