About this study

Official title: Efficacy and Safety of Socazolimab Combined With Chemotherapy With or Without Bevacizumab as First-Line Treatment in Persistent, Recurrent, or Metastatic Cervical Cancer: A Randomized, Double-blind, Placebo-controlled Phase III Study

The goal of this clinical trial is to evaluate the efficacy and safety of Socazolimab combined with chemotherapy with or without bevacizumab as first-Line treatment in persistent, recurrent, or metastatic cervical cancer. The main question it aims to answer is:

Does Socazolimab combined with chemotherapy with or without bevacizumab better benefit patients with persistent, recurrent, or metastatic cervical cancer as first-line treatment compared with placebo combined with chemotherapy with or without bevacizumab.

Participants will be treated with Socazolimab/placebo + chemotherapy ± bevacizumab) for 6~8 cycles (Q3w), following maintenance treatment of Socazolimab/placebo (Q3w).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Socazolimab+cisplatin/carboplatin+paclitaxel+Bevacizumab in people with Cervical Cancer, run by Lee's Pharmaceutical Limited at 5 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 9 inclusion and 29 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: looking for participants now, as of the sponsor's last update on 14 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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 phase mean?

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?

This study is still under way. Results are not available in the source record yet.

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?

Overall survival (time frame: From date of randomization to date of death from any cause, assessed up to 100 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 14 May 2025.
