Emmaus Life Sciences Reports Positive Top-Line Preliminary Results in First Patient in Diverticulosis Pilot Trial

January 29, 2020

Torrance CA, January 29, 2020 - Emmaus Life Sciences, Inc. (OTCQB: EMMA), a leader in sickle cell disease treatment, announced today the top-line preliminary results in the first patient in the company’s Pilot/Phase 1 study in the treatment of diverticulosis. The study is utilizing the same pharmaceutical-grade L-glutamine (PGLG) oral powder used in Endari® to evaluate the change in the number, shape and size of colonic diverticula and assess safety. The first patient had a colonoscopy at the start of the study and another colonoscopy after six months of taking 15 grams of PGLG twice a day.

While the results in the first patient are preliminary only, the Principal Investigator (PI) observed “A  marginal but decreased size in some of the diverticula compared to the baseline.” The PI also added that, “In addition, there appears to be smoothing of the edges at the opening of the diverticula compared to the baseline, suggestive of a healing process.”

Clinically, the patient reported improvement in overall condition. Prior to starting the PGLG trial, the patient experienced severe constipation alternating with diarrhea. Six months into the trial, the patient’s bowel movements are now normal and the patient reports feeling better overall.

Dr. Yutaka Niihara, M.D., M.P.H., Chairman and Chief Executive Officer of Emmaus commented, “The initial findings are consistent with the anecdotal discovery and report which formed the basis of our hypothesis on PGLG’s efficacy for diverticulosis. We need to emphasize that this is top-line data on the first patient at an interim examination. However, we are cautiously optimistic as there has never been a treatment that has been reported to reverse diverticulosis.”

Emmaus has issued patents in the U.S., Japan, Australia, Mexico, China, Indonesia, Korea, Russia and India related to compositions, including PGLG, and methods of administration of PGLG for the treatment of diverticulosis.

About Diverticulosis
Diverticulosis, or the presence of colonic diverticula (i.e., pouches in the colon wall), is very common in industrialized nations, with its prevalence increasing with age. An estimated 40% of 60 year-olds and 70% of 80 year-olds in the U.S. have diverticulosis. Of these patients, 10% to 25% can be expected to develop diverticulitis, the advancement of peridiverticular inflammation and infection, resulting in abdominal pain, nausea, vomiting, constipation, diarrhea, fever and leukocytosis (i.e., abnormally high white bold cell count).

About Sickle Cell Disease
Sickle cell disease is an inherited blood disorder characterized by the production of an altered form of hemoglobin which polymerizes and becomes fibrous, causing red blood cells to become rigid and change form so that they appear sickle shaped instead of soft and rounded.  Patients with sickle cell disease suffer from debilitating episodes of sickle cell crises, which occur when the rigid, adhesive and inflexible red blood cells occlude blood vessels.  Sickle cell crises cause excruciating pain as a result of insufficient oxygen being delivered to tissue, referred to as tissue ischemia, and inflammation.  These events may lead to organ damage, stroke, pulmonary complications, skin ulceration, infection and a variety of other adverse outcomes.  Sickle cell disease is a significant unmet medical need, affecting approximately one hundred thousand patients in the U.S. and millions worldwide, the majority of which are of African descent.   An estimated 1-in-365 African American children are born with sickle cell disease.
