A Study of ION251 Administered to Patients With Relapsed/Refractory Multiple Myeloma
Study Details
Study Description
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.

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.

Outcome Measures
Primary Outcome Measures
- Maximum-Tolerated Dose (MTD) [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
- Recommended Phase 2 Dose (PR2D) [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
- Safety and Tolerability as Measured by the Incidence of TEAEs [Up to 28 days from the last dose of study drug]
- Incidence of Abnormal Laboratory Values and Vital Signs [Up to 28 days from the last dose of study drug]
- Cmax: Maximum Observed Concentration ION251 [From Baseline up to 28 days from the last dose of study drug]
- AUC[0-t]: Area Under the Plasma Concentration-Time Curve from Hour zero to t of ION251 [From Baseline up to 28 days from the last dose of study drug]
- t1/2: Distribution Half-life of ION251 [From Baseline up to 28 days from the last dose of study drug]
- Trough Concentration of ION251 [From Baseline up to 28 days from the last dose of study drug]
- Urine 0-24 Hour (hr) Excretion of ION251 [Up to 12 months from the last dose of study drug]
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Aged ≥ 18 years at the time of informed consent
-
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
-
Measurable multiple myeloma (MM)
-
In need of systemic treatment for MM and either is refractory to or has failed treatment with, is intolerant to or has refused, or is not otherwise a candidate in the opinion of the Investigator, for any of the currently available established therapies known to provide clinical benefit in relapsed/refractory MM. Refractory to treatment is defined as documented MM disease progression while on or within 60 days from the last dose (LD) of treatment
Exclusion Criteria:

-
Absolute neutrophil count ≤ 1.0 1000/cubic millimeter (k/mm^3)
-
Platelet count < 50 k/mm^3
-
Hemoglobin < 8.0 g/dL
-
Estimated glomerular filtration rate (eGFR) < 50 milliliters per minute (mL/min)/1.73 square meter (m^2)

-
Uncontrolled hypertension (systolic pressure ≥ 160 mm of mercury (mm Hg) and/or diastolic pressure ≥ 100 mm Hg)
-
Presence of a bleeding disorder or an underlying disease state associated with active bleeding.
