Detailed Description
Pain management in PD is a recognised unmet need. Estimates of incidence vary in the literature from 29% to 83%. The types and sources of pain experienced by PD patients vary and include: musculoskeletal pain, PD related chronic pain, fluctuation-related pain, nocturnal pain, coat-hanger pain, oro-facial pain and peripheral limb or abdominal pain (also including drug-induced pain). Whilst modifications to dosing of dopaminergic therapy represents the most common method of controlling some of these pain symptoms, this must be balanced against the worsening of side effects of increased doses of this treatment type.
Oxycodone hydrochloride and naloxone hydrochloride dihydrate combined oral prolonged release tablets (OXN PR), is the investigational product to be used in this study. OXN PR is a prolonged release tablet consisting of oxycodone and naloxone in a 2:1 ratio. Due to the local competitive antagonism of the opioid receptor-mediated oxycodone effect by naloxone in the gut, naloxone reduces opioid-associated bowel dysfunction.
The purpose of this study is to investigate whether effective pain control for the treatment of PD associated pain may be achieved with OXN PR. The secondary considerations for this study are to examine whether OXN PR may offer any additional benefits to the patients Quality of Life or symptoms of PD. If effective pain relief can be achieved with an analgesic without the side effects described in above, this could reduce the need to increase the dose of dopaminergic medications to manage pain, and therefore reduce the negative side effects of dopaminergic therapy described above. Given the prevalence of constipation in this patient population the bowel sparing effects of the OXN PR combination treatment may provide an ethical rationale for its use over that of other opioids.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria
- Males and females, age of 25 years or over
- Able to provide written informed consent
- Primary diagnosis of Parkinson's disease Stage II-IV)
- Graded as having severe pain
- An average pain score of 6 or above on an 11 point NRS, over the previous 7 days
- Female subjects willing to use an adequate and highly effective method of contraception throughout the study.
- Subjects likely to benefit from WHO step III opioid therapy for the duration of the study
- Subjects must not have received opioid containing medication in the last 6 months on a regular basis
- Receiving stable treatment for Parkinson's disease for at least 4 weeks prior to randomisation
- Subject does not have visual or auditory impairments that would reduce their ability to complete study questionnaires or be unable to receive instructions for these
- Concomitant medication (including co-analgesic) use anticipated to remain stable throughout the Double-Blind Phase of the study
- Subjects willing and able to participate in all aspects of the study and comply with the use of study medication.
Open-Label Extension Inclusion Criteria
The aim of the Open-Label Phase is to ensure a safe transfer of all subjects to a subsequent pain treatment after the study. Subjects must:
- Still meet general inclusion criteria for Double-Blind Phase; subjects do not have to meet inclusion 5, 6, 9 & 12
- Have completed the Double-Blind Phase or discontinued early but have had at least 8 weeks treatment with study medication.
Exclusion Criteria
Subjects who are to be excluded from the study are those who meet any of the following criteria:
Medical Conditions
- Cognitive impairment as assessed with the MMSE scoring 24 or less
- History of psychosis (hallucinations, delusions, etc.)
- History of drug or alcohol abuse or current compulsive addictive use of drugs or alcohol
- Parkinsonian-like disease secondary to drug therapy side-effects e.g. due to exposure to medications that deplete dopamine (reserpine, tetrabenazine) or block dopamine receptors (neuroleptics, antiemetics)
- Parkinson-plus syndromes e.g. progressive supranuclear palsy (PSP) and the multiple system atrophies (MSA)
