Men Living With Prostate Cancer

Not an actual patient.

About CONTACT•02

CONTACT•02 is a Phase 3 clinical trial for men who have an advanced stage of prostate cancer called metastatic castration-resistant prostate cancer (mCRPC). The first step is to talk to your doctor about whether you are eligible to participate.

Men who are able to participate in the study will be assigned to one of two groups. Each group will receive different study drugs for their prostate cancer:

  • Group A will receive a combination of two drugs: cabozantinib and atezolizumab
  • Group B will receive either a drug called abiraterone acetate together with prednisone or a drug called enzalutamide

The trial will compare Groups A and B to see whether these study drugs help men with mCRPC to live longer without their disease getting worse.

Throughout the trial, each participant’s cancer will be measured with scans, such as CT (or MRI) and also bone scans.

CONTACT•02 has additional goals, including understanding the safety of cabozantinib plus atezolizumab, and what kind of side effects the two study drugs cause.

Trial Design

Men who are able to participate in the study will be randomly assigned, 1:1, to one of two groups. Each group will receive different study drugs for their prostate cancer.

Group A

Participants will receive a combination of two study drugs: cabozantinib and atezolizumab.

Group B

Participants will receive either a drug called abiraterone acetate (together with prednisone) or a drug called enzalutamide.

If you are assigned to Group B, your study doctor will choose which drug is appropriate for you.
