A Study of Selinexor, in Combination With Carfilzomib, Daratumumab or Pomalidomide in Patients With Multiple Myeloma

Paused · Phase 2

Conditions studied: Multiple Myeloma

In brief

This is a prospective, 2-arm (with an additional exploratory arm), open-label, multicenter study looking at the response rate of patients receiving selinexor (KPT-330), in combination with carfilzomib, daratumumab or pomalidomide. Multiple Myeloma patients with documented disease progression or refractory disease while on current treatment with any carfilzomib-containing regimen (arm 1), any pomalidomide-containing regimen (arm 2) or any daratumumab-containing regimen (exploratory arm) will be included in the study. Patients will be assigned to the respective groups according to their current treatment. If a subject has received more than one of the above therapies, then assignment will be made at their physician's discretion (e.g treatment decision can be made based upon patient and physician preferred tolerance.). Patients will receive treatment until progressive disease (PD), death, toxicity that cannot be managed by standard of care, or withdrawal, whichever occurs first.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥18 years at time of informed consent.
• Histologically confirmed MM and evidence of disease progression while on one of the below MM regimens:
• Arm 1: Refractory to or disease progression while on a carfilzomib-containing regimen
• Arm 2: Refractory to or disease progression while on a pomalidomide-containing regimen
• Exploratory Arm: Refractory to or disease progression while on a daratumumab-containing regimen
• Measurable disease as defined: Serum M-protein ≥ 0.5 g/dL; urine M-protein excretion at least 200 mg/24h; serum FLC ≥ 100 mg/L, provided that FLC is abnormal; if serum protein electrophoresis is felt to be unreliable for routine M-protein measurement (i.e. IgA MM) then quantitative Ig levels by nephelometry or turbidometry are acceptable; for non-secretory disease, bone marrow plasma cells ≥ 20% or a biopsy-proven target lesion by PET/CT or MRI is acceptable
• Documented evidence of disease progression (by IMWG criteria) or refractory disease on the current treatment as defined as:
• Achieving SD or less for ≥ 1 cycle during treatment with regimens stated in #2 (i.e. relapsed) OR
• <25% response (i.e. never achieved MR) or PD during or within 60 days from the end-of most recent MM regimen as listed in #2 (i.e. refractory).
• Any non-hematological toxicities (except for peripheral neuropathy) that patients experienced from treatments in previous regimens have resolved to Grade 2 or less by Cycle 1 Day 1.
• ECOG 2 or less
• Adequate hepatic function within 28 days prior to 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).
• 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 ≥75,000/mm3 (patients for whom <50% of bone marrow nucleated cells are plasma cells) or ≥50,000/mm3 (patients for whom ≥50% of bone marrow nucleated cells are plasma cells).
• Patients receiving hematopoietic growth factor support, including erythropoietin, darbepoetin, granulocyte-colony stimulating factor (G-CSF), 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.
• Patients must have:
• At least a 2-week interval from the last red blood cell (RBC) transfusion prior to the Screening hemoglobin assessment, and
• 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.
• Female patients of childbearing potential must have a negative serum pregnancy test at Screening. Female patients of childbearing potential and fertile male patients who are sexually active with a female of childbearing potential must use highly effective methods of contraception throughout the study and for 3 months following the last dose of study treatment.

You may not qualify if…

• Patients meeting any of the following exclusion criteria are not eligible to enroll in this study:
• Smoldering MM
• Radiation therapy, chemotherapy or immunotherapy other than above stated regimens in #2 ≤2 weeks prior to C1D1. Patients on long-term glucocorticosteroids during screening do not require a washout period. Prior RT is permitted for treatment of fractures or to prevent fractures as well as for pain management.
• Active graft versus host disease after allogeneic stem cell transplant.
• Life expectancy <3 months.
• Known active hepatitis A, B, or C infection; or known to be positive for hepatitis C virus ribonucleic acid (RNA) or hepatitis B virus surface antigen.
• Has any concurrent medical condition or disease (eg, uncontrolled active hypertension, uncontrolled active diabetes, active systemic infection, etc.) that is likely to interfere with study procedures.
• Uncontrolled active infection requiring parenteral antibiotics, antivirals, or antifungals within 1 week prior to Cycle 1 Day 1 (C1D1). Patients on prophylactic antibiotics or with a controlled infection within 1 week prior to C1D1 are acceptable.
• Known intolerance, hypersensitivity, or contraindication to glucocorticoids.
• Pregnant or breastfeeding females.
• Body surface area (BSA) <1.4 m2 at baseline, calculated by the Dubois (Dubois 1916) or Mosteller (Mosteller 1987) method.
• Any active gastrointestinal dysfunction interfering with the patient's ability to swallow tablets, or any active gastrointestinal dysfunction that could interfere with absorption of study treatment.
• Inability or unwillingness to take supportive medications such as anti-nausea and anti-anorexia agents as recommended by the National Comprehensive Cancer Network® (NCCN) Clinical Practice Guidelines in Oncology (CPGO) (NCCN CPGO) for antiemesis and anorexia/cachexia (palliative care).
• Any active, serious psychiatric, medical, or other conditions/situations that, in the opinion of the Investigator, could interfere with treatment, compliance, or the ability to give informed consent.
• Contraindication to any of the required concomitant drugs or supportive treatments.
• Patients unwilling or unable to comply with the protocol
