October 29, 2014 - Pfizer Inc. today announced the publication of a clinical study in the Journal of Clinical Psychiatry showing comparable sexual function in adult patients diagnosed with major depressive disorder (MDD) treated daily with Pristiq (desvenlafaxine) Extended Release Tablets 50mg and 100mg doses versus placebo. Sexual dysfunction is often an issue for patients treated with antidepressants, and Pfizer conducted the study pursuant to a postmarketing requirement by the U.S. Food and Drug Administration (FDA).
“Sexual dysfunction is a common concern for patients treated with antidepressants. This study showed that sexual function was comparable between desvenlafaxine and placebo,” said Dr. Anita Clayton, interim chair, Department of Psychiatry and Neurobehavioral Sciences at the University of Virginia Health System, and lead investigator of the study. “The low potential for sexual dysfunction with desvenlafaxine is encouraging, and physicians and patients would benefit from further study.”
The primary end point of the study showed a statistically significant improvement among patients treated with Pristiq compared to placebo in symptoms of major depressive disorder as measured by the 17-item Hamilton Rating Scale for Depression (HAM-D17) total score over an 8-week period. The HAM-D17 is a validated assessment tool used to rate the severity of a patient’s depressive symptoms. Sexual dysfunction was a secondary end point, and measured using the Arizona Sexual Experiences Scale (ASEX), a validated and reliable patient rated sexual function scale in the United States.
An estimated 33 million to 35 million U.S. adults are likely to experience major depression at some point during their lifetime. The criteria for MDD include having five or more of the symptoms of depression listed below during the same two-week period and representing a change from previous functioning. Depressed mood or diminished interest or pleasure must be among the depression symptoms reported from the following list: depressed mood; diminished interest or pleasure; significant weight loss or change in appetite; insomnia/hypersomnia; psychomotor agitation; fatigue or loss of energy; feelings of worthlessness or excessive/inappropriate guilt; difficulty concentrating; and recurrent thoughts of death.
In this Phase 4, multi-center, randomized, double- blind placebo-controlled study, a total of 924 patients, 18-years or older, with a baseline HAM-D17 score of ≥20, were randomly assigned to Pristiq 50mg/day, Pristiq 100 mg/day or placebo in a 1:1:1 ratio over an 8-week period. The primary efficacy end point for the study was the change from baseline in HAM-D17 total score at week 8. In the primary efficacy analysis, a statistically greater change from baseline was observed in patients receiving Pristiq 50 mg and Pristiq 100mg compared with placebo. The most common treatment emergent adverse events observed were consistent with the known safety and tolerability profile of Pristiq.
Sexual function was assessed using the ASEX Scale. The ASEX was selected over other validated scales because it is a brief but sensitive tool, less burdensome to patients than a more in-depth scale, and has been utilized in previous trials for desvenlafaxine and other antidepressant drugs. It measures five core elements of sexual function (sexual drive, arousal, penile erection/vaginal lubrication, ability to reach orgasm, and satisfaction from orgasm) rated on a six-point Likert scale. A Likert scale is a psychometric scale commonly utilized in research that employs questionnaires. A total score is calculated as the sum of all 5 individual item scores; negative numbers for change from baseline indicate improvement in sexual function.
Incidence of sexual dysfunction was assessed using the ASEX data. In adult outpatients with MDD with baseline sexual activity and at least one post-baseline assessment, effects on ASEX total and item scores were comparable for the Pristiq 50 mg and Pristiq 100 mg groups and placebo. Rates of sexual dysfunction were comparable between each Pristiq dose and placebo at baseline (placebo, 52%; Pristiq 50 mg/d, 56%; Pristiq 100 mg/d, 54%) and at week 8 (placebo, 45%; Pristiq 50 mg/d, 49%; Pristiq 100 mg/d, 47%).
“The treatment and management of MDD in adults can be both complex and challenging for physicians and patients,” noted Dr. Salomon Azoulay, global clinical and medical affairs head, Pfizer Global Established Pharma. “As a science-based company, we continue to study Pristiq in order to provide clinicians with information that can help guide their treatment decisions and positive health outcomes for patients with MDD.”
About Pristiq (desvenlafaxine)
Pristiq, a selective serotonin and norepinephrine reuptake inhibitor (SNRI), is a prescription medication that was approved by the U.S. Food and Drug Administration (FDA) in 2008 for the treatment of MDD in adults. The recommended dose for Pristiq is 50 mg once daily, with or without food. In clinical studies, doses of 50-400 mg/day were shown to be effective, although no additional benefit was demonstrated at doses greater than 50 mg/day and adverse events and discontinuations were more frequent at higher doses.Pfizer Inc.: Working Together for a Healthier World®

Nearly half million apply for U.S. health insurance despite flaws: officials
(Reuters) - Roughly half a million Americans have applied for health insurance through new federal- and state-run exchanges under President Barack Obama's signature healthcare law, an administration official said on Saturday.
That figure comes as problems with the federal marketplace's entry portal serving 36 states, the website Healthcare.gov, have thwarted consumers from shopping for federally subsidized health coverage and drawn derision from Republicans, who oppose the law, popularly known as Obamacare.
The acknowledgement of the number of applicants, late on a weekend evening, appeared to be part of a ramped-up damage control effort by the White House.
Obama's Patient Protection and Affordable Care Act is expected to provide private health coverage to an estimated 7 million uninsured Americans through the new online marketplaces that opened for enrollment in all 50 states on October 1.
But the Healthcare.gov website was hobbled by technical issues - including error messages, garbled text and delays loading pages - that administration officials blame partly on an unexpectedly high volume of 14.6 million visitors in its first several days of activity.
Obama is frustrated by the poor start and told advisers during a recent Oval Office meeting that the administration had to take responsibility for not having the site ready on time, an official said.
"The website is unacceptable, and we are improving it, but the product is good and across the country people are getting access to affordable care starting January 1," one administration official said.
"We are going to work intensely for the next six months to make sure we meet the demand."
Another administration official said that among the roughly half a million applicants, more than half lived in states where the federal government was administering the health exchanges in full or in part.
Official figures from October activity are not due until next month.
Obama is holding a healthcare-themed event at the White House on Monday and will likely address the problems.
Members of his administration plan to travel the country to encourage people in areas with high levels of the uninsured to apply, an official said, and call centers were getting more staff to deal with phone calls from applicants who have trouble getting through online.
As Washington moves on from a 16-day government shutdown that concluded this week, Republicans are also turning up the heat on the administration to address the program's problems. Republicans in the House of Representatives triggered the government shutdown in a failed attempt to defund or delay Obamacare.
Republicans have criticized Health and Human Services Secretary Kathleen Sebelius for declining to appear before an oversight panel to discuss the issue on October 24.

Data center glitch is latest problem in 'Obamacare' rollout
(Reuters) - A data center critical for allowing uninsured Americans to buy health coverage under President Barack Obama's healthcare law went down on Sunday, halting online enrollment for all 50 states in the latest problem to hit the program's troubled rollout.
The data center operated by Verizon's Terremark experienced a connectivity issue that caused it to shut down, affecting the federal government's already problem-plagued online marketplace Healthcare.gov and similar sites operated by 14 states and the District of Columbia, according to the U.S. Department of Health and Human Services (HHS).
Obama administration and company officials could not say how long it would take to fix the connectivity problem.
Separate technical problems that have stalled enrollment on Healthcare.gov since its launch on October 1 are at the heart of a new Republican effort to discredit the healthcare law, also known as Obamacare, largely through congressional investigations to determine what went wrong in building the costly and complicated implementation system.
Health and Human Services Secretary Kathleen Sebelius is due to testify later this week before a House of Representatives committee, while government contractors work around the clock to improve the Healthcare.gov website.
The outage that started in the early hours of Sunday caused the data center to lose network connectivity with the federal government's data services hub, an electronic traffic roundabout that links the online health insurance marketplaces with numerous federal agencies and can verify people's identity, citizenship, and other facts.
Without the hub, consumers are unable to apply online for coverage or determine their eligibility for federal subsidies to help pay for insurance premiums. On Saturday, Sebelius praised the hub's ability to perform complex calculations in quick time as an example of a successful segment of the system.
HHS spokeswoman Joanne Peters said Sebelius spoke with Verizon's chief executive officer on Sunday afternoon to discuss the situation: "They committed to fixing the problem as soon as possible."
The outage was affecting enrollment in all 50 states, as well as Terremark customers not connected with the marketplaces, according to the HHS spokeswoman. She said the data center's network connectivity went down during planned maintenance to replace a failed networking component.
A spokesman for Verizon said the problem would be fixed "as soon as possible."
"Our engineers have been working with HHS and other technology companies to identify and address the root cause of the issue," Verizon spokesman Jeff Nelson said.
The administration has expressed confidence it can fix underlying problems with Healthcare.gov by early December, in time for people to meet a December 15 deadline to enroll in new health plans to receive benefits on January 1. Further delays would jeopardize its ability to enroll as many as 7 million Americans for coverage during Obamacare's first year.
Sebelius, who faces Republican calls for her resignation, will be grilled about her role in the Obamacare rollout on Wednesday before the House Energy and Commerce Committee.
Contractors have already blamed the administration for not conducting enough vital system-wide testing and for a last-minute design change requiring online visitors to set up accounts before window-shopping for insurance. The change is widely blamed for creating early bottlenecks as millions of people flooded the website.
Health officials in Connecticut, one of the 14 states that constructed their own marketplaces, were the first to report on Sunday that potential customers would not be able to complete the sign-up process for some services but could create accounts and search for pricing comparisons.
The Centers for Medicare and Medicaid Services, the HHS agency responsible for the federal system, told Connecticut officials about the outage and gave no indication of when the data services hub would be functioning again, said a spokeswoman for Access Health CT, the Connecticut exchange.
