Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi-center, Phase 2, open-label, single dose level study of PRL3-zumab monotherapy in patients with unresectable or metastatic solid tumor.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study consists of a Screening Period (Day - 14 to Day -1), a Treatment Period during which visits will occur every 2 weeks, an End of Treatment visit within 14 days of the decision to discontinue treatment for any reason, and a Safety Follow-up visit at 14 ± 4 days after the last dose of study treatment. PRL3-zumab will be administered by intravenous (IV) infusion till patient meets any of the discontinuation criteria (progressive disease, clinically or per RECIST v1.1 and iRECIST, intolerable toxicity or withdrawal of consent). One cycle of treatment will be 4 weeks (2 infusions, 12 days ±2 days apart).
