MDM2 Inhibitor AMG-232, Carfilzomib, Lenalidomide, and Dexamethasone in Treating Patients With Relapsed or Refractory Multiple Myeloma


This phase I trial studies the side effects and best dose of MDM2 inhibitor AMG-232 when given together with carfilzomib, lenalidomide, and dexamethasone in treating patient with multiple myeloma that has come back of has not responded to previous treatment. Drugs used in chemotherapy, such as MDM2 inhibitor AMG-232, carfilzomib, lenalidomide, and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

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:

  • Subjects must have histologically confirmed diagnosis of multiple myeloma
  • Subjects must have measurable disease, as defined by at least one of the following:
    • Serum monoclonal protein M-protein level >= 0.5 g/dL

    • Involved free light chain level >= 10 mg/dL, along with an abnormal free light chain ratio
  • Subjects must have disease that has relapsed and/or refractory after their most recent therapy, with progressive disease (PD) being defined as an increase of 25% from the lowest response value in any one or more of the following:
    • Serum M-component protein (the absolute increase must be >= 0.5 g/dL) and/or
    • Urine M-component protein (the absolute increase must be >= 200 mg/24 hours) and/or

  • Total bilirubin < 1.5 x institutional upper limit of normal (ULN) (< 2.0 x ULN for subjects with documented Gilbert's syndrome or < 3.0 x ULN for subjects for whom the indirect bilirubin level suggests an extrahepatic source of elevation)

  • Subjects must have normal corrected QT interval (QTc) =< 470 msec (based on average of screening triplicates)
  • Subjects who have received radiation therapy targeting > 10% of the bone marrow space must have completed this at least 2 weeks prior to starting therapy with AMG-232 + KRd
  • Subjects must be able and willing to provide bone marrow biopsies/aspirates as requested by the protocol
  • Subjects must be willing to undergo myeloma genotyping for TP53 mutation, insertion, or deletion at screening
  • Subjects must have an estimated life expectancy of at least 3 months
  • Women of child-bearing potential must agree to use adequate contraception prior to study entry and for the duration of study participation through 5 weeks (women) after receiving the last dose of AMG 232; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 3 months after completion of AMG 232 administration; adequate methods of effective birth control include sexual abstinence (men, women); vasectomy; or a condom with spermicide (men) in combination with barrier methods, hormonal birth control or intrauterine device (IUD) (women)
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

  • Subjects with myeloma that is relapsed and/or refractory to KRd when used in combination defined as progression of disease while on therapy or within 60 days of completing therapy
  • Subjects with a malignancy that contains a non-synonymous mutation, insertion, or deletion in the TP53 gene determined prior to screening; TP53 mutation status at screening is NOT required prior to AMG-232 dosing; however, subjects found to have TP53 mutation and/or deletion from screening bone marrow biopsy as assessed by central deoxyribonucleic acid (DNA) sequencing conducted at Dr. Jeffrey Sklar's laboratory at Yale University Cancer Center, will be removed from study after C1 and continue on standard-of-care KRd alone
  • Subjects who have not recovered from toxicities from prior anti-tumor therapy, defined as not having resolved to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 grade 0 or 1, or to levels dictated in the eligibility criteria with the exception of alopecia (grade 2 or 3 toxicities from prior antitumor therapy that are considered irreversible [defined as having been present and stable for > 6 months], such as grade 2 chemotherapy-induced peripheral neuropathy, may be allowed if they are not otherwise described in the exclusion criteria AND there is agreement to allow by both the investigator and sponsor)

  • Subjects with history of allergic reactions attributed to compounds of similar chemical or biologic composition to AMG 232 or carfilzomib, lenalidomide, or dexamethasone
  • All herbal medicines (e.g., St. John's wort), vitamins, and supplements consumed by the subject within the 30 days prior to receiving the first dose of AMG 232, and continuing use, if applicable, will be reviewed by the principal investigator
  • Use of any known CYP3A4 substrates with narrow therapeutic window (such as alfentanil, astemizole, cisapride, dihydroergotamine, pimozide, quinidine, sirolimus, or terfanide) within the 14 days prior to receiving the first dose of AMG 232 is not permitted; other medications (such as fentanyl and oxycodone) may be allowed per investigator's assessment/evaluation
  • Treatment with medications known to cause QTc interval prolongation within 7 days of study day 1 unless is not permitted unless approved by the sponsor; use of ondansetron is permitted for treatment of nausea and vomiting
  • Current use of warfarin, factor Xa inhibitors and direct thrombin inhibitors; Note: low molecular weight heparin and prophylactic low dose warfarin are permitted; PT/PTT must meet the inclusion criteria; subjects taking warfarin must have their INR followed closely

  • Positive hepatitis B surface antigen (HepBsAg) (indicative of chronic hepatitis B), positive hepatitis total core antibody with negative HBsAG (suggestive of occult hepatitis B), or detectable hepatitis C virus RNA by a polymerase-chain reaction (PCR) assay (indicative of active hepatitis C - screening is generally done by hepatitis C antibody [HepCAb], followed by hepatitis C virus RNA by PCR if HepCAb is positive); subjects with hepatitis B virus suppressed on therapy, and previously treated/eradicated hepatitis C virus are eligible for study
  • Human immunodeficiency virus (HIV)-positive subjects positive for human immunodeficiency virus (HIV) are NOT excluded from this study, but HIV-positive subjects must have:
    • A stable regimen of highly active anti-retroviral therapy (HAART)
    • No requirement for concurrent antibiotics or antifungal agents for the prevention of opportunistic infections
    • CD4 count above 250 cells/mcL and an undetectable HIV viral load on standard PCR-based test
  • Men and women of reproductive potential who are unwilling to practice acceptable methods of effective birth control while on study through 5 weeks (women) or 3 months (men) after receiving the last dose of AMG 232; acceptable methods of effective birth control include sexual abstinence (men, women); vasectomy; or a condom with spermicide (men) in combination with barrier methods, hormonal birth control or IUD (women)
