Study Endpoints

Primary Endpoints

Number of Participants Experiencing Adverse Events (AEs)
Up to approximately 160 weeks

An adverse event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study.

Stage A: Maximum Observed Serum Concentration (Cmax) for Multiple Ascending Dose of ABBV-916
Up to approximately 24 weeks

Cmax of ABBV-916 will be determined.

Stage A: Time to Cmax (Tmax) for Multiple Ascending Dose of ABBV-916
Up to approximately 24 weeks

Tmax of ABBV-916 will be determined.

Stage A: Apparent Terminal Phase Elimination Rate Constant (β) of ABBV-916
Up to approximately 24 weeks

Apparent terminal phase elimination rate constant (β) of ABBV-916 will be determined.

Stage A: Terminal Phase Elimination Half-Life (t1/2) of ABBV-916
Up to approximately 24 weeks

T1/2 of ABBV-916 will be determined.

Stage A: Trough Serum Concentration (Ctrough) of ABBV-916 at the End of a Dosing Interval
Up to approximately 24 weeks

Ctrough of ABBV-916 will be determined.

Stage A: Area Under the Concentration-Time Curve (AUC) of ABBV-916
Up to approximately 24 weeks

AUC of ABBV-916 will be determined.

Stage A: Cerebrospinal Fluid (CSF) Concentration as a Measure of ABBV-916 Crossing the Blood Brain Barrier
Up to approximately 24 weeks

The central value for ratio of ABBV-916 concentration in cerebrospinal fluid (CSF) to that in serum will be estimated for evaluation of the fraction of ABBV-916 crossing the blood brain barrier.

Stage A: Percentage of Participants With Antidrug Antibodies (ADA) as a Measure of Immunogenicity Following Multiple Ascending Dose of ABBV-916
Up to approximately 24 weeks

Antidrug antibody (ADA) classification and titers for positive ADA samples will be determined.

Stage B: Change in Brain Amyloid Plaque Deposition (Amyloid Centiloid Value)
Baseline (Week 0) through Week 24

Change from baseline in brain amyloid plaque deposition (amyloid centiloid value) is measured by amyloid positron emission tomography (PET) scan.

Frequently asked questions about ABBV-916

What is ABBV-916 used for?

ABBV-916 is an investigational small molecule being developed for the treatment of Alzheimer's Disease (AD). It is designed to be administered intravenously and is being studied in adult participants aged 50 to 90 years with early Alzheimer's Disease.

How does ABBV-916 work?

ABBV-916 is being studied to assess its effect on brain amyloid plaque clearance in participants with early Alzheimer's Disease. The drug is administered intravenously, and its mechanism involves targeting amyloid plaques, which are a hallmark of Alzheimer's pathology.

Who makes ABBV-916?

ABBV-916 is being developed by AbbVie Inc., a biopharmaceutical company traded on the New York Stock Exchange under the ticker symbol ABBV. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational drug.

What phase is ABBV-916 in?

ABBV-916 is currently in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still undergoing clinical trials to assess its safety and effectiveness in treating early Alzheimer's Disease.

What clinical trials is ABBV-916 in?

ABBV-916 has one completed Phase 2 clinical trial, identified as NCT05291234. This study assessed the safety of ABBV-916 and how it moves through the body and affects brain amyloid plaque clearance in 106 adult participants with early Alzheimer's Disease.

Is ABBV-916 the same as any other drug?

ABBV-916 is a unique investigational compound developed by AbbVie Inc. It is not known to be the same as any other marketed drug. It is being studied specifically for its potential to clear amyloid plaques in early Alzheimer's Disease.
