MW150 Stress Kinase Inhibitor in Mild to Moderate Alzheimer's Disease

This study is a phase 2a randomized double-blind, placebo-controlled, study, in mild-to-moderate Alzheimer's disease, of the oral investigational drug MW150, a p38alphaMAPK kinase inhibitor. The primary goals of this study are to investigate the safety and tolerability, and drug movements in the body. The secondary goals of the study are to investigate the effects of the drug on cognitive performance, activities of daily living, and behavior, and the biological effects of the drug on blood biomarkers.

2. Male or female, age 50 to 90 inclusive.
3. Have a study partner who is able to accompany the subject, has frequent contact with subject.

14. If female, must not be of childbearing potential, as defined by being postmenopausal (more than 1 year without periods) or surgically sterile for at least 6 months prior to screening.
15. If male, must agree to use contraception if with a potentially childbearing partner.

Exclusion Criteria:

Presence of clinically significant disorders of the central nervous system other than Alzheimer's disease, such as Lewy Body Disease, Parkinson's disease, hydrocephalus, epilepsy, demyelinating disease, brain tumors, or psychiatric disorders (such as schizophrenia, or severe affective disorders).
2. Serious or unstable hematologic, hepatic, renal, pulmonary, cardiac, or other medical disease.
3. Abnormal liver function tests (ALT or AST) or creatine kinase (CK) upon repeat testing.
4. Chronic hepatitis B or C infection, indicated by positive HBSAg, or HCV-Ab with HCV RNA presence.
5. Known history of human immunodeficiency virus (HIV) infection.
6. Known immune disorder that has a history of requiring treatment with immunosuppressive drugs within the past 1 year.
7. Have a drug or alcohol abuse within 12 months prior to screening.
8. Clinically significant laboratory abnormalities at screening.
9. Screening ECG showing repeated QTcF \> 480 msec, or other clinically significant ECG abnormalities.
10. Clinically significant structural brain abnormalities, such as hydrocephalus or intra-axial brain tumors.
11. Participation in another investigational study within 30 days or 5 half-lives prior to screening, whichever is greater.
12. Participation in another study that would have cognitive testing during the duration of this study.
13. History of Covid19 or other viral infections within 3 months.
14. Have a clinically significant medical, surgical, laboratory, or behavioral abnormality, which in the judgment of the Investigator makes the subject unsuitable for the study.
