Catalent is the global leader in enabling biopharma, cell, gene, and consumer health partners to optimize development, launch, and supply of better patient treatments across multiple modalities.
"We are pleased to be working with a preeminent contract development and manufacturing organization such as Catalent, and to have the opportunity to leverage their broad expertise and successful track record with early-stage development through commercial manufacturing. We are excited to take this step forward on the path to the clinic and look forward to investigating systemic DNase as an adjunctive therapy for locally advanced or metastatic cancers," commented, Jeffrey Eisenberg, Chief Executive Officer of Xenetic.
"This agreement is an important step towards long-term collaboration betweenCatalent and Xenetic," added Vikalp Mohan, Global Vice President, Head of Drug Substance at Catalent Biologics. "We look forward to leveraging Catalent’s proven biomanufacturing expertise at our site in Madison, Wisconsin to support the advancement of Xenetic’s DNase clinical development program and accelerating their path to first-in-human studies."
Xenetic’s interventional DNase based oncology platform is aimed at improving outcomes of existing treatments, including immunotherapies. The Company exclusively licensed intellectual property for uses of DNases in cancer include systemic co-administration of DNases along with standard therapies, including chemotherapy, radiation and checkpoint inhibitors, or along with conventional chimeric antigen receptor (CAR) T therapies.
The DNase platform is designed to target neutrophil extracellular traps ("NETs"), which are weblike structures composed of extracellular chromatin coated with histones and other proteins. NETs are expelled by activated neutrophils, in response to microbial or pro-inflammatory challenges. However, excessive production or reduced clearance of NETs can lead to aggravated inflammatory and autoimmune pathologies, as well as creation of pro-tumorigenic niches in the case of cancer growth and metastasis.
The Company is working toward its planned first-in-human study to evaluate DNase combined with immune checkpoint inhibitors or chemotherapy.
