Copaxone is still holding more than 40% of MS drugs market share.
What’s impressive is that Copaxone’s US share of patient Rx’s for MS has not changed to a significant degree from the launch of Gilenya or the uptake in Tysabri from JC-testing. Rather, Copaxone’s US share has remained at or near 40% for the past few years.
Teva forecasts $3.7-3.9B of worldwide Copaxone sales in 2013, which is a slight decrease from 2012. Teva has not given guidance on US Copaxone sales, specifically; however, if the historical 74% of sales in the US holds, then Teva expects 2013 US Copaxone sales of about $2.9B. The actual amount will depend on Copaxone price increases (which are a near certainty) and on competition from BG-12 and other oral agents.
Teva raises Copaxone price 10% (#msg-83178715), but this was already baked into Teva’s prior guidance, which implies about $2.9B of US Copaxone sales in 2013 (#msg-81977344).
