What this trial studies

Adult women with sickle cell disease who have regular menstrual cycles and frequent vaso-occlusive pain will complete a three-month baseline period without hormonal contraception. Participants will then receive a single injection of depot medroxyprogesterone acetate and be followed for three months to see changes in pain frequency, severity, and blood biomarkers. The protocol includes 6–7 in-person visits for urine pregnancy tests, blood draws, and surveys, plus weekly remote surveys and monthly home pregnancy tests. Study entry requires stable sickle cell medications and willingness to stop other hormonal contraception for the washout period and duration of the study.

Who should consider this trial

Good fit: Ideal candidates are women aged 18–50 with a confirmed sickle cell diagnosis who experience about one or more vaso-occlusive pain episodes per month, have regular 21–35 day menstrual cycles, are on stable sickle cell medications, and are willing to stop other hormonal contraception for the study.

Not a fit: People who are pregnant, breastfeeding, postmenopausal, do not have regular menstrual cycles, are unwilling to stop hormonal contraception, or are male are unlikely to be eligible or to receive benefit from this intervention.

Why it matters

Potential benefit: If successful, Depo-Provera could reduce the number or severity of vaso-occlusive pain episodes and improve quality of life while providing contraception.

How similar studies have performed: There is limited prior evidence on depot medroxyprogesterone in sickle cell disease; small reports exist but effects on pain and biomarkers are not well established.
