About this study
Official title: Evaluation of the Efficacy and Safety of Adebrelimab and a TKI in Combination With GEMOX in First-line Treatment of Advanced Biliary Tract Cancers (BTC): a Single-arm, Phase II Clinical Study
Patients with advanced biliary tract malignant tumors who had not received systematic treatment before and could not be cured were selected as the subjects of the study. The primary endpoint of the study was investigator-assessed 6-month progression-free survival (6-month PFS%) based on the RECIST v1.1 criteria, and 43 subjects were planned to be enrolled. Patients eligible for enrollment will receive Adebrelimab and a tyrosine kinase inhibitor (TKI) in combination with gemcitabine and oxaliplatin (GEMOX).
Read the detailed description
This is an open-label, single-arm clinical study to observe and evaluate the efficacy and safety of Adebrelimab (PD-L1) and tyrosine kinase inhibitor (TKI) combined with gemcitabine and oxaliplatin (GEMOX) in the first-line treatment of patients with advanced biliary tract malignancies.
Subjects will be screened to receive Adebrelimab and TKI in combination with Gemcitabine and Oxaliplatin (GEMOX) after they are fully informed and sign the informed consent. Study treatment will continue until the subject develops intolerable toxicity, withdraws informed consent, and progresses as determined by the investigator in accordance with RECIST v1.1 (when the subject develops disease progression as defined in RECIST v1.1, if the investigator assesses that the subject continues to have clinical benefit and can tolerate the study treatment, The subject may continue treatment with the study drug; treatment may be terminated if the subject is no longer considered to have a clinical benefit), or other termination criteria specified in the protocol, whichever occurs first.
After the subjects were enrolled in the study, the safety visit will be conducted in D1 of each treatment cycle, and the safety visit and survival follow-up will be continued after the treatment.
Tumor imaging evaluation Imaging examination was performed every 6 weeks after enrollment to evaluate the efficacy. Additional imaging studies and evaluations may be performed at any time during the study if clinically indicated. Imaging evaluation of the tumor will continue until disease progression is confirmed by the investigator according to the RECIST v1.1 criteria or treatment is discontinued, whichever occurs later. Subjects who ended treatment for reasons other than investigator-confirmed disease progression (per RECIST v1.1) will also continue to be followed up at regular intervals for tumor imaging evaluation after the end of treatment.
If the subject withdraws the knowledge, has started other anti-tumor treatment (except Chinese patent medicine) or dies before the disease progression or termination of treatment confirmed by the investigator according to RECIST1.1 criteria, there is no need to continue the imaging evaluation. If the subject fails to meet the above termination criteria for imaging evaluation, the tumor efficacy evaluation of other efficacy evaluation criteria (RECIST v1.1, imRECIST) still needs to be continued even if the disease progression of a certain efficacy evaluation criteria occurs.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Adebrelimab + GEMOX + TKI in people with Biliary Tract Cancer and Gemox Chemotherapy, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site 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 15 inclusion and 27 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 20 Mar 2024. 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 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. 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 Wenbin Li, archiater (86-13602773101, gzsurgeon@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the effectiveness of first-line treatment with Adebrelimab and a tyrosine kinase inhibitor (TKI) in combination with gemcitabine and oxaliplatin (GEMOX) in patients with advanced BTC (time frame: From enrollment 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 20 Mar 2024.
