About this study

Official title: A Phase 1, Double-Blind, Randomized, Placebo-Controlled, Multiple Ascending Dose Study to Assess the Pharmacokinetics, Safety, and Tolerability of Orally Administered SYN 020 Delayed Release Capsules in Healthy Subjects

This is a Phase 1, randomized, double-blind, placebo-controlled, multiple-ascending-dose study to assess the PK, safety, and tolerability of SYN-020 oral delayed release capsules (SYN 020) in healthy adults. At least 1 exploratory PD endpoint will also be assessed.

Read the detailed description

Randomization to treatment will be stratified by sex, with equal numbers of males and females receiving each treatment in each cohort. Up to 5 ascending-dose cohorts of 8 subjects each will be enrolled, and all cohorts will be conducted as planned or until the safety data do not support further escalation. SYN-020 (or placebo) will be administered every 12 hours for 14 consecutive days at escalating doses of 5, 15, 45, and 75 mg in Cohorts 1 through 4, and at a dose not to exceed 75 mg in Cohort 5.

Subjects will be screened within 28 days before admission to the clinical research unit (CRU). For each cohort, eligible subjects will be admitted to the CRU on Day -1, and subjects who remain eligible will receive the first dose of study drug in the morning (AM) of Day 1. Subjects will receive study drug every 12 hours for 14 consecutive days. No restriction in food or fluids is required around dosing for any dose other than the AM dose on Days 1 and 14. Subjects will also fast overnight before blood samples are collected for clinical laboratory and/or PD tests on Days 2, 6, 8, 10, 14, and at the follow-up visit on Day 35. A standard Western diet appropriate for a Phase 1 study will be provided at approximately the same times each day during confinement, with each cohort receiving the same meals.

Subjects will be discharged from the CRU after the End of Study (EOS) procedures are completed in the AM on Day 15 and will return to the CRU for a follow-up visit on Day 35.

For PK assessment, blood samples (primarily on Days 1 and 14) and feces (pre-dose and over selected 48 hour time intervals) will be collected for analysis of SYN 020 concentrations.

For PD assessment, blood will be collected and analyzed (or stored for future analysis) for at least 1 of the exploratory endpoints. Fecal samples for PD assessment will be taken from the feces collected for PK assessment. These investigations will explore potential biomarkers for future SYN 020 indications and will be strictly and directly related to the pharmacology of SYN 020. While gastrointestinal microbiome/metabolome analyses include genotyping of the gut bacteria, no human genotyping will be performed.

Safety and tolerability will be monitored throughout the study. Safety assessments will include clinical laboratory tests, vital signs, 12-lead ECGs, physical examinations, monitoring for AEs, and ADA testing. Adverse event data will be collected from the time of informed consent through the follow-up visit at Day 35 or until the AE resolves or becomes stable.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SYN-020 Delayed Release Capsule in people with Enteritis Caused by Radiation, run by Theriva Biologics, 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 20 inclusion and 11 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 21 Apr 2022. 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. 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?

SYN-020 systemic absorption (time frame: Day 1 to Day 15). The study lists 2 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 21 Apr 2022.
