Deana Simpson and I, as co-chairs of the CJD International Support Alliance (CJDISA), will ask members of the Friends and Advisory group of the CJDISA to provide a lay summary on scientific papers that either you show interest in or we feel may be helpful in understanding the level of research happening around the world on prion disease.



LAY SUMMARY. Granagard is a nano formulation of PSO (pomegranate seed oil). PSO comprises 80-90% of Punicic Acid (omega 5) which is the strongest natural lipid antioxidant. In vivo, Punicic acid metabolizes into a specific form of conjugated linoleic acid (CLA), which is known to be a calpain inhibitor, suggested as a treatment target for several neurodegenerative conditions. While the active components, both PSO and CLA, do not enter the brain following administration of PSO and actually also CLA, following administration of the Granagard formulation, CLA is found in the brain of rodents, concomitantly with its neuroprotective effect that cannot be found when natural PSO was administrated. Most of our prion related experiments were done in a genetic model of E200K CJD. These mice are born heathy, then start to show neurological disabilities at 5-6 month of age and from there deteriorate until a terminal state at about 12 months of age. They mimic the situation of healthy carriers since they present spontaneous disease caused by a mutant PrP. Continuous Granagard administration from birth or 3 months of age delays the presentation of terminal disease in these mice by almost 6 months. The mechanism of activity of Granagard is most probably related to the maintenance of normal mitochondrial activity even under the stress caused by abnormal protein aggregates, thereby allowing neuronal survival under disease. This is applicable to a number of neurodegenerative disease diseases as well as normal aging.
Several human studies are in process (Alzheimer’s disease (AD) ,Parkinson’s disease (PD). Preliminary results in a double-blind study shows that administration of Granagard as compared to placebo improves memory and cognition in MS patients under diverse treatments. As for CJD, we are mostly interested in delay/prevention in asymptomatic carriers of pathological PrP mutations. It is indeed very difficult to establish a proper clinical study to establish if carriers taking Granagard will get sick later or never as compared to those taking placebo. Nobody wants to be in the placebo group for years and most people don’t want to get tested for the mutation. Therefore, we are looking at this in a different manner. Since Granagard is a safe food supplement beneficial to the general public, we follow a large group of genetic families in Israel in which all/most the siblings in affected families are taking it. Then we look, with the help of the medical community in Israel, at the new CJD patients. We believe 30-50% of CJD affected families are taking Granagard regularly.
We have learned so far that
1: No symptomatic CJD patient has taken Granagard prior to diagnosis.
2: The general number of genetic CJD patients, which was around 20 per year for several years until 2017, has gone down to less than 10 in 2018/2019 and may be as low in 2020.
Obviously, this is all observational and more time is needed to establish if we had affected disease onset, but it looks very encouraging.
