Opdivo: Un medicament versatil care combate mai multe tipuri de cancer

What Is Opdivo?

Opdivo is a brand name for the medication nivolumab, which is a type of immunotherapy drug used to treat certain types of cancer. Opdivo was first approved by the FDA in 2014 to treat advanced melanoma that is unresponsive to other types of treatments. Since then, Opdivo has been approved for several other types of cancer due to its successful clinical trial data supporting its safety and effectiveness in treating various cancer types.

This immunotherapy medication belongs to the anti-programmed cell death-1 (PD-1) drug class, which mainly targets and blocks the activity of specific proteins that suppress the immune system.

Opdivo is only available by prescription and comes in a single-dose vial solution for injection. 

What Is Opdivo Used To Treat?

Since the first approval of Opdivo until now, the FDA has approved the use of Opdivo in the treatment of several types of cancer, which include:

• Melanoma (advanced skin cancer)
• Metastatic non-small cell lung cancer
• Squamous cell carcinoma of the head and neck
• Classical Hodgkin’s lymphoma (cancer of lymphocytes)
• Hepatocellular carcinoma (liver cancer)
• Urothelial carcinoma (cancer of the bladder and urinary tract)
• Advanced renal cell carcinoma (cancer of the kidney)
• Colorectal cancer (bowel cancer)
• Esophageal cancer (cancer that develops in the esophagus)
• Malignant pleural mesothelioma (cancer of the lung’s lining)
• Gastric cancer (stomach cancer)
• Gastroesophageal junction cancer (cancer that occurs where the esophagus meets the stomach)
• Esophageal adenocarcinoma (cancer that begins in the glandular cells of the esophagus)

Opdivo is commonly used to treat advanced or metastatic cancer that has invaded other body parts and is resistant to treatment with conventional therapies. It is often used alone or combined with other cancer treatments, such as immunotherapy drugs, chemotherapy, and radiation therapy. 

How Does Opdivo Work?

Opdivo contains an active drug called nivolumab, a monoclonal antibody that works by helping the body’s immune system fight cancer cells. Normally, our immune system has specialized cells, specifically T-cells, that can detect and kill cancer cells. However, some cancer cells produce certain proteins called PD-L1 and PD-L2 to avoid T-cell detection. These proteins (PD-L1 and PD-L2) attach to a receptor on T-cells called PD-1 and shut down the T-cell’s activity, consequently preventing T-cells from attacking cancer cells and allowing them to grow and spread.

Opdivo is designed to bind to the PD-1 receptor on T-cells. When Opdivo attaches to the PD-1 receptor, it prevents the cancer cell proteins (PD-L1 and PD-L2) from binding to the T-cells and turning them off. This allows the T-cells to remain active and recognize and destroy cancerous cells.

By blocking the binding of PD-L1 and PD-L2 proteins, Opdivo boosts the immune system’s ability to identify and kill cancer cells, slowing down or stopping the growth of the tumor.

The intravenous dose of Opdivo is 240 mg once every 2 weeks or 480 mg once every 4 weeks, which is infused over 30 minutes in adult patients with melanoma, metastatic non-small cell lung cancer, advanced renal cell carcinoma, classical Hodgkin lymphoma, squamous cell carcinoma of the head and neck, locally advanced or metastatic urothelial carcinoma, esophageal squamous cell carcinoma, and colorectal cancer. 

• For pediatric patients with colorectal cancer (weighing 40 kg or more), Opdivo is given intravenously every 4 weeks at a recommended dose of 240 mg over 30 minutes.
• For pediatric patients (12 years or older) with colorectal cancer and weighing less than 40 kg, the dose of Opdivo as a single agent is 3 mg/kg once every 2 weeks, over 30 minutes.

The treatment continues until the disease progresses or until unacceptable side effects occur. If there is no disease progression, treatment can continue for up to 2 years.
