Coronavirus treatment: Vaccines and drugs in the pipeline for COVID-19

As of April-2020, There are 5 vaccine candidates and 21 drug candidates are under the clinical stage of development

There are more than 70 drug candidate under pre-clinical stage of development

Coronavirus disease 2019 (COVID-19) is caused by a novel coronavirus which is named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; formerly called 2019-nCoV).

  • It was first identified amid an outbreak of respiratory illness cases in Wuhan City, Hubei Province, China.
  • The WHO declared the COVID-19 outbreak a global health emergency on On January 30, 2020. On March 11, 2020, It was declared as a global pandemic by WHO
  • It is noted that its first such designation since declaring H1N1 influenza a pandemic in 2009.

There is no drug, biologicals, vaccines approved for the treatment of COVID19. The following categories of drugs are under development:

  • Antiviral
  • Anti Inflammatory
  • Plasma therapy
  • Vaccines

Kaletra:

  • It was tested by AbbVie’s for COVID19. It is a combination of lopinavir and ritonavir. Lopinavir is an inhibitor of the HIV protease.
  • Ritonavir inhibits the CYP3A-mediated metabolism of lopinavir, thereby providing increased plasma levels of lopinavir.
  • Kaletra failed across the board in a 199-patient clinical trial. It didn’t a top standard of care at improving clinical symptoms, extending lifespan or cutting viral shedding in patients hospitalized with severe COVID-19, results from a study published Wednesday in The New England Journal of Medicine show”

Actemra:

  • It is a brand name for Tocilizumab. It is being tested by Roche for COVID19

    Mechanism of action:
  • “Tocilizumab binds to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R), and has been shown to inhibit IL-6-mediated signalling through these receptors.
  • IL-6 is a pleiotropic pro-inflammatory cytokine produced by a variety of cell types including T- and B-cells, lymphocytes, monocytes and fibroblasts.
  • IL-6 has been shown to be involved in diverse physiological processes such as T-cell activation, induction of immunoglobulin secretion, initiation of hepatic acute-phase protein synthesis, and stimulation of hematopoietic precursor cell proliferation and differentiation.
  • IL-6 is also produced by synovial and endothelial cells leading to local production of IL-6 in joints affected by inflammatory processes such as rheumatoid arthritis.”

As of 19th Mar-2020, Roche announced that “we are working with the Food & Drug Administration (FDA) to initiate a randomised, double-blind, placebo-controlled Phase III clinical trial in collaboration with the Biomedical Advanced Research and Development Authority (BARDA), a part of the US Health and Human Services Office of the Assistant Secretary for Preparedness and Response (ASPR), to evaluate the safety and efficacy of Actemra®/RoActemra® (tocilizumab) plus standard of care in hospitalised adult patients with severe COVID-19 pneumonia compared to placebo plus standard of care”

Lenzilumab:

 It is being tested by Humanigen for COVID19. FDA Approved initiation of Humanigen’s Phase III Study of Lenzilumab in COVID-19 Patients.

It is multi-center, randomized, placebo-controlled, double-blinded Phase III study enrollment to focus on adult, hospitalized patients with COVID-19 pneumonia and at high risk of progression to respiratory failure.
https://clinicaltrials.gov/ct2/show/NCT04351152?intr=Lenzilumab&draw=2&rank=2

Mechanism of action:
“A recombinant monoclonal antibody against the cytokine granulocyte macrophage colony-stimulating factor (GM-CSF), with potential immunomodulating activity. Upon administration, lenzilumab binds to and neutralizes GM-CSF.

This prevents GM-CSF binding to the GM-CSF receptor, which is a heterodimeric protein expressed on myeloid progenitor cells, and prevents GM-CSF-mediated signaling.

This may induce apoptosis in and inhibit proliferation of cancer cells that overproduce GM-CSF. GM-CSF plays a key role in the differentiation and proliferation of monocytes, macrophages and granulocytes; elevated levels of GM-CSF are associated with certain autoimmune diseases, inflammatory diseases, and cancers”

https://www.cancer.gov/publications/dictionaries/cancer-drug/def/lenzilumab

CD24Fc:

  • It is being tested by Oncoimmune for COVID19
    Mechanism of action: 
    “CD24Fc has a dual mechanism of action:
  • First, CD24Fc binds DAMPs, trapping the inflammatory stimuli to prevent their interaction with TLR receptors
  • Second, CD24Fc binds Siglec G/10 and regulates host response to tissue injuries Siglec G/10-associated SHP1 inhibitory signalling
  • Both mechanisms likely act in concert to modulate immune responses.” http://www.oncoimmune.com/product-development/

Registered study: Phase III study registered with USFDA.

Study objective:
“The study is designed as a randomized, placebo-controlled, double blind, multicenter, Phase III trial to compare two COVID-19 treatment regimens in hospitalized adult subjects who are diagnosed with severe COVID 19.”
https://clinicaltrials.gov/ct2/show/NCT04317040?intr=CD24Fc&draw=2&rank=2

Prezcobix:

Shanghai Public health clinical centre is developing this drug for COVID19.
PREZCOBIX is a fixed-dose combination product containing 800 mg of darunavir and 150 mg of cobicistat.

“Darunavir, a HIV protease inhibitor, prevents HIV replication through binding to the enzyme, stopping the dimerization and the catalytic activity of HIV-1 protease. In particular, it inhibits the cleavage of HIV encoded Gag-Pol proteins.

  • Mechanism of Action:
  • cobicistat acts as a pharmacokinetic enhancer by inhibiting cytochrome P450 3A isoforms (CYP3A) and therefore increases the systemic exposure of coadministered agents that are metabolized by CYP3A enzymes”
  • It is an interventional randomized Phase III study to evaluate the efficacy and safety of Darunavir and Cobicistat for Treatment of COVID-19 (DC-COVID-19) https://clinicaltrials.gov/ct2/show/NCT04252274

Colchicine: 

On 8-April-2020, it was announced that “The Montreal Heart Institute (MHI) Research Centre has collaborated with New York City’s NYU Grossman School of Medicine for a new COVID-19 clinical study.

The clinical study, dubbed COLCORONA, will assess whether colchicine will serve as an effective treatment to prevent the phenomenon of major inflammatory storm present in adults suffering from severe complications related to COVID-19.”

  • COLCORONA trial will enrol around 6,000 participants who will be followed for 30 days and initial results will be revealed a few days upon the completion of a study.”

    Study Description:
  • This is a phase 3, multi-center, randomized, double-blind, placebo-controlled multicenter study to evaluate the efficacy and safety of colchicine in adult patients diagnosed with COVID-19 infection and have at least one high-risk criterion.

Kevzara:

https://www.sanofi.com/en/media-room/press-releases/2020/2020-03-30-07-00-00

  • About the Trial:
  • This Phase 2/3, randomized, double-blind, placebo-controlled trial uses an adaptive design to evaluate the safety and efficacy of Kevzara in adults hospitalized with serious complications from COVID-19.
  • To enter the trial, patients must have pneumonia and be hospitalized with laboratory-confirmed COVID-19 that is classified as severe or critical, or who are suffering from multi-organ dysfunction. After receiving the study dose, patients will be assessed for 60 days, or until hospital discharge or death.
  • In the Phase 2 part of the trial, patients will be randomized 2:2:1 into three groups: Kevzara higher dose, Kevzara lower dose and placebo.

    The Phase 2 findings will be utilized in an adaptive manner to determine transition into Phase 3, helping to determine the endpoints, patient numbers and doses.
  • If the trial continues with all three treatment arms to the end, it is expected to enroll approximately 300 patients, depending on the status of the COVID-19 outbreak and the proportion of patients with severe COVID-19.” https://clinicaltrials.gov/ct2/show/NCT04315298

Hydroxychloroquine:

 On 17-Mar 2020, the University of Minnesota announced to launch a clinical trial on a post-exposure treatment for coronavirus COVID-19 disease.
