The following laboratory parameters were assessed: * Coagulation: Prothrombin time, activated partial thromboplastin time, international normalized ratio, D-dimer, fibrinogen * Hematology: Hemoglobin, hematocrit, red blood cell count, reticulocytes, white blood cell count (with full differentiation), absolute lymphocyte count, platelet count * Clinical chemistry: Na, K, Cl, phosphate, Mg, Ca, albumin, total protein, ALT, AST, bilirubin (direct, total), alkaline phosphatase, lactate dehydrogenase, creatinine clearance, creatinine, glucose (preferably fasting), urea or blood urea nitrogen, cholesterol, triglyceride, CRP, uric acid, amylase, lipase * Urinalysis: pH, glucose, protein, bilirubin, urobilinogen. Microscopic examination: red blood cell count, white blood cell count, epithelial cells, bacteria * Thyroid function: TSH, free triiodothyronine (T3), free thyroxine (T4) * Cardiac function: Cardiac troponin T

This outcome measure presents the overall nanrilkefusp apfa Cmax profile over Cycle 1 Day 1.

The eCRF Hematology data (specifically white blood cell count (WBC)) for each timepoint will be used to derive the Cell counts in 10\^9/L. Once merged with the pharmacodynamic data by subject and timepoint, the following will be used as derivation: • Ki-67+ Cells of CD8+ Cells (10\^9/L) = Ki-67+ Cells of CD8+ Cells (%CD45+) x 0.01 x WBC" Absolute count of Ki-67+ Cells was calculated as percentage of those cells out of CD45+ multiplied by WBC and 0.01.

Based on investigator review of radiographic images according to Response Evaluation Criteria In Solid Tumors for immune-based therapeutics (iRECIST). Objective response rate according to iRECIST was defined as the percentage of participants with complete response according to iRECIST or partial response according to iRECIST for target lesions and assessed by CT/MRI.

Duration of response according to iRECIST was defined as time to disease progression for participants with partial response or complete response according to iRECIST for target lesions and assessed by CT/MRI.

Based on investigator review of radiographic images according to iRECIST. Clinical benefit rate according to iRECIST was defined as the percentage of patients with partial responses, complete responses, and stable disease according to iRECIST for target lesions and assessed by CT/MRI.

Progression-free survival according to iRECIST was defined as the time from the first day of study treatment to the first date of radiological disease progression according to iRECIST or death.
