A Multicenter Phase II Clinical Trial of Lurbinectedin (PM01183) in Selected Advanced Solid Tumors

Multicenter, open-label, exploratory, phase II clinical trial to evaluate the efficacy and safety of PM01183 in previously treated patients with advanced solid tumors

Patients with relapsed small cell lung cancer (SCLC), head and neck carcinoma (H&N), neuroendocrine tumors (NETs), biliary tract carcinoma, endometrial carcinoma, BRCA 1/2-associated metastatic breast carcinoma, carcinoma of unknown primary site, germ cell tumors (GCTs), and Ewing's family of tumors (EFTs) will be enrolled in nine different cohorts. Up to 25 evaluable patients are planned to be enrolled in each cohort (50 in the endometrial carcinoma and 100 in the SCLC cohort).

Inclusion Criteria:

  • Biliary tract carcinoma.
  • Endometrial carcinoma.
  • BRCA 1/2- associated metastatic breast carcinoma
  • Carcinoma of unknown primary site.
  • Germ cell tumor (GCTs), excluding immature teratoma, or teratoma with malignant transformation.
  • Ewing's family of tumors (EFTs)

• Prior treatment. Patients must have received:

  • SCLC, endometrial carcinoma: one prior chemotherapy-containing line.
  • H&N, NETs, biliary tract, CUP: one or two prior chemotherapy-containing lines
  • GCTs: no limit of prior therapy
  • EFTs: no more than two prior chemotherapy-containing lines in the metastatic/recurrent setting.
  • BRCA 1/2-associated metastatic breast carcinoma: at least one but no more than three prior chemotherapy-containing lines.

• Performance status ≤ 2 [Eastern Cooperative Oncology Group (ECOG)]
