A Proposal to Test the Efficacy and Tolerability of Bortezomib in Pulmonary Chronic GVHD
Bronchiolitis ObliteransApproximately 10,000 allogeneic hematopoietic stem cell transplants (HSCT) are performed annually in the US for various indications. Bronchiolitis obliterans (BO) is the most common late noninfectious complication following allogeneic hematopoietic stem cell transplant. Prognosis of BO in the allogeneic HSCT setting is dismal and there are no therapies proven to be consistently effective. The exact incidence is not clear but may be as high as 30%2 . Risk factors include new or ongoing chronic graft versus host disease (cGVHD), age, antecedent obstructive airways disease and viral infections1. BO is characterized physiologically by progressive irreversible airflow obstruction and pathologically by luminal occlusion of the distal airways due to progressive scarring3. The pathogenesis is not completely understood but the cytokine transforming growth factor-beta 1 (TGF-b1), important for both tissue repair and fibrosis, is thought to play a pivotal role. Bortezomib, an FDA approved proteasomal inhibitor inhibits TGF-b1 signaling in vitro and protects against lung injury/fibrosis in bleomycin mouse model as well as in a mouse model for skin fibrosis. This is consistent with other data in the literature that proteasomal inhibition can prevent the development of fibrosis. Thus the investigators propose to test the safety, tolerability and efficacy of bortezomib in chronic pulmonary GVHD (BO).
Safety Study of Aztreonam Lysine for Inhalation (AZLI) in the Treatment of Early Bronchiolitis Obliterans...
Complication of Transplanted LungThis study is a pilot two- center study to determine if aztreonam lysine for inhalation AZLI can be safely and self-administered in lung transplant recipients with newly diagnosed bronchiolitis obliterans syndrome, grade 1 (BOS) and obtain pilot data regarding its effect on lung function in order to appropriately design and power a larger multicenter randomized study. The hypothesis is that AZLI is a safe and effective treatment for declining lung function in lung transplant recipients with early stage BOS.
A Study to Evaluate the Potential of Mesenchymal Stromal Cells to Treat Obliterative Bronchiolitis...
Bronchiolitis ObliteransLung TransplantationThe primary aim of this study is to establish the safety of infusions of Mesenchymal Stromal Cells (MSC) from related or unrelated Human Leukocyte Antigen (HLA) identical or HLA mismatched donors in the management of bronchiolitis obliterans syndrome after lung transplantation.
European Trial of Pirfenidone in BOS, A European Multi-center Study
Disorder Related to Lung TransplantationCLAD1 moreA European multi-centre, randomised, double-blind placebo-controlled trial of Pirfenidone in bronchiolitis-obliterans-syndrome grade 1-3 in lung transplant recipients. Randomized double blinded, placebo controlled study. Eligible patients are to be randomized in a 1:1 ratio to receive either Pirfenidone 2403 mg/d or the matching placebo treatment for 6 months. Primary objective To evaluate the effect of Pirfenidone on the change in FEV1 in liters over 6 months in lung transplant recipients with bronchiolitis obliterans syndrome.
Prospective Evaluation of the Efficacy of Budesonide/Formoterol in Bronchiolitis Obliterans in AHSCT...
Obstructive Airway DiseaseThe usual treatment for obstructive airway disease (OAD) after allogeneic hematopoietic stem cell transplantation (AHSCT) , which is related to graft versus host disease (GVHD), consists of intensification of systemic immunosuppressive therapy.

Bronchiolitis ObliteransAcute Obliterating BronchiolitisWe looked for the effectiveness of low-dose long-term prescription of erythromycin in mustard-induced bronchiolitis obliterans
Study of Enbrel (Etanercept) for the Treatment Sub-Acute Pulmonary Dysfunction After Allogeneic...
Lung InjuryAcute3 moreThe purpose of this study is to determine the effectiveness of etanercept in the treatment of patients with sub-acute lung injury following a bone marrow transplant. This study will also examine the toxicity of treatment with etanercept as well as whether there is an improved quality of life in these patients.
Prospective Study for Transplant Optimization Using Functional Imaging (TROFI)
Bronchiolitis ObliteransLung Transplant RejectionThe objective of this study is to detect BOS in an early stage by using the outcome parameters generated by Functional Respiratory Imaging (FRI). Robust and automated segmentation algorithms will be developed for these parameters, focusing on quantitative computed tomography (CT) image analyses to provide the physician a more sensitive diagnostics tool. The evolution of rejection over time will be monitored using non-rigid image registration methods.
The Safety and Tolerability of Pirfenidone for BOS After HCT
Bronchiolitis ObliteransGraft Vs Host DiseaseThis is a phase 1, non-randomized, single-arm, open label, single center clinical trial to determine the tolerability and safety of pirfenidone in patients with BOS associated with lung GVHD after hematopoietic cell transplant.
L-CsA in the Prevention of Bronchiolitis Obliterans Syndrome (BOS) in Lung Transplant (LT) Patients...
Bronchiolitis ObliteransImmunosuppression is a key intervention in patients with solid organ transplant and is usually achieved by combination therapy with systemic CsA or tacrolimus with azathioprine, mycophenolate mofetil (MMF), or corticoids. However, the outcomes after lung transplantation are poor when compared with those after heart, kidney, or liver transplantation, with a survival rate of only 55% for recipients of lung transplants. Additional application of aerosolised L-CsA should suppress T-cell activation in the lung tissue and subsequently BOS development. The overall purpose of this phase-II/III study is to obtain efficacy and safety data of L-CsA in the prevention of BOS.
