Multicenter, open label, single arm, phase II study to assess the efficay and safety of enfortumab-vedotin (EV) as a single agent in patients with advanced Neuroendocrine Carcinomas (NEC).
EU CTIS ID: 2024-515511-21-00
What this study is testing
To assess efficacy in terms of the objective radiological response rate of single-agent EV in patients with locally advanced or metastatic NEC, of any origin except lung, or NET-G3 with a Ki-67 index > 20% of any origin, excluding lung that are refractory to or ineligible for first-line platinum-based chemotherapy.
- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Patients 18 years of age or older.
- Women who are not surgically sterile or post-menopausal (for at least one year) and men who have not had a vasectomy must use highly effective contraception measures. (Please see section 13.3.8 of protocol for further details).
- Patients who give informed consent to participate in the study.
- Patients with histologically documented poorly-differentiated neuroendocrine carcinoma of any origin, excluding the lung, or histologically documented well-differentiated neuroendocrine tumours of grade 3 histology with a Ki-67 index >20%, of any origin, excluding the lung, who have failed at least one prior line of platinum-based systemic therapy or are considered ineligible for platinum-based chemotherapy
- Patients with radiologically documented metastatic or locally advanced disease at the start of the study. Subjects with brain metastases must have clinically controlled neurological symptoms and must have completed radiotherapy at least 21 days prior to administration of the first dose of study drug.
- Patients with ECOG score 0-2.
You likely can't join if
- Prior systemic treatment with any antimicrotubule agent such as taxanes or Enfortumab Vedotin, or more than two lines of chemotherapy-based systemic therapy, excluding adjuvant or neoadjuvant treatments.
- Patients with known hypersensitivity to EV or any excipient contained in the EV pharmaceutical formulation (including histidine, trehalose dihydrate, and polysorbate 20).
- Patients with poorly controlled diabetes (glycated haemoglobin ≥ 10%).
- Grade 2 or higher peripheral neuropathy.
- Patients with evidence of other severe uncontrolled disease as judged by the investigator.
- Patients with active immune thrombocytopenic purpura, autoimmune haemolytic anaemia, or a history of being refractory to platelet transfusions (within 1 year prior to the 1st dose of study drug).
