September 1, 2022

Today, the U.S. Food and Drug Administration amended the emergency use authorizations (EUAs) of the Moderna COVID-19 Vaccine and the Pfizer-BioNTech COVID-19 Vaccine to authorize bivalent formulations of the vaccines for use as a single booster dose at least two months following primary or booster vaccination. The bivalent vaccines, which we will also refer to as “updated boosters,” contain two messenger RNA (mRNA) components of SARS-CoV-2 virus, one of the original strain of SARS-CoV-2 and the other one in common between the BA.4 and BA.5 lineages of the omicron variant of SARS-CoV-2.

The Moderna COVID-19 Vaccine, Bivalent, is authorized for use as a single booster dose in individuals 18 years of age and older. The Pfizer-BioNTech COVID-19 Vaccine, Bivalent, is authorized for use as a single booster dose in individuals 12 years of age and older.

The monovalent COVID-19 vaccines that are authorized or approved by the FDA and have been administered to millions of people in the United States since December 2020 contain a component from the original strain of SARS-CoV-2.

What you need to know:

The authorized bivalent COVID-19 vaccines, or updated boosters, include an mRNA component of the original strain to provide an immune response that is broadly protective against COVID-19 and an mRNA component in common between the omicron variant BA.4 and BA.5 lineages to provide better protection against COVID-19 caused by the omicron variant.
The BA.4 and BA.5 lineages of the omicron variant are currently causing most cases of COVID-19 in the U.S. and are predicted to circulate this fall and winter. In June, the agency’s Vaccines and Related Biological Products Advisory Committee voted overwhelmingly to include an omicron component in COVID-19 booster vaccines.
For each bivalent COVID-19 vaccine, the FDA based its decision on the totality of available evidence, including extensive safety and effectiveness data for each of the monovalent mRNA COVID-19 vaccines, safety and immunogenicity data obtained from a clinical study of a bivalent COVID-19 vaccine that contained mRNA from omicron variant BA.1 lineage that is similar to each of the vaccines being authorized, and nonclinical data obtained using a bivalent COVID-19 vaccine that contained mRNA of the original strain and mRNA in common between the BA.4 and BA.5 lineages of the omicron variant.
Based on the data supporting each of these authorizations, the bivalent COVID-19 vaccines are expected to provide increased protection against the currently circulating omicron variant. Individuals who receive a bivalent COVID-19 vaccine may experience side effects commonly reported by individuals who receive authorized or approved monovalent mRNA COVID-19 vaccines.
With today’s authorization, the monovalent mRNA COVID-19 vaccines are not authorized as booster doses for individuals 12 years of age and older.
The agency will work quickly to evaluate future data and submissions to support authorization of bivalent COVID-19 boosters for additional age groups as we receive them.

Who is eligible to receive a single booster dose and when:

Individuals 18 years of age and older are eligible for a single booster dose of the Moderna COVID-19 Vaccine, Bivalent if it has been at least two months since they have completed primary vaccination or have received the most recent booster dose with any authorized or approved monovalent COVID-19 vaccine.
Individuals 12 years of age and older are eligible for a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine, Bivalent if it has been at least two months since they have completed primary vaccination or have received the most recent booster dose with any authorized or approved monovalent COVID-19 vaccine.

“The COVID-19 vaccines, including boosters, continue to save countless lives and prevent the most serious outcomes (hospitalization and death) of COVID-19,” said FDA Commissioner Robert M. Califf, M.D. “As we head into fall and begin to spend more time indoors, we strongly encourage anyone who is eligible to consider receiving a booster dose with a bivalent COVID-19 vaccine to provide better protection against currently circulating variants.”

The Moderna COVID-19 Vaccine, Bivalent and the Pfizer-BioNTech COVID-19 Vaccine, Bivalent contain mRNA from the SARS-CoV-2 virus. The mRNA in these vaccines is a specific piece of genetic material that instructs cells in the body to make the distinctive “spike” protein of the original virus strain and the omicron variant lineages BA.4 and BA.5. The spike proteins of BA.4 and BA.5 are identical.

“The FDA has been planning for the possibility that the composition of the COVID-19 vaccines would need to be modified to address circulating variants. We sought input from our outside experts on the inclusion of an omicron component in COVID-19 boosters to provide better protection against COVID-19. We have worked closely with the vaccine manufacturers to ensure the development of these updated boosters was done safely and efficiently. The FDA has extensive experience with strain changes for annual influenza vaccines. We are confident in the evidence supporting these authorizations,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research. “The public can be assured that a great deal of care has been taken by the FDA to ensure that these bivalent COVID-19 vaccines meet our rigorous safety, effectiveness and manufacturing quality standards for emergency use authorization.”

For each of the bivalent COVID-19 vaccines authorized today, the FDA evaluated immunogenicity and safety data from a clinical study of a booster dose of a bivalent COVID-19 vaccine that contained a component of the original strain of SARS-CoV-2 and a component of omicron lineage BA.1. The FDA considers such data as relevant and supportive of vaccines containing a component of the omicron variant BA.4 and BA.5 lineages. Furthermore, data pertaining to the safety and effectiveness of the current mRNA COVID-19 vaccines, which have been administered to millions of people, including during the omicron waves of COVID-19, contributed to the agency’s evaluation.

Data Supporting the Moderna COVID-19 Vaccine, Bivalent Authorization

To evaluate the effectiveness of a single booster dose of the Moderna COVID-19 Vaccine, Bivalent for individuals 18 years of age and older, the FDA analyzed immune response data among approximately 600 individuals 18 years of age and older who had previously received a two-dose primary series and one booster dose of monovalent Moderna COVID-19 Vaccine. These participants received a second booster dose of either the monovalent Moderna COVID-19 Vaccine or Moderna’s investigational bivalent COVID-19 vaccine (original and omicron BA.1) at least 3 months after the first booster dose. After 28 days, the immune response against BA.1 of the participants who received the bivalent vaccine was better than the immune response of those who had received the monovalent Moderna COVID-19 Vaccine.

The safety of a single booster dose of the Moderna COVID-19 Vaccine, Bivalent for individuals 18 years of age and older is supported by safety data from a clinical study which evaluated a booster dose of Moderna’s investigational bivalent COVID-19 vaccine (original and omicron BA.1), safety data from clinical trials which evaluated primary and booster vaccination with the monovalent Moderna COVID-19 Vaccine, and postmarketing safety data with the monovalent Moderna COVID-19 Vaccine.

The safety data accrued with the bivalent vaccine (original and omicron BA.1) and with the monovalent Moderna COVID-19 Vaccine are relevant to the Moderna COVID-19 Vaccine, Bivalent because these vaccines are manufactured using the same process.

The clinical study that evaluated the safety of a booster dose of the bivalent vaccine (original and omicron BA.1) included approximately 800 participants 18 years of age and older who had previously received a two dose primary series and one booster dose of the monovalent Moderna COVID-19 Vaccine, and then at least 3 months later, received a second booster dose with either the monovalent Moderna COVID-19 Vaccine or Moderna’s investigational bivalent COVID-19 vaccine (original and omicron BA.1).

Among the study participants who received the bivalent vaccine, the most commonly reported side effects included pain, redness and swelling at the injection site, fatigue, headache, muscle pain, joint pain, chills, swelling of the lymph nodes in the same arm of the injection, nausea/vomiting and fever.

Data Supporting the Pfizer-BioNTech COVID-19 Vaccine, Bivalent Authorization

To evaluate the effectiveness of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine, Bivalent for individuals 12 years of age and older, the FDA analyzed immune response data among approximately 600 adults greater than 55 years of age who had previously received a 2-dose primary series and one booster dose with the monovalent Pfizer-BioNTech COVID-19 Vaccine. These participants received a second booster dose of either the monovalent Pfizer-BioNTech COVID-19 Vaccine or Pfizer-BioNTech’s investigational bivalent COVID-19 vaccine (original and omicron BA.1) 4.7 to 13.1 months after the first booster dose. After one month, the immune response against BA.1 of the participants who received the bivalent vaccine was better than the immune response of those who had received the monovalent Pfizer-BioNTech COVID-19 Vaccine.

The safety of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine, Bivalent for individuals 12 years of age and older is based on safety data from a clinical study which evaluated a booster dose of Pfizer-BioNTech’s investigational bivalent COVID-19 vaccine (original and omicron BA.1), safety data from clinical trials which evaluated primary and booster vaccination with the monovalent Pfizer-BioNTech COVID-19 Vaccine, and postmarketing safety data with the monovalent Pfizer-BioNTech COVID-19 Vaccine.

The safety data accrued with the bivalent vaccine (original and omicron BA.1) and with the monovalent Pfizer-BioNTech COVID-19 Vaccine are relevant to Pfizer-BioNTech COVID 19 Vaccine, Bivalent because these vaccines are manufactured using the same process.

The clinical study that evaluated the safety of a booster dose of the bivalent vaccine (original and omicron BA.1) included approximately 600 participants greater than 55 years of age who had previously received a 2-dose primary series, one booster dose of the monovalent Pfizer-BioNTech COVID-19 Vaccine, and then 4.7 to 13.1 months later, received a second booster dose of either the monovalent Pfizer-BioNTech COVID-19 Vaccine or Pfizer-BioNTech’s investigational bivalent COVID-19 vaccine (original and omicron BA.1). Among the study participants who received the bivalent vaccine, the most commonly reported side effects included pain, redness and swelling at the injection site, fatigue, headache, muscle pain, chills, joint pain, and fever.

The fact sheets for both bivalent COVID-19 vaccines for recipients and caregivers and for healthcare providers include information about the potential side effects, as well as the risks of myocarditis and pericarditis.

With today’s authorization, the FDA has also revised the EUA of the Moderna COVID-19 Vaccine and the Pfizer-BioNTech COVID-19 Vaccine to remove the use of the monovalent Moderna and Pfizer-BioNTech COVID-19 vaccines for booster administration for individuals 18 years of age and older and 12 years of age and older, respectively. These monovalent vaccines continue to be authorized for use for administration of a primary series for individuals 6 months of age and older as described in the letters of authorization. At this time, the Pfizer-BioNTech COVID-19 Vaccine remains authorized for administration of a single booster dose for individuals 5 through 11 years of age at least five months after completing a primary series of the Pfizer-BioNTech COVID-19 Vaccine.

The amendments to the EUAs were issued to Moderna TX Inc. and Pfizer Inc.

FDA Approval of Nonsteroidal Treatment for Duchenne Muscular Dystrophy

Breaking news! FDA approves Duvyzat for Duchenne Muscular Dystrophy, a nonsteroidal treatment providing hope for patients and families. #DMD #FDAApproval

Published

Breaking news in the medical world! The U.S. Food and Drug Administration has just approved Duvyzat (givinostat), an oral medication for the treatment of Duchenne Muscular Dystrophy (DMD) in patients six years of age and older. Duvyzat is making history as the first nonsteroidal drug approved to treat patients with all genetic variants of DMD. This is a significant milestone in the treatment of this devastating disease.

DMD, being the most common childhood form of muscular dystrophy, primarily affects males. It is a neurological disorder that leads to progressive muscle weakness due to a lack of dystrophin, a muscle protein. Over time, the muscles deteriorate, causing difficulties with walking, muscle strength, and eventually leading to breathing problems and early death. However, with advancements in treatment, the life expectancy for individuals with DMD has been steadily increasing, with some patients surviving beyond 30 years.

Duvyzat is a histone deacetylase (HDAC) inhibitor that targets pathogenic processes to reduce inflammation and loss of muscle in patients with DMD. Its efficacy for the treatment of DMD was evaluated in an 18-month phase 3 study involving a randomized, double-blind, placebo-controlled trial. The primary endpoint of the study was the change in muscle function, measured by the time it took patients to climb four stairs. Patients treated with Duvyzat showed a statistically significant reduction in the decline of muscle function compared to placebo.

Another measure of efficacy was the change in physical function assessed by the North Star Ambulatory Assessment (NSAA), a scale commonly used to rate motor function in boys with DMD who can still walk. Patients treated with Duvyzat experienced less worsening in their NSAA scores after 18 months, compared to those on placebo.

Like any medication, Duvyzat does come with some potential side effects. The most common ones reported were diarrhea, abdominal pain, a decrease in platelets, nausea/vomiting, an increase in triglycerides, and fever. It’s important for healthcare providers to evaluate a patient’s platelet counts and triglyceride levels before prescribing Duvyzat. Patients with low platelet counts should not take the drug. Monitoring of platelet counts and triglycerides throughout treatment will help determine if any dosage adjustments are needed.

Healthcare professionals should also be aware that Duvyzat may cause QTc prolongation, which can increase the risk of irregular heartbeats. It’s crucial for patients taking other medications known to cause QTc prolongation or with certain types of heart disease to avoid taking Duvyzat.

The recommended dosage of Duvyzat is determined by the patient’s body weight, and it should be taken orally twice daily with food.

The approval of Duvyzat was granted to Italfarmaco S.p.A., and it received priority review, fast-track designation, as well as orphan drug and rare pediatric disease designations from the FDA. This demonstrates the agency’s commitment to advancing the development of new therapies for DMD and its recognition of the urgent need for effective treatments.

This milestone approval represents hope and progress for individuals and families affected by DMD. It provides another treatment option to help reduce the burden of this progressive and debilitating disease, regardless of the specific genetic mutation. With continued advancements in medical research and the dedication of organizations like the FDA, we are moving closer to a future where individuals with DMD can lead healthier lives.

As always, it’s important to consult with healthcare professionals for more information and guidance regarding Duvyzat and its suitability for individual cases. Let’s celebrate this achievement in medical science and look forward to more groundbreaking developments in the treatment of Duchenne Muscular Dystrophy.

RSV, short for Respiratory Syncytial Virus, is a common viral infection that primarily affects the respiratory system, particularly young children. While RSV infections are usually mild, they can pose a greater risk to infants, older adults, and individuals with weakened immune systems. If you or a loved one are facing RSV, it can be overwhelming to know what to do next. That’s why it’s important to know the symptoms, treatment options, and preventative measures available to you. By being informed and taking action, you can give yourself and those around you hope and guidance during this difficult time. So let’s explore what you can do to fight RSV and emerge victorious.

Symptoms and Diagnosis:
RSV presents symptoms resembling a cold, including cough, runny nose, fever, and occasionally, difficulty breathing. Infants may exhibit irritability, decreased appetite, and lethargy. Diagnosing RSV usually involves a medical professional evaluating symptoms, conducting a physical examination, and, if necessary, performing laboratory tests to confirm the presence of the virus.

Treatment and Management:
In most cases, RSV infections can be managed at home with supportive care. This includes ensuring proper hydration, maintaining a comfortable environment, and using over-the-counter medications to alleviate symptoms under a doctor’s guidance. However, for high-risk individuals or severe cases, hospitalization may be required for closer monitoring and specialized treatment, such as oxygen therapy or intravenous fluids.

Prevention is Key:
Preventing the spread of RSV is crucial, especially for vulnerable populations. Practicing good hygiene, such as frequent handwashing, covering coughs and sneezes, and avoiding close contact with infected individuals, can significantly reduce the risk of transmission. Additionally, promoting a clean and sanitized environment, particularly in daycare centers and schools, can help curb the spread of the virus.

Hopeful Outlook:
While RSV can be concerning, it’s important to remember that most cases resolve on their own with time and supportive care. In fact, the majority of children infected with RSV recover fully without complications. By following preventive measures, seeking medical attention when needed, and staying informed about the latest developments in RSV research and treatment, we can approach this viral infection with hope and confidence.

Respiratory Syncytial Virus (RSV) is a common viral infection that primarily affects young children, causing cold-like symptoms and occasionally resulting in more severe respiratory distress. However, with proper care and attention, RSV can be managed effectively. By understanding the symptoms, seeking medical help when necessary, and adopting preventive measures, we can protect ourselves and our loved ones from the impact of RSV and look forward to brighter days ahead.

FDA Approves First Therapy for Rare Type of Non-Cancerous Tumors

Published

December 1, 2023

Daily News Staff

Today, the U.S. Food and Drug Administration approved Ogsiveo (nirogacestat) tablets for adult patients with progressing desmoid tumors who require systemic treatment. Ogsiveo is the first drug to be approved for the treatment of patients with desmoid tumors, a rare subtype of soft tissue sarcomas.

Desmoid tumors are non-cancerous but can be locally aggressive. The tumors may invade into surrounding structures and organs, resulting in pain, issues with being able to move, and decreased quality of life. Although surgical removal has historically been the treatment of choice, there is a high risk that the tumor will return or that other health challenges will occur after removal; therefore, systemic therapies (cancer treatment targeting the entire body) are being increasingly evaluated in clinical trials.

“The FDA continues to address unmet medical need and advance the development of safe and effective therapies for the millions of Americans whose lives are affected by rare tumors,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research. “Desmoid tumors are rare tumors that can lead to severe pain and disability. Today’s approval will offer the first approved treatment option for patients beyond surgery and radiation.”

The effectiveness of Ogsiveo was evaluated in an international, multicenter, randomized, double-blind, placebo-controlled trial in 142 adult patients with progressing desmoid tumors not amenable to surgery. Patients were randomized to receive 150 milligrams (mg) of Ogsiveo or placebo orally, twice daily, until disease progression or unacceptable toxicity. The main efficacy outcome measure was progression-free survival (the length of time after the start of treatment for which a person is alive and their cancer does not grow or spread). Objective response rate (a measure of tumor shrinkage) was an additional efficacy outcome measure.

The pivotal clinical trial demonstrated that Ogsiveo provided clinically meaningful and statistically significant improvement in progression-free survival compared to placebo. Additionally, the objective response rate was also statistically different between the two arms with a response rate of 41% in the Ogsiveo arm and 8% in the placebo arm. The progression-free survival results were also supported by an assessment of patient-reported pain favoring the Ogsiveo arm.

The most common side effects seen in at least 15% of the patients in the trial were diarrhea, ovarian toxicity, rash, nausea, fatigue, stomatitis, headache, abdominal pain, cough, alopecia, upper respiratory tract infection and dyspnea.

Ogsiveo was granted Priority Review under which the FDA’s goal is to take action on an application within six months where the agency determines that the drug, if approved, would significantly improve the safety or effectiveness of treating, diagnosing or preventing a serious condition compared to available therapies. Ogsiveo also received FDA Fast Track and Breakthrough Therapy designations for the indication noted above, as well as Orphan-Drug designation for treatment of desmoid tumor (aggressive fibromatosis). Orphan-drug designation provides incentives to assist and encourage drug development for rare diseases.

The FDA granted the approval of Ogsiveo to SpringWorks Therapeutics Inc.
