ClinicaliQ Trial Snapshot
  • A Study of DS9051b in Participants With Advanced or Metastatic Adrenocortical Carcinoma and Metastatic Castration-resistant Prostate Cancer — Recruiting • Phase I • Oncology • NCT07189403.
  • Drug being tested: DS9051b, a first-in-human (FIH) investigational agent, is being evaluated for safety, tolerability, and early efficacy signals in two aggressive malignancies: advanced/metastatic adrenocortical carcinoma (ACC) and metastatic castration-resistant prostate cancer (mCRPC).
  • Patient eligibility: The study recruits patients with histologically confirmed advanced or metastatic ACC, or mCRPC who have progressed despite standard therapies; specific inclusion/exclusion criteria would define performance status, organ function, and prior treatment requirements.
