Maryland: U.S. Advisers Urge FDA To Address Antipsychotic Drugs Side-Effects In Children: UPDATED

23 Sep

NEWS UPDATE:

DOCTORS and academics risk “professional suicide” if they reveal the adverse side-effects of anti-depressants and other psychiatric medicines, a leading academic psychiatrist has claimed.

Irish-born professor of psychiatry at Cardiff University in Wales, Prof David Healy, also hit out at any of his colleagues who, he said, put the benefits of major pharmaceutical companies ahead of patients.

“Invitations to apply for better jobs, to attend conferences, or simply to go with colleagues to local eateries funded by drug companies are ever less likely to happen for doctors linked to adverse events,” argued the professor, who has repeatedly raised concerns over the issue in Britain.

“Offers to describe problems at professional meetings are turned down and journals are ever less likely to accept publications outlining a new problem,” he said.

Prof Healy was speaking before an address to the one-day seminar: Mad Medicine: Do Conflicts of Interest Drive You Crazy? organised by the European Public Health Alliance, which will be held at University College Cork today.

According to Prof Healy, pharmaceutical companies are legally obliged to agree that their drugs may cause people to die by suicide while senior medical academics are not.

“And here is where they offer one of the greatest services they can to companies — they can and regularly do offer apologies for industry. They have become industry’s way around the law and any moral code that may apply in this domain,” Prof Healy said.

In his view, doctors reluctant to prescribe certain drugs because of anticipated adverse side-effects were likely to be accused of being a persecutor who victimises the patient by withholding effective treatment.

“Speaking up about a problem — once the material of medical advance — is now a recipe for professional suicide. When a doctor does report an adverse event to regulators, the report is invariably parked as uncertain and unreliable information,” he alleged.

The close relationship between some pharmaceutical companies and a percentage of the medical profession has previously been highlighted in highly critical independent reports by the Oireachtas Health Committee and its Westminster equivalent.

The April 2007 Oireachtas report by the cross-party group raised specific concerns over how some pharmaceutical firms regularly influence doctors through “hospitality” services.

The Adverse Side-Effects of Pharmaceuticals report, based on a similar document drawn up by MPs in Britain in 2004, said pressing issues needed to be addressedimmediately.

However, despite the serious concerns, one of the authors of the report, then Fine Gael TD Dr Liam Twomey, told the Irish Examiner in September 2008 that the findings had effectively been “shelved”.

Other speakers at the seminar include Labour MEP Nessa Childers, Prof Agnes Higgins of Trinity College Dublin and John McCarthy of Mad Pride.

GAITHERSBURG, Maryland (Reuters) – U.S. pediatric health advisers on Thursday urged drug regulators to continue studying weight gain and other side-effects of antipsychotic drugs as they are increasingly taken by children.

Significant numbers of U.S. children are receiving drugs to tame aggression, attention deficit disorder and other mental problems, even though there is little conclusive data to show exactly how the medications work or whether they damage kids’ health.

The pediatric advisory panel on Thursday listened to preliminary results of a study sponsored in part by the FDA that, inconclusively still, compared whether some antipsychotic drugs put children at a higher risk of developing diabetes than others.

Similar to the recommendations the panel has made in previous years, it voted 16-1 to support the U.S. Food and Drug Administration‘s routine safety monitoring of the new generation of antipsychotics.

But the panel did so with a caveat that the agency specifically look at how to clarify the drugs’ labels to highlight concerns about their impact on children, namely the risks of weight gain and diabetes.

“There is serious concern that children may be at a higher risk for serious adverse effects and we just don’t have sufficient data to answer that question,” said Dr. Jonathan Mink, a child neurology expert from the University of Rochester Medical Center.

Dr. Jeffrey Wagener, a pediatric pulmonologist from the University of Colorado Medical School, was the one adviser to vote “no” out of concern that wouldn’t get regulators closer to dealing with the risks of using antipsychotics in children.

“I don’t see how the FDA is responding to the December 8, 2009 request by this committee in a thorough fashion,” he said. “It’s taken them two years to not respond to that that we need to be more than in the observational role.”

The FDA in the next month to six weeks will release a revised label for Abilify, a drug sold by Bristol-Myers Squibb Co and Otsuka Pharmaceutical and approved to treat schizophrenia in adolescents, bipolar disorder in children 10 to 17 years old and irritability associated with autism in those as young as six.

“We ask that with this upcoming revision that you carefully consider the language around pediatric use and adverse events,” said Dr. Geoffrey Rosenthal, the committee’s chair and director of Pediatric and Congenital Heart Center at the University of Maryland Medical Center.

Abilify’s new label will detail the drug’s latest clinical trials, warn of metabolic concerns and remind doctors to monitor weight and symptoms of diabetes in all patients, said Dr. Thomas Laughren, FDA’s psychiatry products chief. The pediatric section of the label would contain a reference to those warnings, he said..

Such revisions, which are already incorporated into Johnson & Johnson‘s antipsychotic medication Invega Sustenna, are being considered for other similar drugs on a case by case basis, Laughren said.

The new generation of antipsychotic medications has raised a wave of concerns as they are increasingly being prescribed for a host of uses and for younger and younger patients, with little conclusive research addressing their impact on children and sometimes with little evidence they work.

Newer antipsychotics include J&J’s Risperdal, known generically as risperidone; Eli Lilly & Co’s Zyprexa or olanzapine; AstraZeneca‘s Seroquel or quetiapine; and Abilify, known generically as aripiprazole.

U.S. researchers have found that the drugs’ use in children increased by 65 percent from 2002 to 2009, primarily through prescriptions for teenagers.

From fall 2009 to spring of this year, 1.9 million prescriptions of Abilify alone were dispensed to patients under 18, including even 875 prescriptions for toddlers younger than 2, according to FDA research.

Most commonly, the prescriptions were for bipolar disorder in teenagers and preschoolers, and for affective psychoses in children between the ages of seven and 12.

Advisers also voted unanimously to require the FDA to show them label revisions and report back in the next year or 18 months on progress in designing more studies of the drugs in children.
