Full Description

This is a single arm, multi-institution (1) Hackensack Meridian Health at Hackensack, NJ (2) Jersey Shore Medical Center, Neptune, NJ and (3) Georgetown/Lombardi Cancer Center) phase II study of the combination of pembrolizumab, belantamab, and dexamethasone in patients with triple class refractory multiple myeloma. All institutions will share the same Institutional Review Board.

Safety lead-in Cohort: After the first 10 patients are enrolled, an independent safety review committee will meet to review adverse events and toxicity and determine whether the trial will continue to enroll.

Phase 2 portion: The remainder of patients will be enrolled using a Simon's - 2 stage design.

The study will be conducted in compliance with the International Council for Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good Clinical Practice (GCP) and applicable regulatory requirements.

Patients must have relapsed or must be considered refractory to all of the following:

a proteasome inhibitor,
an immunomodulating agent,
a CD38-monoclonal antibody
an autologous stem cell transplant

Serum free light chain difference > 100 mg/L
Biopsy proven plasmacytoma
Bone marrow involvement >10%

Eastern Cooperative Oncology Group (ECOG) Performance Score 0-1

Adequate hepatic function within 28 days prior to Cycle 1 Day 1 (C1D1):

Total bilirubin < 1.5 × upper limit of normal (ULN) (except patients with Gilbert's syndrome who must have a total bilirubin of < 3 × ULN), and
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) normal to <2 × ULN.
Adequate renal function within 28 days prior to C1D1 as determined by estimated creatinine clearance of ≥ 30 mL/min, calculated using the Cockcroft and Gault formula (140 - Age) • Mass (kg)/ (72 • creatinine mg/dL); multiply by 0.85 if female (Cockcroft

1976). 9) Adequate hematopoietic function within 7 days prior to C1D1: total white blood cell (WBC) count ≥1500/mm3, absolute neutrophil count ≥1000/mm3, hemoglobin ≥8.5 g/dL and platelet count ≥30,000/mm3 (patients for whom <50% of bone marrow nucleated cells are plasma cells)

a. Patients receiving hematopoietic growth factor support, including erythropoietin, darbepoetin, granulocyte-colony stimulating factor (GCSF), granulocyte macrophage colony stimulating factor (GM-CSF), and platelet stimulators (eg, eltrombopag, romiplostim, or interleukin-11) must have a 2-week interval between growth factor support and the Screening assessments, but they may receive growth factor support during the study. b. Patients must have: i. At least a 2-week interval from the last red blood cell (RBC) transfusion prior to the Screening hemoglobin assessment, and ii. At least a 1-week interval from the last platelet transfusion prior to the Screening platelet assessment. However, patients may receive RBC and/or platelet transfusions as clinically indicated per institutional guidelines during the study. 10) Male and Female Participants: A male participant must agree to use a contraception as detailed in Appendix 3 of this protocol during the treatment period and for at least 4 months after the last dose of study treatment and refrain from donating sperm during this period. A female participant is eligible to participate if she is not pregnant (see Appendix 3), not breastfeeding, and at least one of the following conditions applies:

Not a woman of childbearing potential (WOCBP) as defined in Appendix 3 OR
A WOCBP who agrees to follow the contraceptive guidance in Appendix 3 during the treatment period and for at least 4 months after the last dose of study treatment. -

Exclusion Criteria:

Subject has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study

Any of the following laboratory abnormalities (unless there is >50% plasma cell involvement of the bone marrow):

Absolute neutrophil count (ANC) < 1,000/μL
Platelet count < 30,000/μL
Corrected serum calcium > 13.5 mg/dL (> 3.4 mmol/L)
Serum glutamic oxaloacetic transaminase (SGOT)/aspartate aminotransferase (AST) or serum glutamic pyruvic transaminase (SGPT)/alanine aminotransferase (ALT) ≥ 2.5 x upper limit of normal (ULN)
Serum total bilirubin, direct bilirubin, and alkaline phosphatase ≥ 1.5 x ULNf. Subjects with serious renal impairment ([CrCl] < 50 mL/min) or requiring dialysis would be excluded

g. International Normalized Ratio (INR) of >1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants

Subjects with a prior history of malignancies, other than Multiple Myeloma (MM), unless the subject has been free of the disease for ≥ 5 years with the exception of the following noninvasive malignancies:

Subject has received prior systemic anti-cancer therapy including investigational agents within 3 weeks prior to study intervention

Subject has received prior radiotherapy within 2 weeks of start of study intervention.

Participants 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-CNS disease

Subject has received a live vaccine or live-attenuated vaccine within 30 days prior to the first dose of study drug. Administration of killed vaccines is allowed
Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 3 weeks prior to the first dose of study intervention
Subject has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.

Subject has known active Central Nervous System (CNS) metastases and/or carcinomatous meningitis.

Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 3 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 intervention.

Subject has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
Subject has active autoimmune disease that has required systemic treatment in the 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 and is allowed.
Subject has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.

Subject has a known history of Human Immunodeficiency Virus (HIV) infection.

a. Note: No HIV testing is required unless mandated by local health authority.

Subject has active Hepatitis B infection or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection. Note: no testing for Hepatitis C is required unless mandated by local health authority.

Subject has had an allogenic tissue/solid organ transplant
Subject has uncontrolled ocular disease or keratopathy
Subject has uncontrolled cardiovascular disease, specifically uncontrolled hypertension, recent Myocardial Infarction (within 4 months), NYHA Stage 3 or 4 congestive heart failure.
Subject is a WOCBP who has a positive urine pregnancy test within 72 hours prior to first dose of study intervention (see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
Contraindications to the other treatment regimens, as per local prescribing information
Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator. -
