In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by providing the requested information and either submitting an amended draft registration statement or publicly filing your registration statement on EDGAR. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing the information you provide in response to these comments and your amended draft registration statement or filed registration statement, we may have additional comments. Draft Registration Statement on Form S-1 submitted August 20, 2021 Overview , page 1 1. Please remove the references throughout your prospectus to potential "first-in-class" or "best-in-class" product candidates as these descriptions imply an expectation of regulatory approval and are inappropriate given the length of time and uncertainty with respect to securing marketing approval. 2. We note your statements that VTX958 is a "potent" and "highly selective" tyrosine kinase type 2 inhibitor; that VTX958 has "leading selectivity profile and broad therapeutic window;" that VTX002 is a "potent" and "highly selective" sphingosine 1 phosphate receptor 1 modulator and "showed a robust, dose-dependent, steady-state reduction in ALC..."; that VTX958 has demonstrated a "wide safety margin"; that you are pursuing a Raju Mohan, PhD FirstName LastNameRaju Ventyx Biosciences, Inc. Mohan, PhD Comapany 18, September NameVentyx 2021 Biosciences, Inc. September Page 2 18, 2021 Page 2 FirstName LastName "promising therapeutic approach;" that you have developed a "potent" and "highly selective" NLRP3 inhibitor; that VTX2735 has demonstrated "potent NLRP3 inhibition;" that VTX2735 has demonstrated "potent in vivo pharmacodynamic activity," that "VTX2735 has a broad therapeutic window," and that you have a diversified pipeline of "promising product candidates." Please revise these and similar statements throughout your prospectus to eliminate conclusions or predictions that your product candidates are safe and effective, as determinations of safety and efficacy are solely within the authority of the FDA. You may provide an objective summary of the data that you used to draw these conclusions, and such discussion is more appropriate in the Business section where full and proper context can be provided. 3. We refer to the last two rows in your pipeline table. Please expand your disclosure in your Business section to provide a more fulsome discussion of these programs, including identifying the target and program for each product candidate as well as including a description of preclinical studies or other development activities conducted. Alternatively, please explain to us why these programs are sufficiently material to your business to warrant inclusion in your pipeline table. 4. Please revise your Summary to provide a brief description of your corporate organization and structure, including a discussion of your recent acquisitions of Oppilan Pharma Ltd. and Zomagen Biosciences Ltd. Our Competitive Strengths, page 2 5. We note your statements that you believe your deep internal drug discovery and development expertise and that you are able to "mitigate some of the risks usually associated with new product development." Please revise these and similar statements throughout your prospectus to remove any implication that you will be successful in advancing your product candidate in a rapid or accelerated manner and/or mitigate risk of unsuccessful clinical trials, as such statements are speculative and suggest that investors are afforded protection from loss. 6. Please provide the basis for your statements that all of your product candidates target multi-billion-dollar commercial markets, which you believe, to date, are unsatisfied. Our Management Team, Executive Chair, Advisors and Investors, page 3 7. Please limit the identification of investors in your summary and the discussion of "Our Management Team, Executive Chair, Advisors and Investors" beginning on page 100 to investors identified in your Principal Stockholders table on page 159. You may identify additional investors following the Principal Stockholders table with accompanying disclosure indicating any plans to update investors about any changes these entities make with respect to their investments in your company.

Here and in a risk factor at page 68, you state you have elected to take advantage of the extended transition period for complying with new or revised accounting standards under Section 107(b) of the JOBS Act.

To the extent the data in Table 1 on page 107 was not compiled based on head to head studies, please revise your disclosure to eliminate the comparison.

Please revise your statement on page 110 that "VTX958 can be dosed safely across the expected therapeutic range in humans" and your disclosure on page 120 that VTX2735 had an "attractive in vivo/in vitro safety profile" to avoid the implication that your product candidate is safe, as that determination is solely within the authority of the FDA and comparable regulatory bodies. We will not object to statements that your product candidate was well-tolerated in pre-clinical studies. Overview of the IBD Market Opportunity, page 111 19. We note your disclosure that in 2020, the IBD market was approximately $14 billion in the U.S. and $20 billion globally, with the UC segment representing approximately $7 billion in 2020 sales.
