In February 2019, the Company entered into an operating lease agreement for new office space in Philadelphia, Pennsylvania. The lease term commenced in May 2019 and was set to expire in July 2022. The initial annual base rent was $261, and increased by 2% annually on each anniversary of the commencement date. In February 2022, the Company amended this lease for an additional 35 months, through June 30, 2025. The annual base rent is $279, starting on January 1, 2023 and such amount will increase by 2.5% annually. The Company records rent expense on a straight-line basis over the lease term.


The Company’s lease for expanded lab space in Philadelphia, Pennsylvania commenced in the first quarter of 2022. This lease can be terminated by the Company with 90 days’ notice. The Company expects to utilize this space through June 30, 2025.

Rent expense related to these leases is recorded on a straight-line basis over the lease term. Rent expense recognized in the accompanying statements of operations was $170 and $68 for the three months ended March 31, 2022 and 2021, respectively.


In January 2021, the Company entered into a Development and Manufacturing Services Agreement (WuXi Agreement) with WuXi Advanced Therapies, Inc. (WuXi) to serve as the Company’s cell processing manufacturing partner for the planned MuSK-CAART Phase 1 clinical trial, or MusCAARTesTM trial. The Company concluded the WuXi Agreement has an embedded lease as a dedicated manufacturing suite is used for the Company’s cell processing manufacturing.

The Company recognized rent expense of $310 related to this lease in the accompanying statements of operations for the three months ended March 31, 2022. No rent expense was recognized for the three months ended March 31, 2021. The WuXi Agreement will expire the later of January 2024, or upon completion of WuXi’s services related to the MusCAARTesTM trial. The Company has the right to terminate the WuXi Agreement for convenience or other reasons specified in the WuXi Agreement upon prior written notice. If the Company terminates the WuXi Agreement, it will be obligated to pay an early termination fee of up to $1,500.

As of March 31, 2022, the future minimum payments for operating leases are as follows:

Research Service Agreement

In February 2021, the Company entered into a research service agreement with CHOP for vector manufacturing. In May 2021, this agreement was amended to provide additional vector manufacturing services. Research and development expense related to this research service agreement with CHOP recognized in the accompanying statements of operations was $166 and $222 for the three months ended March 31, 2022 and 2021, respectively. There was $333 due under this agreement as of March 31, 2022 included in Accounts payable in the accompanying balance sheets. This agreement has a remaining cost of $480, expected to be incurred in the first half of 2023.


Other Purchase Commitments

In the normal course of business, the Company enters into various purchase commitments with third-party contract manufacturers for the manufacture and processing of its product candidates and related raw materials, contracts with contract research organizations for clinical trials and agreements with vendors for other services and products for operating purposes. These agreements generally provide for termination or cancellation, other than for costs already incurred.  


The Company enters into certain types of contracts that contingently require the Company to indemnify various parties against claims from third parties. These contracts primarily relate to (i) the Company’s Amended and Restated Bylaws, as amended, (bylaws)

under which the Company must indemnify directors and executive officers, and may indemnify other officers and employees, for liabilities arising out of their relationship, (ii) contracts under which the Company must indemnify directors and certain officers and consultants for liabilities arising out of their relationship, (iii) contracts under which the Company may be required to indemnify partners against certain claims, including claims from third parties asserting, among other things, infringement of their intellectual property rights, and (iv) procurement, consulting, or license agreements under which the Company may be required to indemnify vendors, consultants or licensors for certain claims, including claims that may be brought against them arising from the Company’s acts or omissions with respect to the supplied products, technology or services. From time to time, the Company may receive indemnification claims under these contracts in the normal course of business. In addition, under these contracts, the Company may have to modify the accused infringing intellectual property and/or refund amounts received.

In the event that one or more of these matters were to result in a claim against the Company, an adverse outcome, including a judgment or settlement, may have a material adverse effect on the Company’s future business, operating results or financial condition. It is not possible to determine the maximum potential amount under these contracts due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement.

Pending Litigation

On February 28, 2022, a purported stockholder of the Company filed a complaint against the Company and certain of the Company’s current officers and certain of the Company’s current and former directors in the United States District Court for the Eastern District of Pennsylvania captioned Patterson v. Cabaletta Bio, Inc., et al.. No. 2:22-cv-00737 (E.D. Pa.). The complaint was filed on behalf of a putative class of persons and entities who purchased or otherwise acquired (a) Cabaletta common stock pursuant and/or traceable to the offering documents issued in connection with the Company’s October 24, 2019 initial public offering; and/or (b) Cabaletta securities between October 24, 2019 and December 13, 2021 both dates inclusive. The complaint alleges claims under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder and under Sections 11 and 15 of the Securities Act based upon allegedly false or misleading statements and omissions regarding our DesCAARTesTM Phase 1 clinical trial of DSG3-CAART, clinical data for the DesCAARTesTM trial, the efficacy of DSG3-CAART, and the clinical and/or commercial prospects for DSG3-CAART. The complaint seeks damages, prejudgment and post-judgment interest, and reasonable attorneys’ fees, expert fees and other costs. The Company may also become subject to additional securities class action lawsuits in the future. The Company intends to vigorously defend the lawsuit. At this time, no assessment can be made as to its likely outcome or whether the outcome will be material to the Company. No information is available to indicate that it is probable that a loss has been incurred and can be reasonably estimated as of the date of the financial statements and, as such, no accrual for the loss has been recorded within the financial statements.
