ZEPZELCA

LURBINECTEDIN Alkylating Activity
Oncology Approved 2020-06-15

ZEPZELCA (lurbinectedin) is an alkylating drug indicated for the treatment of adult patients with small cell lung cancer (SCLC). It is indicated as maintenance therapy in combination with atezolizumab (or atezolizumab and hyaluronidase-tqjs) for patients with extensive-stage SCLC (ES-SCLC) whose disease has not progressed following first-line induction therapy with an atezolizumab-containing regimen, carboplatin, and etoposide. Additionally, ZEPZELCA is indicated as a monotherapy for adult patients with metastatic SCLC who have experienced disease progression during or after platinum-based chemotherapy. This second indication was granted under accelerated approval based on overall response rate and duration of response; continued approval may be contingent upon verification of clinical benefit in confirmatory trials.

How ZEPZELCA Works

Lurbinectedin is an alkylating drug that binds to guanine residues within the minor groove of DNA, forming adducts that bend the DNA helix toward the major groove. This structural deformation triggers a cascade of events that interferes with the activity of DNA-binding proteins, including specific transcription factors and DNA repair pathways, resulting in cell cycle perturbation and eventual apoptosis. Beyond its direct cytotoxic effects, lurbinectedin has been shown to inhibit human monocyte activity and reduce macrophage infiltration in tumor microenvironments.
