Continued Efficacy of Apomorphine After Previous Exposure of at Least Three Months

December 15, 2005 updated by: Mylan Bertek Pharmaceuticals

A Prospective, Randomized, Placebo-Controlled, Crossover Study of the Safety and Effectiveness of Subcutaneous Injections of Apomorphine in the Treatment of "Off" Episodes in Patients With "On/Off" or "Wearing Off" Effects Associated With Late Stage Parkinson's Disease

The objective of this study was to measure the continued efficacy of apomorphine after previous exposure of at least three months duration.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

This was a prospective, double-blind, randomized, placebo-controlled, crossover desigh, multicenter study of the safety and effectiveness of subcutaneous apomorphine treatment. Patients received both apomorphine and placebo, in a randomized double-blind fashion

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients diagnosed with idiopathic Parkinson's Disease and classified as stage II-IV of the Hoehn and Yahr scale for staging the severity of Parkinson's Disease
  • Patients must have been on an optimally maximized oral therapy regimen including levodopa/decarboxylase inhibitors in either immediate or delayed release forms, plus at least one direct acting oral dopamine agonist for at least 30 days prior to randomization
  • Patients must have been receiving apomorphine subcutaneous injections for rescue therapy for "Off" events for at least three months with an average dosing requirement of at least 2 doses per day over the week prior to enrollment with a dose of less than 11 mg

Exclusion Criteria:

  • Patients under medical therapy for clinically significant psychoses or dementia not related to ingestion of antiparkinson medications. (Patients with hallucinations or other central adverse reactions associated solely with antiparkinson medications were not excluded.)
  • Patients with a history of drug or alcohol dependency within one year prior to study enrollment
  • Patients with unstable and clinically significant disease of cardiovascular (including orthostatic hypotension), hematologic (including Coombs' positive hemolytic anemia), hepatic, renal, metabolic, respiratory, gastrointestinal or endocrinological systems or neoplasm within the threemonths before the start of the study.
  • Patients with a history of allergy or intolerance to morphine or its derivatives, sulfur, sulfur containing medication, sulfites, domperidone, trimethobenzamide or other anticholinergics.
  • Patients treated with experimental agents (other than apomorphine intermittent subcutaneous injections) within 3 months before study entry, experimental agents were defined on the basis of the regulatory status in the country of patient observation, or with other disallowed medications
  • Patients whose apomorphine regimen was characterized by continuous infusion or by administration methods other than intermittent subcutaneous injection.
  • Patients who could not or would not sign an informed consent form.

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
UPDRS Motor Score 20 minutes after dosing

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
Dyskinesia Rating Scale 10, 20 and 60 minutes after dosing
Time to onset of perceived relief
AUC for UPDRS Motor Scores at predose, 10, 20 and 60 minutes
Change in UPDRS Motor Scores at 10 and 60 minutes after dosing
