About Cytos Biotechnology Ltd

Cytos is a public biopharmaceutical company focused on the development of targeted immuno-therapies. The Company’s lead product candidate CYT003 is a novel, first-in-class, immune modulator in Phase 2 clinical development as a potential new treatment for asthma.

In a successfully completed Phase 2a study, CYT003 was shown to maintain asthma control and lung function in patients with persistent allergic asthma despite withdrawal of standard therapy with inhaled corticosteroids. CYT003 has been shown to have a good safety and tolerability profile in more than 450 individuals receiving the active agent so far.
