The Efficacy and Safety of Narlumosbart in Combination With Stereotactic Body Radiation Therapy to Improve the Efficacy of First-line Chemotherapy Combined With Immunotherapy in Patients With Bone Metastases From Advanced Non-small Cell Lung Cancer

ClinConnect Summary

This clinical trial is studying a new treatment approach for patients with advanced non-small cell lung cancer (NSCLC) that has spread to the bones. The researchers want to see if using a drug called narlumosbart, which targets a specific protein (RANKL), along with a focused type of radiation therapy called Stereotactic Body Radiation Therapy (SBRT), can improve the effectiveness of the standard first-line treatment that combines chemotherapy and immunotherapy. The goal is to help patients whose cancer has not responded well in the past due to the challenges posed by the bone metastases.

To participate in this trial, individuals must be between 18 and 80 years old and have confirmed stage IV NSCLC with bone metastases. Importantly, they should not have received any previous systemic treatments for their cancer. Participants will receive narlumosbart as an injection every four weeks, alongside SBRT and standard chemotherapy with immunotherapy. This study aims to measure how well this treatment works and monitor any potential side effects. If you're considering participation or want to learn more about this trial, please discuss it with your healthcare provider to see if it's a good fit for you.

Eligibility criteria

• Inclusion Criteria:
• • Signed written informed consent prior to the implementation of any trial-related procedures;
• • Age ≥ 18 years old and ≤ 80 years old;
• • Histologically or cytologically confirmed stage IV NSCLC (International Association for the Study of Lung Cancer and American Joint Committee on Cancer Classification 9th Edition TNM Lung Cancer Staging);
• • Histologically confirmed bone metastasis, which is assessed by the investigator to require local radiotherapy treatment;
• • Patients who have not undergone systemic drug therapy for lung cancer (including chemotherapy, targeting, immunotherapy, etc.);
• • Adenocarcinoma patients have been confirmed by tumour histology or cytology or haematology that the driver genes (EGFR, ALK, ROS-1) are all negative, and genetic testing is not required for squamous cell carcinoma patients;
• • At least 1 evaluable lesion other than bone metastases (refer to RECIST1.1), and lymph nodes can be used as independent measurable lesions;
• • Bone metastases other than the lesions to be radiotherapy do not require local treatment (surgery or radiotherapy) intervention after evaluation;
• • ECOG score 0-1 points;
• • Expected survival time \> 3 months;
• • Adequate organ function, subjects need to meet the following laboratory indicators: 1) In the absence of granulocyte colony-stimulating factor in the past 14 days, the absolute neutrophil value (ANC) ≥ 1.5x109/L; 2) In the case of no blood transfusion in the past 14 days, platelet ≥ 100×109/L; 3) In the absence of blood transfusion or erythropoietin in the past 14 days, haemoglobin \> 9g/dL; 4) Total bilirubin ≤ 1.5 times the upper limit of normal (ULN); 5) aspartate aminotransferase (AST) and alanine aminotransferase (ALT) at 2.5 times ULN ≤ (subjects with liver metastases are allowed ALT or AST ≤5×ULN); 6) serum creatinine ≤ 1.5 times ULN and creatinine clearance (calculated by Cockcroft-Gault formula) ≥ 60 ml/min; 7) good coagulation function, defined as international normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 times ULN; 8) Normal thyroid function, defined as thyroid-stimulating hormone (TSH) within normal limits. If the baseline TSH is outside the normal range, subjects with total T3 (or FT3) and FT4 within the normal range can also be enrolled; 9) Cardiac enzyme spectrum within the normal range (if the investigator comprehensively judges that it is not clinically significant, simple laboratory abnormalities are also allowed to enroll); For female subjects of childbearing age, a urine or serum pregnancy test with a negative result should be received within 3 days prior to receiving the first dose of study drug (Cycle 1 Day 1). If the urine pregnancy test cannot be confirmed to be negative, a blood pregnancy test is required. Females of non-childbearing potential are defined as at least 1 year postmenopausal, or have undergone surgical sterilisation or hysterectomy; If there is a risk of conception, all participants, male or female, are required to use contraception with an annual failure rate of less than 1% throughout the treatment period until 120 days after the last dose of study drug (or 180 days after the last dose of study drug).
• Exclusion Criteria:
• • The pathology is small cell lung cancer (SCLC), including lung cancer mixed with SCLC and NSCLC;
• • The lesion is an isolated lesion and can be treated radically;
• • Patients who need surgical treatment after the evaluation of the study are not allowed to enroll;
• • The radiotherapy lesion to be treated has been treated with radiotherapy or the lesion to be treated cannot be treated with radiotherapy after evaluation;
• • Presence of active brain metastases;
• • Diagnosis of other malignant diseases other than NSCLC within 5 years before the first dose (excluding radically cured basal cell carcinoma of the skin, squamous epithelial carcinoma of the skin, and/or carcinoma in situ after radical resection);

Replacement therapies (e.g., thyroxine, insulin, or physiologic glucocorticoids for adrenal or pituitary insufficiency) are not considered systemic therapy;
