Rhea-AI Filing Summary
Trevi Therapeutics entered an underwriting agreement for an underwritten public offering of 11,600,000 shares of common stock at $13.00 per share, all sold by the company. Underwriters will buy the shares at $12.22 per share, and have a 30-day option to purchase up to 1,740,000 additional shares at the same terms.
Trevi estimates net proceeds of about $141.1 million, or $162.4 million if the option is fully exercised, to be raised under its effective Form S-3 shelf. It estimates cash, cash equivalents and marketable securities of approximately $171.8 million as of March 31, 2026, and believes existing cash plus offering proceeds will fund operations and planned Haduvio clinical trials through 2029, though not commercialization or all indications, so additional capital will still be required.

Insights
Trevi secures sizable equity funding to support multi-year Haduvio trials.
Trevi Therapeutics is executing a primary equity raise of 11,600,000 shares at $13.00 per share, with an underwriter option for 1,740,000 additional shares. Estimated net proceeds of up to $162.4 million sit alongside about $171.8 million of cash and marketable securities as of March 31, 2026.
The company states that this combined cash "will be sufficient" to fund operating expenses and capital expenditures through 2029, including two planned phase 3 IPF chronic cough trials and multiple phase 2b programs in non-IPF ILD and RCC. However, it explicitly notes these resources exclude commercialization costs and will not fund Haduvio to approval in all indications, implying future financings.
This financing reduces near- to medium-term funding risk around the development plan but introduces dilution from the new shares. Actual impact will depend on successful execution of the outlined trials and future regulatory feedback on Haduvio.

| Item 1.01 | Entry into a Material Definitive Agreement |
On April 16, 2026, Trevi Therapeutics, Inc., a Delaware corporation (the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”) with Morgan Stanley & Co. LLC and Leerink Partners LLC, as representatives of the several underwriters (the “Underwriters”), relating to an underwritten offering (the “Offering”) of 11,600,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”). All of the Shares are being sold by the Company. The price of the Shares to the public in the Offering is $13.00 per share, and the Underwriters have agreed to purchase the Shares from the Company pursuant to the Underwriting Agreement at a price of $12.22 per share.
Under the terms of the Underwriting Agreement, the Company granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 1,740,000 shares of Common Stock (the “Additional Shares”), at the same price per share as the Shares.
The Company estimates that the net proceeds from the Offering will be approximately $141.1 million, or approximately $162.4 million if the Underwriters exercise in full their option to purchase Additional Shares, in each case, after deducting underwriting discounts and commissions and estimated offering expenses.
The Offering was made, and the Shares and any Additional Shares will be issued pursuant to, the Company’s registration statement on Form S-3, as amended (File No. 333-291517), which became effective automatically upon filing with the Securities and Exchange Commission (the “SEC”) on November 13, 2025, a base prospectus dated November 13, 2025 forming a part of the registration statement on Form S-3, and a related preliminary prospectus supplement dated April 16, 2026. The closing of the Offering is expected to take place on or about April 20, 2026, subject to the satisfaction of customary closing conditions.
The Underwriting Agreement contains customary representations, warranties, covenants and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.
The foregoing description of the terms of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement, which is attached as Exhibit 1.1 hereto and is herein incorporated by reference. The foregoing description of the material terms of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.
A copy of the legal opinion and consent of Wilmer Cutler Pickering Hale and Dorr LLP relating to the Shares and the Additional Shares is attached as Exhibit 5.1 hereto.
This Current Report on Form 8-K shall not constitute an offer to sell, or the solicitation of an offer to buy, the securities discussed herein, nor shall there be any sale of such securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
| Item 2.02 | Results of Operations and Financial Condition |
The information disclosed under the heading “Cash, Cash Equivalents and Marketable Securities as of March 31, 2026” under Item 8.01 of this Current Report on Form 8-K is incorporated herein by reference.
| Item 8.01 | Other Events |
Press Release Announcing Pricing of Public Offering
On April 16, 2026, the Company issued a press release announcing the pricing of the Offering. A copy of the press release has been filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
Cash Runway
Based on the Company’s current plans, the Company believes that its existing cash, cash equivalents and marketable securities, together with the anticipated net proceeds from the Offering, will be sufficient to enable the Company to fund its operating expenses and capital expenditure requirements through 2029. The Company expects these cash resources will enable it to fund its development program for Haduvio for the treatment of chronic cough in patients with idiopathic pulmonary fibrosis (“IPF”), including its two planned Phase 3 trials, potentially through U.S. Food and Drug Administration (“FDA”) approval. The Company also expects that these cash resources will enable it to fund and report topline data from its planned Phase 2b clinical trial and potentially a subsequent Phase 3 clinical trial for the treatment of patients with non-IPF interstitial lung disease (“non-IPF ILD”)-related chronic cough, and its planned Phase 2b trial for the treatment of patients with refractory chronic cough (“RCC”). However, the Company’s planned spending of these resources does not include any commercial expenses related to the commercial launch of Haduvio or the conduct of any other clinical trials. In addition, these resources will not be sufficient for the Company to fund the clinical development of Haduvio through regulatory approval for non-IPF ILD-related chronic cough or RCC, or to fund any future product candidates through regulatory approval, and the Company will need to raise substantial additional capital to complete the development and commercialization of Haduvio and any future product candidates. The Company has based its estimates as to how long it expects it will be able to fund its operations and the timing and costs of its planned trials and regulatory process on assumptions that may prove to be wrong and the Company could use its available capital resources sooner than it currently expects, in which case the Company would be required to obtain additional financing, and its trials and regulatory activities may be delayed or take longer than it currently expects.
Business Update
The Company also provided a business update on its development programs for Haduvio for the treatment of chronic cough in patients with IPF, non-IPF ILD, and RCC. The Company previously announced its plans to conduct two pivotal Phase 3 clinical trials for the treatment of patients with IPF-related chronic cough. The Company plans to conduct the Phase 3 trials in parallel, with the first Phase 3 trial to be initiated in the second quarter of 2026 and the second Phase 3 trial to be initiated in the second half of 2026. The two Phase 3 trials will be conducted as randomized, double-blind, placebo-controlled, multicenter global trials with 2:1 randomization. The protocol for the first of the two Phase 3 trials provides for the enrollment of approximately 300 patients and 52 weeks of fixed dosing with Haduvio 54 mg twice-a-day (BID), with the primary efficacy endpoint measured at 24 weeks of fixed dosing and the safety endpoint measured at 52 weeks of fixed dosing. The protocol for the second of the two Phase 3 trials provides for the enrollment of approximately 130 patients and 12 weeks of fixed dosing with Haduvio 54 mg BID with the primary efficacy endpoint measured at 12 weeks of fixed dosing. The primary efficacy endpoint for both trials will be the relative change from Baseline in 24-hour cough frequency (coughs per hour), as determined by an objective cough monitor, for Haduvio compared with placebo. A key secondary endpoint for both trials will be relative change from Baseline in the cough severity numerical rating scale (CS-NRS). These trial designs are subject to final review of the protocols by the FDA. The Company expects to have topline results from the first Phase 3 trial in the first half of 2028 and from the second Phase 3 trial in the second half of 2027.
The Company also previously announced its plans to initiate an adaptive design Phase 2b clinical trial for the treatment of patients with non-IPF ILD-related chronic cough in the second half of 2026, subject to a meeting with the FDA and review of the trial protocol by the FDA. If the Company initiates the trial when anticipated, it would expect topline results from the Phase 2b trial in the second half of 2027.
Additionally, the Company previously announced its plans to initiate a Phase 2b trial of Haduvio for the treatment of patients with RCC in the second quarter of 2026. The Company is planning to conduct this randomized, double-blind, placebo-controlled, multicenter trial in the United Kingdom, Canada, and Poland. The Phase 2b trial will enroll approximately 100 patients. The Phase 2b trial is designed to evaluate three different dose groups of Haduvio (54 mg BID, 27 mg BID and 27 mg once daily (QD)) as compared to placebo. The primary efficacy endpoint for the trial is the relative change from Baseline in 24-hour cough frequency (coughs per hour) at the end of Week 6, as determined by an objective cough monitor, for Haduvio compared with placebo. The trial is subject to review of the protocol by regulatory authorities. The protocol provides for a sample size re-estimation, or SSRE, analysis, which is expected to occur in the fourth quarter of 2026 with topline results expected in the second half of 2027.
Cash, Cash Equivalents and Marketable Securities as of March 31, 2026
The Company estimates that it had approximately $171.8 million in cash, cash equivalents and marketable securities as of March 31, 2026.
The estimated figure above is based on preliminary information and represents management’s estimates as of the date of this Current Report on Form 8-K, is subject to completion of the Company’s financial closing procedures and does not present all necessary information for a complete understanding of the Company’s financial condition as of March 31, 2026, or the Company’s results of operations for the quarter ended March 31, 2026. The Company’s independent registered public accounting firm has not conducted a review of, and does not express an opinion or any other form of assurance with respect to, this preliminary estimate. This preliminary financial information should not be viewed as a substitute for full quarterly financial statements prepared in accordance with United States generally accepted accounting principles and reviewed by the Company’s independent registered public accounting firm.

About Trevi Therapeutics, Inc.

Haduvio is the first and only investigational therapy to show a statistically significant reduction in cough frequency in clinical trials across both patients with IPF chronic cough and in patients with RCC. Haduvio acts on the cough reflex arc both centrally and peripherally as a kappa agonist and a mu antagonist (KAMA), targeting opioid receptors that play a key role in controlling chronic cough. Nalbuphine is not currently scheduled by the U.S. Drug Enforcement Agency. Trevi intends to propose Haduvio as the trade name for oral nalbuphine ER. Its safety and efficacy have not been evaluated by any regulatory authority.
