Phase II Clinical Trial for Pancreatic Cancer Planned for Q2 2023
Fremont, CA - (NewMediaWire) - August 22, 2022 - ABVC BioPharma, Inc. (NASDAQ: ABVC), a clinical stage biopharmaceutical company developing therapeutic solutions in oncology/hematology, CNS, and ophthalmology, today provided an update on its development of oncology medicines for the treatment pancreatic cancer (ABV-1703), non-small cell lung cancer (ABV-1519), triple negative breast cancer (ABV-1501) and myelodysplastic syndrome (ABV-1702). The Company expects to initiate the first Phase II clinical trials for ABV-1703 in the second quarter of 2023 by Dr. Andrew E. Hendifar at the Cedars-Sinai Medical Center in Los Angeles, California.
Early Studies of the Maitake Mushroom
The medicines developed by ABVC for oncology disorders are based on research conducted in Asia over the past 25 years, as well as a Phase I/II dose escalation trial performed in 2017 at the Memorial Sloan Kettering Cancer Center (“MSKCC”) in New York to determine the therapeutic effects of an ingredient (BLEX 404) derived from the Maitake mushroom.
Researchers in Asia and the United States have demonstrated that this mushroom, which is widely popular in China, has the following effects:
Enhances natural killer (NK) cell activity, as well as macrophage and cytotoxic T cell functions
Increases B cell/antibody response
Induces dendritic cell in protection against tumor implantation
Induces cytokines such as interferon-gamma (IFN-γ) from mouse splenocytes, and interleukin-12 (IL-12) in a macrophage line
In addition, experiments conducted in Japan using a mice chemotherapy model demonstrated a reversal of immune suppression and enhancement of bone marrow growth and differentiation were both enhanced.
Memorial Sloan Kettering Studies
In the first MSKCC study, 34 postmenopausal breast cancer patients, enrolled sequentially in five cohorts of 0.1, 0.5, 1.5, 3, or 5 mg/kg BID for 3 weeks, became free of the disease after initial treatment. There was no dose-limiting toxicity observed in any of the patients, while both immunologically stimulatory and inhibitory measurable effects in collected peripheral blood from patients were detected. Another Phase II trial at MSKCC examined the effects of Maitake on innate immune function in 21 myelodysplastic syndromes (MDS) patients. The patients were administered BLEX 404 Oral Liquid at 3 mg/kg BID for 12 weeks. Results of the study showed that Maitake was well-tolerated, enhancing in vitro neutrophil and monocyte function, illustrating beneficial immunomodulatory in MDS.
In 2016, the ABVC team, including certain affiliates, began to develop a set of oncology medicines by assessing the efficacy and safety of BLEX 404 Oral Liquid combined with certain anti-cancer agent(s). Early testing preliminarily indicated that certain dose levels (RDLs) of BLEX 404 Oral Liquid when combined with current cancer treatment medicines showed promising results for patients.
On August 25, 2017, ABV-1703’s Phase II trial was approved by the U.S. FDA. The trial will be conducted at Cedar Sinai Medical Center as the first of a series of Phase II studies to determine the efficacy and safety of these combined drugs as well as the most effective dose level. While the sites and principal investigators for the Company’s additional oncology medicines have yet to be determined, ABVC anticipates clinical studies for ABV-1519 for non-small cell lung cancer and ABV-1501 for triple negative breast cancer will be initiated in Q3 2023. The clinical study for ABV-1702 for myelodysplastic syndrome is expected to start in Q4 of 2023. The Company plans to submit ABV-1703’s Phase II clinical trial IND to the Taiwan FDA after commencing clinical trials in the United States.
