Figure Lengend Snippet: Figure 10. TNG462 treatment drives dose-dependent and durable PD activity in the LU99 MTAP-null NSCLC xenograft model. PK/PD analysis of TNG462 following compound treatment for 7-days. (A) PRMT5 activity by quantification of a single SDMA-modified protein substrate and free TNG462 plasma concentrations were determined at the indicated time points postlast dose. N = 4 tumors/time point/dose level. Data are presented as mean ± SEM for the PD analyses. (B) SDMA-modified protein levels in tumors collected at the indicated time points postlast dose. TNG908 was dosed at 120 mg/kg BID and TNG462 was dosed at 30 mg/kg BID for 7-days. N = 4 tumors/time point/treatment. Data are presented as mean ± SEM. (C) Cellular thermostability assay where the LN18 MTAP-null cancer cell line was treated with TNG462 at the indicated concentrations and treatment conditions.
