Here’s a list of compiled links providing information on Pristiq. These links include info from my blog and others.
Done deal: Pfizer buys Wyeth for $68 billion
The New York Times puts it this way:
Funny the writers decided to add that. A year ago, that clause would have never been considered yet alone thought of.
Pfizer isn’t doing badly; in fact, despite the credit crunch, they’ve been able to snag $22.5 billion in loans since they also have $26 billion cash on hand. The NYTimes also reports that this merger would be the biggest since AT&T and BellSouth merged back in March 2006. But of course, with mergers always come layoffs. And what a time to have layoffs. Pfizer today announced that they’ll be cutting 8,000 jobs.
But as I said in a previous post, Pfizer’s biggest challenge is get some pipeline products out to market soon since some of the patents on their big names (ie, Lipitor) are expiring soon. Don’t hold me to this but I think Wyeth has a bit more sitting in their pipeline, hence why the merger would make sense. But I hope Wyeth can produce a new blockbuster drug for Pfizer otherwise Pfizer’s really going to be hurting for money. Especially since Wyeth’s best-selling drug, Effexor, is now generic and Pristiq isn’t completely cutting it.
Pfizer may be buying Wyeth
Is Wyeth being hurt by the failing economy? I’m not so sure but Pfizer may be buying up Wyeth for up to $60 million. According to news reports, this could help the pharmaceutical giant by bringing in some of Wyeth’s brand name products while many of Pfizer’s own manufactures (think Lipitor) go generic. However, it could also be a drawback as one of Wyeth’s biggest sellers—our favorite antidepressant Effexor (venlafaxine)—has gone generic. Also, Pfizer doesn’t have the best track record of buying up other companies and turning them into blockbuster gold. Should be interesting to see what happens in the next few years if the deal does go through.
Pristiq's side effects: Too close to Premarin and Prempro for comfort?
Back in January 2007, I’d mentioned that Wyeth was not only seeking to market Pristiq (desvenlafaxine) for depression but also for the use of vasomotor symptoms in menopausal women.
I just learned that Wyeth produces two major menopause drugs, Premarin and Prempro, that allegedly has produced hormones causing cancer in more than 5,000 women. This added up to a loss of 40 million users and $1 billion annually.
With Effexor going generic in 2 years and the introduction of Pristiq to the market, Wyeth hopes to lure some of those customers back and net an annual $2 billion. However, serious questions linger about Pristiq’s side effects in menopausal women.
Why did two women in the study group taking Pristiq have heart attacks
and three need procedures to repair clogged arteries compared with none
taking placebo? How can Wyeth assure long term safety when 604 of the
2,158 test subjects took Pristiq for only six months and 318 for a year
or more? And what about serious liver complications seen in the studies?
Martha Rosenberg, reporting on Pristiq’s use as a menopausal drug, culled comments from CafePharma’s message boards and found one thread rife with mixed comments on the new drug. From an Anonymous commenter:

John Grohol interviews Wyeth's VP of Medical Affairs on Pristiq
Dr. Grohol interviewed Dr. Phil Ninan, Wyeth’s VP of Medical Affairs on Pristiq, its efficacy, and surrounding issues. It was quite an interesting interview (and long) but here are some highlights that I chose to comment on. I’ll be making some comments in between Dr. Ninan’s answers due to the extensive length. Some parts of the answers have been truncated.

Pharma's "me-too" drugs face skeptical docs and health insurers
As patents expire on a variety of drugmakers’ moneymakers, pharma companies have gone to great lengths to structurally reinvent the successful drugs then tout the benefits that differ from their predecessors.
Case in point — Johnson & Johnson’s Invega. Invega is the successor to the popular antipsychotic drug, Risperdal, and competitor to AstraZeneca’s widely used antipsychotic Seroquel. Scott Hensley at The Wall Street Journal’s Health Blog (WSJ) reports that Risperdal is going generic in June. Gianna at Beyond Meds recently said it will not. According to the Dow Jones Newswires (DJN), these “junior” drugs face skepticism from health insurers and doctors. California-based Kaiser Permanente and Minneapolis-based UnitedHealth Group Inc. (UNH) are example of companies that have somewhat discouraged use of the drug. Kaiser doesn’t cover Invega at all, and members of UNH are required to pay higher copays for the brand name. The wire reports New York-based psychiatrist Jeffrey Lieberman wasn’t “buying it” the difference between Invega and Risperdal.
Invega is “basically a me-too drug, and the company hasn’t done the studies that would be required to really distinguish it,” Lieberman, chairman of the psychiatry department at Columbia University’s medical school told Peter Loftus of Dow Jones Newswires.
The blog also quotes Daniel Carlat from the The Carlat Psychiatry Report.
Dan Carlat, a psychiatrist and a tough critic of Invega, wrote that J&J’s “marketing team apparently missed the fact that the word in the English language that sounds most like “Invega” is “inveigle,” meaning “to entice, lure, or ensnare by flattery or artful talk or inducements.’ ” He asked doctors: “Will you be doing your patients a favor by taking the plunge? Or will you simply be giving them the same wine in a fancier bottle?”
Even J&J’s Group Chairman of Pharmaceuticals, David Norton, admitted that Invega is a tough sell.
“We need to do a better job at drawing a differentiation in a difficult-to-treat population.”
So far, Invega sales have been incredibly disappointing compared to the Risperdal blockbuster.
Wyeth (antidepressant Effexor XR cum Pristiq) and Shire (ADHD drug Adderall XR cum Vyvanse) face the same uphill battle. Wyeth’s Effexor faces generic competition from Teva Pharmaceuticals despite efforts to halt generic sales of the drug and the patent on Shire’s Adderall is set to expire next year.
Hensley, in his analysis, raises a question in which the answer remains to be seen:
Cheap generics abound to treat a broad assortment of illnesses these days. What’s the point, the critics ask, of paying more for drugs that are at best only slight improvements over tried and true medicines available at bargain prices?
It’s something that I’ve questioned myself.
In an attempt to have the “me-too” drugs compete with its derivative, both Wyeth and Shire are slashing their prices, or as the DJN reported, “emphasizing improved dosing for the newer drugs.” Although Pristiq’s efficacy comes at higher doses, it’s being priced 20 percent lower than Effexor.
[Deutsche Bank pharmaceutical analyst Barbara Ryan] thinks the odds of
Pristiq’s success are slim because it appears to offer few benefits
beyond those of Effexor.
That remains to be seen. So far, a few patients have commented on my blog that Pristiq has already begun to help them. I haven’t seen any DTC ads for Pristiq so I can only assume that drug reps are doing a fine marketing job at selling the different benefits of the drug to doctors.
Vyvanse, on the other hand, is looking promising for Shire, already having 7 percent of U.S. ADHD drug prescriptions. Chief Executive Matthew Emmens says the drug is chemically different from Adderall (aren’t they all?) and has better pricing. Shire expects to beat Adderall’s 26 percent peak market share. Seems like a lofty goal to me.
As for Invega, J&J is currently seeking FDA approval to use the drug for bipolar disorder and not just treatment for schizophrenia. It is also l0oking to get approval for an injectable Invega XR.

Poor Wyeth — New drug delayed in FDA approval
Wyeth Pharmaceuticals just can't seem to catch a break. The company is not only increasingly worried that it will lose a large chunk of its revenues to generic competition, it also faces the ongoing threat that its pipeline is starting to go dry. A further delay in the approval of its postmenopausal osteoporosis drug has become one more nail in the pharma company's coffin.
The drug, bazedoxifene, has had a hard time getting approval from the FDA since April 2007. The FDA is concerned about bazedoxifene's effects on causing myocardial infarctions or blood clots.
This is some pretty disheartening (to say the least) news considering that Effexor will soon be going generic and Pristiq has received some less-than-stellar reviews.
My official position on pharmaceutical companies and psychotropic meds
In previous posts, perhaps I’ve come off a little bit as “I hate Big Pharma.” I did. For a while.
I’m not in love with pharmaceutical companies either. I’ve quoted it before but “to whom much is given, much is required.” As a result of accumulating knowledge through reading and research, I know a whole lot more about pharmaceutical companies, the treatment options they put out there, and what lengths they go to get those treatments out there. Most of the things I read are negative. Much of what I’ve said is negative. Perhaps “ignorance is bliss.” My husband said this recently:
“The Internet is the great bitching ground. No one’s going to talk about how great medication is. Everyone’s going to go on and just bitch about side effects and bad experiences.”
I agree. “Effexor really helped me feel better today” doesn’t make for an interesting blog post. No one pays attention to medication when it’s working, however, everyone will complain if something is going wrong. The most “positive” drug comments I’ve seen are on my seemingly “negative” posts from people who are being helped by a drug.
Take, for instance, the following comment from Suffering:

Wyeth Pushing Pristiq Hard
The Wall Street Journal reports that Wyeth, desperate to make money off of its Effexor XR-knockoff, Pristiq, says it will slash the antidepressant at a 20% discount compared to Effexor’s price. The price slash, CNN money reports, is a result of less-than-impressive clinical trial data on Pristiq’s “safety and effectiveness.”
Wyeth SVP Joe Mahady told analysts that Pristiq will sell for a flat $3.41 per tablet for both mid- and high-dose, Dow Jones Newswires’ Peter Loftus reports.
Wyeth, apparently, has done this in the past. Back when it was known as American Home Products, the company slashed its price on Protonix, its heartburn drug, to compete with AstraZeneca’s Prilosec. The drug generated $1.9 billion in profits for Wyeth last year. CNN Money reports that Teva Pharmaceuticals and Sun Pharmaceuticals began selling the generic version of the drug and handily cut into Wyeth’s profits: the company reported a 4.6% decline in profit and a 66% drop in sales for the drug for the first-quarter. What will happen with Pristiq remains to be seen. I’m not sure that doctors in 2010 will want to dole out prescriptions for Pristiq when they can save patients—and insurance companies—money by prescribing what will then be known as venlafaxine. WSJ also notes:
A month’s supply of sertraline (Pfizer’s old hit Zoloft) or fluoxetine (Lilly’s Prozac) goes for 50 cents a day at drugstore.com.
$3.41 or $0.50 per tablet. It wouldn’t surprise me if some insurance companies choose to exclude Pristiq from its list of covered drugs. Regardless, Wyeth expects sales of the drug to exceed $1 billion in its first year.
The drug will hit the shelves in May.
Wyeth reps no like Pristiq
Oof. I'm just starting to read The Carlat Psychiatry Blog and stumbled upon this post about Wyeth drug reps trashing Pristiq. Wow. Carlat pulled an excerpt of a Wyeth rep mocking Pristiq's new marketing slogan: "People, Passion, Performance… Pristiq!"
"PEOPLE – 1/2 of you will be gone in less than 27 days
PASSION – There is no passion now, but for those that remain with Wyeth, we will bribe the passion out of you by taking you to Vegas for 4 days.
PERFORMANCE – You thought it was hard to reach your performance incentive before? Wait until 2nd quarter
PRISTIQ – Good luck selling both Effexor XR and Pristiq at the same time. So Dr., would you like to hear about my antidepressant that has been around for 12 years, with proven efficacy with the ability to titrate the dose as need to better care for each patient's needs that will have generic competition in 4 months, or would you like to hear about my brand new antidepressant with one dose, less indications and less evidence of efficacy? You want me to choose, let me check with my bonus plan to see which one pays more."
If this is the typical attitude within the Pristiq sales force, Wyeth may end up a little shy of the blockbuster they were hoping for!
I couldn't have said it better myself.
