Studie av AZD4956 som monoterapi og i kombinasjon med antikreftmidler hos deltakere med avansert/metastatisk homolog rekombinasjonsdefekt fastvevstumor (PARTHENON)
En modulær åpen, fase I/IIa-studie for å vurdere sikkerhet, tolerabilitet, farmakokinetikk, farmakodynamikk og foreløpig effekt av stigende doser av AZD4956 som monoterapi, og i kombinasjon med antikreftmidler hos deltakere med avansert/metastatisk homolog rekombinasjonsreparasjonsdefekt fastvevstumør
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.

Detaljert beskrivelse
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 -
- Module 1: AZD4956 monotherapy
- 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.
