Kither Biotech has announced the successful completion of its Phase I clinical study of KIT2014 for respiratory diseases in healthy participants. 

“We are pleased to report the successful completion of this first-in-human Phase I study with KIT2014, a significant milestone for Kither Biotech,” said Dr Dimitrios Goundis, CEO of Kither Biotech. “The study results demonstrate KIT2014’s favourable safety and tolerability profile.

“The unique ability of KIT2014 to increase cAMP in different airway cell types offers the potential for multiple therapeutic benefits, including bronchodilation and anti-inflammatory effects. We look forward to advancing the clinical development of KIT2014, to assess its therapeutic potential in patients with respiratory diseases including COPD, NCFB and CF.” 

“We are delighted that this first-in-human study has successfully demonstrated that inhaled KIT2014 was safe and well tolerated across all dose levels evaluated, with no measurable systemic exposure,” added Anita van der Meer, Director of Kither Biotech Pty. “These findings support the continued clinical development of KIT2014 and provide a strong foundation for advancing into patient studies in COPD, where we aim to further explore its unique multimodal mechanism of action and potential to address important unmet medical needs.” 

KIT2014 is a novel cell-permeable peptide delivered via inhalation, which is designed to address multiple pathological pathways common to a number of major respiratory diseases. The drug, which consists of 42 amino acids, acts to promote bronchodilation and reduce lung inflammation.  

It does this through balanced dual inhibition of the enzymes phosphodiesterase 3 and 4 (PDE3/4), which increases local concentrations of the key signalling molecule cAMP (cyclic adenosine monophosphate). KIT2014 is being developed for a number of respiratory diseases including COPD, NCFB and CF.
