FRAMINGHAM, MA / ACCESSWIRE / May 12, 2022 / Xenetic Biosciences, Inc. (NASDAQ:XBIO) ("Xenetic" or the "Company"), a biopharmaceutical company focused on advancing innovative immune-oncology technologies addressing hard to treat oncology indications, today reported its financial results for the first quarter of 2022 and provided a business update.
"Our strategic focus throughout the first quarter was working towards the completion of our exclusive license agreement with CLS Therapeutics ("CLS") to develop its interventional DNase based oncology platform. This platform was extremely attractive to us as we realized that adding the licensed programs could expand and enhance our oncology pipeline, provide an accelerated path to the clinic, create the potential for value-driving clinical and regulatory milestones, and position us as an emerging clinical-stage company," commented, Jeffrey Eisenberg, Chief Executive Officer of Xenetic. "Our team, along with advisors and preeminent key opinion leaders in this space, will make it a priority to advance the systemic DNase program into the clinic as an adjunctive therapy for locally advanced or metastatic cancers, as quickly and efficiently as possible."
DNase Oncology Platform: Targeting Neutrophil Extracellular Traps ("NETs") to improve cancer therapies with a focus on advancing systemic DNase program into the clinic as an adjunctive therapy for locally advanced or metastatic cancers.
The Company's interventional DNase based oncology platform is aimed at improving outcomes of existing treatments, including immunotherapies. The exclusive license to CLS' 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. In addition, the licenses cover "DNase-armored" CAR T therapies in which novel CAR T products are engineered to secrete DNases into the tumor microenvironment to potentially improve T-cell infiltration, activity and persistence.
The licensed DNase platform is designed to target 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.
A substantial amount of scientific literature has implicated NETs in the context of cancer pathogenesis and resistance to cancer therapies (including chemo, radio, and immunotherapies such as checkpoint inhibitors and cell therapies). In published reports, elevated levels of NETs have been a biomarker associated with poor prognosis in patients with a variety of cancers.
In addition, resistance to existing therapeutic agents can involve the release of immunosuppressive signaling factors from NETs, or physical barriers created by NETs which can impede the infiltration, activity, and survival of cytotoxic T cells in the tumor microenvironment.
Published pre-clinical models have demonstrated the effectiveness of systemically administered DNase, alone or in combination with other agents, for the elimination of NETs and prevention of tumor growth and metastasis.
Adoptive transfer of CAR T cells has emerged as one of the most promising advances in cancer immunotherapy. Engineered CAR T cells, designed to recognize cancer-associated antigens, are capable of sustained and selective killing of tumor cells, with substantial reduction of tumor burden. CAR T therapies have exhibited remarkable clinical success against hematological malignancies but thus far have failed to demonstrate success in the context of solid tumors. Recent approaches to CAR T design include "armored" CAR-T cells, so named because they can express additional factors to resist immunosuppression or degrade physical components of the tumor's extracellular matrix, including NETs. The Company plans to conduct pre-clinical research with the goal of demonstrating that armoring CAR T cells to secrete DNase can support depth and durability of response against solid tumor indications.
- In April 2022, executed exclusive license and sublicense agreements with CLS Therapeutics to develop its interventional DNase based oncology platform, which is aimed at improving outcomes of existing treatments, including immunotherapies.
- Advancing toward first-in-human study with IND filing targeted for the end of 2023.
- Systemic DNase program initially targeting multi-billion-dollar indications including pancreatic carcinoma.
- DNase armored CAR T program focused on demonstrating that armoring CAR T cells to secrete DNase can support depth and durability of response against solid tumor indications.
XCART Platform Technology: Significantly differentiated, proprietary approach to personalized CAR T lymphoma therapy targeting tumor-specific neoantigens that target independently of CD19 or other surface antigens that are common to both normal and malignant B-cells.
- Advancing preclinical efforts through ongoing research and development collaborations including with The Scripps Research Institute and other institutions in the U.S. covering design and implementation of the pre-clinical development program, as well as activities supporting process development for clinical manufacturing.
- Bolstered intellectual property portfolio with issuance of a U.S. patent covering the co-administration of XCART-derived CAR T cells, together with a personalized vaccine designed to enhance the effectiveness of the CAR T therapy.
PolyXen Platform Technology: Patent-protected platform technology designed for protein or peptide therapeutics, enabling next-generation biological drugs by prolonging a drug's circulating half-life and potentially improving other pharmacological properties.
- Royalty payments of approximately $0.4 million were received in the three months ended March 31, 2022, representing an approximate 103.4% increase over the same period in 2021 as Takeda's sublicensee continued its worldwide launch of the product.
Summary of Financial Results for First Quarter 2022
Net loss for the quarter ended March 31, 2022 was approximately $1.6 million. Research & development expenses for the three months ended March 31, 2022 increased by approximately $0.5 million, or 74.9%, to approximately $1.1 million from approximately $0.6 million in the comparable quarter in 2021. The increase was primarily due to the Company's increase in spending related to XCART™ U.S. pre-clinical development efforts. General and administrative expenses for the three months ended March 31, 2022 decreased by approximately $23,000, or 2.5%, to approximately $0.9 million from approximately $0.9 million in the comparable quarter in 2021. The decrease was primarily due to lower consulting costs offset by an increase in legal costs related to the CLS transaction during the three months ended March 31, 2022 compared to the same period in 2021.
The Company ended the quarter with approximately $16.2 million of cash.
