This clinical trial will determine the bioavailability and effect of food on TP-3654 in healthy adult participants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Participant has a BMI ≥ 18.5 and ≤ 32 kg/m2 at screening.

  • Participant agrees to avoid the use of concomitant medications (except hormonal contraception or medication provided by the site staff under the direction of the Investigator) from time of screening through the final follow-up visit.
  • Participant agrees to abstain from alcohol, recreational drugs (including marijuana), and nicotine from time of screening through the final follow-up visit.
  • Participant agrees to use acceptable method of contraception during the duration of the study and up to 6 months after last dose.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Part A
Randomized, single-dose, 3-period, 3-way cross-over study to assess the relative bioavailability of TP-3654 capsule formulation (1:5 ratio of API:excipient) vs capsule formulations using a 1:3 and 1:2 of API:excipient ratio.
Drug: TP-3654
capsule, oral administered
Experimental: Part B
Randomized, single-dose, 3-period, 3-way cross-over study to evaluate the effect of food on the PK of the Sponsor's selected TP-3654 capsule formulation (1:3 or 1:2).
Drug: TP-3654
capsule, oral administered

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Cmax for relative bioavailability of TP-3654 in Part A
Time Frame: 13 days
Analysis of the maximum concentration (Cmax) of the relative bioavailability of TP-3654 in two different capsule formulations utilizing the ratio of adjusted geometric means
13 days
The Cmax for relative bioavailability of TP-3654 in Part B
Time Frame: 13 days
Analysis of the maximum concentration (Cmax) of the relative bioavailability of the selected capsule formulation of TP-3654 from Part A when administered in fed versus fasting conditions utilizing the ratio of adjusted geometric means.
13 days
The AUC for relative bioavailability of TP-3654 in Part A
Time Frame: 13 days
Analysis of the area under the concentration (AUC) time curve of the relative bioavailability of TP-3654 in two different capsule formulations utilizing the ratio of adjusted geometric means
13 days
The AUC for relative bioavailability of TP-3654 in Part B
Time Frame: 13 days
Analysis of the area under the concentration (AUC) time curve of the relative bioavailability of the selected capsule formulation of TP-3654 from Part A when administered in fed versus fasting conditions utilizing the ratio of adjusted geometric means.
13 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
The number of adverse events and their severity as reported in healthy adult participants
Time Frame: 47 days
47 days

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 4, 2024

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
