WEST LAFAYETTE, Ind.<\/strong> \u2014 Qi \u201cTony\u201d Zhou, a researcher in Purdue University\u2019s\u00a0College of Pharmacy<\/a>\u00a0has received a $2.4 million grant from the National Institutes of Health to fight lung infections that have established a resistance to antimicrobial drugs.<\/p>\n\n\n\n

Zhou is an associate professor in the Department of Industrial and Molecular Pharmaceutics<\/a>, a Faculty Scholar and a faculty member of the Purdue Institute for Drug Discovery<\/a> and the Purdue Institute of Inflammation, Immunology and Infectious Disease<\/a>. He leads a team of multinational experts from Australia, Thailand and the United States in developing novel, patent-pending inhalation therapeutics for lung infections.<\/p>\n\n\n\n

\u201cWe are providing a promising option to fight the global crisis of antimicrobial resistance,\u201d Zhou said. \u201cThe successful development of our invention could save tens of thousands of lives from a variety of deadly lung infections, including cystic fibrosis and ventilator-assisted pneumonia.\u201d<\/p>\n\n\n\n

Zhou\u2019s research in antimicrobial resistance has yielded two U.S. patents, four patent applications and more than 70 publications in peer-reviewed journals. The most recent peer-reviewed journal publications were in Pharmaceutics<\/a> in March 2024 and Pharmaceutical Research<\/a> in August 2022.<\/p>\n\n\n\n

With the latest NIH grant, Zhou has now received six federal grants totaling $10 million, including three NIH R01 grants in the past eight years to support the inhalation therapeutics research. <\/p>\n\n\n\n

The threat of antimicrobial resistance<\/strong><\/h2>\n\n\n\n

Thomas Sors, director of scientific strategy and relations at the Purdue Institute of Inflammation, Immunology and Infectious Disease, said antimicrobial resistance represents a severe global health threat as pathogens increasingly evade traditional treatments.<\/p>\n\n\n\n

\u201cThe Centers for Disease Control and Prevention note that each year in the U.S., drug-resistant infections affect over 2.8 million individuals and result in more than 35,000 deaths, highlighting the urgent need for innovative strategies to address this crisis,\u201d Sors said.<\/p>\n\n\n\n

\u201cAccording to the NIH, CDC and the Infectious Diseases Society of America, gram-negative \u2018superbugs\u2019 such as Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii rank among the most dangerous multidrug-resistant microorganisms. Regrettably, the development of new antibiotics is lagging, and lung infections triggered by these resistant pathogens can be fatal.\u201d<\/p>\n\n\n\n

Developing inhalation therapeutics for the lungs<\/strong><\/h2>\n\n\n\n

Zhou said oral or intravenous administrations of many antibiotics are often not effective for treatment of lung infections in many patients due to very limited drug exposure at the infection site and systemic toxicity. <\/p>\n\n\n\n

\u201cThis makes lung infections caused by resistant bacteria extremely difficult to treat, reflected by the fact that lung infections are the fourth leading cause of death in the world,\u201d Zhou said.<\/p>\n\n\n\n

Zhou\u2019s inhalation therapeutics help antibiotics directly reach the infection site in the lungs to better kill the bacteria. Inhaled medicines also can avoid systemic toxicity because much fewer drugs are absorbed into the bloodstream.<\/p>\n\n\n\n

\u201cWe also use the innovative manufacturing techniques of advanced spray drying to incorporate two or more synergistic antibiotics into a single particle so they can deposit at the same site of infection and achieve the maximum bacterial killing synergy,\u201d he said. <\/p>\n\n\n\n

Next development steps<\/strong><\/h2>\n\n\n\n

Preliminary animal studies showed superior bacterial killing capability and reduced toxicity of the new inhalation medicines.<\/p>\n\n\n\n

Zhou said the team\u2019s goal is to develop viable pharmaceutical products to effectively treat resistant bacterial lung infections. The NIH funding will be utilized to optimize the formulation and generate preclinical data for potential filing of a New Drug Application.<\/p>\n\n\n\n

\u201cZhou\u2019s cutting-edge research is a true breakthrough and perfectly exemplifies Purdue\u2019s commitment to fight the global crisis of antimicrobial resistance,\u201d said Eric Barker<\/a>, the Jeannie and Jim Chaney Dean of Purdue\u2019s College of Pharmacy.<\/p>\n\n\n\n

Zhou disclosed the inventions of inhalation medicines to the Purdue Innovates Office of Technology Commercialization<\/a>, which has applied for patents to protect the intellectual property. Industry partners interested in developing or commercializing the work should contact Joe Kasper, assistant director of business development and licensing \u2014 life sciences, at jrkasper@prf.org<\/a>. <\/p>\n\n\n\n

About Purdue Innovates Office of Technology Commercialization<\/strong><\/h2>\n\n\n\n

The Purdue Innovates Office of Technology Commercialization<\/a> operates one of the most comprehensive technology transfer programs among leading research universities in the U.S. Services provided by this office support the economic development initiatives of Purdue University and benefit the university\u2019s academic activities through commercializing, licensing and protecting Purdue intellectual property. In fiscal year 2023, the office reported 150 deals finalized with 203 technologies signed, 400 disclosures received and 218 issued U.S. patents. The office is managed by the Purdue Research Foundation, which received the 2019 Innovation & Economic Prosperity Universities Award for Place from the Association of Public and Land-grant Universities. In 2020 IPWatchdog Institute ranked Purdue third nationally in startup creation and in the top 20 for patents. The Purdue Research Foundation is a private, nonprofit foundation created to advance the mission of Purdue University. Contact otcip@prf.org<\/a> for more information.<\/p>\n\n\n\n
