Tiltaksbeskrivelse
Tidsramme
Therapeutic - RYZ801
Tidsramme: Rate of DLTs during the first 42 days of study treatment

To determine the RTA of RYZ801 in subjects with GPC3+ unresectable HCC (Dose Escalation only)
Rate of DLTs during the first 42 days of study treatment
Therapeutic - RYZ801
Tidsramme: From enrollment for up to three months or study discontinuation, whichever occurs first.

To determine if treatment with RYZ801, compared to SoC therapy, improves ORR in subjects with GPC3+ unresectable HCC (Dose Expansion Stage 2 only) using ORR (rate of CR or PR), as determined by BICR according to RECIST v1.1
From enrollment for up to three months or study discontinuation, whichever occurs first.
Therapeutic - RYZ801
Tidsramme: From enrollment to 3months after randomization or study discontinuation, whichever occurs first.

To evaluate ORR of RYZ801 different dosing regimens (Dose Expansion Stage 1 only) and determine dosage optimized RP2D using ORR (rate of confirmed CR or PR) by RECIST v1.1 per investigator assessment
From enrollment to 3months after randomization or study discontinuation, whichever occurs first.
Diagnostic - RYZ811
Tidsramme: Baseline, pre-injection and post-injection up to 6 days post injection.

To assess the safety and tolerability of RYZ811 in subjects with unresectable HCC. Safety and tolerability of RYZ811 as measured by incidence and severity of AEs, including SAEs, laboratory changes, and other safety findings.
Baseline, pre-injection and post-injection up to 6 days post injection.
Diagnostic - RYZ811
Tidsramme: RYZ811 biodistribution to be assessed on the day of injection.

To evaluate the biodistribution of RYZ811 in subjects with unresectable HCC. SUV (mean, maximum and peak) of organs and tumors; volume of RYZ811 avid uptake in tumor lesions; and tumor-to-normal organ tracer uptake ratios.
RYZ811 biodistribution to be assessed on the day of injection.
