This free writing prospectus relates only to the offering described below and should be read together with the preliminary prospectus dated May 7, 2019 (the “Preliminary Prospectus”) included in Amendment No. 3 to the Registration Statement on Form S-1 (File No. 333-230745) of Trevi Therapeutics, Inc.  The Preliminary Prospectus can be accessed through the following link: https://www.sec.gov/Archives/edgar/data/1563880/000119312519138831/d643194ds1a.htm.

References to “Trevi,” “the company,” “we,” “us” and “our” are used in the manner described in the Preliminary Prospectus. The following information supplements and updates the information contained in the Preliminary Prospectus and primarily relates to an increase in the number of shares of common stock offered, a decrease in the assumed initial public offering price, a decrease in the estimated net proceeds from this offering, an increase in the indications of interest of certain of our existing stockholders, including certain of our directors, and their affiliated entities in purchasing shares of common stock in this offering and our entry into an agreement with New Enterprise Associates (“NEA”) pursuant to which NEA has agreed to purchase shares of our common stock in a separate private placement concurrent with this offering.

 

Common stock offered in this offering

   5,500,000 shares

Common stock offered in the concurrent private placement

   NEA has agreed to purchase $15 million in shares of our common stock at the initial public offering price per share (or 1,500,000 shares based on the assumed initial public offering price of $10.00 per share), subject to such offering price being no greater than $10.00 per share, in a private placement that is expected to close concurrently with, and is conditioned upon consummation of, this offering.

Common stock to be outstanding immediately following this offering and the concurrent private placement

   17,771,751 shares

Option to purchase additional shares

   We have granted the underwriters an option, exercisable for a period of 30 days after the date of the final prospectus relating to this offering, to purchase up to an additional 825,000 shares of our common stock.

Assumed initial public offering price

   $10.00 per share

Indications of interest to participate in this offering

   Certain of our existing stockholders, including certain of our directors, and their affiliated entities have indicated an interest in purchasing an aggregate of up to approximately $30 million in shares of our common stock in this offering at the initial public offering price and on the same terms and conditions as the other purchasers in this offering. However, because indications of interest are not binding agreements or commitments to purchase, the underwriters could determine to sell more, fewer or no shares to any of these potential purchasers, and any of these potential purchasers could determine to purchase more, fewer or no shares in this offering. The underwriters will receive the same underwriting discounts and commissions on any shares purchased by


   these parties as they will on any other shares sold to the public in this offering. The Preliminary Prospectus does not reflect any potential purchases by these potential purchasers. If any shares are purchased by our existing principal stockholders or their affiliated entities, the number and percentage of shares of our common stock beneficially owned by them after this offering will differ from the amounts set forth in the Preliminary Prospectus and in the section titled “Principal Stockholders” below.

Concurrent Private Placement

   NEA has agreed to purchase $15 million in shares of our common stock at the initial public offering price per share (or 1,500,000 shares based on the assumed initial public offering price of $10.00 per share), subject to such offering price being no greater than $10.00 per share, in a private placement that is expected to close concurrently with, and is conditioned upon consummation of, this offering. The shares to be sold in the concurrent private placement will constitute restricted securities under the Securities Act of 1933, as amended. The underwriters for this offering are serving as placement agents for the concurrent private placement and will receive a placement agent fee that is a percentage of the total purchase price of the private placement shares equal to the percentage underwriting discount the underwriters will receive on shares sold in this offering. The closing of this offering is not conditioned upon the closing of the concurrent private placement.

Dilution

  

After giving effect to (i) the automatic conversion of all outstanding shares of our convertible preferred stock and the accrued dividends on our convertible preferred stock into an aggregate of 10,198,224 shares of our common stock upon the closing of this offering (based on an assumed closing date of December 31, 2018 and giving effect to the issuance and sale of 6,849,315 shares of our Series C preferred stock for aggregate gross proceeds of $10.0 million in the third and final tranche of our Series C financing in January 2019), (ii) our issuance and sale of 5,500,000 shares of our common stock in this offering at the assumed initial public offering price of $10.00 per share, after deducting underwriting discounts and commissions and estimated offering expenses payable by us, (iii) our payment of a success fee to our former term loan lender that will become due as a result of this offering, (iv) the reclassification of deferred offering costs upon the completion of this offering and (v) our issuance and sale of $15 million in shares of our common stock at a price per share equal to the initial public offering price (or 1,500,000 shares based on the assumed initial public offering price of $10.00 per share) in the concurrent private placement to NEA, after deducting estimated placement agent fees payable by us, our pro forma as adjusted net tangible book value as of December 31, 2018 would have been $78.2 million, or $4.43 per share. This represents an immediate increase in net tangible book value per share of $2.80 to existing stockholders and immediate dilution of $5.57 per share in net tangible book value to new investors purchasing shares of our common stock in this offering.

 

If the underwriters exercise their option to purchase additional shares in full, our pro forma as adjusted net tangible book value per share would be $4.65 per share, representing an immediate increase in pro forma as adjusted net tangible book value per share of $3.02 to existing stockholders and immediate dilution of $5.35 per share to new investors purchasing shares of our common stock in this offering or the concurrent private placement, after deducting underwriting discounts and commissions, estimated placement agent fees and estimated offering expenses payable by us.


USE OF PROCEEDS

We estimate that the net proceeds from our issuance and sale of 5,500,000 shares of our common stock in this offering will be approximately $48.7 million, or $56.3 million if the underwriters exercise their option to purchase 825,000 additional shares in full, assuming an initial public offering price of $10.00 per share, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We also expect to receive net proceeds of $14.0 million from the sale of shares of our common stock to NEA in the concurrent private placement, after deducting estimated placement agent fees payable by us, for aggregate net proceeds to be raised by us in this offering and the concurrent private placement of $62.6 million.

As of December 31, 2018, we had cash and cash equivalents of $7.2 million. We currently estimate that we will use the net proceeds from this offering, together with our existing cash and cash equivalents, as follows:

 

   

approximately $7.5 million to $13.5 million to fund the development of nalbuphine ER for the treatment of pruritus associated with prurigo nodularis;

 

   

approximately $5.0 million to $7.5 million to fund the development of nalbuphine ER for the treatment of pruritus associated with chronic liver disease;

 

   

approximately $4.0 million to $8.0 million to fund the development of nalbuphine ER for the treatment of chronic cough in patients with IPF;

 

   

approximately $5.5 million to $7.5 million to fund the development of nalbuphine ER for the treatment of LID in patients with Parkinson’s disease; and

 

   

the remainder for working capital and other general corporate purposes.

We currently estimate that we will use the net proceeds from the concurrent private placement as follows:

 

   

approximately $2.5 to $4.0 million to fund the development of nalbuphine ER for the treatment of pruritus associated with prurigo nodularis;

 

   

approximately $1.0 to $1.5 million to fund the development of nalbuphine ER for the treatment of pruritus associated with chronic liver disease;

 

   

approximately $1.0 to $2.0 million to fund the development of nalbuphine ER for the treatment of chronic cough in patients with IPF;

 

   

approximately $1.5 to $2.5 million to fund the development of nalbuphine ER for the treatment of LID in patients with Parkinson’s disease; and

 

   

the remainder for working capital and other general corporate purposes.

Our expected use of the net proceeds from this offering and the net proceeds from the concurrent private placement and our existing cash and cash equivalents represents our intentions based on our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors, including the progress of our clinical development of nalbuphine ER, the status of and results from our clinical trials, including our ongoing PRISM trial as well as the additional Phase 3 clinical trial we will need to conduct for nalbuphine ER for pruritus associated with prurigo nodularis, the timing of regulatory submissions and the outcome of regulatory review, as well as any collaborations that we may enter into with third parties and any unforeseen cash needs. As a result, we

cannot predict with certainty the expenditures that may be necessary to complete the clinical development and commercialization of nalbuphine ER for any indication and our management will retain broad discretion over the application of the net proceeds from this offering and the net proceeds from the concurrent private placement.


Based on our current plans, we believe that the anticipated net proceeds from this offering and the net proceeds from the concurrent private placement, together with our existing cash and cash equivalents, will enable us to fund our operating expenses and capital expenditure requirements through the end of 2020. In particular, we expect that the anticipated net proceeds from this offering and the net proceeds from the concurrent private placement, together with our existing cash and cash equivalents, will enable us to complete our ongoing PRISM trial, our ongoing Phase 1b clinical trial in patients with chronic liver disease, our planned Phase 2 clinical trial for chronic cough in patients with IPF and our planned Phase 2 clinical trial for LID in patients with Parkinson’s disease. However, we do not expect these funds will be sufficient to complete the clinical development of nalbuphine ER for pruritus associated with prurigo nodularis and other indications, commercialize nalbuphine ER (if we receive regulatory approval) for pruritus associated with prurigo nodularis and other indications, and pursue the development and commercialization of any future product candidate. We do not have any committed external source of funds. Accordingly, we will be required to obtain further funding through public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources to complete the clinical development and commercialization of nalbuphine ER for pruritus associated with prurigo nodularis or any other indication.

Pending our use of the net proceeds from this offering and the net proceeds from the concurrent private placement, we intend to invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.

PRINCIPAL STOCKHOLDERS

The following table sets forth information with respect to the beneficial ownership of our common stock as of March 31, 2019 by:

 

   

each of our directors;

 

   

each of our named executive officers;

 

   

all of our directors and executive officers as a group; and

 

   

each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of our common stock (on an as-converted to common stock basis).

The column entitled “Beneficial Ownership Prior to this Offering and the Concurrent Private Placement” is based on a total of 10,771,751 shares of our common stock outstanding as of March 31, 2019, assuming the automatic conversion of all outstanding shares of our convertible preferred stock and the accrued dividends on our convertible preferred stock into an aggregate of 10,325,257 shares of our common stock upon the closing of this offering (based on an assumed closing date of March 31, 2019). The column entitled “Beneficial Ownership After this Offering and the Concurrent Private Placement” is based on 17,771,751 shares of our common stock to be outstanding after this offering and the concurrent private placement, including the 5,500,000 shares of our common stock that we are selling in this offering, assuming no exercise of the underwriters’ option to purchase additional shares in this offering, and 1,500,000 shares of our common stock that NEA has agreed to purchase in the concurrent private placement (based on the assumed initial public offering price of $10.00 per share).

Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options that are currently exercisable or exercisable within 60 days after March 31, 2019 are considered outstanding and beneficially owned by the person holding the options for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable. Except as otherwise set forth below, the address of each beneficial owner is c/o Trevi Therapeutics, Inc., 195 Church Street, 14th Floor, New Haven, Connecticut 06510.


Certain of our existing stockholders, including certain of our directors, and their affiliated entities have indicated an interest in purchasing an aggregate of up to $30 million in shares of our common stock in this offering at the initial public offering price and on the same terms and conditions as the other purchasers in this offering. However, because indications of interest are not binding agreements or commitments to purchase, the underwriters could determine to sell more, fewer or no shares to any of these potential purchasers, and any of these potential purchasers could determine to purchase more, fewer or no shares in this offering. The following table does not reflect any potential purchases by these potential purchasers. If any shares are purchased by our existing principal stockholders or their affiliated entities, the number and percentage of shares of our common stock beneficially owned by them after this offering will differ from the amounts set forth in the following table.
