Design outcomes

Primary

MeasureTime frame
Non-Tolerated Dose (NTD): A dose that causes unacceptable side effects18 months
Maximum Tolerated Dose (MTD): The highest dose that does not cause unacceptable side effects18 months
Dose-Limiting Toxicity (DLT): Any adverse events meeting the protocol-defined DLT criteria30 months

Secondary

MeasureTime frame
Progression free survival (PFS): Time from the first dose to the first occurrence of disease progression or death from any cause66 Months
Overall survival (OS): Time from the first dose to death due to any cause66 Months
Pharmacokinetic - Maximum serum concentration of the drug (Cmax)36 Months
Overall response rate (ORR): The percent of participants whose best response is complete response (CR) or partial response (PR)72 Months
Pharmacokinetic - Area under the serum concentration time-curve of the drug (AUC)36 Months
Anti-CC-95251 antibody (ADA) assessment: determine the presence and frequency of anti-drug antibodies36 Months
Pharmacokinetic - Minimum serum concentration of the drug (Cmin)36 Months
Time to response (TTR): Time from the first dose to the first objective tumor response observed for participants who achieved a CR or PR66 Months
Duration of response (DOR): Time from the first objective tumor response observed for participants who achieved a CR or PR until the first date at progressive disease is objectively documented66 Months
