Will taking IV CN-105 reduce the chance of experiencing Postoperative Delirium during surgery?
Postoperative delirium is a common complication after surgery, especially in older adults. CN-105 is an experimental drug that mimics a protein involved in brain health. A phase 2 clinical trial tested whether giving IV CN-105 before and after surgery could lower the chance of delirium. The trial found that CN-105 was safe and well-tolerated, but it did not significantly reduce the overall rate of delirium compared to placebo. More research is needed to know if CN-105 can help prevent delirium.
What the research says
A phase 2 randomized clinical trial tested three different doses of IV CN-105 (0.1, 0.5, or 1 mg/kg) in adults aged 60 and older having noncardiac or nonintracranial surgery 5. The drug was started within 1 hour before surgery and given every 6 hours afterward for up to 13 doses 5. The main goal was to check safety and feasibility, not to prove that CN-105 reduces delirium 5. The trial found that CN-105 was safe, with fewer grade 2 or higher adverse events than placebo 5. However, the study was not large enough to show a clear effect on delirium rates 5. Other research has identified many risk factors for postoperative delirium, such as older age, male sex, alcohol use, smoking, insomnia, and poor nutrition 34. Preoperative psychological factors like depression and anxiety may also play a role 2. These factors were not specifically addressed in the CN-105 trial. The evidence for CN-105 is still early, and no large studies have confirmed it reduces delirium.
What to ask your doctor
- What is my personal risk for postoperative delirium based on my age, health, and type of surgery?
- Are there any proven ways to lower my risk of delirium, such as avoiding certain medications or optimizing nutrition?
- Is CN-105 available for my surgery, or is it only used in research studies?
- What are the signs of delirium I should watch for after surgery, and when should I call you?
- Can you review my current medications and health conditions to see if any increase my delirium risk?
