Extension Study (Extended Access) of Cyclosporine Inhalation Solution (CIS) in Lung Transplant and Hematopoietic Stem Cell Transplant Recipients for the Treatment of Bronchiolitis Obliterans

Bronchiolitis Obliterans (BO) is an obstructive lung disease that can affect individuals that have undergone a lung or hematopoietic stem cell transplant. BO has been studied most extensively in lung transplant recipients, where it is considered to represent chronic lung rejection. It is the leading cause of death after lung transplant, with mortality rates up to 55 percent. In hematopoietic stem cell transplantation, BO is thought to be a manifestation of chronic graft-vs-host disease (GVHD). Up to 45 percent of patients undergoing hematopoietic stem cell transplantation at the NHLBI develop a decline in pulmonary function. Conventional therapy for patients who develop BO consists of augmentation of systemic immunosuppressants. Systemic immunosuppression has limited efficacy for BO and is associated with deleterious consequences including increased risk of infections and decreased graft-versus tumor/leukemia effects.

Recently, cyclosporine inhalation solution (CIS) in solution with propylene glycol has been shown to improve overall survival and chronic rejection-free survival in lung transplant patients. These findings suggest targeted delivery of immunosuppressive therapy to the diseased organ warrants further investigation as this may minimize the morbidity associated with systemic immunosuppression. However, there currently exists limited data regarding the overall efficacy of inhaled cyclosporine to treat established BO following lung transplantation. Furthermore, inhaled cyclosporine has not been studied in the treatment of BO following hematopoietic stem cell transplantation.

Here, we propose to evaluate the long-term safety and efficacy, of inhaled CIS for the treatment of BO. Enrollment will be offered to subjects who have completed the end of study (week 18 visit) for the initial protocol (Phase II Trial of CIS in lung transplant and hematopoietic stem cell transplant recipients for treatment of Bronchiolitis Obliterans) and who have shown evidence of benefit (either an improvement or stabilization) in BO/BOS with CIS treatment.

Clinical parameters, including pulmonary function tests, will be measured in addition to laboratory markers of the anti-inflammatory response to CIS. Adverse events associated with extended treatment with CIS will be recorded.

The primary objective is to provide long-term safety and efficacy data for the use of CIS in hematopoietic transplant patients and lung transplant patients with established BO.

Secondary objectives include investigation of the inflammatory pathways that lead to chronic BO and ascertainment of the long term anti-inflammatory effects of this CSA preparation ex vivo and in vivo.

Primary endpoint is the efficacy of extended use CIS for BO/BOS. Secondary endpoints include the toxicity profile (adverse events), improvement in high resolution chest CT images, results of peripheral blood and bronchoalveolar cytokine arrays to assess secondary markers of inflammation, and functional capacity measurements using a six-minute walk test.

Description

• INCLUSION CRITERIA:

  1. Completed the End of Study visit (week 19) on the initial protocol (Phase II Trial of Cyclosporine Inhalation Solution (CIS) in Lung Transplant and Hematopoietic Stem Cell Transplant Recipients for Treatment of Bronchiolitis Obliterans) in the preceding 12 weeks
  2. Patients have shown evidence for a clinical benefit to CIS as evidenced by one or more of the following:
• Improvement in pulmonary function defined by a 10 percent or more increase in the FEV1 at week 18, confirmed with repeat PFTs at least 1 week apart.
• In patients with progressive disease at study entry on the initial protocol (Phase II Trial of Cyclosporine Inhalation Solution (CIS) in Lung Transplant and Hematopoietic Stem Cell Transplant Recipients for Treatment of Bronchiolitis Obliterans), stabilization in pulmonary function, defined as less than a 10 percent improvement in FEV1 or less than 10 percent decline in FEV1 at week 18, confirmed with repeat PFTs at least 1 week apart.
