ListOutcomeTime frameDescription
PrimaryMedian Progression-free Survival (PFS)
Disease was evaluated every 4 cycles on treatment and off treatment every 8-16 weeks until PD or non-protocol therapy start if discontinued for reason other than PD. Participants were observed up to 28.5 months with maximum follow-up of 56.7 months.
Progression-free survival based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) or death. Per RECIST 1.1 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions. Patients who discontinued treatment to pursue potentially curative resection were censored for progression-free survival at the time of surgery. Patients who had not experienced cancer progression or died were censored at their last known follow-up date.
SecondaryMedian Overall Survival (OS)
Participants were followed for survival by clinic visit or telephone every 3 months post-treatment discontinuation up to 36 months from the date that the last participant was enrolled. Median follow-up was 22.9 months with maximum 56.7 months.
OS based on the Kaplan-Meier method is defined as the time from study entry to death or censored at date last known alive. Patients who discontinued treatment to pursue potentially curative resection were censored for progression-free survival at the time of surgery. Patients who had not experienced cancer progression or died were censored at their last known follow-up date.
SecondaryObjective Response RateDisease was evaluated every 4 cycles on treatment. Median (maximum) treatment duration was 7.3 (28.5) months.
The objective response rate (ORR) was defined as the percentage of participants achieving complete response (CR) or partial response (PR) based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.
SecondaryGrade 3-5 Treatment-Related Neutropenia Toxicity RateAEs were evaluated at day 1 of each cycle on treatment and up to 30 days after the last dose. Maximum treatment duration is 28.5 months with median 7.3 months.
The percentage of treated participants experiencing grade 3-5 neutropenia with treatment attribution of possible, probable or definite based on Common Toxicity Criteria for Adverse Events version 4 (CTCAEv4) as reported on case report forms were counted.
SecondaryNumber of Participants With Vitamin D Deficiency at BaselineBaselineVitamin D deficiency was defined as plasma 25-hydroxyvitamin D \[25(OH)D\] level \<20 ng/mL as measured in one batch per established methods by an independent laboratory.
SecondaryVitamin D Sufficiency Rate
Plasma samples were collected at 3 timepoints on treatment: first restaging (cycle 5, day 1), second restaging (cycle 9, day 1) and at treatment discontinuation. Median (maximum) treatment duration was 7.3 (28.5) months.
Percentage of participants that achieve Vitamin D sufficiency defined as plasma 25(OH)D \>=30 ng/mL on treatment as measured in one batch per established methods by an independent laboratory.
SecondaryPlasma 25-hydroxyvitamin D Levels
Plasma samples were collected at 4 timepoints on study: baseline, first restaging (cycle 5, day 1), second restaging (cycle 9, day 1) and at treatment discontinuation. Median (maximum) treatment duration was 7.3 (28.5) months.
Plasma 25-hydroxyvitamin D \[25(OH)D\] levels as measured in one batch per established methods by an independent laboratory.
SecondaryHazard Ratio Between Baseline Plasma 25(OH)D Level and PFSBaseline Plasma 25(OH)D Level and up to 28.5m for evaluation of PFS.
Plasma 25-hydroxyvitamin D \[25(OH)D\] levels as measured in one batch per established methods by an independent laboratory. Plasma 25(OH)D Level is used as continuous data. PFS is estimated based on Kaplan-Meier method (see outcome measure 1). The PFS hazard ratio associated with one unit increase of 25()H)D.
SecondaryHazard Ratio Between Baseline Plasma 25(OH)D Levels and OSBaseline Plasma 25(OH)D Level and up to maximum 56.7 months for evaluation of OS.
Plasma 25-hydroxyvitamin D \[25(OH)D\] levels as measured in one batch per established methods by an independent laboratory. Plasma 25(OH)D Level is used as continuous data.
