Pneumagen Highlights Broad-Spectrum Antiviral Activity of First-in-Class Intranasal Drug Neumifil in New Publication

  • Pneumagen has previously reported positive results from both Phase 1 and a clinical proof of concept Phase 2 Human Influenza Challenge study demonstrating the potential of Neumifil
  • New preclinical data, published in peer-reviewed journal Antiviral Research, show Neumifil demonstrates broad-spectrum efficacy against a wide range of viruses including influenza virus, respiratory syncytial virus, coronavirus and rhinovirus
  • These studies confirm Neumifil’s ability to block virus engagement of host receptors to inhibit infection with reduced risk of antiviral resistance
  • Findings support further clinical development of Neumifil in vulnerable populations to provide broad-spectrum protection against recurring seasonal infections or newly emerging viral threats

St Andrews, UK – 3 July 2024 – Pneumagen, a clinical stage biotech company developing Neumifil (HEX17), a broad-spectrum antiviral, intranasal drug for the prophylaxis and treatment of viral respiratory tract infections (RTIs), announces the publication of new preclinical data evaluating Neumifil in a wide range of viral disease models. These preclinical data are published in the peer-reviewed journal, Antiviral Research in a paper entitled, “HEX17(Neumifil): An intranasal respiratory biotherapeutic with broad-acting antiviral activity,” and confirm the potential of Neumifil as a first in class protein-based antiviral prophylactic for respiratory viral infections. The article can be accessed online at https://doi.org/10.1016/j.antiviral.2024.105945.

The publication highlights that Neumifil (HEX17) demonstrates consistent broad-spectrum efficacy against a wide range of viral respiratory pathogens including influenza virus, respiratory syncytial virus, coronavirus and human rhinovirus in multiple in vivo and in vitro studies. These viruses pose a severe threat to human health, particularly in the very young or old, or in those with pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD).

This new research, showing protection against multiple key respiratory pathogens, taken together with a previously reported positive Phase 2 human influenza challenge study, which demonstrated an encouraging clinical safety and efficacy profile (Phase 2 Results here) is strongly supportive of further clinical development of Neumifil for the prevention of respiratory viral infections in high-risk subjects, such as those with COPD.

Professor Garry Taylor, Chair of the Scientific Advisory Board of Pneumagen said: “There is an urgent need for broad-acting antiviral strategies to prevent respiratory tract infections. Emerging or re-emerging viral diseases, including most recently H5N1, caused by new or genetic variants of existing viruses represent a severe threat to human health, particularly in those with pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). As confirmed by this comprehensive early preclinical data set, Neumifil shows great promise as a potential wide-ranging antiviral prophylactic that could significantly reduce the risk and severity of infections in these high-risk groups, ensuring better health outcomes and providing an important new weapon against existing and emerging viral threats.”

Douglas Thomson CEO of Pneumagen added: “Publication of the impressive results from our wide-ranging preclinical studies with Neumifil provides important confirmation of its broad-spectrum activity. Based on our early data, we have moved rapidly to progress Neumifil into clinical development and our positive Phase 1 and Phase 2 CHIM studies further reinforce our confidence in Neumifil as a potentially important treatment option for at-risk patients. We now look forward to advancing Neumifil into further clinical studies where its broad spectrum of activity offers significant promise. These trials are expected to include the evaluation of Neumifil’s ability to reduce the incidence of exacerbations in COPD patients.”

Pneumagen Presents Positive Phase 2 Influenza Human Challenge Study data on Neumifil, its Broad-Spectrum Antiviral Drug, at the American Thoracic Society (ATS) 2024 Conference

  • Neumifil delivers statistically significant reductions in influenza symptomatic infection rate, symptom severity and viral load
  • Strategy to advance clinical development of Neumifil to be based on these positive data and pre-clinical data package demonstrating Neumifil’s activity against a broad range of viruses

St Andrews, UK – 23nd May 2024 – Pneumagen, a clinical stage biotech company developing Neumifil (HEX17), a broad-spectrum antiviral, intranasal drug for the prophylaxis and treatment of viral respiratory tract infections (RTIs), presented positive results from its Phase 2, proof-of-concept, Controlled Human Infection Model (CHIM) study in which healthy volunteers were challenged with influenza virus following administration of Neumifil. These data were featured during an oral presentation* at the American Thoracic Society (ATS) in San Diego on 21st May.

The presentation, entitled “HEX17, a Novel Broad-spectrum Antiviral Intranasal Drug, Demonstrates Efficacy Against Influenza in a Controlled Human Infection Model Conducted in Healthy Adults,” was delivered by Dr Geoff Kitson, Chief Medical Officer of Pneumagen.

“We are very pleased to present detailed data from our Phase 2 Clinical trial of Neumifil,” said Douglas Thomson, Chief Executive Officer of Pneumagen. “Based on these promising proof-of-concept results presented at ATS, that reinforce the clinically significant reduction in both the incidence and severity of symptomatic influenza infection, we now look forward to advancing Neumifil into further clinical studies where its broad spectrum of activity offers significant potential. These trials are expected to include the evaluation of Neumifil’s ability to reduce the incidence of exacerbations in patients with Chronic Obstructive Pulmonary Disease (COPD), which represents a significant at-risk population.”

Dr Geoff Kitson, Chief Medical Officer and presenting author, commented “Viral respiratory infection is of enormous global concern, particularly in patients with underlying pulmonary disease, in whom viral infections can induce exacerbations. The significant reductions in both symptoms and viral load, demonstrate the potential of this new antiviral drug not only to alleviate patients suffering but also to curtail the spread of virus within communities.

Neumifil’s activity in protecting against a broad range of viral infections shows it has the potential to become an important medicine for the prevention of exacerbations in people with COPD or asthma.”

Key highlights from the presentation delivered at ATS:

  • Randomised, double-blind, placebo-controlled study conducted at a single centre in the UK
  • Study in healthy adults evaluating two dosing regimens (single dose, 3 days before infection or three daily doses on the three days leading up to infection with influenza virus) of Neumifil, administered as an intranasal spray to participants who were subsequently infected with influenza virus
  • Neumifil demonstrated a clinically significant reduction in the incidence of symptomatic influenza infection
  • Neumifil significantly reduced viral load and severity of symptoms compared to placebo
  • Neumifil was well tolerated with a safety profile in line with data from the first in human study
