Trial summary

The purpose of this study was to compare the pharmacokinetic (the way a drug enters and leaves the blood and tissues over time) profile of Dilaudid OROS 16mg (Dilaudid Slow Release; hydromorphone HCL) administered under fasting conditions, following a high-fat breakfast meal.

About this study

Official title: An Open-Label Evaluation of the Independent Effect of Coadministration of a High Fat Meal and Naltrexone Blockade on the Pharmacokinetic Profile of Dilaudid OROS (Hydromorphone HCL) 16 mg

The purpose of this study was to compare the pharmacokinetic (the way a drug enters and leaves the blood and tissues over time) profile of Dilaudid OROS 16mg (Dilaudid Slow Release; hydromorphone HCL) administered under fasting conditions, following a high-fat breakfast meal. The study also examined the effect of naltrexone blockade on the pharmacokinetic profile of Dilaudid SR.

Read the detailed description

This was a randomized (patients are assigned different treatments based on chance), open-label, three-way crossover study, performed in normal, healthy adults. Each patient received orally administered treatments (a different treatment during each dosing phase): Treatment A: single dose of Dilaudid SR 16 mg administered under fasting conditions without the naltrexone block;Treatment B: single dose of Dilaudid SR 16 mg administered under fed conditions without the naltrexone block, Treatment C: single dose of Dilaudid SR 16 mg administered under fasting conditions with naltrexone HCL 50mg block (3 oral doses of 50mg each administered 12 hours prior to , at the time of, and 12 hours after Dilaudid SR 16mg administration). There was a 7-day washout period between dosing phases.

Venous blood sampling times were 0 (prior to dosing),2,4,6,8,10,12,16,20,24,30,36,42,and 48 hours after each Dilaudid SR administration. LC/MS/MS (Liquid Chromatography/Mass Spectroscopy/Mass Spectroscopy)techniques were employed for the analysis of plasma for hydromorphone concentration. Each patient randomly received orally-administered treatments of single dose of Dilaudid SR 16mg; under fasting conditions without the naltrexone block; under fed conditions without naltrexone block; under fasting conditions with naltrexone 50mg block (3 oral doses of 50mg naltrexone HCL each administered 12 hours prior to, at the time of, and 12 hours after hydromorphone administration); 7-day washout period between dosing phases.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Hydromorphone HCL 16mg; Dilaudid SR 16mg; Naltrexone (opioid antagonist) 50mg. in people with Analgesia, run by Alza Corporation, DE, USA.

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 2 inclusion and 7 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 27 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

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?

The primary endpoints for the statistical evaluations of the study drug were: Area Under the Concentration-Time Curve from 0 to Infinity and Peak Plasma Concentration.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00399295, which also lists 1 linked publication.

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 27 Apr 2010.
