mRNA technology helped propel the development of some of the most successful drugs in pharma history — notably, the Comirnaty COVID-19 from Pfizer generated almost $56 billion in 2022 while Moderna’s Spikevax vaccine raked in $18.4 billion. But with demand for COVID-19 vaccines cooling, drug developers are aiming to extend the dominion of mRNA technology to flu vaccines. This month, Moderna and the CureVac/GSK alliance announced promising interim results for their respective flu vaccine candidates. Meanwhile, a year ago, in September 2022, Pfizer announced a phase 3 study for its mRNA-based influenza vaccine. NIH is also developing an mRNA vaccine that promises to provide protection against all known influenza subtypes. A phase 1 study of it is underway.

CureVac reports positive outcomes for COVID-19 and flu mRNA vaccines in seniors

The biopharma CureVac (Nasdaq:CVAC) and its partner GSK (NYSE:GSK) have announced positive extended preliminary data from two Phase 1 mRNA vaccine trials, one involving COVID-19 and another seasonal flu.

The company says the positive data support the next stage of clinical testing for modified mRNA COVID-19 and flu vaccines in 2023.

CureVac, which struggled to gain traction for its first-generation mRNA COVID-19 vaccine, is using a second-generation mRNA backbone for its latest mRNA COVID-19 and flu vaccines.

In early January, CurVac announced positive preliminary data from the Phase 1 clinical programs in COVID-19 and seasonal flu.

In a CureVac call with analysts, Umer Raffat, senior managing director at Evercore, stated that the data released then were “half-baked,” adding that a lot of more data from the ongoing Phase 1 study was forthcoming.

“This is a Phase 1 with small numbers, but I think the data clearly show the i…

CureVac files lawsuit against BioNTech over patent infringement

The mRNA-focused biopharma CureVac N.V. (Nasdaq:CVAC) has filed a lawsuit in the German Regional Court in Düsseldorf against BioNTech SE (Nasdaq:BNTX) demanding compensation for infringement of CureVac’s patents.

In particular, the lawsuit claims that the four German patents, EP 1 857 122 B1, DE 20 2015 009 961 U1, DE 20 2021 003 575 U1 and DE 20 2015 009 974 U1, were used in the manufacture of the Comirnaty COVID-19 vaccine from BioNTech and Pfizer (NYSE:PFE).

Investors reacted by sending CVAC shares down 1.05% to $14.09. Meanwhile, BNTX shares were up 2.24% to $161.03.

CureVac is not aiming to block the production or distribution of the COVID-19 vaccine.

Over the past year, CureVac has seen its stock valuation plummet after failing to commercialize its first-generation mRNA COVID-19 vaccine.

In June 2021, the company announced that the interim efficacy of the vaccine candidate was 47% in a Phase 2b/3 study.

CureVac is currently par…

CureVac and GSK announce positive preclinical data for bivalent next-gen mRNA vaccine candidate

Tübingen, Germany–based CureVac N.V. (Nasdaq:CVAC) and its partner GSK (NYSE:GSK) have announced positive preclinical data about their second-generation COVID-19 vaccine candidate that combines mRNAs for the beta and delta variants.

The companies conducted the preclinical research in conjunction with the Friedrich-Loeffler-Institut, Germany.

The research pitted the bivalent candidate against monovalent COVID-19 vaccine candidates.

The bivalent vaccine generated a robust immune response in animals, resulting in a significant reduction of viral load, high neutralizing antibody titers and strong T cell responses.

In a test focused on rats, the bivalent vaccine candidate resulted in a two-fold increase in neutralizing antibody titers against the omicron variant compared to the delta variant.

The researchers also tested the vaccine candidate in transgenic mice expressing the human ACE2 receptor.

The companies have published a manuscript o…

CureVac launches Phase 1 study for next-gen mRNA COVID-19 vaccine

CureVac N.V. (Nasdaq:CVAC) and its partner GSK (NYSE:GSK) have launched a Phase 1 dose-escalation study to test the performance of CV2CoV, a COVID-19 vaccine candidate based on CureVac’s second-generation mRNA backbone.

In late morning trading, CureVac’s stock ticked up 0.10% to $19.22.

CVAC shares were trading above $100 before announcing in mid-June 2021 that the interim vaccine efficacy of its first mRNA COVID-19 vaccine candidate was 47% in a Phase 2b/3 study.

Tübingen, Germany–based CureVac believes that its second-generation mRNA could prove to be broadly efficacious against SARS-CoV-2 variants and other pathogens.

Nature published a preclinical study involving cynomolgus macaques last year, indicating that the immunogenicity of CV2CoV was superior to its first-generation vaccine candidate, CVnCoV. The paper concluded that CV2CoV was “comparably immunogenic to the BNT162b2 (Pfizer) vaccine in macaques.”

The dose of the CV2CoV vaccine…

CueVac and GSK launch Phase 1 trial of mRNA-based flu vaccine

CureVac (NSDQ:CVAC) and GSK (NYSE:GSK) have announced the dosing of the first participant in a Phase 1 study of a multivalent influenza vaccine built on a second-generation mRNA backbone. The study is based in Panama and will enroll approximately 240 subjects.

CVAC shares increased 2.27% to $19.34 in mid-day trading.

At various points last year, however, the company’s stock was trading over $100 per share on enthusiasm about the company’s first-generation COVID-19 vaccine. However, the shares later tanked after the company announced that interim vaccine efficacy was 47% in the Phase 2b/3 study.

The company’s second-generation COVID-19 vaccine remains in pre-clinical development.

Its influenza vaccine candidate has multiple non-chemically modified mRNA constructs related to four different influenza strains.

Pfizer (NYSE:PFE) and Moderna (NSDQ:MRNA) are also developing mRNA-based influenza vaccines.

Investors were dis…

Bayer abandons plans to produce first-generation CureVac vaccine

Bayer (ETR:BAYN) had planned to retool a facility in Wuppertal, Germany, to produce CureVac’s (NSDQ:CVAC) COVID-19 vaccine. But Leverkusen, Germany–headquartered Bayer has put those plans on ice, according to the German paper Leverkusener Anzeiger.

Bayer had planned on producing 160 million doses of the vaccine annually.

In June, CureVac reported that its COVID-19 vaccine was 48% efficacious in an international Phase 2b/3 study focused on various age groups. Despite having lower efficacy than the mRNA vaccines from rivals Moderna and Pfizer/BioNTech, CureVac had assumed in July that it would receive marketing authorization to distribute the vaccine in Europe.

The company announced it would withdraw its first-generation vaccine candidate, CVnCoV, from regulatory review at the European Medicines Agency. CureVac also canceled an existing advanced purchase agreement with the European Commission related to the CVnCoV vaccine.

Earlier this week, CureVac…

A couple of years ago, mRNA vaccines remained at the research stage. Now, they are among the best-selling pharmaceutical products with Pfizer (NYSE:PFE), BioNTech (NSDQ:BNTX) and Moderna (NSDQ:MRNA) dominating the market.

That could change in the long run, however, as a growing number of companies develop next generation mRNA COVID-19 vaccines, which promise to be more effective and less likely to cause side effects than their predecessors.

While mRNA COVID-19 vaccines are among the most effective vaccines against the novel coronavirus, researchers have linked their use to rare side effects such as myocarditis.

Future mRNA may be better tolerated. mRNA itself promotes an immune response future mRNA vaccines could optimize reactogenicity through refining the dose or structure of the single-stranded RNA molecule.

Such next-gen vaccines will also likel…

CureVac aims to rebound after announcing disappointing COVID-19 results

Some two week after announcing that its COVID-19 vaccine had an interim efficacy of 47% in a Phase 2b/3 trial, CureVac (NSDQ:CVAC) appears to be regaining its footing.

While its stock is trading well below its Feb. 5 peak of $120.43, CVAC shares have risen 30% in the past five days to $75.95 in mid-day trading today.

The company is installing a new chief operating officer, Dr. Malte Greune, who will begin work on July 1, 2021.

Greune will work to bolster CureVac’s board and clinical and manufacturing capabilities.

Greune joins CureVac from Sanofi where he worked in an executive business development role. Gruene has held various leadership positions at pharma companies in the past decade.

Earlier this month, CureVac cofounder Ingmar Hoerr withdrew his candidacy for nomination to the company’s board. Hoerr also served as the company’s CEO from March to August 2020

CureVac has also charged another co-founder, Florian von der…

CureVac marches on after announced disappointing study results

After CureVac (NSDQ:CVAC) revealed that its first-generation vaccine candidate has an interim efficacy of 47% in a pivotal trial, its stock lost about half its value. The company, however, is undeterred.

Speaking in a call with investors and analysts, CureVac CEO Franz-Werner Haas said the company would continue to seek the authorization of its CVnCoV vaccine and continue developing its next-generation CV2CoV vaccine.

One difference between the vaccine from CureVac and those from Moderna and Pfizer-BioNTech lies in the dose of mRNA. The CureVac vaccine contains 12 µg of mRNA per dose. The Pfizer-BioNTech vaccine uses 30 µg per shot, while the Moderna vaccine contains 100 µg.

Haas, however, stressed the role of virus variants in the 47% interim efficacy figure. The Phase 2b/3 study “provides important insights into a dramatically transformed variant environment, suggesting that we are virtually fighting a different virus — a different pandemic” than six m…

CureVac’s interim vaccine efficacy is 47% in Phase 2b/3 study

Germany-based CureVac (NSDQ:CVAC) announced that its mRNA vaccine was 47% effective against COVID-19 in a second interim analysis of a pivotal study involving approximately 40,000 participants in 10 countries.

The rise of COVID-19 variants played a role in the disappointing results. At least 13 COVID-19 variants were present in the study population who contracted the novel coronavirus. Some 57% of cases involved variants of concern.

FDA generally requires that a vaccine be at least 50% effective in a placebo-controlled trial to win emergency use authorization.
