PHASE1

Brief Summary

A Phase 1 study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamic (PD), and preliminary antitumor activity of TYRA-430 in cancers with FGF/FGFR pathway aberrations, includin...

This is an open-label, multi-center, first-in-human, Phase 1 global study of TYRA-430, a first-in-class, selective, reversible fibroblast growth factor receptor (FGFR) 4 and 3 inhibitor, in locally ad...

Eligibility Criteria

Inclusion

  • Key
  • All Patients:
  • Age ≥ 18 years
  • Eastern Cooperative Oncology Group (ECOG) performance status of ≤1.
  • Adequate end organ function.
  • Ability to swallow oral formulations.
  • Ability to understand and willingness to sign the ICF.
  • Part A:
  • Histologically confirmed locally advanced unresectable/metastatic HCC or histologically confirmed advanced solid tumor with documented FGF/FGFR pathway alterations
  • For participants with histologically confirmed locally advanced or metastatic HCC:
  • Barcelona Clinic Liver Cancer (BCLC) stage B that is not eligible for locoregional therapy, or stage C.
  • Child-Pugh Score class A
  • Must have previously received SOC appropriate for their tumor type. Any number of prior therapies, including FGFR inhibitors, are permitted.
  • Agree to provide archival tumor tissue no older than 2 years from the time of enrollment, if available. If an archived specimen is not available, a biopsy is not required.
  • Part B, Cohort 1:
  • Histologically confirmed locally advanced/metastatic HCC who have previously received standard of care.
  • Barcelona Clinic Liver Cancer (BCLC) stage B that is not eligible for locoregional therapy, or stage C.
  • Child-Pugh Score class A
  • Availability of an archival formalin-fixed paraffin-embedded (FFPE) tumor tissue specimen obtained ≤2 years prior to screening for submission to sponsor-designated central laboratory for FGF19 IHC testing.
  • At least 1 measurable lesion by RECIST v1.1.
  • Part B, Cohort 2:
  • Histologically confirmed advanced solid tumor except FGFR3-altered urothelial carcinoma and primary central nervous system tumors who have previously received standard of care. Note: Participants with confirmed diagnosis of locally advanced or metastatic HCC are not eligible for Cohort 2.
  • Must have an eligible activating gain-of-function alteration in the FGFR3 or FGFR4 gene, or focal amplifications of FGF19
  • Archival tumor tissue biopsy specimen no older than 2 years from the time of enrollment, if available. If a tissue biopsy specimen is not available, a biopsy is not required.
  • At least 1 measurable lesion by RECIST v1.1.
  • Key

Exclusion

  • All Patients:
  • Have disease that is suitable for local therapy administered with curative intent.
  • Have not recovered from reversible toxicity of prior anticancer therapy to \< Grade 1 or baseline (except toxicities that are not clinically significant or not expected to resolve, including but not limited to, alopecia, fatigue, skin discoloration, or Grade 1 neuropathy).
  • 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, defined as hepatotoxicity ≥ Grade 3 or any Grade 4 toxicity according to CTCAE v5.0.
  • Has a serum phosphorus level \> upper limit of normal (ULN) during screening that remains \>ULN despite medical management.
  • History of or current uncontrolled cardiovascular disease.
  • Active, symptomatic, or untreated brain metastases.
  • Have a diagnosis of primary CNS malignancies.
  • Gastrointestinal disorders that will affect oral administration or absorption of TYRA-430.
  • Females who are pregnant, breastfeeding, or planning to become pregnant and males who plan to father a child while enrolled in this study.
  • Any reason that, in the view of investigator, would substantially impair the ability of the participant to comply with study procedures and increase the risk to the participant.
  • Part B, Cohort 1:
  • Known fibrolamellar HCC, sarcomatoid HCC, or mixed cholangiocarcinoma and HCC.
  • Prior treatment with pan-FGFR inhibitors or FGFR4-selective inhibitors.
  • Part B, Cohort 2:
  • Histologically confirmed locally advanced/metastatic HCC.
  • Histologically confirmed urothelial cancer.
