PIKA Rabies vaccine(Yisheng Biopharma (Singapore) Pte. Ltd.)

GAITHERSBURG, Md., Nov. 07, 2024 (GLOBE NEWSWIRE) -- LakeShore Biopharma Co., Ltd (Nasdaq: LSB) (“LakeShore Biopharma” or the “Company”), a global leader in the discovery, development, manufacturing, and delivery of next-generation vaccines and therapeutic biologics for infectious diseases and cancer, today announced the initiation of its Biologics License Application (BLA) submission to the Drug Regulatory Authority of Pakistan (DRAP) for the conditional approval of its PIKA rabies vaccine for post-exposure prophylaxis. This submission is based on the results that met the primary endpoints of the vaccine’s global pivotal trial and demonstrated the vaccine’s potential to achieve accelerated protection and meet the WHO’s goal of a one-week rabies vaccine regimen to replace the conventional three- or four-week regimens. Rabies has an almost 100% fatality rate once clinical symptoms appear, leading to approximately 59,000 deaths annually in over 150 countries. More than 95% of rabies fatalities result from bites by infected dogs, with 40% of victims being children under 15. While rabies is typically fatal without treatment, timely post-exposure prophylaxis can effectively prevent death. Pakistan ranks among the top five countries in the world for human rabies prevalence, with over 1.5 million reported dog bites and an estimated 2,000–5,000 human deaths annually. The true impact is likely underestimated due to underreporting. Rabies vaccines remain costly and are often inaccessible in public health sectors. LakeShore Biopharma’s PIKA rabies vaccine could play a pivotal role in addressing this urgently unmet medical need. The PIKA Rabies Vaccine, which utilizes LakeShore Biopharma’s proprietary PIKA adjuvant technology based on Toll-like receptor 3 immunological pathway, is designed to produce a more robust immune response in an accelerated timespan compared to existing rabies vaccines. It was granted orphan drug designation by the US FDA for prevention of rabies virus infection including post-exposure prophylaxis (PEP) for rabies. The pivotal registration Phase 3 Trial was a randomized, comparator-controlled, double-blind, multicenter trial which includes 4,500 participants from the Philippines and Pakistan. It is designed to assess the immunogenicity, safety, and lot-to-lot consistency of three lots of the PIKA Rabies Vaccine in healthy adults using a 7-day vaccine schedule, versus a globally marketed comparator following the standard 28-day regimen. The primary immunogenicity endpoints of the study were geometric mean titers (GMTs) of rabies virus neutralizing antibodies (RVNA) and RVNA seroconversion rate at Day 14 in the first 900 participants. This accelerated and higher seroconversion rate came at no cost to safety, with the safety profile of the PIKA Rabies Vaccine remaining highly tolerable. Dr. Zenaida Mojares, Chief Medical Officer of LakeShore Biopharma, commented, “Our existing rabies vaccine, YSJA, has protected tens of millions of patients in China from this deadly disease. We are committed to advancing next-generation PIKA adjuvanted rabies vaccines to enhance patient protection. The promising results from our pivotal trial validate the potential of PIKA technology to generate a stronger and faster immune response. We remain committed to working closely with drug regulatory agencies in various countries regarding the product registration and marketing application. We eagerly anticipate the early approval of this innovative therapy for the benefit of patients worldwide.” About LakeShore Biopharma LakeShore Biopharma, previously known as YS Biopharma, is a global biopharmaceutical company dedicated to discovering, developing, manufacturing, and delivering new generations of vaccines and therapeutic biologics for infectious diseases and cancer.

Mr. Dave Chenn, Chairman and Interim Chief Executive Officer of the Company, commented, "In Fiscal Year 2024, our revenue was affected by a shortage of finished product inventory, resulting from earlier supply chain disruptions at our YSJA rabies vaccine production facilities. Despite these difficulties, we have successfully implemented operational improvements that have normalized production, and our inventory challenges are now resolved as we enter Fiscal Year 2025. We have maintained our position as a leading rabies vaccine producer in China, and continued to improve our gross margin by emphasizing operational efficiency. We also made significant advancements in our product pipeline during Fiscal Year 2024, progressing our next-generation PIKA rabies vaccine through its ongoing Phase III clinical trial and meeting significant developmental milestones for other pipeline products."

We are implementing a comprehensive plan that includes cost reductions, organizational restructuring, strengthened internal controls, and strategic resource allocation to key growth areas. Our goal will be to foster innovation, efficiency, stability, and sustainable profitability as we work to build value for our shareholders." Ms. Rachel Yu, Interim Chief Financial Officer of the Company, added, "For Fiscal Year 2024, we recorded revenues of RMB573.4 million (US$80.8 million), representing a decrease compared to Fiscal Year 2023 due to persistent supply chain issues affecting raw material availability, manufacturing processes, and overall output capacity which impacted our topline. We recorded a gross profit of RMB455.7 million (US$64.2 million), and our gross margin increased by 1.8 percentage points to 79.5% compared to Fiscal Year 2023. With cash and cash equivalents of RMB246.6 million (US$34.7 million), we will maintain our focus on maximizing long-term shareholder returns by refining our business strategies and leveraging new market opportunities. Looking ahead to Fiscal Year 2025, we anticipate double-digit year-over-year growth in revenues, and expect to achieve breakeven on our bottom line by the time our fiscal year concludes on March 31, 2025." Business Updates YSJATM Rabies Vaccine LakeShore Biopharma's marketed vaccine product, YSJATM rabies vaccine, is the first aluminum-free lyophilized rabies vaccine launched in China. Since the Company commenced production at its current GMP-compliant facilities in February 2020, and commercialization of the product in late 2020, market intake of the Company's YSJA rabies vaccine has been consistent and strong. As of March 31, 2024, LakeShore Biopharma maintained its leadership position as one of the top rabies vaccine producers in China and has sold more than 27.3 million doses of YSJATM rabies vaccines to approximately 1,767 Chinese Center(s) for Disease Control and Prevention ("CDC") customers, which represents 61.3% of CDC customers in China since October 2020. Clinical Pipeline LakeShore Biopharma continues to prioritize and advance its portfolio of innovative product candidates under various clinical development stages, including PIKA rabies vaccine, PIKA YS-ON-001, and PIKA YS-HBV-002. PIKA Rabies Vaccine In April 2024, the Company announced positive interim results from the ongoing Phase III clinical trial of its next-generation PIKA rabies vaccine in the Philippines and Pakistan. The interim results indicate that the PIKA rabies vaccine has successfully met the primary endpoints of the trial and has the potential to achieve best-in-class accelerated protection and meet the World Health Organization's goal of a one-week rabies vaccine regimen to replace the conventional three- or four-week regimens. Subject to successful completion of the Phase III clinical trial, the Company plans to submit the New Drug Applications/Biologics License Applications to relevant regulatory authorities throughout Asia, Africa, Europe, and the Americas. PIKA YS-ON-001 PIKA YS-ON-001 is designed as an immunological therapeutical agent against cancers. In 2023, the Company completed the Phase I clinical trial of PIKA YS-ON-001 in China. PIKA YS-HBV-002 In April 2024, the Company announced that its YS-HBV-002, the second generation of immunotherapeutic vaccine designed to treat patients suffering from chronic hepatitis B virus infection, had been granted clinical trial approval by the Philippine Food and Drug Administration. In light of the approval, the Company is preparing to initiate a Phase I clinical trial for YS-HBV-002 in the Philippines. Fiscal Year 2024 Financial Results Total Revenue Total revenue was RMB573.4 million (US$80.8 million) in Fiscal Year 2024, compared to RMB687.2 million in the same period of 2023, representing a decrease of 16.6%. This was primarily due to COVID-related disruptions affecting the Company's manufacturing operations and production, which reduced batch approvals and doses available for sale. This impact was partially offset by an increase in the product price of the YSJA rabies vaccine of approximately RMB2.9 per dose. Gross Profit Gross profit in Fiscal Year 2024 was RMB455.7 million (US$64.2 million), representing a 79.5% gross margin, compared to RMB533.8 million, or a 77.7% gross margin, in the same period of 2023. The improvement in gross margin was primarily due to the increase in unit price of the YSJA rabies vaccine, and a decrease in unit cost resulting from lowered delivery costs and an increase in production batches. Selling and M arketing Expenses Selling and marketing expenses in Fiscal Year 2024 were RMB301.3 million (US$42.5 million), compared to RMB272.9 million in the same period of 2023. This change was primarily due to an increase in promoting and marketing service fees to continuously promote the YSJA rabies vaccine. General and Administrative Expenses General and administrative expenses in Fiscal Year 2024 were RMB140.1 million (US$19.7 million), compared to RMB72.9 million in the same period of 2023. This change was primarily attributable to increases in legal fees, auditing fees, directors & officers liability insurance costs, and employee benefits. Research and Development Expenses Research and development expenses in Fiscal Year 2024 were RMB302.8 million (US$42.7 million), compared to RMB318.7 million in the same period of 2023. The change was primarily driven by decreases in testing fees, clinical trial fees, and consulting service fees related to the development of the Company's COVID-19 vaccine, and decreases in employee benefits as a result of staffing optimizations. Impairment Loss on Inventory, Property, Plant and Equipment, and Other Assets Impairment loss on inventory, property, plant and equipment ("PP&E"), and other assets in Fiscal Year 2024 was RMB157.4 million (US$22.2 million), compared to RMB8.7 million in the same period of 2023. The change was primarily attributable to 1) impairment loss on inventory impacted by COVID-related disruptions affecting the Company's manufacturing operations and production and raw materials used in the research and development of the Company's COVID-19 vaccine, and 2) impairment loss on PP&E related to COVID-19 vaccine equipment. Net Loss Net loss for Fiscal Year 2024 was RMB433.5 million (US$61.1 million), compared with RMB145.5 million in the same period of 2023. Balance Sheet As of March 31, 2024, the Company had cash and cash equivalents of RMB246.6 million (US$34.7 million), compared with RMB370.4 million as of March 31, 2023. Business Outlook The Company anticipates double-digit year-over-year revenue growth and expects to achieve breakeven in Fiscal Year 2025. The above outlook is based on information available as of the date of this press release and reflects the Company's current and preliminary expectations regarding its business situation and market conditions.
