Early-Stage Multiple Sclerosis Reversed By Stem Cell Transplant

Researchers from Northwestern University's Feinberg School of Medicine appear to have reversed the neurological dysfunction of early-stage multiple sclerosis patients by transplanting their own immune stem cells into their bodies and thereby "resetting" their immune systems.

"This is the first time we have turned the tide on this disease," said principal investigator Richard Burt, M.D. chief of immunotherapy for autoimmune diseases at the Feinberg School.

In the procedure, Burt and colleagues treated patients with chemotherapy to destroy their immune system. They then injected the patients with their own immune stem cells, obtained from the patients' blood before the chemotherapy, to create a new immune system. The procedure is called autologous non-myeloablative haematopoietic stem-cell transplantion.

"We focus on destroying only the immune component of the bone marrow and then regenerate the immune component, which makes the procedure much safer and less toxic than traditional chemotherapy for cancer," Burt said. After the transplantation, the patient's new lymphocytes or immune cells are self-tolerant and do not attack the immune system.

In previous studies, Burt had transplanted immune stem cells into late-stage MS patients. "It didn't help in the late stages, but when we treat them in the early stage, they get better and continue to get better," he said.

"What we did is promising and exciting, but we need to prove it in a randomized trial," Burt noted. He has launched a randomized national trial.

BREAKING MEDICAL NEWS: Bone Marrow Transplant Shows Promise for MS

CHICAGO, Jan. 29 -- Patients with relapsing-remitting multiple sclerosis had significant improvement in neurologic disability after nonmyeloablative hematopoietic stem cell transplantation, investigators here reported.

After three years of follow-up, 17 of 21 patients maintained at least a one-point improvement in a standard disability scale, Richard K. Burt, M.D., of Northwestern University, and colleagues reported online in The Lancet Neurology.

All patients were progression free at last follow-up, and 16 were relapse free.

"Autologous nonmyeloabalative hematopoietic stem cell transplantation for patients with relapsing-remitting MS with active inflammatory disease and frequent exacerbations is a feasible procedure that not only seems to prevent neurological progression, but also appears to reverse neurological disability," the authors concluded.

However, they noted that "these results need to be confirmed in a randomized trial."

Hematopoietic stem cell transplantation has been evaluated throughout the world as therapy for MS. However, the trials typically involved patients with late secondary-progressive disease, and most had no improvement in neurologic disability, the authors said.

"Neurological deficits during the late secondary-progressive phase of MS are mostly caused by neurodegeneration from axonal atrophy, for which no immune-based therapy, including hematopoietic stem cell therapy, has been effective for reversing the deficits," they noted.

In contrast, they continued, demyelination associated with relapsing-remitting MS is mediated by immune cells. Therapy emphasizes immune modulation to ameliorate inflammatory processes that damage the central nervous system.

Standard therapies aim to delay disease progression. Dr. Burt and colleagues sought to reverse neurologic disability with hematopoietic stem cell transplantation in patients who had not reached the largely irreversible neurodegenerative phase of the disease process.

Their study involved patients whose disease had not responded to immune modulation but was still in an active inflammatory state. The patients' median age was 33, mean baseline expanded disability scale score (EDSS) was 3.1, and median disease duration before transplantation was five years.

The patients received a median infused dose of hematopoietic stem cells of 11·40x106 CD34+ cells per kg, mobilized with 2 g/m2 of cyclophosphamide and 10µg/kg/d filgrastim (Neupogen).

The conditioning regimen for the cells consisted of 200 mg/kg cyclophosphamide and either 20 mg alemtuzumab (Campath) or 6 mg/kg rabbit antithymocyte globulin.

The primary outcomes were progression-free survival and reversal of neurologic disability three years after transplantation.

Engraftment of white cells occurred a median of nine days after transplantation, and hospital length of stay averaged 11 days.

One patient developed diarrhea caused by Clostridium difficile, and two patients had dermatomal zoster. Two of 17 patients treated with alemtuzumab developed late immune thrombocytopenic purpura that resolved with standard therapy.

Five patients relapsed but achieved remission again after immunosuppressive therapy.

After a mean follow-up of 37 months, 81% of patients had improved by at least one point on the EDSS.

As determined by EDSS scores, the patients had significant improvement in neurologic disability (P<0.0001).>

Significant improvement also occurred in the neurologic rating scale (P=0.0001), paced auditory serial addition test (P=0.014), 25-foot walk (P<0.0001),>P<0.0001).>

In an accompanying commentary, Gianluigi Mancardi, M.D., of the University of Genova in Italy, noted that the conditioning regimen plays a major role in the success of hematopoietic stem cell transplantation.

He noted that the regimen used by Dr. Burt and colleagues caused "modest, if not negligible" toxicity.

The fact that five patients relapsed, suggested that "nonmyeloablative conditioning regimens might not be sufficient to eradicate inflammatory activity in the long term."

Despite the relapses, Dr. Mancardi continued, "the results imply that this [conditioning regimen] is a valuable alternative to the transplant conditioning therapies used so far."

Merck’s Multiple Sclerosis Pill Prevents Relapses

(Bloomberg) -- Merck KGaA, the German drugmaker seeking to be first with an oral medicine for multiple sclerosis, said its experimental pill cladribine prevented flare-ups of the debilitating neurological disease in a study.

Patients who took the pill suffered 55 to 58 percent fewer relapses, depending on the dose, than those who took a placebo during the two-year study, the Darmstadt, Germany-based company said today.

The German drugmaker said it is on track to submit an application for approval to European and U.S. regulators by the middle of this year. Merck shares climbed 5.53 euros, or 8.6 percent, to 69.89 euros in Frankfurt.

Cladribine tablets are among several oral medications for multiple sclerosis now in the final stage of clinical testing.

Used to treat leukemia since the 1990s, the drug reduces the number of lymphocytes, white blood cells believed to be linked to multiple sclerosis, a disease in which the body’s immune system attacks the central nervous system. Side effects of headaches and cold symptoms were comparable in the dummy pill and cladribine patient groups, Merck said today.

Merck and Swiss drugmaker Novartis AG have said they will ask regulators in the U.S. and Europe this year to approve pills to treat the disease. Novartis released preliminary results last month showing its pill, known as fingolimod, cut relapse rates as much as 52 percent more than a standard therapy.

Side Effects
Merck already makes Rebif, one of the three beta interferons now commonly prescribed for multiple sclerosis. The injected drug, which will begin to lose patent protection in 2012, had 1.22 billion euros ($1.68 billion) in sales in 2007.

Patient advocates will be watching the long-term side effects of cladribine, which was given over a shorter time period to leukemia patients than it likely will be to multiple sclerosis sufferers, said Dr. Doug Brown, research manager for the Multiple Sclerosis Society in London, before today’s results were released. Brown said they will also want to see whether the oral medicines slow progression of the disease.

Merck and Novartis have said they will present full clinical trial results for their experimental pills at medical conferences later this year. Merck said the new study, which it funded, followed about 1,300 patients.

FDA allows first test of human stem cell therapy

WASHINGTON (Reuters) - The U.S. Food and Drug Administration has cleared the way for the world's first study of human embryonic stem cell therapy, Geron Corp said on Friday.

The California biotechnology company plans to start a clinical trial to try to use the stem cells to regrow nerve tissue in patients with acute spinal cord injury.

"This marks the beginning of what is potentially a new chapter in medical therapeutics -- one that reaches beyond pills to a new level of healing: the restoration of organ and tissue function achieved by the injection of healthy replacement cells," Geron Chief Executive Thomas Okarma said in a statement.

Shares of Geron rose nearly 30 percent to $6.75 in premarket electronic trading on Nasdaq.

The FDA rejected his company's first request to conduct the trial of GRNOPC1, Oligodendroglial Progenitor Cells. It put the trial on hold in May."

If GRNOPC1 eventually does become the first human Embryonic Stem Cell drug to receive an approved Biologic License Application it could be as important to drug therapy as the discovery of Salvarsan or penicillin," drug analysts Stephen Brozak and Daniel Mallin of WBB Securities LLC said in a statement.

Salvarssan was the first modern drug, used to treat syphilis early in the last century.

Joel Sendek of Lazard Capital Markets was cautious, saying he was recommending a hold in Geron shares. "Cellular-based therapies carry substantially more regulatory risk than do traditional small-molecule drugs or protein therapeutics," he said.

AT ODDS
Former President George W. Bush had been at odds with Congress, researchers and advocates for years over the issue and by executive order restricted federal funding of work involving human embryonic stem cells.

President Barack Obama, who succeeded Bush on Tuesday, had been widely expected to rescind that directive. Although the FDA says it does not make decisions based on politics, the company made the decision public just days after Obama was sworn into office.

Stem cells are the body's master cells, giving rise to all the tissues, organs and blood. Embryonic stem cells are considered the most powerful kinds of stem cells, as they have the potential to give rise to any type of tissue.

But they are difficult to make, requiring the use of an embryo or cloning technology. Geron and some other companies have been pursuing the goal without the use of federal funds.

Advocates say stem cell-related research could lead to a whole new field of regenerative medicine, in which patients could get transplants and treatments for Parkinson's, juvenile diabetes, cancer, injuries and a range of other ills.

"If safe and effective, the therapy would provide a viable treatment option for thousands of patients who suffer severe spinal cord injuries each year," Richard Fessler, professor of neurological surgery at the Feinberg School of Medicine at Northwestern University said in a statement.

Experimental autoimmune encephalomyelitis (EAE) is often termed "the" model of human multiple sclerosis (MS). This is, however, an oversimplification. MS is a multifaceted disorder, with no single experimental model representing the entire complexity of the human disease.

FDA Says Avoid All Products Containing Peanut Butter

ROCKVILLE, Md., Jan. 19 -- Consumers should not eat products containing peanut butter until they can be cleared of a connection to the ongoing nationwide salmonella outbreak, the FDA warned.

The recommendation does not apply to name-brand jars of peanut butter available in grocery stores, which have not been implicated in the rash of infections.

The following recalls have been announced:
Kellogg Company recalled certain Austin and Keebler brand peanut butter sandwich crackers and some snack-size packages of Famous Amos and Keebler peanut butter cookies.

Hy-Vee Inc. recalled its Peanut Butter Cookies, Monster Cookies, Peanut Butter Reese's Pieces Cookies, Peanut Butter Chocolate Chip Cookies, Lunchbox Reese's Pieces Cookies, Lunchbox Peanut Butter Cookies, People Chow Party Mix, and Assorted Truffle Fudge.

Perry's Ice Cream recalled select ice cream products sold under the brand names Perry's, Shurfine, and Wegmans that contain peanut butter sauce.

McKee Foods Corporation recalled all sizes of Little Debbie Peanut Butter Toasty sandwich crackers and Little Debbie Peanut Butter Cheese sandwich crackers.

The South Bend Chocolate Company recalled several varieties of chocolate containing peanut butter.

Ralcorp Frozen Bakery Products recalled several varieties of peanut butter cookies, including some of those sold under the Wal-Mart Bakery and Food Lion Bake Shop brands.

The FDA will keep track of these and other related recalls at the following Web site: Salmonella Typhimurium Outbreak.

"In terms of food products that contain peanut butter but have not yet been recalled," Dr. Sundlof said, "we urge consumers to postpone eating these products until further information becomes available about whether that product may be affected."

The more severe illnesses have involved older and very young individuals, as well as those with weakened immune systems. - Full Story in Medpage Today

Management strategies for improving the tolerability of interferons in the treatment of MS.

Interferon beta therapies for multiple sclerosis (MS) are well tolerated during long-term use, but the first year of treatment is a critical risk period for nonadherence and discontinuation. Some of the most common reasons for discontinuation include adverse effects (including flu-like symptoms and injection site reactions). Minimizing the impact of adverse effects is crucial in helping patients adhere to their treatment regimens, and improving their chances of better health over the longer term.

Do Patients Trust Doctors Too Much?

When a doctor friend of mine recently heard a radio ad for a Web site where patients could rate their doctors, he almost drove off the road.

“I can’t believe they’ve added doctors to the list,” he said of the site, Angie’s List, perhaps best known for its user-generated report cards on local contractors.

“Why do patients want to assess my relationship with them in the same way they evaluate a roofing job?” he asked, shaking his head over what he interpreted to be more evidence of the disintegrating doctor-patient relationship.


I agreed with my friend and, not long after our conversation, curiosity piqued, I paid for a subscription to the site.

The pages seemed to overflow with information. There were reviews of roofers, childcare providers, dog walkers and tattoo and piercing shops. One of the newest and most popular categories was doctors, where reviewers could grade their doctors by answering the site’s specific questions and elaborate with additional comments.

Doctors, like every other business, service, and facility listed, were evaluated using the same generic report card. Everyone received a grade for each of five categories — price, quality, responsiveness, punctuality, and professionalism — as well as an answer to the all-important bottom line question: Hire again?

So much for Marcus Welby, I thought, after going through a couple of the reviews.

But the more I read, the more I realized that there was a correlation between good grades and attentiveness. Reviewers gave less-than-passing, and even failing, grades to those physicians who seemed rushed, brusque or distracted; and they uniformly gave “A’s” and “B’s” to doctors who were warm, concerned and focused.

Even more could be gleaned from what went unsaid. Amongst the many comments I read, I found almost no mention of a doctor’s actual medical skill.

That was not the case with roofers, for example, where in addition to grades, reviewers’ comments offered great specifics — and even photographs — regarding the quality of the handiwork, the types of supplies used and the aesthetics of the finished product. All the detailed commentaries fleshed out each company’s final grades, and it was easy to get a pretty good sense of an individual roofer’s skill and craftsmanship.

With doctors, however, there were no detailed descriptions of medical skill beyond the overall grade. Instead, the playing field seemed oddly level.

One surgeon, it appeared, could operate much like another; pediatricians and internists could diagnose and manage with similar abilities; and obstetricians could deliver babies regardless of shape, size, or form.

All doctors, whatever their grades, seemed to possess similar and interchangeable skills that they could then apply to you. You just might not like the way they treated you in the process.


I found this extraordinary degree of trust astonishing. When I look for a doctor, of course I am concerned about how that doctor relates to me as a patient. But there are a whole host of other issues I consider as well, such as the physician’s training, board certification, experience, membership in a respected professional society, safety records and hospital affiliations. And I admit that I don’t feel comfortable as a patient in another doctor’s hands until I learn the answers to at least some of my questions.

But as it turns out, most patients don’t feel the same way. And many of them are just as trusting when it comes to treatment specifics.

Earlier this year, the American College of Surgeons, the national scientific and educational organization of surgeons, conducted a nationwide survey that found that the average patient devotes an hour or less to researching his or her surgery or surgeon. While prospective patients worry about the costs or complications of an operation, they don’t necessarily look for information that would address their concerns.

In fact, more than a third of patients who had an operation in the last five years never reviewed the credentials of the surgeon who operated.

Patients are more likely to spend time researching a job change (on average, about 10 hours) or a new car (8 hours) than the operation they are about to submit to or the surgeon who wields the knife.


And many patients are satisfied with the answers they receive from their surgeon or primary care doctor, whoever those individuals happen to be.


I was intrigued by the survey, so I called Dr. Thomas Russell, executive director of the American College of Surgeons. “There is a tendency, probably more so now than in the era of Marcus Welby, for patients not to get particularly involved and not to feel compelled to look into their surgery or surgeons,” he told me.

There are consequences to that kind of blind trust. “Today, medicine and surgery are really team sports,” Dr. Russell continued, “and the patient, as the ultimate decision maker, is the most important member of the team. Mistakes can happen, and patients have to be educated and must understand what is going on.”

Dr. Russell has made it part of his personal mission to educate patients and recently wrote a book, “I Need an Operation...Now What? A Patient’s Guide to a Safe and Successful Outcome,” as a response to the survey. ”Patients and their families need to be armed with the fortitude and the right questions in order to find the best doctors for their problems,” he said.

In other words, a healthy doctor-patient relationship does not simply entail good bedside manners and responsible office management on the part of the doctor. It also requires that patients come to the relationship educated about their doctors, their illnesses and their treatment.

BREAKING NEWS: "Early Biogen Drug Seeks To Repair MS Damage"

IN THE PIPELINE: Early Biogen Drug Seeks To Repair MS Damage

NEW YORK -(Dow Jones)- Reversing the damage done by multiple sclerosis would be a dream come true for patients of the debilitating disease, and there is some promising research working toward that goal.

The condition is thought to occur when the body literally attacks itself and current therapies only seek to slow or stop that situation. But Biogen Idec Inc. (BIIB) is developing a drug that may repair the damage to the nervous system from the disease, a prospect that could also aid victims of other neurological conditions.

"This is the first entry into our clinical pipeline, or really in anyone else's pipeline that we are aware of, for a truly restorative therapy for MS," said Ken Rhodes, vice president of discovery neurobiology at Biogen.

Though the Cambridge, Mass., biotech company is hopeful for the drug's development, it is yet to be tested in humans and, assuming success, it wouldn't be available to patients for many years.

Much remains unknown about multiple sclerosis, but it is thought to be an autoimmune disease that occurs when the body attacks myelin, the protective insulation surrounding the nerve fibers called axons in the central nervous system. The myelin damage can distort or block messages carried by the axons and result in a wide variety of symptoms such as vision problems, limb numbness and paralysis.

Though the cause is a mystery, MS is thought to develop from some degree of genetic predisposition working in combination with environmental triggers earlier in the life. It is more common in women and tends to develop between the ages of 20 and 50, according to the National Multiple Sclerosis Society.

Current treatments for the disease all involve trying to alter the immune system's ability to attack the nervous systems, notes John Richert, executive vice president of research and clinical programs for the MS Society.

A popular group of drugs are the beta-interferons, which reduce disease flare ups and are similar to proteins that play a role in the immune system. Those are Biogen's Avonex, Bayer AG's (BAY.XE) Betaseron, and Rebif, marketed by Pfizer Inc. (PFE) and Germany's Merck KGaA (MRK.XE).

Teva Pharmaceuticals Industries Inc. (TEVA) makes Copaxone, which seems to fight the nerve-attacking immune cells by acting as a myelin decoy. Biogen and partner Elan Plc (ELN) also sell Tysabri, which prevents those immune cells leaving the blood stream so that they can't get to the brain or spinal cord.


Early Success


The focus of much of Biogen's current discovery research in MS is focused on restorative therapy, but its most advanced program is led by biologist Sha Mi, who joined the company in 2000 and studied why the axons in MS lesions weren't generating new myelin.

Research found that cells called oligodendrocytes were being prevented from undergoing the needed differentiation for them to build new myelin.

Furthermore, Mi found that the so-called LINGO molecule was inhibiting that differentiation and that using an antibody to block LINGO's function could allow myelin to regenerate.

"When we block LINGO function, we can see robust oligodendrocyte differentiation, and they interact with the axon for remylination," said Mi.

The antibody has been shown to be effective in mouse models that are accepted as being useful for mimicking the properties of MS.

The antibody helped the mice grow new myelin, and it also helped with the integrity of the nerve fibers, in comparison to untreated mice, thus aiding nerve function. More myelin growth occurred closer to the site of the antibody application, also suggesting its responsibility for the effects.

The research showed that the antibody didn't prevent the loss of myelin in an animal model, but it did reduce the effects of disease progression.

Though the development is clearly exciting, the antibody is only in toxicity studies that are expected to be completed later this year.

Biogen expects to file an Investigational New Drug application with Food and Drug Administration in the fourth quarter and begin human studies starting shortly thereafter.


Rhodes noted that the next goal is to conduct proof-of-concept studies to determine if the drug inhibits LINGO function in humans with the same positive effects.


Hopeful Future


The possibility of repairing damage done by MS and reducing symptoms of the disease would be revolutionary for MS patients, but Dr. Richert believes that currently used therapies are likely to continue as the best treatment for new patients who may not have a lot of nerve damage.

Regeneration would be used on patients who already have neurological deficits, he said, as well as those whose disease continues to progress regardless of treatment.

In order to provide the best benefit, Dr. Rhodes said that the anti-LINGO antibody would likely be used in combination with one of the more traditional immunosupressive approaches.

"As you dampen the immune response, you treat with anti-LINGO to try and actually facilitate recovery and repair," he said.

If successful, the antibody could have a future in treating other neurological disease such as Parkinson's, or even help repair damage done to the spinal cord.

Biogen has a number of programs to explore the antibody's use in other diseases but is cautious on any of those prospects.

"The preclinical data supporting the utility of those indications isn't as well developed yet as it is with MS," Dr. Rhodes said.

Last year, research was published on another Biogen pipeline product, a protein called neublastin, that promoted the regeneration of damaged sensory nerve cells in order to restore sensory and motor function. The drug is being studied to treat peripheral nervous system diseases.

New Interferon Formulations Promise To Eliminate Injections In MS Treatment

Nerveda Inc. and Aegis Therapeutics LLC today announced preclinical results from their joint collaboration aimed at developing non-injectable formulations of the beta-interferons. The beta interferons, beta-1a (tradename Rebif(R)), and beta 1b (tradenames Betaseron(R) and Betaferon(R)) are closely related injectable protein drugs in the interferon family that are used to treat both the relapsing-remitting and secondary-progressive forms of multiple sclerosis (MS). The beta interferons are currently administered by subcutaneous injection and have been proven clinically to slow the advance of multiple sclerosis and reduce the frequency of attacks. Current worldwide combined annual sales of Rebif(R), Betaseron(R) and Betaferon(R) are approximately $4 Billion.

Because proteins are large and fragile molecules, they cannot be administered orally and are typically administered by injection. They are often subject to instability due to aggregation of the protein molecules -- particularly upon storage and handling at non-refrigerated temperatures. The resulting protein aggregates are more poorly absorbed into the blood stream upon injection due to their increased size, and induce development of circulating antibodies to interferon in patients that reduce the effectiveness of the drug over time.

Leading medical scientists at Johns Hopkins University, expert in the treatment of neurological diseases, in collaboration with Nerveda and Aegis have applied Aegis' Intravail(R) transmucosal absorption enhancement, and ProTek(R) protein stabilization technologies to address these problems and have demonstrated for the first time that the beta interferons can be administered intranasally to prevent nerve damage in preclinical animal models of multiple sclerosis. In addition, the new formulations were shown to reduce or eliminate the immunogenicity of Betaseron(R) and Rebif(R), administered either by injection or intranasally, while substantially increasing stability in a stress test involving constant agitation at elevated temperatures for extended periods of time.

Dr. Edward Maggio, Ph.D., CEO of Aegis Therapeutics, who participated in the research, said, "since interferons will continue to be the foundation of MS therapy, it is critical that non-invasive delivery options for patients be developed." Maggio also indicated, "the reduction in immunogenicity and the increase in stability also address a significant unmet need of the currently available beta-interferon therapies."

Nerveda plans to begin testing the new formulation in clinical trials in early 2009 in collaboration with clinicians and scientists at John Hopkins University Medical Center and other sites.

Biogen Says No New Brain Infections In First Tysabri Update

By Thomas Gryta Of DOW JONES NEWSWIRES NEW YORK -(Dow Jones)- Biogen Idec Inc. (BIIB) reported that there were no new cases of a rare brain infection in users of its multiple sclerosis drug Tysabri in the first of its planned weekly Web-based updates on Friday.

The Cambridge, Mass., biotech, which sells Tysabri with Ireland's Elan Plc (ELN), will post the updates in an effort to more consistently disclose incidences of the often fatal condition.

A suspected link to progressive multifocal leukoencephalopathy, or PML, led to Tysabri being pulled from the market for 18 months beginning in 2005. Since the relaunch, the company has reported that four people had confirmed cases of PML, with one dying.

This past summer marked the two-year anniversary of Tysabri's re-launch, raising Wall Street's anxiety over PML-related news. The timeline is important because two patients with PML in 2005 were using the drug for more than two years.

Biogen will post an update of PML cases on the investor relations section of its Web site every Friday at 4:30 p.m. EST and will continue to do so until July 24, which is the third anniversary of the drug's relaunch.

"I think it is going to provide a lot of clarity and almost realtime information to the market to really make decisions and evaluate the situation," said Citigroup analyst Yaron Werber.

Werber has criticized Biogen's former policy of disclosing new cases through 8-K filings with the Securities and Exchange Commission as making investors nervous and pressuring the company's shares.

Biogen's stock, which closed up 30 cents, or 0.6%, at $48.25, is down 17% for the last 12 months.

Elan closed Friday down 31 cents, or 3.6%, at $8.39 and is down 67% in the last year. Tysabri is Elan's biggest seller, making it more sensitive to related news, plus it was hurt by disappointing data over the summer from an Alzheimer's disease drug in development with Wyeth (WYE).

Werber expects the regular updates to help ease of the "fear of the unexpected" in Biogen shares. He agrees with stopping the disclosures in late July, when a clear picture of the PML risk in Tysabri should be firmly established. "

At some point they would be wise to cut this off," he said. "Because this sort of information is going to be very good for the competition. You can't go on marketing a product in this situation forever."

FDA Approves Tramadol Extended-Release Formulation for Chronic Pain

January 6, 2009 — Labopharm announced that the Food and Drug Administration (FDA) has approved an extended-release once-daily formulation of tramadol (Ryzolt) for the management of moderate to moderately severe chronic pain.

The new formulation of tramadol uses the company's proprietary controlled-release technology (Contramid) for oral administration of existing solid-dosage medications and is the first approval in the United States obtained by Labopharm for 1 of these compounds.

A statement from the company announcing the approval on December 31 notes that the formulation is "composed of a dual-matrix delivery system with both immediate-release and extended-release characteristics." Labopharm and marketing partner in the United States, Purdue Pharma, anticipate launching the product in 100-mg, 200-mg, and 300-mg dosage strengths in the second quarter of 2009, the statement adds.

"In a society where people with pain are increasingly demanding simplified dosing regimens, this once-daily formulation of tramadol should be embraced by physicians and patients alike," Nicholas J. Messina III, MD, from Vista Medical Research, in Mesa, Arizona, principal investigator of the US clinical studies of Ryzolt, said in the company release.

DON’T LET ‘iPATIENT’ DETRACT FROM HANDS-ON MEDICINE, STANFORD AUTHOR/EDUCATOR URGES

DON'T LET 'iPATIENT' DETRACT FROM HANDS-ON MEDICINE, STANFORD AUTHOR/EDUCATOR URGES

STANFORD, Calif. — On his first day as attending physician at Stanford, Abraham Verghese, MD, suggested to the ward team that they leave the "bunker" and head out to their patients' bedsides.

"They probably felt that everything I would need to get up to speed on our patients — the necessary images, the laboratory results — was right there in the team room," Verghese wrote in an essay in the Dec. 25 issue of the New England Journal of Medicine. "From my perspective, the most crucial element wasn't."

Verghese makes it quite clear in his journal article: the "chart-as-surrogate-for-the-patient" approach to medical care is no replacement for the skilled, hands-on physical exam.

The advent of computerized medical records and easy availability of diagnostic tests has led to physicians getting to meet the "iPatient" — the virtual construct of a patient based on all the lab tests and imaging — even before they meet the real live human version waiting nearby in a hospital bed.

Speaking about this virtual entity, he writes, "The iPatient's blood counts and emanations are tracked and trended like a Dow Jones Index…. The real patients keep the beds warm and ensure that the folders bearing their names stay alive on the computer."

Describing his article as a reflective essay and a "manifesto for what we are trying to do here," Verghese writes about the new push at Stanford to emphasize and improve bedside examination skills in students and residents in internal medicine, and calls for a similar national effort at all medical schools.

Long a champion of hands-on medicine, Verghese, a best-selling author, arrived at the Stanford University School of Medicine in December 2007 to serve as professor of medicine and senior associate chair for a new program in the theory and practice of medicine. Board-certified in three specialties — internal medicine, pulmonary diseases and infectious diseases — he is widely published in scientific literature and is also a bestselling author. His next book, the novel Cutting for Stone, is due out this month.

In his article, Verghese describes a dialectic tension between the two approaches to patient care. In the first, the traditional or old-school method, the patient's body tells the story. The doctor works as "bedside-sleuth" using inspection and palpitation along with the help of technology to determine a treatment course. Well-trained in the use of tuning forks, stethoscopes and knee hammers, he or she can detect disease in the appearance, in the gait, in a pulse, well before the relevant test might even be ordered.

"I truly believe that good bedside skills make residents more efficient," Verghese wrote. Doctors who rely on hands-on skills tend to order tests more judiciously, reducing the number of unnecessary and expensive trips to the radiology department, he said.

"In a health care system in which our menu has no prices, we can order filet mignon at every meal," Verghese warned.

The hands-on approach also inspires patient confidence in physicians — a difficult-to-measure commodity that many health-care advocates warn has long been in decline. "There's a reason people seek out alternative medicine in droves," Verghese said in an interview. "Those people put hands on a patient."

The growing trend toward the second method — one that focuses on the "iPatient" — parallels the recent explosion in medical technology, Verghese wrote. While not formally taught, "residents seem to have learned it no matter where in the United States they trained."

It's a simple case of putting the cart before the horse.

Today's doctors spend an "astonishing among of time in front of the monitor" charting in the electronic medical record, moving patients through the system, examining tests results. And medical students learn through example. "In short, bedside skills have plummeted in inverse proportion to the available technology," he wrote.

But Verghese doesn't blame technology for this trend. Instead, he turns his attention toward medical education and educators like himself. "How did we reach this state of affairs?" he wrote. "The fault is ours as teachers of medicine."

Today's routine graduation of medical students without serious testing of physical exam skills is akin to licensing pilots without "ever having been in the air with a seasoned examiner," he wrote. "The public would be scandalized."

Verghese suggested U.S. medical schools "might take a lesson from Canada," where physicians are required to pass bedside examination skills tests. And he emphasized the importance of role-modeling by teachers.

At Stanford, the internal medicine department has instituted regular bedside rounds and faculty-development sessions showcasing good bedside technique as a step in that direction, he wrote.

"What is tragic about tending to the iPatient," Verghese wrote, "is that it can't begin to compare with the joy, excitement, intellectual pleasure, pride, disappointment, and lessons in humility that trainees might experience by learning from the real patient's body examined at the bedside."
