Phosphatidylserine Externalization in Cancer: Biology, Immune Suppression, and Emerging Theragnostic Strategies. (PubMed, Int J Mol Sci) - "We further summarize the development and evaluation of PS-targeted therapeutic platforms-such as bavituximab, SapC-DOPS/BXQ-350, and PS-directed imaging agents-and highlight their translational potential in combination with radiotherapy, chemotherapy, and checkpoint inhibitors. Chronic PS externalization, as manifested through distinct cellular and vesicular carriers, represents a unifying biomarker of tumor stress, immune suppression, and therapeutic vulnerability, offering a next-generation axis for theragnostic cancer management."

Bxq-350 in combination with FOLFOX7 and bevacizumab: Evaluation of effect on oxaliplatin-induced CIPN—A phase 1b/2 trial to assess the efficacy and safety of BXQ-350, a first-in-class sphingolipid metabolism modulator, in newly diagnosed metastatic colorectal carcinoma. (ASCO-GI 2026) - P1/2 | "Results show that BXQ-350 was safe and well tolerated in the combination. Data suggest that BXQ-350 may provide additional clinical benefits and may reduce intensity or delay onset of CIPN, allowing for increased cumulative dosing of oxaliplatin and relative dose intensity in 1L mCRC."

BXQ-350: A NOVEL APPROACH TO ACTIVATE GLUCOSYLCERAMIDASE IN PARKINSON'S DISEASE PATIENTS (ADPD 2026) - "BXQ-350 is a novel biologic that lowers significantly circulating levels of key neurotoxic sphingolipids. In PD models, BXQ-350 rescues Gcase activity in in vitro and in vivo. Results of on-going experiments warrant further investigation of BXQ-350 potential clinical opportunity for the treatment of PD patients."

Effect of BXQ-350, a novel sphingolipid metabolism modulator, on neuronal environments through modulation of gene pathways. (ASCO 2025) - "A suite of genes deemed to be implicated in CIPN were investigated looking at the differences in RNA levels between mice DRGs from the BXQ-350 alone, BXQ-350/Oxaliplatin, Oxaliplatin alone, and vehicle alone groups... CIPN is a dangerous side effect of chemotherapy that causes patients to discontinue treatment courses. BXQ-350 has been shown to reduce the burden of CIPN in vivo and in vitro. Instead of directly counteracting the effects of specific chemotherapeutics, BXQ-350 promotes several pathways that regulate neuronal health, cleaning up neurons and promoting homeostatic neuronal environments."

Sphingolipid modulating compounds BXQ-350 and desipramine display synergy in reducing viability across multiple cancer cell types in vitro (AACR 2025) - "Disrupting a cancer cell's sphingolipid metabolism, specifically the Ceramide-S1P rheostat, is a viable strategy for clinical therapeutics. The synergy BXQ-350 and Desipramine combinations show across cancer cell types, with varying oncogenic profiles, suggests that targeting sphingolipid metabolism is an agnostic approach to treating cancer, not related to any specific mutation or cell type. The possibility exists for sphingolipid modulating drugs to be combined with specific chemotherapeutics to increase their efficacy."
