Collaboration revenues for the second quarter of 2013 were $2.9 million, compared to $7.5 million for the second quarter of 2012, a decrease of $4.6 million. This decrease was mainly a result of timing of a $5.0 million milestone payment that was achieved in the second quarter of 2012, offset by $0.4 million in collaboration revenue recognized in the second quarter of 2013 related to the amortization of a payment from Bayer received in August 2012.
Research and development expenses for the second quarter of 2013 were $10.5 million, compared to $9.6 million for the second quarter of 2012, an increase of $0.9 million. This increase was attributable to an increase in external program costs.
General and administrative expenses for the second quarter of 2013 were $2.0 million, compared to $1.7 million for the second quarter of 2012, an increase of $0.3 million. This increase was primarily attributable to higher legal fees and employee related costs, partially offset by lower consulting fees from third-party vendors.
OncoMed reported a net loss of $9.6 million for the second quarter of 2013, compared to $3.8 million for the second quarter of 2012. Net loss per share available to common stockholders for the second quarter of 2013 was $8.83 per share, compared to $3.64 per share for the second quarter of 2012. This increased net loss was mainly due to the timing of a $5.0 million milestone payment that was achieved in the second quarter of 2012.About OncoMed Pharmaceuticals OncoMed Pharmaceuticals is a clinical-stage company focused on discovering and developing novel therapeutics targeting cancer stem cells.
