CAMBRIDGE, Mass., Feb. 27, 2014 (GLOBE NEWSWIRE) -- Merrimack Pharmaceuticals, Inc. (Nasdaq:MACK), a biopharmaceutical company discovering, developing and preparing to commercialize innovative medicines paired with companion diagnostics for the treatment of cancer, today announced its fourth quarter and full year 2013 financial results.

"We are pleased with the progress we made this past quarter advancing our therapeutic and diagnostic candidates," said Robert Mulroy, President and CEO of Merrimack. "We took a major step forward with the biomarker results for MM-121, which support our hypothesis on the importance of ErbB3 in cancer resistance. We also presented encouraging monotherapy and imaging data on MM-302. In addition, we made significant progress on the business development front, initiating a profit share collaboration with Actavis that has the potential to provide future cash flow to fund R&D."

Merrimack will host a conference call today, Thursday, February 27 at 4:30 p.m., Eastern Time, to provide an update on its development pipeline, focusing on MM-398, Merrimack's lead product candidate for which top line Phase 3 data is expected in the second quarter of 2014. The call will also provide a summary of fourth quarter and full year 2013 financial results.

Full Year 2013 Financial Results

Net loss for 2013 was $130.7 million, or basic and diluted net loss per share available to common stockholders of $1.32, compared with net loss for 2012 of $91.8 million, or basic and diluted net loss per share available to common stockholders of $1.28. This increase in net loss was primarily attributable to three factors:

  • $21.3 million of increased research and development expense primarily associated with Merrimack's clinical stage product candidates;
  • $10.4 million of increased interest expense from Merrimack's term loan with Hercules Technology Growth Capital, Inc., which closed in the fourth quarter of 2012, and from Merrimack's 4.50% convertible senior notes, which were issued in July 2013, of which $3.7 million is imputed non-cash expense primarily related to the convertible feature of the convertible senior notes; and
  • $5.4 million of increased general and administrative expense primarily associated with increased headcount costs to support clinical development, increased rent expense and increased costs to support commercialization efforts on MM-398.

As of December 31, 2013, Merrimack had $155.2 million of cash and cash equivalents and available-for-sale securities, which represents an increase of $45.2 million from the year ended December 31, 2012, due primarily to the July 2013 concurrent underwritten public offerings of 5.75 million shares of common stock at a price to the public of $5.00 per share and $125.0 million aggregate principal amount of 4.50% convertible senior notes. Combined net proceeds, after deducting underwriting discounts and commissions and other offering expenses, were $147.3 million. The total number of Merrimack's common shares outstanding as of December 31, 2013 was 102,523,262.

Financial Outlook

Merrimack expects its existing unrestricted cash and cash equivalents and available-for-sale securities as ofDecember 31, 2013 of $155.2 million, anticipated interest income and reimbursement of expenses under its license and collaboration agreement with Sanofi related to MM-121 to be sufficient to fund operations into 2015. In the event that Merrimack obtains favorable results from the MM-398 NAPOLI-1 trial, Merrimack expects that anticipated additional expenses in 2014 related to the commercialization of MM-398 will be offset by cash received from potential collaboration opportunities.
