Clinical Trial: Targeted Therapy of Bronchiolitis Obliterans Syndrome

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Fluticasone Propionate, Azithromycin, and Montelukast Sodium in Treating Patients With Bronchiolitis Obliterans Who Previously Underwent Stem Cell Transplant

Brief Summary: This phase II trial studies how well giving fluticasone propionate, azithromycin, and montelukast sodium (FAM) together works in treating patients with bronchiolitis obliterans who previously underwent stem cell transplant. FAM may be an effective treatment for bronchiolitis obliterans

Detailed Summary:

PRIMARY OBJECTIVES:

I. To determine if the combination treatment of FAM administered in post hematopoietic cell transplantation (HCT) recipients after the diagnosis of new onset bronchiolitis obliterans syndrome (BOS) can decrease the rate of treatment failure relative to an estimated historical rate of 40% using current therapies.

SECONDARY OBJECTIVES:

I. To confirm the safety profile of FAM.

II. To describe the effect on other standard pulmonary function test parameters: forced expiratory flow at 25%-75% of forced vital capacity (FVC) (FEF25-75), residual volume (RV), diffusion capacity of carbon monoxide (DLCO), forced expiratory volume in 1 second (FEV1)/FVC ratio and FEV1/slow vital capacity (SVC) ratio with FAM treatment.

III. To determine the change in molecular markers of inflammation and fibrosis in the blood with FAM treatment.

IV. To assess the impact of FAM on other chronic graft-versus-host disease (GVHD) manifestations.

V. To assess the impact of FAM on functional status, and health-related quality of life (HRQOL).

VI. To describe changes in steroid dosing.

OUTLINE:

Patients receive fluticasone propionate inhaled orally (PO) twice daily (BID), azithromycin PO 3 days a week, and montelukast sodium PO once daily (QD). Treatment continues for 6 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followe

Current Primary Outcome: Treatment failure [ Time Frame: Within 3 months after initiation of study medications ]

Must be confirmed by a second PFT 2 weeks after the first measurement. A sustained, absolute decrease (worsening) of the FEV1 by >= 10% predicted in comparison to the baseline FEV1.


Original Primary Outcome: Treatment failure [ Time Frame: Within 3 months after initiation of study medications and confirmed by a second PFT 2 weeks after the first measurement ]

A sustained, absolute decrease (worsening) of the FEV1 by >= 10% predicted in comparison to the baseline FEV1


Current Secondary Outcome:

  • Incidence and types of National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) (v4.0) [ Time Frame: Up to 6 months ]
    Grade 3-5 serious adverse events (SAEs) attributable to FAM; and the proportion of subjects who stop each drug during the study period.
  • Changes in FEF 25-75, RV, DLCO, FEV1/FVC ratio and FEV1/SVC ratio [ Time Frame: Baseline to 6 months ]
    Will include FEV1 at month 6.
  • Changes in blood molecular markers: IL8 (azithromycin), cysteinyl and LTB4 (monteleukast), and IL1B, TNF, and IL6, as well as neutrophil count (fluticasone) [ Time Frame: Baseline to 6 months ]
  • Using the National Institute of Health (NIH) consensus criteria, the proportion of subjects with improvements in other chronic GVHD characteristics [ Time Frame: Up to 6 months ]
    Because of the relatively small sample sizes, results will be reported descriptively with 95% confidence intervals.
  • Changes in HRQOL, exercise capacity, and symptoms compared to baseline [ Time Frame: Baseline to 6 months ]
    Using the following measurements: Short Form (SF) 36, Functional Assessment of Cancer Therapy (FACT), Human Activity Profile (HAP), chronic GVHD symptom scale for participants >= 18 years of age; Activity Scale for Kids (ASK) for participants < 18 years of age; six minute walk test.
  • Total systemic steroid exposure [ Time Frame: Up to 6 months ]


Original Secondary Outcome:

  • Incidence and types of National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) (v3.0) [ Time Frame: At months 1, 2, 3, and 6 ]
  • Changes in FEF 25-75, RV, DLCO, FEV1/FVC ratio and FEV1/SVC ratio [ Time Frame: At months 3 and 6 (including FEV1 at month 6) ]
  • Changes in blood molecular markers: IL8 (azithromycin), cysteinyl and LTB4 (monteleukast), and IL1B, TNF, and IL6, as well as neutrophil count (fluticasone) [ Time Frame: At month 3 and month 6 ]
  • Using the National Institute of Health (NIH) consensus criteria, the proportion of subjects with improvements in other chronic GVHD characteristics [ Time Frame: At month 3 and month 6 ]
  • Changes in HRQOL, exercise capacity, and symptoms compared to baseline [ Time Frame: At month 3 and month 6 ]
  • Total systemic steroid exposure [ Time Frame: By month 3 and month 6 ]
