Full Year and Fourth Quarter 2013 Financial Results
, cash equivalents and marketable securities totaled $316.2 million as of December 31, 2013, compared to $66.2 million as of December 31, 2012. The cash increase was driven by net proceeds of $87.3 million from OncoMed's initial public offering in July 2013, and the upfront and equity payments of $177.25 million from the signing of the company's collaboration with Celgene in December 2013.
for the full year 2013 totaled $37.8 million, as compared to $24.7 million in 2012. Fourth quarter 2013 revenues were $19.0 million, compared to $6.9 million for the fourth quarter of 2012. The year-over-year and quarter-over-quarter increases were attributable to collaborative revenues in the form of milestone payments from Bayer associated with the vantictumab and OMP-54F28 programs received in the fourth quarter 2013 and the amortization of upfront payments from OncoMed's agreements with GSK, Bayer and Celgene.
Research and development (R&D) expenses
for the full year ended December 31, 2013, were $50.0 million compared with $39.9 million for the same period in 2012. For the fourth quarter of 2013 R&D expenses were $16.9 million, compared to $9.5 million for the fourth quarter of 2012. Increases in R&D expenditures during 2013 and the fourth quarter were primarily attributable to an increase in program costs associated with the advancement of OncoMed's clinical-stage product candidates and preclinical pipeline.
General and administrative (G&A) expenses
for the years ended December 31, 2013 and 2012, were $11.6 million and $7.2 million, respectively. For the fourth quarter of 2013 G&A expenses were $4.5 million, compared to $1.8 million for the fourth quarter of 2012. Increased costs for 2013 and the quarter ended December 31, 2013 were primarily attributable to higher one-time employee-related costs, higher legal fees associated with SEC filings and consulting fees from third-party vendors associated with public company operations and multiple business development activities.
for the year ended December 31, 2013 was $26.1 million ($1.93 per share), compared to $22.2 million ($21.30 per share, pre-IPO and reverse split) for the same period of 2012. The change in net loss for the year was due to an increase of collaboration revenue, more than offset by an increase in operational expenses, primarily research costs. Net loss in the fourth quarter of 2013 was the same for the fourth quarter 2012 at $4.3 million. Net loss per share available to common stockholders for the fourth quarter of 2013 was $0.15 per share, compared to $4.01 per share (pre-IPO and reverse split) for the fourth quarter of 2012.
