About this study
Official title: Randomized Phase II/III Trial to Assess the Efficacy of Platinum-based Chemotherapy vs Standard Non-platinum Therapy in Patients With Platinum-resistant Recurrent Ovarian Cancer (ROC)
This is a phase II/III randomized controlled trial to evaluate efficacy of platinum-based chemotherapy vs conventionally prescribed non-platinum monochemotherapy in patients with platinum-resistant ovarian cancer
Read the detailed description
Recurrent ovarian cancer (ROC) is usually subdivided to platinum-sensitive (platinum-free interval [PFI] ≥6 mo.) and platinum-resistant ovarian cancer [PROC] (PFI <6 mo.) subtypes. Prognosis for the latter group is dismal and current guidelines recommend treating these patients with non-platinum based chemotherapy. However, the evidence behind this is quite unconvincing and according to recent data patients with non-platinum refractory platinum-resistant ovarian cancer could derive benefit from platinum rechallenge. This trial is designed for head-to-head comparison of platinum and non-platinum therapy efficacy in treatment of platinum-resistant ovarian cancer.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Platinum-Based Drug and Conventional chemotherapy in people with Ovarian Cancer and Ovarian Neoplasms, run by Blokhin's Russian Cancer Research Center at 1 site in Russia.
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 17 inclusion and 13 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 13 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Russia. 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. 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?
Contact Alexey Rumyantsev, MD (+79100022255, alexeymma@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Objective response rate (RR) according to RECIST 1.1 criteria (time frame: 0-18 weeks). The study lists 2 primary outcomes in all. 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 13 Aug 2019; AzTrials last refreshed its copy on 8 Nov 2026.
