Tislelizumab in Combination With GP or TPC Regimen for the Treatment of Nasopharyngeal Carcinoma With Bone Metastasis.

A Randomized, Controlled, Multicenter Clinical Study Comparing the Efficacy of Pembrolizumab in Combination With Nab-TPC Regimen Versus the GP Regimen in the First-Line Treatment of Nasopharyngeal Carcinoma With Bone Metastases.

This is a prospective, open-label phase III clinical trial evaluating the efficacy and safety of the GP（Gemcitabine combined with cisplatin） regimen in combination with Tislelizumab versus the TPC（cisplatin, nab-paclitaxel and capecitabine）regimen in combination with Tislelizumab for the first-line treatment of Nasopharyngeal Carcinoma patients With Bone Metastasis.

Description

Inclusion Criteria:

1. Age≥ 18 years.
2. Histology or cytology confirmed nasopharyngeal carcinoma.
3. Metastatic nasopharyngeal carcinoma of bone that is not suitable for local or radical therapy.
4. Distant bone metastases confirmed by imaging (two images) or pathology (plus one image) (AJCC 8th, stage IVB), except for isolated local invasion of the base bone of the skull.

6. Bone metastases may contain soft tissue components of osteolytic lesions.
7. Patients have not previously received systemic therapy for advanced or metastatic disease, and prior induction chemotherapy, concurrent chemoradiotherapy, or adjuvant chemotherapy must have been completed more than 6 months prior to enrollment. Previous radiotherapy or concurrent chemoradiotherapy should also be completed more than 6 months prior to enrollment.
8. Expected survival ≥ 3 months.
9. According to the Eastern Cooperative Oncology Group (ECOG) criteria, the performance status score is 0 or 1.

Exclusion Criteria:

1. Patients with osteo-oligometastatic nasopharyngeal carcinoma.
2. Previous history of severe hypersensitivity to any component of other monoclonal antibodies or tislelizumab monoclonal mab.

4. No definitive surgical and/or radiotherapy for spinal cord compression, or for previously diagnosed and treated spinal cord compression, no evidence that the disease was clinically stable for ≥ 2 weeks prior to enrollment.
5. Poorly controlled pleural effusion, pericardial effusion, or ascites requiring frequent drainage. Patients with indwelling catheters, such as PleurX ® catheters, are allowed to participate.
6. Poorly controlled tumor-related pain. Patients requiring analgesic therapy must receive a stable dose before enrolling in the study. Patients who are candidates for palliative radiation therapy (e.g., bone metastases or metastases leading to nerve damage) should be treated prior to enrollment Lesions are treated. Prior to enrollment, if appropriate, consideration should be given to the need for further growth that may result in functional deficits or intractable pain (e.g., For example, asymptomatic metastases currently not associated with spinal cord compression) are treated locally-regionally.
7. Poorly controlled or symptomatic hypercalcemia (> 1.5 mmol/L ionized calcium or calcium> 12 mg/dL or corrected serum calcium higher than ULN)
