Brief Summary:
The purpose of this study is to determine the maximum-tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of ION251 in patients with relapsed/refractory multiple myeloma.

Condition or disease Intervention/treatment Phase
Relapsed Multiple Myeloma Refractory Multiple Myeloma Drug: ION251 Phase 1

Detailed Description:
This is a two-part, multi-center first in human study of ION251 in up to 80 participants. Part 1 will use a 3+3 dose-escalation scheme in sequential cohorts to determine the MTD and RP2D during repeated 28-day treatment cycles. MTD will be determined by the number of participants with AEs meeting the dose-limiting toxicity (DLT) criteria during Cycle 1. The MTD determined in Part 1 will be used with other variables to inform a RP2D for participants proceeding to Part 2 for further assessments in the safety, tolerability and anti-myeloma activity.

Arm Intervention/treatment
Experimental: ION251
In Part 1, the dose escalation phase, increased amounts of ION251 will be administered at multiple time points by intravenous (IV) infusion during 28-day cycles. In Part 2, the determined RP2D of ION251 will be administered at multiple time points by IV infusion.
Drug: ION251
ION251 administered by IV infusion

Primary Outcome Measures :
  1. Maximum-Tolerated Dose (MTD) [ Time Frame: Up to 28 days from the last dose of study drug in Cycle 1 (each cycle is 28 days) ]
    MTD is defined as the maximum dose at which ≤ 1 of 3 evaluable participants experiences a dose-limiting toxicity (DLT) within Cycle 1 and there are 2 of 3 or 2 of 6 evaluable participants in the next higher-dose level experiencing a DLT within Cycle 1. If no dose in the dose-escalation has 2 of 3 or 2 of 6 evaluable participants experiencing a DLT, the highest dose level is considered the MTD

  2. Recommended Phase 2 Dose (PR2D) [ Time Frame: Up to 28 days from the last dose of study drug ]
    RP2D is chosen based on the dose response and exposure-response analyses of the pooled clinical PK, PD, safety results, and anti-myeloma activity from both Part 1 and Part 2

Secondary Outcome Measures :
  1. Safety and Tolerability as Measured by the Incidence of TEAEs [ Time Frame: Up to 28 days from the last dose of study drug ]
  2. Incidence of Abnormal Laboratory Values and Vital Signs [ Time Frame: Up to 28 days from the last dose of study drug ]
  3. Cmax: Maximum Observed Concentration ION251 [ Time Frame: From Baseline up to 28 days from the last dose of study drug ]
  4. AUC[0-t]: Area Under the Plasma Concentration-Time Curve from Hour zero to t of ION251 [ Time Frame: From Baseline up to 28 days from the last dose of study drug ]
  5. t1/2: Distribution Half-life of ION251 [ Time Frame: From Baseline up to 28 days from the last dose of study drug ]
  6. Trough Concentration of ION251 [ Time Frame: From Baseline up to 28 days from the last dose of study drug ]
  7. Urine 0-24 Hour (hr) Excretion of ION251 [ Time Frame: Up to 12 months from the last dose of study drug ]
