WALTHAM, Mass., March 11 Decision Resources, one of theworld's leading research and advisory firms focusing on pharmaceutical andhealthcare issues, finds that Teva Pharmaceutical's Copaxone has the greatestpatient share among first- and second-line therapies, and falls short of MerckSerono/Pfizer's Rebif (by 0.2 percent) in third-line treatment. However, inall three lines of therapy, the interferon-beta drug class (Biogen Idec'sAvonex, Rebif, and Berlex's Betaseron) outpaces the altered peptide liganddrug class (consisting only of Copaxone) in patient share. Competitionbetween the two drug classes is fiercest in first-line therapy.

"The low volume of patient share attributed to Avonex or Rebif comparedwith Copaxone in first- and second-line treatment illustrates a significantdelay on the part of physicians and/or patients to engage in an interferon-beta therapy within a year of a patient's initial diagnosis for multiplesclerosis," said Madhuri Borde, analyst at Decision Resources. "However, themagnitudes of Rebif's first- and second-line patient shares suggest that somephysicians are treating the disease more aggressively than might be expected,as this high-dose, high-frequency agent reaches patient shares close to andsurpassing Avonex in first- and second-line treatment, respectively."

According to the new report entitled Treatment Algorithms in MultipleSclerosis, neurologists note that Copaxone's better short-term and long-termside-effect/safety profile, together with its lower rate of induction ofneutralizing antibodies, are critical reasons for choosing Copaxone instead ofAvonex, Rebif and Betaseron. Although Copaxone is administered daily, 23-28percent of neurologists we surveyed indicate that a key reason to prescribethe drug over any of the interferon-beta therapies is the drug's ability tofoster greater patient compliance, an attribute that is closely tied to theCopaxone's lower incidence of flulike side effects.
