DAREON®-36: A Study to Test Obrixtamig in Combination With ZL-1310 in People With Advanced Small Cell Lung Cancer or Other Neuroendocrine Cancers

31 augustus 2026 bijgewerkt door: Boehringer Ingelheim

A Phase Ib/II, Open-label, Safety and Tolerability Trial of Obrixtamig in Combination With ZL-1310 in Patients With Poorly Differentiated NEC

This study is open to adults with advanced small cell lung cancer and other neuroendocrine cancers. The study has 2 parts. The purpose of Part 1 is to find a suitable dose of a combination study treatment, obrixtamig and ZL-1310. The purpose of Part 2 is to see how obrixtamig and ZL-1310 is tolerated when given with another medicine called a checkpoint inhibitor. Another purpose is to check whether the study treatment can stop the cancer from growing and keep it stable. Obrixtamig and ZL-1310 are being developed to help the immune system fight cancer.

In Part 1, participants get obrixtamig and ZL-1310. In Part 2, participants get obrixtamig and ZL-1310 with a checkpoint inhibitor. Part 2 is only open to people with advanced small cell lung cancer. All study treatments are given as infusions into a vein.

The study does not have a fixed duration. Participants can receive study treatment for up to 2 years if they benefit from treatment and can tolerate it. Participants visit the study site regularly, with some overnight stays required. During this time, doctors regularly check for health problems that could be caused by the study treatment. They also monitor the size of the tumour(s) and take laboratory tests.

    • Small cell lung carcinoma (SCLC)
    • Large cell neuroendocrine lung carcinoma (LCNEC-L)
    • Extrapulmonary neuroendocrine carcinoma (epNEC) of small or large cell histology
  2. Patients with tumours with mixed histologies for any above type are eligible only if the neuroendocrine carcinoma/small cell component is predominant and represents at least 50% of the overall tumour tissue

  3. Patients for whom no therapy of proven efficacy exists or who are not eligible for established treatment options. Patients must have exhausted available treatment options known to prolong survival for their disease. Previous therapies should include at least one line of platinum-based chemotherapy, unless there is a documented medical reason not to use platinum

    For Part 2

  3. Presence of leptomeningeal disease and/or carcinomatous meningitis
  4. Known hypersensitivity to the trial drugs or their excipients, prior severe, life-threatening hypersensitivity reaction(s) to monoclonal antibodies, or significant risk of allergic or anaphylactic reaction(s) to any of the investigated drug products according to the investigator's judgement
  5. Participants who experienced severe, life-threatening immune-mediated adverse events, e.g. serious Grade 3 or higher immune-related adverse event (imAE) or infusion-related reactions, that led to permanent discontinuation while on treatment with immuno-oncology agents
  6. Persistent toxicity from previous treatments that has not resolved to ≤ Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 (except for alopecia, asthenia/fatigue, amenorrhea/menstrual disorders, CTCAE Grade 2 peripheral neuropathy, and CTCAE Grade 2 endocrinopathies controlled by replacement therapy, and toxicities, which are considered irreversible but stable for at least 4 weeks, per investigator judgment)
