Shares of Novartis were up more than 2 percent in midday trading Tuesday after the Swiss drugmaker reported better-than-expected results, as strong sales of new products and its leukemia drug Glivec helped offset full copycat competition for its former best-selling blood pressure pill Diovan.

Novartis CEO Joe Jimenez told CNBC's "Squawk Box" the company was able to weather the patent expiration thanks to sales of three new products: multiple sclerosis treatment Gilenya, leukemia drug Tasigna and breast cancer pill Afinitor. Each saw sales grow by more than 20 percent in the third quarter.
