Why Nektar Therapeutics Shares Jumped

Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Nektar Therapeutics , a clinical-stage biopharmaceutical company, shot higher by as much as 11% after reporting positive top-line results for experimental drug NKTR-181 to treat chronic pain.

So what: NKTR-181, an opioid designed to enter the brain slowly so as to significantly lower the chances of addiction associated with most pain medications, showed significant statistical significance from oxycodone, a widely abused pain medication, in a human abuse liability study. In the study, patients didn't have nearly the same desire to abuse NKTR-181 as demonstrated by its lower "drug liking" and "feeling high" scores relative to oxycodone.

Now what: Obviously, the treatment of moderate-to-severe chronic pain is a big market. Unfortunately, the Food and Drug Administration has kept a very tight watch over new drug entrants because of the high propensity for abuse of these medications. If NKTR-181 can continue to show that its slower release reduces the want to abuse the drug while delivering a non-inferior benefit in terms of pain management, then it could certainly put Nektar on the map. For now, though, I'd consider adding Nektar to your personal watchlist.
