Multiple Myeloma
Conditions
Brief summary
All subjects will receive GR1803 injection until intolerable toxicity or investigator-assessed disease progression occurs (except in cases of disease progression due to discontinuation of the drug as a result of an adverse event) or until the subject has been administered the drug for 2 years or until the subject withdraws consent or until the investigator determines that the subject needs to be discontinued.
Interventions
D1 given at a dose of 30ug/kg, D4 given at a dose of 90ug/kg, D8 given at a dose of 180ug/kg, followed by weekly dosing up to cycle 9, and cycle 10 and onwards, every 2 weeks, with a dosing cycle of every 4 weeks
