Laboratory parameters alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, gamma glutamyl transferase, lactate dehydrogenase, albumin, hemoglobin, protein, amylase, creatine kinase, lipase, basophils, eosinophils, lymphocytes, monocytes, neutrophils, platelets, white blood cells, bicarbonate, chloride, potassium, sodium, bilirubin, blood urea nitrogen, c-reactive protein , calcium, creatinine, direct bilirubin, glucose, magnesium, phosphate, uric acid, hematocrit, partial thromboplastin time , prothrombin time, red blood cells , urine pH, urine specific gravity were assessed to identify systemic AEs.
AEs (all causalities), treatment related AEs and CTCAE severity grades for AEs were reported.
Same participant may be reported in more than 1 CTCAE severity grade.
Categories with at least 1 participant were reported.

Number of Participants With Positive Anti-drug Antibodies (ADA)
Tidsramme: Day 1 up to Day 64
|
Human serum ADA samples of participants who received PF-04950615 (RN316) were analyzed for the presence of anti-PF-04950615 (RN316) antibodies.
Results with titer value >=4.32 nanogram per milliliter of anti-PF-04950615 antibodies were counted as positive.
Number of participants with presence of anti-PF-04950615 antibodies were reported in this outcome measure.
