Anti-SARS-CoV-2 monoclonal antibodies in clinical study

• LY-CoV555 (LY3819253) and combination of LY-CoV555 with LY-CoV016 (LYLY3832479). On June 1, 2020, Eli Lilly and Company announced LY-CoV555 (LY3819253), an anti-SARS-CoV2 IgG1 antibody, has been administered to COVID-19 patients. On October 7, 2020, Lilly announced that they submitted a request to the  U.S. Food and Drug Administration (FDA) for emergency use authorization (EUA) of LY-CoV555, which was granted on November 9, 2020. Documents relating to the EUA can be found here.
  • LY3819253 is a human antibody that targets the SARS-CoV-2 spike protein. It was derived from human B cells from convalescent patients.
  • The NCT04427501 Phase 2 study has 3-arms:  1) LY-CoV555 (LY3819253); 2) combination of LY-CoV555 with LY-CoV016 (LYLY3832479); and 3) placebo. The study will evaluate the efficacy and safety of LY3819253 and LY3832479 in participants with mild to moderate COVID-19 illness
  • The NCT04497987 Phase 3 trial will evaluate the efficacy and safety of LY3819253 in preventing SARS-CoV-2 infection and COVID-19 in skilled nursing and assisted living facility residents and staff. NIAID and Lilly are collaborators in this study.
  • The NCT04501978 Phase 3 trial is a master protocol designed to allow for the study of multiple investigational agents compared to placebo in adults hospitalized with COVID-19. One study arm compared the effects of LY3819253 vs. remdesivir vs placebo in hospitalized patients. The DSMB reviewed data from the trial on Oct. 26, 2020 and recommended no further participants be randomized to receive LY-CoV555 and that the investigators be unblinded to the data. This recommendation was based on a low likelihood that the intervention would be of clinical value in this hospitalized patient population. 
  • The  NCT04518410 Phase 2/3 “Adapt Out COVID” study is an adaptive platform treatment trial for outpatients With COVID-19. NIAID and Lilly are collaborators in this study.

• REGN-COV2 (REGN10933 + REGN10987). On June 11, 2020, Regeneron Pharmaceuticals, Inc. announced the start of the first clinical trial of REGN-COV2 for the prevention and treatment of COVID-19. On October 7, 2020, Regeneron announced that they submitted a request to the  U.S. Food and Drug Administration (FDA) for an EUA for REGN-COV2, which was granted on November 20, 2020.
  • REGN-COV2 is a cocktail of the human antibodies REGN10933 and REGN10987, which were derived from Regeneron’s parallel efforts using both humanized VelocImmune® mice and blood samples from recovered COVID-19 patients to generate a large and diverse collection of antibodies targeting multiple different regions of the receptor-binding domain of the SARS-CoV-2 spike protein. Two papers describing the creation of REGN-COV2 and its anti-viral activity have been accepted for publication in Science.
  • The REGN-COV2 clinical program will consist of four separate study populations: hospitalized COVID-19 patients, non-hospitalized symptomatic COVID-19 patients, uninfected people in groups that are at high-risk of exposure and uninfected people with close exposure to a COVID-19 patient. The placebo-controlled trials will be conducted at multiple sites. The first two adaptive Phase 1/2/3 studies are evaluating REGN-COV2 as a treatment for hospitalized and non-hospitalized patients with COVID-19. The Phase 1 portion will focus on virologic and safety endpoints, and the Phase 2 portion will focus on virologic and clinical endpoints. Data from the Phase 1 and Phase 2 studies will be used to refine the endpoints and determine size for the Phase 3 studies.         

• VIR-7831/GSK4182136. Vir Biotechnology, Inc. and GlaxoSmithKline plc developed VIR-7831, which is a human anti-SARS-CoV-2 antibody.
  • The Phase 2/3 study will assess VIR-7831 for the early treatment of COVID-19 in patients who are at high risk of hospitalization. 
  • The NCT04501978 Phase 3 trial is a master protocol designed to allow for the study of multiple investigational agents compared to placebo in adults hospitalized with COVID-19.  A study arm will include VIR-7831.                                                                      

• CT-P59. On July 17, 2020, Celltrion announced the start of a Phase 1 study of CT-P59.

The study will evaluate the safety of the antiviral antibody treatment candidate in healthy participants who have not been diagnosed with COVID-19. The trial’s completion is expected by Q3 of this year.
  • A Phase 2/3 study investigating CT-P59  as a COVID-19 preventative measure was initiated in late September 2020. 
  • On December 29, 2020, Celltrion announced that they had submitted an application for conditional marketing authorisation of CT-P59 to the Korean Ministry of Food and Drug Safety.
  • On February 5, 2021, South Korea granted conditional approval.

• AZD7442 (AZD8895 + AZD1061). AstraZeneca licensed coronavirus-neutralizing antibodies from Vanderbilt University, and advanced two (AZD8895 and AZD1061) into clinical development as a potential combination therapy (AZD7442) for the prevention and treatment of COVID-19.
  • NCT04507256 is a Phase 1 double-blind, placebo-controlled study to evaluate the safety, tolerability and pharmacokinetics of AZD7442 in healthy adults.

The antibody was identified by screening B cells from convalescent COVID-19 patients, and engineered to introduce LALA mutations to silence the Fc portion. JS016 was shown to provide protection from SARS-CoV-2 infection when administered to rhesus monkeys (Shi et al. Nature 2020).
  • The Phase 1 clinical study will evaluate the tolerability, safety, pharmacokinetics and immunogenicity of JS016 in healthy volunteers.

• BRII-96, BRII-98. Brii Biosciences initiated clinical studies of 2 human anti-SARS-CoV-2 antibodies in mid-July 2020.
  • The Phase 1 studies are randomized, single-blind, placebo-controlled, single ascending dose escalation studies of the safety, tolerability, and pharmacokinetics of the antibodies administered intravenously to healthy adult volunteers.
  • The NCT04501978 Phase 3 trial is a master protocol designed to allow for the study of multiple investigational agents compared to placebo in adults hospitalized with COVID-19.  Study arms will include BRII-96 and BRII-98.
