TAPS2 Transfusion Antenatally in Pregnant Women With SCD

Status Recruiting

Clinical Trial Summary

Sickle Cell Disease (SCD) is a serious inherited blood disorder affecting red blood cells. When oxygen levels drop the red cells become abnormally shaped and unable to move through the blood vessels easily. Blood and oxygen do not reach body organs, resulting in episodes of severe pain and other complications. Pregnant women with SCD have an increased risk of both sickle and pregnancy complications, including raised blood pressure. Their babies may grow more slowly in the womb, are more likely to be born early and need special care, and have a higher risk of dying. The only treatments currently available for women with SCD are Hydroxycarbamide (which cannot be used during pregnancy) and blood transfusion. Currently, blood transfusion is only used during pregnancy to treat emergency complications. It has been suggested that giving blood transfusions throughout pregnancy could improve outcomes for both mother and babies. In Serial Prophylactic Exchange Blood Transfusion (SPEBT), sickle blood is mechanically removed and simultaneously replaced with donor red cells. A trial is needed to assess SPEBT given every 6-10 weeks, starting before 18 weeks of pregnancy, compared to standard care. This trial will evaluate outcomes for women (e.g. hospital admission, frequency of crisis) and their infants (e.g. early delivery, birthweight). However, the feasibility of such a study needs to be assessed before embarking on a large multicentre trial. This study is therefore a feasibility study in which we will randomly allocate participants to have either SPEBT or standard care. The study will be carried out in multiple maternity units in England and last two years. The willingness of eligible women to join the study will be assessed, along with how many participants remain part of the study until the end and if participants find the intervention acceptable.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
