SNG001 is an inhaled drug that contains a antiviral protein called interferon beta (IFN-β). IFN-β in produced in the lungs during viral lung infections. It has been shown that older people and people with some chronic diseases have an IFN-β deficiency. Many viruses inhibit IFN-β as part of their strategy to evade the immune system.
Addition of IFN-β in vitro protects lung cells from viral infection. IFN-β protects cells against the MERS and SARS coronaviruses (close relatives of SARS-CoV-2, the virus that causes COVID-19).
SNG001 is an inhaled formulation of interferon beta-1a it is currently in Phase II clinical trials for COPD patients.
Synairgen has conducted randomised placebo controlled clinical trials of SNG001 involving >200 asthma and COPD patients. These trials have shown that SNG001 has:
- been well tolerated during virus infections
- enhanced antiviral activity in the lungs (measured in sputum and blood samples)
- provided significant lung function benefit over placebo in asthma in two Phase II trials.
Synairgen believes SNG001 could help prevent worsening or accelerate recovery of severe lower respiratory tract illness in COVID-19 patients.
Patients who are in hospital or non-hospitalised but are a high risk groups (e.g. elderly or diabetics) will be invited to take part in the trial. The patient would receive either SNG001 or placebo once daily for 14 days. The severity of the patients condition would be recorded on a scale developed by the World Health Organisation and the patient would be asked questions about their breathlessness, cough and sputum every day, as well as assess their general medical condition and safety.
If SNG001 proves to be beneficial it would be a major breakthrough for the treatment of COVID-19.
