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
Response Rate
Time Frame: Up to 12 months
Response will be evaluated using the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline.
Up to 12 months
Time to Progression
Time Frame: 24 months
Time to progression (TTP) following bevacizumab integrated with Vigil vaccine in patients failing standard of care in study CL-PTL 105 or in those not otherwise qualifying after vaccine production. This will be measured from the treatment start date (date of first dose) to either the date the patient is first recorded as having disease recurrence (even if the patient went off treatment because of toxicity), or the date of death if the patient dies due to any causes before progression.
24 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
Number of Alive Subjects
Time Frame: 24 months
Survival status of patients after treatment was determined by following these patients up to 24 months.
24 months
Enzyme-Linked ImmunoSorbent Spot (ELISPOT)
Time Frame: Baseline, End of Treatment (30 days after last dose) up to 12 months
To determine if subjects will have a positive (defined as >10 ELISPOTS from baseline) immune response to Vigil. Blood was collected to compare ELISPOT results from baseline until 30 days after last dose.
Baseline, End of Treatment (30 days after last dose) up to 12 months

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. 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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
