Moderna Announces Publication in The New England Journal of Medicine of Interim Results From Older Adult Age Cohorts in Phase 1 Study of its mRNA Vaccine Against COVID-19 (mRNA-1273)

Published

 on

mRNA-1273 induced consistently high levels of pseudovirus neutralization antibody titers in all participants in the 56-70 (n=10) and 71+ (n=10) age cohorts

Potent neturalization responses were confirmed by 3 different live virus assays

mRNA-1273 elicited Th1-biased CD4 T cell responses in the 56-70 and 71+ age cohorts

Neutralizing antibody titers and T cell responses in the 56-70 and 71+ age cohorts were consistent with those reported in younger adults

At the 25 µg and 100 µg dose levels, mRNA-1273 was generally well-tolerated in all age cohorts

Moderna, Inc., (Nasdaq: MRNA) a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines to create a new generation of transformative medicines for patients, today announced the publication of the second interim analysis of the open-label Phase 1 study of mRNA-1273, its vaccine candidate against COVID-19, in The New England Journal of Medicine . This interim analysis evaluated a two-dose vaccination schedule of mRNA-1273 given 28 days apart in 40 healthy adult participants across two dose levels (25 and 100 µg) in two age cohorts (ages 56-70 and ages 71+), and reports results through Day 57 (1 month after the second dose). This analysis found that both the 25 µg and 100 µg dose levels were generally well-tolerated in both age cohorts. Immune responses were dose-dependent with the 100 µg dose eliciting higher binding and neutralizing antibody titers, supporting the selection of the 100 µg dose for further study in the Phase 3 trial. The study was led by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

“These interim Phase 1 data suggests that mRNA-1273, our vaccine candidate for the prevention of COVID-19, can generate neutralizing antibodies in older and elderly adults at levels comparable to those in younger adults,” said Tal Zaks, M.D., Ph.D., Chief Medical Officer of Moderna. “Given the increased morbidity and mortality of COVID-19 in older and elderly adults, these data give us optimism in demonstrating mRNA-1273’s protection in this population, which is being evaluated in the Phase 3 COVE study.”

Both the 25 µg and 100 µg dose levels of mRNA-1273 were generally well-tolerated, with no serious adverse events reported through Day 57. The most common solicited adverse events were headache, fatigue, myalgia, chills, and pain at the injection site, the majority of which were mild-to-moderate in severity and of self-limited duration. Local and systemic reactogenicity were more common and more frequently moderate in severity after the second dose. Two severe solicited systemic adverse events occurred following the second vaccination: fever in one participant in the ages 56-70 cohort who received the 25 µg dose and fatigue in one participant in the ages 71+ cohort who received the 100 µg dose. Clinical laboratory values of Grade 2 or higher revealed no pattern of concern. Participants will continue to be followed through 13-months to allow for a longer assessment of vaccine-related adverse events.

At both the 25 µg and 100 µg dose levels, after two vaccinations, mRNA-1273 induced dose-dependent binding antibody responses reaching the upper quartile of the distribution of convalescent sera. At Day 57 (1 month post-dose 2), geometric mean titers (GMT) exceeded the median of those seen in convalescent sera from 41 individuals with confirmed COVID-19 diagnosis.

Neutralizing activity was assessed with multiple assays, including a pseudovirus neutralization assay (pseudotyped lentivirus reporter single-round-of-infection neutralization assay [PsVNA]) against the two most common SARS-CoV-2 variants (614D and 614G) and three live-virus neutralization assays (SARS-CoV-2 nanoluciferase high-throughput neutralization assay [nLUC HTNA], focus reduction neutralization test mNeonGreen [FRNT-mNG] and classical plaque-reduction neutralization test [PRNT]). No participants had detectable neutralizing responses by any assay prior to vaccination, and robust neutralizing activity was observed in all participants 14 days after the second vaccination.

Psuedovirus neutralization responses were observed as early as seven days after the second vaccination and were dose-dependent across all age groups (18-55, 56-70 and 71+). At Day 43 at the 100 µg dose level, PsVNA ID 50 titers in the older adult cohorts ages 56-70 (GMT 402) and 71+ (GMT 317) were comparable to those seen in the age 18-55 cohort (GMT 360), and 3- to 4-fold higher than those seen in convalescent sera (GMT 106). Titers remained high through four weeks after the second dose in all age cohorts. Neutralizing activity against the 614G variant was also observed at the 100 µg dose in all age cohorts.

Results were consistent using 3 live virus assays. Neutralizing antibody titers as measured by nLUC HTNA and FRNT-mNG were similar across all age groups (18-55, 56-70 and 71+). At Day 43, PRNT 80 GMT in the 100 ug dose groups was 878 in the 56-70 and 317 in the 71+ age cohort, representing 5.5 and 2.0-fold above convalescent sera respectively, and 4.1-fold above convalescent sera in the 18-55 age group (GMT 654).

The 25 µg dose in the 56-70 age cohort and the 100 µg dose level across all age groups (18-55, 56-70 and 71+) elicited a strong Th1-biased CD4 T cell response.

The U.S. government has purchased 100 million doses of mRNA-1273, with an option to purchase an additional 400 million doses.

About mRNA-1273

mRNA-1273 is an mRNA vaccine against COVID-19 encoding for a prefusion stabilized form of the Spike (S) protein, which was co-developed by Moderna and investigators from the National Institute of Allergy and Infectious Disease’s (NIAID) Vaccine Research Center. The first clinical batch, which was funded by the Coalition for Epidemic Preparedness Innovations, was completed on February 7, 2020 and underwent analytical testing; it was shipped to the National Institutes of Health (NIH) on February 24, 42 days from sequence selection. The first participant in the NIAID-led Phase 1 study of mRNA-1273 was dosed on March 16, 63 days from sequence selection to Phase 1 study dosing. On May 12, the FDA granted mRNA-1273 Fast Track designation. On May 29, the first participants in each age cohort: healthy adults ages 18-55 years (n=300) and older adults ages 55 years and above (n=300) were dosed in the Phase 2 study of mRNA-1273. On July 8, the Phase 2 study completed enrollment.

The Phase 3 COVE study of mRNA-1273, being conducted in collaboration with the NIH and BARDA, began on July 27. Results from a non-human primate preclinical viral challenge study evaluating mRNA-1273 were recently published in The New England Journal of Medicine. On July 14, an interim analysis of the original cohorts in the NIH-led Phase 1 study of mRNA-1273 was published in The New England Journal of Medicine . A summary of the company’s work to date on COVID-19 can be found here .

The Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS), is supporting the continued research and development of mRNA-1273 with $955 million in federal funding under Contract no. 75A50120C00034. BARDA is reimbursing Moderna for 100 percent of the allowable costs incurred by the company for conducting the program described in the BARDA contract. The U.S. government has committed $1.525 billion to purchase supply of mRNA-1273 under U.S. Department of Defense Contract No. W911QY-20-C-0100.

About Moderna’s Prophylactic Vaccines Modality

Moderna scientists designed the company’s prophylactic vaccines modality to prevent infectious diseases. More than 1,900 participants, prior to enrolling the Phase 3 study of mRNA-1273, have been enrolled in Moderna’s infectious disease vaccine clinical studies under health authorities in the U.S., Europe and Australia. Clinical data demonstrate that Moderna’s proprietary vaccine technology has been generally well-tolerated and can elicit durable immune responses to viral antigens. Based on clinical experience across Phase 1 studies, the company designated prophylactic vaccines a core modality and is working to accelerate the development of its vaccine pipeline.

The potential advantages of an mRNA approach to prophylactic vaccines include the ability to combine multiple mRNAs into a single vaccine, rapid discovery to respond to emerging pandemic threats and manufacturing agility derived from the platform nature of mRNA vaccine design and production. Moderna has built a fully integrated manufacturing plant which enables the promise of the technology platform.

Moderna currently has nine development candidates in its prophylactic vaccines modality, including:

Vaccines against respiratory infections

  • Respiratory syncytial virus (RSV) vaccine for older adults (mRNA-1777 and mRNA-1172 or V172 with Merck)
  • RSV vaccine for young children (mRNA-1345)
  • Human metapneumovirus (hMPV) and parainfluenza virus type 3 (PIV3) vaccine (mRNA-1653)
  • COVID-19 vaccine (mRNA-1273)
  • Influenza H7N9 vaccine (mRNA-1851)

Vaccines against infections transmitted from mother to baby

  • Cytomegalovirus (CMV) vaccine (mRNA-1647)
  • Zika vaccine (mRNA-1893 with BARDA)

Vaccines against highly prevalent viral infections

  • Epstein-Barr virus (EBV) vaccine (mRNA-1189)

To date, Moderna has demonstrated positive Phase 1 data readouts for eight prophylactic vaccines (H10N8, H7N9, RSV, chikungunya virus, hMPV/PIV3, CMV, Zika and COVID-19). Moderna’s CMV vaccine is currently in a Phase 2 dose-confirmation study. Moderna’s investigational Zika vaccine (mRNA-1893), currently in a Phase 1 study, was granted FDA Fast Track designation in August 2019.

Manitoba piloting rapid COVID-19 testing for healthcare workers – CTV News Winnipeg

Published

 on


Public health officials in Manitoba are piloting a project to help reassure health care workers that they are safe when coming to work.

Lanette Siragusa, the chief nursing officer with Shared Health, revealed on Wednesday that public health is piloting a rapid COVID-19 testing pattern for healthcare workers.

“As of last week at the Health Sciences Centre, 150 symptomatic health care workers were tested,” Siragusa said, noting 146 of the workers tested negative for COVID-19, and were cleared to work.

Four of the staff members tested positive, and are now self-isolating.

The goal of the pilot project is to see if hospitals will be able to identify positive tests among staff earlier and help potentially reduce the spread of COVID-19 in health care facilities.

Siragusa said the rapid testing is also not a substitute for wearing approved personal protective equipment while working.

She added rapid testing could become important in the coming months.

“(Rapid testing) could prove to be an important tool as we approach the respiratory virus season, when many health care workers may have one or more influenza-like illness symptoms, but do not have COVID-19,” Siragusa said.

The pilot project is currently being assessed by public health, and Siragusa said they will announce more on it in the coming days.

Winnipeg students devastated after COVID restrictions silence school choirs – CBC.ca

Published

 on


Hundreds of students in Winnipeg have been ordered by the provincial government to stop singing — something a choir teacher says was an ill-informed decision impacting the mental health of students.

“I was just so extremely disappointed because I do not believe the decision was based upon solid ground,” said Maples Collegiate choral teacher Dorothy Dyck.

Since Oct. 26, schools in the Winnipeg metropolitan area and northern Manitoba have been under a code orange in the province’s pandemic response system.

One of the new rules is that indoor choir and the use of wind instruments are not permitted.

That decision is affecting 250 students at Maples Collegiate who participate in six choirs, Dyck said.

Dyck said she doesn’t think Manitoba’s health officials knew all the precautions her school has taken.

“We didn’t get any directive from the province at all,” she said. “We had to figure it out, and so we did. We spent all summer reading, and researching, and waiting for these studies to come out,” she said.

In August, two studies, one from the University of Colorado and one from the University of Cincinnati, looked at how aerosols were spread while singing and playing instruments.

“Out of these studies, things were brought forward for keeping singing as safe as possible, and that’s what we were doing,” Dyck said.

Singing with masks on for 30 minutes in the gym

Along with singing in masks, the rehearsal time was also limited to 30 minutes, something the study out of Colorado found dropped the rate of infection from 87 per cent down to just 12.

The Maples choirs also moved to the gymnasium so everyone could spread out in an open space.

Dyck said the school division’s head of maintenance climbed up into the vents of the gym to get information about the ductwork. A math teacher calculated the air ventilation to determine air was being exchanged every five minutes.

We are as safe as any other activity.​​​​​– Dorothy Dyck, Maples Collegiate choral teacher

“No one is saying that we can guarantee that things are completely safe,” Dyck said. “We now can point to those numbers and know that we are as safe as any other activity.”

A spokesperson for the provincial government says its guidelines on music are based on multiple reports globally where participation in a choir was associated with “super-spreader” events, where COVID-19 was spread to many people.

“Infected people may transmit the virus over greater distances through their saliva or respiratory droplets while singing,” the spokesperson wrote.

To date, there have been three confirmed cases of COVID-19 at Maples Collegiate, principal Scott Shier said.

Dyck said the province should take a second look at how schools were running their choirs, rather than just banning them outright.

“They’re kids that are just trying to find their voices,” she said.

She says she worries the pandemic is affecting the mental health of students.

“We see their dead eyes. Their body language: they’re slumped forward, their arms are limp, they don’t really raise their hands when they’re asking questions,” she said.

“We’ve really worked hard at trying to use choir and trying to use singing as breathing life into their bodies and changing their eyes, and we had just started to see some real progress.”

‘Devastated’ at province’s decision

Jashdane Santiago, a Grade 11 student and member of three choirs, said she’s struggling to accept that she can’t sing in choir anymore.

“I was very much devastated,” Santiago said.

“Being in choir feels like you’re flying. But then with the news saying that you can’t sing anymore, it just felt like the wings that I’ve been flying with were just clipped,” she said.

The choirs already can’t perform, so it was an extra blow to have their rehearsals taken away, she said.

“Everyone had really high hopes that we could still do what we would normally do, but just a bit different than before.”

Javen Cabrera, a Grade 12 student, said he didn’t take the news well either.

“It was heartbreaking,” Cabrera said. “I was confused, hurt, and really angry.”

The pair said they would be happy to take any extra precautions if it meant they could keep singing.

“Singing with other people reminds me that I’m not alone,” Cabrera said.

The superintendent for Seven Oaks School Division said the they are in discussions with the province about the new rules.

“We’re trying to make the province aware of some of the measures the teachers have taken. We’re doing everything we can to keep a strong program going,” Brian O’Leary said.
