4. Have been treated with ≥ 1 prior taxane regimens (e.g., docetaxel, cabazitaxel)
5. Are deemed unsuitable for standard of care
Applicable to Part 2, 3a and Part 4a,
1. Have metastatic CRPC, defined by ≥ 1 metastatic lesion that is present on baseline CT, MRI, or bone scan imaging that has documented progressive disease (PD) based on ≥ 1 of the following criteria (per PCWG3):
* PSA level ≥ 1 ng/mL that has increased on ≥ 2 successive occasions ≥ 1 week apart
* Nodal or visceral progression as defined by RECIST v1.1 with PCWG3 modifications
* Appearance of ≥2 new lesions in bone scan
2. Participants with metastatic hormone sensitive prostate cancer (mHSPC) or with biochemical recurrent prostate cancer (BRPC) may also participate in select cohorts of this clinical trial.
You may not be if
1. Presence of dominant histopathological features representative of sarcomatoid, spindle cell, or neuroendocrine small cell components
2. Has acute or chronic infections
3. Has a concomitant medical or inflammatory condition that may increase the risk of toxicity to VIR-5500 (AMX-500), per the Investigator
4. Has lesions in proximity of vital organs
5. Has known active CNS metastases and/or carcinomatous meningitis The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
