Coronavirus (COVID-19) Update: FDA Authorizes Drug Combination for Treatment of COVID-19 (11/19/2020) | FDA
…an emergency use authorization (EUA) for the drug baricitinib, in combination with remdesivir, for the treatment of suspected or laboratory confirmed COVID-19 in hospitalized adults and pediatric patients two years of age or older requiring supplemental oxygen, invasive mechanical ventilation, or extracorporeal membrane oxygenation (ECMO).
… Baricitinib is not authorized or approved as a stand-alone treatment for COVID-19. …
Baricitinib is a janus kinase inhibitor, which blocks the activity of one or more of a specific family of enzymes, interfering with the pathway that leads to inflammation. Baricitinib is a prescription oral tablet medication that is FDA-approved (and sold under the brand name Olumiant) for the treatment of moderately to severely active rheumatoid arthritis. …
Remdesivir is an FDA-approved (and sold under the brand name Veklury) intravenous antiviral drug for use in adult and pediatric patients 12 years of age and older and weighing at least 40 kilograms (about 88 pounds) for the treatment of COVID-19 requiring hospitalization. Remdesivir also remains authorized for emergency use for the treatment of suspected or laboratory-confirmed COVID-19 in hospitalized pediatric patients weighing 3.5 kg (about 7.7 pounds) to less than 40 kg or hospitalized pediatric patients less than 12 years of age weighing at least 3.5 kg. …
… Possible side effects of baricitinib in combination with remdesivir include serious infections, blood clots, changes in certain lab test results and allergic reactions.
The EUA was issued to Eli Lilly and Company. …

Antiviral Drugs That Are Approved or Under Evaluation for the Treatment of COVID-19 (11/03/2020) | NIH

Ivermectin

The Latest Research on COVID-19 Treatments and Medications in the Pipeline (11/18/2020) | @GoodRx
… Remdesivir is also being studied in combination with other medications. Early results reported that hospitalized COVID-19 patients who got both remdesivir and baricitinib (Olumiant) recovered about 1 day faster than those who only got remdesivir. Additionally, patients had a 30% higher chance of clinical improvement at day 15 when taking both medications together. The full data has not been shared yet.
Not all remdesivir studies have been promising. On October 15, 2020, a large, randomized study from the World Health Organization (WHO) found that remdesivir had little or no effect on death rate in hospitalized patients with COVID-19. The death rate was about 11% regardless of whether patients got remdesivir or not. These results have not been peer-reviewed yet. …

… “The … panel found a lack of evidence that remdesivir improved outcomes that matter to patients such as reduced mortality, need for mechanical ventilation, time to clinical improvement, and others,” the guideline said. …
At the end of October, Gilead cut its 2020 revenue forecast, citing lower-than-expected demand and difficulty in predicting sales of remdesivir, which is also known as Veklury.

Experimental drug given to Trump to treat covid-19 wins FDA clearance: But Regeneron’s antibody treatment is expected to be in short supply. (11/21/2020) | @washingtonpost
… The drug, made by Regeneron Pharmaceuticals, is designed to prevent infected people from developing severe illness. Instead of waiting for the body to develop its own protective immune response, the drug imitates the body’s natural defenses. It is the second drug of this type — called a monoclonal antibody — to be cleared for treating covid-19. The FDA authorized Eli Lilly & Co.’s drug on Nov. 9.
Regeneron’s drug is a cocktail of two monoclonal antibodies, called casirivimab and imdevimab. The FDA said in authorizing the cocktail that it may be effective in treating mild to moderate covid-19 in adults and children 12 or older, and is indicated for those at high risk of developing severe illness. Doctors hope the drugs will keep those patients from being hospitalized.
But as with the Lilly treatment, the Regeneron drug is a biological product that is complicated and time-consuming to make…
In a study published Oct. 28 in the New England Journal of Medicine, researchers said the Lilly cocktail lowered the risk of follow-up medical visits and reduced levels of virus in people with mild to moderate symptoms of covid-19. …
Through Operation Warp Speed, the Trump administration effort to speed up treatments and vaccines, the government has bought 300,000 doses each from Lilly and Regeneron at a cost of about $1,250 and $1,500 per dose, respectively, with an option to buy hundreds of thousands more. But that comes as the nation is approaching 200,000 new coronavirus cases each day.
In a sign of how quickly the supply could be used up as the pandemic surges across the country, 40 percent of the doses of Lilly’s bamlanivimab has already been allocated to states. …

Rheumatoid arthritis drug appears to help Covid patients in ICU: Trial suggests that tocilizumab improves outcomes for critically ill patients, say researchers (19/11/2020) | @guardian

…if confirmed by more trial data, the drug will be on track to become only the second effective therapy for the sickest Covid patients, following positive results for the steroid dexamethasone earlier this year. …
Dexamethasone, which costs about £5 per dose, was found in trials to cut the risk of death by a third for patients on ventilators. It is now part of standard care for Covid patients in hospital.
Tocilizumab costs between £500 and £1000 depending on whether patients receive one or two doses. …

Efficacy and safety of tocilizumab in COVID-19 patients: A living systematic review and meta-analysis (w PDF; 11/05/2020) | @CMIJournal
Conclusion
Cumulative moderate certainty evidence shows that tocilizumab reduces the risk of mechanical ventilation in hospitalized COVID-19 patients. While RCTs showed that tocilizumab did not reduce short-term mortality, low certainty evidence from cohort studies suggests an association between tocilizumab and lower mortality. We did not observe a higher risk of infections or adverse events with tocilizumab use. This review will continuously evaluate the role of tocilizumab in COVID-19 treatment.

Efficacy of Tocilizumab on Patients With COVID-19 (08/24/2020) | @MGHMedicine,@genentech ClinicalTrials.gov @nlm_news
Brief Summary:
This is a randomized, double blind, multi-center study to evaluate the effects of tocilizumab compared to placebo on patient outcomes in participants with confirmed SARS-CoV-2 infection and evidence of systemic inflammation.
The aim of this study is to test the effect of Tocilizumab on multi-organ dysfunction in a phase 3 randomized controlled trial among hospitalized patients with COVID-19 infection.
Specifically, as compared to placebo, we will test whether tocilizumab is associated with a reduction in multi-organ dysfunction among hospitalized COVID-19 adult patients with elevated inflammatory measures. Multi-organ dysfunction will be measured as the incidence of the following composite endpoint (mechanical ventilation, renal replacement therapy, mechanical support, need for inotropes or vasopressors, liver dysfunction (increased bilirubin), and all-cause mortality). We will also assess multiple pre-specified secondary (exploratory) endpoints and safety endpoints.
We hypothesize that, as compared to placebo, tocilizumab will reduce transfer to the ICU, need for mechanical ventilation, increase rates of hospital discharge in patients diagnosed with severe COVID-19 infection and evidence of exaggerated inflammatory response.

The FDA has authorized convalescent plasma treatment for coronavirus patients – but some scientists worry it’s too soon (08/26/2020) | @businessinsider
During the 1918 Spanish flu pandemic, doctors discovered they could treat sick patients with the blood of those who had already recovered. …
Antibodies develop in plasma, the liquid portion of blood – they’re part of our body’s natural response to a foreign pathogen. So the idea behind the treatment is to help sick people mount an antibody response to the virus by transferring plasma intravenously from those who already have antibodies.
“What we really need are drugs that, when given early, can prevent a symptomatic person from requiring hospitalization or very dramatically diminish the time that they’re symptomatic,” …
… Plasma must be transferred quickly from a donor to a recipient – and both must have compatible blood types. The quantity is also limited, since it depends on blood donations. …
A national study of 35,000 hospitalized coronavirus patients, which is still awaiting peer review, found that patients less than 80 years old who weren’t on a respirator and received plasma containing high levels of antibodies within three days of their diagnosis had a 35% lower mortality rate than those who were treated four or more days after their diagnosis.
The process of creating hyperimmune globulin involves pooling plasma from recovered patients and heat-treating it so that any remaining pathogens get destroyed. The result is a vial of medicine with consistent antibody levels that can easily be administered to patients. The drug focuses on the most common antibody found in blood ? immunoglobulin G (IgG) – which usually confers long-term immunity.

Because it’s a biological product, it can’t be patented or sold for a profit. As a result, no single research group or company has funded a large, randomized controlled trial of plasma, the highest standard of clinical evidence. …
It isn’t cheap: Between 2012 and 2018, the median cost of bringing a drug to market was $985 million, about $19 million of which goes to clinical research.

Key Facts About Seasonal Flu Vaccine | @CDCgov
FluVaccines_CDC1-table1FluVaccines_CDC2-recommended&viruses
Flu Vaccination
How do flu vaccines work?
Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are used to make the vaccine.
The seasonal flu vaccine protects against the influenza viruses that research indicates will be most common during the upcoming season. Most flu vaccines in the United States protect against four different flu viruses (“quadrivalent”); an influenza A (H1N1) virus, an influenza A (H3N2) virus, and two influenza B viruses. There are also some flu vaccines that protect against three different flu viruses (“trivalent”); an influenza A (H1N1) virus, an influenza A (H3N2) virus, and one influenza B virus. Two of the trivalent vaccines are designed specifically for people 65 and older to create a stronger immune response.
What kinds of flu vaccines are available?
CDC recommends use of any licensed, age-appropriate influenza vaccine during the 2020-2021 influenza season, including inactivated influenza vaccine [IIV], recombinant influenza vaccine [RIV], or live attenuated influenza vaccine (LAIV). No preference is expressed for any influenza vaccine over another. Both trivalent (three-ingredient) and quadrivalent (four-ingredient) influenza vaccines will be available.
Quadrivalent flu vaccines include:
Standard-dose quadrivalent influenza shots that are manufactured using virus grown in eggs. These include Afluria Quadrivalent, Fluarix Quadrivalent, FluLaval Quadrivalent, and Fluzone Quadrivalent. Different influenza shots are licensed for different age groups. These four vaccines are approved for people 6 months of age and older. Most influenza shots are given in an arm muscle with a needle. One quadrivalent influenza shot (Afluria Quadrivalent) can be given either with a needle (for people aged 6 months and older) or with a jet injector (for people aged 18 through 64 years only). …
Are any of the available flu vaccines recommended over others?
…the Advisory Committee on Immunization Practices (ACIP) recommends…including inactivated influenza vaccine (IIV), recombinant influenza vaccine (RIV), or live attenuated nasal spray influenza vaccine (LAIV4)…
Who Should Not Be Vaccinated?
… Factors that can determine a person’s suitability for vaccination, or vaccination with a particular vaccine, include a person’s age, health (current and past) and any allergies to flu vaccine or its components. …
Flu and COVID-19
Does a flu vaccine increase your risk of getting COVID-19?
Vaccine Effectiveness
Can I get seasonal flu even though I got a flu vaccine this year?
What protection does a flu vaccine provide if I do get sick with flu?
Vaccine Benefits
What are the benefits of flu vaccination?
Vaccine Match
What if circulating viruses and the vaccine viruses are different?
Why is there sometimes not a good match between a vaccine virus and circulating viruses?
Flu viruses are constantly changing (called “antigenic drift”) ? they can change from one season to the next or they can even change within the course of one flu season. Experts must pick which viruses to include in the vaccine many months in advance in order for vaccine to be produced and delivered on time. …
… While all influenza viruses undergo changes when they are grown in eggs, changes in influenza A(H3N2) viruses are more likely to result in antigenic changes compared with changes in other influenza viruses. These so-called “egg-adapted changes” are present in most of the vaccine viruses recommended for use in egg-based vaccine production and may reduce their potential effectiveness against circulating influenza viruses. …
Vaccine Side Effects (What to Expect)
Can a flu vaccine give me flu?
No, a flu vaccine cannot cause flu illness. …
What side effects can occur after getting a flu vaccine?

Flu Vaccine (Flu Shot) | @MedicineNet
Facts you should know about the influenza vaccine (flu shot)
・Types of influenza (flu) vaccines include the injection (killed virus), recombinant (made without flu virus), and nasal spray vaccines (containing live virus). …
What is influenza (flu)?
… Flu is a respiratory infection, that is, an infection that develops primarily in the lungs. People often call respiratory infections caused by other viruses the flu, but this is incorrect. These other infections are usually categorized as URIs (upper respiratory infections) and have multiple causes. …
Influenza viruses are divided scientifically into three types, designated A, B, and C. Influenza types A and B are responsible for epidemics of respiratory illness that occur almost every winter. Influenza type C usually causes either a very mild respiratory illness or no symptoms at all; it does not cause epidemics and does not have the severe public health impact of influenza types A and B. Type A viruses are divided into subtypes and are named based on differences in two viral surface proteins called hemagglutinin (H) and neuraminidase (N). There are 16 known H subtypes and nine known N subtypes. …
The so-called swine flu pandemic of 2009 was caused by a novel influenza A virus designated H1N1 based upon its surface protein types. This virus was originally referred to as swine flu because many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America. However, this virus was actually quite different from the typical swine flu viruses found in pigs.

Types of seasonal influenza vaccine | @WHO_Europe
Two types of influenza vaccine are widely available: inactivated influenza vaccines (IIV) and live attenuated influenza vaccines (LAIV). Traditionally, influenza vaccines (both IIV and LAIV) have been produced to protect against 3 different seasonal influenza viruses (also called trivalent vaccines). In most countries this is still the case and the current trivalent vaccines contain influenza A(H3N2), pandemic A(H1N1) and 1 of 2 influenza B lineage viruses. However, recently vaccines which protect against 4 different viruses, including both influenza B lineage viruses (quadrivalent vaccines), have become available in some countries. …
Annual selection of viruses
The composition of influenza vaccines (both IIV and LAIV) are updated annually by WHO based on information gathered from the Global Influenza Surveillance and Response System (GISRS)…

Flu vaccine | @NHSuk
Flu vaccine and coronavirus (COVID-19)
Flu vaccination is important because:
・if you’re at higher risk from coronavirus, you’re also more at risk of problems from flu
・if you get flu and coronavirus at the same time, research shows you’re more likely to be seriously ill
・it’ll help to reduce pressure on the NHS and social care staff who may be dealing with coronavirus
If you’ve had COVID-19, it’s safe to have the flu vaccine. It’ll be effective at helping to prevent flu.

Treatments that the NIH recommend against using for COVID-19
・Hydroxychloroquine and chloroquine
・Azithromycin … One research group looked at azithromycin in combination with hydroxychloroquine for COVID-19. They reported that 93% of patients cleared the virus after 8 days, but there was no control group so we don’t know if people would have cleared the virus on their own without the medications. There are concerns about potentially serious side effects when using azithromycin and hydroxychloroquine together. The NIH currently recommends against using azithromycin for COVID-19.
・Tocilizumab (Actemra) and other IL-6 inhibitors … By blocking IL-6, tocilizumab helps to calm down the immune system and is believed to also help with managing cytokine storms.
Research on tocilizumab started with a study from France, which reported that people who got tocilizumab were less likely to require ventilation or die. Another study from Italy found that those who got tocilizumab had a lower death rate, though about the same percentage of patients from both groups needed ventilators. On the other hand, tocilizumab did not help COVID-19 patients with early-stage pneumonia. A phase 3 study from the manufacturer also found that tocilizumab did not help for hospitalized COVID-19 patients with severe pneumonia. …
… They showed that patients with severe symptoms who got Kevzara did worse compared to placebo, but patients who had even more severe (critical) symptoms improved compared to placebo. …
