WALTHAM, Mass. A drug made by Boehringer Ingelheim for treating Parkinson’s disease could have sales of up to half a billion dollars, according to a new analysis.
According to a report released Tuesday by market research firm Decision Resources, BI’s extended-release formulation of pramipexole will have peak-year sales of between $250 million and $500 million in major pharmaceutical markets. The drug was launched in Europe in 2009 and is expected to enter the market in the United States this year.
In the beginning, according to the report, launches of generic formulations of the immediate-release version of pramipexole and competition from GlaxoSmithKline’s and SkyePharma’s Requip XL (ropinirole CR) and generic versions of immediate-release Requip will put a damper on sales of pramipexole ER. However, physician familiarity with the drug and preference among physicians and patients for once-daily dosing will cause a “significant” increase in sales.
“Given physician comfort in prescribing pramipexole for Parkinson’s disease and the convenience of once-daily dosing that it would offer, we expect that pramipexole ER will take much of pramipexole IR’s patient share,” Decision Resources analyst Sami Fam said. “In the short term, we expect pramipexole ER will lose some patient share to ropinirole CR given that ropinirole CR was the first of the two agents to launch. But over the long term, physicians’ slight preference for pramipexole over ropinirole should help to boost pramipexole ER’s uptake.”
