CAMBRIDGE, Mass., March 29, 2021 (GLOBE NEWSWIRE) — Checkmate Pharmaceuticals, Inc. (NASDAQ: CMPI) (“Checkmate”), a clinical stage biopharmaceutical company focused on developing its proprietary technology to harness the power of the immune system to combat cancer, today announced full year 2020 financial results and provided an update on recent progress.

“We made strong progress in 2020, laying the groundwork to broaden and accelerate our CMP-001 clinical program in melanoma and other solid tumor indications,” said Barry Labinger, President and Chief Executive Officer of Checkmate.

Recent Progress

• In December 2020, Checkmate announced a clinical collaboration with Bristol Myers Squibb to evaluate vidutolimod (formerly CMP-001) in combination with nivolumab. The companies will collaborate on two melanoma clinical trials.
• In January 2021, Checkmate appointed Robert F. Dolski as Chief Financial Officer. Mr. Dolski brings more than 20 years of diversified management experience as a life sciences financial executive.

Vidutolimod (formerly CMP-001) Anticipated 2021 Milestones

• Advance lead melanoma indication toward potential registration, supported by two Phase 2 trials. These trials will study vidutolimod in combination with nivolumab for the treatment of anti-PD-1 refractory melanoma and first-line metastatic or unresectable melanoma. We initiated patient dosing in the first-line melanoma trial in March 2021. Trial sites have been activated and patient screening is underway in the refractory melanoma study.  
• Expand into new indications, such as head and neck cancer, which is expected to be supported by a Phase 2 proof-of-concept trial. This trial will study vidutolimod in combination with pembrolizumab for the treatment of first-line head and neck cancer. Trial sites have been activated and patient screening is underway. Initial data from this trial are expected before the end of 2021.

Full Year 2020 Financial Results

• Cash, cash equivalents and investments: Cash, cash equivalents and investments were $125.9 million as of December 31, 2020.
• Research and development expenses (R&D): R&D Expenses for the full year 2020 were $26.7 million, compared to $24.3M for the prior year. The increase was primarily attributable to increased headcount and consulting costs in connection with preparing for the initiation of planned additional clinical trials of CMP-001. These increases were partially offset by a decrease in contract manufacturing costs.
• General and administration expenses (G&A): G&A expenses for the full year 2020 were $10.2 million, compared to $4.6 million for the prior year. The increase was primarily attributable to increases in personnel and other operating expenses incurred in connection with Checkmate beginning to operate as a publicly traded company.
• Net loss: Net loss for the full year 2020 was $36.9 million, compared to $28.3 million for the prior year.
