Fingolimod

Schengen Agreement Disclosure: the editor of this blog, has been  perfomed and Health Evaluation Thecnology Assessment for Novartis, in 2011. Phase III studies shows heart blocks and  no one death. Eventhough Novartis has established a politic of control of at least 6 hours in a medical center. This policie is being supported by Novartis, at least in Argentina. The last pessure has shown that over almost 30K patients in treatment with the drug, just only one person died, and the conditions were no that the Novartis deals. I've signed a contract without restrictions to any relevant information. In spite of the prescrire statement, and I agree more studies are needed, but the quality of life is the strongest issue, being the first oral treatment that really equation risk/benefit is good enough (at the state of art today)  in multiple sclerosis. This statement has been written in order to encourage to all researchers, all over the world to declare their interest conflicts. The original paper has not been published yet. It has been writen in spanish, and my compromise is to ask to allow to Novartis to be published.

Fingolimod (Gilenya°): European Medicines Agency's lack of transparency spells danger for patients

The European Medicines Agency (EMA) has refused to supply Prescrire with the detailed data in its possession on cases of death which occurred following the first dose of  fingolimod (Gilenya°). This lack of transparency spells danger for patients.

Fingolimod (Gilenya°) is an immunosuppressant which has been authorised since March 2011 by the European Medicines Agency (EMA) for certain patients with multiple sclerosis. The pre-marketing evaluation data already revealed cardiac arrhythmia, among other disorders. In April 2011 Prescrire recommended limiting use of fingolimod to rigorously supervised clinical trials.
In December 2011, the US Food and Drug Administration (FDA) reported the sudden death of a patient within the first 24 hours of taking fingolimod. On 22 December 2011, in response to the FDA alert and faced with EMA’s silence, Prescrire asked EMA for a review of the serious adverse effects of  fingolimod, and for the initial European Periodic Safety Update Report (PSUR), which must be filed with EMA within 6 months of the marketing authorisation, i.e. in September 2011.
It was not until 20 January 2012 that the European Agency issued a public announcement on the subject, stating that there had been 3 other sudden deaths and 3 unexplained deaths. Three days later, on 23 January 2012, just 34 minutes before the legally mandated deadline, EMA informed Prescrire that its request for information dated 22 December was rejected, on the grounds that a European re-evaluation of fingolimod was under way: the re-evaluation had been initiated 3 days earlier.
On 7 February 2012, Prescrire reiterated its information request, this time to EMA Director Guido Rasi, vigorously contesting EMA’s grounds for refusal. As of 17 February 2012, EMA’s Director has not replied to Prescrire.
Once again the European Agency is refusing to provide patients and healthcare professionals with important information on adverse effects after the drug has come onto the market, information that is itself the fruit of the reporting work carried out by patients and healthcare professionals.
In May 2011, EMA had already invoked a re-evaluation under way to justify its refusal to provide Prescrire with information on pioglitazone (Actos°), which increases the frequency of bladder cancer and is no longer reimbursed by France’s national health insurance system. The European Commission has maintained the marketing authorisation for pioglitazone.
In early 2012, the European Medicines Agency and the European Commission’s Directorate General for Health and Consumers are behaving just as they did before the Mediator° fiasco. They give the benefit of the doubt to drug companies rather than to patients, and dispense information about adverse effects only sparingly. It is high time that they get back to their primary mission: protecting patients’ health, which should take precedence over protecting the financial interests of pharmaceutical companies.

Gilenya (fingolimod): Drug Safety Communication - Safety Review of a Reported Death After the First Dose

Gilenya (fingolimod): Drug Safety Communication - Safety Review of a Reported Death After the First Dose

AUDIENCE: Neurology, Patients
ISSUE: The FDA has received a report of a patie            nt with multiple sclerosis (MS) who died within 24 hours of taking the first dose of Gilenya (fingolimod). At this time, FDA cannot conclude whether the drug resulted in the patient's death. FDA is continuing to evaluate the case and will communicate any new information that results from this investigation.
BACKGROUND: Gilenya (fingolimod) is an oral medication for the treatment of relapsing forms of Multiple Sclerosis (MS) in adults. Gilenya is used to reduce the frequency of flare-ups (clinical exacerbations) and delay physical disability. 
RECOMMENDATION: At this time, FDA continues to believe that Gilenya provides an important health benefit when used as directed and recommends that healthcare professionals who prescribe Gilenya follow the recommendations in the approved drug label.  Patients with MS should not stop taking Gilenya without talking to their healthcare professional.
FDA will communicate any new information on Gilenya and this case when it becomes available.
Healthcare professionals and patients are encouraged to report adverse events or side effects related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:

Criterios Diagnóstico McDonald para Esclerosis Múltiple


Criterios Diagnóstico McDonald para Esclerosis Múltiple (EM)
Qué es un ataque?
  • Trastorno neurológico compatible con EM
  • Reporte subjetivo u observación objetiva
  • Duración mínima de 24 horas
  • Excluidos pseudoataques, episodios paroxísticos simples
Determinando el tiempo entre ataques
  • 30 días entre el comienzo del evento 1 y el comienzo del evento 2
Cómo es una "Anormalidad" en pruebas paraclínicas determinadas?
A- Imágenes de Resonancia Nuclear Magnética (RNM): Tres de cuatro:
  • 1 lesión que refuerza con Gadolinio (Gd) o 9 lesiones hiperintensas en T2 si no refuerzan con Gd
  • 1 lesión o más infratentorial
  • 1 lesión o más yuxtacortical
  • 3 lesiones o más periventriculares
(1 lesión de la médula espinal = 1 lesión cerebral)
B- Líquido cefalorraquídeo (LCR)
  • Banda oligoclonal IgG en LCR (y no en suero)
  • o índice IgG elevado
C- Potenciales evocados (PE)
  • Demorados pero con ondas de forma preservada
Qué evidencia provee la RNM de diseminación en tiempo?
Una lesión que refuerza con Gd demostrada en un estudio realizado por lo menos 3 meses después del comienzo del ataque clínico en un sitio diferente del ataque,
o 

En ausencia de lesiones que refuerzan con Gd en el estudio a los 3 meses, el estudio después de 3 meses adicionales muestra lesiones con Gd o nuevas lesiones en T2.
