The Company leases office and laboratory space in Malvern, Pennsylvania under a noncancelable lease (the “Malvern Lease”). The Malvern Lease, which was concluded to be an operating lease, was amended in December 2020 to extend the term of the lease from May 2021 to May 2028. The Malvern Lease has annual scheduled payment increases and provides the Company a renewal option for an additional term of 60 months at the end of the lease term. The Company evaluates renewal options at lease inception and on an ongoing basis and includes renewal options that it is reasonably certain to exercise in its expected lease terms when classifying leases and measuring lease liabilities. As the Company is not reasonably certain to exercise the renewal option, the additional 60-month term has been excluded.

The Company's lease does not provide an implicit rate, and therefore, the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease. The Company used an incremental borrowing rate of 9.75% to discount the Malvern Lease payments included in the operating lease liabilities recognized.

The Company recognized $0.1 million and $0.2 million of lease cost during both the three and six months ended June 30, 2023 and 2022, respectively. Cash paid for amounts included in the measurement of operating lease liabilities was $0.1 million and $0.2 million for both the three and six months ended June 30, 2023 and 2022, respectively, and these amounts are included in operating activities in the consolidated statements of cash flows. As of June 30, 2023, the remaining lease term for the Malvern Lease is 5.0 years.

2024		366
2025		375
2026		383
2027		392
Thereafter		164
Total undiscounted future minimum lease payments	$	1,861
Less imputed interest		(394)
Total operating lease liabilities	$	1,467

As of June 30, 2023, $0.3 million representing the current portion of operating lease liabilities is included in accrued expenses and other current liabilities in the consolidated balance sheets and $1.1 million representing the long-term portion of operating lease liabilities is included in other long-term liabilities in the consolidated balance sheets.
