Kither Biotech is a biopharma company founded by Prof. Alessandra Ghigo, Prof. Emilio Hirsch, Prof. Alberto Bardelli and Marco Kevin Malisani. The company aims to identify and develop new drug candidates for the treatment of rare pulmonary diseases, with specific focus on cystic fibrosis and idiopathic pulmonary fibrosis. Kither Biotech is a spin-off from the University of Turin and actively collaborates with the Molecular Biotechnology Center (University of Turin) and other research centres in the world. The company developed a pipeline of treatments currently under preclinical development, with programs in cystic fibrosis, idiopathic pulmonary fibrosis and other respiratory diseases. | www.kitherbiotech.com About KIT2014

KIT2014 is a cell-permeable cAMP modulating peptide that disrupts the interaction of PI3Kgamma with its partner, protein kinase A (PKA), leading to type 3 and 4 phosphodiesterases (PDE3/4) inhibition and, in turn, to enhanced cAMP responses within the cell. KIT2014 is currently being investigated for the treatment of cystic fibrosis (CF) as an add-on inhalation therapy to the current standard of care, enabling improved efficacy by directly impacting mucus hypersecretion, airway inflammation and bronchoconstriction, the most significant ailments of CF patients. When inhaled, KIT2014 increases cAMP locally in bronchial epithelial cells to promote the opening of CFTR chloride channels, which are key to mucus hydration, while in lung smooth muscle and immune cells cAMP elevation limits bronchoconstriction and neutrophil infiltration. In CF patients, treatment with KIT2014 is believed to restore the function of CFTR mutants by potentiating the effects of CFTR modulators (Ghigo et al., Science Translational Medicine, in press).
