Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | DE Phase: Number of Participants With Dose Limiting Toxicities (DLTs) | Up to 28 days | Criteria for dose-limiting toxicity (DLT) included hematologic indicators such as Grade 3-5 febrile neutropenia and thrombocytopenia with bleeding. Non-hematologic criteria, excluding corneal toxicity, comprise Grade 3-5 toxicities, with exceptions for manageable nausea, vomiting, or diarrhea, controlled Grade 3 hypertension, and events linked to disease progression. Tumor lysis syndrome (TLS) of Grade 3 or 4, successfully managed within 7 days without end-organ damage, was considered. Corneal toxicity, assessed by the GSK corneal grading scale at Grade 4, is a DLT. Other organ-specific toxicities, notably liver toxicity meeting GSK stopping criteria, also qualified as DLTs. Severity was graded using National Cancer Institute (NCI) - Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. |
| Primary | DE Phase: Number of Participants With Adverse Events (AEs) | Up to approximately 253 weeks | An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs were coded using the Medical Dictionary for Regulatory Activities (MedDRA) coding system. |
| Primary | DE Phase: Number of Participants With Worst-case Hematology Results by Maximum Grade Increase Post - Baseline Relative to Baseline | Baseline (Day 1) and up to approximately 253 weeks | Blood samples were collected for evaluation of hematology parameters including Anemia (An), Hemoglobin increased (HbI), Lymphocyte count decreased (LyD), Lymphocytes count increased (LyI), Neutrophils count decreased (NeuD), Platelet count decreased (PD), Leukocytosis (LC) and White blood cell decreased (WBCD). The laboratory parameters were graded according to CTCAE v5.0. Grade 1 (G1): mild; Grade 2 (G2): moderate; Grade 3 (G3): severe; Grade 4 (G4) life-threatening or disabling. Higher grade indicates greater severity and an increase in CTCAE grade was defined relative to the Baseline grade. Any worst-case post baseline increases to G1, G2, G3, and G4 are presented. Baseline value was defined as the most recent, non-missing value from a local laboratory prior to the first dose of study treatment. |
| Primary | DE Phase: Number of Participants With Worst-Case Chemistry Results by Maximum Grade Increase Post - Baseline Relative to Baseline | Baseline (Day 1) and up to approximately 253 weeks | Blood samples were collected for evaluation of clinical chemistry parameters including Hypoglycemia (HG), Hypoalbuminemia (HA), Creatinine Kinase increased (CPKi), Hyperkalemia (HK), Blood lactate dehydrogenase Increased (BLDi), Hypermagnesemia (HyperM), Hypomagnesemia (HypoM), Hypernatremia (HyperN), Hypercalcemia (HyperC), Hypocalcemia (HypoC) and Chronic Kidney Disease (CKD). The laboratory parameters were graded according to CTCAE version 5. G1: mild; G2: moderate; G3: severe; Grade 4 (G4) life-threatening or disabling. Higher grade indicates greater severity and an increase in CTCAE grade was defined relative to the Baseline grade. Any worst-case post baseline increase to G1, G2, G3, and G4 are presented. Baseline value was defined as the most recent, non-missing value from a local laboratory prior to the first dose of study treatment. |
| Primary | CE Phase: Overall Response Rate (ORR) | Up to approximately 253 weeks | Overall Response Rate (ORR) was defined as the percentage of participants with a confirmed Partial Response (PR) or better as the best overall response (i.e., PR, Very Good Partial Response \[VGPR\], Complete Response \[CR\], and stringent Complete Response \[sCR\]), as assessed by the investigator per international myeloma working group (IMWG) (2016). PR is defined as ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 h. VGPR is defined as serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component \<100 mg/24 h. CR is defined as negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow. sCR is defined as CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence. |
| Secondary | DE Phase: Overall Response Rate (ORR) | Up to approximately 253 weeks | Overall Response Rate (ORR) was defined as the percentage of participants with a confirmed Partial Response (PR) or better as the best overall response (i.e., PR, Very Good Partial Response \[VGPR\], Complete Response \[CR\], and stringent Complete Response \[sCR\]), as assessed by the investigator per international myeloma working group (IMWG) (2016). PR is defined as ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 h. VGPR is defined as serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component \<100 mg/24 h. CR is defined as negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow. sCR is defined as CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence. |
| Secondary | CE Phase: Clinical Benefit Rate (CBR) | Up to approximately 253 weeks | Clinical benefit rate was defined as the percentage of participants with a confirmed minimal response (MR) or better according to the IMWG Response Criteria. MR is defined as \>= 25% but \< 49% reduction of serum M-protein and reduction in 24-hour urinary M-protein by 50-89%. |
| Secondary | DE Phase: Number of Participants Achieving Stringent Complete Response (SCR), Complete Response (CR), Very Good Partial Response (VGPR) and Partial Response (PR) | Up to approximately 253 weeks | Partial Response \[PR\], Very Good Partial Response \[VGPR\], Complete Response \[CR\], and stringent Complete Response \[sCR\] as assessed by the investigator per IMWG (2016). PR is defined as ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 h. VGPR is defined as serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component \<100 mg/24 h. CR is defined as negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow. sCR is defined as CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence. |
| Secondary | CE Phase: Number of Participants Achieving SCR, CR, VGPR and PR | Up to approximately 253 weeks | Partial Response \[PR\], Very Good Partial Response \[VGPR\], Complete Response \[CR\], and stringent Complete Response \[sCR\] as assessed by the investigator per IMWG (2016). PR is defined as ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 h. VGPR is defined as serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component \<100 mg/24 h. CR is defined as negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow. sCR is defined as CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence. |
| Secondary | DE Phase: Plasma Concentrations of Belantamab Mafodotin Antibody-Drug Conjugate (ADC) | PRE-DOSE(PD), END OF INFUSION (EOI), EOI+2 HOURS(H), EOI+ 24H on Day(D) 1 of Cycle (C) 1; ANYTIME on C1 D4, D8, D22, and D29 ; PD and EOI on D1 of C2, C4, C6, C9, C12; PD on D1 of C18 and C30; End of Treatment (approximately 157 weeks) | Blood samples were collected for PK analysis of belantamab mafodotin Antibody-Drug Conjugate (ADC). Only those participants who were measured and analyzed (i.e., contributed data reported in the table) were included in the Overall Number of Participants Analyzed field. 'Number Analyzed' signifies participants evaluable for the specified timepoints. |
