Alpha Cognition Inc. is a commercial stage, biopharmaceutical company dedicated to developing treatments for patients suffering from neurodegenerative diseases, such as Alzheimer’s disease and Cognitive Impairment with mild Traumatic Brain Injury (“mTBI”), for which there are currently no approved treatment options. ZUNVEYL is a patented drug approved as a new generation acetylcholinesterase inhibitor for the treatment of Alzheimer’s disease, with expected minimal gastrointestinal side effects. ZUNVEYL’s active metabolite is differentiated from donepezil and rivastigmine in that it binds neuronal nicotinic receptors, most notably the alpha-7 subtype, which is known to have a positive effect on cognition. ALPHA-1062 is also being developed in combination with memantine to treat moderate to severe Alzheimer’s dementia, and as an intranasal formulation for Cognitive Impairment with mTBI. For further information: Investor Relations IR@alphacognition.com https://www.alphacognition.com/ INDICATION AND USAGE ZUNVEYL is a cholinesterase inhibitor indicated for the treatment of mild to moderate dementia of the Alzheimer’s type in adults. IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS ZUNVEYL is contraindicated in patients with known hypersensitivity to benzgalantamine, galantamine, or to any inactive ingredients in ZUNVEYL. Serious skin reactions have occurred. WARNINGS AND PRECAUTIONS Serious Skin Reactions: Serious skin reactions (Stevens-Johnson syndrome and acute generalized exanthematous pustulosis) have been reported in patients receiving galantamine (the active metabolite of ZUNVEYL tablets). If signs or symptoms suggest a serious skin reaction, use of this drug should not be resumed, and alternative therapy should be considered. Anesthesia: See Drug Interactions Section Cardiovascular Conditions: Cholinesterase inhibitors, including ZUNVEYL, have vagotonic effects on the sinoatrial and atrioventricular nodes, leading to bradycardia and AV block. Bradycardia and all types of heart block have been reported in patients taking cholinesterase inhibitors, both with and without known underlying cardiac conduction abnormalities. Therefore, all patients should be considered at risk for adverse effects on cardiac conduction. Patients treated with galantamine up to 24 mg/day using the recommended dosing schedule showed a dose-related increase in risk of syncope. Gastrointestinal Conditions: Cholinesterase inhibitors, including ZUNVEYL, may increase gastric acid secretion. Patients should be monitored closely for active or occult gastrointestinal bleeding, especially those with a history of ulcer disease or those receiving concurrent nonsteroidal anti-inflammatory drugs (NSAIDs). Clinical studies of galantamine have shown no increase, relative to placebo, in the incidence of either peptic ulcer disease or gastrointestinal bleeding. Galantamine has been shown to produce nausea, vomiting, diarrhea, anorexia, and weight loss. Monitor the patient's weight during therapy with ZUNVEYL. Genitourinary Conditions: Although this was not observed in clinical trials with galantamine, cholinesterase inhibitors, including ZUNVEYL, may cause bladder outflow obstruction. Neurological Conditions: Cholinesterase inhibitors are believed to have some potential to cause generalized convulsions. Seizure activity may also be a manifestation of Alzheimer's disease. Patients with Alzheimer's disease should be monitored closely for seizures while taking ZUNVEYL. Pulmonary Conditions: Cholinesterase inhibitors, including ZUNVEYL, should be prescribed with care to patients with a history of severe asthma or obstructive pulmonary disease. Monitor for respiratory adverse reactions. ADVERSE REACTIONS The most common adverse reactions with galantamine tablets (≥5%) were nausea, vomiting, diarrhea, dizziness, headache, and decreased appetite. DRUG INTERACTIONS Use with Anticholinergics: Galantamine has the potential to interfere with the activity of anticholinergic medications. Use with Cholinomimetics and Other Cholinesterase Inhibitors: A synergistic effect is expected when cholinesterase inhibitors are given concurrently with succinylcholine, other cholinesterase inhibitors, similar neuromuscular blocking agents or cholinergic agonists such as bethanechol. USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data may cause fetal harm. Hepatic Impairment: In patients with moderate hepatic impairment, a decrease in clearance of galantamine was observed; therefore, a dosage adjustment is recommended. Use of ZUNVEYL in patients with severe hepatic impairment is not recommended. Renal Impairment: In patients with a creatinine clearance of 9 to 59 mL/min, an increase in exposure of galantamine was observed; therefore, a dosage adjustment is recommended. Use of ZUNVEYL in patients with creatinine clearance less than 9 mL/min is not recommended. These are not all of the possible side effects of ZUNVEYL. You can report side effects to the FDA.
