A Phase 1 interventional study of ATH-1020 and Placebo in Healthy Volunteers, sponsored by Athira Pharma. Completed at 1 site in United States. Open to participants aged 18 Years to 85 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-04-08.
Sponsored by Athira Pharma · Phase 1, Interventional, and Treatment
This Phase 1 randomized, placebo-controlled, double-blinded, first-in-human study will evaluate safety, tolerability, and pharmacokinetics of single and multiple ascending doses of ATH-1020 in healthy young and elderly subjects.
This is a Phase 1 first-in-human, 2-part adaptive study. Both Part A and Part B will be performed in a randomized, placebo-controlled, and double-blind manner.
Part A - Single Ascending Dose (SAD) Part A will be a SAD study investigating multiple dose levels of ATH 1020.
Part B - Multiple Ascending Dose (MAD) Part B will be a multiple ascending dose (MAD) study investigating multiple dose levels of ATH-1020.
Subjects in Cohort B5 (4 subjects) will additionally undergo CSF sampling pre-dose on Day 4 and up to 3 post dose timepoints to evaluate ATH-1020 blood-brain-barrier penetration

All Subjects
Subjects must have adequate venous access.
Part A (SAD)
Male subjects aged 18 to 50 years at the time of signing the .
Part B (MAD)
Exclusion Criteria:
Major surgery within 90 days prior to Admission (Day -1) or anticipated surgery during the study.
Part A (SAD)
Any medical condition that requires chronic medication use.
Part B (MAD)
Reported changes in cognition and reported history of declines in everyday life in the last year.
Part B (MAD) CSF Sampling (Cohort B5)
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
