EXTON, Pa., March 12, 2020 (GLOBE NEWSWIRE) –Idera Pharmaceuticals, Inc., Inc. (“Idera”) (NASDAQ: IDRA) reported on March 11, 2020 its financial and operational results for the fourth quarter and year ended December 31, 2019.

“In 2019, we made great progress with ILLUMINATE-301, our registrational trial of tilsotolimod in combination with ipilimumab in anti-PD-1 refractory patients with advanced melanoma. This was the result of outstanding focus and dedication across our organization and enabled us to finish enrollment in the first quarter of 2020, earlier than anticipated. It also positions us to have initial data from the trial early next year,” stated Vincent Milano, Idera’s Chief Executive Officer. “2019 was also notable for our progress in taking tilsotolimod beyond melanoma through both our collaboration in squamous cell carcinoma of the head and neck and through our ILLUMINATE-206 trial, which we initiated in the microsatellite stable colorectal cancer cohort.”

Additionally, during the fourth quarter of 2019 the Company recorded $0.6 million and $11.0 million of non-cash warrant revaluation expense and non-cash future tranche right revaluation expense, respectively. These expenses were related to a private placement transaction consummated pursuant to a Securities Purchase Agreement, dated as of December 23, 2019, by and between us and certain institutional investors, whereby the Company sold shares of Series B1 convertible preferred stock and warrants to purchase common stock for $3.9 million and received an upfront option fee of approximately $6.2 million related to certain rights provided to such institutional investors to purchase shares of Series B2, Series B3, and Series B4 convertible preferred stock and warrants to purchase common stock in future tranches, subject to shareholder approval to increase authorized shares. The 2019 period also included non-cash deemed dividends of approximately $28.0 million, increasing net loss attributable to common stockholders, related to the transaction.

As a result of the factors above, net loss applicable to common stockholders for the three months ended December 31, 2019, was $51.3 million, or $1.76 per basic and diluted share, compared to net loss applicable to common stockholders of $12.2 million, or $0.45 per basic and diluted share, for the same period in 2018.  Net loss applicable to common stockholders excluding non-cash expense of approximately $11.6 million and deemed dividends of approximately $28.0 million related to the Securities Purchase Agreement for the three months ended December 31, 2019 was $11.7 million, or $0.40 per basic and diluted share.
