• Have received the following anticancer therapy:
  • Any immunotherapy or other antibody therapy within 28 days prior to the first dose of the study drug.
  • A TKI < 5 days or 5X the terminal Phase elimination half-lives, whichever is longer, prior to the first dose of TYRA-430.
  • Other systemic therapy not listed above < 14 days prior to the first dose of the study drug.
• Participant discontinued a prior anti-FGFR therapy due to significant toxicity
• Prior treatment with pan-FGFR inhibitors or FGFR4-selective inhibitors.
  • Part B, Cohort 2:
