Study Overview
Brief Summary
The aim of the study is to assess the efficacy and safety of the BCD-248 in combination with daratumumab versus the combination of daratumumab, pomalidomide, and dexamethasone in the treatment of relapsed or refractory multiple myeloma. The study will be conducted in a population of male and female subjects aged 18 years and older, with confirmed symptomatic multiple myeloma with measurable disease, who have received one prior line of therapy that included a proteasome inhibitor and lenalidomide and were refractory to lenalidomide, or who have received two or three prior lines of therapy that included a proteasome inhibitor and lenalidomide, with disease progression during or after the last line of therapy.

Inclusion Criteria
- •Signed informed consent form.
- •Age ≥18 years.
- •Documented diagnosis of multiple myeloma according to the IMWG criteria.
- •Measurable disease at screening.
- •At least 1, but not more than 3 prior lines of antimyeloma therapy, including lenalidomide and a proteasome inhibitor.
- •Documented progression according to the IMWG criteria during or after the last line of therapy.
- •ECOG score 0-
- •Resolution of symptoms of toxicity on the prior line of therapy.
Exclusion Criteria
- •Prior therapy with anti-BCMA or anti-CD3 drugs, pomalidomide.
- •Refractory to anti-CD38 monoclonal antibodies according to the IMWG criteria.
- •Use of any investigational products or medical devices within 28 days prior to randomization or planned use of investigational products or medical devices during participation in this study.
- •Hematopoietic stem cell transplantation - prior to randomization or planned during the study
- •Plasmapheresis within 14 days prior to randomization.
- •Administration of a live attenuated vaccine within 28 days prior to randomization.
- •A history of myelodysplastic syndrome or other malignancies other than multiple myeloma within 5 years prior to screening.
- •Life-threatening acute complications of the underlying disease.
- •Concomitant diseases and/or conditions that significantly increase the risk of AEs during the study:
- •Stable angina pectoris, functional class III-IV.
- •Unstable angina pectoris and/or myocardial infarction within 6 months prior to randomization.
- •Congestive heart failure, NYHA class III-IV.
- •Clinically significant (according to the Investigator) cardiac arrhythmia and conduction disorders that do not respond to the maximum possible antiarrhythmic therapy (therapy must be stable for 4 weeks before the planned start of the study therapy).
- •Moderate to severe asthma, uncontrolled asthma, asthma with forced expiratory volume in 1 second <50% of predicted normal.
- •Chronic obstructive pulmonary disease with forced expiratory volume in 1 second <50% of predicted normal.
- •A history of angioneurotic edema, severe respiratory failure.
- •Active autoimmune diseases. Patients with type 1 diabetes mellitus and hypothyroidism, requiring only hormone replacement therapy, as well as with skin diseases (vitiligo, alopecia, psoriasis, etc.), which do not require systemic therapy, are allowed to participate.
- •Thromboembolic (deep vein thrombosis, pulmonary embolism) or cerebrovascular (stroke, transient ischemic attack) events within 6 months prior to randomization.
- •Any infection within 14 days prior to randomization that requires systemic etiological therapy or may, in the Investigator's opinion, increase the risk of infectious complications.
- •Any other concomitant disease or condition, which, in the Investigator's opinion, significantly increases the risk of AEs in the study.
- •Subjects with amyloidosis, POEMS syndrome, plasma cell leukemia
- •CNS involvement or clinical signs of meningeal involvement of multiple myeloma.
- •HIV infection, active HBV infection, hepatitis C.
- •Hypersensitivity, allergy, or intolerance to monoclonal antibodies or any component of BCD-248, daratumumab, pomalidomide, or dexamethasone.
- •Major surgery within less than 14 days prior to the expected start of the study therapy, incomplete recovery from surgery, or planned surgery during participation in the study.
- •Pregnancy or breastfeeding, as well as intention to become pregnant or father a child during the study period and within 180 days after receiving the last dose of the IP.
