Brief Summary:
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.

Primary Outcome Measures :
  1. Safety parameters assessed by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 [ Time Frame: Up to 30 days after last dose ]
    Safety parameters will include severe adverse events, treatment-emergent adverse events, physical examination findings (including Eastern Cooperative Oncology Group performance status), vital sign measurements, and standard clinical laboratory parameters (serum chemistry, hematology, urinalysis). In the Dose Escalation part, the incidence of dose limiting toxicities will also be evaluated.

  2. Incidence of treatment-emergent adverse event (TEAE) assessed by NCI CTCAE version 5.0 [ Time Frame: Up to 30 days after last dose ]
    A TEAE is defined as an adverse event that emerges during the treatment period (from first dose date till 30 [+/- 5] days after the last dosing date), having been absent at pre-treatment; or reemerges during treatment, having been present at baseline but stopped prior to treatment; or worsens in severity after starting treatment relative to the pre-treatment state, when the adverse event is continuous. The number and percentage of subjects reporting TEAEs will be tabulated by the worst NCI-CTCAE grade, system organ class, and preferred term. Similarly, the number and percentage of subjects reporting treatment-emergent severe adverse event (SAE)s will be tabulated, as well as TEAEs/SAEs considered related to treatment.

  3. Change in laboratory test results (hematology and blood chemistry) [ Time Frame: Baseline up to 30 days after last dose ]
    Abnormal laboratory results will be graded according to NCI-CTCAE, version 5.0, if applicable. A shift table, presenting the 2-way frequency tabulation for baseline and the worst post-treatment value according to the NCI-CTCAE grade, will be provided for selected clinical laboratory tests. Abnormal clinical laboratory test results that are deemed of clinical significance or of grade 3 or 4 will be listed.

  4. Change in vital sign [ Time Frame: Baseline up to 30 days after last dose ]
    Descriptive statistics will be provided for the vital signs measurements and changes from baseline by scheduled time of evaluation, including the end-of-treatment visit and the maximum and minimum post-treatment values.


Secondary Outcome Measures :
  1. Pharmacokinetic profile of MDM2 inhibitor AMG-232 assessed by liquid chromatography/tandem mass spectrometric method [ Time Frame: Up to 30 days after last dose ]
    Descriptive statistics will be provided for selected pharmacokinetics, and pharmacodynamics data by dose and time as appropriate. Descriptive statistics on continuous data will include means, medians, standard deviations, and ranges, while categorical data will be summarized using frequency counts and percentages. Graphical summaries of the data may be presented. For MDM2 inhibitor AMG-232 , the individual pharmacokinetic parameters from a single dose will be estimated for concentration maximum (Cmax), area under the curve (AUC), T1/2, apparent Cl/F, and apparent V/F using non-compartmental or compartmental pharmacokinetic methods with the software WinNonlin.

  2. Serum MIC-1 levels [ Time Frame: Up to 30 days after last dose ]
    Each individual level will be normalized to the baseline level for that subject. changes in MIC-1 will be tabulated and descriptive statistics (e.g., geometric means and coefficients of variation) calculated for each dose level. MIC-1 changes will be compared across dose level using nonparametric statistical testing techniques.

  3. Stringent complete response assessed by immunohistochemistry or 2- to 4-color flow cytometry per Clinical Relapse of Multiple Myeloma or Plasma Cell Leukemia (IMWG) criteria [ Time Frame: Up to 30 days after last dose ]
    A two-sided 95% exact binominal confidence interval (CI) will be calculated.

  4. Complete response assessed by flow cytometry or DNA sequencing per IMWG criteria [ Time Frame: Up to 30 days after last dose ]
    A two-sided 95% exact binominal CI will be calculated.

  5. Very good partial response assessed by immunofixation and electrophoresis per IMWG criteria [ Time Frame: Up to 30 days after last dose ]
    A two-sided 95% exact binominal CI will be calculated.

  6. Partial response per IMWG criteria [ Time Frame: Up to 30 days after last dose ]
    A two-sided 95% exact binominal CI will be calculated.

  7. Stable disease per IMWG Uniform Response criteria [ Time Frame: Up to 30 days after last dose ]
    A two-sided 95% exact binominal CI will be calculated.

  8. Minor response per Group for Blood and Marrow Transplantation criteria [ Time Frame: Up to 30 days after last dose ]
    A two-sided 95% exact binominal CI will be calculated.

  9. Myeloma response rate [ Time Frame: Up to 30 days after last dose ]
    The myeloma response rate (responses >= partial response) will also be tabulated by dose cohort and overall.

  10. Time to response [ Time Frame: Up to 30 days after last dose ]
    Time-to-event analyses will be done using Kaplan-Meier analyses.

  11. Progression-free survival (PFS) [ Time Frame: Time from the time of enrollment until documented disease progression, as determined by the Investigator using IMWG uniform response criteria, or death from any cause, whichever occurs first, assessed up to 30 days after last dose ]
    Time to response will be summarized by descriptive statistics by dose cohorts. Kaplan-Meier methods will be used to estimate PFS over time and the median duration of PFS. Subjects with no PFS event will be censored at the date of their last myeloma disease assessment.

  12. Overall survival [ Time Frame: Time from the initial administration of MDM2 inhibitor AMG-232 + KRd to death form any cause, assessed up to 30 days after last dose ]
    Time to response will be summarized by descriptive statistics by dose cohorts. Kaplan-Meier methods will be used to estimate the OS function. Subjects who do not die will be censored at the date that the subject was last known to be alive.
