Andre Bessette, CEO & Co-founder at Eclipse Regenesis talked about Short Bowel Syndrome at an event by Bio2DeviceGroup (www.bio2devicegroup.org) held at Wilson Sonsini (WSGR) in Palo Alto. Bessette shared information on prevalence of the disease, it’s impact, and the new technology that offers hope for restoration.

Movement of the food
Typically digestion begins in the mouth where chewing and saliva begin to break down the food. As it passes through the esophagus, the contractions in the esophagus moves the food forward towards the stomach. In the stomach, the food breaks down further into liquid or paste and is mixed with acids and enzymes. The stomach slowly empties the contents, called chyme, into the small intestine.
It is the tube shaped organ and is located between the stomach and large intestine. The small intestine is regarded as the workhorse of the digestive system. It is 20 FEET LONG and includes the duodenum, jejunum, and ileum.
Duodenum is the first part of the small intestine where typically iron and other minerals are absorbed.
Jejunum is the middle section where cabs, proteins, fat and most vitamins are absorbed.
Ileum is the lower end of the small intestine where bile acids and vitamin B12 are absorbed.
From small intestine the food travels to the large intestine which is about 5 feet long in adults and helps in absorption of water and other remaining nutrients. It then changes waste from liquid to a solid matter called stool.
Short Bowel Syndrome (SBS)
Short Bowel Syndrome or SBS is a devastating condition where the small intestine is simply too short. The inadequate length of the small intestine leads to a whole host of problems primarily related to malabsorption of nutrients and depending on the degree of shortness, sometimes it drastically shortens lifespan. Typically SBS is diagnosed when people have at least half of their small intestine removed and sometimes all or part of their large intestine removed due to disease or injury and significant damage of the small intestine. Sometimes it is a congenital abnormality, where a baby is born with very short small intestine. Depending on the length, SBS may be mild, moderate or severe.
People with SBS cannot absorb enough water, vitamins, minerals, protein, fat, calories and other nutrients from food. Difficulty in absorbing nutrients depends upon the area of small intestine that is removed or non-existent. This inability to absorb nutrients and water causes severe and frequent diarrhea, weight loss and other symptoms related to loss of essential vitamins and minerals.
There are about 8 thousand new cases of SBS in the US, each year. About 65% of them are due to congenital or acquired defect. Typically pediatric patients die before they reach 3 years of age. Their short life is marked with TPN (Total Parenteral Nutrition) treatment where by nutrients are given directly into the bloodstream bypassing the gastrointestinal tract. Gattex (teduglutide) is a prescription medicine given through intravenous (IV) feeding or subcutaneous injection. Not only is it a costly treatment, averaging around 200-300K annually without much improvement but a baby would need to continuously be wearing or accompanying a backpack. Surgical treatment costs 150K to 400K and transplants cost over a million dollars and require life long care, possibility of rejection and infections and has about 5 year mortality for 50% of patients. NONE OF THE CURRENT TREATMENT OPTIONS RESTORE FULL BOWEL FUNCTION.
Eclipse Regenesis Solution
The Eclipse XL1 therapy is a restorative solution designed to grow a longer, healthy intestine rapidly in the course of 2-3 weeks. The solution is entirely mechanical and repeatable, without any harmful or toxic effects. Eclipse has devised a nitinol coil that is introduced into the small intestine via a stoma. Plication sutures are then applied outside the intestine to hold it in place. During the course of the therapy of 2-3 weeks, while the device is in place, nutrients continue to flow through the intestine. Over 2-3 weeks period, the coil gradually expands. As it expands, it gently pulls the small intestine, stimulating new tissue growth and lengthening the treated region 2 to 3 times. The solution is striking in its simplicity and beautiful uncomplicated. After expansion, the sutures dissolve, allowing the coil to move forward and finally get passed out naturally.
Besssette shared information on the team of co-founders with impressive credentials and answered various questions from the audience. Yes, the contractile function continues in the newly lengthened intestine, no the length sustains and does not snap back and the process is repeatable to produce clinical significant length of the intestine and all of these is indicated by the animal trials.
Small Bowel Syndrome is an orphan disease and as such the Eclipse XL1 has received a HUD designation (which requires incidence rate of less than 8000 new cases a year, in the US). Eclipse is anticipating using the HDE regulatory pathway which requires safety and probable benefit data. Eclipse plans to commercialize in pediatric market, in the near future.
