What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new drug called aplitibart with standard chemotherapy and another drug in patients with metastatic colorectal cancer that has come back or spread. The treatment works by killing cancer cells and cutting off their nutrient supply.

Will I have to stop taking my current medications?

The trial requires that you stop taking any anti-cancer agents and certain other medications before starting the study treatment. If you are on medications that cause liver toxicity or have recently used chemotherapy or other specific treatments, you may need to stop those as well.

Is the combination of chemotherapy drugs with bevacizumab safe for treating colorectal cancer?

The combination of chemotherapy drugs like FOLFOXIRI or CAPOXIRI with bevacizumab has been studied for safety in treating colorectal cancer. Common side effects include diarrhea and neutropenia (low white blood cell count), but these are generally manageable. Overall, these combinations have shown an acceptable safety profile in patients with colorectal cancer. ^{1 2 3 4 5}

What makes the drug Aplitibart + Chemotherapy unique for colorectal cancer?

The combination of Aplitibart with chemotherapy for colorectal cancer is unique because it includes a mix of drugs like Azacitidine, Birinapant, and IGM-8444, which are not typically used together in standard treatments. This novel combination aims to target cancer cells more effectively by using different mechanisms of action, potentially offering a new approach for patients who may not respond to existing therapies. ^{4 6 7 8 9}

What data supports the effectiveness of the drug Aplitibart + Chemotherapy for Colorectal Cancer?

Research shows that irinotecan, a component of the treatment, significantly prolongs survival in patients with metastatic colorectal cancer when combined with other drugs like 5-fluorouracil and leucovorin. This combination is considered a standard treatment and has shown promising results in improving patient outcomes. ^{10 11 12 13 14}

Published Research Related to This Trial

In a study of 94 patients aged 70 and older with advanced colorectal cancer, both CAPOX and CAPIRI treatments showed similar overall response rates (38% for CAPOX and 36% for CAPIRI), indicating comparable efficacy as first-line treatments.

CAPOX was better tolerated than CAPIRI, with fewer severe side effects such as diarrhea and neutropenia, suggesting it may be a safer option for elderly patients.

Irinotecan has been shown to significantly prolong survival in patients with 5-FU-resistant colorectal cancer compared to best supportive care or 5-FU-based chemotherapy, based on Phase III studies.

Combining irinotecan with other treatments, such as raltitrexed or oral fluoropyrimidines, has shown promising results in terms of safety and efficacy, with response rates exceeding 30% and median survival benefits in various cancer types.

Irinotecan has been established as a standard treatment for advanced/metastatic colorectal cancer, showing survival benefits over best supportive care and 5-fluorouracil (5-FU) without negatively affecting patients' quality of life.

Combining irinotecan with oral capecitabine has shown promising results in terms of efficacy and safety, offering a more convenient treatment option compared to traditional infused 5-FU, and represents a potential new standard for first-line therapy.

The combination of FOLFIRI and aflibercept was found to be active and tolerable in treating metastatic colorectal cancer (mCRC), with an objective response rate of 46.6% among 73 patients, indicating potential effectiveness in this patient population.

Despite its activity, the regimen did not surpass historical benchmarks for efficacy in chemotherapy-naive patients, with a 12-month progression-free survival rate of only 21.9% and a median overall survival of 20.9 months, suggesting that while it may help some patients, it may not be a significant improvement over existing treatments.

The combination of FOLFOXIRI and bevacizumab demonstrated a promising progression-free survival (PFS) rate of 74% at 10 months in patients with unresectable metastatic colorectal cancer, based on a phase 2 study involving 57 patients.

The treatment was found to be safe, with no unexpected adverse events reported, although common serious side effects included neutropenia and hypertension, indicating that while effective, careful monitoring for these side effects is necessary.

The modified FOLFIRI regimen, which includes irinotecan, 5-fluorouracil, and a low dose of leucovorin, demonstrated a 47.8% overall response rate in 44 patients with recurrent or metastatic colorectal cancer, indicating its efficacy as a first-line treatment.

The treatment was well-tolerated, with mild and manageable toxicities; only a few patients experienced severe side effects, such as Grade 3/4 leukopenia and diarrhea, suggesting a favorable safety profile.

A phase II study involving 43 patients with advanced gastrointestinal tumors showed that capecitabine combined with either irinotecan or oxaliplatin is effective in treating colorectal and other GI cancers, demonstrating significant clinical activity as both first-line and salvage therapy.

The combination therapies exhibited an excellent safety profile, with manageable grade 3/4 toxicities primarily limited to diarrhea, and no severe myelosuppression observed, indicating that these regimens are safe for patients.

Irinotecan has shown significant activity against advanced colorectal cancer when combined with traditional chemotherapy agents like fluorouracil, leading to clinical responses including complete remissions in patients.

The combination therapies have acceptable toxicity profiles, with neutropenia and delayed diarrhea being the most common side effects, indicating that irinotecan could be a safe option for treatment, although further large-scale phase III studies are needed to confirm its benefits.

The evolution of chemotherapy for colorectal cancer has shifted from the single-agent use of 5-fluorouracil (5-FU) to more effective combination regimens that include irinotecan, oxaliplatin, and targeted agents like bevacizumab, significantly improving patient survival rates.

Combination therapies utilizing 5-FU as a base have been shown to enhance treatment outcomes, highlighting the importance of integrating newer drugs into established regimens for better management of colorectal cancer.
