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.

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
Assess the safety and tolerability of CT-0508 by estimating the frequency and severity of adverse events in subjects with HER2 overexpressing solid tumors.
Time Frame: 14 months
Frequency and severity of adverse events including, but not limited to, estimating frequency and severity of Cytokine Release Syndrome (CRS)
14 months
Assess the feasibility of manufacturing CT-0508 by describing the percentage of products passing release criteria.
Time Frame: 12 months
Percentage of products that pass release criteria among all manufactured products.
12 months
Assess the safety and tolerability of CT-0508 in combination with pembrolizumab by estimating the frequency and severity of adverse events in subjects with HER2 overexpressing solid tumors (CT-0508 and pembrolizumab substudy only)
Time Frame: 14 months
Frequency and severity of adverse events including, but not limited to, estimating frequency and severity of Cytokine Release Syndrome (CRS)
14 months

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
Estimate the objective response rate (ORR), according to RECIST v1.1, of at least 1 dose of CT-0508 among subjects with HER2 overexpressing solid tumors.
Time Frame: 24 months
Proportion of subjects with an objective response (either a complete response [CR] or partial response [PR]) in subjects who received at least 1 dose of CT-0508 and at least the 8-week tumor evaluation as determined by the investigator using RECIST v1.1.
24 months
Estimate progression-free survival (PFS).
Time Frame: 24 months

Defined as the time between the date of first dose and the date of first documented disease progression as determined by the investigator using RECIST v1.1 or death due to any cause, whichever occurs first.

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.
