Lurbinectedin, sold under the brand name Zepzelca, is a medication used to treat small cell lung cancer (SCLC).[1] It is used when the disease has spread despite other treatments.[1] It is given by gradual injection into a vein.[1]

Common side effects include low white blood cells, low red blood cells, kidney problems, low platelets, nausea, muscle pain, shortness of breath, liver inflammation, and constipation.[1] Other side effects may include infertility.[1] Use in pregnancy may harm the baby.[1] It is an alkylating agent.[1] It works by interfering with DNA duplication required for cell division.[3]

Lurbinectedin was approved for medical use in the United States in 2020 and Australia in 2021.[4][2] In the United States 4 mg costs about 7,200 USD as of 2021.[5] As of 2021 it is not available in the United Kingdom or Europe.[6]

Medical uses

Dosage

It is generally give at a dose of 3.2 mg/m2 every 3 weeks.[1]

Mechanism of action

Lurbinectedin inhibits the active transcription of the encoding genes. This has two consequences. It promotes tumor cell death and normalizes the tumor microenvironment. Active transcription is the process by which there are specific signal where information contained in the DNA sequence is transferred to an RNA molecule. This activity depends on the activity of an enzyme called RNA polymerase II. Lurbinectedin inhibits transcription through a very precise mechanism. Firstly, lurbinectedin binds to specific DNA sequences. It is at these precise spots that slides down the DNA to produce RNA polymerase II that is blocked and degraded by lurbinectedin. Lurbinectedin also has important role in tumor microenvironment. The tumor cells act upon macrophages to avoid them from behaving like an activator of the immune system. Literally, macrophages work in any tumor's favor. Macrophages can contribute to tumor growth and progression by promoting tumor cell proliferation and invasion, fostering tumor angiogenesis and suppressing antitumor immune cells.[7][8] Attracted to oxygen-starved (hypoxic) and necrotic tumor cells they promote chronic inflammation. So, not only that macrophages inhibit immune system avoiding the destruction of tumor cells, but they also create tumor tissue that allows tumor growth. However, macrophages associated with tumors are cells that are addicted to the transcription process. Lurbinectedin acts specifically on the macrophages associated with tumors in two ways: firstly, by inhibiting the transcription of macrophages that leads to cell death and secondly, inhibiting the production of tumor growth factors. In this way, lurbinectedin normalizes the tumor microenvironment.

Chemistry

Lurbinectedin is structurally similar to trabectedin, although the tetrahydroisoquinoline present in trabectedin is replaced with a tetrahydro β-carboline which enables lurbinectedin to exhibit increased antitumor activity compared with trabectedin.[9]

Biosynthesis

Lurbinectedin a marine agent isolated from the sea squirt species Ecteinascidia turbinata. Synthetic production is necessary because very small amounts can be obtained from sea organisms. For example, one ton (1000 kg) of sea squirts are required to produce one gram of trabectedin, which is analogue of lurbinectedin. Complex synthesis of lurbinectedin starts from small, common starting materials that require twenty-six individual steps to produce the drug with overall yield of 1.6%.[10][11]

History

Lurbinectedin was approved for medical use in the United States in June 2020.[12][1][13][14]

Efficacy was demonstrated in the PM1183-B-005-14 trial (Study B-005; NCT02454972), a multicenter open-label, multi-cohort study enrolling 105 participants with metastatic SCLC who had disease progression on or after platinum-based chemotherapy.[13][14] Participants received lurbinectedin 3.2 mg/m2 by intravenous infusion every 21 days until disease progression or unacceptable toxicity.[13] The trial was conducted at 26 sites in the United States, Great Britain, Belgium, France, Italy, Spain and Czech Republic.[14]

The U.S. Food and Drug Administration (FDA) granted the application for lurbinectedin priority review and orphan drug designations and granted the approval of Zepzelca to Pharma Mar S.A.[13][15]

Research

Lurbinectedin can be used as monotherapy in the treatment of SCLC.[medical citation needed] Lurbinectedin monotherapy demonstrated the following clinical results in relapsed extensive stage SCLC:

  • For sensitive disease (chemotherapy-free interval of ≥ 90 days) overall response rate (ORR) was 46.6% with 79.3% disease control rate and median overall survival (OS) being increased to 15.2 months.[16]
  • For resistant disease (chemotherapy-free interval of < 90 days) overall response rate (ORR) was 21.3% with 46.8% disease control rate and 5.1 months median overall survival (OS).[16]

Lurbinectedin is also being investigated in combination with doxorubicin as second-line therapy in a randomized Phase III trial.[medical citation needed] While overall survival in this trial is not yet known, response rates at second line were

  • 91.7% in sensitive disease with median progression-free survival of 5.8 months, and
  • 33.3% in resistant disease with median progression-free of 3.5 months.[17]

Lurbinectedin is available in the U.S. under Expanded Access Program (EAP).[17][18]
