Participants with a history of autologous stem cell transplant are eligible for study participation provided the following eligibility criteria are met: Transplant was >100 days prior to study enrolment; No active infection.
Female participants: Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. A female participant is eligible to participate if she is not pregnant or breast feeding, and at least one of the following conditions applies: Is not a woman of childbearing potential (WOCBP) or For Part 1 and Part 2 Arm A: Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1 percent per year), preferably with low user dependency, during the treatment period and for 4 months after the last dose of GSK2857916, and 7 months from the last dose of bortezomib (only Part 2 Arm A), and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study treatment. A WOCBP must have a negative highly sensitive serum pregnancy test (as required by local regulations) within 72 hours before the first dose of study treatment and agree to use effective contraception during the study and for 4 months after the last dose of GSK2857916, and 7 months from the last dose of bortezomib (only Part 2 Arm A); For Part 2 Arm B: Due to pomalidomide being a thalidomide analogue with risk for embryo-fetal toxicity and prescribed under a restricted distribution program, WOCBP participants will be eligible if they commit either to abstain continuously from heterosexual sexual intercourse or to use 2 methods of reliable birth control, beginning 4 weeks prior to initiating treatment with pomalidomide, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of pomalidomide treatment.

Two negative pregnancy tests must be obtained prior to initiating pomalidomide therapy. The first test should be performed within 10 to 14 days and the second test within 24 hours prior to prescribing pomalidomide therapy. The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
Male participants: Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Male participants are eligible to participate if they agree to the following from the time of first dose of study treatment until 6 months after the last dose of GSK2857916, 4 months after the last dose of bortezomib (only Part 2 Arm A), and 4 weeks after the last dose of pomalidomide (only Part 2 Arm B) to allow for clearance of any altered sperm: Refrain from donating sperm plus either: Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent; or must agree to use contraception/barrier as detailed: Agree to use a male condom even if they have undergone a successful vasectomy and female partner to use an additional highly effective contraceptive method with a failure rate of <1 percent per year as when having sexual intercourse with a woman of childbearing potential (including pregnant females).

Part 2: Number of Participants With Worst-case Change Post-baseline in Hematology Parameters

Blood samples were collected for the analysis of following hematology parameters: Basophils, Eosinophils, MCHC, MCH, MCV, erythrocytes, Hematocrit, monocytes and reticulocytes. The summaries of worst-case change from baseline with respect to normal range was analyzed for only those laboratory tests that were not gradable by CTCAE version 4.03. The number of participants with decreases to low, changes to normal or no changes, and increases to high from baseline values have been presented. Baseline was defined as the latest pre-dose assessment within 21 days prior to first dose with a non-missing value, including those from unscheduled visits.

BG000	Main Study - Part 1: Belantamab Mafodotin 2.5 Milligram/ Kilogram (mg/kg)	Participants with Relapsed or Refractory Multiple Myeloma (RRMM) received belantamab mafodotin as 2.5 milligram (mg)/kilogram (kg) dose via intravenous (IV) infusion on Day 1 of every 21-day cycle (Q3W) maximum up to disease progression.
BG001	Main Study - Part 1: Belantamab Mafodotin 3.4 mg/kg	Participants with RRMM received belantamab mafodotin as dose of 3.4 mg/kg via IV infusion on Day 1 of every 21-day cycle (Q3W) maximum up to disease progression.
BG002	Main Study - Part 2: ArmA-Belantamab Mafodotin 2.5 mg/kg + Bortezomib and Dexamethasone (Bor/Dex)	Participants with RRMM received belantamab mafodotin as dose of 2.5mg/kg via IV infusion on Day 1 of every 21-day cycle (Q3W) maximum up to disease progression. Bortezomib was administered subcutaneously (SC) as 1.3 mg/meter^2 (m^2) on Day 1, Day 4, Day 8, and Day 11 of every 21-day cycle maximum up to 8 cycles. Dexamethasone was administered orally as dose of 20 mg on Day 1, Day 2, Day 4, Day 5, Day 8, Day 9, Day 11, and Day 12 of every 21-day cycle maximum up to 8 cycles.
BG003	Main Study - Part2: ArmB- Belantamab Mafodotin 2.5 mg/kg + Pomalidomide and Dexamethasone (Pom/Dex)	Participants with RRMM received belantamab mafodotin at a dose of 2.5 mg/kg via IV infusion on Day 1 of each 28-day cycle in cycle 1, and at a dose of 1.9 mg/kg from cycle 2 onwards maximum up to disease progression. Along with belantamab mafodotin, Pomalidomide was administered orally as dose of 4 mg per day on Day 1 to Day 21 of 28-day cycles maximum up to disease progression. Dexamethasone orally as dose of 40 mg per day on Day 1, Day 8, Day 15, and Day 22 of each 28-day maximum up to disease progression.
