Phase IIa Multicentre Study Investigating of VR040 in Parkinson's Disease

• Status: Completed
• Trial end date: 2009-07-01
• Target enrollment: 0
• Participant gender: All

Summary

'Off periods' where people with Parkinson's disease are slow, stiff and unable to function are disabling, and a treatment which can converts people to a "on", good, able to function state would be extremely useful. We assessed safety, tolerability and efficacy of inhaled dry powder apomorphine (VR040) in a clinic-based study in this setting.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: South Glasgow University Hospitals NHS Trust
• Collaborator: Vectura Limited
• Treatments: Apomorphine

Criteria

Inclusion Criteria:

1. Male or female between 30 and 90 years old with idiopathic PD for at least 5 years.

2. Voluntary written informed consent provided.

3. Willing and able to comply with study procedures.

4. Fulfilled steps 1 and 2 of the UK Brain Bank Criteria.

5. Classified as Hoehn and Yahr Stage II to IV in "on" state.

6. Motor fluctuations with recognisable "off" periods in control of motor symptoms, as assessed by the Motor Fluctuation Questionnaire.

7. Optimised oral therapy.

8. Dopaminergic responsiveness as defined by ≥ 30% improvement(reduction) in UPDRS III score compared with pre-dose value.

Exclusion Criteria:

1. Participated in a trial with an investigational product within prior 3 months.

2. Serious uncontrolled disease including serious psychological disorders.

3. Previous intolerance to apomorphine.

4. Previous significant complication from oral dopamine agonist therapy

5. Women lactating, pregnant or of child-bearing potential not using a reliable contraceptive method (eg, barrier, intrauterine device, abstinence).

6. Known HIV or active chronic hepatitis B or C infection.

7. Any clinically significant abnormality following review of screening observations

8. Patients who, in the Investigator's opinion, were unsuitable for the study for any reason.

9. Major ECG abnormalities.

10. Patients with a FEV1 ≤ 65% predicted.

11. Patients showing a postural decrease in systolic blood pressure (BP) of ≥20 mm Hg or showing significant clinical symptoms associated with orthostatic hypotension.

12. Patients with persistent arterial hypotension, with average systolic readings of ≤110 mm Hg.

13. Patients with persistent elevation of BP, with average systolic readings of ≥160 mm Hg.

or average diastolic readings of ≥100 mm Hg.

14. Patients taking apomorphine at any time during these study visits, anabolic steroids,traditional antipsychotics (unless low dose) and vasodilators other than for the treatment of hypertension. The following atypical antipsychotics were permitted: Quetiapine (up to and including 50 mg per day), risperidone (up to and including 1 mg per day) and olanzapine (up to and including 2.5 mg per day).

15. Patients taking agents of the 5HT3 antagonist class including ondansetron, granisetron,dolasetron, palonosetron and alosetron.

16. Patients with existing cancer and those in remission for less than 5 years.

17. Patients with evidence (as ascertained from examination, tests or history) to indicate cardiovascular, gastrointestinal tract, liver, kidney, central nervous system, pulmonary system or bone marrow disorders that in the Investigator's opinion compromised patient safety.

18. Patients who were known non-responders to apomorphine treatment for "off" episodes(eg, in previous challenge tests or trials).

19. Patients with a history of drug or alcohol abuse in the 12 months prior to entry.

20. Patients with a history of clinically significant allergies to VR040 formulation constituents (including lactose and opioids) and domperidone.

21. Patients with signs or symptoms suggestive of psychosis, dementia, "Parkinson-plus" syndromes or unstable systemic disease.

22. Patients with history of stroke, seizure or other neurological conditions.

23. Patients with dyskinesia rated 4 in Item 32 of UPDRS IV assessment at Screening(dyskinesia present ≥76% of a waking day).
