TrasGEX™: Dose Escalation Study - Full Text View

Purpose

This is a prospective, open label, multicenter study evaluating the safety, tolerability and pharmacokinetics of TrasGEX™ after intravenous administration in patients with HER-2 positive cancers. The effect of TrasGEX™ on the development of anti-drug antibodies and on tumour response will also be evaluated.

Primary Outcome Measures:

optimal dose and regimen of TrasGEX™ [ Time Frame: up to at least 8 weeks after the first TrasGEX™ administration ]
The primary objective of this first-in-man study is to determine the optimal dose and regimen of TrasGEX™ in patients with locally advanced or metastatic human epidermal growth factor receptor-2 (HER-2)-positive cancer. The recommended phase II dose needs to have an acceptable safety profile and provides evidence for efficacy based on clinical observations or the pharmacokinetic profile.

Secondary Outcome Measures:

To determine preliminary evidence of activity [ Time Frame: approx. every 8 weeks ]
CT or MRI imaging will be performed. Assessment of tumor response (SD, PR, CR. PD) will be performed following a modified version of the revised RECIST guidelines, version 1.1. Basically, patients will receive treatment with TrasGEX™ until progression of disease and/or unacceptable toxicities are observed.
safety and tolerability of TrasGEX™ [ Time Frame: until 4 weeks after the last treatment with TrasGEX™ ]
To assess the safety and tolerability of TrasGEX™ in patients with advanced and/or metastatic HER-2-positive cancer at various dose levels considering observed adverse events, laboratory values, vital signs, ECOG performance status and physical examination.
To assess the pharmacokinetic (PK) profile of TrasGEX™ (part I) [ Time Frame: prior to 1st infusion until the end of 5th infusion ]
c(max): to determine the PK profile samples will be taken before the first infusion and up to 24 h after after infusion, followed by weekly samples for the first infusion and samples immediately before and after infusion for the following infusions
To assess the pharmacokinetic (PK) profile of TrasGEX™ (part II) [ Time Frame: prior to 1st infusion until the end of 5th infusion ]
t(1/2): to determine the PK profile samples will be taken before the first infusion and up to 24 h after after infusion, followed by weekly samples for the first infusion and samples immediately before and after infusion for the following infusions
