Is this trial a fit for you?

Likely a 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.

Probably 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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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 gone: 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.

Inclusion Criteria:

1. Provision of signed and dated informed consent form
2. Female, aged 18-50 years old
3. Diagnosis of sickle cell disease (SS, SB0,SB+,SC)
4. Report of at least 1 vaso-occlusive pain episode per month on average in the previous 6 months

6. Willing to discontinue any hormonal contraception at the time of enrollment. Washout period of 1 month since last use of all hormonal contraception, and 4 months since most recent administration of depot medroxyprogesterone, is required prior to enrollment in the study.
7. Have regular menstrual cycles (when not on hormonal contraception) with a usual length of 21 to 35 days.
8. Stable dose of hydroxyurea and other sickle cell-related medications for the past 6 months
9. Access to a device with text-messaging capability
10. Must be able to read and understand English
11. Willing to comply with study procedures

Exclusion Criteria:

1. Chronic inflammatory conditions, such as lupus or inflammatory bowel disease
2. History of VTE or stroke
3. Current use of crizanlizumab, voxelotor, or chronic transfusion therapy, including simple transfusion and red cell exchange transfusion, history of hematopoietic stem cell transplantation
4. Current use of hormonal contraception or the copper intrauterine device
5. Current pregnancy or pregnancy within the last 6 months
6. Current lactation
7. Polycystic ovary syndrome or irregular periods
8. Blood pressure \>= 160 systolic or \>=100 diastolic at screening visit
