The company says that by demonstrating Ketamir-2's robust safety profile in comprehensive preclinical studies, MIRA has significantly de-risked this critical aspect of drug development.
该公司表示,通过在全面的临床前研究中证明Ketamir-2的强大安全性,MIRA显著降低了药物开发这一关键方面的风险。
This milestone positions the company for a smoother regulatory pathway, potentially increasing the likelihood of successful clinical outcomes.
这一里程碑使公司走上了更顺畅的监管途径,有可能增加取得成功临床结果的可能性。
Highlights of Preclinical Findings:
临床前发现要点:
- Cardiovascular Safety in Dogs: No adverse effects were noted at therapeutic doses.
- CNS Assessment in Rats: No significant CNS changes were observed at therapeutic dose levels, confirming a favorable safety profile. Effects in high-dose groups were limited, transient, and non-disruptive.
- Respiratory Safety in Rats: No respiratory-related effects were noted across all tested doses.
- 14-Day Toxicology in Dogs: Ketamir-2 was well-tolerated at daily doses up to 200 mg/kg, with no observed adverse effects. This dose established the No Observed Adverse Effect Level (NOAEL).
- Ames Test: Ketamir-2 was confirmed to be non-mutagenic, further supporting its safety profile.
- 狗的心血管安全:在治疗剂量下未发现任何不良反应。
- 大鼠中枢神经系统评估:在治疗剂量水平上未观察到显著的中枢神经系统变化,证实了良好的安全性。对高剂量组的影响有限、短暂且无干扰性。
- 大鼠的呼吸安全:在所有测试剂量中均未发现与呼吸道相关的影响。
- 狗的14天毒理学:每日剂量高达200 mg/kg时,Ketamir-2的耐受性良好,未观察到不良反应。该剂量确定了未观察到的不良反应水平(NOAEL)。
- 艾姆斯测试:Ketamir-2被证实是非诱变性的,这进一步支持了其安全性。
The Phase 1 trial, set to begin in the first quarter of 2025, is designed to gather critical insights into the safety, tolerability, pharmacokinetics, and pharmacodynamics of Ketamir-2 in healthy subjects.
1期试验定于2025年第一季度开始,旨在收集有关Ketamir-2在健康受试者中的安全性、耐受性、药代动力学和药效学的关键见解。
The trial will include a robust battery of pain tests to evaluate the drug's effects on neuropathic pain and psychosis.
该试验将包括一系列强大的疼痛测试,以评估该药物对神经病理性疼痛和精神病的影响。
These evaluations are expected to provide data by Q2 2025, helping to understand how Ketamir-2 affects pain in humans prior to initiating Phase 2a trials in patients.
这些评估预计将在2025年第二季度提供数据,有助于在启动针对患者的2a期试验之前了解Ketamir-2如何影响人类疼痛。
Building on the Phase 1 findings, MIRA plans to initiate a Phase 2a proof-of-concept study in Q4 2025, focusing on patients with neuropathic pain. Proof-of-concept results are anticipated by year-end 2025.
在第一阶段研究结果的基础上,MIRA计划在2025年第四季度启动一项2a期概念验证研究,重点关注神经病理性疼痛患者。概念验证结果预计将在2025年年底公布。
Price Action: At last check on Tuesday, MIRA stock was down 1.63% to $1.21 during the premarket session.
价格走势:在周二的最后一次检查中,MIRA股价在盘前交易时段下跌了1.63%,至1.21美元。
