This research study is studying a new compound, AZD8205, as a possible treatment for advanced or metastatic solid tumours alone or in combination with anti-cancer agents
Interventions
DRUG
AZD8205
AZD8205 is an antibody drug conjugate that has the potential to treat a wide variety of solid tumors including but not limited to breast cancer, Biliary Tract Cancer, ovarian, endometrial cancers and squamous non-small cell lung cancers.
DRUG
AZD8205 and AZD2936 (Rilvegostomig)
AZD8205 is an antibody drug conjugate that has the potential to treat a wide variety of solid tumors including but not limited to breast cancer, Biliary Tract Cancer, ovarian, endometrial cancers and squamous non-small cell lung cancers. Rilvegostomig is a bispecific antibody that specifically binds to human TIGIT and PD-1 and is a potential anticancer therapy in patients with advanced or metastatic solid tumors.
DRUG
AZD8205 and AZD5305 (saruparib)
AZD8205 is an antibody drug conjugate that has the potential to treat a wide variety of solid tumors including but not limited to breast cancer, Biliary Tract Cancer, ovarian, endometrial and squamous non-small cell lung cancers. Saruparib is a PARP inhibitor that stops the PARP protein from doing its repair work in damaged cancer cells, resulting in cell death, and is a potential anticancer therapy in patients with advanced or metastatic solid tumors.

DRUG
AZD8205 in combination with AZD9574
AZD8205 is an antibody drug conjugate that has the potential to treat a wide variety of solid tumors including but not limited to breast cancer, Biliary Tract Cancer, ovarian, endometrial and squamous non-small cell lung cancers. AZD9574 is a PARP inhibitor that stops the PARP protein from doing its repair work in damaged cancer cells, resulting in cell death, and is a potential anticancer therapy in patients with advanced or metastatic solid tumors.
DRUG
AZD8205 in combination with AZD9574 plus rilvegostomig (AZD2936)
AZD8205 is an antibody drug conjugate that has the potential to treat a wide variety of solid tumors including but not limited to breast cancer, Biliary Tract Cancer, ovarian, endometrial and squamous non-small cell lung cancers. AZD9574 is a PARP inhibitor that stops the PARP protein from doing its repair work in damaged cancer cells, resulting in cell death, and is a potential anticancer therapy in patients with advanced or metastatic solid tumors.

Primary outcome measures
The number of patients with adverse events
Time frame: From time of Informed consent to 30 days post last dose (approximately 1 year).
Number of patients with adverse events by system organ class and preferred term
The number of patients with serious adverse events
Time frame: From time of Informed consent to 30 days post last dose (approximately 1 year)
Number of patients with serious adverse events by system organ class and preferred term
The number of patients with dose-limiting toxicity (DLT), as defined in the protocol.
Time frame: From first dose of study treatment until the end of Cycle 1 (approximately 21 days).
A DLT is defined as any toxicity that occurs from the first dose of study treatment 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 and which includes pre-defined haematological and non-haematological toxicities.
The number of patients with changes from baseline laboratory findings, ECGs and vital signs
Time frame: From time of informed consent to 30 days post last dose (approximately 1 year)
Description of laboratory findings and vital signs variables over time including change from baseline.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age ≥ 18 years

- Measurable disease per RECIST v1.1
- Eastern Cooperative Oncology Group (ECOG) Performance Status: 0-1
- Life expectancy ≥ 12 weeks
- Adequate bone marrow, hepatic, and renal function as defined in the protocol Additional Inclusion Criteria For Sub-Study 1 Part A: • Histologically or cytologically confirmed metastatic or locally advanced/recurrent breast cancer, ovarian cancer, BTC or endometrial cancer Additional Inclusion Criteria For Sub-Study 1 Part B:

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
