CHF 4226 pMDI

Chiesi Farmaceutici S.p.A. · Phase 2 active Small molecule Under review Quality 0/100

CHF 4226 pMDI is a LABA/LAMA combination bronchodilator Small molecule drug developed by Chiesi Farmaceutici S.p.A.. It is currently in Phase 2 development for Chronic obstructive pulmonary disease (COPD) maintenance treatment. Also known as: Carmoterol HFA.

CHF 4226 is an inhaled dual bronchodilator combining a long-acting beta-2 agonist and long-acting muscarinic antagonist for maintenance treatment of chronic obstructive pulmonary disease.

CHF 4226 pMDI is a small molecule beta-2 adrenergic receptor agonist used to treat Chronic Obstructive Pulmonary Disease. It is administered via a pressurized metered-dose inhaler (pMDI) and has been studied in clinical trials for its effects on the QTc interval in healthy volunteers.

If approved by FDA: likely 2031–2034
Steps remaining: Phase 3 → NDA/BLA submission
Confidence: Medium
Why this estimate
  • Baseline phase 2 → approval rate +15.3pp
    Industry-wide phase 2 drugs reach approval ~15.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2031–2034
EMA EU 2032–2035 +0.7 yr
MHRA GB 2032–2035 +0.7 yr

Mechanism of action

The drug delivers two complementary bronchodilators via pressurized metered-dose inhaler (pMDI): a LABA component that activates beta-2 adrenergic receptors to increase cAMP and relax airway smooth muscle, and a LAMA component that blocks M3 muscarinic receptors to prevent acetylcholine-induced bronchoconstriction. This dual mechanism provides sustained airway dilation and improved lung function in COPD patients.
