Study Details

Study Description

Brief Summary

The main purpose of this study is to see whether the combination of selinexor (KPT-330) and irinotecan can help people with esophageal or stomach cancer. Researchers also want to find out if the combination of selinexor (KPT-330) and irinotecan is safe and tolerable.

Condition or Disease	Intervention/Treatment	Phase
Esophageal Cancer Gastric Cancer	Drug: Selinexor Drug: Irinotecan	Phase 1

Detailed Description

This is an open label, single group, non-randomized, phase I study with cohort expansion that utilizes the standard 3+3 design for dose. The dose of selinexor will be escalated in combination with the standard doses of irinotecan. The maximum tolerated dose (MTD) for study is defined as the highest dose level at which 1 or less of 6 patients experience a dose limiting toxicity DLT.

Once the MTD is reached and/or the recommended dose for expansion is determined, an additional cohort of 15 patients with advanced gastric or esophageal cancer will be accrued to better define the safety and tolerability of the combination regimen.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Selinexor in Combination with Irinotecan The first study drug is called selinexor (KPT-330). This drug is taken by mouth on days 1, 3, 8 and 10 of each cycle. The starting dose of selinexor will be dependent on the cohort in which the patient is enrolled into. Level -1: 25 mg/m^2; Level 1: 40 mg/m^2; Level 2: 50 mg/m^2; Level 3: 65 mg/m^2. The second drug is called irinotecan. This drug is given as intravenous (IV) infusion on days 1 and 8 of each cycle. Participants will receive the standard recommended dose: 125 mg/m^2.	Drug: Selinexor Selinexor is a potent slowly reversible covalent Selective Inhibitor of Nuclear Export (SINE) that specifically blocks the karyopherin protein Exportin 1 or XPO1. Other Names: KPT-330 Drug: Irinotecan Irinotecan is a topoisomerase inhibitor and is approved by FDA to treat colorectal cancer. It is administered intravenously. Other Names: Camptosar

Outcome Measures

Primary Outcome Measures

Maximum Tolerated Dose (MTD) [Up to 18 months]
The MTD for study is defined as the highest dose level at which 1 or less of 6 patients experience a dose limiting toxicity (DLT).

Secondary Outcome Measures

Progression Free Survival (PFS) [Up to 18 months]
PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Progression will be evaluated using the new international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).
Objective Response Rate (ORR) [Up to 18 months]
Only those participants who have measurable disease present at baseline, have received at least one cycle of therapy, and have had their disease re-evaluated will be considered evaluable for response. Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short axis). Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
Best Overall Response [Up to 18 months]
The best overall response is the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Response will be evaluated using RECIST guideline V 1.1. Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria.
Overall Survival (OS) [Up to 18 months]
Overall Survival is defined as the time period from start of treatment to death.
