Marketing of a new device to be used in the ED to treat patients with carbon monoxide poisoning. The ClearMate device delivers a mixture of oxygen and carbon dioxide in addition to 100% oxygen, which increases the patient's rate of breathing. In multiple studies that tested the device's effectiveness at eliminating carbon monoxide in 100 patients, the device led to faster elimination of carbon monoxide than treatment with 100% oxygen alone but was not faster than hyperbaric oxygen therapy. Patients did not experience any device-related complications.
A new generic of valsartan (Diovan), an angiotensin II receptor blocker (ARB). The approval is meant to help relieve the recent shortage of the medication as a result of multiple recalls of generic valsartan due to the detection of nitrosamine impurities. The FDA evaluated the company's manufacturing processes and also made sure it used appropriate testing methods to demonstrate that the product does not contain the impurities.
A new indication for the MitraClip Clip Delivery System to reduce moderate-to-severe or severe mitral regurgitation. The heart valve repair device, first approved in 2013, is now indicated for patients with normal mitral valves who develop heart failure symptoms and moderate-to-severe or severe mitral regurgitation because of diminished left-heart function despite optimal medical therapy. The device is contraindicated in patients who cannot tolerate blood thinners during or after the procedure and those who have active mitral valve endocarditis, rheumatic mitral valve disease, or evidence of blood clots in the heart or veins leading to the heart.
The Optimizer Smart System to restore a normal timing pattern of the heartbeat in patients with chronic, moderate-to-severe heart failure. The device is indicated for patients who have a marked limitation in physical activity, remain symptomatic despite optimal medical therapy, and are not suited for treatment with other heart failure devices (e.g., cardiac resynchronization therapy). The system includes an implantable pulse generator, battery charger, programmer, and software. After the device is implanted under the skin of the chest, a physician tests and programs the device, which delivers electrical impulses to the heart during regular heartbeats to help improve the heart's squeezing capability. In two randomized, multicenter trials of 389 patients with moderate-to-severe heart failure who all received medical therapy, patients who also received the implant showed improvements in six-minute walking distance, quality of life, and functional status compared to those who received medical therapy alone. Potential complications of the device include infection, bleeding, worsened heart failure, and problems with the device itself (e.g., dislodgement or fracture of the leads implanted in the heart).
Esketamine (Spravato) nasal spray, in conjunction with an oral antidepressant, to treat depression in adults with treatment-resistant depression. The drug, a chemical mirror image of ketamine, is only available through a restricted distribution system under a Risk Evaluation and Mitigation Strategy (REMS) because of the risk of serious adverse outcomes resulting from sedation and dissociation, as well as the potential for misuse. The drug must be self-administered in a certified medical office under the supervision of a clinician, who monitors the patient for at least two hours after administration. The spray may not be taken home, and patients should not drive or operate machinery until the next day. In one short-term study, the spray plus an oral antidepressant improved depressive symptoms significantly more than the oral antidepressant plus placebo, but two other short-term studies did not demonstrate effectiveness. In a longer-term trial, stable patients who continued treatment with the drug plus an oral antidepressant had a significantly longer time to relapse of depressive symptoms than those on a placebo plus an antidepressant. The most common side effects were dissociation, dizziness, nausea, sedation, vertigo, hypoesthesia, anxiety, lethargy, increased blood pressure, vomiting, and feeling drunk. The drug labeling contains a boxed warning about the serious risks of sedation, dissociation, misuse, and suicidal thoughts and behaviors.
Cladribine (Mavenclad) tablets to treat relapsing forms of multiple sclerosis (MS), including relapsing-remitting disease and active secondary progressive disease. The drug is generally indicated for patients who have had an inadequate response to, or are unable to tolerate, another MS drug. It is not recommended for patients who have clinically isolated syndrome. A trial of 1,326 patients found fewer relapses in those who received the drug compared to placebo. The drug also reduced the progression of disability compared to placebo. The most common adverse reactions include upper respiratory tract infections, headache, and decreased lymphocyte counts. The drug has a boxed warning for an increased risk of malignancy and fetal harm.
Siponimod (Mayzent) tablets to treat relapsing forms of MS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. A trial of 1,651 patients found a significantly lower proportion with confirmed progression of disability in three months in the treatment group versus a placebo group. The drug also decreased the number of relapses. The most common adverse reactions were headache, high blood pressure, and changes in liver function. Because the drug may increase the risk of infections, patients should have a complete blood count taken before initiating treatment.
Brexanolone (Zulresso) injection to treat women with postpartum depression. This is the first drug to be approved by the FDA specifically to treat postpartum depression. It will be available only through a REMS program that requires the drug to be administered by a clinician in a certified health care facility. The continuous IV infusion is administered over a total of 60 hours, and patients must have continuous pulse oximetry monitoring and must also be monitored for excessive sedation and sudden loss of consciousness. Patients must be accompanied during interactions with their child or children while receiving the infusion, and the need for these steps is addressed in a boxed warning. In two studies of patients with moderate or severe postpartum depression who received the treatment or placebo and were followed for four weeks, the drug was superior to placebo in improving depressive symptoms at the end of the first infusion, and this improvement was also found at the end of 30-day follow-up. The most common adverse reactions were sleepiness, dry mouth, loss of consciousness, and flushing.
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 in the femoropopliteal artery. A preliminary analysis of long-term follow-up data has identified about 50% increased long-term mortality in study participants treated with paclitaxel-coated products compared to patients treated with uncoated devices, the FDA said. The agency will hold an advisory committee meeting about the issue and provide updates as further information becomes available.
A letter to clinicians about an increasing number of adverse events associated with surgical staplers and staples for internal use. From Jan. 1, 2011, to March 31, 2018, the FDA received more than 41,000 related medical device reports, including 366 deaths, more than 9,000 serious injuries, and more than 32,000 malfunctions. The agency recommends following stapler manufacturers' instructions for use, having a range of staple sizes available, and selecting the appropriate size cartridge for the tissue type and thickness.
To ensure continued access to losartan, the FDA will not object to certain manufacturers temporarily distributing products containing NMBA above the interim acceptable intake limit of 0.96 parts per million (ppm) but below 9.82 ppm until the impurity is eliminated. The agency expects that many companies will be able to manufacture the drug without nitrosamine impurities and replenish the country's supply later this year.
