Celltrion’s Monoclonal Antibody Treatment for COVID-19, regdanvimab (CT-P59), Demonstrates Strong Neutralising Activity Against Delta Variant

    • Pre- scientific information for regdanvimab (CT-P59) demonstrates strong neutralising activity versus the Delta variant (B. 1.617.2, initially determined in India); results show 100% survival rate with virus elimination from all animals treated with therapeutic dosage of CT-P59
    • Regdanvimab (CT-P59) likewise kept its neutralisation potency against the Lambda version (C. 37, initially recognized in Peru) utilizing a pseudo-virus neutralisation assay
    • Celltrion reveals arise from the worldwide Phase III scientific trial of regdanvimab (CT-P59) at ECCMID 2021; data met all primary and key secondary endpoints

    Celltrion Group today revealed new results from an in vivo efficacy research study showing that regdanvimab (CT-P59) has a strong neutralising result versus the quickly spreading out Delta variation (B. 1.617.2, initially identified in India).

    According to the World Health Organization (WHO), the Delta version has been reported in 96 nations ending up being the most common alternative.1 The pre-clinical

    in vivo research study evaluated the neutralisation impact of CT-P59 versus the Delta variation, using a scientifically pertinent dosage. The research study demonstrated that CT-P59 treatment results in a 100% survival rate from COVID-19 compared to 0% for the placebo group, with significant defense versus body weight loss revealed after viral obstacle also seen. In addition, a healing dose of CT-P59 considerably decreased the viral load of SARS-CoV-2 and inflammation in the lungs compared to non-treated controls with virus removal from all animals treated with CT-P59.

    Taken together, CT-P59 has actually shown in vivo efficacy against Delta variation following Beta (B. 1.351, first determined in South Africa)2 and Gamma variant (P. 1, initially identified in Brazil)3, which was equivalent to that against wild type SARS-CoV-2, hence showing that in spite of the minimized in vitro neutralising activity against Variants of Concern (VOC), CT-P59 maintained its therapeutic strength in in vivo setting.

    The monoclonal antibody CT-P59 likewise showed strong neutralising ability versus the Lambda variation (C. 37, initially recognized in Peru) in a cell-based pseudo- virus assay study performed by the National Institutes of Health (NIH), U.S.

    “& ldquo; These new data are encouraging and reinforcing our body of both pre- scientific and clinical data,” & rdquo; said Dr. HoUng Kim, Ph.D., Head of Medical and Marketing Division at Celltrion Healthcare. “& ldquo; The Delta variant is a infectious and extremely transmissible version that could prompt additional waves of infection worldwide. It is very important to broaden the arsenal of monoclonal antibody treatments that are wanted to remain reliable versus the emerging COVID-19 variations.”

    & rdquo; Celltrion revealed its full Phase III information at the 31 st European Congress of Clinical Microbiology & & Infectious Diseases (ECCMID) which happened online from 9 -12 July 2021. During the oral session, data showed regdanvimab (CT-P59) substantially minimized the danger of COVID-19 related hospitalisation or death by 72% for patients at high- threat of progressing to extreme COVID-19 and 70% for all clients. In addition, patients who were treated with regdanvimab (CT-P59) reported a considerably reduced time to clinical recovery by a minimum of 4.7 days for clients at high- danger of progressing to extreme COVID-19 and by 4.9 days compared to placebo for all clients.

About regdanvimab (CT-P59 )CT-P59 was determined as a possible treatment for COVID-19 through screening of antibody prospects and selecting those that revealed the greatest effectiveness in neutralising the SARS-CoV-2 infection. In vitro and in vivo pre-medical research studies showed that CT-P59 strongly binds to SARS-CoV-2 RBD and substantially neutralise the wild type and mutant variations of issue including the Alpha variation (B. 1.1.7, initially recognized in the UK). In in vivo models, CT-P59 effectively lowered the viral load of SARS-CoV-2 and inflammation in lung. Arise from the worldwide Phase I and II clinical trials of CT-P59 demonstrated a promising security, tolerability, antiviral impact and

    effectiveness profile in patients

    with mild -to-moderate symptoms of COVID-19.4 Celltrion likewise has recently commenced the development of a neutralising antibody mixed drink with CT-P59 against brand-new emerging variants of SARS-CoV-2.
