Ronapreve approved by Swissmedic to treat non-hospitalised COVID-19 patients and for prophylaxis of the disease

  • In the fight against the Coronavirus, Ronapreve marks an additional treatment option
  • Approval based on data demonstrating Ronapreve reduced risk of hospitalisation or death in certain patients with mild to moderate disease and reduced risk of COVID-19 infections in people exposed to the virus

Basel, 27 December 2021 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the Swiss agency for therapeutic products (Swissmedic) has approved Ronapreve™ (casirivimab and imdevimab), for the treatment of confirmed COVID-19 in adult and in adolescent patients (12 years of age or older and weighing at least 40 kg) who do not require supplemental oxygen or hospitalisation for COVID-19 and who are at high risk of progressing to severe COVID-19. Ronapreve is also indicated for the prevention of COVID-19 in adult and in adolescent patients (12 years of age and older and weighing at least 40kg) who are not able to mount an appropriate immune response to the SARS-CoV-2 vaccination.

“It is good news that Ronapreve is now fully authorised in Switzerland and that we were able to complete the rolling authorisation process together with Swissmedic in a joint effort”, said Jean-Marc Häusler, M.D., Roche's Country Medical Director in Switzerland.

The decision from Swissmedic is based on the review of positive data from the REGN-COV 2067 treatment study in non-hospitalised patients and the REGN-COV 2069 prophylaxis study in people exposed to SARS-CoV-2 virus. Roche will continue to work with Swissmedic to potentially extend the marketing authorisation of Ronapreve to treat hospitalised patients with COVID-19.

Ronapreve has already been available to patients in Switzerland since mid-May 2021 under the so-called declaratory order by Swissmedic following the listing of the antibody combination of casirivimab and imdevimab on Annex 5 of Covid-19 Regulation 3 by the Federal Council on 14 April 2021. More than 2500 patients were already treated with Ronapreve in Switzerland under this declaratory order.

Ronapreve has shown1 to retain its activity against all other main variants of concern, including Delta (B.1.617.2), however, it does not retain efficacy against Omicron. Together with Regeneron, Roche will continue to constantly monitor and rapidly assess its neutralising activity against future emerging variants of concern and respond accordingly.

Outside of Switzerland, Ronapreve has been approved for use in the EU, in Japan and conditionally in the United Kingdom and Australia, and is authorised for emergency or temporary pandemic use in additional territories, including the United States, India and Canada. Ronapreve, being jointly developed by Roche and Regeneron, is currently available in nearly 50 countries via bilateral purchase agreements across many geographies and economies, including lower middle-income countries. In addition, the World Health Organization recommended the use of Ronapreve for the treatment of patients with COVID-19.

About Ronapreve™ (casirivimab and imdevimab)
The efficacy and safety of Ronapreve™ (casirivimab and imdevimab, known as REGEN-COV®in the United States) have been studied across multiple phase III clinical trials in non-hospitalised and hospitalised COVID-19 patients, and in the preventive setting. In addition, data from preclinical studies showed that Ronapreve retained neutralisation activity against key emerging variants, as referenced in publications in Cell and Nature.

The decision from the European Commission is based on data from multiple studies, including:

  • the REGN-COV 2067 study, showing that Ronapreve reduced hospitalisation or death by 70% and symptom duration by four days.
  • the REGN-COV 2069 study, showing that the administration of Ronapreve reduced the risk of symptomatic infections by 81% in those who were not infected when they entered the trial.

There have been no new safety signals identified for Ronapreve in these studies.

Ronapreve is being jointly developed by Roche and Regeneron. It is a combination of two monoclonal antibodies, casirivimab and imdevimab, and was designed to block infectivity of SARS-CoV-2, the virus that causes COVID-19.
