FDA approves first treatment Dupixent (Dupilumab) for chronic rhinosinusitis with nasal polyps


The U.S. Food and Drug Administration today approved Dupixent (dupilumab) to treat adults with nasal polyps (growths on the inner lining of the sinuses) accompanied by chronic rhinosinusitis (prolonged inflammation of the sinuses and nasal cavity). This is the first treatment approved for inadequately controlled chronic rhinosinusis with nasal polyps.

“Nasal polyps can lead to loss of smell and often patients require surgery to remove the polyps,” said Sally Seymour, M.D., Director of the Division of Pulmonary, Allergy and Rheumatology Products in the FDA’s Center for Drug Evaluation and Research. “Dupixent provides an important treatment option for patients whose nasal polyps are not …

The U.S. Food and Drug Administration today approved Dupixent (dupilumab) to treat adults with nasal polyps (growths on the inner lining of the sinuses) accompanied by chronic rhinosinusitis (prolonged inflammation of the sinuses and nasal cavity). This is the first treatment approved for inadequately controlled chronic rhinosinusis with nasal polyps.

“Nasal polyps can lead to loss of smell and often patients require surgery to remove the polyps,” said Sally Seymour, M.D., Director of the Division of Pulmonary, Allergy and Rheumatology Products in the FDA’s Center for Drug Evaluation and Research. “Dupixent provides an important treatment option for patients whose nasal polyps are not adequately controlled with intranasal steroids. It also reduces the need for nasal polyp surgery and oral steroids.”

Dupixent is given by injection. The efficacy and safety of Dupixent were established in two studies with 724 patients, 18 years and older with chronic rhinosinusitis with nasal polyps who were symptomatic despite taking intranasal corticosteroids. Patients who received Dupixent had statistically significant reductions in their nasal polyp size and nasal congestion compared to the placebo group. Patients taking Dupixent also reported an increased ability to smell and required less nasal polyp surgery and oral steroids.

Dupixent may cause serious allergic reactions and eye problems, such as inflammation of the eye (conjunctivitis) and inflammation of the cornea (keratitis). If patients experience new or worsening eye symptoms, such as redness, itching, pain or visual changes, they should consult their health care professional. The most common side effects reported include injection site reactions as well as eye and eyelid inflammation, which included redness, swelling and itching. Patients receiving Dupixent should avoid receiving live vaccines.

Dupixent was originally approved in 2017 for patients 12 and older with eczema that is not controlled adequately by topical therapies or when those therapies are not advisable. In 2018, Dupixent was approved as an add-on maintenance treatment for patients 12 years and older with moderate-to-severe eosinophilic asthma or with oral corticosteroid-dependent asthma.

The FDA granted this application Priority Review. The approval of Dupixent was granted to Regeneron Pharmaceuticals.

FDA approves treatment Inrebic (fedratinib) for patients with rare bone marrow disorder


FDA approves treatment Inrebic (fedratinib) for patients with rare bone marrow disorder

Today, the U.S. Food and Drug Administration approved Inrebic (fedratinib) capsules to treat adult patients with certain types of myelofibrosis.

“Prior to today, there was one FDA-approved drug to treat patients with myelofibrosis, a rare bone marrow disorder. Our approval today provides another option for patients,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “The FDA is committed to encouraging the development of treatments for patients with rare diseases and providing alternative options, as not all patients respond in the same way.”

Myelofibrosis is a chronic disorder where scar tissue forms in the bone marrow and the production of the blood cells moves from the bone marrow to the spleen and liver, causing organ enlargement. It can cause extreme fatigue, shortness of breath, pain below the ribs, fever, night sweats, itching and bone pain. When myelofibrosis occurs on its own, it is called primary myelofibrosis. Secondary myelofibrosis occurs when there is excessive red blood cell production (polycythemia vera) or excessive platelet production (essential thrombocythemia) that evolves into myelofibrosis.

Jakafi (ruxolitinib) was approved by the FDA in 2011. The approval of Inrebic for intermediate-2 or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis was based on the results of a clinical trial where 289 patients with myelofibrosis were randomized to receive two different doses (400 mg or 500 mg daily by mouth) of fedratinib or placebo. The clinical trial showed that 35 of 96 patients treated with the fedratinib 400 mg daily dose (the dose recommended in the approved label) experienced a significant therapeutic effect (measured by greater than or equal to a 35% reduction from baseline in spleen volume at the end of cycle 6 (week 24) as measured by an MRI or CT scan with a follow-up scan four weeks later). As a result of treatment with Inrebic, 36 patients experienced greater than or equal to a 50% reduction in myelofibrosis-related symptoms, such as night sweats, itching, abdominal discomfort, feeling full sooner than normal, pain under ribs on left side, and bone or muscle pain.

The prescribing information for Inrebic includes a Boxed Warning to advise health care professionals and patients about the risk of serious and fatal encephalopathy (brain damage or malfunction), including Wernicke’s, which is a neurologic emergency related to a deficiency in thiamine. Health care professionals are advised to assess thiamine levels in all patients prior to starting Inrebic, during treatment and as clinically indicated. If encephalopathy is suspected, Inrebic should be immediately discontinued.

Common side effects for patients taking Inrebic are diarrhea, nausea, vomiting, fatigue and muscle spasms. Health care professionals are cautioned that patients may experience severe anemia (low iron levels) and thrombocytopenia (low level of platelets in the blood). Patients should be monitored for gastrointestinal toxicity and for hepatic toxicity (liver damage). The dose should be reduced or stopped if a patient develops severe diarrhea, nausea or vomiting. Treatment with anti-diarrhea medications may be recommended. Patients may develop high levels of amylase and lipase in their blood and should be managed by dose reduction or stopping the mediation. Inrebic must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.

The FDA granted this application Priority Review designation. Inrebic also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases. The FDA granted the approval of Inrebic to Impact Biomedicines, Inc., a wholly-owned subsidiary of Celgene Corporation.

FDA approves third oncology drug Rozlytrek (entrectinib) that targets a key genetic driver of cancer, rather than a specific type of tumor


FDA approves third oncology drug Rozlytrek (entrectinib) that targets a key genetic driver of cancer, rather than a specific type of tumor 

FDA also approves drug for second indication in a type of lung cancer

The U.S. Food and Drug Administration today granted accelerated approval to Rozlytrek (entrectinib), a treatment for adult and adolescent patients whose cancers have the specific genetic defect, NTRK (neurotrophic tyrosine receptor kinase) gene fusion and for whom there are no effective treatments.

“We are in an exciting era of innovation in cancer treatment as we continue to see development in tissue agnostic therapies, which have the potential to transform cancer treatment. We’re seeing continued advances in the use of biomarkers to guide drug development and the more targeted delivery of medicine,” said FDA Acting Commissioner Ned Sharpless, M.D. “Using the FDA’s expedited review pathways, including breakthrough therapy designation and accelerated approval process, we’re supporting this innovation in precision oncology drug development and the evolution of more targeted and effective treatments for cancer patients. We remain committed to encouraging the advancement of more targeted innovations in oncology treatment and across disease types based on our growing understanding of the underlying biology of diseases.”

This is the third time the agency has approved a cancer treatment based on a common biomarker across different types of tumors rather than the location in the body where the tumor originated. The approval marks a new paradigm in the development of cancer drugs that are “tissue agnostic.” It follows the policies that the FDA developed in a guidance document released in 2018. The previous tissue agnostic indications approved by the FDA were pembrolizumab for tumors with microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) tumors in 2017 and larotrectinib for NTRK gene fusion tumors in 2018.

“Today’s approval includes an indication for pediatric patients, 12 years of age and older, who have NTRK-fusion-positive tumors by relying on efficacy information obtained primarily in adults. The FDA continues to encourage the inclusion of adolescents in clinical trials. Traditionally, clinical development of new cancer drugs in pediatric populations is not started until development is well underway in adults, and often not until after approval of an adult indication,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “Efficacy in adolescents was derived from adult data and safety was demonstrated in 30 pediatric patients.”

The ability of Rozlytrek to shrink tumors was evaluated in four clinical trials studying 54 adults with NTRK fusion-positive tumors. The proportion of patients with substantial tumor shrinkage (overall response rate) was 57%, with 7.4% of patients having complete disappearance of the tumor. Among the 31 patients with tumor shrinkage, 61% had tumor shrinkage persist for nine months or longer. The most common cancer locations were the lung, salivary gland, breast, thyroid and colon/rectum.

Rozlytrek was also approved today for the treatment of adults with non-small cell lung cancer whose tumors are ROS1-positive (mutation of the ROS1 gene) and has spread to other parts of the body (metastatic). Clinical studies evaluated 51 adults with ROS1-positive lung cancer. The overall response rate was 78%, with 5.9% of patients having complete disappearance of their cancer. Among the 40 patients with tumor shrinkage, 55% had tumor shrinkage persist for 12 months or longer.

Rozlytrek’s common side effects are fatigue, constipation, dysgeusia (distorted sense of taste), edema (swelling), dizziness, diarrhea, nausea, dysesthesia (distorted sense of touch), dyspnea (shortness of breath), myalgia (painful or aching muscles), cognitive impairment (confusion, problems with memory or attention, difficulty speaking, or hallucinations), weight gain, cough, vomiting, fever, arthralgia and vision disorders (blurred vision, sensitivity to light, double vision, worsening of vision, cataracts, or floaters). The most serious side effects of Rozlytrek are congestive heart failure (weakening or damage to the heart muscle), central nervous system effects (cognitive impairment, anxiety, depression including suicidal thinking, dizziness or loss of balance, and change in sleep pattern, including insomnia and excessive sleepiness), skeletal fractures, hepatotoxicity (damage to the liver), hyperuricemia (elevated uric acid), QT prolongation (abnormal heart rhythm) and vision disorders. Health care professionals should inform females of reproductive age and males with a female partner of reproductive potential to use effective contraception during treatment with Rozlytrek. Women who are pregnant or breastfeeding should not take Rozlytrek because it may cause harm to a developing fetus or newborn baby.

Rozlytrek was granted accelerated approval. This approval commits the sponsor to provide additional data to the FDA. Rozlytrek also received Priority ReviewBreakthrough Therapy and Orphan Drug designation. The approval of Rozlytrek was granted to Genentech, Inc.

FDA approves new antibiotic Xenleta (lefamulin) to treat community-acquired bacterial pneumonia


FDA approves new antibiotic  Xenleta (lefamulin) to treat community-acquired bacterial pneumonia

The U.S. Food and Drug Administration today approved Xenleta (lefamulin) to treat adults with community-acquired bacterial pneumonia.

“This new drug provides another option for the treatment of patients with community-acquired bacterial pneumonia, a serious disease,” said Ed Cox, M.D., M.P.H., director of FDA’s Office of Antimicrobial Products. “For managing this serious disease, it is important for physicians and patients to have treatment options. This approval reinforces our ongoing commitment to address treatment of infectious diseases by facilitating the development of new antibiotics.”

Community-acquired pneumonia occurs when someone develops pneumonia in the community (not in a hospital). Pneumonia is a type of lung infection that can range in severity from mild to severe illness and can affect people of all ages. According to data from the Centers from Disease Control and Prevention, each year in the United States, about one million people are hospitalized with community-acquired pneumonia and 50,000 people die from the disease.

The safety and efficacy of Xenleta, taken either orally or intravenously, was evaluated in two clinical trials with a total of 1,289 patients with CABP. In these trials, treatment with Xenleta was compared to another antibiotic, moxifloxacin with or without linezolid. The trials showed that patients treated with Xenleta had similar rates of clinical success as those treated with moxifloxacin with or without linezolid.

The most common adverse reactions reported in patients taking Xenleta included diarrhea, nausea, reactions at the injection site, elevated liver enzymes and vomiting. Xenleta has the potential to cause a change on an ECG reading (prolonged QT interval). Patients with prolonged QT interval, patients with certain irregular heart rhythms (arrhythmias), patients receiving treatment for certain irregular heart rhythms (antiarrhythmic agents), and patients receiving other drugs that prolong the QT interval should avoid Xenleta. In addition, Xenleta should not be used in patients with known hypersensitivity to lefamulin or any other members of the pleuromutilin antibiotic class, or any of the components of Xenleta. Based on findings of fetal harm in animal studies, pregnant women and women who could become pregnant should be advised of the potential risks of Xenleta to a fetus. Women who could become pregnant should be advised to use effective contraception during treatment with Xenleta and for two days after the final dose.

Xenleta received FDA’s Qualified Infectious Disease Product (QIDP) designation. The QIDP designation is given to antibacterial and antifungal drug products intended to treat serious or life-threatening infections under the Generating Antibiotic Incentives Now (GAIN) title of the FDA Safety and Innovation Act. As part of QIDP designation, Xenleta was granted Priority Review under which the FDA’s goal is to take action on an application within an expedited time frame.

The FDA granted the approval of Xenleta to Nabriva Therapeutics.

A key global challenge the FDA faces as a public health agency is addressing the threat of antimicrobial-resistant infections. Among the FDA’s other efforts to address antimicrobial resistance, is the focus on facilitating the development of safe and effective new treatments to give patients more options to fight serious infections.

FDA approves first treatment Soliris (eculizumab) for neuromyelitis optica spectrum disorder, a rare autoimmune disease of the central nervous system


The U.S. Food and Drug Administration today approved Soliris (eculizumab) injection for intravenous use for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive. NMOSD is an autoimmune disease of the central nervous system that mainly affects the optic nerves and spinal cord.

“Soliris provides the first FDA-approved treatment for neuromyelitis optica spectrum disorder, a debilitating disease that profoundly impacts patients’ lives,” said Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “This approval changes the landscape of therapy for patients with NMOSD.

The U.S. Food and Drug Administration today approved Soliris (eculizumab) injection for intravenous use for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive. NMOSD is an autoimmune disease of the central nervous system that mainly affects the optic nerves and spinal cord.

“Soliris provides the first FDA-approved treatment for neuromyelitis optica spectrum disorder, a debilitating disease that profoundly impacts patients’ lives,” said Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “This approval changes the landscape of therapy for patients with NMOSD. Having an approved therapy for this condition is the culmination of extensive work we have engaged in with drug companies to expedite the development and approval of safe and effective treatments for patients with NMOSD, and we remain committed to these efforts for other rare diseases.”

In patients with NMOSD, the body’s immune system mistakenly attacks healthy cells and proteins in the body, most often in the optic nerves and spinal cord. Individuals with NMOSD typically have attacks of optic neuritis, which causes eye pain and vision loss. Individuals also can have attacks resulting in transverse myelitis, which often causes numbness, weakness, or paralysis of the arms and legs, along with loss of bladder and bowel control. Most attacks occur in clusters, days to months to years apart, followed by partial recovery during periods of remission. Approximately 50% of patients with NMOSD have permanent visual impairment and paralysis caused by NMOSD attacks. According to the National Institutes of Health, women are more often affected by NMOSD than men and African Americans are at greater risk of the disease than Caucasians. Estimates vary, but NMOSD is thought to impact approximately 4,000 to 8,000 patients in the United States.

NMOSD can be associated with antibodies that bind to a protein called aquaporin-4 (AQP4). Binding of the anti-AQP4 antibody appears to activate other components of the immune system, causing inflammation and damage to the central nervous system.

The effectiveness of Soliris for the treatment of NMOSD was demonstrated in a clinical study of 143 patients with NMOSD who had antibodies against AQP4 (anti-AQP4 positive) who were randomized to receive either Soliris treatment or placebo. Compared to treatment with placebo, the study showed that treatment with Soliris reduced the number of NMOSD relapses by 94 percent over the 48-week course of the trial. Soliris also reduced the need for hospitalizations and the need for treatment of acute attacks with corticosteroids and plasma exchange.

Soliris has a boxed warning to alert health care professionals and patients that life-threatening and fatal meningococcal infections have occurred in patients treated with Soliris, and that such infections may become rapidly life-threatening or fatal if not recognized and treated early. Patients should be monitored for early signs of meningococcal infections and evaluated immediately if infection is suspected. Use should be discontinued in patients who are being treated for serious meningococcal infections. Health care professionals should use caution when administering Soliris to patients with any other infection. In the NMOSD clinical trial, no cases of meningococcal infection were observed.

Soliris is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Prescribers must enroll in the REMS program. Prescribers must counsel patients about the risk of meningococcal infection, provide the patients with the REMS educational materials and ensure patients are vaccinated with meningococcal vaccine(s). The drug must be dispensed with the FDA-approved patient Medication Guide that provides important information about the drug’s uses and risks.

The most frequently reported adverse reactions reported by patients in the NMOSD clinical trial were: upper respiratory infection, common cold (nasopharyngitis), diarrhea, back pain, dizziness, influenza, joint pain (arthralgia), sore throat (pharyngitis) and contusion.

The FDA granted the approval of Soliris to Alexion Pharmaceuticals.

Soliris was first approved by the FDA in 2007. The drug is approved to reduce destruction of red blood cells in adults with a rare blood disease called paroxysmal nocturnal hemoglobinuria, for the treatment of adults and children with a rare disease that causes abnormal blood clots to form in small blood vessels in the kidneys (atypical hemolytic uremic syndrome to inhibit complement-mediated thrombotic microangiopathy), and for the treatment of adults with Myasthenia Gravis who are anti-acetylcholine receptor antibody positive.

The FDA granted this application Priority Review. The use for NMOSD received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.

FDA approves new treatment Victoza (liraglutide) for pediatric patients with type 2 diabetes


The U.S. Food and Drug Administration today approved Victoza (liraglutide) injection for treatment of pediatric patients 10 years or older with type 2 diabetes. Victoza is the first non-insulin drug approved to treat type 2 diabetes in pediatric patients since metformin was approved for pediatric use in 2000. Victoza has been approved to treat adult patients with type 2 diabetes since 2010.

“The FDA encourages drugs to be made available to the widest number of patients possible when there is evidence of safety and efficacy,” said Lisa Yanoff, M.D, acting director of the Division of Metabolism and Endocrinology Products in the FDA’s Center for Drug Evaluation and Research. “Victoza has now been shown to improve blood sugar control in pediatric patients with type 2 diabetes.

The U.S. Food and Drug Administration today approved Victoza (liraglutide) injection for treatment of pediatric patients 10 years or older with type 2 diabetes. Victoza is the first non-insulin drug approved to treat type 2 diabetes in pediatric patients since metformin was approved for pediatric use in 2000. Victoza has been approved to treat adult patients with type 2 diabetes since 2010.

“The FDA encourages drugs to be made available to the widest number of patients possible when there is evidence of safety and efficacy,” said Lisa Yanoff, M.D, acting director of the Division of Metabolism and Endocrinology Products in the FDA’s Center for Drug Evaluation and Research. “Victoza has now been shown to improve blood sugar control in pediatric patients with type 2 diabetes. The expanded indication provides an additional treatment option at a time when an increasing number of children are being diagnosed with this disease.”

Type 2 diabetes is the most common form of diabetes, occurring when the pancreas cannot make enough insulin to keep blood sugar at normal levels. Although type 2 diabetes primarily occurs in patients over the age of 45, the prevalence rate among younger patients has been rising dramatically over the past couple of decades. The Diabetes Report Card published by the U.S. Centers for Disease Control and Prevention estimates that more than 5,000 new cases of type 2 diabetes are diagnosed each year among U.S. youth younger than age 20.

Victoza improves blood sugar levels by creating the same effects in the body as the glucagon-like peptide (GLP-1) receptor protein in the pancreas. GLP-1 is often found in insufficient levels in type 2 diabetes patients. Like GLP-1, Victoza slows digestion, prevents the liver from making too much glucose (a simple sugar), and helps the pancreas produce more insulin when needed. As noted on the label, Victoza is not a substitute for insulin and is not indicated for patients with type 1 diabetes or those with diabetic ketoacidosis, a condition associated with diabetes where the body breaks down fat too quickly because there is inadequate insulin or none at all. Victoza is also indicated to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes and established cardiovascular disease; however, its effect on major adverse cardiovascular events in pediatrics was not studied and it is not indicated for this use in children.

The efficacy and safety of Victoza for reducing blood sugar in patients with type 2 diabetes was studied in several placebo-controlled trials in adults and one placebo-controlled trial with 134 pediatric patients 10 years and older for more than 26 weeks. Approximately 64% of patients in the pediatric study had a reduction in their hemoglobin A1c (HbA1c) below 7% while on Victoza, compared to only 37% who achieved these results with the placebo. HbA1c is a blood test that is routinely performed to evaluate how well a patient’s diabetes is controlled, and a lower number indicates better control of the disease. These results occurred regardless of whether the patient also took insulin at the same time. Adult patients who took Victoza with insulin or other drugs that increase the amount of insulin the body makes (e.g., sulfonylurea) may have an increased risk of hypoglycemia (low blood sugar). Meanwhile, pediatric patients 10 years and older taking Victoza had a higher risk of hypoglycemia regardless of whether they took other therapies for diabetes.

The prescribing information for Victoza includes a Boxed Warning to advise health care professionals and patients about the increased risk of thyroid C-cell tumors. For this reason, patients who have had, or have family members who have ever had medullary thyroid carcinoma (MTC) should not use Victoza, nor should patients who have an endocrine system condition called multiple endocrine neoplasia syndrome type 2 (MEN 2). In addition, people who have a prior serious hypersensitivity reaction to Victoza or any of the product components should not use Victoza. Victoza also carries warnings about pancreatitis, Victoza pen sharing, hypoglycemia when used in conjunction with certain other drugs known to cause hypoglycemia including insulin and sulfonylurea, renal impairment or kidney failure, hypersensitivity and acute gallbladder disease. The most common side effects are nausea, diarrhea, vomiting, decreased appetite, indigestion and constipation.

The FDA granted this application Priority Review. The approval of Victoza was granted to Novo Nordisk.

FDA approves new treatment for hospital-acquired and ventilator-associated bacterial pneumonia


The U.S. Food and Drug Administration today approved a new indication for the previously FDA-approved drug, Zerbaxa (ceftolozane and tazobactam) for the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) in patients 18 years and older. The FDA initially approved Zerbaxa in 2014 to treat complicated intra-abdominal infections and for complicated urinary tract infections.

“A key global challenge we face as a public health agency is addressing the threat of antimicrobial-resistant infections,” said FDA Principal Deputy Commissioner Amy Abernethy, M.D., Ph.D. “Hospital-acquired and ventilator-associated bacterial pneumonia are serious infections that can result in death in some patients.

The U.S. Food and Drug Administration today approved a new indication for the previously FDA-approved drug, Zerbaxa (ceftolozane and tazobactam) for the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) in patients 18 years and older. The FDA initially approved Zerbaxa in 2014to treat complicated intra-abdominal infections and for complicated urinary tract infections.

“A key global challenge we face as a public health agency is addressing the threat of antimicrobial-resistant infections,” said FDA Principal Deputy Commissioner Amy Abernethy, M.D., Ph.D. “Hospital-acquired and ventilator-associated bacterial pneumonia are serious infections that can result in death in some patients. New therapies to treat these infections are important to meet patient needs because of increasing antimicrobial resistance. That’s why, among our other efforts to address antimicrobial resistance, we’re focused on facilitating the development of safe and effective new treatments to give patients more options to fight life-threatening infections.”

HABP/VABP occur in patients in hospitals or other health care facilities and can be caused by a variety of bacteria. According to data from the U.S. Centers for Disease Control and Prevention, HABP and VABP are currently the second most common type of hospital-acquired infection in the United States, and are a significant issue in patients in the intensive care unit (ICU).

The safety and efficacy of Zerbaxa for the treatment of HABP/VABP, administered via injection, was demonstrated in a multinational, double-blind study that compared Zerbaxa to another antibacterial drug in 726 adult patients hospitalized with HABP/VABP. The study showed that mortality and cure rates were similar between Zerbaxa and the comparator treatment.

The most common adverse reactions observed in the HABP/VABP trial among patients treated with Zerbaxa were elevated liver enzyme levels, renal impairment or failure, and diarrhea.
Zerbaxa should not be used in patients with known serious hypersensitivity to components of Zerbaxa, as well as hypersensitivity to piperacillin/tazobactam or other members of the beta lactam class of antibacterial drugs.

Zerbaxa received FDA’s Qualified Infectious Disease Product (QIDP) designation for the treatment of HABP/VABP. The QIDP designation is given to antibacterial and antifungal drug products intended to treat serious or life-threatening infections under the Generating Antibiotic Incentives Now (GAIN) title of the FDA Safety and Innovation Act. As part of QIDP designation, the Zerbaxa marketing application for the HABP/VABP indication was granted Priority Review under which the FDA’s goal is to take action on an application within an expedited time frame.

The FDA granted the approval of Zerbaxa for the treatment of HABP/VABP to Merck & Co., Inc.

Today, the U.S. Food and Drug Administration approved Piqray (alpelisib) tablets, to be used in combination with the FDA-approved endocrine therapy fulvestrant, to treat postmenopausal women, and men, with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA-mutated, advanced or metastatic breast cancer (as detected by an FDA-approved test) following progression on or after an endocrine-based regimen.

The FDA also approved the companion diagnostic test, therascreen PIK3CA RGQ PCR Kit, to detect the PIK3CA mutation in a tissue and/or a liquid biopsy. Patients who are negative by the therascreen test using the liquid biopsy should undergo tumor biopsy for PIK3CA mutation testing.

“Piqray is the first PI3K inhibitor to demonstrate a clinically meaningful benefit in treating patients with this type of breast cancer. The ability to target treatment to a patient’s specific genetic mutation or biomarker is becoming increasingly common in cancer treatment, and companion diagnostic tests assist oncologists in selecting patients who may benefit from these targeted treatments,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “For this approval, we employed some of our newer regulatory tools to streamline reviews without compromising the quality of our assessment. This drug is the first novel drug approved under the Real-Time Oncology Review pilot program. We also used the updated Assessment Aid, a multidisciplinary review template that helps focus our written review on critical thinking and consistency and reduces time spent on administrative tasks.”

Metastatic breast cancer is breast cancer that has spread beyond the breast to other organs in the body (most often the bones, lungs, liver or brain). When breast cancer is hormone-receptor positive, patients may be treated with anti-hormonal treatment (also called endocrine therapy), alone or in combination with other medicines, or chemotherapy.

The efficacy of Piqray was studied in the SOLAR-1 trial, a randomized trial of 572 postmenopausal women and men with HR-positive, HER2-negative, advanced or metastatic breast cancer whose cancer had progressed while on or after receiving an aromatase inhibitor. Results from the trial showed the addition of Piqray to fulvestrant significantly prolonged progression- free survival (median of 11 months vs. 5.7 months) in patients whose tumors had a PIK3CA mutation.

Common side effects of Piqray are high blood sugar levels, increase in creatinine, diarrhea, rash, decrease in lymphocyte count in the blood, elevated liver enzymes, nausea, fatigue, low red blood cell count, increase in lipase (enzymes released by the pancreas), decreased appetite, stomatitis, vomiting, weight loss, low calcium levels, aPTT prolonged (blood clotting taking longer to occur than it should), and hair loss.

Health care professionals are advised to monitor patients taking Piqray for severe hypersensitivity reactions (intolerance). Patients are warned of potentially severe skin reactions (rashes that may result in peeling and blistering of skin or mucous membranes like the lips and gums). Health care professionals are advised not to initiate treatment in patients with a history of severe skin reactions such as Stevens-Johnson Syndrome, erythema multiforme, or toxic epidermal necrolysis. Patients on Piqray have reported severe hyperglycemia (high blood sugar), and the safety of Piqray in patients with Type 1 or uncontrolled Type 2 diabetes has not been established. Before initiating treatment with Piqray, health care professionals are advised to check fasting glucose and HbA1c, and to optimize glycemic control. Patients should be monitored for pneumonitis/interstitial lung disease (inflammation of lung tissue) and diarrhea during treatment. Piqray must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.

Piqray is the first new drug application (NDA) for a new molecular entity approved under the Real-Time Oncology Review (RTOR) pilot program, which permits the FDA to begin analyzing key efficacy and safety datasets prior to the official submission of an application, allowing the review team to begin their review and communicate with the applicant earlier. Piqray also used the updated Assessment Aid (AAid), a multidisciplinary review template intended to focus the FDA’s written review on critical thinking and consistency and reduce time spent on administrative tasks. With these two pilot programs, today’s approval of Piqray comes approximately three months ahead of the Prescription Drug User Fee Act (PDUFA) VI deadline of August 18, 2019.

The FDA granted this application Priority Review designation. The FDA granted approval of Piqray to Novartis. The FDA granted approval of the therascreen PIK3CA RGQ PCR Kit to QIAGEN Manchester, Ltd.

FDA approves first treatment Ruzurgi (amifampridine)  for children with Lambert-Eaton myasthenic syndrome, a rare autoimmune disorder

The U.S. Food and Drug Administration today approved Ruzurgi (amifampridine) tablets for the treatment of Lambert-Eaton myasthenic syndrome (LEMS) in patients 6 to less than 17 years of age. This is the first FDA approval of a treatment specifically for pediatric patients with LEMS. The only other treatment approved for LEMS is only approved for use in adults.

“We continue to be committed to facilitating the development and approval of treatments for rare diseases, particularly those in children,” said Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “This approval will provide a much-needed treatment option for pediatric patients with LEMS who have significant weakness and fatigue that can often cause great difficulties with daily activities.”

LEMS is a rare autoimmune disorder that affects the connection between nerves and muscles and causes weakness and other symptoms in affected patients. In people with LEMS, the body’s own immune system attacks the neuromuscular junction (the connection between nerves and muscles) and disrupts the ability of nerve cells to send signals to muscle cells.

The U.S. Food and Drug Administration today approved Ruzurgi (amifampridine) tablets for the treatment of Lambert-Eaton myasthenic syndrome (LEMS) in patients 6 to less than 17 years of age. This is the first FDA approval of a treatment specifically for pediatric patients with LEMS. The only other treatment approved for LEMS is only approved for use in adults.

“We continue to be committed to facilitating the development and approval of treatments for rare diseases, particularly those in children,” said Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “This approval will provide a much-needed treatment option for pediatric patients with LEMS who have significant weakness and fatigue that can often cause great difficulties with daily activities.”

LEMS is a rare autoimmune disorder that affects the connection between nerves and muscles and causes weakness and other symptoms in affected patients. In people with LEMS, the body’s own immune system attacks the neuromuscular junction (the connection between nerves and muscles) and disrupts the ability of nerve cells to send signals to muscle cells. LEMS may be associated with other autoimmune diseases, but more commonly occurs in patients with cancer such as small cell lung cancer, where its onset precedes or coincides with the diagnosis of cancer. LEMS can occur at any age. The prevalence of LEMS specifically in pediatric patients is not known, but the overall prevalence of LEMS is estimated to be three per million individuals worldwide.

Use of Ruzurgi in patients 6 to less than 17 years of age is supported by evidence from adequate and well-controlled studies of the drug in adults with LEMS, pharmacokinetic data in adult patients, pharmacokinetic modeling and simulation to identify the dosing regimen in pediatric patients and safety data from pediatric patients 6 to less than 17 years of age.

The effectiveness of Ruzurgi for the treatment of LEMS was established by a randomized, double-blind, placebo-controlled withdrawal study of 32 adult patients in which patients were taking Ruzurgi for at least three months prior to entering the study. The study compared patients continuing on Ruzurgi to patients switched to placebo. Effectiveness was measured by the degree of change in a test that assessed the time it took the patient to rise from a chair, walk three meters, and return to the chair for three consecutive laps without pause. The patients that continued on Ruzurgi experienced less impairment than those on placebo. Effectiveness was also measured with a self-assessment scale for LEMS-related weakness that evaluated the feeling of weakening or strengthening. The scores indicated greater perceived weakening in the patients switched to placebo.

The most common side effects experienced by pediatric and adult patients taking Ruzurgi were burning or prickling sensation (paresthesia), abdominal pain, indigestion, dizziness and nausea. Side effects reported in pediatric patients were similar to those seen in adult patients. Seizures have been observed in patients without a history of seizures. Patients should inform their health care professional immediately if they have signs of hypersensitivity reactions such as rash, hives, itching, fever, swelling or trouble breathing.

The FDA granted this application Priority Review and Fast Track designations. Ruzurgi also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.

The FDA granted the approval of Ruzurgi to Jacobus Pharmaceutical Company, Inc.

First FDA-approved vaccine Dengvaxia for the prevention of dengue disease in endemic regions

First FDA-approved vaccine for the prevention of dengue disease in endemic regions

May 01, 2019

The U.S. Food and Drug Administration announced today the approval of Dengvaxia, the first vaccine approved for the prevention of dengue disease caused by all dengue virus serotypes (1, 2, 3 and 4) in people ages 9 through 16 who have laboratory-confirmed previous dengue infection and who live in endemic areas. Dengue is endemic in the U.S. territories of American Samoa, Guam, Puerto Rico and the U.S. Virgin Islands.

“Dengue disease is the most common mosquito-borne viral disease in the world and global incidence has increased in recent decades,” said Anna Abram, FDA deputy commissioner for policy, legislation, and international affairs. “The FDA is committed to working proactively with our partners at the U.S. Centers for Disease Control and Prevention, as well as international partners, including the World Health Organization, to combat public health threats, including through facilitating the development and availability of medical products to address emerging infectious diseases. While there is no cure for dengue disease, today’s approval is an important step toward helping to reduce the impact of this virus in endemic regions of the United States.”

The CDC estimates more than one-third of the world’s population is living in areas at risk for infection by dengue virus which causes dengue fever, a leading cause of illness among people living in the tropics and subtropics. The first infection with dengue virus typically results in either no symptoms or a mild illness that can be mistaken for the flu or another viral infection. A subsequent infection can lead to severe dengue, including dengue hemorrhagic fever (DHF), a more severe form of the disease that can be fatal. Symptoms may include stomach pain, persistent vomiting, bleeding, confusion and difficulty breathing. Approximately 95 percent of all severe/hospitalized cases of dengue are associated with second dengue virus infection. Because there are no specific drugs approved for the treatment of dengue disease, care is limited to the management of symptoms.

Each year, an estimated 400 million dengue virus infections occur globally according to the CDC. Of these, approximately 500,000 cases develop into DHF, which contributes to about 20,000 deaths, primarily among children. Although dengue cases are rare in the continental U.S., the disease is regularly found in American Samoa, Puerto Rico, Guam, the U.S. Virgin Islands, as well as Latin America, Southeast Asia and the Pacific islands.

“Infection by one type of dengue virus usually provides immunity against that specific serotype, but a subsequent infection by any of the other three serotypes of the virus increases the risk of developing severe dengue disease, which may lead to hospitalization or even death,” said Peter Marks, M.D., director of the FDA’s Center for Biologics Evaluation and Research. “As the second infection with dengue is often much more severe than the first, the FDA’s approval of this vaccine will help protect people previously infected with dengue virus from subsequent development of dengue disease.”

The safety and effectiveness of the vaccine was determined in three randomized, placebo-controlled studies involving approximately 35,000 individuals in dengue-endemic areas, including Puerto Rico, Latin America and the Asia Pacific region. The vaccine was determined to be approximately 76 percent effective in preventing symptomatic, laboratory-confirmed dengue disease in individuals 9 through 16 years of age who previously had laboratory-confirmed dengue disease. Dengvaxia has already been approved in 19 countries and the European Union.

The most commonly reported side effects by those who received Dengvaxia were headache, muscle pain, joint pain, fatigue, injection site pain and low-grade fever. The frequency of side effects was similar across Dengvaxia and placebo recipients and tended to decrease after each subsequent dose of the vaccine.

Dengvaxia is not approved for use in individuals not previously infected by any dengue virus serotype or for whom this information is unknown. This is because in people who have not been infected with dengue virus, Dengvaxia appears to act like a first dengue infection – without actually infecting the person with wild-type dengue virus – such that a subsequent infection can result in severe dengue disease.Therefore, health care professionals should evaluate individuals for prior dengue infection to avoid vaccinating individuals who have not been previously infected by dengue virus. This can be assessed through a medical record of a previous laboratory-confirmed dengue infection or through serological testing (tests using blood samples from the patient) prior to vaccination.

Dengvaxia is a live, attenuated vaccine that is administered as three separate injections, with the initial dose followed by two additional shots given six and twelve months later.

The FDA granted this application Priority Review and a Tropical Disease Priority Review Voucher under a program intended to encourage development of new drugs and biologics for the prevention and treatment of certain tropical diseases. The approval was granted to Sanofi Pasteur.
