Study Endpoints

Primary Endpoints

Number of participants with dose limiting toxicities (DLT)
up to 85 days

DLT will be assessed by physical examination, vital signs, ECG, and laboratory values

Determination of the recommended dose of I-131-CLR1404 in treating subjects with relapsed or refractory advanced solid malignancies
Until non-tolerated dose is defined; dose escalation descision made upon review of data from a complete cohort (56 days after all subjects in cohort have received therapy infusion)

Largest administered dose with at most a 20% dose limiting toxicity rate

Secondary Endpoints

Identification of recommended phase 2 dose of I-131-CLR1404 with concurrent weekly dexamethasone
until non-tolerated dose is defined; dose escalation descision made upon review of data from a complete cohort (85 days after all subjects in cohort have received infusion)
Identification of recommended phase 2 dose of I-131-CLR1404 without dexamethasone
until non-tolerated dose is defined; dose escalation descision made upon review of data from a complete cohort (85 days after all subjects in cohort have received infusion)
Identify the recommended dosing schedule of I-131-CLR1404, in relapsed or refractory MM
until non-tolerated dose is defined with both dosing regimens; dose escalation decision made upon review of data from a complete cohort (85 days after all subjects in cohort have received infusion)
