Schering-Plough seeks oks for Claritin-cousin drug
By Ransdell Pierson
NEW YORK., Oct 26 (Reuters) - Schering-Plough Corp. [SGP-news] said on Tuesday it has asked U.S. and European Union regulators to approve an allergy drug closely related to Claritin, its blockbuster which loses U.S. patent protection in 2002.
Schering-Plough said the experimental drug, desloratadine, is an active metabolite -- or chemically altered version -- of Claritin (loratadine). Claritin, a nonsedating antihistamine, is the New Jersey company's top-selling product, with global sales of $716 million in the third quarter of 1999.
Analysts have said Schering-Plough might extend the life of its Claritin franchise for up to a decade by launching a patent-protected new form of the drug, such as desloratadine -- particularly if it could demonstrate safety or efficacy advantages over Claritin.
Company spokesman William O'Donnell told Reuters he was unable to comment, for proprietary and regulatory reasons, on whether desloratadine indeed demonstrated any such advantages over Claritin in four large recently completed clinical trials.
"Desloratadine is a new chemical entity, a different drug than Claritin, that has been developed to extend the company's position in the allergy area," he said.
The separate U.S. and European Union marketing applications for desloratadine -- also a nonsedating, long-acting antihistamine -- are based on the four trials, Schering-Plough said.
O'Donnell said his company had licensed certain patent rights from Massachusetts biotech company Sepracor Inc. [SEPR-news] to sell desloratadine.
He said Schering-Plough and Sepracor each have different patents on desloratadine. Schering-Plough's "is a patent on the metabolite itself," or composition of matter patent, that expires in 2004, O'Donnell added.
Sepracor's patent on the metabolite, by contrast, covers its "method of use" in certain therapeutic areas and does not expire until 2014, a full decade after the expiration of Schering-Plough's patent on the experimental compound.
Sepracor specializes in developing altered and supposedly safer forms of existing drugs. It agreed in late 1997 to license its worldwide patents on desloratadine to Schering-Plough in exchange for undisclosed royalties that begin when the drug is launched commercially.
"The royalties (from Schering-Plough) to Sepracor will escalate over time upon achievement of sales volume of desloratadine and other milestones," O'Donnell said, declining to specify amounts.
Schering-Plough has been lobbying Congress to pass a controversial bill that would extend the patent life of Claritin three years beyond its looming 2002 expiration date.
Opponents of the bill, however, have argued the legislation would provide an undeserved windfall to Schering-Plough at the expense of allergy sufferers, who would have to wait longer for cheaper generic versions of Claritin.
Among other drugs Sepracor has developed is an altered form of Prozac, the blockbuster anti-depressant sold by Eli Lilly and Co. [LLY-news] . In Demember 1998 Lilly agreed to pay Sepracor $20 million up front plus up to $70 million in later payments for global rights to the Sepracor experimental compound. Lilly's last U.S. patent on Prozac expires in late 2003.
Shares of Schering-Plough were off 1-3/4 to 46-5/16 on the New York Stock Exchange. Sepracor was up 2-1/4 to 75 on the Nasdaq. |
