Purpose:
This randomized phase-II trial (ClinicalTrials.gov identifier: NCT02767557) compared efficacy of gemcitabine/nab-paclitaxel (Gem/Nab) with or without the anti-interleukin-6 (IL-6) receptor antibody tocilizumab (Toc) for advanced pancreatic cancer (PC).
Methods:
A safety cohort received Gem 1,000 mg/m2 and Nab 125 mg/m2 on days 1, 8, and 15, and Toc 8 mg/kg on day 1 for each 28-day cycle. Participants with modified Glasgow prognostic scores of 1 or 2 were randomly assigned 1:1 to receive Gem/Nab/Toc or Gem/Nab. The primary end point was the overall survival (OS) rate at 6 months (OS6). Secondary end points were progression-free survival (PFS), overall response rate (ORR), and safety. Exploratory end points were cachexia, quality of life, and biomarkers, including the cachexia-promoting protein, growth differentiation factor 15 (GDF15).
Results:
Overall, 147 patients were treated, including six safety cohort participants. The median follow-up period was 8.1 months (IQR, 4.2-13.9). OS6 was 68.6% (95% CI, 56.3 to 78.1) for the Gem/Nab/Toc group and 62.0% (49.6-72.1) for the Gem/Nab group (P = .409). OS for Gem/Nab/Toc versus Gem/Nab improved at 18 months (27.1% v 7.0%, P = .001). No differences in median OS, PFS, or ORR were observed. Incidence of grade-3+ treatment-related adverse events (TrAEs) was 88.1% for Gem/Nab/Toc and 63.4% for Gem/Nab (P < .001). Gem/Nab/Toc decreased muscle loss versus Gem/Nab, with median change +0.1013% versus -3.430% (P = .0012) at 2 months and +0.7044 versus -3.353% (P = .036) at 4 months. Incidence of muscle loss was 43.48% on Gem/Nab/Toc versus 73.52% on Gem/Nab at 2 months (P = .0045) and 41.82% versus 68.75% (P = .0062) at 4 months. GDF15 was not changed by Gem/Nab or Gem/Nab/Toc.
Conclusion:
Although the primary end point was not met and TrAEs were increased by Toc, increased survival at 18 months and reduced muscle wasting support an anticachexia effect of IL-6 blockade independent of GDF15. Further studies could leverage these findings for precision anticachexia therapy.
