To qualify for the study, you will go through a screening process that may include questions about your medical history, blood tests, a CT or MRI, bone scan, and a physical exam. Check out the criteria below to see if you might be a candidate.

See if you may qualify

You or your loved one can join the study if:

  • You are 18 years of age or older  
  • You have been diagnosed with hormone-resistant prostate cancer that has spread to other parts of your body (metastasized), but not to the brain 
  • You have been treated with at least 1 oral hormone therapy but no more than 2 different oral hormone therapies (abiraterone, enzalutamide, apalutamide, and darolutamide)  
     
    There are other requirements to participate. The clinical staff will give you more information. 

You or your loved one cannot join the study if:

  • You have had a solid organ or bone marrow transplant 
  • You have an autoimmune disease (where your immune system attacks your body) and are taking medications to suppress your immune system 
  • You have another cancer, other than prostate cancer, that might interfere with the study results 
  • You’ve had serious heart or stroke problems in the last 6 months 
     
    There are other requirements to participate. The clinical staff will give you more information.
What to Expect as a Participant

The study includes 3 periods: Screening, Treatment, and Follow-up  

Screening Period: During the Screening period, you will have tests and procedures, including imaging/scans, to see if you qualify for the study. The study doctor will answer any questions you may have and ask you to sign an Informed Consent Form (ICF) before any study-related procedures.  

Treatment Period: If you qualify, you will be randomly assigned to get either the investigational medication with chemotherapy or chemotherapy alone. Both are given by IV infusion over 30 to 60 minutes. This is an open-label study, meaning that you and the clinical staff will know if you are receiving the investigational medication with chemotherapy or chemotherapy alone.  

The study schedule is broken out into groups of weeks that repeat, called cycles. All cycles are 6 weeks, except for Cycle 1 (8 weeks) for patients receiving the investigational medication with chemotherapy.*   

Follow-up Period: The Follow-up period starts after the end-of-treatment visit and is broken into two parts – post-treatment follow-up and survival follow-up. Your study doctor will let you know when your treatment period ends, and when your end-of-treatment visit will be. Follow-up visits are every 6-12 weeks and may be done at the clinic or on the phone, depending on the phase of follow-up. Follow-up visits help us collect useful long-term information about these treatments on you and your disease.
