Study start date: September 25, 2017

Actual date on which the first participant was enrolled.

A Phase I, open-label, multi-center study to determine the recommended dose of TBI-1401(HF10) treatment in combination with chemotherapy (Gemcitabine + Nab-paclitaxel or TS-1) in patients with stage III or IV unresectable pancreatic cancer. Patients with stage IV must failed a gemcitabine based first-line chemotherapy. Patients with stage III will receive the repeated intratumoral injection of TBI-1401(HF10) at recommended dose at 2-week intervals in combination with intravenous infusion of 1000 mg/m\^2 Gemcitabine and 125 mg/m\^2 Nab-paclitaxel at weekly for 3 weeks followed by 1 week rest. Patients with stage IV will receive the repeated intratumoral injection of TBI-1401(HF10) at recommended dose at 2-week intervals in combination with oral of 40 - 60 mg TS-1 at twice daily for 4 weeks followed by 2 weeks rest. Patients will receive the combination therapy of TBI-1401(HF10) + chemo for up to 1 year if eligible for treatment.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

36 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

9 inclusion criteria required to participate

Patients with histologically or cytologically confirmed unresectable pancreatic cancer (stage III or IV) based on the General Rules for the Study of Pancreatic Cancer (The 7th edition), and never received anti-cancer therapy (radiation therapy, chemotherapy, immunotherapy, surgery, clinical trials).

Patients with primary lesion will be intratumorally injectable for TBI-1401(HF10) by EUS (endoscopic ultrasound).

Patients must be ≧20 years of age.

Patients must have at least one measurable lesion evaluated by Computed Tomography (CT) scan on RECIST ver.1.1 at pre-treatment.

9 exclusion criteria prevent from participating

Patients receiving anti-herpes medication within 1 week prior to TBI-1401(HF10) treatment (except local treatment such as ointment).

Patients with a significant tumor bleeding or coagulation abnormality that could not treat intratumoral injection or biopsy in safe.

Patients with clinically evident Hepatitis B surface antigen (HBs) positive, Hepatitis C virus (HCV) antibody positive and HSV-RNA positive, Human Immunodeficiency Virus (HIV) antibody positive.

Patients with the active symptom of Epstein-Barr virus (EBV) infection.

Treatment Groups

Group I

Experimental

1x10\^6 or 1x10\^7 TCID50/mL TBI-1401(HF10) administered to the tumor in a total volume up to 2.0 mL (injection volume will be adjusted based on the tumor size) by EUS-guided intratumoral injection and 1000 mg/m\^2 Gemcitabine and 125 mg/m\^2 Nab-paclitaxel injected by intravenous infusions.

Group II

Experimental

1x10\^6 or 1x10\^7 TCID50/mL TBI-1401(HF10) administered to the primary tumor in a total volume up to 2.0 mL (injection volume will be adjusted based on the tumor size) by EUS-guided intratumoral injection and hepatic metastasis in a total volume up to 2.0 mL (injection volume will be adjusted based on the tumor size) by EUS-guided intratumoral injection or percutaneous injection and TS-1 administered by oral.
