Although the lung is accessible via inhalation, it functions to exchange air while keeping foreign bodies out, and very little drug stays in the lungs with commercial aerosols.
Delivering drugs to the lungs remains a challenge as very little drug gets to the lungs with IV and oral therapies, which are limited by blood dilution, hepatic metabolism, and GI absorption, and may have reduced efficacy due to dose limiting toxicity.
Aerosol technology is highly complex and barriers to entry have been high, limiting innovation. SOC technologies are older and less effective at drug delivery (carrier DPI, pMDI, nebulizers) and significant engineering challenges arise given the multiple realms of physics.
The pharmaceutical standard of care for lung cancer is primarily intravenous chemotherapy drugs, which have limited efficacy because of low drug concentration delivered to the lungs due to blood volume dilution.
Quench Medical’s inhalation technology delivers the drug directly to tumor tissues in the lung thereby enhancing its efficacy due to increased local drug concentration in the lung, and decreased systemic toxicity due to decreased systemic drug levels in the circulation.
Our new method delivers the chemotherapeutic drug via dry powder inhalation to reach lung tumors directly, in lower doses, in order to maximize the effectiveness and safety of the cancer treatment.
