About this study

The objective of this study is to establish the bioequivalence of two levothyroxine formulations through the estimation of T4 levels in serum samples after baseline correction, according to Food and Drugs Administration (FDA), World Health Organization (WHO) and Colombian National Vigilance Institute for Drugs and Food (INVIMA) guidelines.

Read the detailed description

Levothyroxine (T4) is used to treat patients with hypothyroidism and may often result in lifelong therapy. Its physiologically active metabolite is tri-iodothyronine (T3). Levothyroxine is also endogenously produced in the body. Since small changes in levothyroxine administration (e.g. change in brand or formulation) can cause significant changes in serum thyroid stimulating hormone (TSH) concentrations, precise and accurate TSH control is critical to avoid potential adverse iatrogenic effects. Tecnoquimicas modified its Levothyroxine tablets formulation in order to comply with new pharmacopeical specifications. It will then evaluate the impact on drug product performance based on pharmacokinetic (PK) measures of total serum T4 and total serum T3 of the new formulation of levothyroxine (Test formulation) relative to the reference formulation from Merck (Reference formulation)

This will be a single-center, open-label, two-period, two-treatment, two-sequence, randomized, single-dose, crossover study. 80 healthy adults will be randomized to receive a single dose (4 x 150 mcg tablets = 600 mcg) of the test formulation of levothyroxine and reference formulation of levothyroxine separately in each treatment period. There will be two treatment sequences (AB, BA) and a 42 day washout between the two treatment periods.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Drug Levothyroxine 150 mcg and Drug Eutirox 150 mcg in people with Healthy, run by Tecnoquimicas at 1 site in Colombia.

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 6 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: status not confirmed, as of the sponsor's last update on 16 Aug 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 Colombia. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

(AUC) Area Under the Curve 0-48 for T4 (time frame: From 0 to 48 hours). 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 16 Aug 2018.
