Een studie van apalutamide bij deelnemers met risicovolle, gelokaliseerde of lokaal gevorderde prostaatkanker die in aanmerking komen voor radicale prostatectomie (PROTEUS)

2 november 2026 bijgewerkt door: Janssen Research & Development, LLC

Een gerandomiseerde, dubbelblinde, placebogecontroleerde, fase 3-studie van apalutamide bij proefpersonen met hoog-risico, gelokaliseerde of lokaal gevorderde prostaatkanker die in aanmerking komen voor radicale prostatectomie

The purpose of this study is to determine if treatment with apalutamide plus androgen deprivation therapy (ADT) before and after radical prostatectomy (RP) with pelvic lymph node dissection (pLND) in participants with high-risk localized or locally advanced prostate cancer results in an improvement in pathological complete response (pCR) rate and metastasis-free survival (MFS) as compared to placebo plus ADT.

  • Candidate for radical prostatectomy with pelvic lymph node dissection as per the investigator
  • Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1
  • Contraceptive use by male participants (and female partners of male participants enrolled in the study who are of childbearing potential or are pregnant) should be consistent with local regulations regarding the use of contraceptive methods for participants participating in clinical studies
  • Able to receive androgen deprivation therapy (ADT) for at least 13 months

Exclusion Criteria:

  • Distant metastasis based on conventional imaging (clinical stage M1). Nodal disease below the iliac bifurcation (clinical stage N1) is not an exclusion. Diagnosis of distant metastasis (clinical M stage; M0 versus M1a, M1b, M1c) and pelvic nodal disease (clinical N stage; N1 versus N0) will be assessed by central radiological review. Participants are considered eligible only if the central radiological review confirms clinical stage M0

  • History of prior systemic or local therapy for prostate cancer, including pelvic radiation for prostate cancer
  • Use of any investigational agent less than or equals to (<=)4 weeks prior to randomization or any therapeutic procedure for prostate cancer at any time
  • Major surgery <=4 weeks prior to randomization
  • Any of the following within 12 months prior to first dose of study drug: severe or unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events (example, pulmonary embolism, cerebrovascular accident including transient ischemic attacks), or clinically significant ventricular arrhythmias or New York Heart Association Class II to IV heart disease; uncomplicated deep vein thrombosis is not considered exclusionary

Interventie / Behandeling
Experimenteel: Apalutamide + ADT

Participants will receive androgen deprivation therapy (ADT) plus oral administration of apalutamide 240 milligram (mg) (4 tablets of 60 mg each) daily in each cycle (each cycle of 28 days). Participants will receive six cycles of treatment, followed by radical prostatectomy (RP) with pelvic lymph node dissection (pLND), followed by an additional six cycles of treatment. A Long-Term Extension (LTE) may be initiated at sponsor's discretion after completion of the primary endpoint analysis.

Participants will receive apalutamide 240 mg (4 tablets of 60 mg each) orally once daily.

Andere namen:
  • JNJ-56021927

Participants will receive a stable regimen of ADT - gonadotropin-releasing hormone analog (agonist or antagonist) (GnRHa). ADT is a kind of hormone therapy for prostate cancer. GnRHa will be administrated to achieve and maintain sub-castrate concentrations of testosterone (50 nanogram per deciliter [ng/dL]).

Experimenteel: Placebo + ADT

Participants will receive ADT with oral administration of matching placebo treatment daily in each cycle (each cycle of 28 days). Participants will receive six cycles of placebo treatment, followed by RP with pLND, followed by an additional six cycles of placebo treatment. A LTE may be initiated at sponsor's discretion after completion of the primary endpoint analysis.
