Preliminary Prospectus

** Shares**

This is an initial public offering of shares of common stock of Kyverna Therapeutics, Inc. We are offering shares of our common stock.

Prior to this offering, there has been no public market for our common stock. It is currently estimated that the initial public offering price per share will be between $ and $ . We have applied to list our common stock on the Nasdaq Global Market under the trading symbol “KYTX.” We believe that upon the completion of this offering, we will meet the standards for listing on Nasdaq, and the closing of this offering is contingent upon such listing.

We are an “emerging growth company” and a “smaller reporting company,” each as defined under the federal securities laws, and as such, we have elected to comply with certain reduced reporting requirements for this prospectus and may elect to do so in future filings. See “Prospectus Summary—Implications of Being an Emerging Growth Company and a Smaller Reporting Company.”

Investing in our common stock involves a high degree of risk. See the section of this prospectus titled “Risk Factors” beginning on page 16 to read about factors you should consider before buying shares of our common stock.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Certain of our stockholders and their affiliates, some of which are affiliated with our directors, have indicated an interest in purchasing shares of common stock in this offering with an aggregate value of approximately $ million at the initial public offering price. However, because indications of interest are not binding agreements or commitments to purchase, the underwriters may determine to sell more, fewer or no shares in this offering to any of these parties, or any of these parties may determine to purchase more, fewer or no shares in this offering. The underwriters will receive the same underwriting discount on any shares purchased by these parties as they will on any other shares sold to the public in this offering.

We have granted the underwriters an option to purchase up to additional shares from us at the initial public offering price less underwriting discounts and commissions.

The underwriters expect to deliver the shares against payment to purchasers on or about , 2024.
