DS-3201b is an experimental drug. It is not approved for regular use. It can only be used in clinical research.
Adults with non-Hodgkin lymphoma (NHL) might be able to join this study if their disease:
- has come back after remission
- is not responding to current treatment
This study has three parts:
- Dose Escalation is to find the safe dose of DS-3201b that adults with advanced NHL can tolerate.
-
Dose Expansion is to:
- find out how effective DS-3201b is for rare types of NHL
- collect additional safety data
- Drug-Drug Interaction (DDI) Cohort (US Only) is to evaluate the effect of DS-3201b on the pharmacokinetics (PK) midazolam and digoxin when co-administered to patients with NHL

- Best overall response, based on international consensus criteria [ Time Frame: from the start of study treatment to the end of follow-up visit (within 5 years) ]
Best overall response is defined as the percentage of participants who achieved each category as the best response, considering all overall responses assessed at all time points after the start of study treatment.
Categories: CR, CRu, PR, SD, RD/PD, UA
Categories: Malignant lymphoma, ATL, CTCL
- Objective response rate (ORR) [ Time Frame: within 5 years ]ORR is defined as the percentage of participants who were assessed for best overall response, who achieved CR, UCR, or PR

- Duration of response (DOR) [ Time Frame: within 5 years ]DOR is defined as the time from the date at which criteria are first met for CR or PR (including CRu for ATL) until the first date that progressive disease is objectively documented.
- Progression-free survival (PFS) [ Time Frame: witihn 5 years ]PFS is defined as the time from the date of the first dose to the earlier of the dates of the first objective documentation of disease progression or death due to any cause.
- Number of participants with malignant lymphoma who achieved each level of therapeutic response per international consensus standards [ Time Frame: through the end of the study (within approximately 5 years) ]Categories: Complete remission (CR), Partial remission (PR), Stable disease (SD), Relapsed disease or progressive disease (RD/PD)
- Number of participants with ATL who achieved each level of therapeutic response per international consensus standards [ Time Frame: through the end of the study (within approximately 5 years) ]Categories: CR, Uncertified complete remission (CRu), PR, SD, RD/PD, Unassessable (UA)
- Number of participants with CTCL who achieved response per 2011 CTCL criteria [ Time Frame: through the end of the study (within approximately 5 years) ]Categories: CR,PR,SD,PD,Relapse
