FTY720 Update
Posted: Thu Apr 30, 2009 10:09 am
Novartis AG said a study shows that 80-83 percent of patients taking its multiple sclerosis drug FTY720 are relapse-free compared to 69 percent of those on the leading current treatment.
Novartis, which is presenting new Phase III results to the American Academy of Neurology, said the data reinforces results announced in December that showed the annual relapse rate was 52 percent lower compared with patients taking Biogen's injectable multiple sclerosis drug Avonex.
It said full results from the so-called TRANSFORMS study would be submitted to a peer-reviewed journal in the next few months, adding regulatory filings were on track for the United States and European Union at the end of 2009.
Lead investigator Jeffrey Cohen said the trial showed that FTY720 "may provide patients with an alternative choice to currently available medications for treating relapsing-remitting multiple sclerosis".
Novartis AG and Germany's Merck KGaA are leading the charge to develop MS drugs that can be taken orally, rather than by infusion or injection, but the firms must persuade physicians and investors that the treatments are safe.
Novartis said serious adverse effects were reported in fewer than 2 percent of patients treated with FTY720 and said a role for the drug in the death of a patient in February could neither be confirmed nor ruled out.
It added that the safety profile of a 0.5 mg dose appeared to be better than the 1.25 mg dose.
"The results are statistically significant," said Vontobel analyst Andrew Weiss. "Somewhat comforting is the fact that no new safety concerns in the TRANSFORMS trial have emerged."
Novartis also presented longer-term results from a Phase II study that showed continued low relapse rates after four years of treatment, with no change in the safety profile.
FTY720 has been associated with potentially fatal infections, skin cancer and, recently, a case of haemorrhaging focal encephalitis, an inflammation of the brain with bleeding. It is unclear whether the drug was responsible for the events.
Merck's drug, Cladribine, has been linked to a reduction in white blood cells, which can lead to infection, and in January the company said four patients in a late-stage trial were diagnosed with cancer. It is also due to present study results at the neurology meeting in Seattle.
Earlier this year Merck said results of a late-stage trial showed Cladribine reduced the number of relapses per year by as much as 58 percent, compared with those taking a placebo.
Biogen is developing an oral MS drug, known as BG-12, but it is not as far advanced as the Merck or Novartis drugs.
