On Wednesday, the FDA Pediatric Advisory Committee handed the agency a mixed message regarding warnings about selective list of psychotropic drugs prescribed for treating ADHD symptoms.
On Thursday, FDA’s Psychopharmacology Advisory Committee voted 12 to 1 to reject approval of the drug modafinil as a treatment for ADHD in children. FDA safety officers had similarly recommended rejection because of a link to Stevens-Johnson Syndrome, a potentially fatal skin disease that usually results from a drug reaction. However, FDA administrators had pushed for its approval. The following seemingly contradictory news reports reflect the pediatric committee’s mixed message: The New York Times: "Stimulants like Ritalin lead a small number of children to suffer hallucinations that usually feature insects, snakes or worms, according to federal drug officials, and a panel of experts said on Wednesday that physicians and parents needed to be warned of the risk. The panel members said they hoped the warning would prevent physicians from prescribing a second drug to treat the hallucinations caused by the stimulants, which one expert estimated affect 2 to 5 of every 100 children taking them.” http://www.nytimes.com/2006/03/23/health/23fda.html?ei=5094&en=e18b3ebe56dce 6bf&hp=&ex=1143090000&partner=homepage&pagewanted=print The Associated Press: "A federal advisory panel on Wednesday rejected recommending that popular drugs used to treat attention deficit hyperactivity disorder should bear the strongest type of warning of the potential cardiovascular and psychiatric risks they pose. The consensus move by the Food and Drug Administration's pediatric advisory committee leaves in doubt whether the agency will require the so-called "black-box" labels on the drugs, which include Ritalin. The panel, in simply recommending easier-to-understand language on the labels, broke with another committee that had recommended last month that the drugs include the more dire warnings. The pediatric advisory committee, without voting, did recommend adding more information to the labels for the benefit of doctors, patients and parents."
FDA’s review of adverse effects of psychostimulant drugs and Strattera (which is technically in the antidepressant class), shows that 2-5 children out of every 100 treated with these drugs are at risk of becoming psychotic with hallucinations. Hallucinations are traumatic destabilizing symptoms of severe pathology. No one knows what lasting psychiatric risks such experiences in young children may bode. These psychiatric risks are compounded by cardiovascular risks. In addition, the ADHD drugs are also associated with violence towards self and others, including suicidal behavior, violence, and serious cardiovascular risks.
The discussion focused on selected drugs and selected risks. FDA safety officers presented incontrovertible evidence of the drugs inducing psychosis in children:
"A substantial proportion of psychosis-related cases were reported to occur in children age ten years or less, a population in which hallucinations are not common. The occurrence of such symptoms in young children may be particularly traumatic and undesirable, both to the child and the parents. The predominance in young children of hallucinations, both visual and tactile, involving insects, snakes and worms is striking, and deserves further evaluation. Positive rechallenge (i.e., recurrence of symptoms when drug is re-introduced) is considered a hallmark for causality assessment of adverse events. Cases of psychosis related events which included a positive rechallenge were identified in this review for each of the drugs included in this analysis." See: http://www.fda.gov/ohrms/dockets/ac/06/briefing/2006-4210B-Index.htm
The federal standards that guide the FDA actions are as follows:
FDA’s standard for warning labels: “The labeling shall be revised to include a warning as soon as there is reasonable evidence of an association of a serious hazard with a drug; a causal relationship need not have been proved.” 21 C.F.R. § 201.57(e)
FDA’s standard for Black Box warning: “Special problems, particularly those that may lead to death or serious injury, may be required by the Food and Drug Administration to be placed in a prominently displayed box. The boxed warning ordinarily shall be based on clinical data, but serious animal toxicity may also be the basis of a boxed warning in the absence of clinical data.” 21 C.F.R. § 201.57(e) In 2004, when an FDa analysis revealed that antidepressants caused rather than prevented suicidal behaviors, the APA proclaimed that putting Black Box warnings on the drugs would induce a public health crisis:
“We restate our continued deep concern that a “black box” warning on may have a chilling effect on appropriate prescribing for patients. This would put seriously ill patients at grave risk.” (APA News Release, 2004)
AHRP challenges the APA to show evidence that any child suffered harm when parents made an informed decision against exposing their child to antidepressants—based on the information contained in these drugs’ Black Box label warnings
On Wednesday, the APA and the other stakeholders repeated the familiar chicken little refrain: “We urge the FDA to avoid the use of black box warnings…[it] is we believe, premature and may lead to needless public alarm that will discourage those who benefit from these medications from taking them.”
In 2004, two combined FDA advisory committees rejected the self-serving arguments of the APA and the other drug promoters whose claims rested on an appeal to their own presumed “authority.” By contrast, Wednesday’s committee hearing gave one the sense of a "show trial"—as if the outcome had been pre-determined in support of an agenda. That agenda was to facilitate industry’s marketing goals no matter what the validated evidence shows.
“We know that appropriate intervention for ADHD actually saves lives. Specifically, treatment reduces the risk of serious accidents, including accidents which lead to head injury and permanent disability.” (David Fassler, MD, APA Trustee-at large)
Dr. Fassler cannot provide evidence to support that claim. To do so would require scientific studies showing that (1) ADHD increases the risk of death, and (2) ADHD drugs prevent the risk of death. There is no such evidence.
Instead, the evidence contradicts his claims. The Pediatric Advisory Committee shut its eyes and ears to documented scientific evidence contradicting such unsupported claims. A 2005 Meta-Analysis of ALL (2,287) ADHD studies worldwide found: no evidence demonstrating clinical efficacy; no evidence that drugs improve academic performance, risky behaviors, social achievements or other measures; and no evidence on long-term safety of the drugs. See: http://www.ohsu.edu/drugeffectiveness/reports/documents/ADHD%20Final%20Repor t.pdf See also, Are ADHD drugs safe? Report finds little proof, News Tribune: http://www.ahrp.org/infomail/05/09/13a.php
Underscoring the Committee’s blind acceptance of arguments that appeal to “authority” (i.e., “we know…” ), the committee chairman, Dr. Robert Nelson, ignored the Oregon Meta analysis, ignored the FDA review, and echoed instead, APA’s unsubstantiated claims: "You have overwhelming evidence of efficacy with two rare adverse events … A black box would scare many patients away from treatment." (Reuters News/ ABCNews:http://abcnews.go.com/Health/wireStory?id=1757521 )
No one can argue—indeed, even FDA officials agree that documented evidence shows that some children prescribed ADHD drugs have been harmed. If parents are warned about the nature of the potential drug-induced harms, some may decide to forgo drugs and try alternative interventions. What possible good can come from keeping parents uninformed about evidence of a 2% to 5% risk of psychosis for children taking psychostimulant drugs?
The committee’s reluctance to recommend strong warnings about life-threatening risks presumes, without evidence, that reduced prescribing of psychotropic drugs will “put seriously ill patients at grave risk.” But the evidence shows that clinical benefits are uncertain, while serious risks to children are inevitable.
The Pediatric Advisory Committee served industry’s interests while ignoring the nature and magnitude of the alarming risks for children. The same agenda is also reflected in FDA's acceptance of "evidence" of a drug’s safety from clinical trials not designed to detect a psychoactive drug’s adverse effects, from trials not lasting long enough to detect hazards that do not emerge immediately.
One probing question (by panel member, Dr. Thomas Newman, at the end of a sponsor's presentation in which the magnitude of risk was trivialized) addressed the time frame in which adverse effects were reported: Company representatives acknowledged that the safety data reported to the FDA had been obtained from a clinical trial in which 300 children were exposed to the drug for only TWO WEEKS. The drug is being prescribed daily for long-term use...This invalid standard of drug safety makes a mockery of the drug approval process, raising doubt about the credibility of an FDA seal of approval. See: AHRP recommendations for action needed to protect children from widespread prescribing of psychoactive drugs for ill-defined behavioral symptoms. Action is also needed to protect the safety of their school mates who are also at risk of drug-induced violence. http://www.ahrp.org/cms/content/view/113/28/ * The FDA has not even analyzed the high incidence of severe drug-induced adverse effects associated with antipsychotics. Though these drugs have not been approved for use in children, the prescribing rate for children aged 2-18 increased fivefold between 1995-2002. More than 2.5 million children were prescribed antipsychotics in 2002--50% of the time for ADHD.

GAITHERSBURG, Md., March 22 — Stimulants like Ritalin lead a small number of children to suffer hallucinations that usually feature insects, snakes or worms, according to federal drug officials, and a panel of experts said on Wednesday that physicians and parents needed to be warned of the risk.
The panel members said they hoped the warning would prevent physicians from prescribing a second drug to treat the hallucinations caused by the stimulants, which one expert estimated affect 2 to 5 of every 100 children taking them. Instead, they said, the right thing to do in such cases was to stop prescribing the stimulants.
On Feb. 9, a different advisory committee voted 8 to 7 to recommend that the Food and Drug Administration place its most serious warning label, a so-called black box, on the labels of stimulants to warn that they could have dangerous effects on the heart, particularly in adults. That recommendation grew out of reports that 25 people, mostly children, had died suddenly while taking the drugs.
The twin conclusions come more than 50 years after Ritalin was first approved to treat attention deficit disorder and hyperactivity. Since then, stimulants have become among the most widely prescribed medicines in the world. In the United States alone, about 2.5 million children and 1.5 million adults take them; as many as 10 percent of boys ages 10 to 12 do. In addition to Ritalin, two other stimulants, Adderall and Concerta, are popular.
The drugs have been studied in hundreds of trials over five decades and have proven to be extremely effective. But they have always been controversial, with some experts saying they are overprescribed. It is a measure of the difficulty of uncovering the physiological effects of medicines that experts are only now grappling with some of the drugs' serious, though rare, physical and mental effects.
Dr. Thomas B. Newman, an epidemiologist at the University of California, San Francisco, who is a member of the pediatric advisory committee, estimated that out of 100 patients treated for a year with stimulants, 2 to 5 will suffer serious psychotic episodes like hallucinations. "It's a small number, but it's real," said Dr. Robert M. Nelson, an intensive-care physician at Children's Hospital of Philadelphia and chairman of the committee.
Dr. Kate Gelperin, an F.D.A. drug-safety specialist, told the committee that the agency had discovered a surprising number of cases in which young children given stimulants suffered hallucinations. Most said that they saw or felt insects, snakes or worms, Dr. Gelperin said.
Dr. Gelperin described the case of a 12-year-old girl who said that insects were crawling under her skin. Another child was found by his parents crawling on the ground and complaining that he was surrounded by cockroaches. In both cases, the hallucinations disappeared after drug therapy was stopped. The boy's doctor persuaded his parents to give him stimulants again, and his hallucinations reappeared.
F.D.A. officials made clear to the advisory panel that they considered the reports of hallucinations a problem that deserved a label warning. "We were struck by the hallucinations," said Dr. Rosemary Johann-Liang, deputy director of the division of drug-risk evaluation at the F.D.A. "We felt it was a drug effect."
The agency does not have to follow the conclusions of its advisory panels, but it usually does. Dr. Robert Temple, director of the Office of Medical Policy at the agency, said after the meeting that the agency would "turn quite quickly to implementing the recommendations we've gotten." Dr. Temple added, "The area of uncertainty is what to do about the black-box warning on cardiovascular risks in adults."
After the advisory committee meeting in February, agency officials said they had no intention in the near future of placing such warnings on stimulant labels about their potential heart risks.
Wednesday's panel, made up mostly of experts in pediatric medicine and psychiatry, discussed only the potential risks of the drugs among children, while February's group focused mostly on the risks to adults. The pediatric panel agreed with the earlier group that children who have heart problems should probably not be given stimulants. But most children who die suddenly from heart ailments never knew they were at risk, and most children put on stimulant therapy are not given thorough heart evaluations. "You can't screen 2.5 million children" with intensive heart evaluation tests, Dr. Nelson said. Copyright 2006The New York Times Company

A federal advisory panel on Wednesday rejected recommending that popular drugs used to treat attention deficit hyperactivity disorder should bear the strongest type of warning of the potential cardiovascular and psychiatric risks they pose.
The consensus move by the Food and Drug Administration's pediatric advisory committee leaves in doubt whether the agency will require the so-called "black-box" labels on the drugs, which include Ritalin. The panel, in simply recommending easier-to-understand language on the labels, broke with another committee that had recommended last month that the drugs include the more dire warnings.
The pediatric advisory committee, without voting, did recommend adding more information to the labels for the benefit of doctors, patients and parents. "I wouldn't use the word 'tougher,' said panel chair Dr. Robert Nelson. "'Clearer.'" The agency isn't required to follow the advice of its advisory committees, but usually does.
Nearly 3.3 million Americans age 19 and younger used an ADHD drug last year, according to Medco Health Solutions Inc., a prescription drug benefit program manager. Psychiatrists and others had urged the committee to move cautiously before recommending strengthened warnings of heart attacks, hallucinations and other potential risks associated with the drugs.
In February, the FDA's Drug Safety and Risk Management advisory committee voted to recommend the agency add the strongest possible warning to some of the drugs, in that case to alert doctors, patients and parents of the uncertainty regarding the risk they may pose to the cardiovascular system. The FDA then asked the pediatric panel to examine that same issue, as well as reports that psychosis or mania can occur in some juvenile patients at normal doses of any ADHD drug.
Adding black-box warnings to some or all the drugs, which also include Adderall and Strattera, could cause more harm than good, some experts told the panel prior to the vote. "I suggest confusion, polarizing viewpoints, initial press hysteria. But then what?" asked Julie Zito, a University of Maryland associate professor in pharmacy and psychiatry.
The FDA has struggled since last year with the question of how to communicate the potential risks associated with ADHD drugs. Psychiatrists and mental health advocates said leaving the disease untreated could rival the risks the drugs may pose. "It is important to not let the discussion of ADHD medications overshadow the public health crisis of untreated mental health disorders in children," said Cynthia Wainscott of the National Mental Health Association. Her 16-year-old granddaughter has ADHD.
Ritalin is manufactured by Novartis Pharmaceuticals Corp. and in generic form by other companies; Adderall is made by Shire Pharmaceuticals Inc.; and Strattera, which is produced by Eli Lilly and Co.
FDA officials say patients and doctors should be aware that the small number of reported psychiatric events could represent side effects of the drugs, although they cannot point to a definitive link. However, they noted a "complete absence" of similar reports in children treated with dummy pills during dozens of clinical trials of the drugs. In many children, the events ceased once they stopped taking the drugs — and resumed in some once they restarted. "That's unlikely to be due to random chance, suggesting some effect of the drugs," said Dr. Andrew Mosholder, of the FDA's division of drug risk evaluation.
McNeil Consumer & Specialty Pharmaceuticals said in briefing documents that it is customary to weigh the "therapeutic benefits and potential risks" of treatment. The unit of Johnson & Johnson makes Concerta, a long-acting form of methylphenidate, the drug in Ritalin. Novartis believes current Ritalin labels are adequate, company medical safety director Dr. Todd Gruber said.
Jacqueline Bessner of Ishpeming, Mich., said her daughter, Leanne, 15, hanged herself last year two months after starting treatment with Concerta. Bessner said more black-box warnings would be useless without increased counseling and monitoring of patients. "It's being handed out like it's candy," Bessner said of ADHD drugs. "It's too easily accessible."
A different FDA panel planned to consider on Thursday an application by Cephalon Inc. to sell its sleep-disorder drug Provigil, or modafinil, as an ADHD treatment for children. The FDA wants members of its psychopharmalogic drugs advisory committee to examine that request, including whether serious skin rashes seen in children treated with modafinil should merit special warnings, follow-up studies and steps to limit the risk.

http://abcnews.go.com/Health/wireStory?id=1757521 ABC News Mar 22, 2006 — GAITHERSBURG, Maryland (Reuters) - U.S. advisers on Wednesday called for new information about health risks on the labels of attention deficit drugs, but stopped short of recommending the strongest possible warning saying they did not want to frighten patients. The panel of pediatric experts reviewed reports of heart problems and psychotic behavior such as hallucinations in children who took the medicines, which include Novartis AG's Ritalin and Shire Plc's Adderall.
Patients and parents should know about the reports even though it is unclear if the drugs contributed to the problems, panel members said. They stopped short of recommending the strong "black box" warning that a different advisory panel supported last month.
"You have overwhelming evidence of efficacy with two rare adverse events … A black box would scare many patients away from treatment," panel chairman Dr. Robert Nelson, the panel's chairman.
