Study summary

This is a prospective pilot study investigating exhaled breath condensate analyses to quantify the variability over time of various biomarkers associated with symptomatic pneumonitis.

Read the detailed description

Primary Objective:

  • To quantify the intra-person variability of concentrations of TGF-β1, IL-6, IL-1α, and IL-10 measured in exhaled breath condensate.

Secondary Objectives:

  • To examine the associations between differences in pre-treatment and post-treatment exhaled breath condensate concentrations of TGF-β1, IL-6, IL-1α, and IL-10 and the development of CTCAE grade 2+ symptomatic pneumonitis.
  • To examine the associations between serum measures of TGF-β1, IL-6, IL-1α, and IL-10 and:
  • Exhaled breath condensate measures of the same biomarkers, and
  • The development of CTCAE grade 2+ symptomatic pneumonitis.
  • To examine the association between microbiome signatures found in pre-treatment exhaled breath condensate and the development of CTCAE grade 2+ symptomatic pneumonitis.

What researchers measure

Primary outcomes

  1. Variability of Biomarkers

    Concentrations of TGF-β1, IL-6, IL-1α, and IL-10 (ng/mL) will be measured in exhaled breath condensate at baseline, at 2 weeks and after chemotherapy start and 6 weeks after chemotherapy start (the end of chemotherapy) and 1 month after completion of chemotherapy using a 2-tailed alpha of 0.05 with detectable standard deviation units from baseline to post treatment.

    Time frame: At baseline and one month after completion of chemotherapy

Secondary outcomes

  1. Differences in Concentrations of Biomarkers in Exhaled Breath Condensate From Baseline to 1 Month Post CRT

    TGF-β1, IL-6, IL-1α, and IL-10 (ng/mL) measured in exhaled breath condensate to compare mean change levels from (baseline), at 2 weeks after CRT start, 6-weeks after CRT start (the end of CRT), and 1 month after completion of chemotherapy using t-tests comparing mean change levels in each marker.

    Time frame: One month after completion of chemotherapy
