Note: The criteria for grade 4 hypoalbuminemia and anemia are not a numeric parameter and therefore are omitted.

*

Baseline alkaline phosphatase was used to assess if patient values were within normal limits (WNL) or elevated at baseline to determine treatment CTCAE grades [at baseline, 101 patients (60.1%) were WNL, 67 patients (40.0%) were elevated].

Baseline bilirubin (Bili) was used to assess if patient values were WNL or elevated at baseline to determine treatment CTCAE grades [at baseline, 148 patients (93.1%) were WNL, 11 patients (6.9%) were elevated].

Chromogranin A values were determined to be WNL or elevated. At baseline, 73 patients (72.3%) had elevated chromogranin A. During treatment, 198 administrations (74.4%) led to elevated chromogranin A.
