A Study of Belantamab Mafodotin (GSK2857916) in Multiple Myeloma Participants With Normal and Varying Degrees of Impaired Renal Function DREAMM12

What's the purpose of this trial?

The purpose of this study is to assess the pharmacokinetics (PK), safety, and tolerability of belantamab mafodotin monotherapy in participants with RRMM, who have had at least 3 lines of prior treatment and have either normal or impaired renal functions.

This trial is currently open and accepting patients.

What will happen during the trial?

Belantamab mafodotin (GSK2857916) is an antibody-drug conjugate (ADC) containing humanized anti- B-cell maturation antigen (BCMA) monoclonal antibody (mAb). Renal impairment is a major complication of multiple myeloma (MM) and majority of MM participants are either at risk or already have renal dysfunction at initial diagnosis. The purpose of this study is to assess the pharmacokinetics (PK), safety, and tolerability of belantamab mafodotin monotherapy in participants with RRMM, who have had at least 3 lines of prior treatment and have either normal or impaired renal functions. The study will consist of two parts: part 1 will include participants with normal/mildly impaired renal function and severe renal impairment and part 2 will include participants with end-stage renal disease (ESRD), where participants are either not undergoing or require hemodialysis. Participants will be administered GSK2857916 at a dose of 2.5 milligram per kilogram (mg/kg) intravenously once in three weeks (Q3W) dosing in Part 1. Based on the Part 1 Safety/Pharmacokinetic (PK) data, Part 2 participants will be administered the dose of either 2.5 mg/kg or 1.9 mg/kg (or other adjusted dose). Participants will be treated with GSK2857916 monotherapy until confirmed disease progression, death, unacceptable toxicity, withdrawal of consent, or end of study, whichever occurs first. This study will include a screening phase, treatment phase, and follow- up phase. The total duration of the study is approximately up to 48 months.

You may be able to join this trial if you:

The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.

Inclusion Criteria:

  • Participants are capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the Informed Consent Form.
  • Male and/or female participants must be 18 years of age or older, at the time of signing the informed consent.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
  • Participants with histologically or cytologically confirmed diagnosis of MM, as defined in International Myeloma Working Group criteria: 1. Has undergone autologous stem cell transplant (SCT) or is considered transplant-ineligible; 2. Has failed at least 2 prior lines of anti-myeloma treatments, including an immunomodulatory drugs (example [e.g.], lenalidomide or pomalidomide) and a proteasome inhibitor (e.g., bortezomib, ixazomib or carfilzomib).
  • Participants has measurable disease with at least one of the following: Serum M-protein >=0.5 grams per deciliter (g/dL) (>=5 grams per liter [g/L]); Urine M-protein >=200 milligrams (mg) per 24 hours (mg/24 h); and Serum free light chain (FLC) assay: Involved FLC level >=10 milligrams per deciliter (mg/dL) (>=100 milligrams per liter [mg/L]) and an abnormal serum FLC ratio (<0.26 or >1.65).
  • Participants with a history of autologous SCT are eligible for study participation provided the following eligibility criteria are met: 1. Transplant was >100 days prior to study enrollment, 2. No active infection(s), and 3. Participant meets the remainder of the eligibility criteria outlined in this protocol.
  • Participants with adequate organ system functions as defined follows: Absolute neutrophil count >=1.0 x 10^9 per liter (/L); Hemoglobin >=7.0 g/dL or 4.9 millimoles per liter (mmol/L); Platelets >= 50 x 10^9/L; Total bilirubin <=1.5 x Upper limit of normal (ULN) (Isolated bilirubin >=1.5 x ULN is acceptable if bilirubin is fractionated and direct bilirubin <35 percent [%]); Alanine aminotransferase <=2.5 x ULN; eGFR, Group 1: normal/ mild impairment >=60milliliter per minute per 1.73 meter square (mL/min/1.73m^2); Group 2: severe 15-29 mL/min/1.73 m^2; Group 3: ESRD (not on dialysis) <15 mL/min/1.73 m^2; Group 4: ESRD (on dialysis) <15 mL/min/1.73 m^2; and left ventricular ejection fraction by echocardiograms >=40%.
  • Main additional inclusion criteria in Group 1 (matched control participants): Matched to at least one severely renal impaired participant by Baseline body weight (+/-20%) and Baseline albumin levels (+/-10%).
  • 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 breastfeeding, and at least one of the following conditions applies: Is not a woman of childbearing potential (WOCBP) OR is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), preferably with low user dependency, during the intervention period and for at least 4 months after the last dose of study intervention 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 intervention. A WOCBP must have a negative highly sensitive serum pregnancy test within 72 hours of dosing on Cycle 1 Day 1 and agree to use highly effective contraception during the study and for 4 months after the last dose of study medication. 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 until 6 months after the last dose of study treatment to allow for clearance of any altered sperm: Refrain from donating sperm and 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 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% per year as when having sexual intercourse with a WOCBP (including pregnant females).
