Rivus Pharmaceuticals, a biopharma firm targeted on therapies for cardiometabolic well being, announced positive data from their Part IIa scientific trial Wednesday morning. Rivus’s experimental drug, HU6, confirmed important fats discount and weight reduction in sufferers combating weight problems. The success fee was important, however the distinctive means during which the sufferers misplaced weight was what made this scientific trial stand out.
The Charlottesville, Virginia-based firm was based with the mission to create managed metabolic accelerators, a brand new class of medicines that deal with the underlying metabolic causes of kind 2 diabetes, HFpEF and NASH, together with different cardiovascular and metabolic illnesses.
These medicines increase sufferers’ metabolisms to assist them burn fats. The drug, HU6, was examined in a double-blind, placebo-controlled trial of 80 individuals, all of whom had a physique mass index between 28 and 45 with an elevated liver fats of at the very least 8%. Sufferers obtained doses of 150 mg, 300 mg, 450 mg, or a placebo. Strikingly, statistically important weight reduction and liver fats discount had been seen throughout all dosage teams—with no adjustments to food regimen or train.

The first differentiator right here is that the burden loss got here completely from fats loss, with no lack of lean muscle mass. Moreover, the fats loss was even higher in sufferers who had been extra overweight. In an interview with BioSpace, Rivus Chief Govt Officer Allen Cunningham and Chief Scientific Officer Shaharyar Khan, Ph.D., defined the importance of that discovering.
“No different mechanism has been in a position to selectively goal fats loss as an alternative of muscle loss. When different weight reduction therapies induce a caloric deficit, plenty of the burden loss in most sufferers is lean muscle mass. Wherever from 20 to 60% of the burden loss is skeletal muscle and lean physique mass, however that’s not what we see with this scientific trial. We see strictly fats loss. And in sufferers who had particularly elevated A1C ranges [high blood glucose levels], we see even higher fats loss,” Khan stated.

The truth that the drug confirmed elevated profit with extraordinarily overweight sufferers is spectacular. The sufferers who battle most with weight problems could also be at some extent the place food regimen and train just isn’t a fast sufficient resolution.
“Many of those sufferers are exercise-intolerant. It’s tougher to realize fats loss when you will have a metabolic dysfunction or diabetes or elevated HbA1c [blood hemoglobin and glucose] ranges,” Cunningham defined. “The sufferers is probably not able to addressing the basis explanation for their weight problems illness. This HU6 drug works with the metabolism to assist them get them to some extent the place they can train as a result of they’re at a more healthy weight.”
As a result of the research topics strictly misplaced fats, with out dropping muscle mass, they noticed enhancements in different areas of their well being.
“We’re additionally seeing decrease glycemic indexes on this research. About 40% of the sufferers within the research had elevated A1C, that means they had been diabetic or pre-diabetic. We’re seeing enhancements in glycemic management, important reductions in liver fats, histological enhancements, and reductions in high-sensitivity CRP, which is a marker of systemic irritation and cardiovascular threat—all whereas preserving muscle mass,” Khan stated. “We’re watching this drug assist individuals not solely do higher however really feel higher.”
This scientific trial was additionally distinctive due to the give attention to security. Each Cunningham and Khan made it clear within the interview that security had been a precedence throughout all planning and execution phases of the research – and that security confirmed within the outcomes. There have been no critical opposed occasions reported in the course of the research. Additionally, the drug confirmed wonderful tolerability.
Going ahead, the Rivus group is worked up for the potential that HU6 holds for weak sufferers combating weight problems. They’re additionally intrigued by the information the research has provided into understanding how and why HU6 is so efficient.
“The thrilling factor about this Part II information is that it offers us visibility into the consequences that we’ll see by indication and by dose in metabolic illnesses. One factor that has been actually useful from this research is our understanding of how this drug works and our skill to pick out the right dosage. That is the groundwork for additional scientific improvement that shall be required for particular indications,” Cunningham shared.
As Rivus continues innovating, it plans to carry a Part IIb scientific trial completely in sufferers with kind 2 diabetes. The corporate additionally plans to file for an Investigational New Drug (IDE) software for HU6 with the U.S. Meals and Drug Administration’s Division of Cardiology and Nephrology in Q1 2022.
