Zepzelca® (lurbinectedin) in combination with atezolizumab approved as first-line maintenance therapy for extensive-stage small cell lung cancer in Qatar

Stockholm, Sweden, August 3, 2026 – Immedica announces that the Ministry of Public Health in the State of Qatar has granted approval for Zepzelca® (lurbinectedin) in combination with atezolizumab (Tecentriq®) as a maintenance treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) whose disease has not progressed after first-line induction therapy with atezolizumab, carboplatin and etoposide.

“The approval in Qatar marks an important milestone for people living with extensive-stage small cell lung cancer in the region. Expanding access to new treatment options is critical in a disease where time matters, and we remain committed to improving the day-to-day lives of patients and their families across the Middle East”, said Ashraf Attia, General Manager for the MENA region.

The approval is based on results from the Phase 3 IMforte trial, which showed that the lurbinectedin and atezolizumab combination reduced the risk of disease progression or death by 46% and the risk of death by 27%, compared to atezolizumab maintenance therapy alone. Following four cycles of induction therapy, from the point of randomization the median overall survival (OS) for the combination regimen was 13.2 months versus 10.6 months (stratified hazard ratio [HR]=0.73; 95% CI: 0.57–0.95; p=0.0174). From the point of randomization, median progression-free survival (PFS) by independent assessment was 5.4 months versus 2.1 months, respectively (stratified HR=0.54, 95% CI: 0.43–0.67; p<0.0001). Safety was consistent with the known safety profiles of both treatments. The results were presented at the 2025 American Society of Clinical Oncology (ASCO) annual meeting and simultaneously published in The Lancet.

Immedica has a strategic partnership with PharmaMar, where Immedica holds the distribution rights to Zepzelca in the Nordics, the UK & Ireland, Central Eastern Europe as well as in the Middle East and North Africa.

About Zepzelca® (lurbinectedin)
Zepzelca^® (lurbinectedin), also known as PM1183, is an analog of the marine compound ET-736 isolated from the sea squirt Ecteinascidia turbinata in which a hydrogen atom has been replaced by a methoxy group. It is a selective inhibitor of the oncogenic transcription programs on which many tumors are particularly dependent. Together with its effect on cancer cells, lurbinectedin inhibits oncogenic transcription in tumor-associated macrophages, downregulating the production of cytokines that are essential for the growth of the tumor. Transcriptional addiction is an acknowledged target in those diseases, many of them lacking other actionable targets.

On December 07, 2025, the Ministry of Health in the Sultanate of Oman and on June 25, 2026, the Ministry of Public Health in the State of Qatar approved Zepzelca in combination with atezolizumab or atezolizumab and hyaluronidase-tqjs, for the maintenance treatment of adult patients with ES-SCLC whose disease has not progressed after first-line induction therapy with atezolizumab or atezolizumab and hyaluronidase-tqjs, carboplatin and etoposide.

On July 13, 2023, the Ministry of Health in the Sultanate of Oman and on June 29, 2022, the Ministry of Public Health in the State of Qatar Emirates Ministry of Health & Prevention issued a Product Marketing Authorization approval for Zepzelca monotherapy for the treatment of adult patients with metastatic SCLC with disease progression on or after platinum-based chemotherapy.

About small cell lung cancer (SCLC)
SCLC is an aggressive form of lung cancer characterized by rapid growth, early metastasis, and limited therapeutic options. It accounts for about 10–15 % of all lung cancer cases and tends to present at an advanced stage, often requiring systemic therapy. Because of its aggressive nature and propensity for relapse, the prognosis remains poor.
