Gastroesophageal Junction Adenocarcinoma
Interventions
Registration Number
NCT03707028
Lead Sponsor
Elevar Therapeutics
Brief Summary

This is an open-label, single-center, single-arm, dose escalation and dose expansion Phase I/IIa study designed to determine the recommended Phase 2 dose (RP2D) and the safety and tolerability profile along with preliminary signs of efficacy of rivoceranib in combination with paclitaxel as a second-line therapy in advanced, recurrent and/or metastatic gastric or gastroesophageal junction cancer. This study will also characterize the pharmacokinetic (PK) parameters of rivoceranib and paclitaxel when given in combination.

Detailed Description

Primary Phase I Objectives

* To determine the RP2D dose of rivoceranib in combination with paclitaxel.

Primary Phase II Objectives

* To determine clinical activity of the combination of rivoceranib and paclitaxel.

Secondary Phase I Objectives

* To evaluate the PK of rivoceranib and paclitaxel when given in combination.

* To assess the efficacy of rivoceranib in combination with paclitaxel.

Secondary Phase II Objectives

* To assess the efficacy of rivoceranib in combination with paclitaxel.

* To assess the safety and tolerability of rivoceranib in combination with paclitaxel.

* To assess the PK of rivoceranib and paclitaxel when given in combination.

Rivoceranib with PaclitaxelRivoceranibParticipants will receive oral daily doses of rivoceranib per 28-day cycle (as its mesylate salt) with a fixed dose of paclitaxel given intravenously on Day 1, Day 8, and Day 15 of the 28-day cycle.
Rivoceranib with PaclitaxelPaclitaxelParticipants will receive oral daily doses of rivoceranib per 28-day cycle (as its mesylate salt) with a fixed dose of paclitaxel given intravenously on Day 1, Day 8, and Day 15 of the 28-day cycle.
Primary Outcome Measures
NameTimeMethod
Phase I: Incidence of Dose-Limiting Toxicities (DLT) During Cycle 1Cycle 1 (first 28 days)

The number and proportion of participants experiencing DLTs will be reported by dose level, based on DLT observations during Cycle 1. Each Cycle is 28 days.

Phase I: Number of Participants Reporting Adverse Events (AEs) and Serious AEs (SAEs)Up to 24 months

An AE is any untoward medical occurrence in a participant or participant temporally associated with the use of study treatment, whether or not considered related to the study treatment. An SAE is defined as any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect, or important medical events that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent 1 of the other outcomes listed above.

Phase II: Objective Response Rate (ORR)Every other cycle (each cycle is 28 days) until end of study, assessed up to 24 months

ORR is the percentage of participants who achieve objective tumor response (complete response \[CR\] or partial response \[PR\]) by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria for response.

Secondary Outcome Measures
NameTimeMethod
Phase I: Time to Maximum Observed Concentration (tmax)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Area Under the Plasma Concentration-time Curve From Time 0 to Time of the Last Quantifiable Concentration (AUC0-t)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Maximum Observed Concentration (Cmax)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Area Under the Plasma Concentration-time Curve From Time 0 Extrapolated to Infinity (AUC0-∞)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Terminal Half-life (t1/2)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Apparent Oral Plasma Clearance (CL/F)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Apparent Volume of Distribution (Vz/F)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: ORREvery other cycle (each cycle is 28 days) until end of study, assessed up to 24 months

ORR by RECIST 1.1

Phase I: Terminal Rate Constant (λz)Day 1 & 15 of Cycle 1 (each cycle is 28 days)
Phase I: Progression-free Survival (PFS)Every other cycle (each cycle is 28 days) until end of study, assessed up to 24 months

Defined as time from first dose of study drug (Cycle 1 Day 1) to the time of first documented disease progression or death due to any cause.

Phase I: Overall survival (OS)Ongoing assessment from enrollment until end of study, up to approximately 24 months

OS is the time from first dose of study drug (Cycle 1 Day 1) to the time of death from any cause.
