2026년 10월 26일 업데이트: AstraZeneca

AZD4956 단독요법 및 항암제와의 병용요법의 상승 용량에 대한 안전성, 내약성, 약동학, 약력학 및 예비 효능을 평가하기 위한 모듈식 개방형 1상/2a상 임상시험: 진행성/전이성 상동 재조합 수선 결손 고형 종양 환자를 대상으로

The purpose of this modular, first trial in human study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of ascending dose levels (DLs) of AZD4956 monotherapy and in combination with other anti-cancer agents in participants with advanced/metastatic solid tumours with homologous recombination repair (HRR) deficiencies.

상세 설명

The study consists of individual modules each evaluating the safety and tolerability of AZD4956 dosed as monotherapy, or with a specific combination partner. There are following 2 modules -

  1. Module 1: AZD4956 monotherapy
  2. Module 2: AZD4956 in combination with saruparib

Each module may further contain 2 parts-

  • Part A (dose escalation/dose finding): To determine the safety, tolerability, PK, PD, and preliminary efficacy of AZD4956 as monotherapy or in combination.
  • Part B (dose expansion): To further evaluate the safety and preliminary efficacy of AZD4956 in combination with other anti-cancer agents.
