Efficacy and Safety of JMT103 in Patients With Giant Cell Tumor of Bone

Giant Cell Tumor of Bone Clinical Trial

Official title:
A Phase Ib/II, Multicenter, Single-Arm, Open-Label Study to Evaluate the Efficacy and Safety of JMT103 in Surgically Unsalvageable or Refractory Giant Cell Tumor of Bone

Clinical Trial Summary

This is a phase Ib/II, multicenter, single-arm, open-label study to evaluate the efficacy and safety of JMT103 in patients with surgically unsalvageable or refractory giant cell tumor of bone (GCTB).

Clinical Trial Description

The objective of the trial is to evaluate the efficacy and safety of JMT103 in patients with GCTB that is surgically unsalvageable or for which the planned surgery is associated with severe morbidity. This study consists of two parts (phase Ib and II). In the phase Ib part, 6 to 12 subjects will be enrolled, and the safety, pharmacokinetics and pharmacodynamics of JMT103 will be evaluated after treatment for more than 4 weeks. And then the phase II part will be conducted, in which, 125 subjects will be enrolled. Eligible subjects will receive JMT103 at a dose of 2mg/kg subcutaneously (SC) every 4 weeks (Q4W) with a loading dose of 2mg/kg SC on study days 8 and 15 until disease progression, tumor resection (the pathologic outcome after surgical resection is CR or PR), intolerable toxicity, decision by the participant to discontinue, or decision by the investigator that the subject could no longer benefit from the treatment (whichever occurs first). ;
