Study Overview

Adebrelimab in Combination With NALIRIFOX in Locally Advanced Pancreatic Cancer

In this study, Adebrelimab combined with NALIRIFOX conversion therapy was performed in subjects with locally advanced pancreatic cancer to evaluate the efficacy and safety of conversion therapy with immunotherapy combined with chemotherapy, followed by different treatment methods such as surgery, continued conversion therapy, and advanced systemic therapy according to different transformation outcomes, to improve the survival benefit of subjects with locally advanced pancreatic cancer.

In this study, Adebrelimab combined with NALIRIFOX conversion therapy was performed in subjects with locally advanced pancreatic cancer to evaluate the efficacy and safety of conversion therapy with immunotherapy combined with chemotherapy, followed by different treatment methods such as surgery, continued conversion therapy, and advanced systemic therapy according to different transformation outcomes, to improve the survival benefit of subjects with locally advanced pancreatic cancer. To assess the surgical resection conversion rate of chemotherapy in addition to immunotherapy for unresectable locally advanced pancreatic cancer (LAPC). To evaluate the changes in CA19-9 levels, objective response rate (ORR), R0/R1 resection rate, pathologic response (pCR/MPR), event-free survival (EFS), 1 year and 2 years and overall survival (1y-OS, 2y-OS, OS) before and after conversion therapy for unresectable locally advanced pancreatic cancer. To assess perioperative safety (including surgical morbidity and mortality within 60 days). To evaluate the safety and tolerability of immunotherapy in combination with chemotherapy for conversion therapy for unresectable locally advanced pancreatic cancer.

Primary Outcome MeasuresMeasure DescriptionTime Frame
Surgical Conversion RateThe surgery is scheduled to take place after a minimum of 4 weeks from the last dose to allow the effects of the drug to wear off. The eligible subjects can undergo surgery within 8 weeks from the last dose.8 weeks
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Pathologic response rate (pCR/MPR)pCR is defined as the proportion of subjects with complete disappearance of cancer cells from tumor lesions and lymph nodes. MPR is defined as the proportion of cancer cells in tumor lesions and lymph nodes < 10% of subjects, and the viable cells of carcinoma in situ are not included in the calculation of pCR. All tumor tissue and associated lymph node tissue samples should be grossly examined. Tissue samples should be sectioned at a thickness of 0.5 cm. Pathological evaluation should be performed for more extensive tumors with at least 1.0 cm thick sections.up to approximately 1 years
Objective response rate (ORR)ORR=(CR+PR)/ITT*100%, and the binomial distribution was used to calculate its 95%CI.up to approximately 1 years
Event-free survival (EFS)defined as the time from the start of treatment to the occurrence of any disease progression affecting surgery, postoperative disease progression or recurrence (per RECIST v1.1), or death due to any cause, whichever occurs first.up to approximately 1 years
Overall survival (OS)defined as the time from the first dose to death from any cause, whichever occurs first. Participants who were still alive at the last follow-up had OS as data censored at the time of the last follow-up. For participants lost to follow-up, OS was counted as data censored as the time to last confirmed survival before loss-to-follow.up to approximately 1 years

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

    Inclusion Criteria:
    1. Age 18-75 years old; 2. Histologically or cytologically confirmed pancreatic ductal adenocarcinoma (preferably histologically confirmed); 3. Judged by the investigator to be unresectable locally advanced (unresectable criteria refer to the guidelines for the diagnosis and treatment of pancreatic cancer); 4. Total bilirubin ≤ 2 mg/dL (subjects with bile duct stents can be enrolled if bilirubin ≤ 2 mg/dL and no cholangitis after stent placement); 5.
