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 a new antibacterial drug to treat a serious lung disease using a novel pathway to spur innovation


FDA approves a new antibacterial drug to treat a serious lung disease using a novel pathway to spur innovation

First drug granted approval under FDA’s Limited Population Pathway for Antibacterial and Antifungal Drugs, instituted to spur development of antibiotics for unmet medical needs

The U.S. Food and Drug Administration today approved a new drug, Arikayce (amikacin liposome inhalation suspension), for the treatment of lung disease caused by a group of bacteria, Mycobacterium avium complex (MAC) in a limited population of patients with the disease who do not respond to conventional treatment (refractory disease).

MAC is a type of nontuberculous mycobacteria (NTM) commonly found in water and soil. Symptoms of disease in patients with MAC include persistent cough, fatigue, weight loss, night sweats, and occasionally shortness of breath and coughing up of blood.

Release

The U.S. Food and Drug Administration today approved a new drug, Arikayce (amikacin liposome inhalation suspension), for the treatment of lung disease caused by a group of bacteria, Mycobacterium avium complex (MAC) in a limited population of patients with the disease who do not respond to conventional treatment (refractory disease).

MAC is a type of nontuberculous mycobacteria (NTM) commonly found in water and soil. Symptoms of disease in patients with MAC include persistent cough, fatigue, weight loss, night sweats, and occasionally shortness of breath and coughing up of blood.

“As bacteria continue to grow impervious to currently available antibiotics, we need to encourage the development of drugs that can treat resistant infections. That means utilizing novel tools intended to streamline development and encourage investment into these important endeavors,” said FDA Commissioner Scott Gottlieb, M.D. “This approval is the first time a drug is being approved under the Limited Population Pathway for Antibacterial and Antifungal Drugs, and it marks an important policy milestone. This pathway, advanced by Congress, aims to spur development of drugs targeting infections that lack effective therapies. We’re seeing a lot of early interest among sponsors in using this new pathway, and it’s our hope that it’ll spur more development and approval of antibacterial drugs for treating serious or life-threatening infections in limited populations of patients with unmet medical needs.”

Arikayce is the first drug to be approved under the Limited Population Pathway for Antibacterial and Antifungal Drugs, or LPAD pathway, established by Congress under the 21st Century Cures Act to advance development and approval of antibacterial and antifungal drugs to treat serious or life-threatening infections in a limited population of patients with unmet need. Approval under the LPAD pathway may be supported by a streamlined clinical development program. These programs may involve smaller, shorter or fewer clinical trials. As required for drugs approved under the LPAD pathway, labeling for Arikayce includes certain statements to convey that the drug has been shown to be safe and effective only for use in a limited population.

Arikayce also was approved under the Accelerated Approval pathway. Under this approach, the FDA may approve drugs for serious or life-threatening diseases or conditions where the drug is shown to have an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit to patients. The approval of Arikayce was based on achieving three consecutive negative monthly sputum cultures by month six of treatment. The sponsor of Arikayce will be required by the FDA to conduct an additional, post-market study to describe the clinical benefits of Arikayce.

The safety and efficacy of Arikayce, an inhaled treatment taken through a nebulizer, was demonstrated in a randomized, controlled clinical trial where patients were assigned to one of two treatment groups. One group of patients received Arikayce plus a background multi-drug antibacterial regimen, while the other treatment group received a background multi-drug antibacterial regimen alone. By the sixth month of treatment, 29 percent of patients treated with Arikayce had no growth of mycobacteria in their sputum cultures for three consecutive months compared to 9 percent of patients who were not treated with Arikayce.

The Arikayce prescribing information includes a Boxed Warning regarding the increased risk of respiratory conditions including hypersensitivity pneumonitis (inflamed lungs), bronchospasm (tightening of the airway), exacerbation of underlying lung disease and hemoptysis (spitting up blood) that have led to hospitalizations in some cases. Other common side effects in patients taking Arikayce were dysphonia (difficulty speaking), cough, ototoxicity (damaged hearing), upper airway irritation, musculoskeletal pain, fatigue, diarrhea and nausea.

The FDA granted this application Fast Track, Breakthrough Therapy, Priority Review, and Qualified Infectious Disease Product (QIDP) designations. QIDP designation is given to antibacterial products that treat serious or life-threatening infections under the Generating Antibiotic Incentives Now (GAIN) title of the FDA Safety and Innovation Act. Arikayce also received Orphan Drug designation, which provides additional incentives to assist and encourage the development of drugs for rare diseases.

The FDA granted approval of Arikayce to Insmed, Inc. of Bridgewater, NJ.

The U.S. Food and Drug Administration today approved Vabomere for adults with complicated urinary tract infections (cUTI), including a type of kidney infection, pyelonephritis, caused by specific bacteria. Vabomere is a drug containing meropenem, an antibacterial, and vaborbactam, which inhibits certain types of resistance mechanisms used by bacteria.

The U.S. Food and Drug Administration today approved Vabomere for adults with complicated urinary tract infections (cUTI), including a type of kidney infection, pyelonephritis, caused by specific bacteria. Vabomere is a drug containing meropenem, an antibacterial, and vaborbactam, which inhibits certain types of resistance mechanisms used by bacteria.

“The FDA is committed to making new safe and effective antibacterial drugs available,” said Edward Cox, M.D., director of the Office of Antimicrobial Products in the FDA’s Center for Drug Evaluation and Research. “This approval provides an additional treatment option for patients with cUTI, a type of serious bacterial infection.”

The safety and efficacy of Vabomere were evaluated in a clinical trial with 545 adults with cUTI, including those with pyelonephritis. At the end of intravenous treatment with Vabomere, approximately 98 percent of patients treated with Vabomere compared with approximately 94 percent of patients treated with piperacillin/tazobactam, another antibacterial drug, had cure/improvement in symptoms and a negative urine culture test. Approximately seven days after completing treatment, approximately 77 percent of patients treated with Vabomere compared with approximately 73 percent of patients treated with piperacillin/tazobactam had resolved symptoms and a negative urine culture.

The most common adverse reactions in patients taking Vabomere were headache, infusion site reactions and diarrhea. Vabomere is associated with serious risks including allergic reactions and seizures. Vabomere should not be used in patients with a history of anaphylaxis, a type of severe allergic reaction to products in the class of drugs called beta-lactams.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of antibacterial drugs, Vabomere should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

Vabomere was designated as a qualified infectious disease product (QIDP). This designation is given to antibacterial products that treat serious or life-threatening infections under the Generating Antibiotic Incentives Now (GAIN) title of the FDA Safety and Innovation Act. As part of its QIDP designation, Vabomere received a priority review.

The FDA granted approval of Vabomere to Rempex Pharmaceuticals.
