What is the purpose of this trial?

This trial is testing a new drug called JNJ-63733657 to see if it can help slow down the worsening of symptoms in patients with Alzheimer's disease. The goal is to see if the drug can help maintain brain function and daily living skills better.

Will I have to stop taking my current medications?

The trial requires that any medications affecting the central nervous system (CNS) be stable for at least 2 months before screening, and chronic use of benzodiazepines is not allowed. If you've recently stopped a CNS medication, it must have been discontinued at least 2 months before screening.

What Are the Treatments Tested in This Trial?

Interventions

• JNJ-63733657
• Placebo

Trial Overview The trial is testing JNJ-63733657 against a placebo in slowing down clinical decline in early Alzheimer's patients. The main measure used will be the Integrated Alzheimer's Disease Rating Scale (iADRS), which assesses both cognition and function.

How Is the Trial Designed?

Group I: JNJ-63733657 Low-dose Experimental Treatment 1 Intervention

Participants will receive single dose of JNJ-63733657 low-dose administered by intravenous (IV) infusion every 4 weeks during the double-blind treatment period. Participants will have an option to continue with the long-term extension (LTE) phase of the trial and will continue to receive the same treatment and dose during the LTE treatment period.

Group II: JNJ-63733657 High-dose Experimental Treatment 1 Intervention

Participants will receive single dose of JNJ-63733657 high-dose administered by IV infusion every 4 weeks during double-blind treatment period. Participants will have an option to continue with the LTE phase of the trial and will continue to receive the same treatment and dose during the LTE treatment period.

Group III: Placebo Placebo Group 1 Intervention

Participants will receive single dose of matching placebo to JNJ-63733657 administered by IV infusion every 4 weeks during double-blind treatment period. Participants will have an option to continue with the LTE phase of the trial and will be re-randomized in a 1:1 ratio to receive either JNJ-63733657 low-dose or JNJ-63733657 high-dose during the LTE treatment period.
