A class I recall of certain Ellipse implantable cardioverter defibrillators by Abbott due to exposed aluminum wires that may prevent defibrillation therapy. The recall includes 108 devices distributed from May 6 to June 14, 2019.

A class I recall of the Volumat MC Agilia Infusion Pump and Vigilant Agilia Drug Library by Fresenius Kabi due to multiple software errors. The recall includes 9,461 infusion pumps and 83 copies of the optional Drug Library dose-error reduction software.

A class I recall of filter tips for use with QIAsymphony SP/AS instruments by QIAGEN due to a potential to leak, which may result in delayed or inaccurate results, including false-positive results, false-negative results, or incorrect quantification. The recall includes about 1.3 million tips in 1,240 kits distributed from Feb. 11 to March 9, 2019.

A recall of two lots of eletriptan hydrobromide (Relpax) 40-mg tablets by Pfizer Inc. due to potential microbiological contamination. Affected products were distributed from June to July 2019.

A warning not to purchase or drink Miracle Mineral Solution, a product sold online as a medical treatment, and other similar products due to a recent rise in reported health issues. The products are marketed as a liquid that is 28% sodium chlorite in distilled water. While not FDA approved for any use, these products are promoted on social media as a remedy for treating autism, cancer, HIV/AIDS, hepatitis, flu, and other conditions. When mixed with citric acid as directed, the solution develops into a dangerous bleach that has caused serious and potentially life-threatening side effects. The FDA has recently received reports of people experiencing severe vomiting, severe diarrhea, life-threatening low blood pressure caused by dehydration, and acute liver failure after drinking these products.

A class I recall of Alaris Infusion Sets for the Alaris Pump Model 8100 by Becton Dickinson due to the potential for over-infusion or an unintended delivery that occurs while the pump is not in a “running status.” The issue, which has been attributed to a device defect, has been associated with several reports of serious injuries. The recall includes more than 151 million devices distributed from July 1, 2016, to April 18, 2019.

A recall of certain models of the MiniMed insulin pump by Medtronic due to potential cybersecurity risks. About 4,000 U.S. patients may be affected. The risks are related to the pumps' wireless communication with other devices, such as blood glucose meters and continuous glucose monitoring systems. Due to the identified vulnerabilities, an unauthorized individual could potentially connect wirelessly to a nearby insulin pump and change its settings. Because the manufacturer cannot update the MiniMed 508 and MiniMed Paradigm series insulin pump models, patients using them should switch to a model with more cybersecurity protection. After the recall, the manufacturer provided patients with alternative insulin pumps that have enhanced cybersecurity capabilities. While waiting for a replacement pump, patients should try to keep their pump and connected devices within their control at all times. To date, the FDA is not aware of reports of patient harm related to these cybersecurity risks.

A recall of two lots of fluorouracil injection USP (5 g/100 mL [50 mg/mL]), 100-mL fill in 100-mL vials, by Fresenius Kabi USA, LLC, due to the potential for glass particulate. The affected lots were distributed between Dec. 6, 2018, and Feb. 20, 2019.

Miscellaneous

An updated letter to clinicians about the potential for increased long-term mortality after use of paclitaxel-coated balloons and paclitaxel-eluting stents to treat peripheral arterial disease (PAD) in the femoropopliteal artery. The agency has concluded that a late mortality signal was associated with the use of these devices to treat femoropopliteal PAD, although the magnitude of the signal should be interpreted with caution. Physicians should consider this risk when making treatment recommendations and continue diligent monitoring of patients who have been treated with paclitaxel-coated balloons and paclitaxel-eluting stents, the FDA recommended. The agency will continue to assess the long-term safety of these devices.

A safety announcement that an FDA review found no increased risk of prostate cancer with Parkinson's disease medicines containing entacapone (Comtan, Stalevo). The agency had alerted the public in March 2010 that a clinical trial had suggested a possible increased risk of prostate cancer with the entacapone component of Stalevo and asked the drug manufacturer to evaluate the potential risk in a study. The FDA also studied the issue independently using data from the Department of Veterans Affairs health care system. The additional studies concluded that entacapone use is not associated with an increased risk of prostate cancer.

A proposed rule to require new health warnings with color images on cigarette packages and in advertisements. The proposed warnings will feature photo-realistic color images depicting some of the lesser-known, but serious health risks of cigarette smoking. Examples of warnings include that smoking causes head and neck cancer, fatal lung disease in nonsmokers, and bladder cancer, which can lead to bloody urine. Health warnings on cigarette packages were last updated in 1984.

Approvals

The Barostim Neo System to improve symptoms in patients with advanced heart failure who cannot be treated with other heart failure devices, such as cardiac resynchronization therapy. The device is indicated for patients who have a left ventricular ejection fraction of less than or equal to 35%. It includes a pulse generator that is implanted below the collarbone and is connected to a lead that attaches to the carotid artery in the neck. A physician tests and programs the implanted device, which delivers electrical impulses to baroreceptors that sense how blood is flowing through the carotid arteries and relay information to the brain. The brain then sends signals that relax the blood vessels and inhibit the production of stress-related hormones to reduce heart failure symptoms. In a trial of 408 patients, all receiving guideline-directed medical therapy, 125 received the implant and showed improvements in six-minute walk distance and the impact of symptoms on quality of life. Potential complications include infection, need for reoperation, low blood pressure, nerve damage, surgical or anesthetic complications, allergic reaction, arterial damage, exacerbation of heart failure, stroke, and death. A postapproval study will assess the device's potential to prolong life and reduce hospitalizations.

Lefamulin (Xenleta) to treat adults with community-acquired bacterial pneumonia. The drug, which is taken either orally or intravenously, was compared to moxifloxacin, with or without linezolid, in two clinical trials of 1,289 patients. Patients in both groups had similar rates of clinical success. The most common reactions were diarrhea, nausea, reactions at the injection site, elevated liver enzymes, and vomiting. Because the drug may cause prolonged QT interval, it is contraindicated in patients with arrhythmias and those taking antiarrhythmic agents or drugs that may cause prolonged QT interval. In addition, it should not be used in patients with known hypersensitivity to lefamulin or any other members of the pleuromutilin antibiotic class.

Pretomanid tablets, in combination with bedaquiline and linezolid, to treat a specific type of highly treatment-resistant tuberculosis (TB) of the lungs. The drug is indicated to treat adult patients with extensively drug-resistant, treatment-intolerant, or nonresponsive multidrug-resistant pulmonary TB. A study of 109 patients found a success rate of 89% six months after the end of therapy, which exceeded historical success rates for treatment of extensively drug-resistant TB. The most common adverse reactions were peripheral neuropathy, acne, anemia, nausea, vomiting, headache, increased liver enzymes, dyspepsia, rash, hyperamylasemia, visual impairment, hypoglycemia, and diarrhea.

Expanded indication for several transcatheter heart valves to include patients with severe aortic valve stenosis who are at low risk for death or major complications associated with open-heart surgery to replace the damaged valves. The Sapien 3, Sapien 3 Ultra, CoreValve Evolut R, and CoreValve Evolut PRO were previously indicated only for patients at intermediate or higher risk for death or major complications during open-heart surgery. The transcatheter heart valves should not be used in patients who cannot tolerate blood-thinning medications or have an active infection in the heart or elsewhere. The FDA is requiring device manufacturers to follow patients enrolled in their randomized studies for 10 years to monitor safety and effectiveness, including long-term valve durability.

Entrectinib (Rozlytrek) to treat adults and adolescents whose cancer has a specific genetic defect, neurotrophic tyrosine receptor kinase (NTRK) gene fusion, and for whom there are no effective treatments. The orphan drug was also approved to treat adults with metastatic non-small-cell lung cancer whose tumors are ROS1-positive. This is the third cancer treatment approved by the FDA based on a common biomarker across different types of tumors, rather than the location of the tumor in the body. In four trials of 54 adults with NTRK fusion-positive tumors who received the drug, the proportion of patients with substantial tumor shrinkage was 57%, with 7.4% of patients having complete disappearance of the tumor. Among the 31 patients with tumor shrinkage, 61% had shrinkage persist for nine months or longer. In a study of 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 shrinkage persist for 12 months or longer. The most serious side effects include congestive heart failure, central nervous system effects, skeletal fractures, hepatotoxicity, hyperuricemia, QT prolongation, and vision disorders.

Pexidartinib (Turalio) capsules to treat adults with symptomatic tenosynovial giant cell tumor. The drug is indicated for patients with severe morbidity or functional limitations whose condition has not improved with surgery. Approval was based on a placebo-controlled trial of 120 patients. After 25 weeks of treatment, patients who received the drug had an overall response rate of 38%, compared to no response in patients who received placebo. The prescribing information contains a boxed warning about the risk of serious and potentially fatal liver injury. Common side effects include increases in lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, and cholesterol levels and loss of hair color. The drug is available only through a Risk Evaluation and Mitigation Strategy program.
