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 (TASE:) 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.
