EU regulator rejects Xyrem as fibromyalgia treatment

 22 Mar 2011

The European Medicines Agency (EMA) has decided not to approve sodium oxybate (brand name Xyrem) as a treatment for fibromyalgia.
Xyrem is an oral solution that is currently used to treat some cases of the sleep disorder narcolepsy in adults.
However, the EMA's Committee for Medicinal Products for Human Use (CHMP) has made the decision not to recommend it for patients with fibromyalgia, a chronic condition that can cause widespread muscle pain. The drug is classed as a controlled substance in the US because of its potential for abuse.
It is thought that as many as one in every 50 people may suffer from fibromyalgia, but there is currently no approved medication for the long-term condition in Europe.
Professor Iris Loew-Friedrich, chief medical officer at pharmaceutical firm UCB, commented: "Upon discussions and following oral explanation with the CHMP, we have to accept that Xyrem in fibromyalgia syndrome will not be recommended for approval in the EU near-term.
"We are very disappointed with the CHMP decision given the significant unmet medical need in fibromyalgia syndrome in Europe today and the consistently positive phase-III clinical trials with Xyrem in the indication."
The decision comes after results from a second phase-III clinical trial of Xyrem in patients with fibromyalgia were presented at the annual meeting of the American Academy of Pain Medicine.
Results from the trial, which involved 376 patients at more than 100 centres in the US and Europe, showed that 51.4 per cent of patients who took 6g per night and 42 per cent of patients who took 4.5g per night benefited from at least a 30 per cent reduction in pain.
In contrast, just 26.8 per cent of patients who took a placebo (dummy treatment) experienced similar levels of pain relief.
A spokesman for Arthritis Research UK commented that there were few effective drugs available to treat fibromyalgia but added that regulators had to be sure that any new drugs were both effective and appropriate.

United States Court of Appeals

 Argued and Submitted March 9, 2011 — Seattle, Washington.
Cynthia Coleman seeks disability insurance benefits from the Commissioner of Social Security ("Commissioner"). The administrative law judge ("ALJ") determined that Coleman has the residual functional capacity to perform sedentary or light work, so long as she can switch between sitting, standing, and walking at least briefly every hour. Based on testimony provided by a vocational expert ("VE") that Coleman could perform three specified occupations, the ALJ then held that Coleman could perform work that exists in significant numbers in the economy. He therefore denied benefits.
Coleman filed suit in district court, contending that the ALJ erred in two ways. First, Coleman faulted the ALJ for disbelieving her testimony of severe pain on the grounds that her fibromyalgia did not result in certain physical symptoms and that Coleman failed to lose weight as treatment for her obesity.
1. The ALJ relied on the absence of objective physical symptoms of severe pain as a basis for disbelieving Coleman's testimony regarding her symptoms. He erred insofar as Coleman's pain is related to her fibromyalgia, which is a "disease that eludes [objective] measurement."  He also erred by holding, in the middle of a discussion of Coleman's obesity, that her "failure to lose weight reflects on her credibility."
Although we find these errors troubling, we conclude that they were harmless. "[T]here remains substantial evidence supporting the ALJ's conclusions on credibility,"  including Coleman's failure to follow repeated medical recommendations that she treat her pain with exercise and increased activity levels. The ALJ's errors therefore "do not negate the validity of [his] ultimate credibility conclusion" or his resulting determination of Coleman's residual functional capacity.

High risk of compulsive disorders linked to dopamine-mimic drugs, Mayo confirms

Typically prescribed for Parkinson’s, restless legs syndrome, fibromyalgia, depression

A Mayo Clinic study has verified earlier findings that harmful compulsive / impulsive behaviors such as binge eating, spending, computer use, and gambling affect one in four people taking a “medium dose” of a dopamine agonist drug such as pramipexole/Mirapex or ropinirole/Requip.

These drugs act like or mimic the chemical messenger dopamine – “stimulating the reward pathways in the brain.” They are FDA-approved for treatment of Parkinson’s disease symptoms (associated with the death of the nerve cells in the brain that make dopamine) and restless legs syndrome. They are also often prescribed off label for fibromyalgia and depression.

Risk of harmful behaviors increases with higher doses - up to one in three, according to Mayo, so patients and their families should be made aware in order to catch behavioral problems early before they cause harm. Reducing or stopping the medication usually resolves the problems, the researchers have found. But this can also involve sometimes severe withdrawal symptoms.

Pill-free-pain-relief

Chronic pain sufferers may eventually be able to put away the ibuprofen. Just like the song, a new University of Florida study suggests some “good vibrations” take away the pain. UF researchers produced pain by applying heat to the arms of study participants. They followed that pain with stimulating vibrations to block the heat related pain sensations. Researchers say the vibrations reduced the pain sensations in people by 44%. Experts consider this potential new treatment for pain similar to traditional touch therapies already in use.
Dr. Roland Staud/UF pain researcher: “Some forms of massage are very strongly touch related and not painful and they may provide analgesic relief to individuals in pain.”
The study marks the first time a non-painful stimulus was shown to actually provide a pain relieving effect for fibromyalgia patients. Researchers say those who suffer from conditions like fibromyalgia could some day benefit from this kind of treatment, and it could provide an alternative for those who seek treatment from chronic pain.
Dr. Roland Staud/UF pain researcher: “It is not associated with great cost and great risk to the individual as well as the person who provides these treatments.”
Experts say more than 75 million people suffer from chronic pain the United States.

European Medicines Agency decided against Xyrem (sodium oxybate)


Adrienne Dellwo, March 21, 2011
The European Medicines Agency has decided against recommending Xyrem (sodium oxybate) for treating fibromyalgia in adults. To date, the European Union doesn't have any medications approved for fibromyalgia.
Xyrem is approved in both the EU and the U.S. for narcolepsy and cataplexy (a narcolepsy symptom.) The U.S. FDA rejected this medication as a fibromyalgia treatment in October 2010, citing concerns over safety because it's similar to the date-rape drug GHB.
In clinical trials, Xyrem has been shown to improve the quality of stage-four sleep in fibromyalgia. Disrupted deep sleep is believed to be a primary contributor to symptoms of this illness and may play a role in its pathogenesis.

Sodium oxybate reduces pain, fatigue, and sleep disturbance and improves functionality in fibromyalgia: results from a 14-week, randomized, double-blind, placebo-controlled study

14 March 2011.
This 14-week, phase 3, double-blind, randomized, controlled trial evaluated sodium oxybate (SXB) 4.5 and 6g per night versus placebo in patients with fibromyalgia (FM). SXB is the sodium salt of γ-hydroxybutyrate (GHB). GHB is an endogenous compound, synthesized from γ-aminobutyric acid (GABA) and found broadly in the central nervous system and body. Among 548 randomized patients, a 30% reduction in pain was experienced by 54.2% and 58.5% of patients treated with SXB 4.5 and 6g, respectively, versus 35.2% for placebo with a 100-mm Visual Analog Scale (VAS) (P<0.001 for both comparisons). Relative to placebo, both SXB doses significantly reduced fatigue (with a 100-mm VAS; P<0.001) and sleep disturbance (with the Jenkins Sleep Scale; P<0.001), and resulted in significant improvements in function as measured by the FM Impact Questionnaire (P=0.003 and P=0.001 for 4.5 and 6g per night, respectively). On the Short-Form 36 Health Survey, SXB-related improvement was significant on the Physical, but not the Mental, Component Scale. The proportion of patients who reported a global improvement of “much” or “very much” better on the Patient Global Impression of Change was significantly greater in both SXB groups versus placebo (P<0.001). Headache, nausea, dizziness, vomiting, diarrhea, anxiety, and sinusitis were the most commonly reported adverse events, with an incidence at least twice that of placebo. These results expand the evidence from previous clinical trials suggesting that SXB is effective and safe in FM.

Pico-Tesla receives ISO certification for "Magneceutical Therapy"

Pico-Tesla, The Magneceutical® Company, has received the International Organization for Standardization (ISO) 13485:2003 certificate for the "design, development, production, manufacture and distribution of resonator systems that generate a low-level electromagnetic field for the therapeutic treatment of disease."
ISO 13485:2003 specifies requirements for a Quality Management System whereby a company must demonstrate its ability to provide medical devices and related services that consistently meet the highest quality standards related to the clinical needs of patients and healthcare providers. The certification satisfies Health Canada as a pre-requisite for medical device distribution into Canada, and is also aligned to meet the requirements to the European Medical Device Directive (MDD) 93/42/EEC as amended by 2007/47/EC, to place the CE mark on its products. The certification is a significant step in Pico-Tesla demonstrating conformance to medical device safety and effectiveness requirements, thus strengthening the Company's ability to enter worldwide markets.
"Receiving the ISO 13485 certification bears strong witness to the significant progress we are making toward establishing the clinical application of Magneceutical® Therapy for Parkinson's and other difficult-to-treat diseases," said Allen Braswell, CEO of Pico-Tesla.
"There is one thing that has stayed in my mind since getting involved with this opportunity. That is, to be so driven and committed to quality in such early stages of your product development is not a typical behavior of many companies, whether they are big or small. That commitment driven from the top can only bring continued success!" said Lynette Makowski, Principal Consultant, Achieving RA/QA Compliance LLC, a Regulatory and Quality Expert in the Medical Device Industry.
Pico-Tesla's Magneceutical® Therapy is currently in clinical trials to determine its effectiveness for improving the signs and symptoms of several diseases, including  fibromyalgia.

Eli Lilly and Cymbalta

Eli Lilly appears perilously perched on the precipice of a patent cliff. A plummet could result in revenue falling for at least the next two years, and loss of more than 75% of sales within the next 7 years. Worse yet, there’s no parachute of freshly approved drugs to replace this revenue. Lilly’s perch is perhaps the best example of the crisis faced by much of the pharmaceutical industry faces. However, it’s not the end of the world. Even acrophobic investors should take a closer look at patent expiration dates before abandoning hope of possible replacements for this revenue.
Unlike an Abbott or Johnson & Johnson, Eli Lilly is nearly a pure pharmaceutical company, without a significant medical devices or consumer business segment. Eli Lilly has a focus on neuroscience (40.8% of 2010 revenue), endocrinology (26.6%), oncology (16.2%), and cardiovascular drugs (9.4%). Other pharmaceutical segments are 0.9% of revenues, and animal health makes up the remaining 6.0% of revenues. Lilly’s bestselling drug is the schizophrenia treatment Zyprexa, which begins the flood of U.S. patent losses later this year. The next highest seller at $3.5 billion and 15% of revenues is Cymbalta, used to treat depression and fibromyalgia, and is on patent until at least June 2013. http://seekingalpha.com/article/258092-how-eli-lilly-will-face-patent-expirations

European Medicines Agency recommend against Xyrem for fibromyalgia

UCB (UCBJF) recently reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended against the approval of Xyrem for the treatment of fibromyalgia syndrome in adults.
We note that Xyrem is already marketed in the European Union (EU) for the treatment of narcolepsy with cataplexy in adults. UCB markets the drug in the EU under a license from Jazz Pharmaceuticals Inc. http://www.zacks.com/stock/news/49378/UCB+Faces+Setback

Sodium oxybate -- a GABA derivative

Abstract 

This 14-week, phase 3, double-blind, randomized, controlled trial evaluated sodium oxybate (SXB) 4.5 and 6g per night versus placebo in patients with fibromyalgia (FM). SXB is the sodium salt of γ-hydroxybutyrate (GHB). GHB is an endogenous compound, synthesized from γ-aminobutyric acid (GABA) and found broadly in the central nervous system and body. Among 548 randomized patients, a 30% reduction in pain was experienced by 54.2% and 58.5% of patients treated with SXB 4.5 and 6g, respectively, versus 35.2% for placebo with a 100-mm Visual Analog Scale (VAS) (P<0.001 for both comparisons). Relative to placebo, both SXB doses significantly reduced fatigue (with a 100-mm VAS; P<0.001) and sleep disturbance (with the Jenkins Sleep Scale; P<0.001), and resulted in significant improvements in function as measured by the FM Impact Questionnaire (P=0.003 and P=0.001 for 4.5 and 6g per night, respectively). On the Short-Form 36 Health Survey, SXB-related improvement was significant on the Physical, but not the Mental, Component Scale. The proportion of patients who reported a global improvement of “much” or “very much” better on the Patient Global Impression of Change was significantly greater in both SXB groups versus placebo (P<0.001). Headache, nausea, dizziness, vomiting, diarrhea, anxiety, and sinusitis were the most commonly reported adverse events, with an incidence at least twice that of placebo. These results expand the evidence from previous clinical trials suggesting that SXB is effective and safe in FM.

Dangers of Paracetamol, Acetaminophen


Blogger's Note:
I thought long and hard about including this in the blog, but decided the dangers of Paracetamol (Acetaminophen, Tylenol), even in therapeutic dosage, are not as well known as they should be.


Paul Cassell
March 08, 2011


A psychiatrist admitted medics at Prospect Park Hospital gave too much medication to a suicidal woman who was later found dead after taking an overdose.
Dr Giovanni Borghini made the frank confession at an inquest into the death of Bridget Proctor at Reading Civic Centre last Tuesday, to the amazement of Mrs Proctor’s daughters Suzanne and Beverley.
The 59-year-old was found dead by a care team from the Tilehurst hospital with several packets of medication by her side in the bedroom of her home in Shilling Close, Tilehurst, on Thursday, April 1, last year.
The inquest heard she had been given two weeks’ worth of medication, predominantly paracetamol, from staff at Prospect Park instead of three days. A failure in communication meant she was given her full allocation.
Giving evidence, Dr Borghini said: “I must say in this case the initial plan was to give her no more than three days of medication and hand over the rest of the supply to the home treatment team.
“The reason why that hasn’t happened is because of a mistake for which I take full responsibility.”
Dr Borghini admitted it was the only mistake he had made in his career and what had happened had reflected on him, the staff and the hospital. He added that lessons had been learned to ensure this could never happen again.
The inquest heard Mrs Proctor had suffered with fibromyalgia, a muscle pain common with psychiatric conditions such as depression and anxiety and stress-related disorders such as post-traumatic stress disorder. Dr Borghini explained there was no known cure for the condition and it was generally treated with painkillers.
He confirmed that Mrs Proctor had suffered with depression for many years and was on a range of medication.
In 2000 Mrs Proctor took a large overdose of prescribed medication and spent time at Prospect Park. After a period of review doctors had no major concerns and she was discharged.
Last March she told her family she was “considering ending it all” and was readmitted to the hospital, where she remained for two weeks during which time she underwent treatment and observation.
Doctors agreed she could be discharged early and provided her with two weeks’ worth of medication, having intended to give her enough for three days and arrange for the rest to be administered on a daily basis by the home care team.
A toxicology report revealed Mrs Proctor had a high level of paracetamol, along with antidepressant codine and lamotrigine, an antiepileptic drug used to treat bipolar disorder.
Blood tests further revealed the paracetamol had most likely caused liver failure.
Recording a narrative verdict, the coroner Peter Bedford said Mrs Proctor died from aspiration pneumonia caused by a combination of toxicity from the deliberate digestion of codine, lamotrigine and paracetamol against a background of depression.
He added she had been mistakenly given two weeks medication even though she remained a potential risk of taking an overdose and “an opportunity had been presented to her” to take her own life.

Pfizer Touts New Drug for Fibromyalgia (Lyrica), Critics Warn Consumers

By Shaun Hittle
Pfizer’s new television commercial for the medication Lyrica, features a middle-aged woman who says that her Fibromyalgia (FMS) is real and that she can now live without pain thanks to the medication.
The advertisement for the first FDA approved medication for Fibromyalgia is aimed at making two arguments: that Fibromyalgia is a real condition, and that Lyrica can lessen its symptoms.
Some critics, however, still argue that Fibromyalgia is not a real medical condition and that consumers need to be skeptical of claims made by pharmaceutical companies.
As defined by the National Fibromyalgia Research Association, Fibromyalgia is a pain disorder characterized by sleep problems and pain and stiffness in numerous sites of the body. Estimates regarding the prevalence of this illness vary, but advocacy groups put the total number of sufferers for FMS at roughly six million in the US.
While the condition is accepted by insurance companies and well-known medical organizations, controversy regarding the existence of the disease still exists. In a recent NY times article, Dr. Frederick Wolfe, who authored the 1990 paper that was the first to establish parameters for FMS, was quoted as refuting his earlier claims that FMS was a real illness. “Some of us in those days thought we had actually defined a disease, which this is clearly not,” said Wolfe in the article.
However, as sales for the drug soar, the public and many in the medical community seem to be buying both of Pfizer’s arguments. Fourth quarter sales as reported by Pfizer for Lyrica, which was approved for the treatment of FMS in the summer of 2007, totaled $564 million; a 60 percent increase from the previous quarter, and annual sales of Lyrica totaled $1.8 billion in 2007 (Lyrica is also used for other medical conditions but Pfizer does not detail sales in terms of reason for prescribing).

Trial Results
In clinical trials for Lyrica, patients experienced a decrease in pain by an average of two points on a ten point scale, compared to an average of one point for placebo, and 30 percent of patients reported a pain decrease by half, compared to 15 percent taking placebo.
Despite these results and FDA approval of Lyrica, patient and consumer advocates argue that consumers need to be cautious about claims made by the local pharmaceutical giant.
Dr. Larry Sasich, a pharmacologist at the Lake Erie College of Osteopathic Medicine (LECOM) and former employee of the consumer watchdog, Public Citizen, warns the public that the information they get in 30 second TV commercials is not the entire story when it comes to a drug, its side effects, or its effectiveness.
“People need to have more information,” said Sasich, noting that physicians should be spending more time reviewing the complicated clinical trials and determining their effectiveness. This, according to Sasich, will provide a buffer between the pharmaceutical industry’s claims and more concrete scientific data and research.
But the bottom line for those suffering from FMS, is that the drug’s approval means some hope for alleviating the symptoms.
Sharon Waldrop, President of the Fibromyalgia Association of Michigan, says that her organization welcomes the new drug and hopes other medications might also soon be approved for the illness. “Finally there is a medication that is specifically shown to help treat pain and disturbed sleep patterns patients experience with fibromyalgia,” said Waldrop.
Pfizer’s advertising track record
For those embracing Pfizer’s claims that Lyrica can treat fibromyalgia, a closer look at Pfizer’s track record regarding their advertising of medications may cause consumers to proceed with caution when deciding whether or not to start taking Lyrica.
Consumer’s International, an international consumer watchdog, has compiled a long list on their website detailing Pfizer’s past history of claims by consumers and industry professionals about false and inaccurate advertising. Included in this list is Pfizer’s guilty plea for falsely marketing the epilepsy drug, Neurontin, for off label uses and Pfizer’s claims about Zoloft’s ability to reduce the likelihood that patients would harm themselves, though actual studies showed the opposite.
Lynne Matallana, President of the National Fibromyalgia Association and a sufferer of FMS, says that she does not have concerns about Pfizer’s advertising or the process by which Lyrica was tested. “It a very rigorous process,” said Matallana regarding the required FDA trials.
For those suffering from FMS and for Pfizer, Dr. Sasich’s recommendation for consumers wanting to try new medications might be difficult to follow: avoid using any new drug until it’s been on the market for at least seven years.
Pfizer Spokes-person Stephen Borboroglu, however, con- tends that Lyrica has already been used by seven million patients worldwide since its first approval by the European Union in 2004. “Numerous credentialed experts in the filed have presented data on Lyrica’s efficacy and safety in several peer-reviewed forums…” said Borboroglu, further explain- ing Pfizer’s stance that Lyrica is a safe and effective medication.
Sasich’s statement also gets a strong reaction from Matanalla: “That’s insane…The large majority of people are not going to wait seven years,” Matanalla said

Improvement in Fibromyalgia Pain Scale Quantified

A two-point improvement on the Brief Pain Inventory represents the minimum clinically important difference for patients with fibromyalgia pain, corresponding to a 30 to 35 percent improvement from baseline, according to a study published online Feb. 10 in Arthritis Care & Research.


TUESDAY, March 8 (HealthDay News) -- A two-point improvement on the Brief Pain Inventory (BPI) represents the minimum clinically important difference (MCID) for patients with fibromyalgia pain, corresponding to a 30 to 35 percent improvement from baseline, according to a study published online Feb. 10 in Arthritis Care & Research.
Philip J. Mease, M.D., of the University of Washington School of Medicine in Seattle, and colleagues used data from four studies evaluating duloxetine as a treatment for fibromyalgia. They estimated the MCID for the BPI average pain item score and the BPI severity score by anchoring them against the Patient Global Impression of Improvement scale.
The researchers determined that an approximately two-point improvement on both the BPI average pain item and severity scores represented the MCID. These MCIDs corresponded to a 30 to 35 percent improvement in baseline pain in both scores.
"These findings may be beneficial for use in designing clinical trials in which the BPI is used to evaluate improvements in pain severity," the authors write.
The study received financial support from Eli Lilly and Company and Boehringer Ingelheim GmbH

Droxidopa, Northera, and Chelsea Therapeutics

CHARLOTTE, N.C. (AP) - Chelsea Therapeutics International Ltd. reported a wider fourth-quarter loss Wednesday as it continued development of its hypotension drug candidate Northera.
Chelsea Therapeutics does not have any products on the market, and it did not report any revenue. The company is preparing to file for Food and Drug Administration approval of Northera, and hopes to launch the drug in early 2012.
Northera is designed to treat neurogenic orthostatic hypotension, which is a drop in blood pressure on standing. The FDA plans to conduct an expedited six-month review of the company's marketing application, and if the drug is approved, it will receive extended market exclusivity.
Chelsea Therapeutics said its research and development costs climbed to $10.2 million from $4 million. It said development of Northera, along with initial manufacturing and validation of the active ingredient in the drug, and a mid-stage trial of a rheumatoid arthritis drug were the causes of the increase in spending.
The active ingredient in Northera is droxidopa. Chelsea Therapeutics is also studying droxidopa as a treatment for fibromyalgia, a chronic disease that causes muscle pain and fatigue.

ACUPUNCTURE: Effects of acupuncture on patients with fibromyalgia: study protocol of a multicentre randomized controlled trial

Fibromyalgia is a multidimensional disorder for which treatment as yet remains unsatisfactory. Studies of an acupuncture-based approach, despite its broad acceptance among patients and healthcare staff, have not produced sufficient evidence of its effectiveness in treating this syndrome.

The present study aims to evaluate the effectiveness of individualized acupuncture for patients with fibromyalgia, with respect to reducing their pain and level of incapacity, and improving their quality of life.Methods/designRandomized controlled multicentre study, with 156 outpatients, aged over 17 years, diagnosed with fibromyalgia according to American College of Rheumatology criteria, either alone or associated with severe depression, according to the criteria of the Diagnostic and Statistical Manual for Mental Disorders. The participants will be randomly assigned to receive either "True acupuncture"or "Sham acupuncture".

They will be evaluated using a specific measurement system, constituted of the Fibromyalgia Impact Questionnaire and the Hamilton rating scale for depression. Also taken into consideration will be the clinical and subjective pain intensity, the patient's family structure and relationships, psychological aspects, quality of life, the duration of previous temporary disability, the consumption of antidepressant, analgesic and anti-inflammatory medication, and the potential effect of factors considered to be predictors of a poor prognosis.

All these aspects will be examined by questionnaires and other suitably-validated instruments. The results obtained will be analysed at 10 weeks, and 6 and 12 months from the start of treatment.DiscussionThis trial will utilize high quality trial methodologies in accordance with CONSORT guidelines.

It may provide evidence for the effectiveness of acupuncture as a treatment for fibromyalgia either alone or associated with severe depression.Trial registrationISRCTN trial number ISRCTN60217348 (19 October 2010)
