Abstract

Introduction: The prognosis of patients with advanced biliary tract cancer (BTC) is still poor, and new strategies improving patients' outcome are needed. In our trial we investigated safety and activity of nab-paclitaxel in combination with gemcitabine and oxaliplatin as first-line systemic treatment for patients with advanced BTC.

Methods: In this investigator-initiated, multicenter, dose-escalation, single-arm phase I/II trial, patients were accrued into cohorts of 3 patients and dose escalation was performed following the standard 3 + 3 rule. Primary endpoint was the proportion of patients free from progression at 6 months. Secondary endpoints included safety and tolerability of the combination; progression-free survival (PFS); overall survival (OS); objective response rate (ORR); duration of response.

Results: Between July 2017 and December 2020, 67 patients were treated. Among the 10 patients in the phase I, no dose-limiting toxicity was observed, and dose level 2 was defined as recommended phase II dose for the phase II part. At data cutoff, the 6-month PFS rate was 49.1 % (95 % CI 40.8-57.5 %) with 28 patients out of 57 free from progression or death at 6 months. Median PFS was 6.3 months (95 % CI 3.6-10.1) and median OS was 12.4 months (95 % CI 8-23). ORR was 20.89 %. Most common grade 3 and grade 1-2 drug-related adverse events were neutropenia and peripheral neuropathy, respectively.

Conclusion: Triple chemotherapy demonstrated a favorable safety profile. However, the study did not meet its primary endpoint. Future studies will clarify the benefit of chemotherapy combinations in different settings. This trial is registered with ClinicalTrials.gov, NCT03943043.
