E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to demonstrate efficacy in terms of prolonged overall survival time (OS) in patients treated with paclitaxel plus ramucirumab (IMC 1121B) drug product (thereafter referred to as ramucirumab DP) compared to patients treated with paclitaxel plus placebo as second-line treatment of metastatic gastric or gastroesophageal adenocarcinoma after failure of any platin and fluoropyrimidine doublet with or without anthracycline (epirubicin or doxorubicin). |
|
E.2.2 | Secondary objectives of the trial |
•To evaluate progression-free survival time (PFS) in each arm
•To evaluate the time to progression (TTP) in each arm
•To evaluate the best overall response (BOR) and objective response rate (ORR) in each arm
•To evaluate the safety profile of ramucirumab DP in combination with paclitaxel
•To evaluate patient-reported outcome (PRO) measures (EORTC QLQ-C30 and EQ-5D)
•To examine the pharmacodynamic profile of ramucirumab DP, with exploratory analysis of pharmacodynamic biomarkers that may predict efficacy of ramucirumab DP, including but not limited to levels of circulating vascular endothelial growth factor A (VEGF-A), VEGF-B, VEGF-C, VEGF-D, placental growth factor (P1GF), soluble vascular endothelial growth factor receptor-1 (VEGFR-1), and soluble VEGFR 2
•To assess the immunogenicity of ramucirumab DP

10. The patient, if female, is surgically sterile, postmenopausal, or compliant with a highly effective contraceptive method (failure rate < 1%) during and for 12 weeks after the treatment period (oral hormonal contraception alone is not considered highly effective and must be used in combination with a barrier method). If male, the patient is surgically sterile or compliant with a highly effective contraceptive regimen during and for 6 months after the treatment period. The label (e.g. SmPC, USPI etc) requirements with regard to the methods and duration of contraception during and after treatment with paclitaxel can differ between countries. Country specific
requirements will apply only if they are more stringent than those already stipulated in the protocol. |
