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 of adverse events as defined as DLTs
Time Frame: 28 days
Dose limiting toxicity (DLT) is defined as protocol-defined adverse events that occur within 28 days following infusion of Neo-TCR-P1 administered as a single agent without or with IL-2, or in combination with nivolumab.
28 days
Number of participants with adverse events as a measure of safety and tolerability of NeoTCR-P1 or NeoTCR-P1 in combination with nivolumab
Time Frame: 2 years
Toxicity will be classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, version 5.0). Cytokine release syndrome (CRS) and neurotoxicity associated with NeoTCR-P1 will be graded according to ASBMT consensus grading.
2 years
Maximum Tolerated Dose (MTD) of NeoTCR-P1
Time Frame: 2 years
The MTD is defined as the highest dose with an observed incidence of DLT in no more than one out of six patients treated at a particular dose level.
2 years
Feasibility of manufacturing NeoTCR-P1
Time Frame: 2 years
Percent of screened patients that enroll on study and receive NeoTCR-P1
2 years

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
Maximum concentration of NeoTCR-P1 (Cmax) in the peripheral blood
Time Frame: 2 years
2 years
Area-under-the-concentration-vs-time-curve (AUC) in the peripheral blood
Time Frame: 28 days
28 days
Persistence of NeoTCR-P1 in samples of peripheral blood
Time Frame: 2 years
2 years
Objective Response Rate (ORR) in participants with solid tumors following infusion of NeoTCR-P1 as a single agent or in combination with nivolumab
Time Frame: 2 years
ORR will be defined as Complete Response (CR) or Partial Response (PR) per RECIST v1.1, as determined by the investigator
2 years
Duration of Response mediated by neoTCR-P1 administered as a single agent or in combination with nivolumab to participants with solid tumors
Time Frame: 2 years
Duration of response, defined as time from the first occurrence of a documented objective response to the time of relapse or death from any cause
2 years
Progression free survival (PFS) in participants with solid tumors following infusion of NeoTCR-P1 as a single agent or in combination with nivolumab
Time Frame: 2 years
PFS is defined from date of administration of NeoTCR-P1 cell infusion to the date of disease progression per the RECIST v1.1 or death as a result of any cause. Subjects who do not meet criteria for progression by the analysis data cut-off date will be censored at their last evaluable disease assessment date
2 years
Overall survival (OS) in participants with solid tumors following infusion of NeoTCR-P1 as a single agent or in combination with nivolumab
Time Frame: 2 years
OS will be measured from the date of administration of NeoTCR-P1 to the date of death. Subjects who have not died by the analysis data cut-off date will be censored at their last date of contact.
