In this HCPLive Special Report, experts review ensifentrine's role as a novel maintenance therapy for COPD.

In the opening segment of this HCPLive Special Report – RX Reviews, Antonio Anzueto, MD, professor of medicine and section chief of pulmonary at South Texas Veterans Healthcare System, provides a review of the clinical trial data supporting ensifentrine (Ohtuvayre) as a maintenance treatment for patients with chronic obstructive pulmonary disease (COPD).

The US Food and Drug Administration (FDA) approved Verona Pharma’s application for ensifentrine on June 26—moments after the recording of this segment—on the basis of Anzueto and colleagues’ findings from the phase 3 ENHANCE trials.1,2 The indication made ensifentrine the first COPD therapy with a novel mechanism of action approved by the FDA in more than a decade.

Here, Anzueto provides a detailed breakdown of the supporting clinical trial data for ensifentrine, as well as a review of its unique clinical benefit as an inhaled, nonsteroidal, dual inhibitor of the dual inhibitor of the phosphodiesterase 3 and 4 (PDE3; PDE4) pathways. Additionally, he and panel moderator David M. Mannino, MD, chief medical officer of the COPD Foundation and professor at the University of Kentucky, discuss the current state drug development in COPD, and what impact the FDA approval of ensifentrine may have on clinicians and their patients.
