What is the purpose of this trial?

This trial explores a new treatment, TYRA-200, to determine its safety and effectiveness for individuals with certain advanced cancers, such as bile duct cancer, that involve a specific gene change called FGFR2. The trial examines the drug's efficacy, its movement through the body, and any side effects. Suitable candidates have bile duct cancer that cannot be surgically removed, have tried other treatments without success, and possess a specific FGFR2 gene change that rendered previous treatments ineffective. Participants will take TYRA-200 orally once a day in 28-day cycles. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, it does mention that participants must have received a prior FGFR inhibitor, so you may need to continue with certain treatments.

Is there any evidence suggesting that TYRA-200 is likely to be safe for humans?

Research shows that TYRA-200, a new treatment for bile duct cancer, remains in the early testing stages. Limited information exists about its safety for people. Current studies focus on determining the right dose and identifying any side effects. These studies aim to ensure the treatment's safety for patients. In this Phase 1 trial, researchers primarily assess patient reactions and potential side effects. As research progresses, more detailed safety information will emerge. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

TYRA-200 is unique because it offers a new approach to treating bile duct cancer. Unlike traditional chemotherapy, which targets rapidly dividing cells and can affect healthy cells too, TYRA-200 works by specifically targeting cancer cells with a novel mechanism of action. Researchers are excited about this treatment because it is taken orally, making it easier for patients compared to intravenous therapies, and it may offer fewer side effects. This targeted approach could lead to more effective outcomes and better quality of life for patients with this challenging condition.

What evidence suggests that TYRA-200 might be an effective treatment for bile duct cancer?

Research has shown that TYRA-200 targets changes in the FGFR2 gene, often found in bile duct cancer. FGFR2 is a protein that can promote cancer growth when altered. TYRA-200 blocks these changes, potentially slowing or stopping tumor growth. Early studies have shown promising results in various cancers with FGFR2 changes. Although human studies have provided limited information, the mechanism of TYRA-200 suggests it could benefit people with FGFR2-related cancers. Participants in this trial will take TYRA-200 orally once daily in 28-day cycles. ^{1 2 3 4 6}

Trial Overview

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.

In a study of 61 patients with biliary tract cancers, CYFRA 21-1 demonstrated a higher sensitivity (80.3%) compared to CA 19-9 (68.9%) for detecting these cancers, making it a more reliable biomarker.

CYFRA 21-1 levels increased progressively with the stage of the disease, indicating its potential to help differentiate between early and advanced stages of biliary malignancy.

Bile survivin and carbohydrate antigen 199 (CA199) levels are significantly elevated in patients with cholangiocarcinoma, indicating their potential as biomarkers for this type of cancer.

The combination of bile survivin and CA199 improves the ability to differentiate cholangiocarcinoma from benign obstructive jaundice, with bile survivin showing a strong diagnostic capability (AUC of 0.780).
