Jazz Pharmaceuticals Announces U.S. FDA Accelerated Approval of Zepzelca™ (lurbinectedin) for the Treatment of Metastatic Small Cell Lung Cancer

"Small cell lung cancer is a disease with limited treatment options, and the approval of Zepzelca represents an important advance for patients whose metastatic SCLC has progressed on or after platinum-based therapy," said

About Zepzelca™ (lurbinectedin)
Zepzelca, also known as PM1183, is an alkylating drug that binds guanine residues within DNA. This triggers a cascade of events that can affect the activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in disruption of the cell cycle and eventual cell death.1
Zepzelca for injection 4 mg is a prescription medicine used to treat adults with a kind of lung cancer called small cell lung cancer (SCLC) that has spread to other parts of the body (metastatic) and who have received treatment with chemotherapy that contains platinum, and it did not work or is no longer working. Zepzelca is approved based on response rate and how long the response lasted. Additional studies will further evaluate the benefit of Zepzelca for this use.
