Abstract

STUDY OBJECTIVE:

To investigate the efficacy and safety of a fully human monoclonal antibody recognizing the chemokine interleukin (IL)-8 in patients with COPD.

DESIGN:

Randomized, double-blind, parallel-group, placebo-controlled trial.

SETTING:

Eighteen clinics/hospitals in the United States.

PATIENTS:

One hundred nine patients with stable COPD.

INTERVENTIONS:

Three IV infusions of either monoclonal antibody recognizing IL-8 (800-mg loading dose; 400-mg subsequent doses) or active buffer solution administered monthly over a 3-month period.

MEASUREMENTS AND RESULTS:

The differences in the transition dyspnea index (TDI) total score, the primary outcome measure, between fully human monoclonal IgG(2) antibody directed against IL-8 and placebo were 0.8, 1.0, 0.8, and 0.3 at week 2 (p = 0.046) and months 1 to 3, respectively. At all time points, the proportion of patients achieving >/= 1 point improvement in the TDI was greater for the monoclonal antibody group compared with the placebo group: 28% vs 11% at week 2 (p = 0.028). There were no significant differences observed for lung function, health status, 6-min walking distance, and adverse events between groups.

CONCLUSIONS:

The results of this phase 2 study suggest that neutralization of IL-8 with monoclonal antibody therapy may improve dyspnea in patients with COPD. These results support the further investigation of monoclonal antibody therapy targeting IL-8 for the treatment of this disease.
