A Study to Assess Safety and Efficacy of PRL3-Zumab in Patients with Solid Tumors
- Registration Number
- NCT04452955
- Lead Sponsor
- Intra-IMMUSG Pte Ltd
- Brief Summary
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
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).

Group Intervention Description PRL3-zumab PRL3-zumab All patients will receive PRL3-zumab until clinical progression per RECIST v1.1 and iRECIST criteria, or unacceptable toxicity, or withdraws consent.
- Primary Outcome Measures
Name Time Method Progression free survival (PFS) From first dose of study drug until disease progression or end of treatment, whichever comes first PFS is defined as the time from the initiation of study treatment to the date of disease progression as per RECIST v1.1 and iRECIST criteria.
- Secondary Outcome Measures
Name Time Method Objective Response Rate (ORR) Time Frame: From first dose of study drug until disease progression or end of treatment, whichever comes first. Description: ORR is defined as the percentage of patients with complete response (CR) or partial response (PR) as per RECIST v1.1 and iRECIST criteria from time of initiation of study treatment.
Clinical benefit rate (CBR) Time Frame: From first dose of study drug until disease progression or end of treatment, whichever comes first Description: CBR is defined as the percentage of patients with CR, PR, or stable disease (SD) as per RECIST v1.1 and iRECIST criteria based on Investigator's assessment.
Overall survival (OS) Time Frame: From first dose of study drug until disease progression or end of treatment, whichever comes first Description: OS is defined as the time from the initiation of study treatment to death from any cause.
Duration of response Time Frame: From first dose of study drug until disease progression or end of treatment, whichever comes first Description: Duration of response is defined as the time from the initial documented response (CR or PR) to the first documented sign of disease progression as per RECIST v1.1 and iRECIST criteria or death.
Terminal elimination half life (t½) Pre-dose and during first dose of C1, pre dose C1D15, C2D1, C2D15, C3D1, and pre dose and during the second dose of C3, pre-dose C4D1, C5D1, C6D1 and at end of treatment (up to approximately 6 months). Duration of 1 cycle is 4 weeks. C = Cycle, D = Day. To assess PK after single and multiple dose administration of PRL3-zumab.
Maximum plasma PRL3-zumab concentration (Cmax) Pre-dose and during first dose of C1, pre dose C1D15, C2D1, C2D15, C3D1, and pre dose and during the second dose of C3, pre-dose C4D1, C5D1, C6D1 and at end of treatment (up to approximately 6 months). Duration of 1 cycle is 4 weeks. C = Cycle, D = Day. To assess pharmacokinetics (PK) after single and multiple dose administration of PRL3-zumab.
Time of Cmax (tmax) Pre-dose and during first dose of C1, pre dose C1D15, C2D1, C2D15, C3D1, and pre dose and during the second dose of C3, pre-dose C4D1, C5D1, C6D1 and at end of treatment (up to approximately 6 months). Duration of 1 cycle is 4 weeks. C = Cycle, D = Day. To assess PK after single and multiple dose administration of PRL3-zumab.
Area under the concentration time curve from pre-dose (AUCinf) Pre-dose and during first dose of C1, pre dose C1D15, C2D1, C2D15, C3D1, and pre dose and during the second dose of C3, pre-dose C4D1, C5D1, C6D1 and at end of treatment (up to approximately 6 months). Duration of 1 cycle is 4 weeks. C = Cycle, D = Day. To assess PK after single and multiple dose administration of PRL3-zumab.
Number of patients with adverse events and serious adverse events From first dose of study drug until disease progression or end of treatment, whichever comes first To assess safety of PRL3-zumab in patients with unresectable or metastatic solid tumors.
European Quality-5D (EQ-5D) From first dose of study drug until disease progression or end of treatment, whichever comes first The system comprises 5 questions, 1 for each of 5 domains: mobility, self care, usual activities, pain/discomfort, and anxiety/depression. Each is rated according to 3 response levels ("no problems," "some problems," or "extreme problems").
European Organization for Research and Treatment of Cancer-quality of life quantionnaire-C30 (EORTC-QLQ-C30) From first dose of study drug until disease progression or end of treatment, whichever comes first Health-related quality of life is measured by EORTC-QLQ-C30, a 30 item questionnaire. This scale consists of functioning scales and symptom scales. For functioning scales higher scores suggest better functioning; for symptom scales higher scores suggest higher symptom burden.
