Plain English Summary

Background and study aims
The study is being done to find out if the existing 3-month depot medroxyprogesterone acetate (DMPA) contraceptive injection is as effective and safe when injected every 6 months under the skin instead of into the muscle. The product being tested is called ‘6-month DMPA SC’. A previous study of 21 women showed that injecting DMPA under the skin stopped 21 women from ovulating (i.e., producing eggs) for at least 6 months when it was given under the skin. This study will test if it prevents actual pregnancy and is safe among a larger number of women.

Who can participate?
Healthy, sexually active women aged 18 to 35 years who are willing to use 6-month DMPA SC as their only means of contraception for 12 months (i.e., receive two injections 6 months apart).

What does the study involve?
Participants in the study will receive two shots of 6-month DMPA SC (at enrollment and 6 months after the first injection) under the skin of either their abdomen or thigh. Participants will be asked to return for follow up visits at Months 3, 6 and 9, and a final visit at Month 12, and complete monthly pregnancy tests either at home or at the clinic during the study. Additional tests after the Month 12 visit to provide information on return to ovulation may be scheduled if a participant consents to participate.

What are the possible benefits and risks of participating?
There is no direct benefit from taking part in this study, however, participants may help to develop a new, longer-acting contraceptive method.
Pregnancy: Risk of pregnancy is low but unknown. Participants will be tested for pregnancy before and during the study to make sure they are not pregnant. Any positive tests will be confirmed by a blood test and/or ultrasound. The researchers will refer participants for medical care at NHS in the unlikely scenario that they become pregnant. Many studies have found that babies who are exposed to DMPA while in the womb do not have a higher risk of birth defects or health problems.
Future fertility: Participants' typical ability to get pregnant will return when the last injection wears off. It may take as long as a year after getting the last shot of 6-month DMPA SC for this to happen.
Skin reactions: There is a chance that participants will have skin reactions where they receive the shots. No skin reactions were reported to be severe or serious during previous studies.
Irregular bleeding: Most women have irregular bleeding, spotting or no bleeding at all while using DMPA. Regular bleeding is expected to return when most of MPA is cleared from the body.
Weight gain: Some women gain weight while using DMPA (about 3-5 pounds in a year).
Sexually transmitted infections: According to WHO, it is safe for women who are at high risk of sexually transmitted infections (STIs) including human immunodeficiency virus (HIV), to use DMPA. DMPA does not protect against STIs, including HIV.
Bone mineral density: Use of DMPA for more than 2 years may weaken bones (the condition known as osteopenia which may increase the risk of broken bones). It is not expected that getting two injections of 6-month DMPA SC in this study will have any effect on bones due to the short duration of the study (12 months).
Cancer: Some studies found a slightly increased risk of breast cancer among women using 3-month DMPA for 12 months or longer. It is unlikely that getting two injections of 6-month DMPA SC in this study will lead to breast cancer.
Allergic reaction: Severe allergic reaction to DMPA, also known as anaphylactic reaction, is rare. Such reactions usually happen right after the injection. The researchers will ask participants to remain in the clinic for observation for at least 30 minutes after each injection where we have drugs to treat severe allergic reactions and easy access to emergency care in the unlikely event of such a reaction.
Additional potential side effects: acne, headache, tiredness, decreased sexual desire, breast pain, depression.
Blood draw: It is possible that participants may feel some pressure or discomfort while their blood is being drawn and they may have a small bruise where the blood was drawn. There is also a small risk of infection with a blood draw.
Ultrasound: A transvaginal ultrasound may be done to confirm a positive urine pregnancy test. This procedure is usually not painful but may cause discomfort, anxiety or embarrassment.
Gynaecological examination: This examination usually does not hurt but may cause slight discomfort, anxiety or embarrassment.
Non-medical: Potential non-medical risks in this study include a breach of confidentiality, potentially missing work to come to study visits, and answering questions about sensitive subjects like sexual history and keeping a bleeding diary. The researchers will do their best to prevent anyone outside the study from knowing about participants in this study. All attempts will be made to accommodate the participants' availability when scheduling clinic visits.
If participants have a side effect after an injection, the drug cannot be removed immediately to stop the reaction. Most of the side effects do not pose a serious risk to health and go away with time without clinical care. Participants will be provided with study team contact details and emergency contacts for the study in case they experience any of the above risks. The site team will make every attempt to resolve the issue by providing appropriate medical care and ensuring the safety of their patients.

Scientific titleA Phase III, open-label, multicenter study to evaluate contraceptive efficacy and safety of depot medroxyprogesterone acetate (150 mg/ml) injected subcutaneously every 6 months
Study acronymDMPA-XT
Study hypothesisThe main objective is to evaluate the contraceptive efficacy of 6-month depot medroxyprogesterone acetate (DMPA) subcutaneously (SC) injected every 6 months for 12 months in the abdomen or thigh. The primary study endpoint is the occurrence of pregnancy, as defined by a positive urine pregnancy test and confirmed by a valid method (i.e., ultrasound and/or serum human chorionic gonadotropin (hCG)). The primary efficacy endpoint will be assessed by reporting the Pearl Index (pregnancies per 100 women-years of treatment) and an associated 95% confidence interval for the Pearl Index.
Ethics approval(s)Approved 20/05/2022, South Central - Oxford B Research Ethics Committee (Ground Floor, Temple Quay House, 2 The Square, Bristol, BS1 6PN, UK; +44 (0)207 104 8360; oxfordb.rec@hra.nhs.uk), ref: 22/SC/0104
ConditionContraception for up to 6 months
InterventionCurrent intervention as of 22/12/2023:
Subjects will be randomly assigned using a 1:1 allocation ratio to receive both of their subcutaneous injections of 6-month DMPA SC in either the abdomen or upper thigh. 6-month DMPA SC will be administered by a trained staff member as a single subcutaneous injection in either the abdomen or thigh at a dose of 150 mg in 1 ml using a 26-gauge 3/8-inch needle.

All subjects will receive two injections of 6-month DMPA SC: the first injection during the enrollment visit which will be scheduled during the first five days of the menstrual cycle, or at the time of switching from the previous form of highly effective contraception (e.g., contraceptive patch, ring, implant, pills, copper or hormonal IUD), and the second injection during the scheduled follow-up visit at month 6 (reinjection). There will be a plus 7-day grace period for reinjection at month 6 but women may receive re-injection up to 28 days late. Subjects who are more than 28 days late for reinjection will be discontinued from the study. All subjects will have scheduled follow up visits 3, 6 (reinjection) 9, and 12 months after the first injection.

Randomization will be done using paper envelopes once eligibility is confirmed.
