(NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system, today announced topline data for the BREAKOUT study. The BREAKOUT study is a Phase IIb, Multicenter, Open-Label, Prospective Study of BREmelanotide in DiAbetic Kidney Disease to Assess the Efficacy in Reducing Urinary PrOtein and Maintaining Podocyte Density and FUncTion.\n\n  \n\nThe BREAKOUT Study (BMT-701) enrolled 16 patients with confirmed Type 2 diabetic nephropathy and >1000 mg/gm UP/Cr ratio, with 8 patients completing the six-month treatment regimen, at multiple sites in the United States. Patients were administered bremelanotide subcutaneously twice daily, in addition to their maximum tolerated dose of renin-angiotensin-aldosterone system (RAAS) inhibition therapy and monitored through a follow-up period.\nThe study showed that bremelanotide therapy for six months, in patients with established Type II diabetic nephropathy, resulted in positive and beneficial results for the majority of patients related to worsening kidney function and disease progression. Clinically meaningful endpoints included; 71% of patients achieved a >30% reduction in the urine protein to creatinine ratio (UP/Cr), 71% of patients achieved improved or stabilized estimated glomerular filtration rate (eGFR), increased urinary vascular endothelial growth factor (VEGF) levels in 37.5% of patients and reduced urinary synaptopodin losses in 36% of patients.\n\"The data from this trial is encouraging and validates that modulating the melanocortin system could potentially be a new therapeutic strategy and possibly disease-modifying treatment option for people living with this progressive kidney disease,\" said Carl Spana, Ph.D., President and CEO of Palatin. \"Targeting the melanocortin system in autoimmune and inflammation conditions reduces cellular stress, resolves inflammation and promotes tissue repair. Our melanocortin pipeline has demonstrated preclinical efficacy in over 10 disease models, including positive clinical results in this Phase IIb Diabetic Nephropathy study and our MELODY-1 Phase 3 dry eye disease trial earlier this year. Lastly, patient enrollment in our Phase 2 ulcerative colitis trial is complete, with topline data targeted for release in the first quarter of calendar year 2025.\"\n\"The findings from this study are consistent with previous studies that the activation of melanocortin receptors can result in positive effects on kidney function by positively effecting synaptopodin and podocyte function,\" said James A. Tumlin MD, CEO and Founder of NephroNet Clinical Trials Consortium. \"With diabetic nephropathy being one of the leading causes of end-stage renal disease across the world, this positive data supports the further development of a melanocortin agonist like bremelanotide, without melanocortin-2 receptor agonism, as a potential treatment option for diabetic nephropathy patients.\"\nBremelanotide was well tolerated. There were no serious adverse events attributable to bremelanotide treatment. The most common adverse event was skin hyperpigmentation, which occurred in 71% of patients. Additional trial information, including inclusion and exclusion criteria, can be found at https://clinicaltrials.gov via the identifier NCT05709444.\nDiabetic nephropathy (DN), a severe microvascular complication of diabetes mellitus (DM), is the most common form of chronic kidney disease (CKD) and a leading cause of renal failure in end-stage renal disease. No currently available treatment can achieve complete cure.\nDN is a chronic complication of diabetes and the leading cause of end-stage kidney disease, a specific microvascular disease that is the main cause of death in Type 1 DM (T1DM).1,2 In Type 2 DM (T2DM), DN greatly increases mortality and disability in patients with diabetes, and its degree of malignancy is second only to that of cardiovascular disease.3 Recent data has indicated that approximately 9% of the world's adult population is affected by DN, and the prevalence of DN is nearly 70% in patients with diabetes; 592 million people have been predicted to have diabetes worldwide by the year 2035.4–6 As many as 47.66% of patients with diabetes have been estimated to have DN, thus posing a major challenge in treating DM. DN is also the primary cause of kidney failure in patients with diabetes.7\nAbout Melanocortin Receptor AgonistsThe melanocortin receptor (\"MCR\") system has effects on inflammation, immune system responses, metabolism, food intake, and sexual function. There are five melanocortin receptors, MC1R through MC5R. Modulation of these receptors, through use of receptor-specific agonists, which activate receptor function, or receptor-specific antagonists, which block receptor function, can have medically significant pharmacological effects.\nMany tissues and immune cells located in the eye (and other places, for example the gut and kidney) express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation.\nAbout Diabetic (Nephropathy) Kidney DiseaseDiabetic nephropathy (DN) is the most common cause of end-stage renal disease in the United States and other developed countries. Approximately 30 million US patients have chronic kidney disease (CKD) secondary to the combination of hypertension and Type II diabetes mellitus. Despite this remarkable prevalence, clinicians have little consensus on what comprises optimal therapy. While the widespread use of RAAS blockade and other maneuvers have slowed disease progression, approximately one-third of patients with Type II diabetic nephropathy will progress to end-stage renal disease (ESRD). As a result, much effort has been devoted to understanding the mechanisms by which the diabetic condition leads to the typical histopathologic changes, including mesangial expansion, thickened basement membranes, and loss of podocyte density and functionality.\nThere is evidence that injury to the glomerular podocyte is central to the pathogenesis of diabetic nephropathy and that clinical treatments should be directed toward maintaining podocyte viability. Podocytes are highly differentiated neuron-like cells with limited cell division and replacement capacity. They are central to the support and maintenance of glomerular capillary networks and function as the final barrier in glomerular filtration. Evidence from pre-clinical animal model studies suggests that podocyte losses precede and contribute to progressive diabetic glomerulopathy.\nAbout Melanocortins and Kidney DiseaseMelanocortin receptors comprise a complex system comprised of 5 different receptors with broad and varying physiologic functions. MC1r signals through a G-protein coupled pathway that leads to activation of adenylate cyclase and ultimately stimulation of the serine-threonine kinase activity of protein kinase A. A growing body of work in cell signaling and function of the glomerular podocyte suggests that protein kinase A regulates the formation of footplate processes, cell attachment, and apoptosis. MC1r activation may stabilize podocyte function and survival in diabetes and other conditions of glomerular diseases.\nAbout PalatinPalatin is a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor systems, with targeted, receptor-specific product candidates for the treatment of diseases with significant unmet medical need and commercial potential.
