About

The purpose of this study is to determine whether TBI-1401(HF10), a spontaneously attenuated mutant of Herpes Simplex Virus Type 1 (HSV-1), is safe and tolerable in the treatment of solid tumors with superficial lesions.

Full description

This is an open label, non-randomized, dose escalation Phase I study evaluating the repeated intratumoral administrations of the TBI-1401(HF10), a spontaneously attenuated mutant of HSV-1, in patients with solid tumors with superficial lesions (e.g., malignant melanoma and squamous cell carcinoma of the skin).

The study will evaluate the safety and tolerability of repeated intratumoral administrations of TBI-1401(HF10) at dose levels of 1 x 10^6 TCID50/dose (cohort 1) and 1 x 10^7 TCID50/dose (cohort 2) in Japanese patients. Three patients will be enrolled in each cohort. Patients in the each cohort will receive a total of four intratumoral administrations in the same lesion.

Patients must have passed 4 weeks after the completion of prior therapy [except bone metastasis therapy], or passed 8 weeks if immuno checkpoint inhibitor was treated.
Patients must be able to understand and willing to sign a written informed consent document.

Exclusion criteria

Patients with Grade ≥ 2 pre-existing neurologic abnormalities (CTCAE version 4.0).
Patients with severe cardiac disorder or abnormal cardiac rhythm.
Patients with psychiatric disorder or drug dependency which affects informed consent.
Pregnant or breastfeeding women; women or men, having normal reproductive potential, who disagree with the protection of pregnancy within the timeframe of the study.
Patients received any other investigational products within 4 weeks, or within 8 weeks if immuno checkpoint inhibitor was treated.
Patients would limit compliance with study requirements, as determined by the investigator.
