Palatin Technologies Inc. has announced preclinical results for PL-7737, an oral selective melanocortin MC4 receptor (MC4R) agonist, showing effectiveness in rodent models of obesity.

Launched out of 5AM Ventures’ 4:59 Initiative, Renasant Bio Inc. has secured $54.5 million in seed funding to support development of treatments for autosomal dominant polycystic kidney disease (ADPKD), a genetic disease caused by mutations in the PKD1 and PKD2 genes, which encode polycystin proteins PC1 and PC2 that come together to form a calcium ion channel vital for kidney function.

Polycystic ovary syndrome is a common endocrine disorder in women of reproductive age and characterized by obesity, insulin resistance and renal injury.

GIPR/GLP-1R-targeting agents have demonstrated significant efficacy in appetite suppression and weight reduction; however, their adverse effect profiles and tolerability issues highlight the need for alternative or complementary therapeutic strategies in the management of obesity. Researchers from Juvena Therapeutics Inc. reported on the preclinical profile of JUV-112, discovered using Juvena’s proprietary JuvNET platform.

Manufacturing issues are the latest problem for Ultragenyx Pharmaceutical Inc. to solve after last week’s disappointment in a phase III study to treat brittle bones. The U.S. FDA gave the company a complete response letter (CRL) regarding the BLA for its gene therapy to treat Sanfilippo syndrome type A, saying it needs more details and improvements made about CMC after having finished manufacturing facility inspections.

Diabetic retinopathy (DR) is a leading cause of vision loss in patients with diabetes, with limited therapeutic options. While current treatments focus on the proliferative stage, there is an urgent need to understand the underlying mechanisms of the early stages of DR to halt progression. Growing research suggests that activated microglia are key drivers of inflammation in DR.

Single agonists of the glucagon-like peptide-1 receptor (GLP-1R) have been a success in the treatment of obesity, but monomeric dual or triple agonists have demonstrated improved efficacy on energy intake, appetite or metabolic function.
