What happened

After announcing that its phase 3 ATHOS-3 study would be published in a prestigious medical journal, clinical-stage biotech La Jolla Pharmaceutical (NASDAQ:LJPC) saw its shares jump by 24% as of 4 p.m. EDT on Thursday.

So what

La Jolla reported today that the full results of its ATHOS-3 phase 3 study of LJPC-501 will be published in The New England Journal of Medicine on May 21. This trial tested the efficacy of LJPC-501 in treating patients with catecholamine-resistant hypotension, or CRH, a life-threatening condition in which blood does not properly circulate throughout the body.

The clinical data from the trial showed that 70% of patients who used LJPC-501 were able to achieve their target blood pressure. That outcome was much better than the 23% of patients treated who reached their target from the placebo grouping.

However, when the ATHOS-3 data was released, some traders pointed out that the press release did not include any details about the study's secondary endpoint, which was to measure how LJPC-501 performed in reducing organ failure when compared to placebo. Traders appear to be bidding up shares today in anticipation of receiving the rest of the clinical data.

Now what

La Jolla had previously stated that it plans on sending LJPC-501 off for regulatory review in the second half of 2017. If everything goes according to plan, the drug could be on the market as soon as 2018. With analysts calling for LJPC-501 to potentially deliver peak sales in excess of $1 billion, there is a ton of pressure on this company to deliver a winning drug. Potential investors might want to wait to get a full look at the data before making an investment decision.
