Abstract
Background Multiple Sclerosis (MS) is the first cause of non-traumatic neurological disability in young adults. Primary and secondary progressive MS are still lacking effective treatments. A new nutraceutical product made of lyophilised leaves of bioengineered kiwi plants (Actinidia deliciosa) overexpressing osmotin has recently been developed. Osmotin is a protein associated with stress adaptation in plant cells and it shares anti-inflammatory and neuroprotective properties with mammalian adiponectin. The aim of this study is to explore the safety and the efficacy of osmotin in progressive MS (PMS).Methods This is a prospective, multicenter, single-arm interventional, baseline vs treatment study that will be carried out by two Italian MS centers, where a total of fifty PMS patients will be recruited. Every patient will take a daily dosage of 5 grams of an osmotin-based nutraceutical, named Forza (TM) (9th Dimension Biotech, Inc.), for 6 months. Two pre-treatment assessments, at -6 months (-6M) and at baseline visit (M0), and two post-treatment assessments, at month 1 (M1), and at month 6 (M6) will be carried out. ForzaTM safety and activity, assessed by serum Neurofilaments Light (NfL) Chain quantification, are the primary outcomes of the study. Additional assessments will consist of clinical and neuropsychological evaluations, patient reported outcomes (PROs), brain magnetic resonance imaging (MRI), motor evoked potentials (MEPs) and optical coherence tomography (OCT).Discussion Disease modifying treatments in MS usually target inflammatory pathways with excellent results on reducing relapse associated disability but fail in preventing progression independent from relapse activity.
