Depreciation and amortization expense for the years ended December 31, 2023 and 2022 was $56,000 and $71,000, respectively.

In November 2023, the Company decided not to renew the lease for its corporate headquarters and primary research facility in Marlborough, Massachusetts. Beginning in April of 2024, we expect to continue operations as a remote business with a small laboratory facility. Based on this evaluation, the Company determined that long-lived assets with a carrying amount of $126,000 were no longer recoverable and an impairment charge of $126,000 was recorded to write those assets down to their fair value. The Company did not record any impairment charges at December 31, 2022.
