E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Phase Ib stage: - To determine the optimal dose of elisidepsin as a single agent administered as a 24-hour intravenous (i.v.) infusion fortnightly or as a 3-hour i.v. infusion weekly to patients with unresectable, locally advanced or metastatic esophageal, esophagogastric junction or gastric cancer who failed one but not more than two prior lines of systemic anticancer therapy. In both study regimens, each cycle will last four weeks. Phase II stage: - To determine the antitumor activity of elisidepsin as a single agent administered as a 24-hour i.v. infusion fortnightly or as a 3-hour i.v. infusion weekly in the study patient population. |
|
E.2.2 | Secondary objectives of the trial |
Phase Ib stage: - To determine the antitumor activity of elisidepsin as a single agent administered as a 24-hour i.v. infusion fortnightly or as a 3-hour i.v. infusion weekly. Both stages: - To characterize the safety profile and feasibility of elisidepsin in patients with unresectable, locally advanced or metastatic esophageal, esophagogastric junction or gastric cancer. - To determine the time-to-event outcomes and response rate. - To characterize the pharmacokinetics (PK) and pharmacodynamics (PDy) of elisidepsin when administered as a single agent in patients with esophageal, esophagogastric junction or gastric cancer. - To perform a preliminary pharmacogenomic (PGx) study to explore potential biological markers of tumor sensitivity/resistance to elisidepsin in patients with esophagogastric cancer. Each of these secondary endpoints will be characterized separately for each study regimen. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Previously available tumor samples from patients treated with elisidepsin will be used to analyze the expression of putative markers of response/resistance to elisidepsin. Available tumor samples from any previous biopsies and/or surgical procedures (paraffin-embedded tissue and/or fresh frozen tissue) will be collected. Participation in the PGx substudy will not subject the patients to any additional procedures. The markers to be analyzed will be selected based on the existing knowledge at the time of analysis, resulting from previous PGx and mechanism of action (MoA) studies. |

Participation in another clinical trial or concomitant treatment with any investigational product in the 4-week period prior to study entry. 10. Patients with a prior invasive malignancy (except non-melanoma skin cancer) who have had any evidence of disease within the last three years. 11. Major surgery performed or planned within four weeks of the start of study treatment (line placement is not considered major surgery). 12. Patients with serious non-healing wound or ulcer.

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint: Rate of tumor control, defined as confirmed objective response of any duration or PFS-4 [absence of disease progression (clinical and/or radiological)] or death at Week 16 ± 1).
Secondary efficacy endpoints - Progression-free survival rate at six months and one year (PFS-6 and 1-yr PFS), defined as the percentage of patients who are alive and with no evidence of disease progression at six months and one year after the date of randomization (or after the date of registration if only one of the two schedules proceeds to the Expansion stage), respectively. - Rate of response (RR), defined as the percentage of evaluable patients having at least PR or CR. Antitumor activity will be evaluated according to the RECIST, version 1.1, whenever applicable [by helical contrast enhanced computed tomography (CT) scan or magnetic resonance imaging (MRI), as appropriate] a minimum of eight weeks after initial therapy in all patients with measurable disease. - Duration of response (DR), defined as the time between the date when the response criteria (PR or CR, the first that is reached) are fulfilled and the first date when disease progression, recurrence or death is objectively documented (taking the smallest measurements documented since the treatment started as reference for progressive disease). - Progression-free survival (PFS), defined as the time from the date of randomization (or after the date of registration if only one of the two schedules proceeds to the Expansion stage) to the date of negative assessment (progression or death) or last tumor evaluation. - Overall survival (OS), defined as the time from the date of randomization (or after the date of registration if only one of the two schedules proceeds to the Expansion stage) to the date of death (or the last day when the patient is known to be alive), and rate of survival at one year (1-yr OS), defined as the percentage of patients who are alive at one year after the date of randomization (or after the date of registration if only one of the two schedules proceeds to the Expansion stage). |
