Study Overview

Status

Status

Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: dose escalation then expansion

Dose escalation of this study will follow a 3+3 study design with a starting intravenous (IV) dose of 0.1 mg/kg. Six dose levels are planned: level 1,0.1 mg/kg; level 2,0.3 mg/kg; level 3, 1.0 mg/kg; level 4,3.0 mg/kg; level 5,10 mg/kg; level 6,20 mg/kg.

Dose Expansion - Up to 20 subjects will be enrolled and treated at the dose determined in Dose Escalation arm.
Drug: DS-8895a

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
number of participants experiencing dose limiting toxicities
Time Frame: day 1 through day 28
to investigate the safety of DS-8895a reporting on frequency and seriousness of treatment emergent adverse events
day 1 through day 28
number of participants experiencing clinical or laboratory adverse events
Time Frame: from start of treatment to end of treatment, on expected average 12 weeks
to investigate the safety of DS-8895a reporting on frequency and seriousness of treatment emergent adverse events
from start of treatment to end of treatment, on expected average 12 weeks
serum pharmacokinetics of DS-8895a
Time Frame: Cycle 1 - days 1, 2, 4, 8 and 15; Cycle 2-days 1, 2, 4, 8 and 15; Cycle 3 and on- days 1; end of study; 45 days post last dose
pharmacokinetics (Area Under the Curve-AUC, Terminal Elimination half-life-t1/2, Total Body Clearance) of DS-8895a in Japanese subjects with advanced solid tumors, and also to investigate the recommended dose of DS-8895a for subsequent clinical studies

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

Primary Completion (Actual)

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.

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.
