About this study
Official title: Docetaxel Alone or in Combination With Enzalutamide as First-line Treatment for Metastatic Castration Resistant Prostate Cancer Previously Treated With Abiraterone: a Single Center, Randomized, Open-label Study
New androgen pathway targeting agents (ARTA), including Abiraterone acetate, Apalutamide and Enzalutamide, are approved and used in treatment of metastatic hormonal sensitive prostate cancer(mHSPC). However, the development of castration-resistance prostate cancer(CRPC) is only a matter of time. The use of sequential ARTAs in mCRPC showed limited benefit in retrospective series and prospective trials. Therefore this sequence should be avoided because of known cross resistance and the availability of chemotherapy and poly adenosine diphosphate-ribose polymerase(PARP) inhibitors (if a relevant mutation is present).
Recently, a randomized controlled trial(RCT), the ABIDO-SOGUG, indicated that compared with docetaxel, maintaining Abiraterone added to docetaxel in chemotherapy-naive patients who have experienced cancer progression to Abiraterone treatment could not improve radiographic progression-free survival or the other endpoints.However, another RCT, the PRESIDE trial, indicated that in patients who had progressed on Enzalutamide, continued Enzalutamide treatment in combination with docetaxel led to a significant improvement of PFS compared with placebo plus docetaxel.
The aims of this trial is to assess both the efficacy and safety of docetaxel in combination with Enzalutamide as first-line treatment in mCRPC patients progressed on Abiraterone.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Enzalutamide 40 MG and Docetaxel injection in people with Prostate Cancer and Castrate Resistant Prostate Cancer, run by Zhongnan Hospital at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 28 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
progression-free survival (PFS) (time frame: up to 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2024; AzTrials last refreshed its copy on 6 Nov 2026.
