REHOVOT, Israel and FORT LEE, N.J., Aug. 19, 2020 (GLOBE NEWSWIRE) — Kamada Ltd. (NASDAQ & TASE: KMDA) and Kedrion Biopharma, two leading biopharmaceutical companies specialized in plasma-derived protein therapeutics, today announced results from a U.S. post-marketing pediatric trial of KEDRAB® (Rabies Immune Globulin [Human]). The study represents the first and only trial of a currently available human rabies immune globulin (HRIG) conducted in children in the U.S. to date. The results have been submitted to the U.S. Food and Drug Administration for review and inclusion as pediatric data in the KEDRAB full prescribing information. KEDRAB is a human rabies immunoglobulin (HRIG) indicated for passive, transient post-exposure prophylaxis (PEP) treatment of rabies infection, when given promptly after contact with a rabid or possibly rabid animal.
The KEDRAB U.S. Pediatric Trial was conducted at two sites, one in Arkansas and another in Rhode Island. The study included 30 pediatric patients (ages 0-17 years old), each of whom received KEDRAB as part of PEP treatment following exposure or suspected exposure to an animal suspected or confirmed to be rabid, and safety follow-up was conducted for up to 84 days. The primary objective of the study was to confirm the safety of KEDRAB in the pediatric population. Secondary objectives included the evaluation of antibody levels and the efficacy of KEDRAB in the prevention of rabies disease when administered with a rabies vaccine according to the PEP recommended guidelines.
No serious adverse events were observed during the study. No incidence of rabies disease or deaths were recorded throughout the 84-day study period.
“These key study results represent the first clinical trial data in the U.S. pediatric population for any HRIG currently available in the US,” said Michal Stein, M.D., Vice President, Medical Director (Immunology) at Kamada. “According to the World Health Organization, 40 percent of people bitten by suspected rabid animals are children under 15 years of age. Despite the large proportion of pediatric cases, limited safety and efficacy data from clinical trials currently exist for this population. Meeting the primary study objective of KEDRAB in children further strengthens our ongoing confidence in the product. We continue to believe that sales of KEDRAB has the potential to continue growing in the U.S., capturing a significant share of the estimated annual $150 million U.S. HRIG market.”
“We know the incidence of kids being exposed to animals that may transmit rabies is high in the U.S. and abroad,” said Novinyo Amega, M.D., Head of U.S. Medical Affairs at Kedrion Biopharma. “However, little data exist that can help clinicians better understand the safety profiles of the various HRIG products currently available. Therefore, we are pleased to see that top-line results of this pediatric study support KEDRAB’s safety profile. Importantly, we believe that meeting the primary objective of this study could further differentiate KEDRAB from other currently available HRIGs in the U.S.”
KEDRAB was launched in the U.S. in April 2018 and generated in-market sales of $31 million in 2019, representing approximately 20 percent of the U.S. HRIG market.
KEDRAB [Rabies Immune Globulin (Human)] is a human rabies immunoglobulin (HRIG) indicated for passive, transient post-exposure prophylaxis (PEP) of rabies infection, when given promptly after contact with a rabid or possibly rabid animal. KEDRAB should be administered concurrently with a full course of rabies vaccine.
Important Safety Information
- Patients who can document previous complete rabies pre-exposure prophylaxis or complete post-exposure prophylaxis should only receive a booster rabies vaccine without KEDRAB, because KEDRAB may interfere with the anamnestic response to the vaccine.
- KEDRAB should not be injected into a blood vessel because of the risk of severe allergic or hypersensitivity reactions, including anaphylactic shock.
- Patients with a history of prior systemic allergic reactions following administration of human immune globulin preparations should be monitored for hypersensitivity.
- KEDRAB contains a small quantity of IgA. Patients who are deficient in IgA have the potential to develop IgA antibodies and may have anaphylactic reactions following administration of blood components containing IgA.
- KEDRAB administration may interfere with the development of an immune response to live attenuated virus vaccines.
- KEDRAB is derived from human plasma; therefore, the potential exists that KEDRAB administration may transmit infectious agents.
- In clinical trials, the most common adverse reactions in subjects treated with KEDRAB were injection site pain, headache, muscle pain, and upper respiratory tract infection.
- Please see KEDRAB Full Prescribing Information for complete prescribing details.
Rabies is a preventable viral disease of mammals most often transmitted through the bite of a rabid animal. It is a serious, and nearly always fatal, infection. In the U.S., rabies in wild animals, especially raccoons, skunks, foxes and bats, accounts for most cases of rabies passed on to humans, pets, and other domestic animals. An acute, progressive viral encephalomyelitis, rabies carries the highest case fatality rate of any conventional etiological agent. Rabies is one of the oldest described infectious diseases, known for over 5,000 years.
