What This Trial Is Studying

This study is open to adults with advanced extrapulmonary neuroendocrine cancer. The purpose of this study is to find out if a study medicine called obrixtamig plus standard chemotherapy (carboplatin and etoposide) improves survival when compared to standard chemotherapy (carboplatin and etoposide) alone. Obrixtamig is an antibody-like molecule that may help the immune system fight cancer. Another purpose of the study is to test a medical device being developed to measure levels of the tumour marker delta-like ligand 3 (DLL3). Participants are put into 2 groups randomly, which means by…

Eligibility Snapshot
  • : 1. Patients with poorly differentiated unresectable locally advanced or metastatic extrapulmonary neuroendocrine carcinoma (epNEC) with Ki-67 >20% or mitotic rate mitotic rate with number of mitoses >20 per 2 mm2, regardless of primary site (including site of unknown origin) 2. Patients with tumours with mixed histologies are eligible only if neuroendocrine carcinoma component is predominant and represents more than 70% of the overall tumour tissue 3. No prior systemic treatment for unresectable locally advanced or metastatic epNEC (except for the completed one cycle of standard platinum + etoposide). Prior peri-operative chemotherapy or -radiation for curative intention is allowed if at least 6 months have elapsed between completion of this therapy and diagnosis of unresectable locally advanced or metastatic disease 4. Patients who have finished one cycle of standard platinum + etoposide regimen as first-line treatment (Cycle 0: etoposide with carboplatin or cisplatin, administered at a minimum dose of cisplatin 75 mg/m2 or carboplatin area under the curve (AUC) 5 and etoposide 80 mg/m2) prior to randomisation 5. Patients must comply with criteria for receiving further chemotherapy treatment as first-line standard of care (SoC) treatment within 28 days after the start of the initial chemotherapy (Cycle 0) 6. Adequate…
