PIK3CA (Phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha)

P=N/A, N=305, Active, not recruiting, Shanghai Chest Hospital | Recruiting --> Active, not recruiting | Trial completion date: Mar 2026 --> Dec 2027 | Trial primary completion date: Mar 2025 --> Dec 2026

A 62-year-old man with metastatic PSA underwent splenectomy followed by first-line paclitaxel, achieving stable disease for 7 months...Sequential treatment with liposomal doxorubicin, eribulin, toripalimab, and lenvatinib failed to control the disease failed to control the disease...To our knowledge, this is the first reported use of inavolisib in angiosarcoma. The rapid biochemical and radiological response observed in this PIK3CA-mutated PSA supports early genomic profiling to identify actionable alterations and warrants prospective evaluation of combined phosphoinositide 3-kinase and vascular endothelial growth factor pathway inhibition in refractory angiosarcoma.

These net costs amount to $0.88 per-member-per-month. While introduction of capivasertib could reduce adverse event and follow-up costs, it may result in an overall increase in payers' budget.

A transcriptional signature associated with SARM sensitivity was identified, primarily driven by proliferation-related processes, consistent with a significant decrease in S-phase cell cycle proteins upon treatment in EP0062-sensitive models. In some EP0062-resistant tumors, the combination with palbociclib enhanced the antitumor effect of EP0062, suggesting a potential strategy for metastatic patients with acquired ET resistance.

Additionally, a 100 ns MD Simulation has resulted in far less deviation, fluctuations, and intermolecular interactions than Tucatinib, suggesting stable protein-ligand interactions, while the binding free energy and total complex energy computed across 0-1000 frames of the MD trajectories indicate that 2-Aoeobenoxmide is a promising in silico candidate. Importantly, because the entire study is computational, the findings should be interpreted as in silico hypotheses, and experimental validation through in vitro and in vivo assays is warranted before any clinical translation is considered.

Our findings suggest HIV-1 dysregulates cervical cell signaling via paracrine mechanisms to phenocopy PIK3CA-activating mutations through IRS1-PI3K-AKT pathway activation. Our findings highlight IRS1 and the PI3K pathway as a potential therapeutic target for cervical cancer in women living with HIV-1.

Notably, low-dose Capivasertib, an AKT inhibitor targeting tumors with PIK3CA/AKT1/PTEN mutation(s), induced senescence selectively in FUCA2-high LUAD irrespective of PIK3CA/AKT1/PTEN/TP53 mutational status, and its combination with the nutraceutical senolytic procyanidin C1 achieved potent and low-toxicity suppression of LUAD across multiple preclinical models. Together, our results uncover the FUCA2-ErbB3 fucosylation-AKT pathway as a central regulator of senescence and propose a FUCA2-guided drug repurposing strategy for LUAD.

Moving forward, the "HER2-positive" designation must be refined through integrated, biomarker-driven frameworks. Incorporating these molecular nuances into prospective clinical trials is essential for optimizing therapeutic de-escalation and overcoming the persistent challenges of resistance in HER2-targeted care.

Due to limited germline and epigenetic data, MSI-H tumors could not be classified as Lynch-associated or sporadic. Overall, MSI-H and MSS CRCs in the Chinese population demonstrate distinct molecular landscapes in terms of TMB, HRD, EBV status, and driver gene alterations, underscoring the molecular heterogeneity of MSI-H CRC and the need for future studies integrating germline and epigenetic data to refine subtype classification.

Future studies should focus on evaluating the efficacy of PI3K inhibitors, alone or in combination with immunotherapy and other targeted treatments, in selected patients. This evaluation should be based on molecular alterations that may predict therapeutic benefit.

We retrospectively analyzed 20 patients with newly diagnosed primary IDH-wildtype glioblastoma who underwent gross-total resection followed by standard radiotherapy and temozolomide treatment between 2016 and 2022...However, given the limited sample size, the selection of extreme survival groups, and the predominance of chromosomal polysomy detected by FISH, these findings should be interpreted as hypothesis-generating only. Further validation in larger cohorts using high-resolution genomic methods is warranted.

This large clinicogenomic study in an Asian population highlights unique mutational landscapes and survival associations, which may inform personalized treatment strategies.
