Phase 1 |
Detailed Description
The objective of this trial is to evaluate the efficacy and safety of JMT103 in patients with bone metastases from solid tumors.
Eligible patients will be randomly assigned to receive JMT103 120mg subcutaneously (SC) every 4 weeks (Q4W), 120mg subcutaneously (SC) every 8 weeks (Q8W) and 180mg subcutaneously (SC) every 8 weeks (Q8W) in a 1:1:1 ratio. Patients will receive the treatment until the completion of 48 weeks of treatment, intolerable toxicity, loss to follow-up, withdrawal (patient's decision or investigator's decision), whichever comes first.

Outcome Measures
Primary Outcome Measures
- Percentage change of urinary N-terminal telopeptide of type 1 collagen/creatine (U-NTX/Cr) from baseline to week 13 [From enrollment to week 13.]
Secondary Outcome Measures
- Incidence and type of adverse events (AEs) [From enrollment to 90 days after the last dose]
- Incidence of Skeletal-related event（SRE） [From enrollment to 90 days after the last dose]
SRE is defined as pathological fracture, radiotherapy to bone, surgery to bone, or spinal cord compression.
- Change in Pain Score (Brief Pain Inventory-Short Form，BPI-SF) [From enrollment to 90 days after the last dose]
- Trough plasma concentration （Ctrough） [From enrollment to 90 days after the last dose]
- Percentage change in serum C-terminus peptide (of Type 1 Collagen) from baseline [From enrollment to 90 days after the last dose]
- Percentage change in serum bone-specific alkaline phosphatase (bALP) from baseline [From enrollment to 90 days after the last dose]
- Number of patients with anti-JMT103 antibodies [From enrollment to 90 days after the last dose]
