What side effects are associated with this type of intervention?

Common treatments for colorectal cancer include chemotherapy regimens such as oxaliplatin-based therapies and fluoropyrimidines (e.g., fluorouracil and capecitabine). These treatments are associated with side effects like neuropathy, hand-foot syndrome, diarrhea, nausea, vomiting, stomatitis, fatigue, and partial alopecia. Immunotherapy options, such as PD-1 inhibitors like Dostarlimab, can cause immune-related adverse events including pneumonitis, rash, pruritus, and endocrine disorders. Severe adverse effects are less common but can include severe infections and organ-specific toxicities.

What prior FDA approvals exist?

The FDA has approved several immunotherapy drugs for the treatment of colorectal cancer, particularly for cases with specific genetic markers such as dMMR (defective mismatch repair) or MSI-H (microsatellite instability-high). Pembrolizumab (Keytruda) and nivolumab (Opdivo) are PD-1 inhibitors approved for metastatic colorectal cancer that has progressed following prior treatment. These approvals are based on the efficacy of these drugs in targeting the PD-1 pathway, which helps the immune system recognize and attack cancer cells. The trial of dostarlimab, another PD-1 inhibitor, is being studied for its potential in treating resectable colon cancer with similar genetic markers.

What other types of research exist?

Promising alternatives to Dostarlimab for colorectal cancer patients include Pembrolizumab and Nivolumab, both of which are PD-1 inhibitors. Additionally, combination therapies involving PD-1 inhibitors with chemotherapy, such as Pembrolizumab plus FOLFOX, are being explored and show potential. Emerging therapies like personalized antibodies and novel immunotherapy combinations are also under investigation and may offer new options in the near future.

Summary

This trial is testing dostarlimab, a drug that helps the immune system fight cancer. It targets patients with a specific type of colon cancer that has certain genetic features and can be surgically removed. Dostarlimab works by helping the immune system recognize and destroy cancer cells.

Who is the study for?

This trial is for individuals with untreated T4N0 or Stage III colon cancer that can be surgically removed and shows either dMMR status or MSI-H. Participants should not have had any prior treatments for colon cancer, no distant metastatic disease, and must not require urgent surgery due to bowel obstruction.

What is being tested?

The study tests the effectiveness of dostarlimab given around the time of surgery compared to standard chemotherapy regimens (CAPEOX or FOLFOX) in patients with specific types of resectable colon cancer. The goal is to see if dostarlimab improves outcomes.

What are the potential side effects?

Dostarlimab may cause allergic reactions, immune-related issues like inflammation in organs, fatigue, digestive problems, skin reactions, and could potentially worsen pre-existing conditions such as lung disease.

Other Research

The most common treatments for colorectal cancer include chemotherapy, targeted therapies, and immune checkpoint inhibitors. Chemotherapy drugs, such as fluorouracil, oxaliplatin, and irinotecan, work by interfering with the DNA replication process, thereby killing rapidly dividing cancer cells. Targeted therapies, like cetuximab and bevacizumab, focus on specific molecules involved in cancer growth and spread, such as the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF). Immune checkpoint inhibitors, such as dostarlimab (a PD-1 inhibitor), enhance the body's immune response against cancer cells by blocking the PD-1 pathway, which tumors use to evade immune detection. These treatments are crucial for colorectal cancer patients as they offer multiple mechanisms to attack the cancer, potentially improving outcomes and providing options when the cancer becomes resistant to one form of therapy.
