Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
AZD0754
AZD0754 monotherapy for treatment of participants with metastatic prostate cancer.
AZD0754
Subjects will undergo leukapheresis to isolate peripheral blood mononuclear cells (PBMCs) to produce AZD0754. During AZD0754 production, subjects may receive bridging therapy for disease control. Upon successful generation of AZD0754 product, subjects will receive treatment with AZD0754 therapy. Study treatment will include lymphodepleting chemotherapy. After lymphodepleting chemotherapy AZD0754 is administered intravenously and patients will be required to stay at the hospital for a protocol specified monitoring period.
AZD2287
AZD2287 is a novel imaging agent for STEAP2
AZD2287
This is an Optional arm of the study, which subjects will separately consent to if they would like to participate. Subjects will receive doses of a radioactive imaging agent called AZD2287 followed by SPECT/CT imaging scans at two time points.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
1. Participant must be 18 years or older at the time of signing the informed consent form.
Type of Participant and Disease Characteristics
2. Participants with:
1. A histologically confirmed diagnosis of metastatic adenocarcinoma of the prostate without known neuroendocrine differentiation or small cell features.
2. Castration-resistant prostate cancer as defined by disease progression despite castration by orchiectomy or ongoing luteinising hormone-releasing hormone analogue. Participants receiving medical castration therapy with gonadotropin releasing hormone analogues should continue this treatment during the study.
3. Measurable PSA \>/=1 ng/mL AND
4. Evidence of progression within 6 months prior to screening according to one of the following:
(i) Radiographic disease progression in soft tissue based on Response Evaluation Criteria in Solid Tumours Version 1.1 criteria with or without PSA progression as per Prostate Cancer Working Group Criteria 3 (PCWG3) (ii) Radiographic disease progression in bone defined as the appearance of 2 or more new bone lesions on bone scan as per Prostate Cancer Working Group Criteria 3 (PCWG3).
(iii) Evidence of disease progression in bone according to PSMA PET scan results in tandem with PSA progression according to PCWG3 criteria."
3. Participant has previously received a NHA (ie, abiraterone, enzalutamide, apalutamide, darolutamide) and a taxane as part of their treatment for prostate cancer (whether before or in the metastatic castration-resistant setting). Participants who are ineligible for taxanes or refuse these therapies may be enrolled at the discretion of the investigator.
4. For participants with pathogenic mutations in BRCA1 or BRCA2, they must also have received a PARP-inhibitor or be intolerant of this therapy. For participants with non-BRCA HRR deficiency disease, treatment with a PARP-inhibitor is at the discretion of the Investigator based on a risk/benefit analysis and discussion with the participant.
5. For participants who have high microsatellite instability or deficient DNA mismatch repair they must also have received at least one line of checkpoint inhibitors (ie, pembrolizumab), not be eligible for, or be intolerant to therapy as per NCCN or local treatment guidelines.
6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 prior to apheresis.
7. Minimum life expectancy of \> 12 weeks prior to apheresis in the opinion of the Investigator
8. Adequate organ and marrow function.
9. Consent and provision of tumour material to assess STEAP2 expression and other correlative biomarkers retrospectively with pre- and post-treatment biopsies. Fresh baseline and on-treatment biopsies are required unless these are deemed medically unfeasible. If the participant is unable to undergo fresh biopsy, an archival tumour sample will be required (age of biopsy cannot be greater than 10 years).
Exclusion Criteria
2. History of another primary malignancy except for malignancy treated with curative intent with no known active disease (≥ 2 years) before the first dose of study intervention and of low potential risk for recurrence. Such exceptions include non-melanoma cancer of the skin that has undergone curative therapy or adequately treated carcinoma in situ without evidence of disease.
3. Participants with known brain metastases.
4. Prior solid organ transplantation.
5. Active or prior documented autoimmune or inflammatory disorders. The following are exceptions to this criterion:
1. Participants with vitiligo or autoimmune alopecia.
2. Participants with autoimmune hypothyroidism (eg, following Hashimoto thyroiditis) stable on hormone replacement.
3. Any chronic inflammatory or autoimmune skin condition that does not require systemic therapy.
4. Participants without active disease in the last 5 years may be included, but only after consultation with the Sponsor.
5. Participants with coeliac disease controlled by diet alone.
6. Stroke, intracranial haemorrhage, or seizure within 6 months of apheresis.
7. Cardiac arrhythmias, (such as multifocal premature ventricular contractions, bigeminy, trigeminy, ventricular tachycardia), which are symptomatic or require treatment (Common Terminology Criteria for Adverse Events \[CTCAE\] Grade 3) unless controlled by pacemaker (discussion with the Study Physician required); symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia.
8. Investigator judgement of one or more of the following:
1. Mean resting corrected QT interval \> 470 ms, obtained from triplicate electrocardiograms (ECGs) performed at screening.
2. History of QT prolongation associated with other medications that required discontinuation of that medication, or any current concomitant medication known to prolong the QT interval and be associated with Torsades de Pointe.
3. Congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first-degree relatives.

Prior/Concomitant Therapy
16. Participants may not receive full-dose long-acting oral (eg, warfarin) or parenteral anticoagulants or thrombolytic agents for therapeutic (as opposed to prophylactic) purpose from the time of informed consent to 28-days post infusion of AZD0754. Use of short acting direct oral anticoagulants (eg, rivaroxaban) for therapeutic and prophylactic purposes are permitted.
17. Received the following:
1. Major surgery within 2 weeks prior to apheresis, or planned major surgery within 4 weeks of the study treatment administration (Note: participants with planned surgical procedures to be conducted under local anaesthesia may participate after discussion with the Sponsor).

18. Receipt of the last dose of anticancer therapy (chemotherapy, immunotherapy, endocrine therapy targeted therapy, biologic therapy, tumour embolisation, or monoclonal antibodies, investigational product) within 5 half-lives or ≤ 21 days (whichever is shorter) prior to apheresis. Radiotherapy within 14 days. However, if the radiation portal covered ≤ 5% of the bone marrow reserve, the participant is eligible irrespective of the end date of radiotherapy. If sufficient washout time has not occurred due to the schedule or PK properties of an agent, a longer washout period will be required, as agreed by AstraZeneca and the Investigator.

Following apheresis, bridging therapy is permitted (if required) as outlined in Section 6.1.2
20. Participants should not have received any live vaccines within 30 days prior to apheresis. Participants can receive coronavirus (COVID)-19 vaccines, at the discretion of the Investigator, following a benefit/risk evaluation for the individual participant and in accordance with local rules and regulations and vaccination guidelines. Note: If a COVID-19 vaccine is administered, it should ideally be done at least one week prior to LDC or after completion of the DLT period.
Prior/Concurrent Clinical Study Experience
