I. CLINICAL SECTION 1.1 INTRODUCTION AND BACKGROUND
Pain is of one of the major reasons patient’s visit a physician. About 20% of
patients visiting a physician have experienced pain for more than 6 months. The
management of pain requires active intervention and the adroit use of
medications limiting potential addiction and abuse.
Pharmacologic treatment of pain often depends on opiates with their addictive
and abuse potential. Additionally, there is no one analgesic agent that is effective
without side effects and without dose limitations. Compounded formulations
consisting of multiple therapies are evolving as viable treatment options for pain
therapy. The use of topical therapy to replace oral or intravenous therapy for
external, surface or joint pain is a viable approach. This study proposes to
evaluate the analgesic activity of a compounded topical formulation(s) in
participants with painful joints, topical extremity pain, arthritis, or other chronic
conditions needing pain management. The study wil compare two proprietary
cream therapies to the only current topical cream Voltaren gel. Two different
creams wil be employed, the choice is at the discretion of the treating physician.
1.2. STUDY DRUG
The topical cream contains one of two preparations:
2. OBJECTIVES
2.1. Primary Objective. The primary objective of this study is to determine the
analgesic effect of the topical cream in patients with chronic pain.
3. RESEARCH DESIGN AND METHODS
This study is an open label, randomized positive control ed 6-month study that
randomly assigns participants who are initial y screened and found to have
chronic pain. Participants wil be instructed to apply the creams up to 4 times in a
day. At the initial visit, 6 weeks and 6 months visits an evaluation wil be made
based on the level of pain, compliance to medication, and any adverse effects of
The primary outcome variable wil be the physician global assessment scale
(Table 1) evaluated by the study physician. Patients wil be initial y be evaluated
by a physician and certified to be suffering from chronic pain condition.

4. DURATION 4.1 Duration of Subjects Participation: Each participant will be in the study for 5. NUMBER OF SUBJECTS
The sample size and power calculation is based on the fol owing considerations:
The primary objective of the study is to evaluate if a topical ointment can cause
al eviation of pain. Thus, the study is powered to be able to show a 5 %
improvement in pain, measured on the Numeric Pain Intensity Scale, compared
to the positive control group (SD 50%). The computation indicates that 3,564
patients needed in each arm of the study to have 95%power to detect 5 %
improvement to be statistical y significant with a two-sided alpha error of p<0.01.
Thus a total of 10,692 patients are required, 3,564 in each of the three study
arms. Considering that up to 30% of the participants wil not complete the study
compliant with the protocol, participants wil be added for a total enrol ment of
6. SUBJECT RECRUITMENT
Study patients will be recruited by physicians who treat chronic pain conditions.
We expect to recruit up to 100 physician centers with each center contributing up
to 100 patients. Patients of any gender or race who meet the inclusion and
exclusion criteria are eligible for the study.
6.1. Inclusion Criteria:
1) 18 and 85 yr old female or male patients
2) Chronic extremity, joint muscular skeletal, neuropathy, or topical pain lasting
for more than 2 months, interfering with daily activities, work, or sleep.
3) Any systemic disease (cardiac, renal, or hepatic) must be wel control ed.
4) Absence of skin lesions at the site of application of the study medication
6.2. Exclusion Criteria:
1) Pregnant or lactating females or women at the child bearing potential not
2) Use of other topical or transdermal medication. Patients may be withdrawn for
a period of 2 weeks from all topical or transdermal medications prior to study
3) Hypersensitivity to local anesthetic or other ingredients of the compounded
4) Prior reconstruction skin surgery or skin grafts in the area of cream
application preventing absorption of cream.
5) Chronic pain conditions not expected to respond to topical pain medication
such as deep abdominal pain, or from conditions such as cancer, or gouty
6.3. Concomitant Treatment and Restrictions. Medication known to adversely
react with those in the topical ointments.
6.3.1. Concomitant Medications
Participants are required to avoid applying any analgesic topical cream or
transdermal medication for chronic pain conditions other than study medications.
Oral medications may have their dose reduced during the course of the study. A
reduction in oral medications wil be recorded in the patients chart and reported
on the electronic case report form. A reduction in oral medication dose wil be a
measure of efficacy of therapy if it correlates with no change, or a reduction of
pain as measured by the pain scale questions.
7. SCREENING FAILURES
Volunteers who are evaluated for entry into the study and fail to meet the
inclusion and exclusion criteria are defined as screening failures. A screening
log, which documents the screening number, volunteer’s initials, and reason for
screening failure, is to be maintained by the investigator. A copy of the log should
be retained in the investigator’s study files.
8. WITHDRAWAL FROM THE STUDY
Participants may withdraw from the study at any point. The Investigator shal
provide the reason for premature subject termination or withdrawal in the CRF.
9. STUDY METHODS 9.1. Pre-study screening
A brief evaluation if the patient meets inclusion and exclusion criteria wil be
performed and the result wil be documented in a Case Report Form. If the
volunteer is eligible for the study, he or she wil be al ocated to one of the two
study creams (at the prescribing physician’s discretion) or the control cream (if
patients insurance does not cover the formulated creams). The pre-study
screening must be performed within 2 weeks prior to study entry.
9.2. Study Procedures
If the volunteer meets the study entry criteria and has signed the informed
consent, the volunteer wil be scheduled for treatment.
Physical exam wil be performed by the physician at baseline 6 weeks of
Simple Descriptive Pain Intensity Scale and numeric pain intensity scale
will be employed at the baseline, after 6 weeks and 6 months of study.
9.2.1. Schedules of study topical cream administrations:
Types of ointment employed in this study:
Topical cream (active agent) – Type A or Type B
10. STUDY MATERIALS 10.1. Study Ointment 10.1.1. Topical creams wil be provided by the sponsor. 10.1.2. Voltaren will be purchased by the patients. 10.2. Medication Assessment: The physician at each site wil chose which
cream the patient shal receive (Cream A or B). If patients insurance does not
permit the compounded cream, then they wil be given the Voltaren Gel.
10.3. Case Report Forms (CRF)
Case report forms wil be prepared by American Institute Therapeutics an
11. PRECAUTIONS
Patients wil be closely monitored for potential side effects .
12. ADVERSE EVENTS
By definition, an adverse event (adverse experience) is any untoward, undesired,
unplanned clinical event in the form of signs, symptoms, disease, or laboratory or
physiological observations occurring in a human being participating in a clinical
study, regardless of causal relationship. This includes the fol owing:
• Any clinical y significant worsening of a pre-existing condition.
• an adverse event occurring from overdose, whether accidental or intentional
• an adverse event that has been associated with the discontinuation of the
All adverse reactions observed and/or reported during the course of the study
must be recorded in the patient’s Case Report Form (CRF). The Investigator
should record the type, severity (intensity), time of occurrence, duration, and
frequency (reoccurrence) of each event, and its relationship to the use of the
study medication (none, possibly related, probably related, definitely related).
The Investigator must record, when applicable, any treatment administered
because of any adverse reaction, inclusive of clinical observations, medications
used, laboratory procedures and/or other therapeutic measures applied. Any
adverse event must be recorded in the volunteer’s case report form.
13. STATISTICAL TESTING
The statistical analysis wil consist of computation of means and standard
deviations for continuous variables and frequencies for categorical variables.
Changes from baseline in continuous variables (i.e. pain intensity) fol owing
administration of topical cream wil be analyzed by paired sample t tests. If the
variables don’t have normal distribution, non-parametric tests wil be employed.
Categorical variables wil be evaluated by Fisher’s exact test. A two-sided alpha
error of p<0.05 wil be considered to be statistical y significant
14. MANAGEMENT OF EMERGENCIES 14.1. Acute Emergencies and Adverse Events
The subject wil be treated as medical y appropriate at the discretion of the
investigator. In case of a very unlikely adverse event that wil not spontaneously
resolve, or by the judgment of the investigator needs emergency treatment, the
volunteer wil be transferred to a hospital or emergency room for further care as
warranted. All emergencies and adverse events including treatments wil be
