What happened

Shares of Aurinia Pharmaceuticals (NASDAQ:AUPH) rose as much as 20% Tuesday morning after the company announced that it will present phase 2b data for its lead drug, voclosporin, at the National Kidney Foundation 2017 Spring Clinical Meetings in April. As of 11:36 a.m. EST, the stock had settled to gains of 19.2%.

The company's abstract was accepted as part of the "late-breaking" component of the meetings, which is a common mechanism for scientific gatherings that provides a way for conference organizers to balance advanced planning with the desire to include the most up-to-date events. Voclosporin only released data from the phase 2b trial evaluating its ability to treat lupus nephritis on the first day of this month.

So what

The lead drug not only met the 48-week endpoints for remission, but achieved the highest remission rate of any global lupus nephritis study ever completed. Both the low and high doses of voclosporin performed significantly better than the control arm, which is doubly important considering no drugs to date have shown a clear benefit for treating lupus nephritis.

Aurinia Pharmaceuticals announced that it would waste no time advancing the drug's development and initiate a phase 3 trial in the second quarter of 2017. Moreover, since the drug is intended to be used as a complement to standard care procedures, rather than completely upending standard care, it should have quick success in the market if it's eventually approved by regulators. An encore performance in a larger late-stage trial would make that a near-certainty.

Now what

Presenting at the National Kidney Foundation isn't necessarily important for Aurinia Pharmaceuticals stock in the near term, but it will introduce voclosporin to the very doctors that will be prescribing it if it successfully reaches the market. Investors are betting that approval is pretty likely after great phase 2b data, so they're considering this event to be a crucial step in laying the groundwork for a successful commercial launch. The optimism is certainly understandable, but keep in mind there is still over one year before regulators make a decision one way or the other.
