Item 1.01

Entry into a Material Definitive Agreement.

Roche Master Clinical Supply Agreement

On October 7, 2024, Tempest Therapeutics, Inc. (the “Company”) entered into a master clinical supply agreement (“Roche Supply Agreement”) with F. Hoffmann-La Roche Ltd. (“Roche”), pursuant to which Roche will supply Roche’s atezolizumab (TECENTRIQ) for use in one or more clinical studies conducted by the Company involving the Company’s proprietary compound amezalpat (TPST-1120) in combination with atezolizumab, in each case, in accordance with the applicable study protocol prepared by the Company and reviewed by Roche. Under the Roche Supply Agreement, the parties may execute one or more clinical supply agreement supplements (each, a “CSA Supplement”) that will set forth the study to be conducted by the Company, the quantities of atezolizumab to be supplied by Roche for such study, and the delivery timeline for such quantities of atezolizumab. Roche is obligated to supply to the Company the quantities of atezolizumab set forth in each applicable CSA Supplement in accordance with the terms of the Roche Supply Agreement. All data, results, and other information and reports generated in the performance of any study conducted under the Roche Supply Agreement will be solely owned by the Company, and the Company has certain specified obligations to provide Roche with summaries or copies of these data, results and reports.

On October 7, 2024, the Company and Roche entered into a CSA Supplement for Roche to supply atezolizumab to the Company, free of charge, for use in the Company’s planned phase 3 trial entitled “A Phase 3 Randomized, Double-Blind, Placebo-Controlled Study of TPST-1120 in Combination with Atezolizumab plus Bevacizumab Compared with Placebo plus Atezolizumab plus Bevacizumab in Patients with Unresectable or Metastatic Hepatocellular Carcinoma Not Previously Treated with Systemic Therapy.”

The Roche Supply Agreement may be terminated (i) by either party for convenience upon at least 60 days’ prior written notice to the other party (in which event, any existing CSA Supplement will remain in effect, unless separately terminated, and the Roche Supply Agreement will remain in effect solely with respect to such CSA Supplement until the study contemplated by such CSA Supplement is completed), (ii) by the non-breaching party if the other party is in material breach of the Roche supply Agreement and fails to cure such breach within 30 days after receipt of notice thereof from the non-breaching party, or (iii) by the non-acquired party if the other party undergoes a change of control. Each party may terminate a CSA Supplement if it experiences issues beyond its control that impacts its ability to supply its proprietary compound for the study contemplated by such CSA Supplement. Roche may terminate any CSA Supplement (a) if no patients have been treated with atezolizumab under the study contemplated by such CSA Supplement within one year of its effective date or (b) if Roche reasonably believes that atezolizumab is being used in an unsafe manner under the study contemplated by such CSA Supplement and the Company fails to address Roche’s concerns within a specified period. The Company may terminate any CSA Supplement for convenience or to protect patient safety. Each CSA Supplement may also be terminated as otherwise specified in such CSA Supplement.

The foregoing description of the Roche Supply Agreement is not complete and is qualified in its entirety by reference to the full text of such agreement, a copy of which will be filed, with confidential terms redacted, as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2024.
