Efficacy of Daily IV Administration of Dornase Alfa Up to 14 Days Post Subarachnoid Hemorrhage on Functional Independence At 6 Months: a PROBE Multicenter Open-label Randomized Controlled Trial

Subarachnoid hemorrhage due to aneurysm rupture (SAH) results in high mortality, while survivors frequently suffer reduced quality of life and even loss of autonomy, particularly in the active population. A significant proportion of this morbidity and mortality is linked to the occurrence of delayed cerebral ischemia (DCI), defined as a new focal neurological deficit or reduced level of consciousness unrelated to the treatment of the aneurysm or a concomitant condition.
DCI mainly occurs between days 4 and 14 after SAH, with an estimated incidence of 30%, and is significantly associated with an unfavorable functional prognosis at 3 months. Currently, the only treatment for post-SAH DCI is to prevent or reverse the onset of vasospasm, with limited efficacy, for example through nimodipine administration or hemodynamic optimization. However, according to existing data, vasospasm is not the only cause of DCI, as it may occur elsewhere than in the arterial territory affected by vasospasm, or even in the absence of any vasospasm at all. Recent reviews of the literature highlight the role of microvascular thrombo-inflammation in the pathophysiology of DCI.
This phenomenon begins as soon as SAH occurs, with the appearance of multiple microvascular obstructions responsible for ischemia of downstream territories and loss of distal autoregulatory capacity. Among the effectors of thrombo-inflammation, the NETose phenomenon (production of NETs - Neutrophil Extracellular Traps or extracellular DNA network) has recently been associated with the onset of DCI. Indeed, the concentration of NETs increases in the cerebrospinal fluid (CSF) and blood of SAH patients, and correlates with the severity of the hemorrhage. Furthermore, intravenous or intraperitoneal administration of DNAse in an animal model of SAH has been shown to reduce NET concentration and improve functional prognosis by acting directly on cerebral perfusion through the reduction of micro-thrombosis.
In humans, recombinant DNAse (dornase alfa, Pulmozyme®) has marketing authorization for inhaled administration in cystic fibrosis. The toxicology report accompanying the marketing authorization demonstrates the absence of serious side effects following administration of high IV doses of Pulmozyme® in monkeys and rats. Other studies evaluating IV administration of bovine DNAse at high doses report no complications.
In 1999, a study was published evaluating intravenous (IV) Pulmozyme® in lupus patients, reporting no serious adverse events (SAEs) among the 14 patients receiving the treatment. We are currently conducting a clinical trial of the same molecule in IV administration in patients treated with mechanical thrombectomy and IV thrombolysis for ischemic stroke (NCT04785066).
This study is the first randomized clinical trial to target NETs as effectors of the thrombo-inflammation responsible for post-HSA DCI.

Inhalable DNase I@Au hybrid nanoparticles for radiation sensitization and metastasis inhibition by elimination of neutrophil extracellular traps

Article

Author: He, Jian ; Chen, Weiyu ; Sun, Yuchao ; Zheng, Yichun ; Zhou, Min ; Wang, Kai ; Wang, Yongfang

High-dose radiation therapy is a widely used clinical strategy to inhibit tumor growth. However, the rapid generation of excessive reactive oxygen species (ROS) triggers the formation of neutrophil extracellular traps (NETs), which capture free tumor cells in the bloodstream, promoting metastasis. In this study, we developed a hybrid nanoparticle composed of DNase I and gold (DNase I@Au) to enhance radiotherapy efficacy while mitigating metastasis by precisely eliminating NETs. The DNase I@Au nanoparticles, administered via aerosol inhalation, are efficiently delivered to lung tumor tissue, improving radiosensitization and reducing tumor size. Crucially, the nanoparticles could gradually release DNase I, effectively degrading ROS-induced NETs and preventing the interaction of free malignant cells with tumor sites or vasculature, thereby inhibiting metastasis. Therefore, we provide an enzyme and sensitizer co-loaded strategy that offers a promising approach to improve the therapeutic outcome of radiotherapy and reduce the risk of lung cancer metastasis under ROS stimulation.

Advances in preparation of acellular human dermis for tissue banking and transplantation

Article

Author: Barrera, Valentina ; Randles, Michael ; Stern, Irit ; Rooney, Paul

Abstract:

Non-healing wounds cost the National Health Service over £5.6 billion annually in wound management. Skin allografts are used to treat non-healing wounds, ulcers and burns, offering the best protection against infection. In order to allow host cells to repopulate and to avoid immunogenicity, cell components are removed through decellularisation. Decellularisation of human dermis has so far been performed in NHS Blood and Transplant using a combination of two enzymes (RNase T1 and the recombinant human DNase Pulmozyme)®. This study aims at validating a new method to remove DNA from donated dermis via the use of a single enzyme, Benzonase, known for its effectiveness of DNA digestion. Skin samples were decellularised by removing the epidermis, lysing of dermal cells, removal of cellular fragments by a detergent wash and removal of nucleic acids by a nuclease incubation with either Benzonase or Pulmozyme + RNase T1. DNA quantification with PicoGreen, as well as histology on wax-embedded biopsies, stained with DAPI and haemotoxylin and eosin, were performed. In vitro toxicity test on human osteosarcoma immortalised cells and skin fibroblasts, and biomechanical (tensile) testing, were also performed. The effectiveness of DNA digestion with the new methodology was comparable to previous procedure. Mean DNA removal percentage following decellularisation with Pulmozyme + RNase was 99.9% (3.83 ng/mg). Mean DNA removal percentage with Benzonase was 99.8% (9.97 ng/mg). Histology staining showed complete decellularisation following either method. Benzonase was proven to be non-toxic to both cell lines used, and a one-way Anova test showed no significant difference in neither stress nor strain between acellular dermal matrix decellularised with either Benzonase or Pulmozyme + RNase T1. Benzonase was able to effectively decellularise dermis after prior removal of epidermis. It performed just as well as the combination of Pulmozyme + RNase T1, but represents significant advantages in terms of cost effectiveness, procurement and storage; Benzonase has been successfully used in the decellularisation of other tissues, thus would be better for Tissue Banking use. Switching to this combined DNase/RNase can have far-reaching consequences in the production of acellular human dermal matrix by NHSBT and in the treatment of patients requiring it.

Nano-alkaline ion-excited NETs ablative eye drops promote ocular surface recovery

Article

Author: Zhang, Lichen ; Zou, Xi ; Sun, Zhuo ; Zhang, Jun ; Deng, Guohua ; Xi, Kun ; Li, Ziang ; Liu, Zhinan ; Sun, Shanshan ; Zhu, Lin

Neutrophil extracellular traps (NETs) promote neovascularization during the acute phase after ocular chemical injury, while the local inflammatory acidic environment delays post-injury repair. Currently, the mechanism of NETs promoting neovascularization has not been fully elucidated, and there is a lack of therapeutic strategies to effectively improve the local microenvironment for corneal repair. In this study, we validated the NETs-M2-angiogenic pathway after injury. Using transcriptomics sequencing and liquid-phase microarray assays, the intrinsic immune cascade mechanism of NETs inducing macrophage M2 polarization and releasing VEGF via PI3K/AKT was identified. Based on this pathology and the physiological need to improve the local inflammatory acidic environment and promote corneal repair, we organically integrated the alkaline ion-rich bioglass with the highly transmissive and highly adhesive filipin protein, and constructed NETs ablative gel eye drops (DMS) that can release DNase I and alkaline ions in a sustained manner. The eye drops restricted the inflammatory interaction of NETs with macrophages from the source, adhered to the corneal surface and continuously released alkaline ions to improve the local acidic inflammatory environment, providing a favorable immune microenvironment for corneal recovery. We established a cell co-culture system and a corneal alkali burn model to further validate the role of DMS in modulating the intrinsic immune cascade of neovascularization for corneal repair and the related mechanisms. In conclusion, based on the biological mechanism of NETs-M2-VEGF after corneal chemical injury, the present study designed eye drops for dual regulation of intrinsic immunity and the inflammatory acid environment, which not only further supplemented and improved the pathophysiological mechanism of corneal neovascularization after chemical injury, but also provided a new way of thinking about corneal regeneration after injury.

Xenetic Biosciences, Inc. Extends Research Agreement with the University of Virginia for the Advancement of its DNase-Based Oncology Platform

Company continuing to advance DNase-based oncology program towards clinical proof-of-concept studies in multiple indications FRAMINGHAM, MA / ACCESSWIRE / December 16, 2024 / Xenetic Biosciences, Inc. (NASDAQ:XBIO) ("Xenetic" or the "Company"), a biopharmaceutical company focused on advancing innovative immuno-oncology technologies addressing hard to treat cancers, today announced it has extended its previously announced Research Funding Agreement (the "Agreement") with the University of Virginia ("UVA") to advance the development of its systemic DNase program through 2025. Xenetic's DNase-based oncology platform is designed to target neutrophil extracellular traps (NETs), which are weblike structures composed of extracellular chromatin coated with histones and other proteins. In cancer, NETs are expelled by activated neutrophils into the tumor microenvironment (TME) and blood, thereby promoting cancer spread, local and systemic immunosuppression, as well as cancer-associated thrombosis. Reduction of NETs burden via application of Xenetic's proprietary recombinant human DNase I has been shown to improve efficacy of immunotherapy, adoptive cell therapy and chemotherapy in preclinical animal models."Allan Tsung, MD, and the team at UVA continue to be valued partners and we are pleased with the progress under the Agreement in evaluating the potential addition of DNase to available treatment options in areas of significant unmet need. The preclinical and translational data that UVA has accumulated under the initial Scope of Work to the Agreement further strengthens the scientific rationale for investigating combinations of DNase I with immunotherapies and chemotherapies. In the next phase of this partnership, UVA will continue to investigate combinations of DNase I with immunotherapies in models of primary and metastatic colorectal cancer. As a surgical oncologist and scientist, Dr. Tsung is internationally recognized for leading substantial research on the role of NETs in tumor growth, metastasis, and resistance to existing cancer therapies and we look forward to leveraging that expertise as we advance our technology toward the clinic," commented Reid P. Bissonnette, Ph.D., Executive Consultant for Translational Research and Development of Xenetic.Under the terms of the Agreement, in addition to advancing Xenetic's existing intellectual property, Xenetic has an option to acquire an exclusive license to any new intellectual property arising from the DNase research program. Allan Tsung, MD, a member of the Company's Scientific Advisory Board and Chair of the Department of Surgery at the UVA School of Medicine, will continue to oversee the research conducted under the Agreement.
