Eligibility
Key inclusion criteria
Inclusion criteria:

- A subject will be eligible for inclusion in this study only if all of the following
criteria apply:

Male or female subjects 18-80 years of age

- To be eligible, females patients must have a negative pregnancy test (i.e. serum beta
hCG test) and be of:

1. non-childbearing potential (i.e. physiologically incapable of becoming pregnant).
This includes any female who is post-menopausal. For the purposes of this study,
post menopausal is defined as being amenorrhoeic for greater than 2 years with an
appropriate clinical profile, e.g. age appropriate, history of vasomotor
symptoms. Postmenopausal status will be confirmed by serum FSH and oestradiol
concentrations at screening. Surgical sterility will be defined as females who
have had a hysterectomy and/or bilateral oophorectomy or tubal ligation.

OR b.childbearing potential and agree to commit to one of the protocol-approved methods of
contraception, when used consistently and in accordance with both the product label and the
instructions of a physician, as indicated below: i.oral contraceptive (combined or
progestin only), and the same oral contraceptive regimen has been used for at least two
months prior to study drug administration, and the same method continues throughout the
study and through the follow-up phase of the study.

ii.progesterone implanted rods (Norplant ) inserted for at least two months prior to the
study drug administration (but not beyond the third successive year following insertion) ,
and is continued throughout the study and through the follow-up phase of the study.

iii.an IUD, inserted by a qualified clinician, with published data showing that the highest
expected failure rate is less than 1% per year (not all IUDs meet this criterion)
Acceptable IUDs: TCu-380A (Paragard), TCU-380 Slimline (Gyne T Slimline), TCu-220C,
MULTILOAD-250 (MLCu-250) and 375, NOVA T and CUNOVAT (Novagard), Levonorgesterol (LNG-20)
Intra-uterine System (Mirena/Levonova), and FlexiGard 330/CuFix PP330 (Gynefix). The device
must be inserted at least 2 weeks prior to the Screen visit, and remain throughout the
study and through the follow-up phase of the study.

iv.injectable medroxyprogesterone acetate (e.g., Depo-Provera) and is on a stable dose for
2 months prior to Screen, throughout the study and through the follow-up phase of the
study.

v.complete abstinence from intercourse from at least two weeks prior to Screen, throughout
the treatment phase, and the follow-up phase.

vi.double barrier method if comprised of a spermicide with either a condom or diaphragm
from at least two weeks prior to Screen, throughout the treatment phase, and the follow-up
phase.

- A diagnosis of peripheral neuropathic pain:

- focal neuropathic pain related to nerve injury caused by trauma or surgery not
associated with ongoing infection (examples include post-thoracotomy syndrome,
post-mastectomy syndrome, post-inguinal herniorrhaphy syndrome, post-radical neck
dissection syndrome, traumatic mononeuropathies- bullet wounds, lacerations, road
traffic accidents)

- pain associated with lumbo-sacral radiculopathy; patients with radiculopathy will
only be included if they have pain radiating below the knee and have loss of
small fibre function as indicated by quantitative sensory testing (elevation of
at least one sensory modality threshold in the symptomatic limb - warm sensation
> 9.6 0C and cool sensation > 5.6 0C - in L4, L5 or S1 dermatomes) [Quraishi,
2004].

- carpal tunnel syndrome (CTS); patients with CTS will only be included if there is
evidence of loss of large and small fibre function (confirmed by an
electrophysiological nerve conduction examination and by quantitative sensory
testing - warm sensation > 5.2 0C and cool sensation > 4.5 0C - in median nerve
territory (Anand et al., unpublished data).

- location of pain consistent with the area innervated by the affected nerve(s),
with or without other sensory symptoms in the affected area

- at least three months duration

- Baseline pain intensity score averaging = 4 during the three day prior to study start
as reported on the 11 point pain intensity numerical rating scale. For CTS patients,
peak daily pain will be =4 for at least 3 days prior to enrolment

- Subjects who have received nerve blocks or steroid injections for neuropathic pain may
be included if their most recent nerve block was at least 4 weeks prior to
randomisation.

- Body weight = 50 kg (110 lbs) for men and = 45 kg for women, Body Mass Index
18.5-35kg/m2.

- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) within normal
limits at screening.

- The subject is able to understand and comply with protocol requirements, instructions
and protocol-stated restrictions.

- Signed and dated written informed consent prior to admission to the study.

Key exclusion criteria
Exclusion criteria:

- A subject will not be eligible for inclusion in this study if any of the following
criteria apply:

- Any clinically significant medical history or abnormality found on physical
examination, laboratory assessment or ECG at screening which, in the opinion of the
investigator, could interfere with the interpretation of efficacy or safety data or
which otherwise would contraindicate participation in a clinical study, in particular:

- subjects with non-neuropathic pain component involvement, mononeuropathy
multiplex, or more than one cause or potential cause for pain symptoms (e.g.
trigeminal neuralgia, painful diabetic neuropathy, central post-stroke pain,
phantom limb pain, peripheral neuropathy due to alcoholism, malignancy, HIV,
syphilis, drug abuse, vitamin deficiency, hypothyroidism, liver disease, toxic
exposure, or chronic neck pain);

- subjects with intractable pain of unknown origin or active infection in the area
of nerve injury/compression;

- subjects who have had extensive surgery in the treatment of their nerve injury;

- history of Gilbert's syndrome or elevated bilirubin levels (total, direct or
indirect) in a previous clinical study or at screening;

- history of increased liver function tests (ALT, AST) above upper limit of normal
in the past 6 months;

- positive Hepatitis B surface antigen, positive Hepatitis C antibody or Hepatitis
C nucleic acid result;

- GI disorders that may interfere with safety assessments, e.g. diarrhoea.

- Recent start or change in dosing regimen (£1 month prior to screen) of any medication
which, in the opinion of the Investigator, may interfere with pain assessments or
introduce a risk of drug-drug interactions (e.g. glucocorticoids and some
anticonvulsants, see Section 9.2, Prohibited Medications for details).

- Unable to refrain from excessive use medications (e.g. sedatives) that in the opinion
of Investigator may interfere with efficacy or safety assessments (benzodiazepines
prescribed as hypnotic sleep agents allowed). Subject is unable to discontinue topical
analgesics prior to randomization and for the duration of the study. In the case of
topical capsaicin this will be extended to 4 weeks.

- Subject is unable to refrain from nerve blocks during the study.

- Positive alcohol test or urine drug screen at screening.

- History of regular alcohol consumption exceeding an average weekly intake of > 21
units (or an average daily intake of greater than 3 units) for males, or an average
weekly intake of > 14 units (or an average daily intake of greater than 2 units) for
females.

- Consumption of grapefruit or grapefruit juice within seven days prior to the first
dose of study medication.

- Donation of blood in excess of 500 mL within a 30-day period prior to dosing.

- Participation in a trial with any drug within 3 months before the start of the study
or participation in a trial with a new chemical entity within 4 months before the
start of the study.

- Pregnant or nursing female subjects.

- Known history of hypersensitivity or intolerance to paracetamol products.

- Inability or unwillingness to follow the instruction of the study protocol.

- Known hypersensitivity to capsaicin (if applicable)

- An unwillingness of male subjects to abstain from sexual intercourse with women; or
unwillingness of the male subject to use a condom/spermicide in addition to having
their female partner use another form of contraception (as described in inclusion
criterion for women) if the woman could become pregnant from the time of the first
dose of investigational product until completion of the follow-up procedures.
