ClinicaliQ Trial Snapshot
  • A Study to Compare Safety of 4 Weeks Exposure to Propellants Hydrofluoroalkane 1,1-difluoroethane (HFA-152a) and HFA-1,1,1,2-tetrafluoroethane (134a) — Recruiting • Phase III • Respiratory / COPD / Asthma • NCT07645248.
  • What is being tested: Safety comparison of two propellant formulations in metered dose inhalers (MDIs) over 4 weeks exposure—HFA-152a (test propellant) versus HFA-134a (established reference propellant)—to generate additional safety data on the propellant component of reformulated inhaled products.
  • Patient eligibility overview: Study participants include patients requiring regular inhaled medication via MDI who can tolerate 4 weeks of controlled propellant exposure; specific inclusion/exclusion criteria would typically assess baseline respiratory function, stability of condition, and ability to comply with study protocol requirements.

What This Trial Is Studying

This study aims to generate additional safety data on the propellant component of the reformulated product by comparing metered dose inhaler (MDIs) containing HFA-152a (test) with HFA-134a (reference).
