Trial Summary

What is the purpose of this trial?

This is a two arm, 2-center, Phase II, study of 5-FU, irinotecan, bevacizumab (FOLFIRI-beva) and hydroxychloroquine (HCQ) in patients with previously untreated metastatic colorectal cancer (mCRC). Up to 155 patients will be screened for DTP-signature and up to 31 evaluable patients who are determined to be DTP-signature high will be treated with FOLFIRI-beva and HCQ. Patients will continue to receive treatments until evidence of disease progression, intolerable side effects, withdrawal of consent or death.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have received radiotherapy, chemotherapy, biological therapy, or investigational treatment less than four weeks before the first dose of the trial drugs.

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, if you have had recent treatments like chemotherapy or radiotherapy, you must wait at least four weeks before starting the trial.

What data supports the idea that Hydroxychloroquine + FOLFIRI + Bevacizumab for Colorectal Cancer is an effective treatment?

The available research shows that combining Bevacizumab with FOLFIRI (which includes drugs like 5-fluorouracil, leucovorin, and irinotecan) improves outcomes for patients with advanced colorectal cancer. Specifically, it increases the time patients live without the cancer getting worse and overall survival time. Studies have shown that adding Bevacizumab to these chemotherapy regimens significantly improves the response rate and delays tumor progression. However, the research does not specifically mention Hydroxychloroquine in combination with these drugs for colorectal cancer, so its effectiveness in this combination is not directly supported by the data provided. ^{1 2 3 4 5}

What data supports the effectiveness of the drug combination Hydroxychloroquine + FOLFIRI + Bevacizumab for colorectal cancer?

Research shows that Bevacizumab, when combined with FOLFIRI (a chemotherapy regimen including 5-fluorouracil, leucovorin, and irinotecan), significantly improves survival and slows disease progression in patients with metastatic colorectal cancer. This combination has been shown to be more effective than using 5-fluorouracil and leucovorin alone. ^{1 2 3 4 5}

What safety data is available for the treatment of Hydroxychloroquine + FOLFIRI + Bevacizumab in colorectal cancer?

The safety data for Bevacizumab, when used in combination with chemotherapy for colorectal cancer, indicates that it is generally well-tolerated. Common adverse effects include hypertension, proteinuria, arterial thrombosis, effects on wound healing, bleeding, and gastrointestinal perforation. These side effects are mostly mild to moderate and manageable, though some, like GI perforations and arterial thrombosis, occur less frequently. Bevacizumab-based chemotherapy has been shown to lower risks of dermatological and renal adverse events but increases cardiovascular risks such as hypertension and arrhythmia. Overall, Bevacizumab is considered a suitable adjunct to standard chemotherapy in colorectal cancer treatment. ^{6 7 8 9 10}

Is the combination of Hydroxychloroquine, FOLFIRI, and Bevacizumab safe for treating colorectal cancer?

Bevacizumab, when used with chemotherapy for colorectal cancer, is generally well-tolerated but can cause side effects like high blood pressure, protein in urine, and rare serious events like bleeding or gastrointestinal issues. The combination with FOLFIRI has shown manageable side effects, with some risk of cardiovascular issues. ^{6 7 8 9 10}

Is the drug combination of Bevacizumab, Fluorouracil, Hydroxychloroquine, Irinotecan, and Leucovorin promising for colorectal cancer?

Yes, the combination of these drugs, especially with Bevacizumab, has shown promise in treating metastatic colorectal cancer by improving treatment effectiveness when added to chemotherapy. ^{8 11 12 13 14}

What makes the Hydroxychloroquine + FOLFIRI + Bevacizumab treatment unique for colorectal cancer?

This treatment is unique because it combines hydroxychloroquine, which is typically used for conditions like malaria and autoimmune diseases, with a standard chemotherapy regimen (FOLFIRI) and bevacizumab, a drug that inhibits blood vessel growth in tumors. This combination aims to enhance the effectiveness of chemotherapy by potentially disrupting cancer cell survival mechanisms. ^{8 11 12 13 14}

Managing patients treated with bevacizumab combination therapy. Gordon, MS., Cunningham, D.[2015]

In a study of 1,401 patients with metastatic colorectal cancer, adding bevacizumab to first-line oxaliplatin-based chemotherapy significantly improved progression-free survival (PFS) from 8.0 months to 9.4 months compared to placebo.

While overall survival was longer in the bevacizumab group (21.3 months vs. 19.9 months), this difference was not statistically significant, indicating that while bevacizumab helps delay disease progression, it may not necessarily extend overall survival.
