RC48 Monotherapy or Combination With Envafolimab for CDK12 Alterations mCRPC With Standard Treatment Failure
Is NCT06663007 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including RC48 and Envafolimab for prostate cancer.
Treatment: RC48 · Envafolimab — The aim of this study is to evaluate the efficacy and safety of vediximab monotherapy or in combination with enrolizumab for second-line treatment of CDK12 alterations mCRPC that has failed standard therapy. The research results are expected to provide new insights and breakthroughs for the treatment of advanced prostate cancer.
