Trial outcomes

Primary outcomes

1

Phase Ia: Dose limiting toxicity (DLT)

DLTs are assessed according to NCI-CTCAE v5.0 during the first cycle and defined as occurrence of any of the toxicities in DLT definition if judged by the investigator to be possibly, probably or definitely related to study drug administration.

Time frame
Up to 42 days after the first dose
2

Phase Ia: Maximum tolerated dose (MTD)

MTD is defined as the highest dose level at which no more than 1 in 6 participants experienced a DLT during the first cycle.

Time frame
Up to 42 days after the first dose
3

Phase Ib: Recommended Phase II Dose (RP2D)

The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for phase II study, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation study of Lutetium \[177Lu\] BL-ARC001.

Time frame
Up to approximately 24 months

Secondary outcomes

1

Treatment-Emergent Adverse Event (TEAE)

TEAE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally emerging, or any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition during the treatment of Lutetium \[177Lu\] BL-ARC001. The type, frequency and severity of TEAE will be evaluated during the treatment of Lutetium \[177Lu\] BL-ARC001.

Time frame
Up to approximately 24 months
2

Cmax

Maximum serum concentration (Cmax) of Lutetium \[177Lu\] BL-ARC001 will be investigated.

Time frame
Up to approximately 24 months
3

Tmax

Time to maximum serum concentration (Tmax) of Lutetium \[177Lu\] BL-ARC001 will be investigated.

Time frame
Up to approximately 24 months
4

T1/2

Half-life (T1/2) of Lutetium \[177Lu\] BL-ARC001 will be investigated.

Time frame
Up to approximately 24 months
