简要总结
This is a phase 1, multi-center, single-arm, open-label study evaluating the safety, tolerability, and anti-myeloma activity of ACTR087 (an autologous T cell product) in combination with SEA-BCMA (a monoclonal antibody) in subjects with relapsed or refractory Multiple Myeloma.

入选标准
- •Signed written informed consent obtained prior to study procedures
- •Histologically- or cytologically-confirmed relapsed or refractory multiple myeloma (MM) with measurable disease
- •Must have received at least 3 prior lines of therapy to include treatment with a proteasome inhibitor (eg, bortezomib, carfilzomib, or ixazomib) and an immunomodulatory agent (eg, lenalidomide, pomalidomide) unless double-refractory to both; and a hematopoietic stem cell transplant (HSCT), for those subjects considered HSCT-eligible.
- •Quantitative serum IgG levels for subjects with IgG MM must not exceed the institutional upper limit of normal (ULN)
- •ECOG 0 or 1
- •Life expectancy of at least 6 months
- •Absolute neutrophil (ANC) count greater than 1000/ µL
- •Platelet count greater than 50,000/µL
- •Estimated GFR >30mL/min/1.73m2
排除标准
- •Known active central nervous system (CNS) involvement by MM
- •Systemic rheumatic or autoimmune diseases or acute or chronic infections
- •Uncontrolled thromboembolic events or recent severe hemorrhage
- •Subjects who are currently using more than 5mg/day of prednisone (or an equivalent glucocorticoid exceeding physiologic replacement levels)
- •Prior treatment as follows:
- •T cell-directed antibody therapy (eg. Alemtuzumab, anti-thymocyte globulin) within 6 months of enrollment
- •Any prior myeloma-directed therapy including cytotoxic chemotherapy, biologic therapy, or radiotherapy within 2 weeks of enrollment
- •Any mAb or other protein therapeutic containing Fc-domains within 4 weeks of enrollment
- •Experimental agents within 3 half-lives prior to enrollment, unless progression is documented on therapy
- •Prior BCMA-directed investigational agents at any time
- •Prior cell or gene therapy, excluding transfers of genetically unmodified autologous cells (eg. Hematopoietic stem cell transplantation), at any time; or prior allogeneic HSCT at any time
- •Pregnant or breastfeeding
