About this study

Official title: Phase 1 Double-Blind, Placebo Controlled, Dose-Escalation Safety, Pharmacokinetic and Pharmacodynamic Study of Orally-Administered AMXT 1501 Dicaprate in Normal Healthy Volunteers

This is a Phase 1 study, which will assess the safety, PK, and pharmacodynamics (PD) of orally-administered AMXT 1501 dicaprate in normal healthy male volunteers.

The study is comprised of a total of 8 cohorts; 4 single ascending dose (SAD) cohorts, 1 Food Effect (FE) Crossover cohort, and 3 multiple ascending dose (MAD) cohorts. Tablets will be administered after an overnight fast (10 hours) with at least 250 mL water. No food will be administered (exception for "fed" subjects, see below) for one hour thereafter.

Each cohort will have a total 6 subjects: SAD and MAD (2 subjects receiving placebo and 4 subjects receiving active AMXT 1501 dicaprate); and FE crossover (6 subjects receiving active AMXT 1501 dicaprate).

The Phase 1 study, which will assess the safety, PK, and pharmacodynamics (PD) of orally-administered AMXT 1501 dicaprate in normal healthy male volunteers.

The study is comprised of a total of 8 cohorts; 4 single ascending dose (SAD) cohorts, 1 Food Effect (FE) Crossover cohort, and 3 multiple ascending dose (MAD) cohorts. Tablets will be administered after an overnight fast (10 hours) with at least 250 mL water. No food will be administered (exception for "fed" subjects, see below) for one hour thereafter.

Each cohort will have a total 6 subjects: SAD and MAD (2 subjects receiving placebo and 4 subjects receiving active AMXT 1501 dicaprate); and FE crossover (6 subjects receiving active AMXT 1501 dicaprate).

SAD cohorts are defined as follows:

  • Cohort 1: One placebo and one AMXT 1501 dicaprate subject will be treated as sentinel subjects receiving one tablet each of their assigned treatment. Assuming no intolerance is noted after at least 3 days, the remaining cohort subjects (placebo, 1 subject and AMXT 1501 dicaprate, 3 subjects) will be treated.
  • Cohort 2: 2 subjects 2 placebo each and 4 subjects 2 AMXT 1501 dicaprate tablets each
  • Cohort 3: 2 subjects 4 placebos each and 4 subjects 4 AMXT 1501 dicaprate tablets each
  • Cohort 4: 2 subjects 8 placebos each and 4 subjects 8 AMXT 1501 dicaprate tablets each

FE Crossover:

  • Cohort 5: 6 new subjects will be randomized to a fed (n=3 standard meal) or fasted (n=3) group and administered one dose lower of the maximum tolerated AMXT 1501 dose in the previous SAD cohorts. First dose and accompanying assessments will be referred to as Period 1. Subjects will then crossover to the opposite diet plan (fed or fasted) and receive a second administration of study treatment at the same dose level. The second dose and assessments are referred to as Period 2. There will be a 7-day washout between doses administered in Periods 1 and 2.

MAD cohorts will receive dosing once daily for 14 consecutive days. Dosing will be contingent on adequate tolerance in Cohorts 1-5.

  • Cohort 6: 2 subjects 2 placebos each; 4 subjects 2 AMXT 1501 dicaprate tablets each
  • Cohort 7: 2 subjects 4 placebos each; 4 subjects 4 AMXT 1501 dicaprate tablets each
  • Cohort 8: 2 subjects 8 placebos each; 4 subjects 8 AMXT 1501 dicaprate tablets each

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AMXT 1501 in people with Neoplasms and Medication Toxicity, run by Aminex Therapeutics, 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 7 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: withdrawn, as of the sponsor's last update on 14 Jun 2018. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Determine the maximum feasible dose (MFD) (time frame: 6 months). 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 14 Jun 2018.
