Brief Summary:
The purpose is to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of IONIS-MAPTRx in patients with Mild Alzheimer's Disease

Condition or disease Intervention/treatment Phase
Mild Alzheimer's Disease Drug: IONIS MAPTRx Other: Placebo Phase 1 Phase 2

Detailed Description:

This is a randomized, double-blind, placebo-controlled study, followed by an Open-Label Extension in up to 44 participants. This study will consist in two parts:

Part 1: a randomized, double-blind, placebo-controlled multiple ascending dose period in participants with Mild Alzheimer's Disease, followed by Part 2: the open-label, long-term extension period.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence and severity of adverse events that are related to treatment with IONIS MAPTRx [ Time Frame: Up to Week 72 of Part 2 ]
    The safety and tolerability of ascending dose-levels of multiple IT bolus administrations of IONIS MAPTRx will be assessed by determining the incidence, severity, and dose relationship of adverse events that are related to treatment with IONIS MAPTRx


Secondary Outcome Measures :
  1. Pharmacokinetics (PK) after ascending dose-levels of multiple IT bolus administrations of IONIS MAPTRx (trough concentration) [ Time Frame: Up to Week 72 of Part 2 ]
    The cerebrospinal fluid (CSF) trough concentrations of IONIS MAPTRx will be assessed after ascending dose-levels of multiple IT bolus administrations of IONIS MAPTRx

  2. Pharmacokinetics (PK) after ascending dose-levels of multiple IT bolus administrations of IONIS MAPTRx (maximum observed drug concentration or Cmax) [ Time Frame: Up to Week 72 of Part 2 ]
    The Plasma pharmacokinetics (maximum observed drug concentration or Cmax)) of IONIS MAPTRx will be assessed after ascending dose-levels of multiple IT bolus administrations of IONIS MAPTRx

  3. Pharmacokinetics after ascending dose-levels of multiple IT bolus administrations on IONIS MAPTRx (time taken to reach maximal concentration or Tmax) [ Time Frame: Up to Week 72 of Part 2 ]
    The plasma pharmacokinetics (time taken to reach maximal concentration or Tmax) of IONIS MAPTRx will be assessed following single and multiple dose IT administration

  4. Pharmacokinetics after ascending dose-levels of multiple IT bolus administrations on IONIS MAPTRx (Plasma terminal elimination half-life (t1/2λz) [ Time Frame: Up to Week 72 of Part 2 ]
    The plasma pharmacokinetics (Plasma terminal elimination half-life (t1/2λz) of IONIS-MAPTRx will be assessed following single and multiple dose IT administration

  5. Pharmacokinetics after ascending dose-levels of multiple IT bolus administrations on IONIS MAPTRx (Partial areas under the plasma concentration-time curve from zero time (predose) to selected times (t) after the IT administration (AUCt) [ Time Frame: Up to Week 72 of Part 2 ]
    The plasma pharmacokinetics (Partial areas under the plasma concentration-time curve from zero time (predose) to selected times (t) after the IT administration (AUCt) of IONIS MAPTRx will be assessed following single and multiple dose IT administration
