SARS-CoV-2 and Acetylsalicylic Acid (SARA) (SARA)

August 14, 2024 updated by: Barcelona Institute for Global Health

Efficacy of Low Dose Acetylsalicylic Acid in Preventing Adverse Maternal and Perinatal Outcomes in SARS-CoV-2 Infected Pregnant Women

SARS-CoV-2 infection in pregnancy is associated with an increased risk of adverse maternal and perinatal outcomes. One explanation is that the infection might increase the existing pregnancy-associated prothrombotic status, leading to a higher risk of placental and vascular complications. Administration of low-dose acetylsalicylic acid (LDASA) has shown to improve maternal and perinatal outcomes in women at high-risk of endothelial and placental complications. However, there are no data on the effect of LDASA in preventing complications in SARS-CoV-2- infected pregnant women. To reduce SARS-CoV-2- related complications in a highly vulnerable group to the infection, we will carry out this randomized, double-blind, placebo-controlled multicentre trial in 400 SARS-CoV-2-infected pregnant women. The study main objective is to evaluate the efficacy and safety of LDASA administered up to 36 weeks of gestation in SARS-CoV-2-infected pregnant women in reducing the incidence of adverse maternal and perinatal outcomes. Pregnant women tested positive up to 32 weeks of gestation with a SARS-CoV-2 rapid antigen or PCR test and agreeing to participate, will be randomised 1:1 to receive daily LDASA (125 mg) or placebo up to 36 weeks of gestation and be followed-up until delivery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
