Positive data from Phase II study ATTRACT in patients with COVID-19 published online
With close to 100 million registered cases and 2 million deaths to date, there is an urgent need for a safe oral effective therapy to complement the recently launched vaccines. Vicore Pharma’s angiotensin II type 2 receptor (AT2R) agonist C21 showed restoration of respiratory function with a significantly lower risk of being on supplemental oxygen at the end of treatment and during follow up.
The results are now available as a preprint at www.medrxiv.org/content/10.1101/2021.01.26.21250511v1 and have been submitted for publication in a peer reviewed journal.
“The complete analysis confirms the initial observation that C21 is safe, restores lung function and reduces the need for oxygen supplementation in these critically ill COVID-19 patients”, said Carl-Johan Dalsgaard, CEO of Vicore Pharma.
In the ATTRACT study (Angiotensin II Type Two Receptor Agonist COVID-19 Trial), a randomized, double-blind and placebo-controlled trial, a total of 106 hospitalized patients with a diagnosis of coronavirus SARS-CoV-2 infection (confirmed by polymerase chain reaction test) and signs of an acute respiratory infection but not requiring mechanical ventilation were recruited. The patients were randomized to receive oral treatment with C21 (100 mg b.i.d., n=51) or placebo (n=56) for seven days on top of standard of care (physician’s choice) with a follow up after 7-10 days. According to data analyzed to date, the treatment groups were well balanced regarding age, sex and concomitant medications. Importantly, the vast majority of patients received corticosteroid treatment.
C21, a first-in-class AT2R agonist
C21 is a first-in-class orally available low molecular weight angiotensin II type 2 receptor (AT2R) agonist that activates the “protective arm” of the renin-angiotensin system (RAS). The compound has shown robust effects in human IPF lung slices, and a phase II proof-of-concept study in IPF has recently started. Given that AT2R agonism has therapeutic potential in a number of additional indications with significant unmet needs, Vicore has intensified the efforts to develop proprietary follow-up molecules with different profiles.
The ATTRACT study received £1.5 million in funding from the UK charity LifeArc – Coronavirus (COVID-19) Therapeutics – https://www.lifearc.org/funding/COVID-19-funding-2/ – a £10 million fund launched on 20 March 2020 to support research and testing of therapeutics that could be rapidly deployed to help address COVID-19.
