A Study of Avelumab in Combination With Axitinib In Non-Small Cell Lung Cancer (NSCLC) or Urothelial Cancer (Javelin Medley VEGF)

An Adverse Event (AE) was any untoward medical occurrence attributed to study drug in a participant who received avelumab or axitinib. Treatment-emergent adverse events (TEAEs) were those events with onset dates occurring during the on-treatment period (the time from the first dose of study treatment through minimum 30 days post last dose of study treatment or start day of new anti-cancer treatment -1 day).

The following hematology parameters were assessed: anemia, hemoglobin increased, international normalized ratio (INR) increased, lymphocyte count decreased, lymphocyte count increased, neutrophil count decreased, platelet count decreased and white blood cell decreased. Laboratory abnormality events were graded according to NCI CTCAE v 4.03 (grade 3= severe and grade 4= life-threatening). Categories with non-zero values are presented.

The following chemistry parameters were assessed: alanine aminotransferase increased, alkaline phosphatase increased, aspartate aminotransferase increased, blood bilirubin increased, cholesterol high, creatine phosphokinase (CPK) increased, creatinine increased, gamma-glutamyl transferase (GGT) increased, hypercalcemia, hyperglycemia, hyperkalemia, hypermagnesemia, hypernatremia, hypertriglyceridemia, hypoalbuminemia, hypocalcemia, hypoglycemia, hypokalemia, hypomagnesemia, hyponatremia, hypophosphatemia, lipase increased and serum amylase increased. Laboratory abnormalities were graded according CTCAE version 4.03 (grade 3= severe, grade 4= life-threatening and grade 5= death related). Categories with non-zero values are presented.

TTR was defined as the time from the first dose of study treatment to the first documentation of objective tumor response documented in participants with confirmed objective response (CR or PR). CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis <10 mm). No new lesions. PR was defined as >=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. Analysis was performed using Kaplan-Meier method.

Duration of response was defined as the time from the first documentation of objective tumor response to the first documentation of objective tumor progression or to death due to any cause, whichever occurred first in participants with confirmed objective response (CR or PR). CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis <10 mm). No new lesions. PR was defined as >=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. Analysis was performed using Kaplan-Meier method.

PFS was defined as the time from first dose of study treatment (ie, start date) to the date of progression of disease (PD) by RECIST v 1.1 or death due to any cause, whichever occurred first. PFS data was censored on the date of the last adequate tumor assessment for participants without an event (PD or death), for participants who started new anti-cancer treatment prior to an event, or for participants with an event after two or more missing tumor assessments. PD as per RECIST v1.1 for target lesions was defined as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed (over baseline if no decrease in the sum is observed during therapy), with a minimum absolute increase of 5 mm. For non-target lesions PD was defined as unequivocal progression of pre-existing lesions. Analysis was performed using Kaplan-Meier method.

Overall survival was defined as the time from the date of first study treatment to the date of death due to any cause. Participants last known to be alive were censored at date of last contact. Analysis was performed using Kaplan-Meier method.

PD-L1 status was defined as positive when PD-L1 staining of any intensity was observed in >= 1% of the tumor cells. PD-L1 status was defined as negative when PD-L1 staining of any intensity was observed in < 1% of the tumor cells.

Mutational load within tumor tissue was defined as number per megabase of the genome, coding, base substitution, and indel mutations present in the sample. Mutational load was determined in whole blood samples using next generation deoxyribonucleic acid (DNA) sequencing followed by computational analysis.

The immune response was measured by total T cell receptor (TCR) sequencing in peripheral blood and determined the characterization of immune repertoires. Fraction productive of cells is defined as the number of T cells within the total nucleated cell count (T cells and non-T cells).

The immune response was measured by TCR sequencing in peripheral blood and determined the characterization of immune repertoires. Simpson clonality is calculated for a sample as the square root of Simpson's diversity index for all productive rearrangements. Values for clonality ranged from 0 to 1. Values near 1 represented samples with one or a few predominant rearrangements (monoclonal or oligoclonal samples) dominating the observed repertoire. Clonality values near 0 represented more polyclonal samples.

The immune response was measured by total TCR sequencing in peripheral blood and determined the characterization of immune repertoires.

ADA and nAb positive was defined as presence of at least one positive ADA and nAb sample, respectively. NAb analysis was planned to be conducted for ADA positive samples.
