TGA grants provisional approval for Celltrion’s regdanvimab (regkirona)


·        The monoclonal antibody treatment is provisionally approved for the intravenous treatment of mild-to-moderate COVID-19 patients in Australia[1]

December 7, 2021, INCHEON, KOREA Celltrion Healthcare Australia Pty Ltd announced that the Therapeutic Goods Administration (TGA) granted provisional approval for the use of regdanvimab (regkirona) in adult patients with COVID-19 who do not require supplemental oxygen and who are at increased risk of progressing to severe COVID-19.

Monoclonal antibodies are proteins designed to attach to a specific target, in this case the spike protein of SARS-CoV-2, which works to block the path the virus uses to enter human cells. The TGA's decision is based on the efficacy and safety data in the global phase III clinical trial involving more than 1,315 people in 13 countries including the U.S., Spain, and Romania. Data showed regdanvimab (regkirona) reduced the risk of COVID-19 hospitalisation by 72% for patients at high-risk of progressing to severe COVID-19 and shorted the time for improving clinical symptoms by more than 4.7 days.

“Today’s provisional approval in Australia marks an important milestone in the fight against COVID-19 as monoclonal antibodies have proven to be an important therapeutic option in the ongoing battle against COVID-19,” said Dr. HoUng Kim, Ph.D., Head of Medical and Marketing Division at Celltrion Healthcare. “We are now a step closer to providing a safe and effective monoclonal antibody treatment for patients at high-risk of progressing to severe COVID-19 in Australia.”

To date, regdanvimab has received market authorisation by the European Medicines Agency (EMA). It has also been granted regulatory approval in the Republic of Korea and emergency use authorisations in Indonesia, Brazil and conditional approval in Peru.

About regdanvimab (CT-P59)

CT-P59 was identified as a potential treatment for COVID-19 through screening of antibody candidates and selecting those that showed the highest potency in neutralising the SARS-CoV-2 virus. In vitro and in vivo pre- clinical studies showed that CT-P59 strongly binds to SARS-CoV-2 RBD and significantly neutralises the wild type and mutant variants of concern. In in vivo models, CT-P59 effectively reduced the viral load of SARS-CoV-2 and inflammation in lung. Results from the global phase I and phase II/III clinical trials of CT-P59 demonstrated a promising safety, tolerability, antiviral effect and efficacy profile inpatients with mild-to-moderate symptoms of COVID-19.[2] The EC granted marketing authorisation for Celltrion’s regdanvimab following positive opinion by the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) in November 2021.
