NCT06432166

Brief Summary

Investigators propose a phase 1b/2a, randomized, double-blind, placebo-controlled, parallel group dose finding and biomarker study to evaluate the safety, tolerability, and biomarker activity of 2-HOBA in 48 MCI/AD participants. Participants will be randomized 1:1:1:1 to receive 250 mg BID, 250 and 500 mg 2-HOBA acetate TID or placebo for 12 weeks. Blood and cerebral spinal fluid (CSF) will be collected to measure markers of protein modification by dicarbonyls (IsoLGs- \& MDA), pTau-181, YKL-40, and NF-L.

    Change in CSF levels of the dilysyl-malondialdehyde crosslink and the lysyl-levuglandin adduct of CSF proteins in a dose-responsive relationship

    Baseline to week 12

Secondary Outcomes (6)

  • Compliance

    Baseline to week 12

  • Measurement of biomarker, p-Tau181

    Baseline to week 12

  • Measurement biomarker, human cartilage glycoprotein 39 (YKL-4)

    Baseline to week 12

  • Measurment of biomarker, neurofilaments light chain protein (NF-L)

    Baseline to week 12

  • Measurement of biomarker, F2-Isoprostanes

    Baseline to week 12

  • +1 more secondary outcomes

Other Outcomes (3)

  • Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)

    Baseline to Week 12

  • Activities of Daily Living (ADL)

  • Clinical Dementia Rating (CDR)32 Global = 0.5. Memory Box score must be at least 0.5
  • Mild AD:
  • Male or female, aged 55-85 years (both inclusive) at the time of signing informed consent.
  • MCI or Mild dementia of the Alzheimer's type according to the NIA-AA 2018 criteria.
  • CDR global score of 0.5 and CDR domain score of 0.5 or more in at least one of the three instrumental activities of daily living categories (personal care, home \& hobbies, community affairs) Or CDR global score of 1.0

You may not qualify if:

Major depression, bipolar disorder as described in DSM-V within the past 1 year or psychotic features, agitation, or behavioral problems within 3 months, which could lead to difficulty complying with the protocol. 3. History of schizophrenia (DSM V criteria). 4. History of alcohol or substance abuse or dependence within the past 2 years (DSM V criteria). 5. Clinically significant or unstable medical condition, including uncontrolled hypertension, uncontrolled diabetes, or significant cardiac, pulmonary, renal (defined by eGFR score \<60 mL/min/1.73 m²), hepatic impairment, endocrine, or other systemic disease that, in the opinion of the Investigator, may put the participant at risk because of participation in the study, influence the results, or affect the participant's ability to participate in the study.
  • Participants with moderate or severe hepatic impairment, defined as Child-Pugh Class B or C, are excluded. 6. Has had a history within the last 5 years of a primary or recurrent malignant disease with the exception of non-melanoma skin cancers, resected cutaneous squamous cell carcinoma in situ, basal cell carcinoma, cervical carcinoma in situ, or in situ prostate cancer with normal prostate-specific antigen post-treatment. 7.
