Atezolizumab

Introduction

Atezolizumab is a monoclonal antibody-based immunotherapy used to treat various forms of cancer, including lung, bladder, and breast cancers. It belongs to a class of drugs called immune checkpoint inhibitors that help the immune system recognize and attack cancer cells more effectively. Administered under the supervision of a healthcare provider, Atezolizumab has shown promising results in prolonging survival and improving the quality of life in cancer patients. It is typically given as an intravenous infusion and is often used when other treatments have not been effective or as part of combination therapy.

Uses of Atezolizumab

• Non-small cell lung cancer (NSCLC)
• Triple-negative breast cancer (TNBC)
• Urothelial carcinoma (bladder cancer)
• Hepatocellular carcinoma (liver cancer)
• Small cell lung cancer (SCLC)

How Atezolizumab Works

Atezolizumab blocks the PD-L1 protein found on cancer cells. This protein normally suppresses immune responses. By inhibiting PD-L1, Atezolizumab helps activate T-cells, allowing them to detect and destroy cancer cells more effectively. This enhances the body’s natural immune response against tumors.

Benefits of Atezolizumab

• Improves survival rate in advanced cancers
• Enhances immune system function against tumors
• Can be used in combination with other therapies
• Effective even in some chemotherapy-resistant cases
• Generally well-tolerated compared to traditional chemotherapy

Atezolizumab is administered as an intravenous (IV) infusion by a healthcare professional, usually in a hospital or clinic. The dosage and frequency depend on the type of cancer being treated, patient weight, and medical condition. It is typically given once every 2 to 4 weeks. Do not self-administer this medication. Regular monitoring of blood tests and organ functions is required during treatment.
