CAMBRIDGE, Mass., Oct. 02, 2024 (GLOBE NEWSWIRE) -- Spero Therapeutics, Inc. (NASDAQ:SPRO), a multi-asset clinical-stage biopharmaceutical company, focused on identifying and developing novel treatments for rare diseases and multi-drug resistant (MDR) bacterial infections, today announced the publication of data from its Phase 1 clinical trial, which assessed the intrapulmonary pharmacokinetics (PK) of SPR719. The full manuscript, titled "Intrapulmonary pharmacokinetics of SPR719 following oral administration of SPR720 to healthy volunteers" was published ahead of print in Antimicrobial Agents and Chemotherapy. A copy of the paper can be accessed here.
SPR720 is an oral, chemically stable phosphate ester prodrug that is converted rapidly in vivo to SPR719, the active moiety. SPR719 targets the ATPase site of DNA gyrase B in mycobacteria, a mechanism that is distinct from that of other antibiotics in use for Non Tuberculous Mycobacterial- Pulmonary Disease (NTM-PD).
"The Phase 1 study is part of a series of studies Spero is conducting in order to explore the potential of SPR720 as a treatment for NTM-PD," said Sath Shukla, President and CEO of Spero. "Effective oral therapy for NTM lung disease requires adequate uptake into the pulmonary epithelial lining fluid and alveolar macrophages, where mycobacteria reside and proliferate. The results of this Phase 1 study suggest that SPR719 (the active moiety of SPR720) had significant lung uptake and enhanced concentrations in these compartments."

Upcoming Presentation at IDWeek
Data from in vitro evaluation of the development of microbial resistance against SPR719 have been accepted for presentation at IDWeek, taking place October 16 to 19, 2024 in Los Angeles, CA.
About Nontuberculous Mycobacterium Pulmonary Disease (NTM-PD)
NTM-PD, also known as NTM lung disease, is caused by bacteria naturally found in soil, dust, and water. These bacteria belong to the Mycobacterium family, excluding those that cause tuberculosis and leprosy. The most common cause of NTM infections is the Mycobacterium avium complex (MAC). NTM is a growing global health concern with significant unmet medical need. Although rare, the incidence of NTM pulmonary disease is increasing worldwide. It is estimated that approximately 130,000 patients suffer from NTM in the U.S. and Europe, a figure that is growing at a rate of 8% annually. Patients with NTM lung disease experience progressive symptoms, lung damage, and reduced quality of life due to chronic symptoms and impaired lung function. NTM infections can occur after surgery, trauma, injections, or exposure to contaminated water. Prevention involves effective water management programs in healthcare facilities, and treatment typically requires consultation with infectious disease or pulmonary specialists. Patients currently have limited treatment options for NTM lung disease.
