Eligibility criteria

Key Inclusion Criteria:

  • Diagnosis of active seropositive disease
  • after ≥2 prior/ongoing treatments
  • Body weight ≥ 50 kg
  • Willing to comply with and study requirements and procedures

Key Exclusion Criteria:

  • Previous treatment with a BCMA-targeted therapy
  • infection within 3 months of screening
  • Major surgery within 3 months of screening or planned during the study
  • Pregnant or breastfeeding
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
