Healthcare Industry News: seasonal allergic rhinitis
News Release - May 31, 2007
Cobalis Announces Delay in Reporting of Phase III Trial Results for PreHistin(TM) in Seasonal Allergic RhinitisIRVINE, Calif.--(HSMN NewsFeed)--Cobalis Corp. (OTCBB:CLSC ), a pharmaceutical development company specializing in anti-allergy medications, today announced that it is concerned about apparent inconsistencies in the databases of the Phase III clinical trials for its drug PreHistin(TM). Accordingly, it will delay release of the trial results until an audit of the trial data and procedures is completed.
The Company said its concerns included the possibility of incorrect data entry in patient-symptom diaries. Given inconsistencies it has identified, the Company does not know at this time which data are correct, and it said it must review source documents and conduct other quality control measures as part of its audit. Cobalis said the audit will also include an examination of the consistency of data collection methods in both studies.
"It is frustrating, of course, that we cannot report a clear-cut result for the Phase III trials of PreHistin at this time," said Gerald J. Yakatan, Ph.D., Chief Executive Officer. "However, there appear to be enough inconsistencies to warrant a thorough review before we can reliably report PreHistin's efficacy, or lack thereof. In the meanwhile, we appreciate our shareholders' support and patience as the Company works through these issues."
The parallel, randomized, double-blind Phase III Clinical Trials involved 1,551 patients at 23 sites across the central, southern and eastern U.S. The patients received either a placebo or a 3.3-mg sublingual dosage of PreHistin twice daily for three weeks prior to the onset of the ragweed allergy season and for an additional three weeks into the allergy season. The primary efficacy parameter for each trial was the difference in the mean reduction in Total Nasal Symptom Score (TNSS) observed between the placebo and PreHistin over the fourth, fifth and sixth weeks of the studies. TNSS is a 12-point scale derived by summing and averaging all a.m. and p.m. scores for four symptoms: sneezing, runny nose, nasal congestion and nasal itch. Each symptom is given a score -- 0 (none), 1 (mild), 2 (moderate) or 3 (severe) -- resulting in a maximum recorded TNSS of 12. Patients maintained electronic diaries twice daily, self-rating their average symptoms over the previous 12 hours.
About seasonal allergic rhinitis
seasonal allergic rhinitis, otherwise known as hay fever, is an allergic reaction to airborne substances such as pollen that get into the upper respiratory passages and cause the body to produce antibodies and release histamine. Histamine makes the upper respiratory swell and produce typical allergy symptoms such as sneezing, runny nose and nasal congestion. In the U.S. approximately 40 million people suffer from seasonal allergic rhinitis with related healthcare costs exceeding $7 billion annually. Ragweed is the single most common seasonal allergen, affecting up to 75% of those with seasonal allergic rhinitis, or 30 million Americans. Current treatment options are mainly limited to symptomatic therapies to provide temporary relief and conventional allergy immunotherapy by injection. PreHistin is a unique molecule, unrelated to anti-histamines. PreHistin is believed to be a safe, non-sedating novel approach to pre-seasonal allergy treatment targeted for OTC distribution.
PreHistin is a sublingual lozenge that delivers its active ingredient through the buccal membrane directly into the bloodstream. The active ingredient, cyanocobalamin, has a well-known safety profile and has been shown in studies to relieve symptoms related to seasonal allergies, asthma and other atopic allergic diseases. PreHistin may represent a novel approach to treatment by rectifying imbalances in the immune system that trigger the over-production of allergy symptom-causing substances including histamines. By preventing or reducing the over-production of these substances before they are released from cells, the need to block the symptom-causing effects of histamine may be eliminated, or minimized. PreHistin is patented for the treatment of atopic allergic diseases such as seasonal and perennial allergies, dermatitis, migraine, food allergies and asthma.
