To Evaluate the Efficacy and Safety of QL1206 and Xgeva in Patients With Bone Metastases From Solid Tumors

Study Overview
=================
Brief Summary
-----------------
A multi-center, randomized, double-blind, comparative study to evaluate the clinical efficacy and safety of QL1206 and Xgeva® in patients with bone metastases from solid tumors.

Detailed Description
-----------------
This is A multi-center, randomized, double-blind, comparative clinical trial. The primary objective is to evaluate whether the clinical efficacy of QL1206 and Xgeva® are similar in patients with bone metastases from solid tumors. The secondary objective are to evaluate whether the clinical safety and immunogenicity of QL1206 and Xgeva® are similar in patients with bone metastases from solid tumors.

Eligibility Criteria
-----------------
Inclusion Criteria: Through the explanation of the researcher or the researcher's authorized representative, the subject has understood the nature and purpose of the study, as well as the research procedure, and the subject has signed the written informed consent; Radiologic evidence (i.e. X-ray examination, computed tomography CT, magnetic resonance imaging MRI, positron emission computed tomography PET-CT) in grade III grade A hospitals has been documented (within 3 months prior to study administration) that there is at least one bone metastasis; The ECOG score was 0-2. Chinese adults with solid tumor confirmed by histological or cytological examination (age ≥18 years, ≤80 years). Exclusion Criteria: Patients who had received any kind of intravenous or oral bisphosphonates before administration of the first study drug (those who had previously used an intravenous or oral bisphosphonates but had a continuous use time of less than 3 months and more than 5 years before the administration of this study could be included in the study). Previous treatment with denosumab. Previous or ongoing osteomyelitis or osteonecrosis of the jaw ONJ , active dental disease or jaw bone disease requiring oral surgery, the wound of dental operation or oral surgery has not healed well, or invasive dental operation has been planned during the study period. Plan to perform radiotherapy or or bone surgery. Patients who received radiotherapy within one month before the first study drug administration were not allowed to be included.
