Study Endpoints

Primary Endpoints

Part 1: Number of Participants With Adverse Events That Are Related to Treatment With ISIS 814907
From first dose of study drug up to Week 37 in Part 1

An adverse event (AE) was defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of medicinal (investigational) product, whether or not the AE was considered related to the medicinal (investigational) product. A TEAE was defined as any AE that starts or worsens on or after the date of first dose of study treatment. TEAEs were categorised as mild, moderate, and severe to aid in severity assessment.

Part 2: Number of Participants With Adverse Events That Are Related to Treatment With ISIS 814907
From first dose of study drug up to Week 64 in Part 2

An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of medicinal (investigational) product, whether or not the AE was considered related to the medicinal (investigational) product. A TEAE was defined as any AE that starts or worsens on or after the date of first dose of study treatment. TEAEs were categorised as mild, moderate, and severe to aid in severity assessment.

Frequently asked questions about IONIS MAPTRx

What is IONIS MAPTRx used for?

IONIS MAPTRx is an investigational drug being studied for the treatment of mild Alzheimer's disease. It is a small molecule developed by Ionis Pharmaceuticals, Inc. (IONS). The drug is currently in Phase 1 clinical development, meaning it is still being tested in clinical trials and is not yet approved for use.

What does IONIS MAPTRx target?

IONIS MAPTRx is designed to target the production of tau protein, which is associated with Alzheimer's disease pathology. By reducing tau protein levels, the drug aims to address a key component of the disease process. This mechanism is being evaluated in patients with mild Alzheimer's disease.

Who makes IONIS MAPTRx?

IONIS MAPTRx is being developed by Ionis Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol IONS. The company is conducting clinical research to evaluate the safety and efficacy of this investigational drug for mild Alzheimer's disease.

What phase is IONIS MAPTRx in?

IONIS MAPTRx is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The Phase 1 trial has been completed, and the drug is still in the early stages of clinical testing for mild Alzheimer's disease.

What clinical trials is IONIS MAPTRx in?

IONIS MAPTRx has been studied in one completed Phase 1 clinical trial, identified as NCT03186989. This trial evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of the drug in 46 patients with mild Alzheimer's disease. The study was randomized, double-blind, and placebo-controlled, and included participants aged 50 years and older.

Is IONIS MAPTRx the same as IONIS-MAPTRx?

Yes, IONIS MAPTRx is the same drug as IONIS-MAPTRx. The name is sometimes written with a hyphen, but both refer to the same investigational small molecule being developed by Ionis Pharmaceuticals for mild Alzheimer's disease. The clinical trial NCT03186989 uses the name IONIS-MAPTRx.
