The disclosure provides compositions and methods for determining the propensity of a subject (e.g., a female human subject) undergoing embryo transfer therapy to benefit from administration of an oxytocin receptor antagonist, as well as for treating such patients accordingly. Using the compositions and methods of the disclosure, a subject undergoing embryo transfer therapy may be selected for treatment with an oxytocin receptor antagonist on the basis of a pre-treatment gene signature. Additionally or alternatively, a subject that is undergoing embryo transfer therapy and that has been administered an oxytocin receptor antagonist may be monitored following treatment to determine whether the subject is responding to the oxytocin receptor antagonist or if subsequent dosing is desirable. Exemplary oxytocin receptor antagonists useful in conjunction with the compositions and methods of the disclosure include pyrrolidin-3-one oxime compounds, such as (3Z,5S)-5-(hydroxymethyl)-1-[(2'-methyl- 1,1'-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime, among others.
本发明提供了用于确定接受胚胎移植治疗的受试者(例如女性受试者)是否有从使用催产素受体拮抗剂治疗中获益的倾向的组合物和方法,以及相应地治疗这些患者的方法。利用本发明的组合物和方法,可基于预处理基因签名选择接受胚胎移植治疗的受试者进行催产素受体拮抗剂治疗。此外,也可以在给予催产素受体拮抗剂治疗后,对接受胚胎移植治疗的受试者进行监测,以确定受试者是否对催产素受体拮抗剂做出反应或是否需要随后的剂量。本发明的组合物和方法中有用的催产素受体拮抗剂包括吡咯烷-3-酮肟化合物,例如(3Z,5S)-5-(羟甲基)-1-[(2'-甲基-1,1'-联苯基)羰基]吡咯烷-3-酮-O-甲氧基肟等。
