Clinical Trials

Atosiban has been investigated in numerous clinical trials spanning Early Phase 1 through Phase 4 studies. These evaluations, supported by both academic institutions such as Radboud University Medical Center and pharmaceutical sponsors like GlaxoSmithKline, encompass recruitment statuses ranging from recruiting and completed to terminated. Research primarily focuses on obstetric and gynecological conditions, including premature labor in single and multiple gestations, female infertility, repeated implantation failure, and endometriosis-associated pain. For instance, trials such as NCT02725736 assess tocolytic efficacy in preterm gestations, whereas studies like NCT05382143 and NCT02893722 explore its utility in endometriosis and implantation failure.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Atosiban acts as a competitive antagonist with high affinity for oxytocin and vasopressin V1a receptors, thereby inhibiting receptor-mediated intracellular calcium mobilization and phosphoinositide signaling in myometrial cells. This pathway blockade suppresses uterine smooth muscle contractility and tone, reducing premature uterine contractions to support clinical management in preterm labor and reproductive disorders.
