Bronchiolitis Obliterans Syndrome Understanding

Bronchiolitis Obliterans Syndrome: Overview

Bronchiolitis obliterans syndrome is a form of chronic lung allograft dysfunction that affects the majority of lung transplant recipients. It is the principal factor limiting long-term transplant survival. BOS is characterized by progressive airflow obstruction unexplained by acute rejection, infection, or other coexistent condition. Although BOS is a proven useful clinical syndrome that identifies patients at increased risk for death, its clinical course and underlying causative factors are now recognized to be increasingly heterogeneous.


Symptoms generally progress slowly over weeks to months. Common symptoms include:

  • Shortness of breath and/or wheezing
  • Decreased exercise or activity tolerance and endurance
  • Fatigue
  • Dry Cough


Bronchiolitis obliterans may result from lung injury caused by a variety of different chemicals and respiratory infections. Inhaled chemicals known to irritate the lungs and lead to the condition include chlorine; ammonia; oxides of nitrogen or sulfur dioxide; welding fumes; or food flavoring fumes (such as diacetyl). Respiratory infections caused by a respiratory syncytial virus, adenovirus, or Mycoplasma pneumonia have been linked with the condition.  


A better understanding of BOS pathogenesis is important if rational strategies are to be developed for its management.The histopathological features of BO suggest that injury and inflammation of epithelial cells and subepithelial structures of small airways lead to excessive fibro-proliferation due to ineffective epithelial regeneration and aberrant tissue repair. To support the basis for the pathogenesis of BOS two hypotheses have been proposed by several studies to explain the pathogenesis of chronic rejection which is alloimmune and nonalloimmune mechanisms.


Bronchiolitis Obliterans Syndrome (BOS) remains the major problem which ceases long-term survival after lung transplantation. Treatment and prevention of BOS are quite challenging. Currently, there is no approved or standard treatment for BOS and successful treatment is defined as stabilization or reduction in the rate of FEV1 decline. An important focus of treatment of BOS patients is optimizing immunosuppression to prevent further lung allograft rejection. Current treatment consists primarily of augmenting immunosuppression by changing medications within therapeutic classes, by adding medications, or by applying non-medicinal immuno-modulating therapies. An increasing number of induction and maintenance immunosuppressive agents have become available over time for use in various combinations allowing for more choice and personalization of immunosuppressive therapy.Despite several advancements, there are pros and cons to each immunosuppressive agent and a regimen that leads to prolonged survival yet is void of associated morbidity including infection, malignancy, and drug-related toxicities, etc. are still under regress research and development.

Bronchiolitis Obliterans Syndrome Emerging Drugs Chapters

This segment of the Bronchiolitis Obliterans Syndrome report encloses its detailed analysis of various drugs in different stages of clinical development, including phase III, II, I and preclinical. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Bronchiolitis Obliterans Syndrome Emerging Drugs

  • Liposomal Cyclosporine A: Breath Therapeutics (a Zambon Company)

Breath Therapeutics a Zambon Group Company (a spin-off of PARI Pharma) is developing Liposomal Cyclosporine A for Inhalation (L-CsA-I; also known as Ciclosporin inhalation and Cyclosporine A Inhalation) as the first potential therapy for Bronchiolitis Obliterans Syndrome (BOS). It is the lead drug candidate and is a proprietary liposomal formulation of cyclosporine A for inhalation administered via a drug-specific investigational PARI Pharma’s eFlow nebulizer, being designed for inhaled delivery to the lungs.

  • Pirfenidone: Genentech 

Genentech is developing Pirfenidone, a pyridone small molecule, orally active, an antifibrotic agent that inhibits the synthesis of TGF-beta, a chemical mediator that controls many cell functions, including proliferation and differentiation, and plays a key role in fibrosis. Pirfenidone also inhibits the synthesis of TNF-alpha, a cytokine that is known to have an active role in inflammation. 

  • Ruxolitinib: Incyte Corporation

Ruxolitinib (also known as INC-424; INCB 018424 phosphate; INCB-018424; INCB-18424; Jakafi; Jakavi and ruxolitinib phosphate) is a small molecule, first-in-class Janus kinase 1 (JAK1)/JAK2 inhibitor. It is developed and marketed by Incyte Corporation, indicated for the treatment of patients with intermediate or high-risk Myelofibrosis and for patients with Polycythemia Vera with inadequate response or intolerance of hydroxyurea.

The drug is approved by the brand name JAKafi in the United States and JAKavi by Novartis outside United States.

Report Highlights

  • The companies and academics are working to assess challenges and seek opportunities that could influence Bronchiolitis Obliterans Syndrome R&D. The therapies under development are focused on novel approaches to treat/improve Bronchiolitis Obliterans Syndrome.
  • In January 2020, Altavant Sciences acquired Onspira Therapeutics. The Company is intended to develop OSP-101 for the treatment of Bronchiolitis Obliterans Syndrome, the leading cause of morbidity and mortality in post-lung transplant patients.
  • In May 2017, PARI Pharma gained Orphan Drug Designation for L CsA i for the treatment of BOS by the European Commission. L-CsA-i has also received Orphan Drug Designation from the FDA for the treatment of bronchiolitis obliterans.
  • Breath Therapeutics’ drug device platform consists of liposomal drug-aerosol formulations and cutting-edge inhalation technology. The basis for successful inhalation therapy is precise and fast drug delivery into the small airway of the lungs. This requires a uniquely designed drug formulation paired with a high-performance, drug-specific nebulizer.
  • In August 2014, Roche and InterMune reach a definitive merger agreement in which Roche acquired InterMune for USD 74.00 per share. This corresponds to a total transaction value of US$ 8.3 billion on a fully diluted basis.
