Tyrosine Kinase Inhibitor

TYRA-200 for Bile Duct Cancer (SURF201 Trial)

Phase 1
Recruiting
Research Sponsored by Tyra Biosciences, Inc
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Phase 1 Part A: Any histologically confirmed advanced solid tumor with FGFR/FGF pathway alterations including FGFR gene mutations, fusions, and amplifications, as well as gene amplifications of FGFR ligands, who have exhausted or refused approved standard therapies
Phase 1 Part B: Presence of an FGFR2 kinase domain mutation that confers resistance to previous/other FGFR inhibitors; resistance mutations should be identified by a US Food and Drug Administration authorized/approved companion diagnostic or a Clinical Laboratory Improvement Amendments (CLIA) validated local test performed in a certified laboratory
Must not have
Has a serum phosphorus level > upper limit of normal (ULN) during screening that remains >ULN despite medical management
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
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to 5 years
Awards & highlights
No Placebo-Only Group

Summary

This trial tests a new drug to see if it can safely treat cancers with a specific gene mutation, including liver cancer.

Who is the study for?
Adults with advanced solid tumors, including intrahepatic cholangiocarcinoma with FGFR2 gene alterations who have tried or declined standard treatments. For Part B, they must have had a prior FGFR inhibitor and specific resistance mutations. Exclusions include significant past anti-FGFR therapy toxicity, high serum phosphorus despite treatment, eye conditions increasing risk of toxicity, uncontrolled heart disease, active brain metastases, GI issues affecting drug absorption, and pregnant or breastfeeding women.
What is being tested?
The trial is testing TYRA-200's safety and effectiveness against tumors with FGFR2 gene changes. Participants take the oral medication daily in 28-day cycles. The study has two parts: dose escalation (Part A) to find a safe dosage and dose expansion (Part B) to further assess its effects at that dosage.
What are the potential side effects?
Potential side effects of TYRA-200 may include liver problems (hepatotoxicity), eye toxicity risks for those predisposed to ocular conditions, gastrointestinal disturbances that could affect the drug's absorption or administration orally.
