The results revealed that APG-1387 improved the antitumor activity of olaparib in 4 out of 6 (67%) BRCA1/2 mutant PDXs with a 44% reduction of T/C (%) value (T, treatment group, C, vehicle control), including one partial tumor regression (PR)….In summary, our results suggest that APG-1387 is a potential agent for pancreatic cancer treatment, ascribing to its potential synergistic antitumor effect by combining with either PARP inhibitors in BRCA1/2 mutant or MEK inhibitors in KRAS mutant pancreatic cancers.
