Synairgen’s H1 2023 results re-established management’s commitment to progressing its lead respiratory anti-viral asset SNG001 through clinical development. The results of the Phase III SPRINTER trial and the US Government’s ACTIV-2 trial produced valuable data suggesting SNG001 has potential to reduce the risk of disease progression, especially in more severely affected and higher risk patient populations. The company is currently undertaking patient identification activities to select patients most likely to benefit from SNG001 and inform future study designs. Synairgen is also looking to expand into other populations of interest such as those ventilated with viral pneumonia and immunocompromised patients who are unable to clear respiratory viruses. H1 2023 net cash stood at £14.6m, which, at the current run rate, provides an operational cash runway into H2 2024. This estimate includes existing committed costs as well as the estimated costs of a planned observational study and two investigator-led/Synairgen-sponsored Phase II studies. We will look to reinstate a target price once we have greater visibility around SNG001’s clinical development strategy and target indications.- Financials. Adjusted operating losses for H1 2023 amounted to £5.1m, significantly lower than the prior period (H1 2022: £13.7m). This was primarily driven by lower R&D expenses (£3.5m vs. £11.1m) due to the conclusion of the Phase III SPRINTER trial in 2022. Net cash outflow from operating activities was £5.3m (H1 2022: £15.8m) with the company reporting an end of period net cash position of £14.6m, which should be sufficient to conduct preparatory Phase III activities for SNG001 and provides a cash runway into H2 2024.
- Don’t count SNG001 out. We remind investors of the body of clinical data to support SNG001’s utility as a broad spectrum anti-viral treatment for severe lung infections. Post-hoc analysis of the SPRINTER study data revealed stronger effects in higher-risk patient subgroups, reducing the risk of severe disease progression or death by 70% compared with placebo. Symptoms of long COVID were also alleviated, with patient treatment responses assessed at days 60 and 90 corresponding to a 35% reduction in the relative risk of fatigue/malaise. Additionally, anti-viral activity has been demonstrated in vitro against respiratory syncytial virus (RSV) and rhinovirus which, in our view, supports SNG001’s potentially extended application across indications.

In our view, the outputs of these should put the company on track towards, potentially registrational, Phase III study in severe anti-viral infections. Management expects these to begin in H1 2024, i
