Studie přípravku AZD4956 jako monoterapie a v kombinaci s protinádorovými přípravky u účastníků s pokročilými/metastatickými solidními nádory s deficitem homologní rekombinace (PARTHENON)

26. října 2026 aktualizováno: AstraZeneca

Modulární otevřená studie fáze I/IIa pro posouzení bezpečnosti, snášenlivosti, farmakokinetiky, farmakodynamiky a předběžné účinnosti rostoucích dávek přípravku AZD4956 jako monoterapie a v kombinaci s protinádorovými látkami u účastníků s pokročilými/metastatickými solidními nádory s defektem homologní rekombinační reparace

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.

Detailní popis

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.
