Efficacy of ATR kinase inhibitor elimusertib monotherapy or combination in tumors with DNA damage response pathway and other genomic alterations. (PubMed, Mol Cancer Ther) - "The combination of the PI3K inhibitor copanlisib with elimusertib enhanced EFS-2 compared to monotherapy in 3 of 11 models tested. The combination of elimusertib with the poly (ADP-ribose) polymerase (PARP) inhibitor niraparib enhanced antitumor activity compared to single agents in PARP-resistant PDX models. Our study shows that ATR inhibition has antitumor activity, including in models with both intrinsic and acquired PARP inhibitor resistance. Further work is needed to better refine patient selection for ATR-based therapies."

CDK9 pharmacological inhibition has antitumor activity in marginal zone lymphoma models and can improve the effects of BTK, PI3K, and BCL2 inhibitors (AACR 2025) - P1 | "PRT2527 has shown favorable tolerability, with manageable toxicity in a phase 1 study for solid tumor patients (Patel et al, ENA 2023), and it is now in phase 1 as a single agent and in combination with the BTK inhibitor zanubrutinib for hematological cancers patients (NCT05665530)...The combination of PRT2527 with the PI3K inhibitor idelalisib, with the BTK inhibitor ibrutinib, or triple combination with the PI3K inhibitor copanlisib and the BCL2 inhibitor venetoclax was beneficial in all parental cells, and the benefit was maintained, although reduced, in derivatives with acquired resistance to PI3K and BTK inhibitors. CDK9 inhibition with PRT2527 has in vitro antitumor activity in MZL models, which is maintained in models with acquired resistance to PI3K, BTK, or BCL2 inhibitors. CDK9 inhibition with PRT2527 can improve the sensitivity of MZL cells to BTK, PI3K, and BCL2 inhibitors."

A chemoradiation platform for evaluating multimodal therapy effects on tumor viability and invasion ex vivo (AACR 2025) - "Proof-of-concept experiments with HPV-negative HNSCC lines (HN30 and HN31, established from primary and metastatic disease from the same patient) and HPV-positive HNSCC cells (SCC154) revealed that treatment with cetuximab and ibrutinib enhances radiosensitivity in HN31 cells. The PI3K inhibitor copanlisib radio-sensitized both HN30 and HN31, while alpelisib sensitized SCC154 cells. Additionally, copanlisib, afatinib, and ibrutinib were shown to limit ECM invasion of HN31, while the AKT inhibitor ipatasertib and the mTOR-targeting rapamycin promote invasion of HN30 cells, as observed in previous studies (Brolih et al., 2018). Our pilot experiments using bioprinted patient-derived HNSCC organoids confirmed the feasibility of performing sensitivity screening by integrating bioprinting, conventional viability assays, and advanced image analysis techniques. Our goal is to establish a personalized therapeutic pipeline for patients with advanced HNSCC, maximizing responses to..."

Profiling protein-protein interactions to predict sensitivity to drugs targeting BCL2 family members in lymphoma models (AACR 2025) - "Drug sensitivity parameters were integrated with protein data using Spearman Correlation and Multiple Linear Regression (MLR, Lasso). We exposed MCL (n=10, JVM2, REC1, JEKO1, UPN1, SP49, SP53, MAVER1, GRANTA519, Z138, MINO), MZL (n=6, VL51, SSK41, Karpas1718, HC1, HAIRM, ESKOL) cell lines and MZL models of secondary resistance (MZL-RES) to idelalisib (n=2), copanlisib (n=2), ibrutinib (n=2), venetoclax (n=1) and copanlisib/venetoclax (n=2), to BCL2i (venetoclax, sonrotoclax), BCL2/BCXLi (navitoclax), and MCL1i (S63845). Anti-apoptotic inhibitors show variable heterogeneous activity in MCL and MZL models, including those resistant to PI3Ki and BTKi, which could be predicted quantifying the BCL2-family members levels and interactions using the SPID. Such an approach might have a clinical potential to predict the sensitivity of patients with mature B cell lymphomas to this class of agents."

Selective degradation of SMARCA2 and dual degradation of SMARCA2 and SMARCA4 has strong antitumor activity in marginal zone lymphoma (MZL) (AACR 2025) - "PRT3789 is currently in phase 1 as a single agent or in combination with docetaxel for patients with solid tumors with loss of SMARCA4...None of the models had mutations in the coding regions of ARID1A or SMARCA4.Adding individual degraders to the BTK inhibitor ibrutinib, the PI3Kδ inhibitor idelalisib, or to the combination of the PI3K inhibitor copanlisib with the BCL2 inhibitor venetoclax led to additivity/synergism... The single SMARCA2 degrader PRT3789 and the dual SMARCA2/4 degrader showed strong dose-dependent cytotoxic activity in MZL cells, showing activity in the low nM range. Both compounds induced apoptosis as single agents and improved the activity of a BTK inhibitor in the two cell lines tested. Interestingly, the antitumor activity was maintained in MZL cell lines with acquired resistance to BTK, PI3K, and BCL2 inhibitors."

Targeting the phosphatidylinositol-3-kinase (PI3K) and mitogen activated protein kinase (MAPK) signalling pathways to enhance chemoradiotherapy in locally advanced rectal cancer. (PubMed, Cancer Treat Res Commun) - "A panel of colorectal cancer (CRC) cell lines (n = 10) with varying PI3K and MAPK mutational backgrounds were treated with combinations of 5-Flourouracil (5-FU), radiation, the PI3K inhibitor copanlisib, and/or the MEK inhibitor refametinib, and their effects on proliferation in vitro were measured...Our results suggest that activation of the kinase signalling pathway may modulate PI3K/MEK inhibitor responsiveness in colorectal cancer. Furthermore, the addition of copanlisib to 5-FU chemoradiotherapy resulted in an enhanced anti-proliferative cytotoxic effect compared to 5-FU chemoradiotherapy alone, regardless of the background mutational status, and supports further clinical development of this regimen."
