Holaira is working on a catheter-based system for a procedure called targeted lung denervation, which has the potential to make breathing easier for patients with chronic obstructive pulmonary disease (COPD).
Vertex venture partner Lincoln Chee said, “Until now, COPD patients have had few options for managing their symptoms.
“We believe that Holaira’s proprietary technology enables a fundamental advance in COPD treatment.
“We anticipate that this simple bronchoscopic treatment will provide lasting lung function improvement by opening obstructed airways.”
