Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence, nature, and severity of Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs).
Time Frame: Through study completion, an average of 1 year
Adverse events with the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0 used as a guide for the grading of severity.
Through study completion, an average of 1 year
Estimate of Maximum Tolerate Dose (MTD)
Time Frame: Up to 3 weeks
MTD will be estimated based on Dose limiting toxicity (DLT) observed during the first 3 weeks of treatment
Up to 3 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Plasma Concentration of ONO-4685
Time Frame: Up to 48 weeks
Plasma concentration will be assessed to evaluate Pharmacokinetics
Up to 48 weeks
Plasma Concentration of Anti-Drug Antibody (ADA)
Time Frame: Up to 48 weeks
ADA to ONO-4685 will be assessed to evaluate potential immunogenicity.
Up to 48 weeks
Antitumor Activity of ONO-4685
Time Frame: Through study completion, an average of 1 year
Antitumor Activity of ONO-4685 will be assessed according to the response criteria for Lymphoma.
Through study completion, an average of 1 year

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
