This research is designed to determine if experimental treatment with PARP inhibitor, AZD5305, alone, or in combination with anti-cancer agents is safe, tolerable, and has anti-cancer activity in patients with advanced solid tumors.

This study is a Phase I/IIa modular, open-label, multi-center study of AZD5305 administered orally, either as monotherapy or in combination with other anti-cancer agents in patients with advanced solid malignancies.

The study consists of individual modules each evaluating the safety and tolerability of AZD5305 dosed as monotherapy, or with a specific combination partner:

* Module 1 (AZD5305 monotherapy)
* Module 2 (AZD5305 in combination with paclitaxel)
* Module 3 (AZD5305 in combination with carboplatin, with or without paclitaxel)
* Module 4 (AZD5305 in combination with T DXd)
* Module 5 (AZD5305 in combination with Dato-DXd).
* Module 6 (AZD5305 in combination with Camizestrant)

Modules 1 and 4 has 2 study parts: Part A consisting of dose-escalation cohorts and Part B, consisting of expansion cohorts. Modules 2, 3, 5 and 6 have only PART A.

Study of AZD5305 as Monotherapy and in Combination With Anti-cancer Agents in Patients With Advanced Solid Malignancies

A Modular Phase I/IIa, Open-label, Multicentre Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of Ascending Doses of AZD5305 as Monotherapy and in Combination With Anti-cancer Agents in Patients With Advanced Solid Malignancies

Number of patients with adverse events and with serious adverse events including abnormal clinical observations, abnormal ECG parameters, abnormal laboratory assessments and abnormal vital signs that changed from baseline

A DLT is defined as any toxicity that occurs from the first dose of study treatment (either AZD5305 or combination anti-cancer agent) up to and including the planned end of Cycle 1 (the DLT assessment period) that is assessed as unrelated to the disease or disease-related processes under investigation. DLTs occurring outside the DLT window (ie, late onset toxicities) may be defined as a DLT after consultation with the sponsor and investigators, based on the emerging safety profile.

Change in target lesion size from baseline, as defined by RECIST 1.1.

Best response until progression, as defined by RECIST 1.1.

Time from first response to progression or death , as defined by RECIST 1.1.

Time from C1D1 to complete or partial response, as defined by RECIST 1.1.

at least a 50% reduction in CA125 levels from a pre-treatment sample as defined by GCIG criteria.

The concentration of AZD5305 in plasma will be determined. Area under the curve is the integral of the concentration-time curve. The AUC reflects the actual body exposure to drug after administration. The AUC is dependent on the rate of elimination of the drug from the body and the dose administered.

The concentration of AZD5305 in plasma will be determined (Cmax will be derived).

The concentration of AZD5305 in plasma will be determined (Tmax will be derived).
