Phosphorylated S6RP is a biomarker for inhibition of the mammalian target of rapamycin complex 1 (mTORC1). Phosphorylated S6RP was measured in stimulated B cells via flow cytometry. The raw measurements were expressed as median fluorescence intensity (MFI). MFI values were normalized against calibration beads using a linear regression transformation carried out on a log-log scale and reported as equivalent reference fluorophores (ERF). The biomarker evaluable population included all subjects who took at least one dose of study drug and had at least one non-missing pharmacodynamic (PD) assessment. Results were not available for the single subject treated in the 7.5-mg dose group and for one of the two subjects treated in the 15-mg dose group.

Tumor tissue biopsies were performed at Baseline and on Day 15 3 hours post dose. Levels of pS6RP were quantified using immunohistochemical (IHC) methods.

Tumor response was based on Investigator assessment according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 for solid tumors (NSCLC, HCC, NET, and HRPBC), and the International Working Group Criteria (IWC) for DLBCL. Overall Response Rate is defined as the percentage of participants with a best overall response of complete response or partial response. Complete response is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. In Part A, participants with MM and participants with GBM were not evaluated for tumor response.
