Trial Summary

What is the purpose of this trial?

This phase I trial investigates the side effects and best dose of talazoparib when given together with trifluridine/tipiracil for the treatment of patients with colorectal or gastroesophageal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Drugs used in the chemotherapy, such as trifluridine/tipiracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving talazoparib with trifluridine/ tipiracil may inhibit certain enzymes in the cells that are responsible for tumor cell growth.

Will I have to stop taking my current medications?

The trial requires that you stop any systemic cancer treatments at least 2 weeks before starting the study drugs, or 6 weeks if you were taking mitomycin C or nitrosourea. Other medications are not specifically mentioned, so it's best to discuss your current medications with the study team.

What data supports the effectiveness of the drug Trifluridine/Tipiracil + Talazoparib for gastroesophageal cancer?

Trifluridine/tipiracil has been shown to improve overall survival and disease control in patients with metastatic gastric and gastroesophageal junction cancer who have been treated with at least two prior therapies, as demonstrated in the TAGS trial. This drug combination did not negatively impact quality of life and was generally well-tolerated, providing a valuable treatment option for these patients.12345

Is the combination of Trifluridine/Tipiracil and Talazoparib safe for humans?

Talazoparib has been shown to have a manageable safety profile in patients with certain types of breast and prostate cancer, meaning it is generally safe for use in humans. However, specific safety data for the combination of Trifluridine/Tipiracil and Talazoparib in gastroesophageal cancer is not available from the provided research.678910

How is the drug Trifluridine/Tipiracil + Talazoparib unique for treating gastroesophageal cancer?

This drug combination is unique because it combines Trifluridine/Tipiracil, which has shown to improve survival in patients with advanced gastric cancer after multiple prior treatments, with Talazoparib, a PARP inhibitor that may enhance the effectiveness of cancer treatment by preventing cancer cells from repairing themselves.1231112

Treatment Details

Interventions

  • Talazoparib Tosylate
  • Trifluridine and Tipiracil Hydrochloride
Trial OverviewThe study is testing the combination of two drugs: trifluridine/tipiracil and talazoparib. Trifluridine/tipiracil is a chemotherapy drug that kills cancer cells or stops them from growing. Talazoparib blocks enzymes needed by tumor cells to grow. The goal is to find the best dose of talazoparib that can be given safely with trifluridine/tipiracil.

Findings from Research

Trifluridine/tipiracil (Lonsurf®) has been shown to significantly improve overall survival in patients with metastatic gastric cancer who have previously undergone at least two treatment regimens, as demonstrated in the phase III TAGS trial.
The treatment not only enhances survival and progression-free survival but also maintains health-related quality of life, with manageable side effects primarily related to blood cell counts and gastrointestinal issues.
Trifluridine/Tipiracil: A Review in Metastatic Gastric Cancer.Kang, C., Dhillon, S., Deeks, ED.[2020]
In the phase III TAGS trial involving 507 patients with metastatic gastric/gastroesophageal junction cancer, trifluridine/tipiracil significantly improved overall survival (4.6-6.1 months) and progression-free survival (1.9-2.3 months) compared to placebo, regardless of the type of prior therapy received.
The safety profile of trifluridine/tipiracil was consistent across different treatment subgroups, with similar rates of severe adverse events, indicating it is a safe option for patients who have undergone multiple prior treatments.
Effects of prior therapies on outcomes with trifluridine/tipiracil in patients with metastatic gastric/gastroesophageal junction cancer in a randomized phase III trial (TAGS).Shitara, K., George, B., Taieb, J., et al.[2023]
Trifluridine/tipiracil (TAS-102) has been approved for treating metastatic gastric and gastroesophageal junction adenocarcinoma after showing significant improvement in overall survival (5.7 months) compared to placebo (3.6 months) in a Phase III trial with patients who had undergone at least two lines of chemotherapy.
The treatment demonstrated a disease control rate of over 50% after eight weeks and did not impair quality of life, while the most common serious side effect was neutropenia, indicating a manageable safety profile.
