About this study

Official title: Phase 1, Double-Blinded, Placebo-Controlled, Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD) Safety and Pharmacokinetics Trial of AVR-48

This is a Phase 1 (healthy adult volunteers), 2-part, double-blind, randomized, placebo controlled trial to evaluate the safety and pharmacokinetic (PK) profiles of escalating single doses of AVR-48 versus placebo (SAD) and escalating multiple doses of AVR-48 versus placebo (MAD). SAD will be initiated first and include a sentinel dosing design. MAD will not utilize a sentinel design unless the safety monitoring committee requests the addition of sentinels. The MAD will be initiated once the lowest doses from SAD are deemed safe.

Read the detailed description

This is a Phase 1, 2-part, double-blinded, placebo-controlled, randomized SAD/MAD study.

The study will include 2 parts:

  • Part A: SAD phase
  • Part B: MAD phase

Part A - SAD phase Healthy adult subjects will be randomized to receive a single IV dose of either AVR-48 or placebo in each of 3 planned SAD cohorts. Each cohort will consist of 8 subjects in a 3:1 (active:placebo) ratio to have a total of 6 subjects receiving AVR-48 and 2 subjects receiving placebo. Each cohort will be comprised of 50% male and 50% female subjects.

All SAD cohorts will be dosed according to a sentinel dosing design to ensure safety. Initially, 2 subjects will be dosed; 1 subject will be dosed with AVR-48 and 1 subject with placebo. Blood samples for PK and safety clinical laboratory tests will be collected over the following 24 hours. If the site Principal Investigator (PI), in conjunction with the AyuVis sponsored Independent Medical Monitor, determines that acceptable safety is observed in the sentinel administration, the remaining subjects in the cohort will be dosed and identical safety and PK procedures will be performed; 5 subjects will be dosed with AVR-48 and 1 subject with placebo. Sentinel subjects will be dosed at least 48 hours prior to enrolling the remaining subjects of the cohort. All subjects will be followed for 48 hours post-dose.

Blood samples will be collected periodically for PK, cytokine panels, metabolite assessment, and safety labs; urine samples will be collected periodically for metabolite assessment, and routine safety assessments will be completed daily.

Escalation to the next higher dose will only proceed if none of the stopping criteria have been reached and when the safety and tolerability and available plasma PK analysis of the previous dose are acceptable to the site PI, Sponsor, and Safety Monitoring Committee (SMC). A minimum of 3 days will separate each dose escalation.

Part B - MAD phase Healthy adult subjects will be randomized to receive multiple IV doses of either AVR-48 or placebo in each of 3 planned MAD cohorts. Each cohort will consist of 8 subjects in a 3:1 (active: placebo) ratio to have a total of 6 subjects receiving AVR-48 and 2 subjects receiving placebo. A balance of male and female subjects in each cohort will be attempted, but the final ratio of subject sex will be determined by the available subjects who pass screening at the time of enrollment.

For Cohort 1 and Cohort 2, AVR-48 or matching placebo will be administered twice daily, every 12 hours, for a total of 13 doses over 7 days. For Cohort 3, AVR-48 will be administered once daily, for a total of 7 doses over 7 days. Subjects will be monitored for 48 hours after the last dose and will attend a follow-up visit 7 days after dosing completes.

Blood samples will be collected periodically for PK, cytokine panels, metabolite assessment, and safety labs; urine samples will be collected periodically for metabolite assessment, and routine safety assessments will be completed daily.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AVR-48 in people with Safety Issues and Tolerability, run by AyuVis Research, Inc. at 1 site in United States.

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 10 inclusion and 17 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: opening soon, as of the sponsor's last update on 6 Apr 2025. 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 United States. 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 Study Principal Investigator (877-362-2608, sacharya@ayuvis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants who experience Adverse Events (AEs), Serious Adverse Events (time frame: Up to 16 days). The study lists 5 primary outcomes in all. 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 6 Apr 2025.
