PDE5A

MALVERN, Pa., Sept. 30, 2024 (GLOBE NEWSWIRE) -- via IBN – Annovis Bio Inc. (NYSE: ANVS) (“Annovis” or the “Company”), a late-stage clinical drug platform company developing transformative therapies for neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD), today announced the filing of three new patents for innovative combination therapies involving its lead compound, buntanetap. These patents cover combinations of buntanetap with Trulicity (dulaglutide), Viagra (sildenafil), or a combination of all three, creating a multifaceted approach to treating neurodegenerative diseases. Buntanetap, the Company’s lead drug asset, inhibits the production of neurotoxic proteins and has been shown to improve cognition in early AD patients (NCT05686044) and halt cognitive decline in PD patients (NCT05357989). Recent preclinical studies have demonstrated that when buntanetap is combined with a GLP-1 agonist (such as Trulicity) or PDE5 inhibitors (such as Viagra), cognitive function in Alzheimer’s mouse models improves to levels beyond those observed in healthy controls. With these compelling results demonstrating strong potential for cognition-enhancing combinations, Annovis further strengthens its intellectual property portfolio through the filing of the following patents: Buntanetap + Trulicity (dulaglutide, a GLP-1 agonist).Buntanetap + Viagra (sildenafil, a PDE5 inhibitor).Buntanetap + Trulicity + Viagra. “Our early data suggests a strong synergistic effect from combining these drugs, resulting in significant cognitive enhancement,” said Maria Maccecchini, Ph.D., Founder, President, and CEO of Annovis Bio. “The combination of buntanetap with Trulicity and Viagra not only has the potential to restore cognition to healthy levels, but also to improve it beyond normal, offering new hope in the fight against dementia. Since buntanetap has completed Phase 3 studies as a standalone treatment, and both Trulicity and Viagra are FDA-approved, these combinations are well-positioned for Phase 3 human trials.” By leveraging the proven efficacy of Trulicity and Viagra in combination with buntanetap, Annovis is expanding its pipeline and advancing its mission to enhance cognition for those suffering from neurodegenerative disorders. About Annovis Bio, Inc. Headquartered in Malvern, Pennsylvania, Annovis Bio Inc. is dedicated to addressing neurodegeneration in diseases such as AD and PD. The company’s innovative approach targets multiple neurotoxic proteins, aiming to restore brain function and improve the quality of life for patients.

The European Commission has approved Johnson and Johnson’s Yuvanci for pulmonary arterial hypertension, offering the first single-pill treatment option to European patients. Credit: andreswd via Getty Images. The European Commission (EC) has approved Johnson and Johnson’s Yuvanci (macitentan + tadalafil) for the treatment of pulmonary arterial hypertension (PAH). The approval marks Yuvanci as the only single-tablet combination therapy available for patients with PAH. PAH is a rare, progressive disorder in which patients have high blood pressure in the pulmonary arteries for no apparent reason. Current treatment for PAH involves first-line dual combination therapy with macitentan and tadalafil for patients without cardiopulmonary comorbidities. This currently consists of a multi-pill regimen. “This can deeply impact their [PAH patients’] daily lives as they might struggle to maintain adherence to their treatment regimen,” said Dr. Tamara Werner-Kiechle, the Europe, Middle East, and Africa (EMEA) therapeutic area lead for neuroscience and cardiopulmonary drugs at Johnson & Johnson Innovative Medicine in a 30 September press release. Johnson and Johnson has developed the Yuvanci as a substitution therapy for the long-term treatment of PAH in adults of the World Health Organization’s (WHO) Functional Class (FC) II to III. This includes patients with PAH that causes a slight limitation in physical activity, yet they are still comfortable at rest, and “patients with marked limitations to physical activity”, as per WHO. Patients will need to have already been treated with a two-pill combination of macitentan and tadalafil to be eligible for Yuvanci. Johnson and Johnson currently markets macitenan monotherapy under the brand name Opsumit, whilst Eli Lilly sells tadalafil as Cialis for PAH. The approval is based on data from the Phase III A DUE study (NCT03904693) , which also led to a positive recommendation for Yuvanci’s approval by the European Medicines Agency’s (EMA) Committee for Human Medicinal Products in July. The pharmaceutical giant presented data from the Phase III A DUE clinical study at the American College of Cardiology’s 72nd Annual Scientific Session. In the double-blind study, Yuvanci-treated patients showed significant improvements in the co-primary endpoints of pulmonary vascular resistance (PVR) and pulmonary haemodynamic improvement. Patients who took the combination therapy demonstrated a 44% decrease in PVR compared to a 22% decrease in the Adcirca monotherapy group.

Meanwhile, Cialis is a phosphodiesterase type-5 inhibitor that treats the disorder by increasing cGMP, leading to a relaxation of the pulmonary vascular smooth muscle cell and vasodilation of the pulmonary vascular bed. Johnson and Johnson submitted a new drug application to the US Food and Drug Administration (FDA) for Yuvanci in May 2023, receiving an approval for its submission in March 2024.

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. Many 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. About Palatin Palatin 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.
