NEW DRUG APPROVALS
Kybella for Submental Fat
Deoxycholic acid (Kybella, Kythera Biopharmaceuticals Inc.) has received FDA approval to treat moderate-to-severe fat below the chin, called submental fat. The product is not approved or recommended to treat fat outside of the submental area.
Kybella is identical to the deoxycholic acid produced in the body, which helps the body absorb fats. A cytolytic drug, it destroys the cell membrane when injected into tissue. When properly injected into the fat tissue in the submental area, the drug destroys fat cells; however, it can also destroy other types of cells, such as skin cells, if it is inadvertently injected into the skin.
Adults may receive up to 50 injections in a single treatment, with up to six single treatments administered no less than one month apart. Only a licensed health care professional should provide the injections, and patients should understand the associated risks before considering treatment.
The safety and effectiveness of deoxycholic acid for treatment of submental fat were established in two clinical trials; 1,022 adults with moderate or severe submental fat were randomly assigned to receive deoxycholic acid or a placebo for up to six treatments. Reductions in submental fat were observed more frequently in participants who received deoxycholic acid versus placebo.
Deoxycholic acid can cause serious side effects, including nerve injury in the jaw that can cause an uneven smile or facial muscle weakness, and trouble swallowing. The most common side effects include swelling, bruising, pain, numbness, redness, and areas of hardness in the treatment area.
Deoxycholic acid is being provided in single-patient-use vials and should not be diluted or mixed with other compounds.

Tuzistra XR for Cough Relief
The FDA has approved codeine polistirex/chlorpheniramine polistirex extended-release oral suspension (Tuzistra XR, Vernalis LLC/Tris Pharma Inc.) to relieve coughs and symptoms associated with upper respiratory allergies or a common cold in patients 18 years of age and older.
Tuzistra XR, a Schedule III controlled substance, is meant to be dosed orally with or without food every 12 hours; it is not indicated for patients younger than 18 years of age. Codeine is an opiate agonist antitussive and chlorpheniramine is a histamine H1 receptor antagonist.
Tuzistra XR is contraindicated for postoperative pain management in children who have undergone tonsillectomy, adenoidectomy, or both. Respiratory depression and death have occurred in children who received codeine following those procedures and had evidence of being ultra-rapid metabolizers of codeine due to a cytochrome P450 CYP2D6 polymorphism. Tuzistra XR is also contraindicated in patients with known hypersensitivity to codeine, chlorpheniramine, or any of Tuzistra XR’s inactive ingredients. Persons known to be hypersensitive to certain other opioids may exhibit cross-sensitivity to codeine.

Aripiprazole From Four Companies
Four companies have received FDA approval to market aripiprazole, the first generic versions of the second-generation antipsychotic drug Abilify (Otsuka America Pharmaceutical, Inc.). Abilify has annual U.S. sales of approximately $7.8 billion, according to IMS data.
Alembic Pharmaceuticals, Hetero Labs Ltd., Teva Pharmaceuticals, and Torrent Pharmaceuticals can sell aripiprazole in multiple strengths and dosage forms. Otsuka is still seeking to protect some Abilify patents in court, but according to Teva (which has already launched its aripiprazole), a federal court has found that Otsuka’s likelihood of success is low.
Aripiprazole is approved to treat schizophrenia and bipolar disorder. Like all second-generation antipsychotics, it carries a boxed warning about an increased risk of death associated with off-label use to treat behavioral problems in older people with dementia-related psychosis. Its boxed warning also includes an increased risk of suicidal thinking and behavior in children, adolescents, and young adults taking antidepressants. Aripiprazole must be dispensed with a medication guide that describes important information about the drug’s uses and risks.

Cyramza for Colorectal Cancer
Ramucirumab injection 10 mg/mL solution (Cyramza, Eli Lilly) is now FDA-approved in combination with FOLFIRI chemotherapy (irinotecan, folinic acid, and 5-fluorouracil) to treat metastatic colorectal cancer that has progressed on or after therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine.
The approval—ramucirumab’s fourth—was based on results from the phase 3 RAISE trial, which compared ramucirumab plus FOLFIRI (n = 536) with placebo plus FOLFIRI (n = 536) every two weeks in this patient population. Patients treated with ramucirumab/FOLFIRI compared with placebo/FOLFIRI achieved a median overall survival of 13.3 months versus 11.7 months and a median progression-free survival of 5.7 months versus 4.5 months, respectively.
Ramucirumab is a vascular endothelial growth factor (VEGF) receptor-2 antagonist that specifically blocks the binding of VEGF receptor ligands VEGF-A, -C, and -D. In the U.S., it is approved for use as a single agent or in combination with paclitaxel to treat advanced or metastatic gastric or gastroesophageal junction adenocarcinoma that has progressed on or after prior fluoropyrimidine- or platinum-containing chemotherapy, and in combination with docetaxel for metastatic non–small-cell lung cancer that has progressed on or after platinum-based chemotherapy.
Ramucirumab’s labeling contains boxed warnings for hemorrhage, gastrointestinal perforation, and impaired wound healing as well as additional warnings and precautions for arterial thromboembolic events, hypertension, infusion-related reactions, clinical deterioration in patients with Child-Pugh B or C cirrhosis, reversible posterior leukoencephalopathy syndrome, proteinuria (including nephrotic syndrome), thyroid dysfunction, and embryofetal toxicity. The most common adverse events observed in ramucirumab/FOLFIRI patients included diarrhea, neutropenia, decreased appetite, epistaxis, and stomatitis.

Avelox for Plague
The FDA has approved moxifloxacin (Avelox, Bayer HealthCare Pharmaceuticals) to treat patients with pneumonic and septicemic plague. Avelox is also approved to prevent plague in adults.
Plague is extremely rare in most of the world, including the U.S., with 1,000 to 2,000 cases globally each year. The three most common forms are bubonic plague (infection of the lymph nodes), pneumonic plague (infection of the lungs), and septicemic plague (infection of the blood). Plague can be spread to humans through bites from infected fleas, contact with infected animals or humans, or laboratory exposure. The bacterium that causes plague, Yersinia pestis, is considered a potential bioterrorism agent.
Moxifloxacin’s approval was based on an efficacy study conducted in African green monkeys that were infected with Yersinia pestis in a laboratory setting. Animals were randomly selected to receive a 10-day regimen of moxifloxacin or placebo at least four hours after the onset of fever following exposure to Yersinia pestis. All 10 monkeys treated with moxifloxacin survived; none of the 10 monkeys treated with placebo survived.
Moxifloxacin’s common side effects are nausea, diarrhea, headache, and dizziness. It carries a boxed warning regarding an increased risk of tendinitis and tendon rupture and worsening of muscle weakness in people with myasthenia gravis. Other side effects include allergic reactions, liver damage, abnormalities of the blood, effects on the nervous system, and abnormal heart rhythm.

Breo Ellipta for Adult Asthma
The FDA has expanded the label for fluticasone furoate/vilanterol (Breo Ellipta, GlaxoSmithKline/Theravance, Inc.) to include once-daily treatment of asthma in patients 18 years of age and older.
Breo Ellipta was approved in May 2013 for long-term, once-daily maintenance treatment of airflow obstruction and for reducing exacerbations in patients with chronic obstructive pulmonary disease. It is not indicated for the relief of acute bronchospasm.
Breo Ellipta is a fixed-dose combination of the inhaled corticosteroid fluticasone furoate and the long-acting beta2 agonist (LABA) vilanterol. Two strengths, 100/25 mcg and 200/25 mcg, have been approved for use in asthma patients, administered once daily with the Ellipta dry-powder inhaler.
The FDA issued a complete response letter on the proposed use of the medication in patients ages 12 to 17 years stating that the data did not show an adequate risk–benefit ratio to support this approval. Additional data will be required to demonstrate the medication’s safety and efficacy in this population.
LABAs increase the risk of asthma-related death, and data from controlled clinical trials suggest that LABAs increase the risk of asthma-related hospitalization in pediatric and adolescent patients. When treating asthma patients, physicians should prescribe fluticasone furoate/vilanterol only for patients not adequately managed on a long-term asthma-control medication, such as an inhaled corticosteroid, or whose disease severity clearly warrants the initiation of treatment with both an inhaled corticosteroid and a LABA.
Once asthma control is achieved and maintained, the patient should be assessed at regular intervals; Breo Ellipta should be discontinued if possible without loss of asthma control and the patient should be kept on a long-term asthma control medication, such as an inhaled corticosteroid.

Venetoclax for CLL
Venetoclax (AbbVie/Roche) has received an FDA breakthrough therapy designation for the treatment of chronic lymphocytic leukemia (CLL) in relapsed/ refractory patients with the 17p deletion genetic mutation. Up to 10% of CLL patients have this mutation at diagnosis, and it occurs in up to 50% of patients with relapsed/refractory CLL.
Venetoclax is an investigational oral B-cell lymphoma-2 (BCL-2) inhibitor being evaluated for the treatment of several cancers. The BCL-2 protein prevents apoptosis of some cells, including lymphocytes, and can be expressed in some cancers. Venetoclax is being evaluated in phase 2 and 3 clinical trials for the treatment of CLL.

Xalkori for ROS1-Positive NSCLC
Crizotinib (Xalkori, Pfizer Inc.) has received an FDA breakthrough therapy designation for the treatment of ROS1-positive non–small-cell lung cancer (NSCLC), which accounts for approximately 1% of NSCLC.
The designation was based on data from an expansion cohort of the phase 1 Study 1001, which evaluated crizotinib in 50 patients with ROS1-positive advanced NSCLC. Crizotinib exhibited marked anti-tumor activity. Crizotinib, a kinase inhibitor, is FDA-approved to treat patients with metastatic NSCLC whose tumors are anaplastic lymphoma kinase–positive as detected by an FDA-approved test.

Idarucizumab to Reverse Dabigatran
The FDA has granted priority review to idarucizumab (Boehringer Ingelheim Pharmaceuticals, Inc.), a specific reversal agent for the anticoagulant effect of dabigatran, the active ingredient in the company’s Pradaxa. Idarucizumab would be used in patients needing emergency surgery or experiencing uncontrolled bleeding. The application for idarucizumab (which received breakthrough therapy status in June 2014) will be reviewed under the accelerated approval pathway. Currently, none of the novel oral anticoagulants has an approved reversal agent.
Phase 1 data showed the potential for idarucizumab, a humanized antibody fragment, to immediately reverse dabigatran’s anticoagulant effect with no clinically relevant adverse events. A phase 3 study, RE-VERSE AD, in ongoing.

AbbVie Genotype 4 HCV Drug
The FDA has awarded priority review to AbbVie’s all-oral, interferon-free treatment for adults chronically infected with hepatitis C virus genotype 4 (HCV GT4). The treatment combines ombitasvir/paritaprevir/ritonavir with ribavirin.
The FDA granted priority review based in part on results from HCV GT4 patients in the open-label, phase 2b PEARL-I study. After 12 weeks of treatment with the regimen, all of the 42 patients without cirrhosis who were new to therapy, and all of the 49 patients who had failed previous treatment with pegylated interferon and ribavirin, achieved a sustained virological response 12 weeks after the end of treatment (SVR12). Additionally, 40 of 44 patients (91%) who were new to therapy achieved SVR12 after taking the treatment without ribavirin.
HCV GT4 infection accounts for up to 6% of HCV infections. AbbVie’s regimen was granted a breakthrough therapy designation in June 2014.

Brilinta After Heart Attacks
Ticagrelor (Brilinta, AstraZeneca) will receive FDA priority review for a new indication: use in patients more than one year after a heart attack.
The new application is based on the PEGASUS-TIMI 54 study, in which 21,162 patients who had had a myocardial infarction (MI) one to three years earlier received ticagrelor 90 mg twice daily, ticagrelor 60 mg twice daily, or placebo, as well as low-dose aspirin. After a median 33 months of follow-up, the primary efficacy endpoint—a composite of cardiovascular death, MI, or stroke—was 7.85% for ticagrelor 90 mg, 7.77% for ticagrelor 60 mg, and 9.04% for placebo. Rates of Thrombolysis in Myocardial Infarction major bleeding were 2.60% with ticagrelor 90 mg, 2.30% with ticagrelor 60 mg, and 1.06% with placebo.
Brilinta, a direct-acting, selective, reversibly binding P2Y12 receptor antagonist, inhibits platelet activation. The 90-mg tablets are indicated to reduce the rate of thrombotic cardiovascular events in patients with acute coronary syndromes.

Pharmacists Help Lower BP
Patients referred to a pharmacist-run hypertension program had significantly improved blood pressure one year later, according to a study at Roudebush Veterans Affairs (VA) Medical Center in Indianapolis.
The study compared 465 patients with high blood pressure (BP) with 1,268 control participants. Six clinical pharmacists provided the hypertension care management program in four primary care clinics as part of the VA’s Patient-Aligned Care Team model. Patients were discharged from the program once they reached their BP goals, but could be sent back to the pharmacist for additional management.
At six and 12 months, systolic BP fell from baseline by −4.0 and −7.1 mm Hg, respectively, among program participants, compared with −1.6 and −2.6 mm Hg among controls. Diastolic BP dropped by −2.5 and −3.2 mm Hg at six and 12 months among the program’s patients, compared with −1.1 and −1.2 mm Hg in the control group. The researchers say their findings support pharmacists’ expanded role as part of the patient-centered model for improving hypertension and cardiovascular outcomes.
The pharmacists’ effect on BP was not necessarily due to improved adherence. Similar proportions of patients in both groups adhered to their antihypertensive medication regimen: 35% of the program’s patients and 32% of controls.
Instead, the improvements may have occurred because the pharmacists were tasked with changing the medication regimen to maximize effectiveness, “balancing the efficacy and safety of the medications with the preferences of the patient.” It’s possible, the researchers say, that the hypertension drug regimens the pharmacists initiated were more potent while avoiding or mitigating adverse effects.

Oncology Drug Spending Soars
Total global spending on oncology medications (including therapeutic treatments and supportive care) reached $100 billion in 2014, the IMS Institute for Healthcare Informatics reports. Spending on oncology drugs in the U.S. rose at a compounded annual growth rate of 5.3% in 2014 to reach $42.4 billion.
The report says the pace of change in cancer care is accelerating. Innovative treatments, often combined with other new or existing medicines and often associated with biomarkers, are emerging from the research-and-development pipeline. Many are for tumor types with low survival rates and limited treatment options.
The changing landscape is adding complexity for oncologists, payers, and governments seeking to provide appropriate patient care while ensuring the sustainability of health care systems. Earlier diagnosis, longer treatment duration, and increased effectiveness of drug therapies are contributing to rising spending. In most instances, five-year survival rates have risen through continuous small improvements in detection and treatment, including refinements with existing therapies.
Assessing oncology products’ value has become more complicated because most products have multiple indications. Of 88 cancer drugs marketed in 2014, 40 were for single indications and 48 were for multiple indications. By 2020, most cancer drugs will carry multiple indications, reflecting developers’ pursuit of genetic targets across multiple tumors and the rise of immuno-oncologic agents that may have more than six indications, the report predicts.

Home Health Care Infections
About 3.5% of patients being treated at home develop infections that lead to emergency care or hospitalization, Columbia University researchers say.
The researchers analyzed 2010 data from 199,462 patients and 8,255 home health care (HHC) agencies included in the national Outcome and Assessment Information Set. Of that sample, 11,476 patients (6%) received emergency care during HHC treatment, nearly always leading to hospital admission. About 5% of hospitalizations were planned, but 18% were not, and of those unplanned hospitalizations, 17% were caused by infections. In fact, three of the top six reasons for unplanned hospitalization were related to infections, most commonly respiratory, wound, urinary tract, and intravenous/catheter–related infections. The average time to developing an infection while receiving HHC was 24 days.
Agency-level infection rates varied from 0 to 100%, the researchers say, with an average of 3%. Because some agencies had very few patients, the researchers calculated the infection rate with agencies caring for 10 or more patients, yielding a rate of 3.5%. Approximately one-fourth of those agencies had no infections.
Infection rates may vary because the agencies follow different infection control practices. The researchers cite a 2002 article that estimated 1.2 million infections in HHC every year and called for national HHC infection surveillance—a system that has not been established. Moreover, the researchers say, evidence of infection control policy and practice in HHC is “sparse.” A study using a national representative sample, they suggest, could help HHC policy-makers understand practice adherence and make recommendations that improve HHC quality.

Aiding Constipation From Opioids
The combination of prolonged-release (PR) oxycodone and naloxone relieves pain and opioid-induced constipation (OIC) significantly better than PR oxycodone alone, Belgian researchers say.
In their study, 65 patients with laxative-refractory OIC received PR oxycodone alone or with naloxone at a median dose of 20 mg per day. Pain and constipation relief were assessed at three visits over 12 weeks.
The combination was superior to oxycodone alone in improving pain relief, OIC, and quality of life. The Bowel Function Index (BFI) showed a statistically significant improvement of 48.5 points from visit 1 to visit 3. A BFI change of 12 points or more has proven to be related to clinically meaningful changes in OIC patients’ bowel habits. The average BFI was less than 28.8 after patients took the combination for six weeks, indicating that most were no longer constipated.
The mean pain score was significantly lower with the combination. On a scale of 0 to 10, scores fell by an average of 2.1 during treatment to a mean score of 3.8 at 18 weeks.
The researchers say the median oxycodone/naloxone dose remained constant throughout the study and the number of patients who used analgesic rescue medication in the seven days before each visit fell from 44 (65%) to 26 (42%). That means increased doses or use of rescue medication can’t explain the improved pain relief, which is probably related to improved constipation relief.
Quality-of-life scores increased significantly and the number of patients using laxatives in the seven days before each visit dropped from 65 to 24 by visit 3. Only two patients reported adverse events, which were mild or unrelated to the study treatment.

A Targeted Approach to RA
Some patients with rheumatoid arthritis (RA) do well when their dose of tumor necrosis factor (TNF) inhibitor is reduced or stopped, but the results aren’t easy to predict. Findings from the Dose Reduction Strategy of Subcutaneous TNF Inhibitors (DRESS) study suggest that, in general, it may be alright to try a treat-to-target approach, in which the intervals between injections are lengthened until the patient has a flare or the drug can be stopped.
In this study of RA patients with low disease activity at two Dutch rheumatology outpatient clinics, 121 were assigned to dose-reduction treatment with adalimumab (Humira, AbbVie) or etanercept (Enbrel, Immunex) and 59 to usual care. The disease-activity strategy guided dose reduction stepwise, increasing the injection interval every three months.
At 18 months, the researchers found dose-reduction treatment was noninferior to usual care: 14 of 119 intervention patients (12%) had a major flare versus five of 50 usual-care patients (10%). In the dose-reduction group, TNF inhibitor use was successfully stopped in 24 patients (20%) and tapered in 52 (43%). At 18 months, 26% of patients on adalimumab had stopped and 36% had tapered its use. Of those on etanercept, 17% had stopped and 47% had tapered. Four patients in each group had switched to another drug.
Functional status, quality of life, radiographic progression, and adverse events did not differ between the two groups. However, the dose-reduction patients had more short-lived flares (73% versus 27%) and radiographic progression was twice as common (32% versus 15%). Roughly one-third of patients were not able to reduce doses.

Spirometry Underused in Asthma
Spirometry is recommended to help diagnose asthma, but its use—already low—has declined, University of Texas researchers report.
In 2007, the National Asthma Education and Prevention Program published comprehensive, evidence-based guidelines that included spirometry. Evaluating trends over the past 10 years, the Texas researchers analyzed data on 134,208 patients diagnosed with asthma and found that only 48% had spirometry within a year of diagnosis.
Spirometry plays a vital role in diagnosing and managing asthma by accurately measuring air volumes and flows. Guidelines recommend spirometry at the initial assessment; after treatment is initiated and symptoms and peak expiratory flow have stabilized; during periods of progressive or prolonged loss of asthma control; and at least every one to two years. But according to the American Academy of Allergy, Asthma, and Immunology, the researchers say, clinicians often rely on symptoms alone to diagnose and manage asthma, and symptoms may be misleading.
The decrease in spirometry use could be explained by a concurrent increase in asthma patients being treated solely by primary care practitioners, the researchers say. Patients who received care from a specialist, including allergists and pulmonary specialists, were more likely to receive spirometry. Of the 4,756 patients who were co-managed by primary care physicians, allergists, and pulmonary specialists, 92% had spirometry.
Use of short-acting bronchodilators and controller therapies was higher in asthma patients who had spirometry than those who did not. Among patients who did not have spirometry, 78% received at least one inhaler and more than 50% were on controller inhaler medications.
Although studies have found spirometry helps improve asthma care, surveys have revealed barriers to its use, such as lack of equipment and training. Still, the researchers cite some cost comparisons: spirometry, about $42; unnecessary use of an inhaled corticosteroid, $200 to $300 a month; and an emergency department visit for an asthma episode, about $3,500.

PTSD Increases Heart Failure
Veterans with post-traumatic stress disorder (PTSD) are nearly 50% more likely to develop heart failure than veterans without PTSD, according to an analysis of records from the Veterans Affairs Pacific Islands Health Care System.
Researchers reviewed medical records for 8,248 veterans treated as outpatients from 2005 to 2012. During the study, 1,712 veterans were diagnosed with PTSD. Over an average follow-up of seven years, 287 veterans without PTSD and 84 veterans with PTSD developed heart failure. The difference between the two groups’ rates held up even after researchers controlled for known clinical risk factors and military-specific factors, such as combat service.
The evidence linking PTSD to coronary heart disease is “substantial,” the researchers say. They note that veterans with PTSD are significantly more likely to have abnormal electrocardiograph results, myocardial infarctions, and atrioventricular conduction deficits than veterans without PTSD. They cite several hypotheses for the mechanisms by which PTSD contributes to heart disease. For instance, a hallmark symptom of PTSD—hyperarousal—and the subsequent sustained sympathetic nervous system activation affect the release of neurotransmitters and endocrine function, harming the cardiovascular system.

Ionsys Pain-Drug Device Approved for Hospital Use
The FDA has approved the fentanyl iontophoretic transdermal system (Ionsys, The Medicines Company), the first needle-free, patient-controlled, preprogrammed fentanyl delivery system, for the short-term management of acute postoperative pain in hospitalized adults who require opioid analgesia.
Patients recovering from surgery control their analgesic dosing by pushing a button to dispense fentanyl transdermally via an imperceptible electrical current as needed for pain. The device is to be used only for hospitalized patients enrolled in the Ionsys risk evaluation and mitigation strategy (REMS) program and is not meant for home use. The Ionsys REMS aims to mitigate the risk of respiratory depression resulting from accidental exposure to persons for whom it is not prescribed.
Ionsys, originally developed by Johnson & Johnson (J&J), won FDA approval in 2006. But after its launch in Europe in 2008, it was recalled because of device stability issues and never reached the U.S. market. The Medicines Company gained access to the treatment through its 2012 acquisition of Incline Therapeutics Inc., which had acquired the device from J&J in 2010.

Medtronic, FDA Agree on Synchromed II Restrictions
Medtronic, Inc., will stop making most Synchromed II Implantable Infusion Pump Systems—at least for now—after repeatedly failing to correct violations that FDA inspectors found at its production facilities, the agency said.
Medtronic and the FDA agreed to a consent decree, now awaiting federal court approval, against the company and two of its officers, S. Omar Ishrak and Thomas M. Tefft. The violations occurred at Medtronic’s Neuromodulation facilities in Columbia Heights, Minnesota, where the devices are made.
The Synchromed systems deliver medication to treat cancer, chronic pain, and severe spasticity. The consent decree requires Medtronic to stop manufacturing, designing, and distributing them except in very limited cases, such as when a physician determines that the system is medically necessary for a patient’s treatment.
Medtronic must also retain a third-party expert to help develop and submit plans to the FDA to correct violations. Until the FDA determines that the company has complied with all of the consent decree’s provisions, it will remain in effect. Once Medtronic receives FDA permission to resume the design, manufacture, and distribution of these products, the company must continue to submit audit reports to the FDA, which will also conduct its own inspections.
Medtronic said it expects to implement design changes to the SynchroMed pumps and enhance the Neuromodulation quality system.
The FDA approved the Synchromed II pumps in 2004, and first identified manufacturing problems in 2006 that can result in over- or under-infusion or a delay in therapy for patients. Between 2006 and 2013, the FDA conducted five inspections at Neuromodulation that resulted in three warning letters for major violations, including inadequate processes for identifying, investigating, and correcting quality problems; failure to document design changes; and failure to ensure that finished products meet design specifications.
Patients with an implanted Synchromed II pump should maintain regular follow-up appointments with their physicians. There is no need for patients to change their current course of therapy or have the pump removed.

Name: Myopore Sutureless Myocardial Pacing Lead
Manufacturer: Greatbatch Medical, Clarence, New York
Approval Date: April 30, 2015
Purpose: The Myopore Sutureless Myocardial Pacing Lead is indicated when ventricular epicardial attachment is required or when a transvenous lead cannot provide effective pacing.
Description: This device is a surgically implanted, insulated, and sutureless wire with a screw-in tip. It is part of a permanently implanted cardiac resynchronization therapy (CRT) device, pacemaker, or defibrillator.
Benefit: The Myopore pacing lead can be implanted using a small incision under the breastbone, allowing a less-invasive procedure for eligible patients; the lead is placed on the surface of the heart muscle and the screw-in tip can electrically stimulate the heart’s ventricles. This lead allows for use of a CRT device when other leads cannot be implanted, which gives various types of patients a viable option in controlling heart rhythm.
Manufacturer: The Medicines Company, Parsippany, New Jersey
Approval Date: April 30, 2015
Purpose: Raplixa helps control bleeding during surgery from small blood vessels when standard surgical techniques, such as suture, ligature, or cautery, are ineffective or impractical.
Description: Raplixa is a biological product containing fibrinogen and thrombin. It can be applied directly from the product vial or sprayed onto a bleeding site with the RaplixaSpray delivery device.
Benefit: This product provides surgeons with a convenient option to control bleeding during surgical procedures; the easy-to-use agent also works well across multiple bleeding settings. Approval was granted based on results from a phase 3, multicenter trial, which demonstrated that hemostasis was superior with Raplixa when compared to sponge alone.
Name: Senza System
Manufacturer: Nevro Corporation, Menlo Park, California
Approval Date: May 8, 2015
Purpose: This system aids in the management of chronic intractable pain of the trunk and/or limbs.
Description: A minimally invasive procedure is performed to implant the system into the patient’s body. It then delivers electrical stimulation to the lower-mid region of the back through implanted leads, which are connected to a rechargeable pulse generator that is implanted into the patient’s upper buttocks or abdomen. A remote control is used to operate the pulse generator within ranges programmed by the clinician.
Benefit: An increasing prevalence of chronic pain is seen in today’s society, with several options available to patients. Unfortunately, many of these systems are associated with paresthesia (a tingling sensation), which patients do not like. The Senza System can reduce pain without producing paresthesia by providing high-frequency stimulation (at 10 KHz) and low stimulation amplitudes, which may be preferred by patients suffering from chronic pain.
