ListOutcomeTime frameDescription
SecondaryBlood Glucose Levels During Fasting-Mimicking Diet CyclesBaseline and before and after each 4-day FMD cycle, from Cycle 1 through Cycle 8Blood glucose levels measured by participant self-monitoring at baseline and before and after each fasting-mimicking diet (FMD) cycle.
SecondaryAdverse Events Related to the FASTEN InterventionFrom initiation of the FASTEN intervention at Cycle 1 through completion of Cycle 8 of neoadjuvant treatment (treatment cycles generally administered every 21 days; approximately 24 weeks).
Incidence of adverse events related to the FASTEN intervention, as assessed by the investigator and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), Version 5.0.
SecondaryPatient Satisfaction With Fasten Onco
After completion of the third Fasten Onco cycle and at completion of Fasten Onco use following Cycle 8 of neoadjuvant treatment (treatment cycles generally administered every 21 days; approximately 24 weeks).
Patient satisfaction with Fasten Onco assessed using a study-specific 5-point Likert scale ranging from 0 (very dissatisfied) to 4 (very satisfied), with higher scores indicating greater satisfaction.
SecondaryPrognostic Factors for Event-Free SurvivalFrom randomization through study completion, up to 3 years
Assessment of the association between prognostic factors and event-free survival (EFS). Prognostic factors evaluated include age, body mass index (BMI), disease stage, node status, tumor-infiltrating lymphocytes at baseline and surgery, Ki-67 grade and proliferation at baseline and surgery, and other identified prognostic factors.
SecondaryTumor-Infiltrating LymphocytesBaseline and surgery, when availableEvolution of tumor-infiltrating lymphocyte levels during the study, when available.
SecondaryChange From Baseline in Body Mass IndexBaseline through study completion, up to 3 years
Absolute change from baseline in body mass index (BMI), measured in kilograms per square meter (kg/m²), during the study, including changes during and between Fasten Onco active fasting-mimicking diet days.
SecondaryCumulative Administered Dose of Neoadjuvant TreatmentFrom Cycle 1 through Cycle 8; cycles are generally scheduled every 3 weeksTotal administered dose of neoadjuvant treatment received by each participant during the neoadjuvant treatment period.
OtherDose Intensity of Neoadjuvant TreatmentFrom Cycle 1 through Cycle 8; cycles are generally scheduled every 3 weeksDose intensity calculated as the total administered dose as a proportion of the total planned dose.
OtherNumber of Neoadjuvant Treatment Cycles ReceivedFrom Cycle 1 through Cycle 8; cycles are generally scheduled every 3 weeksNumber of neoadjuvant treatment cycles received by each participant.
OtherNumber of Neoadjuvant Treatment Dose DelaysFrom Cycle 1 through Cycle 8; cycles are generally scheduled every 3 weeksNumber of dose delays occurring during neoadjuvant treatment.
OtherNeoadjuvant Treatment DiscontinuationFrom Cycle 1 through Cycle 8; cycles are generally scheduled every 3 weeksNumber of participants who permanently discontinue neoadjuvant treatment before planned completion. Reasons for discontinuation will be recorded.
OtherBlood Ketone Levels During Fasting-Mimicking Diet CyclesBaseline and before and after each 4-day FMD cycle, from Cycle 1 through Cycle 8Blood ketone levels measured by participant self-monitoring at baseline and before and after each fasting-mimicking diet (FMD) cycle.
OtherProportion of Fasting-Mimicking Diet Cycles CompletedFrom Cycle 1 through Cycle 8; each FMD cycle lasts 4 daysProportion of fasting-mimicking diet (FMD) cycles completed relative to the number of neoadjuvant treatment cycles received by each participant.
OtherDuration of Fasten Onco Application UseFrom initiation of Fasten Onco at Cycle 1 through completion of Cycle 8 of neoadjuvant treatment (treatment cycles generally administered every 21 days; approximately 24 weeks).Duration of use of the Fasten Onco application by each participant, measured in days.
OtherTime Spent Using the Fasten Onco ApplicationFrom Cycle 1 through completion of Cycle 8 of neoadjuvant treatment (treatment cycles generally administered every 21 days; approximately 24 weeks).Total time spent using the Fasten Onco application by each participant during the neoadjuvant treatment period, measured in minutes.
OtherAccuracy of Fasten Onco Synchronization With Neoadjuvant TreatmentFrom Cycle 1 through Cycle 8 of neoadjuvant treatment (treatment cycles generally administered every 21 days; approximately 24 weeks).Proportion of Fasten Onco fasting-mimicking diet cycles correctly synchronized with the corresponding neoadjuvant treatment cycles.
OtherInvestigator Satisfaction With Fasten OncoAt completion of Cycle 8 for the last participant at each study center (treatment cycles generally administered every 21 days; approximately 24 weeks after Cycle 1 for that participant).Investigator satisfaction with Fasten Onco assessed using a 5-point Likert scale ranging from 0 (very dissatisfied) to 4 (very satisfied), with higher scores indicating greater satisfaction.
OtherTime Required for Patient Registration in Fasten OncoAt baseline, during initial participant registration in Fasten Onco, before initiation of Cycle 1.Time spent by the oncologist to register a participant in Fasten Onco.
OtherUsability of Fasten Onco Assessed With the French System Usability ScaleAfter completion of the third Fasten Onco cycle (approximately 9 weeks after initiation, if aligned with the 21-day neoadjuvant treatment cycles)
Usability of Fasten Onco assessed using the French version of the System Usability Scale (F-SUS). The F-SUS consists of 10 items and provides a total score ranging from 0 to 100, with higher scores indicating better perceived usability.
OtherPrognostic Factors for Overall SurvivalFrom randomization through study completion, up to 3 years
Assessment of the association between prognostic factors and overall survival (OS). Prognostic factors evaluated include age, body mass index (BMI), disease stage, node status, tumor-infiltrating lymphocytes at baseline and surgery, Ki-67 grade and proliferation at baseline and surgery, and other identified prognostic factors.
