CAMBRIDGE, Mass., Aug. 12, 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 second quarter 2021 financial results and provided a business update.

“We remain excited about the prospects for vidutolimod in melanoma, based upon compelling clinical data to date, as well as our expansion into new tumor types. We are focused squarely on execution of our clinical trials to deliver upon these opportunities, and we anticipate multiple clinical data readouts in 2022,” said Barry Labinger, President and Chief Executive Officer of Checkmate.

Second Quarter Business Update

  • Advancing patient recruitment activities and enrollment across our ongoing clinical trials evaluating vidutolimod, including:
    • A Phase 2 trial of vidutolimod in combination with nivolumab in anti-PD-1 refractory advanced melanoma, supported by a clinical collaboration with Bristol Myers Squibb.
    • A randomized Phase 2/3 trial of vidutolimod in combination with nivolumab vs. nivolumab monotherapy in first-line metastatic or unresectable melanoma, also supported by the clinical collaboration with Bristol Myers Squibb.
    • A Phase 2 trial of vidutolimod in combination with pembrolizumab in recurrent or metastatic squamous cell head and neck cancer. Interim data readouts anticipated beginning 1H 2022 and maturing throughout 2022.
  • Ongoing start-up activities for the planned expansion of the development program for vidutolimod into cutaneous squamous cell carcinoma and Merkel cell carcinoma, supported by a clinical collaboration with Regeneron to evaluate the combination of vidutolimod and Libtayo® (cemiplimab).

Second Quarter 2021 Financial Results

  • Research and development expenses (R&D): R&D expenses for the three months ending June 30, 2021 were $14.9 million, compared to $6.5 million for the same period in the prior year. This increase reflected a milestone payment of $4.0 million in the second quarter of 2021 triggered by initiation of patient dosing in our refractory melanoma trial, as well as increases in personnel and operating expense for the planning and execution of additional clinical trials with vidutolimod.
  • General and administration expenses (G&A): G&A expenses for the three months ending June 30, 2021 were $4.1 million, compared to $1.8 million for the same period in the prior year. This increase was primarily attributable to increases in personnel and operating expense incurred in connection with Checkmate operating as a publicly traded company.
  • Cash, cash equivalents and investments: Cash, cash equivalents and available-for-sale investments were $95.6 million as of June 30, 2021.
