简要总结
The purpose of this study is to determine if TBI-1401(HF10) in combination with ipilimumab is effective in Japanese patients with stages IIIB, IIIC, or IV unresectable or metastatic melanoma.
详细描述
The study is designed to assess efficacy and safety with repeated administration of intratumoral injections of TBI-1401(HF10) at 1x10^7 TCID50/mL in combination with intravenous infusions of 3mg/kg ipilimumab in Japanese patients.
This is a single arm, open label Phase II study, to evaluate the efficacy and safety of TBI-1401(HF10) treatment in combination with the immunologic checkpoint inhibitor, ipilimumab (anti-CTLA-4 monoclonal antibody). The study population will include patients with Stage IIIB, IIIC or IV unresectable or metastatic malignant melanoma who are ipilimumab-eligible.
Patients will receive the dose of 1x10^7 TCID50/mL TBI-1401(HF10) (for a total of 6 injections; the first 4 injections at 1-week intervals; the remaining 2 injections at 3-week intervals) + ipilimumab at 3 mg/kg (for a total of 4 intravenous infusions, each administered at 3-week intervals).
Following combination therapy, patients may continue to receive the 1x10^7 TCID50/mL TBI-1401(HF10) alone for up to an additional 13 injections (total of 19 injections = 1 year) if they have tolerated the study treatment, are responding, have stable disease, or have progressive disease that is not clinically significant in the judgment of the Investigator.

排除标准
- •Patients who were previously treated with ipilimumab by intravenous infusion.
- •Patients receiving chemotherapy or molecularly targeted drug or anti-PD-1 antibody treatment or radiotherapy or immunotherapy within 4 weeks prior to initiating study treatment.
- •Patients with a history of Grade 4 adverse events caused by chemotherapy, molecularly targeted drug, anti-PD-1 antibody treatment, radiotherapy or immunotherapy conducted more than 4 weeks prior to TBI-1401(HF10) treatment, or presence of such adverse events of Grade 2 or greater, except alopecia and adverse events controlled by a treatment.
