Circassia’s marketed and pipeline products target asthma and chronic obstructive pulmonary disease (COPD), and offer significant commercial potential.
NIOX® asthma management
Asthma represents one of the largest healthcare burdens. In the US alone, there are 25 million asthmatics, with the economic cost of asthma estimated to account for over $80 billion per year. Worldwide, asthma affects 235 million people and is the most frequent chronic disease among children. As a result, our marketed NIOX® products have a major commercial opportunity, and estimates suggest the potential specialist market in the US alone approaches $200 million per year.
Flixotide® / Flovent® substitute
Circassia’s product targets substitution of GSK’s Flixotide®/Flovent® pMDI, which generated global sales of $775 million in 2017 in pMDI and DPI formats. Due to the formulation challenges associated with inhaled respiratory medicines, and relatively limited competition in the pMDI market segment, our particle-engineered products have a significant potential commercial opportunity.
Seretide® substitute market
Our product contains fluticasone propionate and salmeterol xinafoate. These are the active components in GSK’s Seretide® combination therapy, which generated European sales of over $950 million in pMDI / DPI in 2017. The complexity of producing a directly substitutable version of Seretide® using traditional manufacturing technology, the rigorous standards required for approval and the limited competition in the pMDI market segment present a major potential opportunity for Circassia’s product.
COPD is a major health burden. The World Health Organization estimates that approximately 65 million people worldwide have moderate-to-severe COPD and it is predicted to become the third leading cause of death by 2030.
Circassia promotes the COPD treatment Tudorza® (aclidinium bromide) in the United States as part of its collaboration with AstraZeneca. The product is part of the long-acting muscarinic antagonist containing market, which totalled approximately $2.6 billion in 2017, and third-party estimates suggest that Tudorza® has the potential to achieve peak sales of over $90 million in the United States.
Circassia holds the US commercial rights to Duaklir®*, a fixed dose combination of aclidinium bromide and formoterol fumarate. The product was recently filed for approval in the US market and is approved in approximately 50 other countries including the EU. Third-party research suggests Duaklir® has a peak sales opportunity of over $180 million in the United States.
*The Duaklir® trademark is registered in the United States; the mark is not currently approved for use by the FDA.
Circassia’s product contains tiotropium bromide, the active component in Boehringer Ingelheim’s dry powder treatment Spiriva® Handihaler®. Spiriva® is also available as an inhalation spray and is approved in a number of countries, including the US. The product accounted for total revenues of $3.2 billion in 2017.
Novel LABA / LAMA formulation & novel COPD therapy formulation
Circassia’s two novel formulations of currently approved drugs target an underserved segment of the specialist moderate-to-severe COPD market.
- The first contains a LABA / LAMA fixed dose combination. Third-party research suggests the product targets a patient population of up to 350,000 in the US and EU5 with a potential peak sales opportunity of up to $700 million.
- The second targets reductions in COPD exacerbations. The US / EU5 target patient population totals up to 200,000 and market research indicates the product has a potential peak sales opportunity of up to $250 million.
