Experimental: Administration of CC-92328
CC-92328 administered intravenously in 28-day cycles
|
Drug: CC-92328
CC-92328 |
- Dose-Limiting Toxicities (DLTs) [ Time Frame: Up to 28 days after the first dose ]Are defined as toxicities that meet the protocol-specified criteria occurring within the DLT assessment window (Cycle 1, Days 1 to 28) except those that are clearly and incontrovertibly due to the underlying disease or extraneous causes.
- Maximum Tolerated Dose (MTD) [ Time Frame: Up to 12 weeks after the last dose ]Defined as the highest dose at which less than 33% of the population treated with CC-92328 experience a dose-limiting toxicity (DLT) in the first cycle and at least 6 evaluable participants have been treated at this dose level.
- Incidence of Adverse Events (AEs) [ Time Frame: Up to 12 weeks after the last dose ]Type, frequency, seriousness, severity and relationship of AEs to CC-92328.
- Preliminary Efficacy - Overall Response Rate (ORR) [ Time Frame: Up to approximately 2 years ]Defined as the proportion of participants who achieve a partial response (PR) or better according to IMWG response criteria.
- Preliminary Efficacy - Time to response [ Time Frame: Up to approximately 2 years ]Defined as the time from the first CC-92328 dose date to the date of first documented response (PR or better).
- Preliminary Efficacy - Duration of response [ Time Frame: Up to approximately 2 years ]Defined as the time from the earliest date of documented response (≥ PR) to the first documented disease progression or death, whichever occurs first.
- Preliminary Efficacy - Progression-free Survival (PFS) [ Time Frame: Up to approximately 2 years ]Defined as the time from the first dose of CC-92328 to pharmacodynamics (PD) or death from any cause, whichever occurs first.
- Preliminary Efficacy - Overall Survival (OS) [ Time Frame: Up to approximately 2 years ]Defined as the time from the first dose of CC-92328 to death from any cause.
- Pharmacokinetics - Cmax [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Maximum serum concentration of drug.
- Pharmacokinetics - Cmin [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Minimum serum concentration of drug.
- Pharmacokinetics - AUC [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Area under the curve.
- Pharmacokinetics - tmax [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Time to peak (maximum) serum concentration.
- Pharmacokinetics - t1/2 [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Half-life.
- Pharmacokinetics - CL [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Total body clearance of the drug from the serum.
- Pharmacokinetics - Vd [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Volume of distribution.
- Pharmacokinetics - Accumulation index of CC-92328 [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Calculated from the serum concentration-time data of CC-92328 using non-compartment methods.
- Presence of Anti-CC92328 antibodies (ADA) [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Determined using a validated bridging immunoassay with electrochemiluminescence detection.
- Frequency of Anti-CC92328 antibodies (ADA) [ Time Frame: Day 1 to 9 weeks after last dose of study drug ]Determined using a validated bridging immunoassay with electrochemiluminescence detection.
