DelveInsight’s “Rabies Infection – Pipeline Insight, 2025” showcases a growing portfolio of candidates targeting both pre- and post-symptomatic stages. Recombinant monoclonal antibody cocktails are being developed as scalable, safer alternatives to RIG, offering consistent potency and reduced cold chain dependency. Next-generation vaccines—including vector-based, nucleic acid–based (mRNA, DNA), and intradermal dose-sparing formulations—are advancing in clinical and late preclinical stages to enhance immunogenicity, durability, and accessibility in endemic regions. Antiviral platforms, including RNA polymerase inhibitors and virus-neutralizing peptides, are under investigation to extend the therapeutic window after exposure and potentially treat early symptomatic rabies.
The 2025 rabies pipeline reflects a strategic shift toward globally deployable, precision-targeted prevention and treatment modalities. With growing global health prioritization, regulatory encouragement for innovative biologics, and increased funding from public-private partnerships, the next wave of rabies research holds promise to bridge the gap between prevention and cure—moving beyond reactive care toward durable, universal protection.

• In May 2025, npj Vaccines published an observational clinical study (n=159) showing a favorable safety profile for the docaravimab/miromavimab monoclonal antibody cocktail (TwinRab) used in severe animal bites for rabies PEP, with no rabies cases over 6 months of follow-up (published May 21, 2025).
• In July 2024, npj Vaccines reported multi-species efficacy data for a non-replicating mRNA rabies vaccine protecting dogs, rodents, and macaques—supporting continued clinical development (published July 20, 2024).
Rabies Infection Overview
Rabies infection is a viral disease caused by the rabies virus, primarily transmitted through the bite or scratch of an infected animal. It affects the central nervous system, leading to inflammation of the brain (encephalitis) and, if untreated, is almost always fatal. Early symptoms include fever, headache, and general weakness, progressing to more severe signs such as anxiety, confusion, paralysis, and hydrophobia (fear of water). The virus travels from the entry site to the brain via the peripheral nerves, making timely post-exposure prophylaxis (PEP) critical to preventing disease onset. Rabies remains a significant public health concern worldwide, especially in regions with limited access to vaccines and healthcare.
Prevention of rabies primarily involves vaccination of domestic animals, wildlife control, and prompt administration of rabies vaccines and immunoglobulins after potential exposure. Current treatments include various rabies vaccines, such as purified vero rabies vaccine and novel candidates like SYN023 and PIKA rabies vaccine, which are designed to enhance immune response and improve protection. Despite advances in vaccine development, rabies continues to cause thousands of deaths annually, emphasizing the need for increased awareness, vaccination programs, and access to medical care.

Rabies Infection Treatment Analysis: Drug Profile
SYN-023: Synermore Biologics
SYN-023, developed by Synermore Biologics, is a combination of two humanized monoclonal antibodies, CTB-011 and CTB-012, that target two distinct antigenic sites on the rabies glycoprotein. Intended for post-exposure prophylaxis in humans alongside the rabies vaccine, SYN-023 works by binding to the rabies virus and neutralizing it, mimicking the natural immune response. It has demonstrated the ability to neutralize over 15 contemporary rabies virus isolates from wildlife in China and 10 isolates from North America. Currently, SYN-023 is in Phase III clinical trials for the treatment of rabies infection.
Freeze-dried human rabies vaccine: Anhui Zhifei Longcom Biopharmaceutical
The freeze-dried human rabies vaccine, developed by Anhui Zhifei Longcom Biopharmaceutical, utilizes Vero cells and is also in Phase III development for rabies treatment.
