Aurinia’s aritinercept shows promising results in phase 1 study

ROCKVILLE, Md. & EDMONTON, Alberta - Aurinia Pharmaceuticals Inc. (NASDAQ:AUPH) reported positive results from its Phase 1 single-ascending-dose study of aritinercept, a dual inhibitor of B cell-activating factor and a proliferation-inducing ligand, according to a company press release.

The study evaluated six different doses of aritinercept administered by subcutaneous injection in 61 healthy subjects. Results showed the drug was well tolerated across all dose levels with no treatment-related serious adverse events or discontinuations due to treatment-related issues.

The most common adverse events included injection site reactions (24% for aritinercept vs. 13% for placebo), headache (11% vs. 7%), upper respiratory tract infection (7% vs. 0%), and back pain (4% vs. 0%). All injection site reactions were classified as Grade 1.

Single doses of aritinercept demonstrated significant reductions in immunoglobulins, with mean decreases from baseline to Day 28 of up to 48% for immunoglobulin A, 55% for immunoglobulin M, and 20% for immunoglobulin G.

"Based on today’s positive results, which indicate robust and long-lasting pharmacodynamic effects supportive of once-monthly dosing, we plan to initiate clinical studies of aritinercept in at least two autoimmune diseases in the second half of this year," said Dr. Greg Keenan, Chief Medical Officer of Aurinia, in the press release. The company’s strong financial position, with more cash than debt on its balance sheet and a current ratio of 5.93, provides solid backing for these expansion plans.
