It looks like most of the upside is already baked in. They have been really flying high lately.
For ITMN:

basically their drug Esbriet is approved in the EU and Canada. They have done 2 phase III studies already but the FDA made them do another one after rejecting approval in 2010. The outside FDA advisory Panel actually recommended they approve the drug and they went against that. Wall Street analysts are pegging chances of approval at 50-80%.
"The company’s revenue may more than double this year and next to about $130 million in 2014, analysts’ estimates compiled by Bloomberg show."
"The pressure will be on the FDA to clear the drug because no other treatments have been approved specifically for IPF in the U.S. yet, said Liisa Bayko, an analyst for JMP in San Francisco. At least 132,000 Americans have the disease and 40,000 die from it each year, according to the Pulmonary Fibrosis Foundation."
The stock price is down from over $18 on this news:

However, I find that these stocks always run up before Phase III study results which are coming out in Q2.
