About this study

Official title: A Randomized Phase II Study to Investigate the Efficacy of Rotations Between Abiraterone Acetate and Apalutamide Versus Sequential Administration in Chemo-naïve Metastatic Castration Resistant Prostate Cancer Patients

A randomized phase II study comparing the sequential use of abiraterone followed after progression by apalutamide with alternating cycles of abiraterone and apalutamide

Read the detailed description

This is an open-label, randomized phase II study to investigate the feasibility of alternating cycles of treatment with abiraterone plus prednisone and apalutamide compared to sequential treatment of abiratereone plus prednisone followed by apalutamide. 7 centers in Greece will participate in the study.

The study population consists of adult patients (over 18 years old) with histologically confirmed metastatic prostate adenocarcinoma who have disease progression - as defined by PCWG2 criteria - despite androgen deprivation therapy and who have not received prior therapy for their castration resistant disease.

The purpose of the study is to determine the progression free survival, feasibility and safety profile of the experimental arm compared to standard of care.

In the experimental arm alternating treatment will consist of repeating cycles of 24 weeks of treatment consisting of 12 weeks of abiraterone acetate 1000mg orally qd and prednisone 5mg orally bid, followed by 12 weeks of apalutamide 240 mg per day. There will be no wash out period between cycles.

The comparative arm will be the standard regimen of abiraterone 1000mg orally qd plus prednisone 5mg orally bid until progression, followed thereafter by apalutamide 240mg orally qd until progression.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Abiraterone and Apalutamide in people with Prostatic Neoplasms, Castration-Resistant, run by University of Athens.

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 15 inclusion and 5 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The record says: withdrawn, as of the sponsor's last update on 18 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this 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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Radiographic progression-free survival (time frame: Estimated up to 24 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 18 Nov 2020.
