The Indianapolis company announced initial results from the research on Thursday and said it plans to submit the drug, ixekizumab, to regulators in the first half of next year.

In the ixekizumab research, between 31 percent and 41 percent of the patients taking its drug achieved clear skin, according to the drugmaker.

Psoriasis is a chronic disease that occurs when a person's immune system speeds up the growth cycle of skin cells. The most common form, plaque psoriasis, creates raised, red patches on the skin.
Lilly shares climbed 6 cents to $62.07 Thursday before markets opened. The stock had climbed about 22 percent so far this year, as of Wednesday's close. The Standard & Poor's 500 index has climbed about 7 percent over the same span.
