Trial summary

This research is being done to evaluate if NRP 104 is a safe drug. The other purpose is to learn if NRP104, when injected into a vein, produces a high and any other effects like amphetamine and other stimulant drugs that are abused. This information will give some indication if NRP104 can be abused. Read more about this study

About this study

Official title: A Double-Blind Placebo- and Active-Controlled, Single-Dose Crossover PD and PK Study to Evaluate the Safety, Tolerability and Abuse Liability of IV Administered NRP104 25 mg and 50 mg in Adult Volunteers With Histories of Stimulant Abuse

This research is being done to evaluate if NRP 104 is a safe drug. The other purpose is to learn if NRP104, when injected into a vein, produces a high and any other effects like amphetamine and other stimulant drugs that are abused. This information will give some indication if NRP104 can be abused. Healthy people, between the ages of 18 and 55 with histories of substance abuse that include stimulant drugs, may join. Amphetamines are drugs that are used most often to treat attention deficit hyperactivity disorder (ADHD) in children, to treat narcolepsy (excessive sleepiness) and for weight loss.

Read the detailed description

There is a need for a non-scheduled stimulant medication that can provide symptom control for children with ADHD as the conventional stimulant products do.

Currently, the top line amphetamine product Adderall XR (R) for the treatment of children with ADHD involves a once-a-day morning dosing of up to 30 mg per day per Adderall XR (R) Package Insert. New River Pharmaceuticals has developed three NRP104 dose strengths of 30 mg, 50 mg, and 70 mg to provide amphetamine base equivalent to Adderall XR (R) 10 mg, 20 mg, and 30 mg, respectively. Adderall XR (R) and other amphetamine and methylphenidate containing preparations are liable to intravenous abuse.

As part of the development of NRP104 for treatment of children with ADHD, it is important to evaluate the abuse potential of NRP104 given intravenously in comparison to immediate release d-amphetamine. This study will conduct relevant information to address appropriately the objectives of determining abuse potential of intravenously administered NRP104.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pharmacodynamic (PD) Parameters:

  2. The following parameters will be measured at fixed time intervals post drug and used to compare the

  3. effects of various doses of NRP104 with placebo and d-amphetamine sulfate for pharmacodynamic

  4. equivalence:

  5. (1) Maximum liking scale scores for euphoria measured by DRQS and DRQO

  6. (2) Maximum disliking scale scores for dysphoria measured by DRQS and DRQO

  7. (3) Maximum scores on the MBG, BG and Amphetamine scales of the ARCI

  8. (4) Maximum supine systolic and diastolic blood pressure changes from baseline

  9. (5) Maximum orthostatic pulse increases from baseline

  10. (6) Spontaneous reports of discomforting subjective effects

  11. (7) Adverse events, laboratory tests, physical examination, vital signs and ECG will be collected to

  12. assess the safety and tolerability of NRP104.

  13. Pharmacokinetic (PK) Parameters

  14. The following parameters will be calculated using non-compartmental analysis for d-amphetamine and

  15. intact

  16. NRP104: AUC0-24, Cmax , Tmax.

  17. • AUC0-24: Area under the drug concentration-time curve from time zero to 24 hours post dose.

  18. • Cmax: Maximum observed drug concentration from zero hour to 24 hours post dose.

  19. • Tmax: Time at which Cmax occurs.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NRP104 in people with Attention Deficit Disorder With Hyperactivity and Amphetamine-Related Disorders, run by New River Pharmaceuticals 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 9 inclusion and 18 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 5 Nov 2007. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Pharmacodynamic (PD) Parameters:. The study lists 19 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 5 Nov 2007.
