Figure 1: Effect of TOTUM•854 supplementation on systolic (SBP) and diastolic (DBP) blood pressure after 3 weeks, in an induced hypertension model (L-NAME model). After 3 weeks, L-NAME induced a 24 mmHg-raise in SBP and a 19 mmHg- raise in DPB (grey bars). Supplementation with TOTUM•854 (blue bars) significantly reduced SBP by 16 mmHg (p<0.01) and DBP by 15 mmHg (p<0.05). (Graphic: Business Wire)

VALBIOTIS (FR0013254851 – ALVAL, PEA-SME eligible) (Paris:ALVAL), a Research & Development company committed to scientific innovation for preventing and combating metabolic diseases, announces the presentation of positive preclinical results of TOTUM•854 in hypertension at the joint meeting of the European Society of Hypertension (ESH) and the International Society of Hypertension (ISH) held from April 11 to 14, 2021, in virtual format.

This research, conducted on two different in vivo models, shows that TOTUM•854 prevents hypertension.
Based on this positive data, Valbiotis is stepping up its development of TOTUM•854 and will launch three clinical studies at the end of this year, including a Phase II/III clinical study for reduction of hypertension, a risk factor for cardiovascular disease.
TOTUM•854 could be commercialized at the end of this study, up to 3 years ahead of schedule, in partnership with a major healthcare player.

Pascal SIRVENT, Member of the Board and Head of Discovery, Preclinical and Translational Research at Valbiotis, said: “We are proud of this first selection at a major international congress in the cardiovascular field, for which Valbiotis has partnered with the University of Avignon. The TOTUM•854 data collected from two different models of hypertension is remarkable, it validates our hypotheses and our approach to this condition. This very strong proof-of-concept for prevention of hypertension points to ambitious clinical development for TOTUM•854.”

The work presented at the ESH-ISH Joint Meeting was conducted on a model of hypertension induced by L-NAME (a NO synthase inhibitor). In this classic model of hypertension, predictive of human physiology, TOTUM•854 prevented the onset of hypertension compared with the control group. Additional data, obtained from a polygenic model of hypertension (SHR, spontaneously hypertensive rats), also shows a positive effect of TOTUM•854 that delays the onset of hypertension. In addition, a significant acute effect was observed following a single dose of TOTUM•854 on the same SHR model.

Table 1: Effect of a single oral dose of TOTUM•854 in a polygenic model of hypertension (SHR model) on systolic (SBP) and diastolic (DBP) blood pressure, during 24 hours. Starting the experiment (« baseline »), SBP (164 mmHg) and DBP (115 mmHg) were typical of an installed hypertension. Oral intake of a TOTUM•854 dose led to blood pressure reduction, resulting in a decrease of both SBP and DBP Areas Under the Curve (AUC), over a 24h-record compared to the control group.

These results stem in particular from a program carried out under a partnership between Valbiotis and the experimental unit of the Cardiovascular Pharm-Ecology Lab (LaPEC) of the University of Avignon, directed by Cyril REBOUL, PhD, expert in cardiovascular pharmacology.

Cyril REBOUL, PhD, head of the experimental unit of the Cardiovascular Pharm-Ecology Lab (LaPEC) of the University of Avignon, said: “Through our work, we have shown a preventive effect of TOTUM•854 on the development of hypertension in a recognized preclinical model using the L-NAME inhibitor. Undeniably, these results constitute quite an achievement at this stage of TOTUM•854’s development. We are very pleased to have been able to contribute our expertise as part of this fruitful partnership with Valbiotis.”

Acceleration of the development for commercialization now scheduled for 2023

Based on these results, Valbiotis has revised its clinical development program for TOTUM•854 with the launch of a Phase II/III study, the last step before a health claim application in Europe and the United States for reduction of blood pressure, a risk factor for cardiovascular disease. This international, multicenter, randomized, placebo-controlled study will be conducted in a population of 600 volunteers with mild to moderately elevated blood pressure. The study will involve three groups: a TOTUM•854 group at a dose of 3.75 g/day, a TOTUM•854 group at a dose of 2.5 g/day and a placebo group. Its primary endpoint will be the reduction of systolic blood pressure in the TOTUM•854 group (3.75 g/day) after 6 months of supplementation versus the placebo group. It will also evaluate the effect of a reduced dose of TOTUM•854 (2.5 g/day) on blood pressure. In addition, 24-hour ambulatory blood pressure measurements will be taken as a secondary endpoint of the study. The protocol is expected to be filed with the authorities in the fourth quarter of 2021, with results anticipated in the second half of 2023.
A second international, multicenter, randomized, placebo-controlled clinical study will be conducted in parallel at a dose of 3.75 g/day of TOTUM•854. This strategy will allow Valbiotis to prepare a complete health claim application.
Finally, Valbiotis will conduct a third clinical study to measure the bioavailability of TOTUM•854, characterize its metabolites and explore their mode of action.

Murielle CAZAUBIEL, Member of the Board, Head of Development and Medical Affairs at Valbiotis, said: “These preclinical results raise great hopes for the clinical development of TOTUM•854 in the prevention of hypertension. That’s why we are accelerating our strategy for this active substance. Hypertension is considered the foremost chronic disease in the world by the World Health Organization. It’s a serious risk factor for cardiovascular disease, in particular strokes. TOTUM•854 could quickly become an extremely interesting non-drug alternative for people at risk, whether or not they are already taking treatment. This plant-derived active substance would ultimately be developed in the form of capsules or powder for dilution.”

The new strategic development plan will leverage the potential of TOTUM•854 in preventing hypertension, with the aim of bringing it to market as soon as the Phase II/III study ends, in other words by 2023.

Market data on mild to moderate hypertension: conquering an addressable market of over one billion euros

In 2020, AEC Partners conducted a mild to moderate hypertension market study in the United States and 5 main European countries (Germany, Spain, France, Italy and the United Kingdom).
It highlights the size of this market in these regions, which alone represents 124 million people with moderately elevated blood pressure.

Sébastien PELTIER, CEO and Chairman of the Board, said: “In the US and 5 main European countries (Germany, Spain, France, Italy and the United Kingdom), our target represents 124 million people with mild to moderately high blood pressure. TOTUM•854 will give us access to a huge market worth over €1.15 billion. We are now embarking on a new cycle with the development of TOTUM•854 for prevention of hypertension. By accelerating our strategy, we will gain 3 years on our development plan, with a possible market launch on completion of the Phase II/III study. I am confident that we will achieve growth and create value for our shareholders over the long term, turning our innovations into products that can transform the lives of millions by addressing as yet unmet medical needs.”

Tigo Energy Demonstrates Optimization to Installers in Brazil with Stark Renováveis Installation7.5.2021 02:14:00 CEST | Press release

Tigo Energy, Inc., the solar industry’s leading Flex MLPE (Module Level Power Electronics) supplier, announced today that Stark Renováveis has used the Tigo TS4-A-O to mitigate energy lost due to shade on their corporate headquarters in São José do Rio Preto, Brazil. Their confidence in Tigo’s solution drove the selection of the products for their own use. The Tigo solution gives installers and commercial system owners the freedom to choose their preferred inverters and panels along with the right features for optimized, monitored and PV safe systems. The Stark Renováveis team chose a rooftop PV system with 405 Wp modules organized in multiple strings and using GoodWeTM grid-tied inverters. The optimum placement of the modules was on a roof bordering a large construction wall which would ordinarily lead to shade and a degradation of the output. To mitigate the problem of energy lost due to shade, Tigo TS4-A-O optimizers were deployed to ensure the best possible system performance. "As
