Pembrolizumab with PEGPH20 was safe but did not have significant efficacy in refractory HA-high metastatic PDA."

Targeting hyaluronic acid in pancreatic ductal adenocarcinoma uncovers novel therapeutic opportunities Free (AACRPanCa 2025) - "Systemic administration of Hyaluronidase, via the PEGPH20 formulation, has reduced stromal HA, normalized IFP, and consequently improved the efficiency of the cytotoxic compound, gemcitabine, leading to increased survival in mice...2019, PMID XXXX) along an inducible allele, Rosa26-CreERT2, encoding an inducible Cre-ERT2 recombinase to allow the systemic ablation of the conditional Has2lox alleles in adult mice upon exposure to a Tamoxifen-containing (TAM) diet...Notably, HA depletion enhanced the efficacy of gemcitabine, the anti-CTLA-4 and the panras inhibitor darasonrasib, either alone or in combination of anti-CTLA-4. In summary, HA depletion in PDAC produced multiple changes at different levels that opens up new opportunities for therapeutic interventions."

Hyaluronic Acid and Its Role in Pancreatic Cancer: Mechanisms of Tumor Progression, Drug Resistance, and Therapeutic Targeting. (PubMed, Pharmacol Res) - "However, clinical trials evaluating therapies like PEGPH20 have shown mixed results, suggesting that HA's role in PDAC is complex and context-dependent. This review highlights the dynamic regulation of HA in the TME, the therapeutic strategies targeting HA, and the challenges in translating these strategies into clinical practice. It underscores the need for precision medicine approaches to optimize the targeting of HA for improving patient outcomes in pancreatic cancer."

Pancreatic Neuroendocrine Tumors Secrete Apolipoprotein E to Induce Tip Endothelial Cells That Remodel the Tumor-Stroma Ratio and Promote Cancer Progression. (PubMed, Cancer Res) - "Importantly, mTOR inhibitors synergistically enhanced the antitumor effects of stroma-targeting PEGPH20 in vivo in pNETs. Overall, this study revealed that cancer cell-derived ApoE could induce TipECs to remodel the TSR and that mTOR inhibitors could increase the efficacy of stroma-targeting therapies. Secretion of ApoE by pancreatic neuroendocrine tumor cells engenders a stroma-rich microenvironment, which can be reversed with mTOR inhibitors as part of combination strategies targeting the tumor stroma."

Tumour-derived apolipoprotein E induces tip endothelial cell to remodel tumour stroma ratio and promote pancreatic neuroendocrine tumour progression (ENETS 2025) - "Importantly, mTOR inhibitors effectively compensated for the absence of the anti-stroma PEGPH20 in pNETs. CONCLUSION Our study reveals that tumour-derived APOE could induce TipECs to remodel TSR, and mTOR inhibitors could enhance the efficacy of the anti-stroma PEGPH20."

siRNA-Encapsulated Biomimetic Liposomes Effectively Inhibit Tumor Cells' Hexosamine Biosynthesis Pathway for Attenuating Hyaluronan Barriers to Pancreatic Cancer Chemotherapy. (PubMed, ACS Nano) - "In combination with Doxil, PMLip@siGFAT1 demonstrated potent antitumor efficacy with minimal systemic toxicity. Importantly, unlike PEGPH20 (hyaluronidase), PMLip@siGFAT1 reduced tumor invasiveness, while preserving skeletal muscle integrity. These findings highlight that PMLip@siGFAT1 holds great potential to revitalize HA downregulation strategies in pancreatic cancer for enhanced drug delivery and efficacy."

Investigational Use of Real-World Data as a Hybrid Control in Pancreatic Ductal Adenocarcinoma from the Randomized Phase Ib/II MORPHEUS Trial. (PubMed, Clin Pharmacol Ther) - "The RCT experimental arm (atezolizumab + PEGylated recombinant human hyaluronidase (Atezo + PEGPH20)) was compared with an HC arm consisting of patients treated with modified FOLFOX6 or gemcitabine/nab-paclitaxel from the MORPHEUS PDAC internal control arm supplemented with data from a nationwide EHR-derived de-identified database as the EC arm. The direction and magnitude of hazard ratios (HRs) from the multiple HC analyses (HRs ranged from 1.02 to 1.06) were comparable with the reported trial HR (HR 0.91; 95% CI: 0.56, 1.49). This analysis demonstrates the feasibility and applicability of leveraging RWD in clinical trial design to supplement clinical trial control arms."

Hyaluronidase improves the efficacy of nab-paclitaxel after prolonged angiogenesis inhibition in preclinical models for esophagogastric cancer. (PubMed, Biomed Pharmacother) - "These findings suggest that the mechanical barrier of HA is the major reason responsible for the resistance developed during prolonged anti-angiogenesis in EGC. Incorporating PEGPH20 into the existing treatment regimen is promising to improve outcomes for patients with EGC."
