About

Primary Objectives

• In phase 1b cohort, to determine MTD (maximum tolerated dose) of nal-IRI (ONIVYDE®) in combination with Ramucirumab (Cyramza®) and TAS-102 (LONSURF®)
• In phase II cohort, to evaluate disease objective response rate (ORR) of Ramucirumab (Cyramza®), nal-IRI (ONIVYDE®) in combination with TAS-102 (LONSURF®) Secondary Objectives
• To evaluate disease control rate (DCR)
• To evaluate progression-free survival (PFS)
• To evaluate overall survival (OS)
• To assess the safety profile
• To study the blood biomarkers

Full description

• Eligible patients will be treated with infusional nal-IRI (ONIVYDE®, free form) 50/60/70 mg/m2 over 90 minutes day 1, Ramucirumab 8 mg/kg over 60 minutes day 1, in combination with oral TAS-102 (LONSURF®) 30 mg/m2/b.i.d. day 1-5, every 14 days.
• Every 14 days count as one cycle.
• Patients will be treated until disease progression, unacceptable toxicity or other condition meeting the off-study criteria.
• Scheme of phase 1b: dose Level 0 to 2 will be tested with the following dose levels:
• Dose level 0= Ramucirumab(Cyramza®) 8mg/kg on day 1, nal-IRI (ONIVYDE®, free form) 50 mg/m2 on day 1 plus Trifluridine/Tipiracil (Lonsurf®) 30mg/m2 on day 1-5, q2wk
• Dose level 1= Ramucirumab(Cyramza®) 8mg/kg on day 1, nal-IRI (ONIVYDE®, free form) 60 mg/m2 on day 1 plus Trifluridine/Tipiracil (Lonsurf®) 30mg/m2 on day 1-5, q2wk
• Dose level 2= Ramucirumab(Cyramza®) 8mg/kg on day 1, nal-IRI (ONIVYDE®, free form) 70 mg/m2 on day 1 plus Trifluridine/Tipiracil (Lonsurf®) 30mg/m2 on day 1-5, q2wk
• Adaptive phase IB cohort:
• 3+3 dose escalation will be applied for phase Ib cohort. All treated patients of MTD dose level in phase 1b cohort will be incorporated into phase II cohort for final analysis. No intra-patient dose escalation is allowed during DLT period. Patients could only have dose modification after the DLT period. G-CSF prophylaxis is not allowed in DLT period.
• Dose escalation rule: Two to six patients will be enrolled in each cohort depending on cases with DLTs. The starting dose is dose level 0. If none of the first 3 patients experiences DLT, then dose escalation will proceed to the next cohort of patients. If only 1 of 3 patients developed DLT, the cohort will be expanded to 6 patients. If more than 1 patient developed DLT at a certain dose level/group, the dose level/group is considered intolerable to the patients. If no more than 1 out of 6 patients experience DLT, the dose level/group is considered tolerable. A minimum of 6 evaluable patients will be treated at the MTD. The MTD at which no more than 1 of the 6 patients experience DLT will be determined for the phase II cohort. Based on results from phase IB cohort, MTD will be determined. All treated population in MTD cohort will be incorporated into phase II cohort for final analysis.
