An Open-label, Phase I/II Study of PLENA Regimen in Patients With Unresectable Pancreatic Cancer or BTC
Study Details
Study Description
Brief Summary
Immunotherapy of cancer based on PD-1/PD-L1 blockade has prompted a revolution in cancer clinical management, albeit as yet immunotherapy-based treatment approaches in pancreatic cancer and biliary tract cancer (BTC) remain to have proven value, highlights the urgency for designing novel therapeutic strategies to combat these deadly diseases. The immunomodulatory effect of lenvatinib (Lenvatinib is an oral multi-kinase inhibitor) on tumor microenvironments may contribute to antitumor activity of immune checkpoint blockade. This one-arm, phase I/II study is designed to assess the safety and efficacy of the combined regimen of Durvalumab (anti-PD-L1 antibody), Lenvatinib and Paclitaxel albumin (nab-paclitaxel).

Outcome Measures
Primary Outcome Measures
- Number of Subjects with treatment-related adverse events (AEs) [6 months]
Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0. AEs were considered to be treatment-related if they had started or worsened within the interval from first study drug administration until the follow-up visit.
- Object response rate (ORR) [12 months]
ORR is defined as the proportion of subjects who achieved a partial response (PR) or complete response (CR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Secondary Outcome Measures
- Disease control rate (DCR) [12 months]
DCR is defined as the proportion of subjects who achieved a stable disease (SD), partial response (PR) or complete response (CR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
- Progression-free survival (PFS) [12 months]
PFS time was measured from study entry to the first documentation of disease progression or death. Disease progression was determined per the RECIST V1.1.
- Overall survival (OS) [24 months]
OS time was measured from the study entry to the date of death.
- Number of participants with laboratory test abnormalities [12 months]
The laboratory tests of serum cytokines and chemokines will be performed on day 1 of each cycle, and the abnormality will be determined by the investigator.
