What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 52 participants in total. It began in 2023-01-09 with a primary completion date of 2026-12.

Brief Summary

This is a Multi-Center, Phase II/III, open-label, single dose level (6 mg/kg) basket trial of PRL3-zumab monotherapy in solid cancer patients. The study will consist of a Screening Period (Day - 14 to Day -1) for completion of all screening assessments before the first administration of study treatment, a Treatment Period during which visits will occur every 2-week (PK T1/2 = 12 days ±2 days), once the decision to discontinue treatment for any reason, an End of Treatment (EOT) visit will be performed within 14 days ±4 days after last dose of study treatment. Safety Follow-up/EOS visit will be performed 28 days ±2 days after last dose of study treatment and survival follow-up call will be performed every month up to 6 months after EOS visit. PRL3-zumab will be administered by intravenous (i.v.) infusion till patient meets discontinuation criteria (progressive disease, clinically or per iRECIST, intolerable toxicity or withdrawal of consent). One cycle of treatment will be 4-weeks (2 infusions, 12 days±2 days apart). Patients will undergo safety assessment including laboratory tests prior to each infusion. Efficacy will be assessed by iRECIST at baseline and every 4 doses after study treatment. QoL assessments will be performed at Screening and every 4 doses ±7 days during treatment. A patient will be discontinued from study treatment if the patient progress clinically or per iRECIST criteria, or for intolerable toxicity, or if the patient withdraws consent. An EOT visit will be performed within14 days ±4 days after last study treatment dose.
