Posted last night on Reddit: “Nature publication. Role of interferon therapy in severe COVID-19: the COVIFERON randomized controlled trial
https://www.nature.com/articles/s41598-021-86859-y
“ In patients with laboratory-confirmed SARS-CoV-2 infection, as compared with the base therapeutic regiment, the benefit of a significant reduction in TTCI was observed in the IFNß1a arm. This finding needs further confirmation in larger studies.”
It is really interesting and supportive, not only of the general line that IFN 1 has a beneficial effect in Covid-19 but also of the specific case for SNG001.
OK, it is a very small, open label but randomised study, pass the salt please, but, to the extent that it has any validity, there are several key messages in the paper:
1 Patients in both IFN arms seemed to fare better than those in the control arm
2 In the case of the beta 1a arm that superiority was greater and statistically significant whereas in the beta 1b arm it was not.
3 Although the study was not powered to provide statistically valid evidence on mortality, there was a gradient for survival in favour of beta 1a over beta 1b over control. This finding echoes the result in the hospital arm of SG016.
4 These findings were derived with subcutaneous IFN preparations, sub optimal in comparison to nebulised product.
5 Beta 1a is, of course, the form of IFN used in the formulation of SNG001 whereas, critically, beta 1b is the formulation used by Dr Mary and collaborators in Amiens. I have felt for a while that the Amiens operation was the most significant confounding factor in the smooth commercialisation of SNG001. IF the findings in this paper were to be shown, on the basis of further study to be valid, as they relate to the relative performance of 1a and 1b in nebulised form, then the French threat retreats markedly.
So, much food for thought. It would be a mistake to bet the farm on a small and imperfect study like this but, personally, I take comfort from the thrust of its findings.
