A suitably stable formulation of Impentri® in a sterile vehicle had been developed, and further quantities were manufactured for the trial. Vials of Impentri and placebo were shipped, in readiness for the start of the clinical trial, representing the culmination of a 9-month campaign of work.
Efforts then focussed on preparing all necessary regulatory documentation required to initiate the clinical trial. In parallel, 5 clinical sites were recruited across India, with a further 5 back-up sites identified. Regulatory and ethical approvals from the Indian authorities was secured in Aug 2021 and the trial initiated the following month.
Unfortunately, in the Autumn of 2021, COVID-19 infections in India dropped significantly and there were negligible patients requiring hospital ICU treatment. Recognising this significant reduction in patient numbers, the team submitted an amended protocol to the Indian regulators, requesting the additional inclusion of patients with non-COVID 19 pneumonia in the trial, but this was declined. With no expectation of further COVID-19 patients, the trial was terminated.
As the clinical trial was terminated early, there are no project results that can be exploited.
