Clinical Research Trials

Memory Center Clinical Research Trials

Hattiesburg Clinic Memory Center conducts clinical trials that focus on neurological therapeutics, with Alzheimer’s disease being an area of special interest and expertise. Basic research techniques generate ideas about which medical strategies may be likely to help alleviate symptoms of an illness or disease. Clinical research protocols are then developed in order to test these hypotheses.

Clinical trials are designed to determine if a new treatment will be both safe and effective for patients. In addition, trials will often collect data to determine whether an investigational strategy will have a broader influence on related problems such as activities of daily living, caregiver stress or general quality of life.

Clinical trials in Alzheimer’s disease will usually involve both patients and caregivers. While trial participation is completely voluntary, it is important to recognize the time and effort involved in the successful completion of a clinical trial.

Hattiesburg Clinic Memory Center is gratified to be able to offer our community access to potential new treatments for Alzheimer’s. New treatments can only be discovered through the partnership of patient volunteers, research sites, and scientific sponsors. Everyone plays an important role in this investigational process. Every day, we work with hopeful optimism towards more effective therapies, more accurate diagnoses, and eventually a sustainable cure for Alzheimer’s disease.

None of this happens without your help.

Currently Enrolling Trials

Alector – Invoke (AL002-2) NCT04592874

  • This is a phase 2 randomized, double blind, placebo controlled study evaluating the efficacy and safety of AL002 administered intravenously in participants with Early Alzheimer’s Disease.

Avanir – Aspect (20-AVP-786-036) NCT04408755

  • This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786 (deudextromethorphan hydrobromide [d6-DM]/quinidine sulfate [Q]) compared to placebo for the treatment of agitation in participants with dementia of the Alzheimer’s type.
  • Eligible participants for this study must have a diagnosis of probable Alzheimer’s disease (AD) and must have clinically significant, moderate/severe agitation secondary to AD. This is a multicenter, randomized, double-blind, placebo-controlled study, consisting of 12 weeks of treatment.

ENVISION (221AD305) NCT05310071

  • The primary objective of this study is to verify the clinical benefit of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score as compared with placebo in participants with early Alzheimer’s disease.

evoke / evoke+ (NN6535-4730/4725) NCT04777396 and NCT04777409

  • This study is done to find out whether the medicine, semaglutide, has a positive effect on early Alzheimer’s disease. Participants will either get semaglutide or placebo (a “dummy” medicine which does not contain any study medicine) – which treatment participants get is decided by an equal chance. The study will last for up to 173 weeks (about 3 years and 4 months).

Janssen – Autonomy (63733657ALZ2002) NCT04619420

  • The primary purpose of this study is to evaluate the effect of JNJ-63733657 versus placebo on clinical decline as measured by the Integrated Alzheimer’s Disease Rating Scale (iADRS), a composite of cognition and function.
  • JNJ-63733657 is a humanized monoclonal anti-tau antibody which binds to phosphorylated tau (P-tau). The study will evaluate whether JNJ-63733657 can slow clinical (cognitive and functional) decline in participants with Early AD with evidence of elevated brain tau (T+) and assess its safety and tolerability. The study consists of: screening period (13 weeks), double-blind treatment period (up to 232 weeks), and a follow-up period (13 weeks).

New IDEAS: Imaging Dementia-Evidence for Amyloid Scanning Study NCT04426539

  • New IDEAS is an observational, open-label, longitudinal cohort study designed to address the requirements of the CED provisions of the NCD on beta-amyloid PET. Building on the initial Imaging Dementia-Evidence for Amyloid Scanning (IDEAS) study, New IDEAS will evaluate the association between amyloid PET and patient-centered outcomes in an expanded and more ethnoracially and clinically diverse group of Medicare participants presenting with cognitive impairment.

Active Non-Enrolling Trials

Clarity AD (BAN2401-G000-301) NCT03887455

  • This study will be conducted to evaluate the efficacy of BAN2401 in participants with early Alzheimer’s disease (EAD) by determining the superiority of BAN2401 compared with placebo on the change from baseline in the Clinical Dementia Rating-Sum of Boxes (CDR-SB) at 18 months of treatment in the Core Study. This study will also evaluate the long-term safety and tolerability of BAN2401 in participants with EAD in the Extension Phase and whether the long-term effects of BAN2401 as measured by the CDR-SB at the end of the Core Study is maintained over time in the Extension Phase.

EMBARK (221AD304) NCT04241068

  • Phase 3b Open-Label, Multicenter, Safety Study of BIIB037 (Aducanumab) in Subjects With Alzheimer’s Disease Who Had Previously Participated in the Aducanumab Studies 221AD103, 221AD301, 221AD302 and 221AD205

H8A-US-B004 (GERAS-US) Identifier: NCT02951598

  • The purpose of this study is to learn about health care use, costs, and clinical outcomes over time for amyloid positive participants with early stages of AD in the United States. This study is for research purposes only, and is not intended to treat any medical condition. No study therapy(ies) for AD will be administered.
