PharmaMar and Jazz Pharmaceuticals Announce Initiation of Confirmatory Phase 3 Clinical Trial of Zepzelca® (lurbinectedin) for the Treatment of Patients with Relapsed Small Cell Lung Cancer
MADRID and DUBLIN, Dec. 13, 2021 /PRNewswire/ -- PharmaMar (MSE: PHM) and partner Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced the initiation of a confirmatory Phase 3 clinical trial, LAGOON, evaluating Zepzelca® (lurbinectedin) for the treatment of patients with relapsed small cell lung cancer (SCLC). The trial will measure overall survival (OS) as the primary endpoint and progression-free survival (PFS) as a secondary endpoint of lurbinectedin monotherapy or lurbinectedin in combination with irinotecan compared with investigator's choice of topotecan or irinotecan, in patients with SCLC whose disease has progressed following prior platinum-containing chemotherapy with or without anti-PD-1 or anti-PD-L1 agents.
"We are very excited about this trial, which is designed to reinforce lurbinectedin as a second-line treatment of choice in the U.S. and has the potential to bring our treatment to European patients," said Ali Zeaiter, director of clinical development, PharmaMar Oncology Business Unit.
"There has been strong clinical demand for Zepzelca following the FDA's accelerated approval, which demonstrates that this important therapy is filling a significant unmet need for the metastatic small cell lung cancer community," said Rob Iannone, M.D., M.S.C.E., executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals. "We are committed to working with PharmaMar and the FDA to further demonstrate the clinical benefit of Zepzelca and support conversion to full regulatory approval in the U.S."
LAGOON is a Phase 3, randomized (1:1:1), multicenter, open-label clinical trial with three arms: one arm to receive lurbinectedin 3.2 mg/m2 as monotherapy (the approved dose in the U.S.), the second arm to receive lurbinectedin 2.0 mg/m2 in combination with irinotecan 75 mg/m2, and the third arm to receive topotecan or irinotecan based on the investigators' choice. The trial will be conducted in patients with SCLC, whose disease has progressed following prior platinum-containing chemotherapy with or without anti-PD-1 or anti-PD-L1 agents. LAGOON is expected to enroll 705 patients from more than 100 sites mainly in North America and Europe.
The FDA approved Zepzelca under accelerated approval in June 2020 for the treatment of adult patients with metastatic SCLC with disease progression on or after platinum-based chemotherapy. The approval is based on overall response rate (ORR) and duration of response demonstrated in an open-label, monotherapy clinical study. If successful, LAGOON will serve as the confirmatory trial for Zepzelca to secure full approval in the U.S. LAGOON will also be used as a registrational trial with the European Medicines Agency (EMA) to obtain marketing authorization in Europe. Jazz Pharmaceuticals holds the commercial rights for Zepzelca in North America.
In 2021, lurbinectedin received marketing authorization in the United Arab Emirates, Canada, Australia and Singapore. Additional marketing authorizations are expected in 2022 and beyond.
About Zepzelca® (lurbinectedin)
Zepzelca 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.i
Zepzelca is a prescription medicine used to treat adults with small cell lung cancer 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. Zepzelca is not approved as part of a combination therapy or as a first-line maintenance treatment for patients with extensive-stage small cell lung cancer.
Important Safety Information for Patients

Some people with low white blood cell counts may get fever, or an infection throughout the body (sepsis), that can cause death. Your healthcare provider should do blood tests before you receive each treatment with ZEPZELCA to check your blood cell counts.
Tell your healthcare provider right away if you develop:
- fever or any other signs of infection
- unusual bruising or bleeding
- pale colored skin
- Liver problems. Increased liver function tests are common with ZEPZELCA, and can also be severe. Your healthcare provider should do blood tests to check your liver function before you start and during treatment with ZEPZELCA.
Tell your healthcare provider right away if you develop symptoms of liver problems including:
- loss of appetite
- nausea or vomiting
- pain on the right side of your stomach area (abdomen)
Your healthcare provider may temporarily stop treatment, lower your dose, or permanently stop ZEPZELCA if you develop low blood cell counts or liver problems during treatment with ZEPZELCA.
The most common side effects of ZEPZELCA include:
- low white and red blood cell counts
- increased kidney function blood test (creatinine)
- increased liver function blood tests
- increased blood sugar (glucose)
- decreased appetite
- muscle and joint (musculoskeletal) pain
