Consulting Services Agreement, dated August 31, 2022, by and between the Registrant and William P. Forbes

Exhibit 10.1

CONSULTING SERVICES AGREEMENT

This CONSULTING SERVICES AGREEMENT (this “Agreement”) is made as of the date of last signature (the “Effective Date”), by and between Trevi Therapeutics, Inc., a Delaware corporation with an address at 195 Church St., 14^th Floor, New Haven, CT 06510 (“Trevi”) and William Forbes, an individual with an address at 1008 Heydon Court, Raleigh,

NC 27614 (“Consultant”).

Trevi desires to retain Consultant to provide Services to Trevi and Consultant desires to provide those Services. Accordingly, the parties agree as follows:

1.1.Services. Subject to the terms of this Agreement, Consultant will provide consulting, advisory and related services as may be reasonably requested from time to time by Trevi, including, but not limited to, the services specified on Exhibit A (the “Services”). The manner and means by which Consultant chooses to perform the Services are in Consultant’s sole discretion and control. Consultant acknowledges that time is of the essence in performing the Services. Consultant may not subcontract or otherwise delegate Consultant’s obligations under this Agreement without Trevi’s prior written consent, and in the event Trevi gives such consent, Consultant will remain fully liable to Trevi for the performance of all permitted subcontractors.

2.1.Fees. In consideration for Services performed by Consultant, during the term of this Agreement, Trevi will pay the Consultant a monthly consulting fee of $15,000 per month (calculated on the basis of $375/hour for 40 hours per month), which fee shall be payable in arrears on the last day of each month. The fee will be pro-rated for any partial month. Although it is expected that Consultant will work approximately 40 hours per month, the monthly consulting fee is a fixed amount and shall not be subject to increase or decrease regardless of the number of hours expended in any given month by Consultant in the provision of the Services. However, the parties agree to evaluate the consulting fee from time to time as needed to adjust for use or non-use of Consultant’s services.

2.2.Expenses. Trevi will reimburse Consultant for reasonable and customary out-of-pocket business expenses incurred at the request of Trevi in the course of performing the Services (“Pass-Through Expenses”) provided: (i) Consultant provides receipts and descriptions for such expenses; and (ii) such expenses are permitted under any Trevi travel and expense policy currently in effect. Notwithstanding the foregoing, Trevi shall not reimburse Consultant for expenses incurred in any month that exceed $500.00 in the aggregate without the prior written approval of an executive officer of Trevi.

2.3.Invoices. Consultant will submit a monthly invoice to Trevi no later than 10 calendar days after the end of the month in which Services detailed in the invoice have been rendered or after incurring an authorized Pass-Through Expense. Consultant will include on the invoices the date and detailed description of the Services rendered and the Pass-Through Expenses incurred,

accompanied by original receipts. Trevi will pay all undisputed invoices within 30 days of receipt.

2.4.Stock Options. The parties agree and acknowledge that (i) in accordance with the terms of any stock options held by Consultant as of the date hereof that provide for time-based vesting (the “Options”) (and the option agreements evidencing the Options), any portion of the Options that are not vested as of the Effective Date shall continue to vest from and after the Effective Date for so long as Consultant continues to be a consultant and provide the Services hereunder and (ii) Consultant’s right to exercise the portion of the Options that are vested will terminate three months after the date Consultant ceases to be a consultant hereunder, provided that in the case of clause (ii) the vested Options may not be exercised after the Final Exercise Date (as defined in the option agreements evidencing the Options) or at all if, under the terms of the Options, Consultant’s rights to exercise the Options would have otherwise terminated immediately.

2.5.No Additional Consulting Benefits. Consultant agrees that he is not entitled to any benefits, coverages or privileges, including, without limitation, social security, unemployment, medical or pension payments, made available to employees of the Company or any other consideration or benefits from Trevi for the performance of the Services.

3.1.Definition. “Confidential Information” means information disclosed to Consultant by Trevi in the course of his service to the Company hereunder relating to Trevi’s business practices, financials, business plans, customer lists, strategies, plans, designs, products, processes, programs, trade secrets, know-how, technologies and inventions. Any of such information, in whatever form and whether or not marked as confidential or proprietary, and all derivatives, improvements and enhancements to any of the above, whether provided to Consultant, or created or developed by Consultant under this Agreement, as well as information of third parties as to which Trevi has an obligation of confidentiality, are all Confidential Information. Confidential Information does not include any information that Consultant can establish: (a) was publicly known or in the public domain prior to the time of disclosure to Consultant by Trevi; (b) becomes publicly known and made generally available after disclosure to Consultant by Trevi through no act or omission of Consultant; or (c) is approved for release by written authorization of Trevi.

3.2.Restrictions on Use and Disclosure. Consultant acknowledges the confidential and secret character of the Confidential Information, and agrees that the Confidential Information is the sole, exclusive and extremely valuable property of Trevi. Consultant will not use or reproduce the Confidential Information except as necessary in the performance of this Agreement and will not disclose any part of the Confidential Information in any form to any third party, either during or after the term of this Agreement, without the prior written consent of Trevi. Upon expiration or any termination of this Agreement, Consultant agrees to cease using and to return to Trevi, or at Trevi’s sole option, destroy, all whole and partial copies and derivatives of the Confidential Information, whether in Consultant’s possession or under Consultant’s direct or indirect control.

3.3.Permitted Disclosures. If Consultant is required by law, rule of court or regulation to make any disclosure that is prohibited by this Agreement, Consultant will, if legally permitted, provide Trevi with prompt written notice (email being sufficient) of such requirement prior to disclosure so that Trevi may seek a protective order or other appropriate relief. Subject to the foregoing sentence, Consultant may furnish that portion (and only that portion) of the Confidential Information that Consultant is legally compelled or is otherwise legally required to disclose. Any Confidential Information disclosed pursuant to the preceding sentence will continue to be treated as Confidential Information for all other purposes.

3.4.Third Party Information. Consultant will not disclose or otherwise make available to Trevi any confidential information received by Consultant under obligations of confidentiality from a third party.

3.5.Competitive Engagements. Consultant will provide prior written notice to Trevi if Consultant is to perform any services for a third party that develops, manufactures, promotes, sells, licenses, distributes, or provides products or services, or has plans to do any of the foregoing, that are substantially similar to or would compete with the technology, products or services of Trevi.

3.6.Non-Solicitation. During the term of this Agreement and for 12 months thereafter Consultant will not, directly or indirectly, on Consultant’s own behalf or on behalf of any third party: (a) solicit, encourage or induce any employee or consultant of Trevi to terminate his or her employment or engagement with Trevi; or (b) hire any person who was employed by Trevi during the 12 month period immediately prior to the effective date of termination of this Agreement; provided, however, that general public solicitations and advertisements not directed at employees of Trevi, and the extension of offers to persons who respond to such general solicitations and advertisements, will not be deemed violations of this provision.

3.7.Other Obligations. Consultant acknowledges and agrees that nothing herein, including Sections 3.5 and 3.6, shall be deemed to conflict with, supersede or terminate Consultant’s obligations to Trevi under the Non-Competition and Non-Solicitation Agreement between the parties (the “Non-Competition and Non-Solicitation Agreement”) and the Invention and Non- Disclosure Agreement between the parties (together with the Non-Competition and Non- Solicitation Agreement, the “Restrictive Covenant Agreements”). For clarity, except as provided in the Non-Competition and Non-Solicitation Agreement, the obligation of Consultant to comply with the non-competition and non-solicitation provisions set forth therein will conclude one year from the Effective Date.

4.1.Work Product; Assignment. Trevi will be the sole and exclusive owner of all right, title and interest in and to all inventions, notes, data, information, records, drawings, designs, discoveries, materials, and other deliverables, and any improvements to the foregoing that arise or are made, conceived and/or reduced to practice by Consultant in the course of providing the Services and all intellectual property rights in and to the Work Product, whether now known or hereafter recognized in any jurisdiction (collectively, “Work Product”). Consultant hereby

Such records are and remain the sole property of Trevi and upon Trevi’s request, Consultant will deliver the same to Trevi.

4.3.Assistance. Consultant agrees to execute all papers, including patent applications, invention assignments and copyright assignments, and otherwise agrees to assist Trevi, at Trevi’s expense, to perfect in Trevi the right, title and other interest in the Work Product. If Trevi is unable for any reason, after reasonable effort, to secure Consultant’s signature on any document needed in connection with the actions specified above, Consultant hereby irrevocably designates and appoints Trevi as Consultant’s agent and attorney-in-fact, which appointment is coupled with an interest, to act for and on Consultant’s behalf, to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes of this Section with the same legal force and effect as if executed by Consultant.

4.4.Background IP License.

In the event of any termination by Trevi, Consultant will cease work immediately after receiving notice of such termination unless otherwise advised by Trevi and will notify Trevi of all costs incurred up to the date of termination. If Trevi terminates this Agreement for convenience, Trevi will pay Consultant for all Services actually performed through the date of termination and will reimburse all reasonable, non-cancellable pre-approved costs and expenses incurred by Consultant in performing such Services. Sections 3 – 9 survive expiration or any termination of this Agreement, as does any other provision in this Agreement that by its nature and intent remains valid after the term.
