Part 1 - Dose Escalation and BackfillsEXPERIMENTALAim: Doses of LNCB74 will be escalated to determine the maximum tolerated dose (MTD), maximum administered dose (MAD) and/or recommended Phase 2 dose (RP2D). One or more dose levels will be backfilled for safety and additional biomarker data.
Part 2 - Dose Expansion / OptimizationEXPERIMENTALAim: The objectives of the Part 2 Dose Expansion/Optimization are: i) to evaluate safety, tolerability, anti-tumor activity, and pharmacodynamics of LNCB74 in a more homogenous population and ii) characterize the minimally safe and effective dose in a particular tumor type and determine recommended Phase 2 dose(s) (RP2D).
Interventions
NameTypeDescription
LNCB74DRUGLNCB74 is an antibody drug conjugate being evaluated as a potential treatment for participants with advanced solid tumors. Participants will receive LNCB74 into the vein (IV; intravenously) in 21-day dosing cycles. Participants will continue treatment in the absence of unacceptable toxicities and unequivocal disease progression.
