NESS ZIONA, Israel I December 23, 2015 I Kamada Ltd. (NASDAQ:KMDA) (TASE:KMDA), a plasma-derived protein therapeutics company focused on orphan indications, reports that the pivotal Phase 2/3 clinical trial with the Company’s human rabies immune globulin (IgG or KamRAB™ or KedRAB™) therapy as a post-exposure treatment for rabies successfully met the trial’s primary endpoint of non-inferiority when measured against an IgG reference product. The Company expects to file a Biologics License Application (BLA) with the U.S. Food and Drug Administration (FDA) in mid-2016.
KamRAB is the brand name for Kamada’s human rabies immune globulin currently marketed for this indication in 10 countries worldwide. Kamada has a strategic agreement with Kedrion S.p.A for the clinical development and marketing of its IgG product, which will be branded as KedRAB in the U.S., subject to receiving marketing approval from the FDA.
The Phase 2/3 clinical trial was a prospective, randomized, double-blind, non-inferiority study of 118 healthy subjects. The study evaluated pharmacokinetic (PK) parameters of anti-rabies IgG levels in serum at different time points and assessed whether Kamada’s IgG interferes with the development of self-active antibodies. In addition, safety and tolerability were assessed. The trial’s primary end point measured the anti-rabies titer on day 14 as well as on additional time points for secondary end points, following drug infusion and infusion of an active vaccine as recommended by the standard-of-care. The primary endpoint was designed to determine non-inferiority with a -10% margin. Detailed information about this study is available at www.clinicaltrials.gov.
Top-line results showed that the primary endpoint of non-inferiority was met with a difference of -1.8% between the two therapies with variability between -8.2% and 3.1% (90% Confidence limit). Results showed that Kamada’s IgG was safe and well tolerated with no drug-related Serious Adverse Events (SAEs) experienced.
“The post-prophylaxis treatment has proven critical for this fatal rabies disease. We are delighted to report the positive data, which show our IgG product achieved its primary endpoint of non-inferiority in this pivotal trial and demonstrated that our IgG product doesn’t interfere with the development of self-active antibodies,” commented Dr. Eran Schenker, V.P.- Medical Director of Kamada.
“Since 2003 we have marketed KamRAB in 10 countries outside the U.S. and we have sold more than one million vials to date, which provides significant experience with this product. We are confident our product will provide a much-needed, high-quality source of IgG for people who are at risk of being exposed to rabies. Consequently, we have confidence that our product will be competitive with the current reference IgG product in providing the needed protection,” said Amir London, Chief Executive Officer of Kamada. “The WHO estimates that approximately 10 million people worldwide require medical treatment against rabies each year after being exposed to an animal suspected of rabies infection. We believe that a competitive product in the U.S. will provide diversity of supply in a market with ample room for a new product entry while improving Kamada profitability with higher margins expected in the US compared to rest of the world countries. We plan on leveraging the U.S. trial and future marketing approval to expand our global market leadership with this critical medical treatment.”
“We are very excited about the commercial potential for KedRAB in the U.S., where there are approximately 40,000 post-exposure prophylaxis treatments administrated each year, representing a more than $100 million annual market opportunity. With one predominant rabies prophylaxis provider in the U.S., we anticipate that healthcare professionals will want to diversify their source of supply, particularly if a competing high-quality product, such as KedRAB, is approved for use. We look forward to a favorable regulatory outcome and, in time, a successful product launch,” stated Larry Guiheen, Kedrion’s Chief Commercial Officer.
About KamRAB/KedRAB
Rabies is a preventable viral disease of mammals most often transmitted through exposure to a rabid animal. KamRAB/KedRAB is a prophylactic treatment against rabies infection that is administered to patients after exposure to an animal suspected of being infected with rabies. KamRAB/KedRAB is a protein therapeutic derived from hyper-immune plasma, which is plasma that contains high levels of antibodies from donors that have been previously exposed to rabies. KamRAB/KedRAB is administered via a one-time injection, with the precise dosage being a function of the patient’s weight.
