Strikingly, GGTi-2418@LNP or ketoconazole@LNP combined with T-DXd induced robust and durable tumor regression in HER2-IHC 0 TNBC xenograft models in female mice. Together, this study highlights that targeted inhibition of FBXL2 combined with T-DXd may be a viable therapeutic strategy for treating HER2-IHC 0 solid tumors.
UCS candidemia in children most commonly occurred in patients with solid-hematologic malignancy, central venous catheters and recent antibiotic exposure within 1 week. Female sex, prolonged pre-infection hospitalization, intensive care-related interventions, thrombocytopenia, lower CVC removal rate and elevated C-reactive protein were associated with increased short-term mortality.
Purpose: This study aims to evaluate the effects of itraconazole as a supplementary treatment with paclitaxel and carboplatin on malignancy response and in preventing the initial development of chemoresistance in chemotherapy-naïve patients with advanced ovarian epithelial cancer. Itraconazole was safe and its use was associated with a significant improvement in the quality of life (QOL). Itraconazole could represent a promising add-on therapy to enhance tumor response to chemotherapy in patients with ovarian cancer.
Coadministration of multiple doses of itraconazole, a strong CYP3A4 inhibitor, increased vepdegestrant exposure by 69%, suggesting the involvement of CYP3A4-mediated metabolism, albeit not predominantly, in vepdegestrant elimination.
Management included high-dose acid suppression, short courses of fluconazole for Candida esophagitis, and empiric zinc and riboflavin supplementation; the endoscopic extent of keratinization reduced but persisted, and dysphagia fluctuated without a fixed stricture. Given ongoing symptoms and easy passage of the scope, esophageal manometry was arranged to evaluate a motility contribution, and surveillance endoscopy was planned. This case emphasizes the importance of repeat histology before committing to oncologic pathways, consideration of micronutrient supplementation, cautious use of long-term proton-pump inhibition in patients at risk for Candida, and individualized surveillance where formal guidance is lacking.
This drug-induced partial immunosuppression protocol effectively creates a reproducible state of transient immunodeficiency in outbred mice, suitable for various human tumor xenograft models. It represents a cost-effective and flexible alternative to genetic models, with the distinct advantage of preserving a residual immune microenvironment, making it particularly valuable for preclinical studies that require a partially intact host immune system.
