Xenetic Biosciences, Inc. (NASDAQ: XBIO) Announces Agreement to Acquire Innovative CAR T Technology Platform

On March 4, 2019 Xenetic Biosciences, Inc. (NASDAQ: XBIO) ("Xenetic" or the "Company"), a clinical-stage biopharmaceutical company focused on the discovery, research and development of next-generation biologic drugs and novel orphan oncology therapeutics, reported its agreement to acquire the novel CAR T ("Chimeric Antigen Receptor T Cell") platform technology, called "XCART," a proximity-based screening platform capable of identifying CAR constructs that can target patient-specific tumor neoantigens, with a demonstrated proof of mechanism in B-cell Non-Hodgkin lymphomas (Press release, Xenetic Biosciences, MAR 4, 2019, View Source [SID1234533946]). The XCART technology, developed by The Scripps Research Institute ("Scripps") in collaboration with the Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry, is believed to have the potential to significantly enhance the safety and efficacy of cell therapy for B-cell lymphomas by generating patient- and tumor-specific CAR T cells. The acquisition is subject to conditions typical for a transaction of this kind, including appropriate stockholder approvals, and is expected to close in the first half of 2019.

"This acquisition is a transformative step in the strategic evolution of Xenetic," commented Jeffrey Eisenberg, Chief Executive Officer of Xenetic. "With this novel and differentiated CAR T technology, we are now positioned in a field that is at the forefront in the development of new oncology therapeutics, which we believe will drive significant value for shareholders. The XCART platform was designed to target personalized, patient-specific tumor neoantigens and has demonstrated promising preclinical data in an area of significant unmet medical need. Our R&D efforts will focus initially on leveraging the XCART platform to develop cell-based therapeutics for the treatment of B-cell Non-Hodgkin lymphomas, an initial global market opportunity estimated to exceed $5 billion per year."*

The XCART technology platform was designed by its originators to utilize an established screening technique to identify peptide ligands that bind specifically to the unique B-cell receptor ("BCR") on the surface of an individual patient’s malignant tumor cells. The peptide is then inserted into the antigen-binding domain of a CAR, and a subsequent transduction/transfection process is used to engineer the patient’s T cells into a CAR T format which redirects the patient’s T cells to attack the tumor. Essentially, the XCART screening platform is the inverse of a typical CAR T screening protocol wherein libraries of highly specific antibody domains are screened against a given target. In the case of XCART screening, the target is itself an antibody domain, and hence highly specific by its nature. The XCART technology creates the possibility of personalized treatment of lymphomas utilizing a CAR with an antigen-binding domain that should only recognize, and only be recognized by, the unique BCR of a particular patient’s B-cell lymphoma.

Matthew John Frigault, M.D., a member of Xenetic’s Scientific Advisory Board and medical oncologist in the Hematologic Malignancy Program at the Massachusetts General Hospital Cancer Center, Assistant Director of the Cellular Therapy Service, and Instructor at Harvard Medical School commented, "Adoptive cell therapy, and CAR T in particular, has been an area of great interest in recent years, and an area that I have built my career around. There are a number of CAR T products in development and the existing therapies can be highly efficacious, but not all patients respond, and the side effects can be frequent and serious, even life threatening."

An expected result for XCART is limited off-tumor toxicities, such as B-cell aplasia. Xenetic’s clinical development program will seek to confirm the early preclinical results, and to demonstrate a more attractive safety profile than existing therapies.

Under the terms of the transaction, Xenetic will acquire all outstanding shares of Hesperix S.A., a newly-formed Swiss entity to which all XCART owners and inventors other than Scripps have assigned their rights to XCART, and will exclusively license Scripps’ rights in the technology, in exchange for an aggregate 7,500,000 shares of Xenetic common stock.

Decision on GIAPREZA MAA by EMA Expected in June of 2019: La Jolla expects a decision on the GIAPREZA Marketing Authorisation Application (MAA) by the European Medicines Agency (EMA) in June of 2019.

Investigational Products Update

NDA Planned for New Investigational Product, LJPC-0118, for the Treatment of Severe Malaria, in Fourth Quarter of 2019: La Jolla plans to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019 for LJPC-0118. LJPC-0118 is La Jolla’s new investigational product for the treatment of severe malaria. The active pharmaceutical ingredient in LJPC-0118 was demonstrated to be superior to quinine in reducing mortality in patients with severe falciparum malaria infection in two randomized, controlled, clinical studies.

Topline Results of Phase 2 Study of LJPC-401 in Patients with Hereditary Hemochromatosis Expected in Second Half of 2019: La Jolla expects topline results in the second half of 2019 for LJ401-HH01, a multinational, multicenter, randomized, Phase 2 study that is designed to evaluate the safety and efficacy of LJPC-401, La Jolla’s proprietary formulation of synthetic human hepcidin, as a treatment for hereditary hemochromatosis (HH). The primary efficacy endpoint of the study is the change in transferrin saturation, a standard measurement of iron levels in the body and one of the two key measurements used to detect iron overload, from baseline to end of treatment.

Topline Results of Pivotal Study of LJPC-401 in Patients with Beta Thalassemia Expected in Mid-2020: La Jolla expects topline results in mid-2020 for LJ401-BT01, a pivotal, multinational, multicenter, randomized, controlled study that is designed to evaluate the safety and efficacy of LJPC-401 as a treatment for beta thalassemia (BT) patients who, despite chelation therapy, have cardiac iron levels above normal. The primary efficacy endpoint of this study is the change in iron content in the heart after 6 months, as measured by cardiac magnetic resonance imaging (MRI). If this study is successful, La Jolla anticipates filing an MAA for LJPC-401 in the European Union (EU).

"We are excited to have launched GIAPREZA, our first commercial product, in 2018, and we look forward to executing on a number of initiatives that we believe will support its continued, increased adoption in 2019," said George Tidmarsh, M.D., Ph.D., La Jolla’s President and Chief Executive Officer. "Our two randomized studies of LJPC-401 in BT and HH have the potential to demonstrate improved patient outcomes in these important diseases. Furthermore, we are excited to have recently announced a planned NDA submission for LJPC-0118, our new investigational product for the treatment of severe malaria, in the fourth quarter of 2019."

About LJPC-0118

LJPC-0118 is La Jolla’s investigational product for the treatment of severe malaria. The active pharmaceutical ingredient in LJPC-0118 was demonstrated to be superior to quinine in reducing mortality in patients with severe falciparum malaria infection in two randomized, controlled, clinical studies. La Jolla plans to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019 for LJPC-0118. Severe malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito, which feeds on humans. Symptoms include but are not limited to: fever, chills, sweating, hypoglycemia and shock. Severe malaria is often complicated by central nervous system infections that may lead to delirium, which may progress to coma. Infections usually occur a few weeks after being bitten. In 2017, an estimated 219 million cases of malaria occurred worldwide, with an estimated 200 million of these cases occurring in the World Health Organization (WHO) African Region, and, in 2013, the global annual incidence of severe malaria was estimated to be 2 million cases. In 2017, an estimated 435,000 people died from malaria worldwide.

About LJPC-401

LJPC-401, a clinical-stage investigational product, is La Jolla’s proprietary formulation of synthetic human hepcidin. Hepcidin, an endogenous peptide hormone, is the body’s naturally occurring regulator of iron absorption and distribution. In healthy individuals, hepcidin prevents excessive iron accumulation in vital organs, such as the liver and heart, where it can cause significant damage and even result in death. La Jolla is developing LJPC-401 for the potential treatment of iron overload, which occurs as a result of primary iron overload diseases such as hereditary hemochromatosis (HH), or secondary iron overload diseases such as beta thalassemia, sickle cell disease (SCD), myelodysplastic syndrome (MDS) and polycythemia vera. The European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP) has designated LJPC‑401 as an orphan medicinal product for the treatment of beta thalassemia intermedia and major and SCD.

"There is a significant unmet need for new therapies that offer quality-of-life advantages for patients with advanced breast cancer," said Lee Schwartzberg, M.D., Executive Director, West Cancer Center, and Professor of Medicine, University of Tennessee Health Science Center. "While patients with advanced disease often recur after having previously received a taxane with their breast cancer surgery, many have no prior taxane exposure because they are diagnosed when their disease is already advanced and inoperable or they did not receive chemotherapy with their breast cancer surgery. CONTESSA 2 is designed to complement CONTESSA, a Phase 3 study in taxane-experienced patients, by investigating the same tesetaxel-containing regimen in patients who have not previously received a taxane."

About Tesetaxel

Tesetaxel is an investigational, orally administered chemotherapy agent that belongs to a class of drugs known as taxanes, which are widely used in the treatment of cancer. Tesetaxel has several pharmacologic properties that make it unique among taxanes, including: oral administration with a low pill burden; a long (~8-day) terminal plasma half-life in humans, enabling the maintenance of adequate drug levels with relatively infrequent dosing; no history of hypersensitivity (allergic) reactions; and significant activity against chemotherapy-resistant tumors. In patients with metastatic breast cancer, tesetaxel was shown to have significant, single-agent antitumor activity in two multicenter, Phase 2 studies.

About CONTESSA 2

CONTESSA 2 is a multinational, multicenter, Phase 2 study of tesetaxel, an investigational, orally administered taxane, in patients with locally advanced or metastatic breast cancer (LA/MBC). CONTESSA 2 is investigating tesetaxel dosed orally at 27 mg/m2 on the first day of each 21-day cycle plus a reduced dose of capecitabine (1,650 mg/m2/day dosed orally for 14 days of each 21-day cycle) in approximately 125 patients with human epidermal growth factor receptor 2 (HER2) negative, hormone receptor (HR) positive LA/MBC not previously treated with a taxane. Capecitabine is an oral chemotherapy agent that is considered a standard-of-care treatment in LA/MBC. Where indicated, patients must have received endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor. The primary endpoint is objective response rate (ORR) as assessed by an Independent Radiologic Review Committee (IRC). The secondary efficacy endpoints are duration of response (DoR) as assessed by the IRC, progression-free survival (PFS) as assessed by the IRC, disease control rate (DCR) as assessed by the IRC and overall survival (OS).

About CONTESSA

CONTESSA is a multinational, multicenter, randomized, Phase 3 study of tesetaxel, an investigational, orally administered taxane, in patients with locally advanced or metastatic breast cancer (LA/MBC). CONTESSA is comparing tesetaxel dosed orally at 27 mg/m2 on the first day of each 21-day cycle plus a reduced dose of capecitabine (1,650 mg/m2/day dosed orally for 14 days of each 21-day cycle) to the approved dose of capecitabine alone (2,500 mg/m2/day dosed orally for 14 days of each 21-day cycle) in approximately 600 patients randomized 1:1 with human epidermal growth factor receptor 2 (HER2) negative, hormone receptor (HR) positive LA/MBC previously treated with a taxane in the neoadjuvant or adjuvant setting. Capecitabine is an oral chemotherapy agent that is considered a standard-of-care treatment in LA/MBC. Where indicated, patients must have received endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor. The primary endpoint is progression-free survival (PFS) as assessed by an Independent Radiologic Review Committee (IRC). CONTESSA’s secondary efficacy endpoints are overall survival (OS), objective response rate (ORR) as assessed by the IRC and disease control rate (DCR) as assessed by the IRC.
