本研究对患有晚期小细胞肺癌( SCLC )的成年人开放。本研究的目的是了解一种名为obrixtamig加标准治疗(阿特珠单抗、卡铂和依托泊苷)的研究药物与单独的标准治疗相比是否能改善生存期。Obrixtamig是一种类似抗体的分子,可能有助于免疫系统对抗癌症。
适应症:Small Cell Lung Cancer (SCLC)、Extensive-stage Small Cell Lung Cancer (ES-SCLC)
入组条件
纳入标准
- Patients with histologically confirmed Extensive-stage Small Cell Lung Cancer (ES-SCLC)
- Patients without any previous systemic anti-cancer treatment for ES-SCLC. Patients who received previous systemic anti-cancer treatment during limited stage are eligible if the treatment has been completed more than 6 months before the diagnosis of ES-SCLC.
- Adequate archival formalin-fixed paraffin-embedded (FFPE) tumour tissue, as specified in the Laboratory Manual, must be available for central laboratory analysis of Delta-like ligand 3 (DLL3) expression status and other biomarkers. The central laboratory investigational VENTANA DLL3 (SP347) RxDx test result must be available prior to randomisation.
- Patients with asymptomatic brain metastasis are eligible if they meet one of the following criteria:
- Treatment for brain metastases (e.g. whole brain radiation therapy, stereotactic radiotherapy, or radiosurgery) completed at least 7 days prior to randomisation and the patient is neurologically stable without the use of glucocorticoids or therapeutic anti-convulsant for at least 7 days prior to randomisation
- Untreated brain metastases that do not require treatment and the patient is neurologically stable without the use of glucocorticoids or therapeutic anti-convulsant for at least 28 days prior to randomisation
- Eastern Cooperative Oncology Group (ECOG) score of 0 or 1
- Eligible for continuing carboplatin + etoposide + atezolizumab regimen as first-line Standard of care (SoC) treatment within 28 days after the start of the initial cycle of standard therapy
排除标准
- Presence of leptomeningeal disease and/or carcinomatous meningitis
- Previous treatment targeting DLL3 (e.g. T cell engagers (TcEs), cell therapies, antibody-drug conjugates, or radiopharmaceuticals)
- Radiotherapy of any anatomical site within 7 days prior to randomisation
- Toxicity from previous treatments that has not resolved to ≤ Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 or baseline. Patients with alopecia, any grade, CTCAE ≤Grade 2, asthenia/fatigue, amenorrhea/menstrual disorders any grade, CTCAE Grade ≤2 peripheral neuropathy, and/or CTCAE Grade 2 endocrinopathies controlled by replacement therapy, and toxicities, which are considered irreversible but stable for at least 4 weeks prior to randomisation, per investigator judgment may be eligible. Note: Patients who developed toxicity from the cycle of standard therapy received prior to randomisation are eligible if adequate organ function is ensured as described
- Patient with active autoimmune disease or a documented history of autoimmune disease that requires systemic treatment (e.g. glucocorticoids or immunosuppressive drugs). Patients with vitiligo, resolved childhood asthma/atopy, alopecia, or any chronic skin condition that does not require systemic therapy, patients with autoimmune-related hypothyroidism on a stable dose of thyroid replacement hormone and/or controlled Type 1 diabetes mellitus on a stable insulin regimen may be included if in the opinion of the investigator it is appropriate and safe to do so.
