Am I Eligible?

The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.

The following criteria is provided for health care professionals.

Inclusion criteria:

  • Provide signed written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • Male or female, 18 years or older (at the time consent is obtained).
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Subjects must: have histologically or cytologically confirmed diagnosis of Multiple myeloma (MM), as defined by IMWG, 2014 and has undergone stem cell transplant or is considered transplant ineligible, and has been treated with at least 3 prior lines of prior anti-myeloma treatments including an immunomodulatory imide drug (IMiD) (eg. lenalidomide or pomalidomide), a proteasome inhibitor (eg. bortezomib, ixazomib or carfilzomib) and an anti-CD38 antibody alone or in combination. Line of therapy are defined by consensus panel of the International Myeloma Workshop, Has measurable disease defined as one the following: a) Serum M-protein >=0.5 grams per deciliter (g/dL) (>=5 grams per liter [g/L]). b) Urine M-protein ≥200 mg/24h. c) 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 free light chain ratio (<0.26 or >1.65).
  • Subjects with a history of autologous stem cell transplant are eligible for study participation provided the following eligibility criteria are met: a) transplant was > 100 days prior to study enrolment. b) no active infection(s). c) subject meets the remainder of the eligibility criteria.
  • Adequate organ system functions as defined by the laboratory assessments.
  • All prior treatment-related toxicities (defined by National Cancer Institute-Common Toxicity Criteria for Adverse Events [NCI-CTCAE], version 4.03, 2010) must be <= Grade 1 at the time of enrolment except for alopecia and Grade 2 neuropathy.
  • A female subject 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 120 days 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 (as required by local regulations) within 72 hours before the first dose of study intervention. 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 subjects are eligible to participate if they agree to the following during the intervention period and for at least 140 days after the last dose of study intervention. Male subjects should 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 a male condom and female partner to use an additional highly effective contraceptive method with a failure rate of <1% per year when having sexual intercourse with a woman of childbearing potential who is not currently pregnant.

Exclusion criteria:

A subject will NOT be eligible for inclusion in this study if any of the following criteria apply:

  • Systemic anti-myeloma therapy or an investigational drug <=14 days or five half-lives, whichever is shorter, preceding the first dose of study drug
  • Plasmapheresis within 7 days prior to the first dose of study drug
  • Prior treatment with a monoclonal antibody within 30 days of receiving the first dose of study drugs
  • Has received prior therapy with an anti-PD-1, anti-Programmed cell death Ligand 1 (PD-L1), or anti-Programmed cell death Ligand 2 (PD-L2) agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., cytotoxic T-lymphocyte-associated antigen 4 [CTLA-4], OX 40, CD137) and was discontinued from that treatment due to a Grade 3 or higher immune related adverse event (irAE)
  • Current corneal epithelial disease except mild punctate keratopathy
  • Any major surgery within the last four weeks prior to the first dose of study therapy
  • Presence of active renal condition (infection, requirement for dialysis or any other condition that could affect subject's safety). Subjects with isolated proteinuria resulting from MM are eligible, provided they fulfil criteria as per adequate organ system function mentioned under inclusion criteria.
  • Any serious and/or unstable pre-existing medical, psychiatric disorder or other conditions (including lab abnormalities) that could interfere with subject's safety, obtaining informed consent or compliance to the study procedures.
  • Has received prior radiotherapy within 2 weeks of start of study therapy. Subjects must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (<=2 weeks of radiotherapy) to non-central nervous system (CNS) disease.
  • History of (non-infectious) pneumonitis that required steroids, or current pneumonitis
  • Current active liver or biliary disease per investigator assessment defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, persistent jaundice, or cirrhosis.
  • Malignancies other than disease under study are excluded, except for any other malignancy from which the subject has been disease-free for more than 2 years and, in the opinion of the principal investigators and GSK Medical Monitor, will not affect the evaluation of the effects of this clinical trial treatment on the currently targeted malignancy (RRMM). Subjects with curatively treated non-melanoma skin cancer are allowed.
  • Has known active CNS metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study therapy

Subjects with moderate valvular thickening should not be entered on study.
  • Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to GSK2857916 or pembrolizumab, or any of the components of the study treatment.
  • Pregnant or lactating female.

  • Has received a live-virus vaccination within 30 days of planned start of study therapy.
  • Active autoimmune disease that has required systemic treatment in past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
  • Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other chronic form of immunosuppressive therapy within 7 days prior the first dose of study therapy.
  • Has known psychiatric or substance abuse disorder that would interfere with the subject's ability to cooperate with the requirements of the study.
  • Has had an allogenic tissue/solid organ transplant
