N2M2/NOA-20: Phase I/IIa umbrella trial of molecularly matched targeted therapies plus radiotherapy in patients with newly diagnosed glioblastoma without MGMT promoter hypermethylation. (ASCO 2024) - P1/2 | "Background: Patients with glioblastoma without MGMT promoter hypermethylation are unlikely to benefit from temozolomide (TMZ)...The alectinib and vismodegib subtrials were closed since no molecularly matching patients were accrued; the idasanutlin subtrial was closed prior to the optimal dose at nine patients at discretion of the company providing the drug... N 2 M 2 allows for elaborate molecular testing being integrated into the treatment decision and efficient determination of treatment activity for patients with newly diagnosed glioblastoma. There is clinical activity of temsirolimus in patients with tumors harboring an activated mTOR pathway although this is not positively prognostic without mTOR inhibition; there is no clinical activity for asunercept and atezolizumab in not molecularly selected patients and also palbociclib in molecularly selected patients."

Computer prediction and genetic analysis identifies retinoic acid modulation as a driver of conserved longevity pathways in genetically diverse Caenorhabditis nematodes. (PubMed, Elife) - "While 11 compounds (aldosterone, arecoline, bortezomib, dasatinib, decitabine, dexamethasone, erlotinib, everolimus, gefitinib, temsirolimus, and thalidomide) either had no effect on median lifespan or were toxic, 5 compounds (all-trans retinoic acid, berberine, fisetin, propranolol, and ritonavir) extended lifespan in Caenorhabditis elegans. While the canonical Akt-target FOXO/DAF-16 was largely dispensable, other conserved Akt-targets (Nrf2/SKN-1 and HSF1/HSF-1), as well as the conserved catalytic subunit of AMPK AAK-2, were all necessary for longevity extension by atRA. Our results highlight the potential of combining computational prediction of longevity interventions with the power of nematode functional genetics and underscore that the manipulation of a conserved metabolic regulatory circuit by co-opting endogenous signaling molecules is a powerful approach for discovering aging interventions."

Real-World Practice Patterns of Patient Management in the Peri-CAR T-Cell Therapy Setting for Patients with Mantle Cell Lymphoma: An International Survey on Behalf of the EBMT Lymphoma Working Party (ASH 2024) - "Nearly all (96%) clinicians took into account the impact of bendamustine on T-cell fitness, avoiding it completely (43%) or limiting its use to first-line (53%)...The preferred chemotherapy regimens included R-BAC (35%), R-GEMOX (31%) and cyclophosphamide-based (12%). Alternative regimens, such as R-Lenalidomide, Bortezomib or Temsirolimus, were rarely selected...Conversely, there was a higher use of ongoing single-agent ibrutinib (38% vs 7%) and a similar rate of pirtobrutinib monotherapy (23% vs 26%)...A similar approach was adopted with venetoclax, where a clear majority of participants stopped it prior to LDC (90%); only 1 respondent maintained it after infusion. Conclusion : These findings confirm the current heterogeneity of MCL patient management strategies prior to CAR T-cell therapy and highlight the need to develop consensus guidelines harmonizing the role of BTKi and other targeted molecules across leukapheresis, bridging and infusion."

Interim results confirm the safety and feasibility of autologous hybrid TREG/Th2 T stem cells (RAPA-501) in ALS patients with severe respiratory insufficiency (ALS-MND 2025) - P | " RAPA-501 were manufactured from apheresis products from pwALS using mTORC1/mTORC2 inhibition (temsirolimus) and differentiation cytokines (IL-2, TGF-b, IL-4). Hybrid TREG/Th2 RAPA-501 cells were feasibly manufactured, consistently expressed an effector TREG/Th2 phenotype, and safely administered to pwALS with severe respiratory insufficiency. Pulmonary and disease activity measures were relatively stable post-RAPA-501 therapy, with a potentially favorable overall survival pattern. RAPA-501 T stem cells therefore represents a potentially new approach for therapy of advanced-stage ALS."

Temsirolimus targets chemoresistant uveal melanoma via mammalian target of rapamycin inhibition and enhances chemotherapy. (PubMed, Anticancer Drugs) - "In this study, we established chemoresistant uveal melanoma cell lines by exposing parental cells to dacarbazine, cisplatin, or gemcitabine and performed high-throughput drug screening incorporating normal human epidermal melanocytes (NHEMs) as a normal control to assess both efficacy and selectivity. Our screening identified temsirolimus and selumetinib as top candidates, with temsirolimus exhibiting strong tumor-selective cytotoxicity...Mechanistically, temsirolimus downregulated mammalian target of rapamycin (mTOR) signaling, as indicated by reduced p-mTOR, p-S6, and p-4EBP1 expression in tumor tissues. These findings demonstrate that temsirolimus selectively targets chemoresistant uveal melanoma cells, enhances chemotherapy efficacy, and suppresses tumor growth via mTOR inhibition, supporting its potential clinical application as a novel therapeutic strategy for chemoresistant uveal melanoma."

DOES MAINTENANCE THERAPY IMPROVE SURVIVAL OF PATIENTS WITH INTERMEDIATE-RISK RHABDOMYOSARCOMA TREATED WITH VAC/VI CHEMOTHERAPY? A REPORT FROM THE CHILDREN'S ONCOLOGY GROUP (SIOP 2025) - "Background and Aims All patients on the ARST1431 intermediate-risk rhabdomyosarcoma (IR-RMS) trial received vinorelbine and cyclophosphamide (VinoC) maintenance for 6 months following 42 weeks of vincristine, dactinomycin, and cyclophosphamide/irinotecan (VAC/VI) ± temsirolimus induction. Addition of VinoC maintenance to VAC/VI induction statistically significantly improved 4-year post-induction EFS and OS, with IPTW-adjusted hazard ratios of 0.61 (95% CI: 0.43–0.86) for EFS and 0.46 (95% CI: 0.28–0.74) for OS. Conclusions Adding VinoC maintenance to VAC/VI induction did not improve the survival of IR-RMS from enrollment compared to VAC/VI alone; however, among patients who completed VAC/VI induction, there was a statistically significant improvement in post-induction survival with the addition of maintenance therapy."

Prolonged exposure to axitinib alters the molecular profile of Caki-2 renal cell carcinoma cells. (PubMed, Mol Clin Oncol) - "Notably, the 50% inhibitory concentration (IC50) values of axitinib and sunitinib were significantly higher in Caki/AX cells than those in Caki-2 cells, indicating 2.83- and 1.2-fold resistance, respectively. By contrast, the IC50 values of sorafenib and erlotinib were decreased in Caki/AX cells. Moreover, Caki/AX cells showed resistance to everolimus, temsirolimus and rapamycin, and decreased sensitivity to vinblastine, vincristine, paclitaxel, doxorubicin and SN-38 compared with Caki-2 cells. Notably, etoposide, 5-fluorouracil, cisplatin and carboplatin sensitivities were comparable in both cell types...A PCR array related to vascular endothelial growth factor signalling showed that the mRNA levels of FIGF (also known as vascular endothelial growth factor D) and sphingosine kinase 1 were upregulated, whereas those of Rac family small GTPase 2 were downregulated in Caki/AX cells. Overall, these findings suggested that the upregulation of the ATP-binding cassette..."
