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.

Detailed Description

In order to evaluate the long-term safety and efficacy of ORADUR®-Methylphenidate in children and adolescents with ADHD, subjects who participated in the previous OP-2PN012-301 study will be invited to join this extension study for 24-month follow-up. Subjects will continue to receive ORADUR®-Methylphenidate at the previously determined optimal dose.

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.

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

2 years to 14 years (Child, Adult)

Accepts Healthy Volunteers

No

Main Inclusion Criteria:

  1. Subjects previously enrolled in OP-2PN012-301 study and completed 4-week study treatment
  2. Both subjects and parents/guardians have provided their signed and dated informed consent form for the study

Main Exclusion Criteria:

  1. Subjects who experienced unmanageable adverse events (AEs) after receiving ORADUR®-Methylphenidate
  2. Subjects are taking a concomitant medication (ex: Monoamine Oxidase Inhibitor (MAOI) or other ADHD treatments) that is likely to interfere with safe administration of methylphenidate within 14 day prior to the study treatment initiation
  3. Subjects are joining other clinical studies and receiving any other investigational medical products within 14 days prior to the study treatment initiation.
  4. By the investigators' discretion, subjects with serious or unstable medical illness that will interfere with the evaluations of study efficacy and safety
  5. By the investigators' discretion, subjects cannot understand or follow the instructions given in the study
  6. Psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule

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

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.
