Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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)

  2. 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.

  3. 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)


Secondary Outcome Measures :
  1. 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.

  2. 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.

    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.
