VESTIGE: The first randomized trial to use FRI and other methods to assess the effect of DUPIXENT on FeNO, lung function, airway volume, and mucus burden

The primary imaging endpoint ([s]iVaw at TLC) did not reach statistical significance (P>0.05); therefore all subsequent endpoints are descriptive; definitive conclusions cannot be made.1

FeNO
57%

of patients were observed
to achieve FeNO <25 ppb
with DUPIXENT 300 mg Q2W + SOC
(n=72) vs 11% of placebo + SOC patients
(n=37) at Week 24 (primary endpoint)1

Airway volume
20%

increase in airway volume observed ([s]iVaw at TLC) from baseline with
DUPIXENT 300 mg Q2W + SOC (n=72) vs
2% decrease with placebo + SOC (n=37)
at Week 24 (second primary endpoint)1,a

FEV1
660mL

increase in pre-bronchodilator
FEV1 observed
with DUPIXENT 300 mg Q2W + SOC (n=72)
vs 270 mL with placebo + SOC (n=37) at
Week 24 (secondary endpoint)1,2,a

Mucus score
3.5

decrease in mucus plug score observed with DUPIXENT 300 mg Q2W + SOC (n=72) vs
1.4 increase with placebo + SOC (n=37) (LSM
difference [SE] vs placebo: –4.9 [0.8]) at
Week 24 (secondary endpoint)1,3,a,b

Mucus plugs
67%

of patients were observed to reduce or eliminate mucus plugging with DUPIXENT 300 mg Q2W + SOC (n=72) vs
a reduction in 23% of placebo + SOC patients
(n=37) at Week 24 (exploratory endpoint)1,2,a,c


aResults are descriptive. Definitive conclusions cannot be made. Please see study design for full limitations.

bThe mucus plug score was calculated as the number of bronchopulmonary segments that contained at least one mucus plug. Range was 0-18, with higher values indicating a greater mucus plug burden.1

cAt Week 24, 14.8% of DUPIXENT patients eliminated mucus plugs and 52.5% had a reduced mucus score (>0-3.5) vs 0% of placebo patients with a mucus score of 0 and 23.3% of placebo patients who had a reduced mucus score (>0-3.5).2

Decrease in mucus score with DUPIXENT was correlated with changes in pre‑
bronchodilator FEV11,d

dPearson’s correlation coefficient for mucus score/pre-bronchodilator FEV1: r[60]=−0.62.1

IL-13 signaling mediates local inflammation, impacting FeNO levels, mucus hypersecretion, and airway obstruction4,5

FeNO is a type 2 inflammation biomarker associated with exacerbation risk and lung function decline6,7

  • 50% increase in exacerbation risk in patients with FeNO >50 ppb6
  • 2.7 times increased risk of rapid lung function decline in patients with FeNO >40 ppb7

ONLY DUPIXENT DIRECTLY INHIBITS IL-4 AND IL-13 SIGNALING8,*

*The mechanism of dupilumab action has not been definitively established.

FeNO <25 ppb observed in 57% of DUPIXENT patients vs 11% with placebo at Week 241
Percentage of patients achieving FeNO <25 ppb (primary endpoint, Week 24)
Increase in pre-bronchodilator FEV1 by 600 mL observed with
DUPIXENT vs 270 mL with placebo at Week 241,2
Change from baseline in pre-bronchodilator FEV1 (secondary endpoint, Week 24)1,2

Results are descriptive. Definitive conclusions cannot be made.

Reductions in FeNO levels and increases in airway volumes were correlated with changes in lung function1,e,f

ePearson’s correlation coefficient for FeNO/pre-bronchodilator FEV1: r[68]=−0.40.1

fPearson’s correlation coefficient for (s)iVaw [%]/pre-bronchodilator FEV1: r[60]=0.23.1

Decrease in mucus plug score of 3.5 observed with DUPIXENT vs 1.4 increase with placebo at Week 241,g
Change in mucus plug score
(secondary endpoint, Week 24)1,b,g

Mucus plugs are defined as complete occlusions of the airway visible at TLC.

Results are descriptive. Definitive conclusions cannot be made. Change from baseline in global mucus score at Week 4 was an exploratory endpoint. Please see study design for full limitations.

gWith DUPIXENT 300 mg Q2W + SOC (n=72) vs placebo + SOC (n=37) (LSM difference [SE] vs placebo: −4.9 [0.8]).3

Elimination or reduction of mucus plugs observed in 67% of DUPIXENT patients vs a reduction in 23% of placebo patients at Week 242,c
CT scans of change in mucus plug volume (VESTIGE, exploratory endpoint, Week 24)1

CT scans correspond to patients with changes in mucus plug volume that matched the mean percentage changes observed in the ITT population.
Results are descriptive. Definitive conclusions cannot be made.
