My sister was diagnosed with Type 1 diabetes when she was in the ninth or tenth grade of high school. She was very active, and even after her diagnosis she served as the captain of the varsity cheerleading squad. She graduated at the top of her class. However, the complications from her disease struck her hard.
Susan battled with bulimia, and hated taking insulin injections. She did not want to be sick, and the needles made her feel her illness even more. I am talking more about a mental weakness. The thought of the needles, and the perception created while injecting insulin at school, did not fit with her attempts to appear perfect. She skipped her injections, manipulated her weight, and only took hold of properly controlling her diabetes when she approached twenty years old.
None of us are perfect, and she made mistakes. Diabetes is a consuming illness to live with, and treat. Juvenile diabetes is tougher for the young, as opposed to Type 2 diabetes, and how it effects an adult. I'm no doctor, so I'll skip explaining why I feel this is the case.
Susan grew into a wonderful and loving woman. She held high ranking jobs at Pepsi, and Disney. Fiercely independent, she moved to Oralando, and thrived. However, her body suffered the consequences of her earlier non-compliance to an insulin regimen. She lost feeling in her feet, and developed tunnel vision. Her kidneys eventually failed, and my father donated his kidney to her in 2001. That kidney has now failed, and she is back on dialysis.
I am fortunate to be a match, and I am donating my kidney to her tomorrow at noon. The surgery takes place at St Barnabas in Livingston. The complications from her diabetes has touched all of us in the family, and it is nothing short of a blessing to help her gain her health and freedom back. I do not want her sentenced to dialysis, since she is still young, and brings happiness to so many. Also, she would do anything for me.
My interest in Generex originated from a deep appreciation for the work they were doing in developing a non-invasive insulin delivery system. RapidMist and Oral-lyn will be their own blessing to juvenile diabetics like Susan, who would be more apt to follow a regimen that was free of needles, and free of the negative perceptions that come with injections.
Oral-lyn was not there to help my sister, but I am. She is always there for me. Oral-lyn will help the next generation, so many of these complications that result from non-compliance, eventually leading to kidney failure, will not occur.

The AE37 Ii-Key synthetic peptide vaccine
Click on image to enlarge. Harvard scientists, who founded and lead Antigen Express, have pioneered and patented technology that modify MHC class II epitope peptides with a fragment of the MHC class II-associated invariant chain. Antigen Express recently reported interim results from a Phase II trial of the AE37 HER2/neu Ii-Key modified peptide vaccine for patients treated for breast cancer who are at high risk of relapse. While there was a 7% relapse rate in the control arm, there were no relapses in the Ii-Key peptide arm (AE37) when analyzed at the 13-month time point. A review article co-authored by Dr. Eric von Hofe, Ph.D., President of Antigen Express, entitled "A New Era in Anticancer Peptide Vaccines", will appear in an early 2010 edition of the journal Cancer, the International Interdisciplinary Journal published by the American Cancer Society. An advantage of using the type of active immunotherapy offered by AE37, as opposed to passive immunotherapy such as treatment with Herceptin, is that activated immune cells can detect and destroy cancer cells expressing much lower levels of HER-2/neu than is needed for recognition by Herceptin.

The Future of Insulin Treatment
Dr Gerald Bernstein, Generex VP and former Pres of the ADA, was featured in an online video at the Doctor's Channel in a segment titled "Diabetes & Endocrinology Oral Insulin Delivery with Oral-Lyn". With many new insulin based drugs on the horizon, Dr Bernstein explains both the history of insulin treatment and what he believes to be the best future option- Oral-lyn. Click on the image of the current new insulin based drugs in development to view the video.
Oral-lyn's time profile; insulin only when a diabetic needs it, bringing less risk of hypoglycemia
This image, which you can click to enlarge, illustrates that with its very fast onset and offset of action, Oral-lyn buccal insulin spray may offer less risk of postprandial hypoglycemia as compared to conventional injected insulin therapy. Hypoglycemia is a life-threatening risk, and along with injections is the most important obstacle towards achieving good metabolic control. With each spray of the RapidMist device one unit of meal time Oral-lyn buccal insulin is said to be rapidly delivered into the bloodstream. The amount of sprays given is determined by the amount of insulin each unique diabetic requires to cover a meal. The company informs that the insulin only remains in the bloodstream during the time period the diabetic needs it, promising a safer and simpler approach.
The extended action of injectables may lead to hypoglycemia; the insulin often lingers too long
In this graph, which you can click to enlarge, we can see the long tail of both meal time analogues and regular insulin. Analogue prandial insulin is dosed approx 15 minutes before a meal, peaks in an hour, and with a duration of effect of 4 hours. Regular insulin is dosed 30 minutes before a meal, peaks in 2 hours and lingers up to 6 hours in the bloodstream. This slow acting tail activity often causes low blood sugar levels to occur after the glucose spike provided by the meal starts to decline. Generex states that Oral-lyn is taken right before the first bite of the meal, immediately begins to be absorbed in the inner lining of the mouth, peaks in 30 minutes, and blood sugar levels cleanly return to baseline within two hours. Generex finds there is no tail of activity with Oral-lyn as there is with all other forms of injectable insulin, so they believe the risk of postprandial hypoglycemia is greatly minimized. If blood levels are back at baseline after the meal, there is no reason to gorge on post meal snacks to offset any lingering insulin, which helps avoid unhealthy weight gain. The unique time action profile for Oral-lyn, if proven in the Phase III study, may provide greater flexibility in usage, as well as the ability to take small dose sprays before a snack when that tasty treat simply can not be resisted. Another main advantage for Oral-lyn may be its ability to mimic the first-phase insulin response seen in a healthy person. This first-phase insulin release is one of the first functions that people with diabetes lose. In healthy people our bodies release insulin within 10 minutes after eating.
Oral-lyn Buccal Insulin X-RAY imagery proves no deposition into the lungs
Unlike Mannkind's Afrezza, in which a powder insulin formulation is inhaled into and absorbed by the lungs, Oral-lyn is delivered as a fine spray to the buccal cavity by the RapidMist delivery system. Generex states the result is rapid insulin absorption through the buccal mucosal lining of the mouth without pulmonary (lung) exposure. The lungs, like all other vital organs in the body, are already a target of diabetes leading to lower lung function over time. The lungs are meant to process gasses, and not proteins. I think that Generex, via Oral-lyn buccal insulin, avoids potential pulmonary complications in a simpler and safer approach. Click on the provided X-Ray image to learn more.
Prandial insulin dosing is now as simple as a spray
Oral-lyn is available in a US FDA approved Treatment IND as well as in Phase III trials as a 1 UNIT per spray dose. For Oral-lyn, the delivery devise appears built to provide fine tuning post meal dosing. It appears as simple as taking another quick spray. In my opinion, as the safety concerns swirl around prospects for inhalable insulin, the Oral-lyn buccal insulin Treatment IND sounds like a great marketing advantage, since more and more diabetics and physicians will learn of buccal insulin as Generex works towards full approval.

Dr Gerald Bernstein, VP Medical Affairs Generex, former President of American Diabetes Association
Click on the photo of Dr Bernstein to view his interview on FOX Health. Dr Bernstein recently commented further on the unique safety profile for Oral-lyn: "It’s extremely safe by all the studies that have been done so far, including two years in animal tests. We haven’t seen allergic reaction. The lining of the mouth hasn’t shown any abnormalities. The buccal mucosa is an extra-tough and resilient tissue, it’s beaten up all the time. People bite themselves or burn themselves. Whatever doesn’t get absorbed is going to go to the stomach. Now the insulin molecule is unprotected and therefore it will be denatured by the acid and then broken down. There are no side effects." Dr Bernstein is an attending physician at Beth Israel Medical Center, and physician emeritus at Lenox Hill Hospital and Montefiore Medical Center, all in New York. He was formerly Director of the Beth Israel Health Care Systems Diabetes Management Program. Dr. Bernstein was president of the American Diabetes Association in 1998-99 and was for many years a member of the ADA's Board of Directors and its Executive Committee. He received the ADA's Banting Medal for Service in 1999. Dr. Bernstein presently serves on several ADA committees and on the Board of Directors of the American Diabetes Association Research Foundation.
