REGN21353 Alone or in Combination With Nezastomig for Metastatic Castration-Resistant Prostate Cancer in Adult Participants
Phase 1/2 Trial of REGN21353 (a STEAP1xCD3 Bispecific Antibody) Administered Alone or in Combination With Nezastomig (a PSMAxCD28 Bispecific Antibody) in Participants With Metastatic Castration-Resistant Prostate Cancer (mCRPC)
This study will test an experimental Regeneron drug called REGN21353 ("study drug") to see if it can help treat previously treated prostate cancer that has spread (also called metastatic castration-resistant prostate cancer or mCRPC). Some participants may get additional experimental drugs in combination with REGN21353. These additional drugs are nezastomig and sarilumab. "Experimental" means that the drugs are being tested and have not been approved for use in prostate cancer by a country's national health agency that gives approval for new medicines to be prescribed.
The study is looking at:
- What is the best dose of REGN21353 alone and together with nezastomig for treating prostate cancer
- What side effects REGN21353 alone and together with nezastomig might cause
- How well REGN21353 alone and together with nezastomig works
- How much REGN21353 alone and together with nezastomig is in the blood at different times
- If the body reacts to REGN21353 alone or together with nezastomig, in a way that may cause them to not work as well
- How REGN21353 alone and together with nezastomig could affect prostate cancer, which can help researchers understand why REGN21353 alone or together with nezastomig work better in some than others

Popis
Key Inclusion Criteria:
- Is male with histologically or cytologically confirmed adenocarcinoma of the prostate without pure small cell carcinoma
- Has metastatic castration-resistant prostate cancer with prostate-specific antigen value as described in the protocol and that has progressed within 6 months prior to screening
- Has received ≥2 lines of prior systemic therapy approved in the metastatic and/or castration-resistant setting (in addition to androgen deprivation therapy) including at least one androgen receptor pathway inhibitor (eg, abiraterone, enzalutamide, apalutamide, or darolutamide)
- Has had either orchiectomy or be on luteinizing hormone-releasing hormone (LHRH) agonist or antagonist therapy with serum testosterone levels as described in the protocol and agree to stay on LHRH agonist or antagonist therapy during the trial
- Is able and willing to provide tumor tissue, either archival or newly obtained

Key Exclusion Criteria:
- Has not recovered (ie, grade ≤1 or baseline) from immune-mediated adverse event within 3 months prior to initiation of trial intervention therapy except for endocrinopathies adequately managed with hormone replacement
- Has permanently discontinued anti-cancer immune modulating therapies due to immune-mediated adverse events
- Has another malignancy that is progressing or requires active treatment, except non-melanoma skin cancer that has undergone potentially curative therapy or any tumor that has been deemed to be effectively treated with definitive local control
- Has ongoing or recent (within 5 years) evidence of significant autoimmune disease (including any history of systemic vasculitis) that required treatment with systemic immunosuppressive treatments
- Has active liver metastases
- Has current evidence of or history of central nervous system metastases as described in the protocol
- Has encephalitis, meningitis, neurodegenerative disease (with the exception of mild dementia that does not interfere with activities of daily living), or uncontrolled seizures in the year prior to first dose of trial intervention
- Has a known history of, or any evidence of, interstitial lung disease or active, noninfectious pneumonitis (past 5 years). A history of radiation pneumonitis in the radiation field is permitted
