Randomized, Controlled Phase III Clinical Data Demonstrate Generex Oral-lyn's Effectiveness and Non-Inferiority When Compared to Injected Human Insulin
WORCESTER, Mass. and TORONTO, July 10, 2013 /PRNewswire/ -- Generex Biotechnology Corporation (www.generex.com) (OTCBB:GNBT) today announced the results of a Phase 3 clinical trial, conducted by its Indian licensee, Shreya Life Sciences Pvt. Ltd. (www.shreya.co.in), of Generex Oral-lyn , the Company's proprietary buccal insulin spray product, in preparation for the approval for marketing and commercial distribution of the product in India, to be trademarked there as Oral Recosulin .
The trial, entitled "A 12 Week, Open Label, Parallel Group, Comparative, Multi-centric Phase III Study to Assess Efficacy and Safety of Metered Dose Buccal Insulin Spray versus Rapid Insulin, s.c. on Subjects with Type II Diabetes who are inadequately Controlled (i.e. 6.5% less than or equal to HbA1C less than or equal to 8.5%) while on Oral Anti-Diabetic Agents", was conducted at 14 sites in India. Type 2 patients between 18 and 75 years of age with at least one year of use of oral anti-diabetes medications were eligible to participate. Two hundred and nine (209) subjects were randomized to receive either Generex Oral-lyn buccal insulin spray or injected human regular insulin before each major meal as an add-on to the patient's current oral hypoglycemic agent. Dosing was periodically adjusted based on prior fasting blood glucose values. Each subject was instructed in an ADA/IDF (American Diabetes Association/International Diabetes Federation) guidelines dietary plan. One hundred ninety eight subjects (95%) completed the trial.
The hemoglobin A1c (HbA1c) was measured at baseline, 6 weeks and 12 weeks with the following results,
Oral-lyn Buccal Insulin Spray
Regular Insulin Injection
7.44 +/- 1.34
7.47 +/- 1.40
6.96 +/- 1.83
7.42 +/- 1.23
6.99 +/- 1.58
7.24 +/- 0.96
Generex Oral-lyn significantly lowered the HbA1c at 6 weeks and 12 weeks compared to baseline (p less than 0.05) while injected human regular insulin did not significantly lower the HbA1c until 12 weeks. Generex Oral-lyn resulted in a significantly lower HbA1c at 6 weeks than did injected regular insulin (p less than 0.05). At 12 weeks the HbA1c for both groups were statistically comparable.
The results of this Phase III trial show that Generex Oral-lyn more rapidly reduced hemoglobin A1c and was as effective as subcutaneously injected regular insulin at the trial's conclusion establishing non-inferiority. Adverse events were rare and comparable between groups. Generex Oral-lyn was shown to be easily used and well-tolerated by patients, and over two thirds of patients preferred Generex Oral-lyn to injection.
Shreya has advised Generex that the dossier was submitted in December of 2012 to the Drugs Controller General (India) (DCGI), Central Drugs Standard Control Organization, Director General of Health Services, Ministry of Health and Family Welfare, Government of India. Generex has also been advised that Shreya anticipates receiving government approval for the marketing and commercial distribution of the product, known in India as Oral Recosulin , by the end of this year.
The International Diabetes Federation currently estimates there are over 50 million people with diabetes in India. Generex will be working with Shreya as it develops its educational and sales and marketing plans for Oral Recosulin . "This Phase III trial and upcoming approval demonstrate the viability of Generex Oral-lyn as a safe and effective alternative to injected insulin in a large and diverse patient population, and is a significant component in our overall Generex Oral-lyn clinical development strategy," noted Dr. James Anderson, Generex's Senior Scientific Advisor.
Ram Shelat, Shreya's CEO, commented, "We are most pleased with the results of our Phase III study. In anticipation of the DCGI's approval, we have begun working with Generex to facilitate the commercialization of Oral Recosulin in India." Mark Fletcher, President & Chief Executive Officer of Generex, noted, "We are pleased to be working with our partner Shreya as Generex moves forward in the reestablishment of its global Generex Oral-lyn and diabetes programs."

Generex has developed a proprietary platform technology for the delivery of drugs into the human body through the oral cavity (with no deposit in the lungs). The Company's proprietary liquid formulations allow drugs typically administered by injection to be absorbed into the body by the lining of the inner mouth using the Company's proprietary RapidMist device. Antigen Express, Inc. is a wholly owned subsidiary of Generex. The core platform technologies of Antigen Express comprise immunotherapeutic vaccines for the treatment of malignant, infectious, allergic, and autoimmune diseases. Antigen Express has pioneered the use of specific CD4+ T-helper stimulation technologies in immunotherapy. One focuses on modification of peptides with Ii-Key to increase potency while a second relies on inhibition of expression of the Ii protein. Antigen Express scientists, and others, have shown clearly that suppression of expression of the Ii protein in cancer cells allows for potent stimulation of T-helper cells and prevents the further growth of cancer cells.
