Omeros Corp.’s phase III stumble in the busy immunoglobulin A nephropathy (IgAN) space put a sizeable dent in the stock (NASDAQ:OMER) and caused the Seattle-based firm to end the experiment with narsoplimab. Shares closed Oct. 16 at $1.54, down 73 cents, or 32%, after Omeros reported the interim analysis outcome of the trial called Artemis-IgAN.
Omeros Corp.’s complete response letter (CRL) from the FDA regarding its BLA for narsoplimab did not come as much of a surprise to Wall Street, but still was enough to drive shares (NASDAQ:OMER) down 26.6% to close Oct. 18 at $5.67, a loss of $2.06.
Shares of Omeros Corp. (NASDAQ:OMER) jumped 50.9% to $21.32 on Aug. 10 after it reported that six critically ill COVID-19 patients treated with its investigational lectin-pathway inhibitor, narsoplimab, recovered from the disease. The company said it will now seek government support to accelerate the drug’s large-scale manufacture. "We look forward to being able to make narsoplimab broadly available to hospitalized COVID-19 patients," said Omeros CEO Greg Demopulos.
A pivotal trial of Omeros Corp.'s narsoplimab, an investigational therapy for an occasional but serious complication of hematopoietic stem cell transplant (HSCT), found that just one dose was enough to deliver a beneficial effect in more than half the study's high-risk participants, meeting the study's primary endpoint.
