Patients and methods This phase II trial evaluated lurbinectedin, a selective inhibitor of oncogenic transcription, at 3.2 mg/m2 as a 1-h intravenous infusion every 3 weeks in 32 NETs patients treated in the second- or third-line setting. The primary efficacy endpoint was overall response rate (ORR) according to RECIST v1.1 assessed by the investigators. Secondary endpoints included duration of response (DoR), progression-free survival (PFS), overall survival (OS) and safety. Results Two of 31 evaluable patients had confirmed partial responses (ORR = 6.5%; 95%CI, 0.8–21.4%). Median DoR was 4.7 months (95% CI, 4.0–5.4 months), median PFS was 1.4 months (95% CI, 1.2–3.0 months) and median OS was 7.4 months (95% CI, 3.4–16.2 months). Lurbinectedin showed an acceptable, predictable and manageable safety profile. The most common grade 3/4 toxicity was neutropenia (40.6%; grade 4, 12.4%; febrile neutropenia, 3.1%). Conclusions Considering the exploratory aim of this trial that evaluated a heterogeneous population of NETs patients, and the signs of antitumour activity observed (two confirmed partial responses and seven long disease stabilisations), further development of lurbinectedin is warranted in a more selected NETs population. http://hdl.handle.net/11351/8198 Tumors neuroendocrins - Tractament Teràpia intravenosa Avaluació de resultats (Assistència sanitària) DISEASES::Neoplasms::Neoplasms by Histologic Type::Neoplasms, Germ Cell and Embryonal::Neuroectodermal Tumors::Neuroendocrine Tumors Other subheadings::Other subheadings::Other subheadings::/drug therapy ANALYTICAL, DIAGNOSTIC AND THERAPEUTIC TECHNIQUES, AND EQUIPMENT::Therapeutics::Drug Therapy::Drug Administration Routes::Administration, Intravenous::Infusions, Intravenous ANALYTICAL, DIAGNOSTIC AND THERAPEUTIC TECHNIQUES, AND EQUIPMENT::Diagnosis::Prognosis::Treatment Outcome ENFERMEDADES::neoplasias::neoplasias por tipo histológico::neoplasias de células germinales y embrionarias::tumores neuroectodérmicos::tumores neuroendocrinos Otros calificadores::Otros calificadores::Otros calificadores::/farmacoterapia TÉCNICAS Y EQUIPOS ANALÍTICOS, DIAGNÓSTICOS Y TERAPÉUTICOS::terapéutica::farmacoterapia::vías de administración de medicamentos::administración intravenosa::infusiones intravenosas TÉCNICAS Y EQUIPOS ANALÍTICOS, DIAGNÓSTICOS Y TERAPÉUTICOS::diagnóstico::pronóstico::resultado del tratamiento Lurbinectedin in patients with pretreated neuroendocrine tumours: Results from a phase II basket study
