• Prior treatment with any antibody targeting BCMA.
• Diagnosed or pretreated for an invasive malignancy other than multiple myeloma.
• Prior anti-tumor treatment (before pretreatment) with insufficient washout period.
• Known active, or prior history of central nervous system (CNS) involvement, or clinical signs of membrane/spinal membrane involvement of multiple myeloma.

Más betegség

• Positive of any hepatitis B surface antigen (HBsAg), hepatitis B virus deoxyribonucleic acid (HBV DNA), hepatitis C antibody (HCV-Ab), hepatitis C virus ribonucleic acid (HCV RNA), human immunodeficiency virus antibody (HIV-Ab) at the time of screening.
• Serious underlying medical conditions
• The investigator considered that the subjects were not suitable for any conditions of participation in the study.

Egyéb

• Male subjects who have a birth plan during the study period or within 1 year after the study treatment.
• Female subjects who are pregnant, breast-feeding, or plan to become pregnant during the study period or within 1 year after the study treatment.

• Subjects ≥ 18 years of age.
• Documented initial diagnosis of MM according to IMWG diagnostic criteria.
• Presence of measurable disease at screening.
• Received a PI and an IMiD (except thalidomide).
• Received at least 3 prior lines of therapy for multiple myeloma, undergone at least 1 complete cycle of treatment for each line, unless progressive disease (PD) was documented by IMWG criteria as the best response to the regimen. Also, subjects refractory or intolerant to any PI and any IMiD in their previous treatment afterwards are eligible.
• Expected survival ≥ 3 months.
