Celltrion completes enrolment for global Phase II clinical trial with COVID-19 treatment candidate CT-P59

• Celltrion announced enrolment completion of 327 COVID-19 patients in the global Phase II clinical trial
• The trial is designed to evaluate efficacy and safety of CT-P59, an anti-COVID-19 monoclonal antibody treatment candidate
• Celltrion intends to apply for emergency use authorisation (EUA) to the Korean Ministry of Food and Drug Safety (MFDS), conditional on results from the global Phase II clinical trial

INCHEON, South Korea–(BUSINESS WIRE)–Celltrion Group today announced enrolment completion of 327 patients with mild-to-moderate symptoms of SARS-CoV-2 infection in the global Phase II clinical trial of CT-P59, an anti-COVID-19 monoclonal antibody treatment candidate. Celltrion anticipates submission for emergency use authorisation (EUA) to the Korean Ministry of Food and Drug Safety (MFDS), conditional on results from the global Phase II pivotal trial.

The global Phase II clinical trial is a randomised, double-blind, placebo-controlled and parallel-group trial designed to evaluate the efficacy and safety of CT-P59 in combination with standard of care in patients with SARS-CoV-2 infection. The trial enrolled 327 patients with mild-to-moderate symptoms of COVID-19 across three groups (placebo, low concentration, high concentration) and Celltrion is set to obtain the results for global Phase II trial. In addition, Celltrion plans to initiate a global Phase III clinical trial in more than 10 countries in order to obtain more comprehensive safety and efficacy results of CT-P59.

�We managed to successfully enrol 327 patients for the global Phase II trial and the results from the trial are expected in the coming weeks. We plan to compile a robust data set to support the planned emergency use application, expected as early as the end of the year, subject to positive study results,” said Dr. Sang Joon Lee, Senior Executive Vice President of Celltrion. “In order to respond to the global pandemic threat, we are moving forward with our clinical development with the highest urgency and as a key priority.”

In an effort to further address the pandemic, Celltrion has also initiated a post-exposure prophylaxis clinical trial to evaluate the preventive effect and safety of CT-P59 and identify whether this antibody treatment candidate can elicit a neutralising antibody response to prevent the virus from infecting human cells.

Celltrion is also working to increase its manufacturing capabilities to meet the current global and domestic demand for the anti-COVID-19 monoclonal antibody treatment candidate, ensuring potential delivery for as many as 2 million people per year globally.

About CT-P59 (Regdanvimab)

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 including the mutated G-variant strain (D614G variant). In pre-clinical data the treatment candidate demonstrated a 100-fold reduction in viral load of SARS-CoV-2, as well as a reduction in lung inflammation.³
