Study of Ceftriaxone and Benzathine Penicillin G During Pregnancy

Официальное название

Phase IV Study of the Pharmacokinetics and Safety of Ceftriaxone and Benzathine Penicillin G During Pregnancy

Обзор

IMPAACT 2044 is a study to characterize the pharmacokinetics (PK) and safety of ceftriaxone and benzathine penicillin G during pregnancy. Up to 78 pregnant women receiving (1) ceftriaxone for indications other than syphilis or (2) benzathine penicillin G for treatment of syphilis from non-study clinical care providers will be enrolled at study sites located in the United States. Approximately 22 infants of pregnant participants receiving benzathine penicillin G will also be enrolled.

Подробное описание

IMPAACT 2044 is a Phase IV, multi-site, open-label, non-randomized, opportunistic study to characterize the pharmacokinetics (PK) and safety of ceftriaxone and benzathine penicillin G during pregnancy.

The study includes two arms, with Arm 1 subdivided by route of administration:

Arm 1A: Intravenous (IV) ceftriaxone Arm 1B: Intramuscular (IM) ceftriaxone Arm 2: IM benzathine penicillin G

Вмешательства

• Препарат Ceftriaxon
  Ceftriaxone will not be provided as part of the study. Pregnant participants will receive these drugs as prescribed outside the study by their non-study clinical care provider
• Препарат Benzathine penicillin G
  Benzathine penicillin G will not be provided as part of the study. Pregnant participants will receive these drugs as prescribed outside the study by their non-study clinical care provider
