건강한 수유 여성의 약(PF-07321332 또는 Nirmatrelvir/Ritonavir)에 대해 알아보기 위한 연구

2026년 4월 28일 업데이트: Pfizer

수유 중인 건강한 여성을 대상으로 한 NIRMATRELVIR/RITONAVIR의 I상, 다회 투여, 공개 약동학 연구

이 연구의 주요 목적은 건강한 모유 수유 여성에게 주어졌을 때 인간 모유에서 분비되는 연구 약물(nirmatrelvir)의 활성 성분 수준을 측정하는 것입니다. 연구 약물은 니르마트렐비르와 리토나비르의 두 가지 약물로 구성됩니다. 다음과 같은 여성 참가자를 모집합니다.

  • 산후 최소 12주 동안 적극적으로 모유 수유(수유);
  • 18세에서 55세 사이이고 현재 임신하지 않은 연령;
  • 체질량 지수(BMI): 17.5kg/m2 총 체중 >50kg(110lb).

참가자는 연구 클리닉에서 2일에 걸쳐 총 3회(오전 2회 및 저녁 1회) 경구로 연구 약을 복용하게 됩니다. 2일에서 4일 사이에 정기적으로 모유를 채취하여 그 안에 있는 니르마트렐비르와 리토나비르의 수치를 측정합니다. 참가자가 연구 약물에 대해 가질 수 있는 모든 반응을 모니터링하기 위해 마지막 투여로부터 약 28-35일 후에 안전성 후속 전화가 실시됩니다.

An adverse event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. AEs might arise from symptoms or other complaints reported to the investigator by the participant (or, when appropriate, by a caregiver, surrogate, or the participant's legally authorized representative), or they might arise from clinical findings of the investigator or other healthcare providers (clinical signs, test results, etc.). TEAEs were those with initial onset or increasing in severity after the first dose of study treatment.
