RESULTS 100% of the 15 PDX tumors exhibited significant growth inhibition either in response to KRT-232 alone or in combination with BRAF and/or MEK inhibitors. Only BRAFV600wt tumors responded to KRT-232 treatment alone while BRAFV600E/M PDXs exhibited a synergistic response to the combination of KRT-232 and BRAF/MEK inhibitors. CONCLUSIONS KRT-232 is an effective therapy for the treatment of either BRAFwt or PANwt (BRAFwt, NRASwt) TP53WT melanomas. In combination with BRAF and/or MEK inhibitors, KRT-232 may an effective treatment strategy for BRAFV600 mutant tumors.

Data were presented on PARPi efficacy in prostate cancers with alterations in other DNA damage repair genes which suggest low response rates in ATM-, CHEK2-, CDK12-altered tumors and promising results in PALB2-, RAD51B-, FANCA-, and BRIP1-altered tumors.

Tumor microenvironment (TME), comprising of immune cells and cancer-associated fibroblasts, plays a key role in driving poor prognosis and resistance to chemotherapy. Herein, we aimed to identify a TME-associated, risk-stratification gene biomarker signature in PDAC. EXPERIMENTAL DESIGN The initial biomarker discovery was performed in The Cancer Genome Atlas (TCGA, n=163) transcriptomic data. This was followed by independent validation of the gene signature in The International Cancer Genome Consortium (ICGC, n=95), E-MTAB-6134 (n=288), and GSE71729 (n=123) datasets for predicting overall survival (OS), and for its ability to detect poor molecular subtypes. Clinical validation and nomogram establishmen
