About this study

Official title: A Phase 1 Randomised, Double-blind, Placebo-controlled, Parallel Group, Single Ascending Dose (Part A) and Multiple Ascending Dose (Part B) Study to Assess the Safety, Tolerability and Pharmacokinetics of IV Infusion of TESP-0401 in Healthy Participants

The goal of this intervention study is to evaluate the safety and tolerability of TESP-0401, and to understand how the body processes TESP-0401, in healthy participants after single and multiple doses. The study aims to answer the following questions: 1. What are the safety, tolerability, and pharmacokinetic characteristics of a single dose of TESP-0401 in healthy participants? 2. What are the safety, tolerability, and pharmacokinetic characteristics of multiple doses of TESP-0401 in healthy participants? This study will be a randomized, placebo controlled study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TESP-0401 in people with Healthy Volunteers, run by Tes Pharma S.r.l. 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 9 inclusion and 28 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: looking for participants now, as of the sponsor's last update on 14 Sep 2026. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Jennifer Martin (+6140961159, jennifer@novatrials.com.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with SAEs, TEAEs, with abnormal clinical laboratory tests results, abnormal vital signs, abnormal ECG readings and abnormal physical examination findings (time frame: up to 8 days after the last dose). 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 14 Sep 2026.
