MS Patients Perceive Copaxone Efficacy and Tolerability as Comparable to Rebif and Avonex

PatientsLikeMe Continues Report Series on Real-World Patient Experiences With Multiple Sclerosis Medications

CAMBRIDGE, MA--(Marketwire - Nov 3, 2011) - In the second report of a series on Multiple Sclerosis (MS) disease modifying therapies (DMTs), PatientsLikeMe reveals that MS patients perceive Copaxone as having comparable efficacy and tolerability profiles to the interferon therapies Avonex and Rebif. However, all three medications are perceived as trailing in efficacy and tolerability to Gilenya, Tysabri and Betaseron. In the report's analysis of 3,200+ patient conversations about MS DMTs from January-June this year, PatientsLikeMe also finds that Copaxone is perceived as safer than other MS DMTs.

"Patients' sharing of their Copaxone experience may adversely affect its demand as a first line therapy since patients are becoming more influential in their treatment decisions," says David S. Williams III, Chief Marketing Officer at PatientsLikeMe. "What has become clear through these reports is that real-world evidence will have a major impact on relative pricing for MS DMTs and play an increasingly important role in access decisions."

This 46-page report -- titled "Does Copaxone patient experience in the real world justify its value?" -- quantitatively and qualitatively analyzes 4,100+ MS patients with experience using Copaxone. Other report sections include:

  • The Patient Voice in Treatment Discussions: Copaxone was discussed in 25% of all patient conversations about MS DMTs.
  • Copaxone Efficacy and Side Effects: Of the 1,100+ MS patient evaluations on Copaxone's efficacy and side effects, 30% reported experiencing "moderate" to "major" efficacy, while 26% reported "moderate" to "severe" side effects.
  • Copaxone Price vs. Value: Is this medication appropriately priced compared to other MS DMTs given real-world evidence regarding efficacy and side effects?
