What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of three drugs to treat advanced colorectal cancer. It targets patients whose cancer has spread or cannot be surgically removed. The drugs work together to kill cancer cells, block their growth, and help the immune system fight the cancer. Oxaliplatin is a new drug that has been recently added to initial treatments for advanced colorectal cancer.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have had anti-cancer therapy within 2 weeks before starting the study medication. It's best to discuss your current medications with the trial team.

Is the combination chemotherapy of TAS-102 and Bevacizumab safe for humans?

The combination of TAS-102 (trifluridine/tipiracil) and Bevacizumab has been studied for safety in patients with metastatic colorectal cancer. Common side effects include nausea and vomiting, and some patients may experience blood-related issues like neutropenia (low white blood cell count). However, with dose adjustments, this treatment is generally considered safe for use in humans. ^{1 2 3 4 5}

What makes the drug combination of Bevacizumab, Irinotecan, and TAS-102 unique for treating colorectal cancer?

This drug combination is unique because it combines TAS-102, a chemotherapy drug, with bevacizumab, which helps prevent the growth of blood vessels that feed tumors, offering a treatment option for patients who have not responded to standard therapies. It has shown to improve survival in patients with metastatic colorectal cancer, especially when other treatments have failed. ^{1 3 5 6 7}

What data supports the effectiveness of the drug combination of TAS-102 and bevacizumab for colorectal cancer?

Research shows that the combination of TAS-102 (trifluridine and tipiracil) and bevacizumab can improve survival in patients with metastatic colorectal cancer, especially those who have already tried other treatments. Studies have found that this combination can help patients live longer and delay the progression of the disease. ^{1 3 5 8 9}

Trial Overview The study tests a combination of TAS-102 (a chemotherapy drug), irinotecan (another chemo drug), and bevacizumab (an immunotherapy agent) in patients who've previously been treated for metastatic or unresectable colorectal cancer. The goal is to see if this combo is more effective than traditional treatments.

Patients receive irinotecan IV over 90 minutes and bevacizumab IV over 10 minutes on days 1 and 15. Patients also receive trifluridine and tipiracil hydrochloride PO BID on days 2-6 and 16-20. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Published Research Related to This Trial

In a study of 19 patients with metastatic colorectal cancer, the combination of biweekly TAS-102 and bevacizumab resulted in a median progression-free survival of 5.6 months and overall survival of 11.5 months, indicating its efficacy as a third-line treatment.

The treatment was generally safe, with only one patient experiencing severe neutropenia (grade 3 or more), suggesting that this combination therapy may effectively manage cancer while minimizing serious side effects.

Prospective Multicenter Phase II Study of Biweekly TAS-102 and Bevacizumab for Metastatic Colorectal Cancer. Ishizaki, T., Mazaki, J., Enomoto, M., et al.[2021]

In a phase II study involving 153 patients with unresectable metastatic colorectal cancer, the combination of trifluridine/tipiracil plus bevacizumab (TT-B) demonstrated a median progression-free survival (PFS) of 9.2 months, which was longer than the 7.8 months observed with capecitabine plus bevacizumab (C-B).

Both treatment regimens were well tolerated, but TT-B was associated with a higher incidence of severe neutropenia (47% vs. 5% for C-B), while C-B led to more cases of severe hand-foot syndrome (12% vs. 0%) and diarrhea (8% vs. 1%).

In a phase 1/2 trial involving 25 patients with heavily treated metastatic colorectal cancer, the combination of TAS-102 and bevacizumab showed promising activity, with a 16-week progression-free survival rate of 42.9%.

The treatment was found to have manageable safety, with the most common severe side effects being neutropenia and leucopenia, but no treatment-related deaths were reported, indicating that this combination could be a viable option for patients who have not responded to other therapies.

The combination of trifluridine/tipiracil (TAS-102) and bevacizumab is a feasible treatment option for patients with recurrent colorectal cancer, as demonstrated in two case studies.

No severe adverse events (≥Grade 3) were reported, aside from hematotoxicity, indicating a relatively safe profile for this late-line chemotherapy regimen.

Trifluridine/tipiracil (TAS-102) has a favorable safety profile for patients with metastatic colorectal cancer (mCRC), showing a low incidence of common adverse events like nausea, diarrhea, and fatigue, which can help improve patient adherence to treatment.

Oncology nurses play a crucial role in educating patients about managing treatment-related adverse events, which is essential for maintaining adherence to this oral chemotherapy regimen.

In a study of 57 patients with metastatic unresectable colorectal cancer treated with the combination of TAS-102 and bevacizumab, the incidence of nausea was 57.9% and vomiting was 17.5%, indicating that these side effects are common even after multiple treatment cycles.

Patients who had previously experienced nausea and vomiting from other treatments were found to be at a higher risk for similar side effects when treated with TAS-102 and bevacizumab, suggesting that prior treatment history is an important factor to consider in managing these symptoms.

In a study of 35 patients with refractory metastatic colorectal cancer, the combination of trifluridine/tipiracil (TAS-102) and bevacizumab showed a disease control rate of 51.6% and a median overall survival of 9.3 months, indicating its efficacy in this challenging patient population.

The treatment was generally safe, with the most common severe side effects being neutropenia, asthenia, and nausea/vomiting, but importantly, there were no treatment-related deaths reported.

In a phase 3 study involving 856 patients with unresectable metastatic colorectal cancer, trifluridine-tipiracil plus bevacizumab showed similar progression-free survival compared to capecitabine plus bevacizumab, with median times of 9.4 months and 9.3 months respectively.

The safety profiles of the two treatments differed significantly, with trifluridine-tipiracil plus bevacizumab leading to higher rates of neutropenia and anemia, while capecitabine plus bevacizumab was associated with more cases of hand-foot syndrome, indicating that both treatments have distinct safety considerations.
