About this study

Official title: A Phase 1, Randomized, Double-blind, Placebo-controlled, Single and Multiple Ascending Dose Study to Investigate the Safety, Tolerability, and Pharmacokinetics of SNP318 in Healthy Adult Participants

SNP318 is developed to treat neurodegenerative diseases including Alzheimer's disease. In the current phase 1 study, the IP is tested in healthy volunteers, and the purpose is to investigate the safety, tolerability, and PK of single and multiple ascending oral doses of SNP318.

Read the detailed description

A total of approximately 86 healthy male and female adult participants aged 18 years and older will be enrolled in this study, that will be conducted in 2 parts:

Part 1-Single Ascending Dose (SAD) and Part 2 -Multiple Ascending Dose (MAD). Part 1 is subdivided into Part 1a and Part 1b. Part 1b is a cohort for cerebrospinal fluid sampling.

There are 6 cohorts planned for Part 1a SAD, 1 cohort for Part 1b SAD and 3 cohorts for Part 2 MAD.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SNP318 (A) in people with Neurodegenerative Diseases and Alzheimer's Disease, run by SciNeuro at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and tolerability of SNP318 in healthy adult participants. Assessed by adverse events (time frame: Up to 20 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2023.
