Safety Objective for phase II and III:
• To evaluate the safety and tolerability of ramucirumab plus FOLFIRI or paclitaxel
Secondary Objectives for the phase II part of the study:
To compare treatment arms with respect to
• Progression-free survival
• Objective response rate (CR + PR)
• Tumor control rate (CR, PR, SD)
• Assessment of quality of life during treatment and follow-up. |

| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Signed written informed consent
2. 2. Male or female* ≥ 18 years of age; Patients in reproductive age must be willing to use adequate contraception (that results in a failure rate of <1% per year) during the study and for 3 months after the end of ramucirumab treatment (appropriate contraception is defined as surgical sterilization (e.g. bilateral tubal ligation, vasectomy), hormonal contraception (including oral contraceptive pills (combination of estrogen and progesterone), vaginal ring, injectables, implants, intrauterine devices (IUDs) and intrauterine hormone-releasing system (IUS)), nonhormonal IUDs and complete abstinence). Female patients with childbearing potential need to have a negative pregnancy test within 7 days before study start.
* There are no data that indicate special gender distribution. Therefore, patients will be enrolled in the study gender-independently.
3. Histologically proven gastric adenocarcinoma including adenocarcinoma of the esophagogastric junction
4. Metastatic or locally advanced disease, not amenable to potentially curative resection
5. Phase II only: Documented objective radiological or clinical disease progression during or within 6 months of the last dose of first-line platinum and fluoropyrimidine doublet with or without anthracycline or docetaxel. Neoadjuvant/adjuvant treatment is not counted unless progression occurs <6 months after completion of the treatment. In these cases neoadjuvant/adjuvant treatment is counted as one line.
OR
Phase III only: Radiological or clinical disease progression during or after the last dose of a first-line platinum, fluoropyrimidine-containing therapy. Patients must also have received a taxane with the first-line or during their adjuvant or neoadjuvant therapy or both. Neoadjuvant/adjuvant platinum containing therapy is permitted and is counted as first-line therapy if progression occurs <12 months after completion of the treatment. If progression occurred ≥ 12 months after completion of neoadjuvant/adjuvant therapy, the therapy is not counted as a treatment line. At decision of the investigator, different regimens can be considered as one line of prior treatment, in case these were administrated as a sequential or alternating therapy.

• Urinary protein ≤1+ on dipstick or routine urinalysis (UA; if urine dipstick or routine analysis is ≥2+, a 24-hour urine collection for protein must demonstrate <1000 mg of protein in 24 hours to allow participation in this protocol)

| E.5 End points |
| E.5.1 | Primary end point(s) |
Primary endpoint for phase II:
OS rate after 6 months, based on an ITT population. The experimental therapy (FOLFIRI + Ramucirumab) would be considered to be a highly promising candidate for further development (e.g. in a phase III trial), if the true OS rate amounted to 65% or more, as this corresponds to the efficacy of the standard Ramucirumab-Paclitaxel regimen according to the RAINBOW (Wilke et al., 2014) study in the western population.
The OS rate achieved will be evaluated in view of the calibration arm Ramucirumab + Paclitaxel.
Co-Primary Endpoints for phase III:
• Overall Survival (OS) defined as the time from randomization to death from any cause and assessed according to Kaplan-Meier

Database closure is defined as the end of the trial: Sites need to collect survival data of patients and are involved in the data cleaning process actively (e.g. additional source data may be requested and additonal monitoring visits may be neccessary). Therefore, database closure is considered the end of the trial.
