Immunization Update• At its October 2012 meeting, the ACIP voted to recommend

that healthcare personnel administer a dose of Tdap vaccine to pregnant women during each pregnancy—ideally at between 27 and 36 weeks’ gestation—regardless of the woman’s prior history of receiving Tdap.– Reported cases of pertussis have spiked– Youngest infants are the most vulnerable– Vaccinating the mother during pregnancy can protect the youngest

infants.– Tdap given at one pregnancy provides insufficient protection for

subsequent pregnancies– Data support the safety of Tdap for pregnant women and their infants

The CDC is expected to publish these recommendations in MMWR 2-22-2013

FDA Okays Pneumococcal Vaccine for Older Adults

• December 20, 2011 The FDA approved the pneumococcal 13-valent conjugate vaccine (manufactured by Wyeth Pharmaceuticals, marketed by Pfizer Inc) for adults aged 50 years and older for the prevention of pneumonia and invasive disease caused by the 13 Streptococcus pneumoniae serotypes contained in the vaccine.

• The move comes on the heels of the November 16, 2011, meeting of the FDA's Vaccines and Related Biologics Advisory Committee, in which the committee voted 14 to 1 in favor of expanding the indication for Prevnar 13 to adults.

CDC Recommends Immunocompromised Adults Get Prevnar 13 Vaccine

• June 21, 2012 the Centers for Disease Control and Prevention's Advisory Committee on Vaccine Practices voted 14 to 0 that adults "with AIDS, cancer, organ transplants, advanced kidney disease and other immune-weakening conditions" should be given pneumococcal vaccine Prevnar 13, including those "who've already had Pneumovax 23" The panel has not yet decided if "all adults 50 years old and older should get Prevnar 13."

ACIP Recommendations for PCV13 and PPSV23 Use

• Adults with specified immunocompromising conditions who are eligible for pneumococcal vaccine should be vaccinated with PCV13 during their next pneumococcal vaccination opportunity.

• Pneumococcal vaccine-naïve persons. ACIP recommends that adults aged ≥19 years with immunocompromising conditions, functional or anatomic asplenia, CSF leaks, or cochlear implants, and who have not previously received PCV13 or PPSV23, should receive a dose of PCV13 first, followed by a dose of PPSV23 at least 8 weeks later. Subsequent doses of PPSV23 should follow current PPSV23 recommendations for adults at high risk. Specifically, a second PPSV23 dose is recommended 5 years after the first PPSV23 dose for persons aged 19–64 years with functional or anatomic asplenia and for persons with immunocompromising conditions. Additionally, those who received PPSV23 before age 65 years for any indication should receive another dose of the vaccine at age 65 years, or later if at least 5 years have elapsed since their previous PPSV23 dose.

– MMWR October 12, 2012 / 61(40);816-819

ACIP Recommendations for PCV13 and PPSV23 Use

• Previous vaccination with PPSV23. Adults aged ≥19 years with immunocompromising conditions, functional or anatomic asplenia, CSF leaks, or cochlear implants, who previously have received ≥1 doses of PPSV23 should be given a PCV13 dose ≥1 year after the last PPSV23 dose was received. For those who require additional doses of PPSV23, the first such dose should be given no sooner than 8 weeks after PCV13 and at least 5 years after the most recent dose of PPSV23. – MMWR October 12, 2012 / 61(40);816-819

CAPiTA Trial Preliminary Results• The 85,000-patient study in the Netherlands, called

CAPiTA, showed that Prevnar 13 prevented invasive pneumococcal disease, meaning infections of Streptococcus pneumoniae bacteria in patients age 65 and older.– 45.56% fewer first episodes of vaccine-type CAP among

Prevenar 13-vaccinated subjects than in subjects who received placebo (P=0.0006).

– Secondary objectives, the Prevenar 13 group experienced 45.00 % fewer first episodes of non-bacteremic/non-invasive vaccine-type CAP (P=0.0067) and 75.00 % fewer first episodes of vaccine-type IPD (P=0.0005) compared with the placebo group

– To be reviewed by ACIP and FDA

Influenza Vaccine in Patients with Egg Allergy?

• The American College of Allergy, Asthma and Immunology "The very low risk of reacting to the injection is greatly outweighed by the risks associated with the flu."

• ACAAI recommends that those with a previous history of egg allergy get the injectable vaccine in a medical facility where any allergic emergencies can be recognized and treated if they occur. For those who have had serious reactions after eating eggs, the vaccine should be administered in an allergist's office.

• In the past, there was concern that because the flu vaccine is grown in eggs, residual protein could trigger a reaction in those with allergies.

Page 10: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Influenza Vaccine in Patients with Egg Allergy?

• June 21, 2012 The ACIP meeting marked the 1-year anniversary of a change in recommendations that removed egg allergy as a contraindication to influenza vaccination, and it does not appear that the modification affected the rate of allergic reactions, according to data from the Vaccine Adverse Event Reporting System (VAERS).

Page 11: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Influenza Vaccine in Patients with Egg Allergy?

• June 20, 2013 the ACIP recommended Protein Science's FluBlok for the 2013-14 season in a 13 to 0 vote for patients with a history of egg allergy.– A recently approved cell-based flu vaccine

Flucelvax, made by Novartis, uses flu viruses grown in mammalian cells rather than chicken eggs and is thought to contain hardly any traces of egg. However, the vaccine seed strain used to make the vaccine is passaged in eggs, meaning it could contain a minuscule amount of albumin.

Page 12: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Influenza Vaccines for 2013-14• Influenza formulation changes for the 2013-

2014 vaccine have been announced. Trivalent vaccine (IIV3) will cover: – A/California/7/2009 (H1N1)-like virus; (H3N2)

virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011; and B/Massachusetts/2/2012-like virus.

• Quadrivalent vaccine (IIV4) will also include additional B virus coverage: – B/Brisbane/60/2008-like virus– Note that the FDA must first approve any changes before they can be made

Page 13: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Recently-FDA approved Influenza Vaccines for 2013-14 Season

• Quadrivalent Live-attenuated Influenza Vaccine (LAIV4)—Flumist Quadrivalent (MedImmune) age 2-49 (2 influenza A and 2 influenza B strains)

• Quadrivalent Inactivated Influenza Vaccine (IIV4)—Fluarix Quadrivalent (GSK) age 3 and older and Fluzone Quadrivalent (Sanofi) age 6 mo and older both have (2 influenza A and 2 influenza B strains)

• Cell-culture based inactivated influenza vaccine (ccIIV3)—Flucelvax (Novartis) age 18 and older

• Recombinant hemagglutinin vaccine (RIV3)—FluBlok (Protein Sciences) age 18-49

Influenza Vaccine Efficacy• Interim results for the 2013–14 season indicate that

vaccination has reduced the risk for influenza-associated medical visits by approximately 60%. (MMWR 2-21-2014)

• Last year the vaccine was less effective and we now may know why?– A British Columbia research team found that mutations in the

H3N2 virus occurred when a common strain of the virus chosen for the manufacture of a vaccine was modified. Although this so-called reference strain was initially well-matched to the virus it was intended to protect against, it had to be altered to grow better in chicken eggs to produce the vaccine. It was at this stage in the vaccine-making process that the misstep occurred.

Page 16: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Chemotherapy for Influenza?• When used as a treatment, both neuraminidase inhibitors cut the time

to the relief of symptoms -- by about 17 hours for oseltamivir and 14 hours for zanamivir.

• When used as prophylaxis in people exposed to the flu, both reduced the risk of symptomatic disease but not asymptomatic infection and therefore would have little effect on the risk of transmission during a pandemic.

• Oseltamivir caused nausea and vomiting and increased the risk of headaches, renal events (decreased creatinine clearance) and psychiatric syndromes (such as confusion and depression).

• Zanamivir, an inhaled drug, was linked to cases of bronchospasm, but was mostly well tolerated, possibly because it has a low bioavailability.

• Neither drug was shown to reduce the risk of hospital admission for flu, although there was a slight reduction in self-reported but unverified pneumonia among adults for both drugs.– BMJ 2014;348:g2371; g2524; g2545; g2548 from the Cochrane Reviews

Page 17: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

FDA approves Flucelvax by Novartis• November 20, 2012 The U.S. Food and Drug Administration

announced today the approval of Flucelvax, the first seasonal influenza vaccine licensed in the United States produced using cultured animal cells, instead of fertilized chicken eggs. Flucelvax is approved to prevent seasonal influenza in people ages 18 years and older.

• The manufacturing process for Flucelvax is similar to the egg-based production method, the virus strains included in the vaccine are grown in animal cells of mammalian origin instead of in eggs. Cell culture technology has already been in use for several decades to produce other U.S. licensed vaccines (polio, rubella and hepatitis A).

• A “subunit” influenza virus vaccine prepared from virus propagated in Madin Darby Canine Kidney (MDCK) cells.

Flublok by Protein Sciences Corporation

• Flublok (Influenza Vaccine) Sterile Solution for Intramuscular Injection contains purified HA proteins produced in a continuous insect cell line (expresSF+®) that is derived from Sf9 cells of the fall armyworm, Spodoptera frugiperda, and grown in serum-free medium composed of chemically-defined lipids, vitamins, amino acids, and mineral salts.

• Flublok is approved for use in persons 18 through 49 years• Flublok has a shorter shelf life, with an expiration period of

16 weeks from the production date, as compared to currently available inactivated influenza vaccines which carry an expiration date of June 30– For the 2012 - 2013 influenza season it is formulated to contain 135

mcg HA per 0.5 mL dose, with 45 mcg HA of each of the following 3 influenza virus strains: A/California/7/2009 (H1N1), A/Victoria/361/2011 (H3N2), and B/Wisconsin/1/2010. FDA approval 12-21-2012

Page 19: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

ACIP Meeting 10-25-2013• Fluzone High-Dose was 24.2% more effective in preventing

influenza in 32,000 adults aged 65 years or older than regular Fluzone in a large-scale 2 year clinical trial conducted in the US and Canada, vaccine maker Sanofi Pasteur told the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention today.

• The rate of laboratory-confirmed influenza among participants receiving Fluzone High-Dose was 1.43% compared with 1.89% among patients immunized with Fluzone. For the FDA to deem Fluzone High-Dose as superior, the vaccine needed to demonstrate a relative efficacy rate of at least 9.1%. It achieved a rate more than twice that — RRR=24.2%, ARR = 0.46%, NNT 218

H5N1 Avian Influenza Vaccine• Nov 22, 2013 Vaccine to supplement National

Stockpile, not intended for commercial availability but it is intended to be made available to the public in a pandemic outbreak.

• The vaccine, Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted, is for use in people 18 years of age and older who are at increased risk of exposure to the H5N1 avian influenza virus.

Page 21: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

H5N1 Avian Influenza Vaccine

• Most avian influenza A viruses do not infect people. However some viruses, such as H5N1, have caused serious illness and death in people outside of the U.S., mostly among people who have been in close contact with infected and ill poultry. When people do become infected with H5N1, about 60 percent die, according to the World Health Organization.

Page 22: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

H5N1 Avian Influenza Vaccine• The H5N1 component and the AS03 adjuvant

component are supplied in two separate vials, which must be combined prior to use. The vaccine is administered via intramuscular injection in two doses, 21 days apart.

• Safety data comes from approximately 3,400 adults 18 years of age and older – Muscle aches, headache, fatigue and injection site

pain, redness and swelling were common.

Page 23: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Meningitis type B• Meningitis type B is responsible for about a third of U.S.

meningitis cases, but is the only strain not currently preventable by an FDA-approved vaccine.

• In the last year MenB has infected more than a dozen students at Princeton, UC-Santa Barbara, and Drexel.

• MenB is a potentially deadly disease which is easily misdiagnosed and can kill within 24 hours of onset. About one in 10 of those who contract the disease will die despite appropriate treatment. Up to one in five survivors may suffer from devastating, life-long disabilities such as brain damage, hearing impairment or limb loss.

Acetaminophen UpdateJanuary 13, 2011 FDA Drug Safety Communication: Prescription Acetaminophen Products to be Limited to 325 mg Per Dosage Unit - The FDA is asking drug manufacturers to limit the strength of acetaminophen in prescription drug products, which are predominantly combinations of acetaminophen and opioids. This action will limit the amount of acetaminophen in these products to 325 mg per tablet, capsule, or other dosage unit, making these products safer for patients. • Drug companies will have three years from the date of publication of the

Federal Register Notice (January 14, 2011) to limit the amount of acetaminophen in their oral prescription drug products to 325 mg per dosage unit (see the Federal Register Notice2 Docket number FDA-2011-N-0021-0001).

• In addition, a Boxed Warning highlighting the potential for severe liver injury and a Warning highlighting the potential for allergic reactions (e.g., swelling of the face, mouth, and throat, difficulty breathing, itching, or rash) are being added to the label of all prescription drug products that contain acetaminophen.

Page 26: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

FDA recommends against prescribing and dispensing prescription combination drug products with more

than 325 mg of acetaminophen

• More than half of manufacturers have voluntarily complied with our request. However, some prescription combination drug products containing more than 325 mg of acetaminophen per dosage unit remain available.

• In the near future we intend to institute proceedings to withdraw approval of prescription combination drug products containing more than 325 mg of acetaminophen per dosage unit that remain on the market.– FDA Jan 14, 2014

DEA Notice of Proposed Rule Making Feb 27, 2014

• The Drug Enforcement Administration (DEA) proposes to reschedule hydrocodone combination products from schedule III to schedule II of the Controlled Substances Act. This proposed action is based on a rescheduling recommendation from the Assistant Secretary for Health of the Department of Health and Human Services and an evaluation of all other relevant data by the DEA. If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule II controlled substances.

• The DEA will receive comments until April 28, 2014

FDA Approves Zohydro ER C-II• 10/26/2013 The U.S. Food and Drug Administration

today approved Zohydro ER (hydrocodone bitartrate extended-release capsules) by Zogenix for the management of pain severe enough to require daily, around-the-clock, long-term treatment and for which alternative treatment options are inadequate. – The first FDA-approved single-entity (not

combined with an analgesic such as acetaminophen) and extended-release hydrocodone product.

Page 30: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Hydrocodone bitartrate extended-release capsules – Zohydro ER

• ER/LA opioid formulations like Zohydro ER should be reserved for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. Zohydro ER is not approved for as-needed pain relief.– The approved labeling for Zohydro ER conforms

to updated labeling requirements for all ER/LA opioid analgesics announced by the FDA on Sept. 10, 2013.

Page 31: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Hydrocodone bitartrate extended-release capsules – Zohydro ER

• Extended-release capsules: 10 mg, 15 mg, 20 mg, 30 mg, 40 mg and 50 mg– Capsules must be swallowed whole and are not to be

chewed, crushed or dissolved.

• For opioid-naïve and opioid non-tolerant patients, initiate with 10 mg capsules orally every 12 h. To convert to Zohydro ER from another opioid, use available conversion factors to obtain estimated dose.

• Increase the dose of Zohydro ER in increments of 10 mg every 12 hours every 3 to 7 days as needed to achieve adequate analgesia.

EVZIO (Naloxone) Auto-Injector

Dosage and Administration:• EVZIO is for intramuscular or subcutaneous use only. • Administer EVZIO to adult or pediatric patients into the

anterolateral aspect of the thigh, through clothing if necessary. – Additional doses may be administered every 2 to 3 minutes

until emergency medical assistance arrives. • In pediatric patients under the age of one, the caregiver

should pinch the thigh muscle while administering the dose

• Seek emergency medical care immediately after use.

Page 35: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

EVZIO (Naloxone) Auto-Injector• Naloxone is fast onset with peak levels in about

15 min and a half-life of ~1.5 hours (~3.0 hours in neonates)

• Naloxone will produce rapid reversal of the respiratory and CNS effects of opioids but may only last for 2-3 hours– Reversal of partial agonist/antagonists like

buprenorphone and pentazocine maybe slow and incomplete especially with buprenorphone and may require larger repeat doses

Page 36: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

EVZIO (Naloxone) Auto-Injector

• Patients on long-term opioids will experience opioid withdrawal with nausea, vomiting, sweating, increased heart rate, increased blood pressure, tremors, weakness, body aches and potential seizures as well as increased risk of cardiac events.

• In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated

FDA Drug Safety Communication - Olmesartan

• 7-3-2013 FDA approves label changes to include intestinal problems (sprue-like enteropathy) linked to blood pressure medicine olmesartan medoxomil (Benicar, Azor, Tribenzor)– Symptoms of sprue-like enteropathy include severe,

chronic diarrhea with substantial weight loss. The enteropathy may develop months to years after starting olmesartan, and sometimes requires hospitalization.

– Discontinuation of olmesartan has resulted in clinical improvement of sprue-like enteropathy symptoms in all patients.

• In June 2012, Mayo Clinic researchers published a case series of sprue-like enteropathy associated with olmesartan in 22 patients (Mayo Clin Proc 2012;87:732-8)

ACE Inhibitors vs. ARB’s on Outcomes in Patients with Diabetes

• Twenty-three trials compared ACEIs with placebo or active drugs (32 827 patients) and 13 compared ARBs with no therapy (controls) (23 867 patients). When compared with controls (placebo/active treatment), ACEIs significantly reduced the risk of all-cause mortality by 13% (RR, 0.87; 95% CI, 0.78-0.98), CV deaths by 17% (0.83; 0.70-0.99), and major CV events by 14% (0.86; 0.77-0.95), including myocardial infarction by 21% (0.79; 0.65-0.95) and heart failure by 19% (0.81; 0.71-0.93).– JAMA Intern Med. doi:10.1001/jamainternmed.2014.348

ACE Inhibitors vs. ARB’s on Outcomes in Patients with Diabetes

• Treatment with ARBs did not significantly affect all-cause mortality (RR, 0.94; 95% CI, 0.82-1.08), CV death rate (1.21; 0.81-1.80), and major CV events (0.94; 0.85-1.01) with the exception of heart failure (0.70; 0.59-0.82).

• Both ACEIs and ARBs were not associated with a decrease in the risk for stroke in patients with DM.

• Meta-regression analysis showed that the ACEI treatment effect on all-cause mortality and CV death did not vary significantly with the starting baseline blood pressure and proteinuria of the trial participants and the type of ACEI and DM.

Digoxin in Heart Failure : ACC/AHA Heart Failure Guidelines 2013

Class IIa• Digoxin can be beneficial in patients with

HFrEF, unless contraindicated, to decrease hospitalizations for HF. (Level of Evidence: B)– Digoxin Intervention Group Trial (N Engl J Med

1997;336:525-33)– Doses of digoxin that achieve a plasma

concentration of drug in the range of 0.5 to 0.9 ng/mL are suggested, given the limited evidence currently available

Digoxin and Outcomes?• New digoxin use and risks of death and HF hospitalization,

controlling for medical history, laboratory results, medications, HF disease severity, and the propensity for digoxin use. We also conducted analyses stratified by sex and concurrent β-blocker use. Among 2891 newly diagnosed patients with systolic HF, 529 (18%) received digoxin.

• During a median 2.5 years of follow-up, incident digoxin use was associated with higher rates of death (14.2 versus 11.3 per 100 person-years) and HF hospitalization (28.2 versus 24.4 per 100 person-years). In multivariable analysis,

• incident digoxin use was associated with higher mortality (hazard ratio, 1.72; 95% confidence interval, 1.25–2.36) but no significant difference in the risk of HF hospitalization (hazard ratio, 1.05; 95% confidence interval, 0.82–1.34). – Results were similar in analyses stratified by sex and β-blocker

use.• Circ Cardiovasc Qual Outcomes. 2013;6:525-533

Digoxin after 230 years?• The Editorial by Dr. Opie entitled “Digitalis, Yesterday

and Today, But Not Forever” concludes: “This conclusion is the opposite of what the earlier studies favoring digoxin use in the bygone era of imperfect therapy for HF had found, with the new conclusion that therapy for HF that includes β-blockade and full angiotensin-II modulation dispenses with the need for taking the risks of adding digoxin therapy. The data at our disposal, taking into account the current study, allow us to seriously question the advice on digoxin given by both the current and influential guidelines, European and American.”– Circ Cardiovasc Qual Outcomes. 2013;6:511-513

Aspirin in Patients with Heart Failure• A retrospective cohort study of 1476 patients (mean age

70.4±12.4 years, 63% male) attending a HF disease management program examined aspirin use at baseline and its association with mortality and HF hospitalization. 892 (60.4%) were prescribed aspirin (75mg/day in 92.8%). Median follow-up time was 2.6 [0.8:4.5] years. – Over the follow-up period, 464 (31.4%) patients died. In

adjusted analysis, low-dose aspirin use was associated with reduced mortality risk compared to non-aspirin use (HR=0.58, 95% CI 0.46–0.74).

– Low-dose aspirin use was associated with reduced risk of HF hospitalization compared to non-aspirin use in the total population (adjusted HR=0.70, 95% CI 0.54–0.90).

Statins and Erectile Function?Data presented at the 2014 ACC Meeting in Wash DC• The investigators searched for randomized controlled trials

that examined the effect of statin therapy on erectile function. They identified 11 such trials in which men completed the International Inventory of Erectile Function survey, which consists of five questions, each scored on a five-point scale, where low values represent poor sexual function– a total of 647 men, an average age of 57.8 years and who had

received statins for about 3.8 months.– average LDL-C levels dropped significantly from 138 to 91 mg/dL in

the treated men but were virtually unchanged in control groups.• Journal of Sexual Medicine first published online: 29 MAR 2014 DOI:

Statins and Erectile Function?• Men who took statins had their erectile-

function scores increased by 3.4 points, from 14.0 to 17.4 points—a 24.3% increase. The increase in erectile-function score was about one-third to one-half of that reported with phosphodiesterase inhibitors (PDE-5 inh).– Pluses and Minuses: they improve endothelial

function, which may improve blood flow to the penis; but on the other hand, they lower the level of cholesterol, a precursor of testosterone.

Hepatitis C• An estimated 3 million to 4 million persons in the

United States are chronically infected with HCV, and approximately half are unaware of their status. – These individuals may ultimately progress to advanced

liver disease and/or hepatocellular cancer. However, those outcomes can be prevented by treatment, which is rapidly improving and offers the potential of a cure to more patients than has been previously possible.

– HCV testing is recommended at least once for persons born between 1945 and 1965.

FDA Approval of Jansen’s Simeprevir - Olysio

• Oct 24, 2013 The FDA Antiviral Drugs Advisory Committee voted unanimously (19 to 0) to recommend approval of the investigational protease inhibitor simeprevir (TMC435) administered once daily as a 150 mg capsule with pegylated interferon and ribavirin for the treatment of genotype 1 chronic hepatitis C in adult patients with compensated liver disease, including cirrhosis. The Advisory Committee recommended the approval of simeprevir based on analyses of data from clinical trials in patients who are treatment-naive (QUEST-1 and QUEST-2)or who have failed previous interferon-based therapy (PROMISE).

• FDA Approved 11-22-2013• Cost: $21,221.93/28 X 150 mg caps WAC

Page 56: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Simeprevir - Olysio

• Clinical trials found simeprevir can reduce treatment time in half to 24 weeks. The medicine cured about 80 percent of patients who hadn’t been treated before compared with 50 percent of those who took pegylated interferon and ribavirin. Seventy-nine percent of simeprevir users who failed other treatments were cured compared with 37 percent who took only the older drugs,

Page 57: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Simeprevir - Olysio• For patients infected with genotype 1a HCV, baseline

resistance testing for the Q80K polymorphism may be considered. However, in contrast to using simeprevir to treat a genotype 1a HCV patient with PEG/RBV when the mutation markedly alters the probability of an SVR, the finding of the Q80K polymorphism does not preclude treatment with simeprevir and sofosbuvir, because the SVR rate was high in patients with genotype 1a/Q80K infection (SVR12 rate for cohort 1 was 86% [24 of 28 patients].

• Thus Q80K testing can be considered but is not strongly recommended.– http://www.hcvguidelines.org 2014 accessed 2-3-2014

Sulfa Allergy?• Simeprevir contains a sulfonamide moiety. In

subjects with a history of sulfa allergy (n=16), no increased incidence of rash or photosensitivity reactions has been observed. However, there are insufficient data to exclude an association between sulfa allergy and the frequency or severity of adverse reactions observed with the use of Simeprevir.

Cost vs. Benefit?• “A panel of experts at a recent forum in San Francisco

concluded that the drug offered “low value” for treating most patients, in large part because of its high price. That judgment was based partly on an assessment of clinical and cost-effectiveness prepared by a nonprofit organization that evaluates medical treatments (the Boston-based Institute for Clinical and Economic Review). The group estimated that replacing current care of infected Californians with Sovaldi-based regimens would raise drug expenditures in the state by $18 billion or more in a single year. It said projected savings from reduced medical costs in later years would not come close to offsetting that cost.” – New York Times March 15, 2014

Page 71: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Cost vs. Benefit?

• “The drug will be sold for much less in many other countries. Gilead plans to license three to five Indian drug makers to produce Sovaldi and expects the price to be perhaps $2,000 for six months of treatment through public hospitals and community clinics in India (compared with $168,000 for six months in the United States). Gilead said similar arrangements might be made in 60 low- and middle-income countries. Prices in Europe are high, but not as high as in the United States.”– New York Times March 15, 2014

Page 72: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Cost vs. Benefit?• “What can or should be done to reduce the cost in the

United States? Some experts suggest providing the drug only to patients with advanced liver disease. Others hope that other new drugs in late stages of clinical testing will be approved, adding competition that could help restrain prices. Still others urge that state Medicaid agencies, which cover a big portion of the infected people, negotiate with Gilead for lower prices or find ways to limit the drug’s use when other good options are available. There is no easy way to contain costs as expensive new drugs come along, so all of these strategies will need to be tried.”– New York Times March 15. 2014

2014 AHA/ACC/HRS Atrial Fibrillation Guideline• Little benefit with aspirin: This quote says a lot. "No

studies, with the exception of the [Stroke Prevention in Atrial Fibrillation-1] SPAF-1 trial, show benefit for aspirin alone in preventing stroke among patients with AF.“– urged to question the common practice of using aspirin in

low-risk patients. "aspirin has not been studied in a low-risk AF population"

• AF ablation has been moved to first-line status for both paroxysmal and persistent AF patients. This welcome change aligns these guidelines with those from Europe– AF ablation should not be performed in patients who

cannot be treated with anticoagulants, and AF ablation should not be done with the sole intent of avoiding anticoagulation.

• Increased time to first exacerbation - 187 days vs 145 days (p< 0.001)

• Reduced number of moderate or severe exacerbations – 0.64 vs 0.72 (p=0.002) Requiring oral steroids or antibiotics

• Reduced number of severe exacerbations – 0.09 vs 0.13 (p< 0.001) Requiring hospitalization

• No difference in serious adverse events NEJM 2011;364(12):1093-1103.

Page 103: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

An inhaled corticosteroid combined with a long-acting beta2-agonist is more effective than the individual components in improving lung function and health status and reducing exacerbations in moderate to very severe COPD.

Combination therapy is associated with an increased risk of pneumonia.

Addition of a long-acting beta2-agonist/inhaled glucorticosteroid combination to an anticholinergic (tiotropium) appears to provide additional benefits.

Vortioxetine - Brintellix by Takeda • A Selective Serotonin Reuptake Inhibitor

(SSRI) antidepressant approved for treatment of major depressive disorder (MDD).– a 5-hydroxytryptamine 1A (5-HT1A) agonist, 5-

HT1B partial agonist, 5-HT3 antagonist, 5-HT7 antagonist, and 5-HT transporter protein inhibitor

– net effect of these activities is an increase in the levels of 5-HT, noradrenaline, dopamine, and acetylcholine, and histamine in the ventral hippocampus and medial prefrontal cortex

Page 108: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Vortioxetine - Brintellix

• The half-life of vortioxetine is approximately 66 hours because of the large apparent volume of distribution

• About 98% bound to plasma proteins• Metabolized mainly by cytochrome P450 (CYP 2D6) with

6 total metabolites with little to no antidepressant activity– Vortioxetine and its primary metabolite have been shown to

be substrates and weak inhibitors of CYP2C19, but coadministration studies have not shown clinical significance in humans.

• Vortioxetine has minimal renal clearance, and negligible amounts of the drug found in urine

Page 109: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Vortioxetine - Brintellix

• The labeling for vortioxetine contains the boxed warning regarding suicidal thoughts and behaviors that is required for all antidepressants. Use of antidepressants in the treatment of children, adolescents, and young adults was associated with increases in the risk of suicidal thoughts and behaviors and a trend towards reduced risk in patients 65 years and older.

• All patients will need to be monitored for changes in mental function, behavior, and suicidal ideation.

• Use of antidepressants may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder. Activation of mania/hypomania may occur in patients with major affective disorder.

Vortioxetine - Brintellix

Drug Interactions:• The risk of serotonin syndrome is increased when

vortioxetine is used with other drugs that affect the serotonergic neurotransmitter system (eg, SSRIs, SNRIs, triptans, buspirone, tramadol, tryptophan) – Serotonn syndrome symptoms may include changes in

mental status (eg, agitation, hallucinations, delirium, coma), autonomic instability (eg, tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (eg, tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or GI symptoms (eg, nausea, vomiting, diarrhea).

Page 113: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Vortioxetine - Brintellix

Drug Interactions:• Bupropion: The active metabolites of bupropion inhibit CYP2D6,

the primary metabolizing agent of vortioxetine. Multiple doses of bupropion 150 mg twice daily coadministered with vortioxetine 10 mg once daily increased the steady-state plasma exposure of vortioxetine 2-fold. Reduction in vortioxetine dose by 50% or avoidance of bupropion therapy may be necessary

• NSAIDs: vortioxetine and NSAID,s may both inhibit platelets and increase the risk of bleeding

• Warfarin: vortioxetine is a weak inhibitor of CYP2C9 in vitro, which is known to metabolize warfarin. However, multiple daily doses of vortioxetine 10 mg had no effect on the steady-state pharmacokinetics or pharmacodynamics of warfarin

Page 114: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Vortioxetine - BrintellixDosage:• The recommended starting dose is 10 mg administered orally once

daily without regard to meals. • Dosage should then be increased to 20 mg/day, as tolerated,

because higher doses demonstrated better treatment effects in trials conducted in the United States.

• The efficacy and safety of doses above 20 mg/day have not been evaluated in controlled clinical trials.

• A dose decrease down to 5 mg/day may be considered for patients who do not tolerate higher doses

• The maximum recommended dosage for known CYP2D6 poor metabolizers is 10 mg/day

• Vortioxetine is available as 5, 10, 15, and 20 mg immediate-release tablets Cost: $209.25 for 30 tabs WAC

Vortioxetine - Brintellix

• Abrupt discontinuation of antidepressant therapy can produce discontinuation symptoms (eg, headache, muscle tension, mood swings, sudden outbursts of anger, dizziness, runny nose) during the next week. Some patients experienced these types of symptoms after abrupt discontinuation of vortioxetine 15 and 20 mg/day

Page 116: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Vortioxetine - Brintellix

• CONCLUSION: Vortioxetine has a mechanism of action that is different from other antidepressant medications. The results from the evaluated clinical studies are mixed. Some studies show no benefit compared with placebo, while others did show a benefit. Several of the studies have used duloxetine as an active comparator, but were not designed to compare the efficacy of vortioxetine with duloxetine. Vortioxetine appears to be well tolerated. Its place in the treatment of patients with MDD, who are treatment-naive and non–treatment naive, remains to be documented.

Levomilnacipran -Fetzima• Levomilnacipran is indicated for the treatment of

major depressive disorder (MDD). – Milnacipran is indicated for the management of

fibromyalgia. Levomilnacipran is not approved for the management of fibromyalgia.

• Levomilnacipran undergoes desethylation to form desethyl levomilnacipran by CYP 3A4, approximately 58% of the dose is excreted in urine as unchanged levomilnacipran. N-desethyl levomilnacipran is the major metabolite excreted in the urine and accounted for approximately 18% of the dose.

• The elimination T1/2 is ~12 hours vs. 6-8 hours for milnacipran

Levomilnacipran -Fetzima

CONCLUSION: Levomilnacipran is approved only for the treatment of MDD, while the racemic mixture, milnacipran, is approved only for the treatment of fibromyalgia. There are no head-to-head clinical trials of either of these drugs or against other SNRIs in the treatment of MDD or fibromyalgia. Both drugs are SNRIs and have similar contraindications, warnings, and precautions. Without head-to-head comparisons in studies lasting longer than 11 weeks, the value of this drug is unknown.

Measurement-Based Care• Measurement-based care (MBC) promotes the use of

rating scales or questionnaires to measure symptoms, side effects and adherence at every visit as well as guide tactics to modify dosage and treatment duration. Currently, most clinicians do not routinely use specific measures of depressive symptoms at patient visits. Rather, they tend to use global measures instead of specific symptoms measures.

• Results from the STAR*D study show that the use of MBC may lead to greater remission rates than those seen in efficacy studies for patients with chronic depression. (Am J Psychiatry 2006;163:28-40)

Page 130: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Choice of Antidepressant Medication & Dosing

• Choice of treatment should be guided by:• Patient’s prior response to treatment

• Tolerability

• Psychiatric and medical comorbidity

• Concurrent medications

• Family history of response

• Patient preference

• Cost• Patient education and family involvement play critical roles in

ensuring patient adherence to treatment.

APA Practice Guideline for the Treatment of Patients WithMajor Depressive Disorder 3rd Ed -2010

• To reduce the risk of relapse, patients who have been treated successfully with antidepressant medications in the acute phase should continue treatment with these agents for 4–9 months [I].

• In general, the dose used in the acute phase should be used in the continuation phase [II].

APA Practice Guideline for the Treatment of Patients WithMajor Depressive Disorder 3rd Ed -2010

• When pharmacotherapy is being discontinued, it is best to taper the medication over the course of at least several weeks [I].

• To minimize the likelihood of discontinuation symptoms, patients should be advised not to stop medications abruptly and to take medications with them when they travel or are away from home [I].

Canagliflozin - Invokana

• Canagliflozin is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

• The FDA has asked for five postmarketing studies for the drug including a cardiovascular outcomes trial, an enhanced pharmacovigilance program, a bone safety study and two pediatric studies

• Available as 100 mg and 300 mg tablets– Cost: $277.41/30 tabs WAC both sizes

Page 135: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Canagliflozin - Invokana

Mechanism of Action• Sodium-glucose co-transporter 2 (SGLT2), expressed

in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RTG), and thereby increases urinary glucose excretion.

• Maximal suppression of mean RTG over the 24 hour ‑period was seen with the 300 mg daily dose to approximately 70 to 90 mg/dL in patients with type 2 diabetes in Phase 1 studies.

Page 136: New Drug Update 2013-2014 C. Wayne Weart, Pharm D, FASHP, FAPhA, BCPS Professor of Clinical Pharmacy and Outcome Sciences South Carolina College of Pharmacy

Canagliflozin - Invokana

Patients with Renal Impairment• Canagliflozin increases serum creatinine and decreases eGFR.

– Patients with hypovolemia may be more susceptible to these changes.

– No dose adjustment is needed in patients with mild renal impairment (eGFR of 60 mL/min/1.73 m2 or greater).

– The dose of canagliflozin is limited to 100 mg once daily in patients with moderate renal impairment with an eGFR of 45 to less than 60 mL/min/1.73 m2.

– Canagliflozin should be discontinued or not be initiated in patients with an eGFR less than 45 mL/min/1.73 m2.

– Assessment of renal function is recommended prior to initiation of canagliflozin therapy and periodically thereafter.

Canagliflozin - Invokana

Genital Mycotic Infections:• Canagliflozin increases the risk of genital mycotic

infections. Patients with a history of genital mycotic infections and uncircumcised males were more likely to develop genital mycotic infections. (10-12% in women and 3-4% in men).

Urinary Tract Infections:• 4-6% of patientsIncreased Urination/Polyuria:• 4-6% of patients

AFREZZA®(insulin human [rDNA origin]) Inhalation Powder

• On April 1, 2014 the FDA Endocrinologic and Metabolic Drug Advisory Committee voted 13-1 with one abstention to approve Afrezza for Type 1 diabetics, and 14-0 with one abstention for Type 2 diabetics. – While the FDA isn’t required to follow the panel’s recommendation, it

rarely contradicts it. An official determination is expected by April 15.

• Prior to the meeting FDA staff report worried investors in the stock, as it noted the drug’s potential risk of causing lung infections and bronchial spasms and coughing that caused some patients to stop treatment. Staff also questioned the accuracy of insulin doses in MannKind’s clinical studies. Concern was also raised about the potential for lung cancer with long-term therapy as was seen with Pfizer’s Exubera.
