Lifileucel (Mechanism of Action) Lifileucel is a cell-based immunotherapy treatment used for patients with metastatic melanoma. Mechanism of Action • Tumor-Infiltrating Lymphocytes (TILs): Lifileucel is composed of autologous (patient-derived) tumor-infiltrating lymphocytes (TILs). These are immune cells that have naturally infiltrated the tumor and are capable of recognizing and attacking cancer cells. • Personalized Treatment: The […]

ALK and its Role in Cancer
ALK and Its Role in Cancer 1. ALK Gene: • Normal Function: ALK is a gene that provides instructions for making a protein involved in cell growth and division. Under normal conditions, it plays a role in the development of the nervous system. • Mutations and Fusions: When the ALK gene undergoes mutations or fuses […]
Hepatotoxicity and Ceritinib (Studies and Clinical Data) Studies and Data • ASCEND Trials: In the ASCEND clinical trials, which evaluated ceritinib’s efficacy and safety, hepatotoxicity was among the most commonly reported adverse effects. Elevations in ALT and AST were observed in a significant percentage of patients, leading to dose modifications in some cases . • […]
Hepatotoxicity and Ceritinib (4) Guidelines for Management • Mild Elevations: For mild (Grade 1 or 2) elevations in liver enzymes, close monitoring and continued treatment may be sufficient. • Moderate to Severe Elevations: For more severe elevations (Grade 3 or 4), treatment interruption and dose reduction are recommended until liver enzymes return to acceptable levels. […]
Hepatotoxicity and Ceritinib (3) Clinical Management: • Monitoring: Regular monitoring of liver function tests (LFTs) is recommended for patients on ceritinib. This typically includes tests for ALT, AST, alkaline phosphatase, and bilirubin levels. • Dose Adjustments: Depending on the severity of hepatotoxicity, dose adjustments, interruptions, or discontinuation of ceritinib may be necessary. Guidelines suggest specific […]
Hepatotoxicity and Ceritinib (2) Mechanism • Direct Hepatotoxicity: Ceritinib may cause direct liver cell damage, leading to elevated liver enzymes and bilirubin levels. The exact mechanism is not entirely understood but is thought to involve direct hepatocyte injury or immune-mediated mechanisms
