The purpose of this study is to determine the safety and optimal dosing of intravenous copper chloride and disulfiram in men with metastatic castrate-resistant prostate cancer (CRPC). Eligible men will have neuroendocrine prostate cancer (NEPC), adenocarcinoma CRPC with non-liver/peritoneal metastases (lymph nodes, bone, or lung) or adenocarcinoma CRPC with liver and/or peritoneal metastases. Subjects will receive three doses of intravenous copper chloride and take disulfiram and oral copper gluconate until disease progression (up to two years). Subjects will also undergo a PET scan with radioactive copper 64 to measure the levels of copper in their tumor. The central hypotheses of this project are that (a) copper chloride and disulfiram are safe to give together and that (b) the combination of disulfiram with copper will have efficacy for both mCRPC and NEPC.

The purpose of this study is to evaluate the change in the expression of treatment targets on the surface of tumor cells (Prostate Specific Membrane Antigen (PSMA), Somatostatin Receptor 2 (SSTR2), and Gonadotropin Releasing Hormone Receptor (GRPR)) between the start and after the completion of radioligand therapy (RLT). Study will use radioligand imaging (RLI) to determine predominantly expressed target on the surface of tumor cells. Based on predominant expression of target, corresponding RLT targeting PSMA, SSTR2, or GRPR RLT will be given for up to 6 cycles every 6 weeks as intravenous (i.v.) injection in participants with metastatic neuroendocrine prostate cancer (mNEPC).

The screening period for each subject includes imaging with 3 radioligand imaging (RLI) compounds to assess expression level of PSMA, SSTR2 and GRPR. Participants will be assigned to the radioligand treatment (RLT) corresponding to their predominantly expressed target based on blinded independent central review (BICR). During the treatment period, participants will receive up to 6 cycles of the assigned RLT, corresponding to a total dose of 44.4 GBq (+/-10%) for \[177Lu\]Lu-PSMA-617 or \[177Lu\]Lu-DOTA-TATE , and 55.5 GBq (+/-10%) for \[177Lu\]Lu-NeoB. No crossover to a different type of RLT is allowed.

At end of treatment (EoT) with RLT, participants will be scanned again with the 3 RLIs. All EoT PET/CT scans should be performed using the same PET/CT camera, acquisition and reconstruction protocols as used for screening PET/CT for the participant.

The post-treatment follow-up period consists of a 42-days post EoT safety follow-up visit and long-term follow-up until radiographic disease progression, death, lost to follow-up or withdrawal of consent, whichever occurs first.

The planned duration of treatment is up to 36 weeks for all treatment arms in this study, with treatment given every 6 weeks. Participants may be discontinued from treatment earlier due to unacceptable toxicity or disease progression, and/or at the discretion of the Investigator or the participant.

Participants will be assigned to a treatment arm based on their predominantly expressed target per PET images (based on central read):

* \[177Lu\]Lu-PSMA-617 will be assigned to those with predominant PSMA expression
* \[177Lu\]Lu-DOTA-TATE will be assigned to those with predominant SSTR2 expression
* \[177Lu\]Lu-NeoB will be assigned to those with predominant GRPR expression

Participants must have metastatic prostate cancer

NEPC Study: An Exploratory Safety and Efficacy Study With PSMA, SSTR2 and GRPR Targeted Radioligand Therapy in Metastatic Neuroendocrine Prostate Cancer.

A Phase I, Open-label, Multi-center Exploratory Safety and Efficacy Study With PSMA, SSTR2 and GRPR Targeted Radioligand Therapy in Metastatic Neuroendocrine Prostate Cancer.

Number/extent of lesions with at least a moderate update of any of the RLIs according to visual assessment scoring scale on each corresponding targeted PET/CT scan based on blinded independent central review (BICR) assessment.

Percentage changes in qualitative PET parameters (SUVmax, SUVmean, SUVpeak, target-positive Tumor Volume (target -TV), Total Lesion (target (TL-target)\] and changes in number of target-positive lesions (as per visual assessment) on each corresponding target PET/CT based on BICR.

Overall Response Rate (ORR) is defined as the proportion of participants with the best overall response (BOR) of confirmed complete response (CR) or partial response (PR) based on Prostate Cancer Working Group 3 (PCWG3) modified-RECIST v1.1.

Disease Control Rate (DCR) is defined as the proportion of participants with BOR of CR, PR, stable disease (SD), or non-CR/non-PD based on PCWG3 modified-RECIST v1.1.

Duration of response (DOR) is defined as the time (in months) from the date of the first confirmed response (CR or PR) to the date of first documented progression according to PCWG3 modified-RECIST v1.1 or death due to any cause, among participants with a confirmed response.

Radiographic Progression-free Survival (rPFS) is defined as the time from the date of first dose of study treatment to the date of first documented radiographic progression (as assessed by the local investigator and using PCWG3 modified-RECIST v1.1 criteria) or death due to any cause.

The PSA analysis will investigate the proportion of participants with a decline in PSA level from baseline to each visit.

The distribution of adverse events for Radioligand Therapy (RLT) will be done via the analysis of frequencies for Adverse Event (AEs) and Serious Adverse Event (SAEs) through the monitoring of relevant clinical and laboratory safety parameters.

Adverse event monitoring should be continued for at least 42 days following the end of treatment (EOT) visit.

Participants receiving the study treatment \[68Ga\]Ga-DOTA-TATE/\[177Lu\]Lu-PSMA-617 or \[177Lu\]Lu-NeoB will continue to be followed for safety every 12 weeks during the long-term follow-up for selected adverse events.

Dose modifications (dose interruptions, dose discontinuations and reductions) for \[177Lu\]Lu-PSMA-617, \[177Lu\]Lu-DOTA-TATE and \[177Lu\]Lu-NeoB will be assessed and summarized using descriptive statistics.

The distribution of adverse events for Radioligand Imaging (RLI) will be done via the analysis of frequencies for Adverse Event (AEs) and Serious Adverse Event (SAEs) through the monitoring of relevant clinical and laboratory safety parameters.
