Second Quarter Financial Results
For the second quarter ended June 30, 2021, Silverback reported a net loss of $24.5 million , compared to a net loss of $6.5 million for the comparable period in 2020. For the six months ended June 30, 2021, Silverback reported a net loss of $43.4 million , compared to a net loss of $11.7 million for the comparable period in 2020. Included in the net losses for the three and six months ended June 30, 2021 were $4.7 million and $9.0 million of non-cash stock-based compensation compared to $128,000 and $175,000 for the same periods in 2020.
Research and development expenses for the second quarter ended June 30, 2021 were $17.7 million , compared to $5.1 million for the same period in 2020. Research and development expenses for the six months ended June 30, 2021 were $30.0 million compared to $9.5 million for the same period in 2020. The increases in the Company’s research and development expenses in 2021 were primarily attributable to the advancement of pipeline programs, including SBT6290 and SBT8230, through preclinical development and the continued clinical development of SBT6050. Silverback also incurred additional personnel-related expenses as operations grew in support of program advancements.
General and administrative expenses for the second quarter ended June 30, 2021 were $6.8 million , compared to $1.3 million for the same period in 2020. General and administrative expenses for the six months ended June 30, 2021 were $13.4 million , compared to $2.2 million for the same period in 2020. The increases in general and administrative expenses were primarily attributable to an increase in personnel-related expenses due to increased headcount in 2021, including new executives, as well as increases in salaries, bonuses, and stock-based compensation. The increases in general and administrative expenses were also due to an increase in legal fees, professional fees, and other various general and administrative expenses as we now operate as a public company.
As of June 30, 2021, Silverback reported cash and cash equivalents of $359.7 million , compared to $386.6 million at December 31, 2020, which is expected to fund operating expenses and capital expenditure requirements for at least the next 24 months.
