Brief Summary

This study aims to determine whether or not early spirometric detection and management of obstructive lung disease with combined fluticasone/azithromycin/montelukast therapy (FAM) can attenuate declining lung function, prevent the development of bronchiolitis obliterans, and improve patient outcomes following hematopoietic stem cell transplant.

Detailed Description

Bronchiolitis obliterans syndrome (BOS) is an inflammatory condition of the lungs that leads to obstructive physiology, irreversible fibrosis of terminal bronchioles, and obliteration of the small airways. In both children and adults, the prevalence of BOS is approximately 6% in those with chronic graft-vs-host disease (cGVHD), although this may be a gross underestimation given current diagnostic guidelines. Once diagnosed, the prognosis is extremely unfavorable. BOS carries a mortality rate of approximately 40-60%, with a five year survival rate of 13%.

Early on, BOS is symptomatically silent. Once symptoms are present, there is a high likelihood of irreversible disease regardless of the combination of immune suppression used. Given these circumstances, early diagnosis is of utmost importance, and can be characterized by an isolated and subclinical decline in lung function. Recent studies have suggested that early decline in lung function on pulmonary function testing (PFT) may be representative of developing BOS.

Due to the lack of consistent screening and diagnostic criteria, many patients with evolving BOS elude a timely diagnosis, thereby jeopardizing their chance of survival. In response, several experts have recommended frequent PFT screening and a modified, less stringent set of diagnostic criteria with the goal of establishing earlier diagnosis and timely intervention.

Traditionally, treatment of BOS has included aggressive immunosuppression, leaving patients at risk for life-threatening invasive infections, multi-system co-morbidities, and the threat of lung transplantation. Recent studies have demonstrated that early management with agents such as inhaled corticosteroids (ICS), macrolides, and leukotriene receptor antagonists (LTRA) can lead to improvements in both lung function and clinical symptoms.

This study aims to evaluate the utility of frequent and routine pulmonary surveillance in pediatric patients who have undergone allogenic HSCT. Our prospective study design provides a novel framework for the implementation of standardized lung function screening every three months in the first two years following HSCT. With this, we hypothesize that standardized PFT screening will improve diagnostic sensitivity and allow for earlier intervention in patients with evolving airway obstruction and BO.

This study also aims to evaluate the efficacy of inhaled fluticasone, azithromycin, and montelukast (FAM therapy) in the management of early airflow obstruction in pediatric patients following allogenic HSCT. Early airflow obstruction is defined by pulmonary function testing (FEV1 decline of ≥10% predicted with a FVC <0.8). With this, we hypothesize that FAM therapy will attenuate the progression of airflow obstruction and improve lung function in those with irreversible airflow obstruction at one and two years when compared to historical controls.

Informed consent must be signed prior to registration on study.

Exclusion Criteria

1. Subjects with a previous solid organ transplant.

2. Recurrent or progressive malignancy requiring anti-cancer therapy.

3. Subjects with evidence of underlying obstructive pulmonary disease prior to transplant (clinical history of asthma or baseline FEV1 <80% predicted with FEV1/FVC <80%).

4. Known history of allergy or intolerance to Montelukast, Zafirleukast, Azithromycin, Erythromycin, Clarithromycin, Prednisone, or Sirolimus.

5. Chronic supplemental oxygen requirement or hypoxemia <92% SpO2.

6. Clinical asthma (variable and recurrent symptoms of airflow obstruction and airway hyper-responsiveness).

7. Pregnancy or nursing: All females of childbearing age must have a negative serum or urine pregnancy test <7 days before study drug administration.

8. Chronic treatment with any inhaled steroid for >1 month in past three months.

9. Treatment with montelukast or zafirukast for >1 month in past three months.

10. Treatment with systemic steroids for >1 month in past three months.

11. Treatment with any FDA non-approved study medication within the past four weeks. Off label treatment with FDA approved medication is allowed.

12. Evidence of any viral, bacterial, or fungal infection involving the lung and not responding to appropriate treatment.

13. Inability to perform pulmonary function testing (PFT), as determined by the enrolling investigator or PFT lab.

14. Any condition that, in the opinion of the enrolling investigator, would interfere with the subject's ability to comply with the study requirements.
