EMA issues advice on casirivimab and imdevimab antibody cocktail for the treatment of mild-to-moderate COVID-19

Share
  • CHMP has completed a review of available data for investigational antibody cocktail casirivimab and imdevimab (REGN-COV2) to be considered for the treatment of confirmed COVID-19  
  • CHMP scientific opinion supports national decision making within EU states on the use of the antibodies before a formal authorisation is granted during a public health emergency
  • Roche and Regeneron are collaborating on developing and manufacturing casirivimab and imdevimab; Roche will be responsible for distribution in Europe and other countries outside the US

Basel, 26 February 2021 - Roche (SIX: RO, ROG; OTCQX: RHHBY) confirmed today that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has issued a scientific opinion supporting the use of the investigational antibody cocktail, casirivimab and imdevimab, as a treatment option for patients with confirmed COVID-19 who do not require oxygen supplementation and who are at high risk of progressing to severe COVID-19.

The CHMP’s scientific opinion (under Article 5(3) of Regulation 726/2004) provides a harmonised, EU-level opinion on the efficacy, quality and safety of casirivimab and imdevimab. This review took place in parallel to the EMA’s ongoing rolling review process, which is used to speed up the formal marketing application assessment of a promising medicine during a public health emergency. Under Article 5(3), the CHMP assessed available data in patients with COVID-19, including data from the REGN-COV2 2067 trial, as well as supportive data from other settings.

“This advice by the CHMP regarding casirivimab and imdevimab is an important step towards addressing the COVID-19 pandemic in the EU,” said Levi Garraway, M.D., Ph.D., Chief Medical Officer and Head of Global Product Development. “Initial data showed that patients treated with this investigational antibody cocktail saw a reduction in both viral loads and medically-attended visits. Together with our partner Regeneron, we will continue working with the EMA, governments and other health authorities across the globe to bring this antibody cocktail to as many patients as possible.”

Roche and Regeneron are collaborating to develop, manufacture and distribute casirivimab and imdevimab, to people around the globe, with the aim of having more than two million doses available in 2021. Regeneron will be responsible for distributing the antibody cocktail in the US and Roche will be responsible for distribution outside the US, with the first Roche-manufactured doses already being distributed. Casirivimab and imdevimab could provide a much-needed treatment option for infected individuals already experiencing symptoms of COVID-19, and may be able to prevent infection in people exposed to the virus, and hopefully help slow the spread of the global pandemic. 

The investigational antibody cocktail of casirivimab and imdevimab continues to be evaluated in clinical trials in multiple settings for COVID-19: in non-hospitalised and certain hospitalised patients, including the open-label RECOVERY trial of hospitalised patients in the UK, and a trial for the prevention of COVID-19 in household contacts of infected individuals. As of February 2021, approximately 23,000 people have participated in casirivimab and imdevimab clinical trials. Lower doses of casirivimab and imdevimab are also being studied with the aim of increasing the number of patients who could potentially be treated if the cocktail is approved.

In these exceptional times, Roche stands together with society, governments, healthcare providers and all those working to overcome the pandemic.

About the CHMP’s review under Article 5(3) of Regulation 726/2004
The intent of the Article 5(3) referral procedure is for the CHMP to develop a harmonised scientific opinion at the EU level on the quality, safety and efficacy of a medicine based on the currently available data. The scientific opinions can then be considered by EU member states when making decisions on the use of medicines at a national level before a formal authorisation is issued.

The review under Article 5(3) of Regulation 726/2004 was requested by the EMA’s Executive Director following preliminary discussions with the COVID-19 EMA pandemic task force (COVID-ETF), which brings together experts from across the European medicines regulatory network to advise on the development, authorisation and safety monitoring of medicines and vaccines for COVID-19.

About casirivimab and imdevimab
Casirivimab and imdevimab is a cocktail of two monoclonal antibodies (also known as REGN10933 and REGN10987, respectively) and was designed by Regeneron scientists to block infectivity of SARS-CoV-2, the virus that causes COVID-19. They evaluated thousands of fully-human antibodies produced by the company's proprietary VelocImmune® mice, which have been genetically modified to have a human immune system, as well as antibodies identified from humans who have recovered from COVID-19.

The two potent, virus-neutralising antibodies that form casirivimab and imdevimab are believed to bind non-competitively to the critical receptor binding domain of the virus's spike protein, which is hypothesised to diminish the ability of mutant viruses to escape treatment and to protect against spike variants that may arise in the human population, as detailed in recent Science publications.

Casirivimab and imdevimab have not been approved by any health authority. In November 2020, the antibody cocktail was authorised by the U.S. Food and Drug Administration (FDA) under an Emergency Use Authorization (EUA) for the treatment of mild to moderate COVID-19 in adults and paediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progressing to severe COVID-19 and/or hospitalisation. The US EUA is temporary and does not take the place of the formal biologics license application (BLA) submission, review and approval process.

Casirivimab and imdevimab’s development, manufacturing and clinical trials have been funded in part by the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services under OT number: HHSO100201700020C.

About Roche’s response to the COVID-19 pandemic
As a leading healthcare company we are doing all we can to support countries in minimising the impact of COVID-19.  We have developed a growing number of diagnostic solutions that help to detect and diagnose the infection in patients, as well as providing digital support to healthcare systems, and we continue to identify, develop and support potential therapies which can play a role in treating the disease.

We understand the impact of COVID-19 goes beyond those who contract it, which is why we are working with healthcare providers, laboratories, authorities and organisations to help make sure that patients continue to receive the tests, treatment and care they need during these challenging times. As we learn from the pandemic, we are partnering with governments and others to make healthcare stronger and more sustainable in the future.

Our diagnostics solutions:
Reliable, high-quality testing is essential to help healthcare systems overcome this pandemic. Our portfolio includes:

  • a high-volume molecular test to detect SARS-CoV-2, the virus that causes COVID-19, (FDA Emergency Use Authorisation (EUA) and available in countries accepting the CE Mark)
  • a SARS-CoV-2 laboratory-based antibody test, aimed at detecting the presence of antibodies in the blood targeting the nucleocapsid (FDA EUA and CE Mark)
  • an IL-6 test to assist in identifying severe inflammatory response in patients with confirmed COVID-19 (FDA EUA and CE Mark)
  • Roche v-TAC, which could help simplify the screening, diagnosis and monitoring of patients with respiratory compromise in the current COVID-19 pandemic
  • a SARS-CoV-2 rapid antibody test to help determine at the point of care whether a person has been exposed to the virus (CE Mark)
  • a rapid antigen test to support in the detection of SARS-CoV-2 at the point of care within 15 minutes (CE Mark)
  • a high-volume molecular test to simultaneously detect and differentiate between SARS-CoV-2 and influenza A/B, as the symptoms are similar for both (FDA EUA and CE Mark)
  • a second SARS-CoV-2 antibody test, aimed at measuring the spike protein to support vaccination development and complement our existing portfolio
  • a point-of-care molecular PCR test that simultaneously detects and differentiates between SARS-CoV-2 and influenza A/B infections to support urgent triage and diagnosis (FDA EUA and CE Mark)

Our research into therapies:
Roche is committed to improving the treatment of COVID-19. We are actively involved in understanding the potential of our existing portfolio and are exploring the potential of our investigational molecules.  

There have been/are a number of clinical trials with an external 3rd party as the sponsor exploring the efficacy and safety of Actemra (tocilizumab) for the treatment of COVID-19 associated pneumonia. COVACTA and EMPACTA, sponsored by Roche, are the first global phase III, multi-centre, randomised, placebo-controlled studies evaluating Actemra in this setting.

We continue to evaluate the data from the global COVACTA study, which did not meet its primary endpoint as announced on 29 July 2020, in conjunction with results from the global EMPACTA study of Actemra in COVID-19 pneumonia, which met its primary endpoint as announced on 17 September 2020, as well as additional data sources that are in the public domain to determine whether a population can be defined based on patient and disease characteristics in which Actemra on top of usual care may provide a favourable benefit risk profile.

Roche remains committed to continuing the Actemra clinical trial programme in COVID-19 to further explore Actemra in other treatment settings, including in combination with an antiviral. 
In August 2020 we signed a collaboration agreement with Regeneron on developing, manufacturing and significantly increasing global supply of an investigational antibody cocktail for COVID-19 if it proves safe and effective in clinical trials and regulatory approvals are granted.

In October 2020 we signed an agreement with Atea to jointly develop AT-527, an orally administered direct-acting antiviral (DAA) currently in phase II clinical trials. AT-527 has the potential to be the first novel oral antiviral to treat COVID-19 patients outside the hospital setting, as well as in the hospital, and may also be used in post-exposure prophylactic settings.

NEW YORK, April 23, 2021 (GLOBE NEWSWIRE) -- The rapidly evolving global market for cryptocurrency is currently abuzz with the recent introduction of three extraordinarily designed mining rigs, BT, DBT and GBT from BitWats (www.bitwats.com). Instead of focusing only on highly proficient and technology savvy mining stalwarts, these three products were created to allow the casual enthusiasts as well as small-time miners to make their fortune out of crypto mining. DBT offers hash rates of 750 TH/s, 70 GH/s, 5 GH/s, and 5 MH/s, for bitcoin, litecoin, ethereum, and monero respectively. On the other hand, for GBT Miner, the hash power in the same order are 2250 TH/s, 210 GH/s, 15 GH/s, and 15 MH/s. The power consumptions for these two units are 900W and 2200W respectively. Based on figures mentioned above, monthly profit making potential of the two units is as mentioned below. DBT Miner: $7,500 (Bitcoin), $13,000 (Litecoin), $13,000 (Ethereum), and $15,000 (Monero)GBT Miner: $22,500 (Bitcoin
