3 Biotech Stocks That Soared This Week: Are They Buys?

Call it a grand finale.

Three biotech stocks saved their best for the last. In the final week of 2017, Ampio Pharmaceuticals (NYSEMKT: AMPE), Insys Therapeutics (NASDAQ: INSY), and Fate Therapeutics (NASDAQ: FATE) saw their share prices soar by 20% or more.

But what drove these biotech stocks higher? And are they still buys after the nice runs at the end of the year? Here's what you need to know about Ampio, Insys, and Fate.

Ampio Pharmaceuticals: Just what investors knee-ded

Ampio Pharmaceuticals stock skyrocketed 47% over the last week. This increase capped off a remarkable 357% gain in 2017, with most of the stock's increase occurring in December. What's behind Ampio's tremendous performance? Great news from a late-stage study of the company's lead candidate Ampion in treating severe osteoarthritis of the knee.

On Dec. 14, Ampio announced that Ampion met the primary and secondary endpoints in a phase 3 clinical trial. The company reported that 71% of patients taking the drug met the OMERACT-OARSI responder criteria, which assesses three core symptoms of osteoarthritis of the knee (pain, function, and patient's global assessment) as a single variable. In addition, patients receiving Ampion achieved statistically significant improvement in a composite endpoint of pain and function, as well as an increase in quality of life as measured by a patient global assessment.

These positive results were enough to send Ampio stock much higher immediately after the announcement, with the momentum continuing into the past week. The company's next steps are to present a more detailed analysis of the late-stage study results and submit Ampion for U.S. regulatory approval.

Insys Therapeutics: On the fast track now

Insys Therapeutics stock vaulted nearly 37% higher this week. It's been a huge comeback for the biotech. Insys stock was down more than 40% year to date at the beginning of December. Thanks to recent gains, Insys' share price actually finished up more than 4% for 2017.

The big news this week came from Insys' announcement that the U.S. Food and Drug Administration (FDA) had granted Fast Track designation to the company's cannabidiol (CBD) oral solution for treating rare genetic disorder Prader-Willi syndrome. But Insys is still in pre-clinical testing for its CBD product in the indication, with the company planning to begin an early stage study toward the end of the first quarter of 2018. I suspect there's more to the story for the biotech's big gains.
