MIRA Pharmaceuticals has revealed new preclinical data for Ketamir-2, its novel oral ketamine analog being investigated for neurological and neuropsychiatric disorders. The studies show Ketamir-2 acts as a selective inhibitor of the NMDA receptor's PCP-binding site, with 30-50-fold lower affinity compared to ketamine, potentially reducing side effects like dissociation and hallucinations.Unlike traditional ketamine, Ketamir-2 demonstrates unique selectivity by not interacting with opioid receptors, dopamine and serotonin transporters, or acetylcholine receptors. Toxicology studies in rats and dogs have shown no toxicity at high doses, with antidepressant and anxiolytic activities observed at 5-10 times lower doses.The company plans to submit an Investigational New Drug Application to the FDA later this year. The selective binding mechanism and improved safety profile suggest potential advantages in treating depression, treatment-resistant depression, and PTSD with reduced side effects and better therapeutic outcomes.

MIRA製藥公司披露了其新型口服氯胺酮類藥物Ketamir-2的最新臨牀前數據,該藥物正在研究用於神經和神經精神疾病。研究表明,Ketamir-2作爲NMDA受體的PCP結合位點的選擇性抑制劑,其結合親和力比氯胺酮低30-50倍,可能減少如解離和幻覺等副作用。與傳統氯胺酮不同,Ketamir-2展示了獨特的選擇性,不與阿片受體、多巴胺和5-羥色胺轉運體或乙酰膽鹼受體相互作用。大鼠和狗的毒理學研究表明,在高劑量下沒有毒性,在5-10倍較低劑量下觀察到抗抑鬱和抗焦慮活性。公司計劃於今年晚些時候向FDA提交新藥研究申請。選擇性結合機制和改善的安全性表明,在治療抑鬱症、難治性抑鬱症和創傷後應激障礙方面,可能具有減少副作用和更好治療效果的優勢。
