A Study to Evaluate ALN-5288 in Patients With Alzheimer's Disease

To join this study, you would generally need to be between 40 and 80 years old and have a diagnosis of Alzheimer's disease. This diagnosis needs to be supported by special tests, like certain brain scans or checks of your spinal fluid, and confirmed within the last 7 years. You should also have mild memory problems or dementia linked to Alzheimer's.

There are also some important reasons why someone might not be able to join. For example, if your memory problems are caused by a different kind of dementia, or if you have certain health conditions like severe high blood pressure, uncontrolled seizures, or particular heart, liver, or kidney problems. You also wouldn't be able to join if you have certain infections like HIV or hepatitis.

Finally, if you have other serious mental health conditions that aren't well controlled, or if you have problems with your brain or spine that would make injections into that area difficult, you would not be able to participate. The study team will check all these things carefully to make sure it's safe for you to take part.

If you decide to take part in this study, you would receive either the new study medicine, ALN-5288, or a placebo (a dummy medicine with no active drug). This will be given through an injection into the fluid around your spinal cord. The study involves regular visits to the clinic for medical checks, further injections, and to monitor your health and any effects of the medicine. You will have blood tests and other examinations.

The exact number of visits and the full length of your participation would be explained in detail by the study team. They will monitor your health closely throughout the study period. It's important to know that you wouldn't necessarily know whether you are receiving the active drug or the placebo, as this helps ensure the results are accurate and unbiased.
