Safety, Tolerability and PK/PD of JMT103 in Patients With Bone Metastases From Tumors
Study Details
Study Description
Brief Summary
JMT103 is a novel, full human IgG4 monoclonal antibody targeting RANKL. In preclinical studies, JMT103 demonstrated strong activity through blocking RANKL receptor, RANK on the surface of osteoclasts, leading to inhibit osteoclast differentiation, activation, and maturation and reduce bone resorption.
This first-in-human study is conducted to assess the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) ,to evaluate the safety, pharmacokinetics and preliminary efficacy (bone turnover markers) of recombinant fully human Anti-RANKL Monoclonal Antibody (JMT103) in patients with bone metastases from tumors at single doses and multiple doses.
About 36 cases patients are to be recruited.

Phase 1 |
Detailed Description
This is a Phase I, first-in-human, multi-center, open-label dose escalation clinical study of recombinant fully human Anti-RANKL Monoclonal Antibody (JMT103) administered subcutaneously to patients with bone metastases from tumors.
The study includes two phases: dose escalation study and expansion study. The dose-escalation stage is designed to evaluate the safety, tolerability, and pharmacokinetics of single dose and following repeat doses of JMT103 given every 4 weeks (Q4W) for three times. The expansion study stage is designed to evaluate the safety, tolerability, and pharmacokinetics of repeat doses of JMT103 given every 4 weeks (Q4W) for three times.
