Commercial opportunity

Circassia’s portfolio of products target use in various respiratory indications, including 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 used in asthma diagnosis and management have a major commercial opportunity.

COPD treatments

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, where it has the commercial rights to the product. Tudorza® is part of the long-acting muscarinic antagonist (LAMA) market, which totalled approximately $2 billion in revenues in the US in 2018 with Tudorza® accounting for approximately 2.6% of prescriptions. As a result, Tudorza® has significant potential, with a modest improvement in market share and / or a move to higher value channels representing a growth opportunity.


Circassia holds the US commercial rights to Duaklir®, a fixed dose combination of aclidinium bromide and formoterol fumarate. The product was launched in the US in October 2019 targeting the US LAMA /LABA market, which is predicted to grow rapidly from an estimated $1 billion in 2019 to over $1.5 billion in the coming five years.

LungFit PH nitric oxide product

Inhaled nitric oxide is a pulmonary vasodilator, which is approved in the United States for use as part of a regimen in the treatment of hypoxic respiratory failure associated with persistent pulmonary hypertension of the newborn. The currently available product, INOMAX®, is used in neonatal intensive care units (NICUS) and its delivery system administers nitric oxide from pressurized cylinders in conjunction with ventilator systems. The product generated estimated US revenues of over $400 million in 2018.

LungFit PH* is a portable system that utilizes an electric voltage to produce precise quantities of nitric oxide from the nitrogen and oxygen in air. It offers a number of potential benefits over the existing competition. It is cylinder-free and is smaller, significantly lighter and more convenient and, unlike nitric oxide cylinder-based systems, does not require special storage and handling. As a result, it has the potential for use by NICUs, as well as smaller clinics without the facilities required to manage nitric oxide cylinders.

*LungFit PH is not an approved name for the product and may not be the final name submitted for approval
