berzosertib (M6620)

Molecular docking identified YM-201636 and VE-822 (Berzosertib) as potential drugs targeting CDKN2A, both showing promise for LUAD treatment in vivo. PASEs constitute a comprehensive biomarker for predicting prognosis and monitoring the TIME in LUAD patients. Specifically, CDKN2A stands out as a potential prognostic biomarker and drug target for LUAD.

This novel combination of ATR inhibitor berzosertib with irinotecan did not lead to objective responses in patients with TP53-mutated, advanced gastroesophageal adenocarcinoma. The combination regimen was well tolerated without unexpected adverse events. This trial was registered with ClinicalTrials.gov (NCT03641313).

Berzosertib 270 mg/m2 and irinotecan 180 mg/m2 was the RP2D. The combination is associated with manageable side effects and promising disease activity in ATM mutant solid tumors.

We used AZD0156, an ATM inhibitor, and VE-822, an ATR inhibitor, in combination with normo-fractionated RT to treat two HPV-positive and two HPV-negative HNSCC cell lines. In co-culture with NK cells, an upregulation of activation markers on NK cells was observed, particularly after contact with RT + ATMi-treated HPV-negative HNSCC cells. We conclude that ATM inhibitor-related induction of senescence in HNSCC cells shapes the tumor micro-environment in way that NK cell phenotype is changed.

The present study developed a PRS using 101 machine learning combination algorithms, which could aid in risk stratification and prognosis for LUAD patients. The candidate drugs and target may provide new insights in the treatment of high PRS group patients.

Here, we demonstrate a remarkable potency of the PARPi talazoparib in HRD PDAC. Substituting olaparib, currently the only approved inhibitor in PDAC, with talazoparib in our PAD regimen enhanced its efficacy while maintaining comparable tolerability in vivo. Importantly, we show that PAD is an effective therapeutic regimen that can be extended to the most prevalent HR-defective genotypes in PDAC including ATM, BRCA1, BRCA2 and PALB2 in a preclinical setting. Collectively, these data provide a strong rationale to implement the refined regimen, talazoparib-based PAD, as a therapeutic concept tailored for HRD PDAC patients.

FUT8 is a crucial gene that causes colon cancer and is linked to tumour immunity. VE-822 is a promising candidate for treating CRC by targeting FUT8.

This combination shows antitumor activity, including in patients with and without homologous recombination-compromised tumors and those previously treated with platinum. Adding berzosertib further increases the DDR response elicited by combination cisplatin/veliparib treatment in BRCA-wildtype patients, indicating increased replication stress at the RP2D/MTD.

Drug sensitivity analysis revealed heightened sensitivity to cyclophosphamide, Sinularin, Wee1 inhibitor, osimertinib, JQ1, VE-822, and AZD6738 in high-risk patients. Furthermore, CCK-8 assays and Wright-Giemsa staining confirmed the crucial role of PARP1 in regulating MM cell viability. This PANoptosis-based prognostic model provides a valuable tool for predicting MM prognosis and guiding personalized treatment.

This study highlights the potential of combining lurbinectedin with ATR inhibitors in STS treatment and validates SLFN11 as a predictive biomarker for this combination therapy. These findings support further clinical evaluation of this therapeutic strategy in STS patients.
