The U.S. Food and Drug Administration (FDA) has recently made a groundbreaking announcement by granting the first marketing authorization for a DNA test that assesses predisposition for dozens of cancer types. This significant development comes in the form of the Invitae Common Hereditary Cancers Panel, an in vitro diagnostic test capable of detecting genetic variants associated with an elevated risk of developing certain cancers. This test marks a major advancement in personalized medicine, as it can evaluate DNA samples to identify variants in 47 genes known to be linked with an increased likelihood of developing specific types of cancer.
By utilizing next-generation sequencing technology, the Invitae Common Hereditary Cancers Panel offers a comprehensive assessment of multiple genes in a single test. This enables healthcare professionals to gain valuable insights into an individual’s genetic predisposition for certain cancers. With this information, physicians can provide appropriate monitoring and potential therapies tailored to each patient’s specific needs.
Cancer remains one of the leading causes of death in the United States, and the availability of this test brings a vital public health tool into the hands of medical professionals. It equips them with additional information to guide patient care, potentially leading to earlier detection and intervention for those at higher risk. However, it is important to note that this test does not evaluate all known cancer-related genes, and patients should consult with a healthcare professional to interpret the results accurately.
The Invitae Common Hereditary Cancers Panel underwent rigorous evaluation by the FDA under the De Novo premarket review pathway. Extensive testing, involving over 9,000 clinical samples, demonstrated an accuracy rate of ≥99.0% for all tested variant types. While the test carries the possibility of false positive and false negative results, the risks are mitigated by the analytical and clinical performance validation, along with appropriate labeling.
In addition to granting marketing authorization, the FDA has established special controls that define requirements related to labeling and performance testing. These measures ensure the safety and effectiveness of similar devices in the future, potentially expediting the regulatory process for subsequent tests.
The FDA’s decision to grant marketing authorization for the Invitae Common Hereditary Cancers Panel is a significant milestone in the field of genetic testing and personalized medicine. It offers individuals valuable information about their health, empowering them to make informed decisions regarding monitoring and potential therapies. As technology continues to advance, such tests have the potential to revolutionize cancer care by enabling earlier detection and personalized treatment strategies.

Understanding RSV: Symptoms, Treatment, and Prevention
RSV: a viral respiratory infection affecting children and adults. Learn about symptoms, treatment, and prevention for a healthier future.
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.
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
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.
