A Study to Evaluate the Efficacy and Safety of Narlumosbart (JMT103) in Patients With Giant Cell Tumor of Bone
April 16, 2023 updated by: Shanghai JMT-Bio Inc.
A Multi-center, Randomized, Double-blind, Active-controlled, Phase Ⅲ Study to Evaluate Efficacy and Safety of Narlumosbart (JMT103) in Patients With Giant Cell Tumor of Bone
This is a phase Ⅲ, multi-center, randomized, double-blind, active-controlled study to evaluate the efficacy and safety of narlumosbart (JMT103) in patients with unresectable or surgically difficult giant cell tumor of bone (GCTB).
This clinical trial study hypothesizes narlumosbart administration groups are not inferior to active control administration groups.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Narlumosbart
Patients will receive narlumosbart 120 mg subcutaneously (SC) once every 4 weeks (Q4W) with a loading dose of 120 mg SC on day 8 and day 15 of the first cycle until one of the following occurred: complete tumor resection, disease progression, intolerable toxicity, decision by the patient to discontinue, or decision by the investigator that the patient could no longer benefit from the treatment.
|
Administered by subcutaneous injection.
Dietary Supplement: Calcium/Vitamin D. All patients should be adequately supplemented with calcium and vitamin D (at least 500 mg of calcium and 400 IU of vitamin D), except in the case of pre-existing hypercalcemia.
Other Names:
|
Active Comparator: Denosumab
Patients will receive denosumab 120 mg subcutaneously (SC) once every 4 weeks (Q4W) with a loading dose of 120 mg SC on day 8 and day 15 of the first cycle until one of the following occurred: complete tumor resection, disease progression without clinical benefit, decision by the patient to discontinue, or decision by the investigator that the patient could no longer benefit from the treatment.

Administered by subcutaneous injection.
Dietary Supplement: Calcium/Vitamin D. All patients should be adequately supplemented with calcium and vitamin D (at least 500 mg of calcium and 400 IU of vitamin D), except in the case of pre-existing hypercalcemia.
