Two decades after the identification of the cystic fibrosis transmembrane conductance regulator protein, approved drugs capable of correcting dysfunctions in this protein are nearing reality. This report captures the thoughts of cystic fibrosis specialists on this exciting development, and also highlights potentially life-extending innovations among inhaled antibiotics.
Features and benefits
- Features a multi-parameter assessment of the cystic fibrosis pipeline from preclinical to preregistration.
- Identifies the most promising innovative new candidates within the pipeline.
- Analyzes the changes to the cystic fibrosis research portfolio over the past 2.5 years.
- Discusses the key learnings from candidates recently discontinued from late-stage cystic fibrosis clinical trials.
- In-depth interviews with four key opinion leaders reveal strong views on unmet needs and target product profiles.
- There remain significant unmet needs among cystic fibrosis (CF) patients, but commitment to the discovery of new therapies is growing. The pharmaceutical industry and CF organizations have increased their efforts significantly. Over the past 2.5 years the CF pipeline has grown by 11%, and the number of clinical trials active/recruiting has doubled.
- Key opinion leaders interviewed by Datamonitor were unanimous in their praise for the great strides made by protein repair treatments. Courtesy of work done by Cystic Fibrosis Foundation Therapeutics, PTC Therapeutics and Vertex, there is now precedent for small molecule-mediated protein repair across the most common three classes of CF mutation.
- An arms race is emerging between increasingly resilient lung bacterial infections and the next generation of inhaled antibiotics. CF specialists are looking to powerful broad-spectrum agents and/or biofilm-penetrating liposomal formulations to counter the threat posed by the rising incidence of aminoglycoside-resistant pathogens.

Datamonitor key findings
CLINICAL PIPELINE OVERVIEW
Despite increased life expectancy there remains an urgent need for improved cystic fibrosis treatments
Pipeline is growing but is still dominated by early-stage candidates
Scant options currently exist for treating cystic fibrosis
Full pipeline demonstrates high project turnover and mechanistic diversity
Few companies have more than one cystic fibrosis therapy in their portfolio
Cystic fibrosis research is narrowing its focus onto preferred therapeutic classes
More emphasis is on symptomatic therapies
Protein repair treatment leads the way among the disease-modifying approaches
Late-stage candidates promise wider treatment options in the near future
TOBI Podhaler (tobramycin inhalation powder; Novartis)
Bronchitol (mannitol; Pharmaxis)
Colobreathe (colistin; Forest Laboratories)
Kalydeco (ivacaftor, VX-770; Vertex/CFFT)
Solpura (Trizytek, liprotamase; Eli Lilly/CFFT)
Aeroquin (levofloxacin, MP-376; Aptalis Pharma/PARI)
