CAMBRIDGE, Mass., Aug. 11, 2016 (GLOBE NEWSWIRE) -- Dimension Therapeutics, Inc. (NASDAQ:DMTX), a biopharmaceutical company advancing novel, adeno-associated virus (AAV) gene therapies targeting the liver, a key organ for human metabolism, today reported financial results for the second quarter ended June 30, 2016, and provided an update on the company’s recent corporate progress.

Second Quarter 2016 Financial Results

  • Cash Position: Cash and cash equivalents as of June 30, 2016, were $104.7 million, compared with $127.0 million on December 31, 2015. Based on its current operating plan to fund seven programs, the company expects its existing cash and cash equivalents, payments received in connection with its collaboration agreement with Bayer and borrowing capacity under its loan and security agreement with Silicon Valley Bank will enable it to fund its operating expenses and capital expenditure requirements through Q1 2018.

  • Revenue: For the quarter ended June 30, 2016, Dimension recognized $2.4 million of revenue associated with our collaboration agreement with Bayer, compared to $1.7 million for the same period in 2015. The increase was due to services performed in connection with our performance obligations under the collaboration agreement with Bayer.

  • R&D Expenses: Research and development expenses for the quarter ended June 30, 2016, were approximately $11.2 million, compared to $9.4 million for the same period in 2015. The increase was primarily due to increased expenditures in advancing preclinical development and early clinical development of DTX301 (OTC deficiency) and manufacturing activity and early clinical development of DTX401 (GSDIa), offset by decreased expenditures in DTX101 (hemophilia B) as we transitioned from pre-clinical studies and manufacturing activities to clinical studies.

  • G&A Expenses: General and administrative expenses were $3.2 million for the quarter ended June 30, 2016, compared to $2.3 million for the same period in 2015. The increase was primarily due to increased personnel-related costs (including $0.4 million stock-based compensation), as a result of hiring additional full-time employees to support growth in operations, finance and human resources, increased professional fees associated with the costs of operating as a public company and costs related to general operations.

  • Net Loss: For the quarter ended June 30, 2016, the company reported a net loss of $(12.1) million, or $(0.49) per share, compared to a net loss of $(10.0) million, or $(2.57) per share, for the same period in 2015.
