About this study

Official title: An Open Label, Single Arm, Safety Lead-in, Multicenter, Investigator Initiated Trial of Combination of Durvalumab , An Immune Checkpoint Inhibitor, and BVAC-C, A Cell-based Immunotherapeutic Vaccine, in Patients With HPV 16 or 18 Positive Cervical Cancer Failure to First-Line Platinum-based Chemotherapy

This is an exploratory, open label, multi-center trial to evaluate the safety and efficacy of combination of durvalumab with BVAC-C in patients with cervical cancer refractory to or relapse after platinum-based first-line chemotherapy with safety lead-in phase.

The study consists of 2 parts: part A, a safety lead-in phase, and part B, an exploratory safety and efficacy evaluation phase.

Part A will be conducted as a 3+3 dose escalation manner, and part B will be conducted as a non-randomized single arm study.

•Part A: Open-labeled; 3+3 dose-escalation; Multi-center; safety lead-in phase

•Part B: Open-labeled; Non-randomized, Single arm; Multi-center, efficacy evaluation phase

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BAVC-C+Durvalumab in people with Cervical Cancer, run by Samsung Medical Center.

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 22 inclusion and 39 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 16 Mar 2021. 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?

Results are not available in the source record.

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

Contact ByoungGie Kim (+82-02-3410-3513, bgkim@skku.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part A : Dose-limiting toxicities(DLTs) (time frame: up to 11 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 16 Mar 2021.
