BRIDGEWATER, N.J., May 6, 2026 /PRNewswire/ -- Insmed Incorporated (Nasdaq: INSM), a people-first global biopharmaceutical company striving to deliver first- and best-in-class therapies to transform the lives of patients facing serious diseases, today announced a collaboration with Emmy^® Award–winning TV host, designer, and carpenter, Ty Pennington, to launch Suspect Bronchiectasis (Suspect BE). The educational initiative focuses on increasing awareness and proper diagnosis of bronchiectasis, a serious and chronic lung disease that may worsen over time and lead to lung damage. It encourages people with unresolved respiratory symptoms – such as cough, excess mucus, and recurrent lung infections, which may overlap with other respiratory conditions like chronic obstructive pulmonary disease (COPD) or asthma – to talk with a pulmonologist to see if additional testing, like a computed tomography (CT) scan, is the right next step to rule out or confirm bronchiectasis.

For the first time, Pennington is opening up to the public about his experience as a caregiver to his mother who has lived with bronchiectasis for nearly two decades. Her journey living with unresolved respiratory symptoms for more than 40 years, along with the extended time it took for her to receive a bronchiectasis diagnosis, motivated Pennington to team up with Insmed to help raise awareness about the disease. As part of the initiative, Pennington draws on his home improvement expertise to highlight an important parallel: whether in a home or the lungs, taking a deeper look means exploring beyond the surface and suspecting when more could be going on.

"When I begin a renovation, I start by scanning the home – the foundation, the walls, and the attic – because looking deeper can give you a full picture. I believe the same is true with your health – taking a closer look could help with getting the answers you need," Pennington shares. "Watching my mom cope with breathing challenges, hospital visits, and the uncertainty of not always knowing what was going on had a big impact on our family. Through Suspect BE, I hope to encourage people to have deeper conversations with their healthcare providers and suspect bronchiectasis."

Bronchiectasis is a chronic lung disease where the airways become widened and damaged, making it harder for the lungs to clear mucus and bacteria. Approximately 500,000 people in the U.S. are diagnosed with bronchiectasis, but millions more people may be living with the disease without knowing it. Increasing awareness of bronchiectasis may help people better understand what could be behind their symptoms and know when it may be appropriate to have a healthcare professional take a deeper look.

"At Insmed, our hearts are with the people navigating life with serious health conditions. We believe that when patients have the right information, they feel more confident asking questions and having real, honest conversations with their doctors," said Martina Flammer, M.D., MBA, Chief Medical Officer of Insmed. "Because bronchiectasis symptoms, like a chronic cough, recurring infections, or excess mucus, can look a lot like other lung conditions, it often takes years to get the right diagnosis, reinforcing the need for greater awareness and earlier identification, which Suspect BE is designed to help address."
