Invention Summary:
Metabolically Dysfunctional-Associated Steatotic Liver Disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), is a highly prevalent chronic liver disease, affecting 38% of all adults and up to 14% of children, globally. It is anticipated that by 2040, the MASLD prevalence rate will increase to 55%, worldwide. In the U.S, nearly 86.3 million adults currently have MASLD. MASLD initiates with steatosis (lipid accumulation in the liver), which can then progress to steatohepatitis, fibrosis, cirrhosis and eventual liver failure. MASLD is now a leading cause of liver transplantation. Existing experimental treatments often target late-stage disease or address metabolic factors indirectly, but none have demonstrated rapid, direct reversal of liver pathology. A therapy that can both halt disease progression and actively reverse fibrosis would represent a breakthrough in the field.
Rutgers researchers have developed a novel treatment for targeting all stages of MAFLD (steatosis, steatohepatitis, and fibrosis), namely the modified kisspeptin analog, TAK-448 (MVT-602), originally developed for endocrine disorders. Published studies using several mouse models of MASLD demonstrate that TAK-448 treatment protects against steatosis by inhibiting the synthesis of new fatty acids (de novo lipogenesis), thereby reducing steatosis, liver triglycerides and metabolic dysfunction. TAK-448 treatment improves insulin sensitivity, lowers inflammatory and fibrotic markers, and decreases liver fibrosis. Most strikingly, in human liver slices (hPCLs) from patients with Stage 1, 2, or 4 fibrosis, TAK-448 reversed fibrosis within 72 hours — an unprecedented finding in this disease space. TAK-448 treatment reduced collagen secretion and lowered the expression of markers of fibrogenesis (collagen, smooth muscle actin, fibronectin) and inflammatory markers (interleukin-6, TNFa). Unlike current experimental approaches that primarily slow progression, TAK-448 offers a disease-modifying strategy that intervenes at multiple points in disease biology, combining metabolic improvement, anti-inflammatory action, and rapid fibrosis reversal into a single therapeutic platform.
Market Applications:
Novel therapy for the treatment and prevention of liver steatosis, metabolic dysfunction-associated steatohepatitis (MASH), and liver fibrosis.
First-in-class approach is capable of reversing established human liver fibrosis within 72 hours.
Dual metabolic and anti-fibrotic activity for comprehensive disease modification.
Potential combination partner with existing metabolic or anti-fibrotic agents.
Advantages:
First-in-class mechanism targeting the kisspeptin receptor pathway to directly improve liver metabolism, reduce liver inflammation, and fibrosis.
Safe to administer to humans.
Demonstrated rapid fibrosis reversal in human liver slices from patients with advanced disease (within 72 hours).
Multi-modal therapeutic effects combining anti-steatotic, anti-inflammatory, and anti-fibrotic actions.
Efficacy shown in both prevention and treatment settings in preclinical models and clinically relevant models.
Potential for once-daily subcutaneous administration with a long-acting peptide analog.
Builds on an already clinically tested compound (TAK-448) with existing human safety and pharmacokinetic data.
High selectivity for the kisspeptin receptor pathway minimizes off-target effects common in other MASH drug classes
Compatible with combination therapy strategies without overlapping toxicity profiles
