Lilly seeks to block imports of cancer drug copy

Back to TopCommentsE-mailPrintBookmark and Share

Eli Lilly and Co. asked a U.S. trade agency on Thursday to block Hospira Inc. from selling a generic version of the cancer treatment Gemzar, saying the drug violates a patent on the process for making the active ingredient.

Lilly’s complaint to the U.S. International Trade Commission in Washington claims Hospira’s gemcitabine, Gemzar’s active ingredient, infringes a patent expiring in February 2014.

Global sales of Gemzar, used to treat lung, breast, pancreatic and ovarian cancer, fell about 14 percent to $905.8 million in the nine months ended in September, the Indianapolis-based company said Oct. 21.

Hospira began selling gemcitabine in November after Lilly lost an appeals court ruling that said a separate patent expiring in May 2013 was invalid.

The patented method is “the most commercially viable process available for manufacturing gemcitabine” and “involves less steps, higher yields and lower costs,” Lilly said in its complaint. Hospira has refused to provide records on the process it uses to make gemcitabine, according to the complaint.

Lilly is committed to protecting its intellectual property, Mark Taylor, a company spokesman, said in an e-mail Friday. Officials with Lake Forest, Ill.-based Hospira didn’t immediately return a message seeking comment.

The ITC has the power to bar imports of products that infringe U.S. patents and typically completes investigations in about 15 months.

Hospira sued Lilly in October. It’s seeking a court ruling that its process wouldn’t infringe the patent.

Lilly is facing generic competition for its three biggest products in the next two years: schizophrenia drug Zyprexa, antidepressant Cymbalta and the insulin Humalog. The three drugs generated $9.95 billion in 2009 sales, or about 46 percent of the company’s total revenue.

  1. The east side does have potential...and I have always thought Washington Scare should become an outlet mall. Anyone remember how popular Eastgate was? Well, Indy has no outlet malls, we have to go to Edinburgh for the deep discounts and I don't understand why. Jim is right. We need a few good eastsiders interested in actually making some noise and trying to change the commerce, culture and stereotypes of the East side. Irvington is very progressive and making great strides, why can't the far east side ride on their coat tails to make some changes?

  2. Boston.com has an article from 2010 where they talk about how Interactions moved to Massachusetts in the year prior. http://www.boston.com/business/technology/innoeco/2010/07/interactions_banks_63_million.html The article includes a link back to that Inside Indiana Business press release I linked to earlier, snarkily noting, "Guess this 2006 plan to create 200-plus new jobs in Indiana didn't exactly work out."

  3. I live on the east side and I have read all your comments. a local paper just did an article on Washington square mall with just as many comments and concerns. I am not sure if they are still around, but there was an east side coalition with good intentions to do good things on the east side. And there is a facebook post that called my eastside indy with many old members of the eastside who voice concerns about the east side of the city. We need to come together and not just complain and moan, but come up with actual concrete solutions, because what Dal said is very very true- the eastside could be a goldmine in the right hands. But if anyone is going damn, and change things, it is us eastside residents

  4. Please go back re-read your economics text book and the fine print on the February 2014 CBO report. A minimum wage increase has never resulted in a net job loss...

  5. The GOP at the Statehouse is more interested in PR to keep their majority, than using it to get anything good actually done. The State continues its downward spiral.
