## TL;DR

A marine-derived chemotherapy that jams cancer's gene-reading machinery, approved for relapsed small-cell lung cancer and, since 2025, as first-line maintenance with atezolizumab.

## Summary

Accelerated approval June 2020 for metastatic SCLC after platinum (ORR 35%, DOR 5.3 months, basket phase 2). ATLANTIS (with doxorubicin) missed OS; IMforte (with atezolizumab as first-line maintenance) improved OS and PFS, leading to full approval on 2 October 2025. Also studied in the LAGOON second-line trial. Jazz Pharmaceuticals (US) and PharmaMar.

## Fields

- Kind: Treatment
- Status: approved
- Last checked: 2026-09-07
- Brand: Zepzelca
- Code: PM01183
- Modality: Cytotoxic (transcription inhibitor)
- Mechanism: Binds the DNA minor groove at CG-rich promoters, stalls RNA polymerase II and triggers its degradation; also depletes tumour-associated macrophages.
- Approvals: US 2020: Metastatic SCLC after platinum chemotherapy (accelerated); US 2025: First-line maintenance with atezolizumab in ES-SCLC (full approval); EU 2026: Maintenance with atezolizumab in ES-SCLC after first-line induction; 29 May 2026
- Dosing: Intravenous; 3.2 mg/m² over 60 minutes every 21 days (monotherapy); with atezolizumab 1200 mg in maintenance
- Toxicity (grade 3+): Neutropenia 46%

## Notes

- Lurbinectedin has no United Kingdom marketing authorisation and no NICE appraisal, so it is not available on the NHS in England, although it holds FDA approval (accelerated, 15 June 2020, converted on the IMforte maintenance data) and an EU authorisation for maintenance with atezolizumab.
