Both

Adult T-cell leukemia/lymphoma

[Phase I part]
Patients will receive 5-ALA administered orally once. After administration of 5-ALA, patients will receive OJP-001 once.
Dosage of 5-ALA: 10 mg/kg (1st cohort), 20 mg/kg (2nd cohort), 40 mg/kg (3rd cohort), 60 mg/kg (4th cohort)
[Phase II part]
Patients will receive 5-ALA and OJP-001 once a week for 6 months.
