Clinical Study of an injectable, low-dose combination product

for treatment of CRPS pain

Montreal, Canada.

(English long version)

(French version)

 

 

Study Description and Intervention: Complex regional pain syndrome (CRPS) is a rare, severe post-traumatic pain condition affecting distal limbs. Patients who do not spontaneously improve within 12 months of onset, i.e., long-standing CRPS, have a poor prognosis and can often not be effectively treated. Preliminary clinical findings with GBM-5, a new investigational drug, have suggested that low-dose administration of GBM-5 might be an effective treatment for CRPS subjects, but further investigation is warranted.

As the clinical outcome has been shown to vary between CRPS subjects, the proposed trial protocol is tailored to treat the needs of patients individually. The study’s specific aims are:

1) to establish the safety and efficacy of an optimal dose regimen of GBM-5 in reducing long-standing pain in CRPS-I patients;

2) to preserve or restore function, enable patients to manage their condition and improve their quality of life (cognitive function, mood, depression, etc.); and

3) to assess whether patient-centered practice can improve health status and increase the overall quality of life. (Doctor-patient communication increases trust, adherence to treatment, and changes in pain medication use.)

 

Patient recruitment and care will be performed at the:

Clinical Study of an injectable, low-dose combination product

for treatment of CRPS pain

(English long version)

Montreal, Canada

 

 

Background and Significance: While many chronic pain conditions are manageable, complex regional pain syndrome (CRPS) pain can be devastating, and it is one of the most challenging pain conditions in medicine. It is ranked as the most painful form of chronic pain that exists today by the McGill Pain Index and is characterized by severe pain-related changes (allodynia and hyperalgesia), trophic changes, neurovascular abnormalities (abnormal sweating, edema, and skin discoloration), motor changes (tremor, muscle spasm), and joint fibrosis and stiffness. CRPS results in loss of physical function, and can lead to significant and sometimes permanent disability. Additionally, CRPS subjects often experience cognitive changes, anxiety, and depression.

 

Despite the severe pain and disability associated with CRPS, the lack of understanding of the pathophysiological mechanisms supporting this enigmatic condition prevents the rational design of new therapies. Therefore, there is a clear demand for effective treatment options to address this important unmet medical need. Study of the disease has indicated that one single mechanism cannot account for all of the changes seen in subjects with CRPS and, consequently, a single ingredient medication is unlikely to be effective in this patient population.

 

After several years of research, the team at the Montreal Pain Clinic successfully formulated a combination product (namely GBM-5) which might address some underlying mechanisms thought to be involved in the pathophysiology of CRPS, such as neurogenic inflammation, sympathetic dysfunction, etc. This combination solution is a fixed multimodal formulation for intrathecal (IT) or epidural injection, which is clearly differentiated from other strong analgesics by its unique combined synergistic mechanism of action. Promising clinical experiences have been obtained in some of our clinic CRPS patients who had severe intractable pain. Further studies in more subjects are warranted.

 

Study Aims: As the clinical outcome has been shown to vary between CRPS subjects, the proposed trial protocol is tailored to treat the needs of patients individually. The study’s specific aims are:

Aim 1: To establish the safety and efficacy of an optimal dose regimen of GBM-5 in reducing long-standing pain in CRPS-I patients.

Aim 2: To preserve or restore function, enable patients to manage their condition and improve their quality of life (cognitive function, mood, depression, etc.).

Aim 3: To assess whether patient-centered practice will improve health status and increase the efficiency of care and overall quality of life.

 

It is hypothesized that low-dose intrathecal GBM-5 is safe and effective in long-standing CRPS subjects in reducing pain and/or concomitant systemic opioid use, and also improving the subject’s quality of life, independence, and capacity to work.

Study Description and Intervention: Complex regional pain syndrome (CRPS) is a rare, severe post-traumatic pain condition affecting distal limbs. Patients who do not spontaneously improve within 12 months of onset, i.e., long-standing CRPS, have a poor prognosis and can often not be effectively treated.

The purpose of this study will be to evaluate the efficacy of GBM-5 for the management of pain in CRPS-I subjects in an open-label study (subject end of study data will be compared to baseline). The project team will develop a multi-site, pragmatic trial where CRPS subjects will be enrolled to receive GBM-5, either intrathecally or epidurally, and the dose will be titrated until optimal pain reduction or reduction in opiate dose is achieved. The injection can be given every 3 days or weekly, depending on clinical outcome. Subjects can receive repeated treatment when pain returns.

Patient Population. Patients with confirmed CRPS-I of moderate to severe pain intensity are eligible. Main inclusion/exclusion criteria are:

Inclusion: Adults with a confirmed diagnosis of CRPS type I (Budapest Criteria) of at least one year’s duration and a pain severity score in the CRPS-affected limb of 4 or more on an 11-point scale (0-10) may participate after providing written informed consent.

Exclusion: Patients may not participate if they are or may become pregnant or are breastfeeding, have participated in another investigational drug trial within 3 months, have received a sympathetic nerve block within 3 weeks of treatment phase, or have any other clinically significant medical or pain condition.

Anticipated Impact: Projected patient outcomes:
Reduction of pain and/or concomitant systemic opioid use
Improvement of subject’s quality of life, independence, and capacity to work.
Patients in the collaborative care approach will have better-controlled pain, reduced depression, and better quality of life, satisfaction with care, adherence to treatments, and quality of care, as compared to those in the usual care approach.

Research environment: The Montreal Pain Clinic which is a division of Montreal Institute of Pain Management & Anti-Aging Medicine, under the direction of Dr. Gilbert Blaise, anesthesiologist and professor at the University of Montreal, is committed to patient-centered care, communication, clinical practice, and research in the area of pain management, especially in refractory chronic pain, including complex regional pain syndrome (CRPS). Primary goal is to deliver a suitable, long-lasting formulation that would decrease pain, improve cognitive function, and reduce opioid consumption and related side effects.

CRPS RESEARCH IN BRITAIN (UK)

 

  Take part in an online study looking at Complex Regional Pain Syndrome in young people and get an Amazon voucher!

 

Pain can present many challenges for young people and their families. These challenges can last a long time or may change over time. This study looks at the social developmental challenges that young people aged 14 to 25 who experience pain face. Adolescence is an important time of life for developing a sense of identity and future aspirations. This has been seen to be very important for well-being.

A team of researchers at the University of Bath in the UK are conducting research that addresses how young people with CRPS think about their future and how those around them (e.g. parents/caregivers) think about their child’s future.

 

If you are:

 

  • A young person, aged 14-25 years, with CRPS

Or

  • A parent/caregiver of a young person (aged 14-25 years) with CRPS

 

…then you may be eligible to take part in the study!

 

The study simply involves completing a 20-25 minute only survey which asks you to think about the future. Those who take part in the study will receive an electronic Amazon voucher to thank them for their time. Study recruitment is being conducted separately for both young people and parents. To find out more please visit https://wp.me/Pa4hqM-4 or to take part please email crpsstories@bath.ac.uk

 

The study has been approved by the University of Bath Psychology Research Ethics Committee.

Survey is conducted under the direction of Dr. Abbie Jordan.

 

 

___________________________________________________________________________________________

 

I KNOW WHAT YOU'RE THINKING;

WHY SHOULD I PARTICIPATE?

 

First of all, the research being conducted will help the researchers better understand the "puzzle of CRPS/RSD", what causes it, and how it works in the body.

Secondly, the scientific knowledge gained from these studies will lead to the development of better treatments for this painful, neurological syndrome.

New treatments are desperately needed for CRPS..

Thirdly, MOST IMPORTANTLY, CRPS patients living in Canada will benefit from Canadian research and treatments first.

Lastly, doing something NOW that will benefit you later, should be considered as a very good reason to help this excellent researcher gather his data.

LAWSON INSTITUTE

 

Development of a perfusion MRI technique to investigate longitudinal effects of chronic pain on brain function

"The aim of this study is to find a tool for evaluation of treatment success in CRPS patients, Magnetic resonance imaging (MRI) is a diagnostic tool in medicine that generates high quality imaging of the human body without the use of x-rays. It can also provide information regarding how the brain functions, which is referred to as functional magnetic resonance imaging (fMRI). Changes in brain function during the course of treatment will be studied to investigate how such changes can reflect the success of treatment."

Research is done at Lawson Institute at St. Joe's Hospital in London Ontario. Participants will be reimbursed.

"Defining Recovery from CRPS: a patients perspective"

McCabe CS RGN PhD et al

Royal Hospital for Rheumatic Diseases, Bath UK

 

UPDATE MAY 2017 : In July 2012, the CRPS Recovery Team met in Bath, UK to design a research paper on CRPS Recovery.The team consisted of doctors, researchers, scientists and patient research partners (PRPs) who continue to collaborate up to the present day. Our goal was to find out how and why patients recovered.

We used the Delphi method  consisting of two rounds of questionnaires which formed the basis of the research. Questionnaires were "forward  translated" into Dutch, Danish, Polish,German and several other languages for completion by patients in 8 countries. Responses were "back translated" into English.  The basic question was "Are you recovered?" The second round of questionnaires recorded all responses and patients were asked to rank them in order of importance. Responses were rated in percentages.

PARC's Executive Director was honoured to be a member of this International CRPS Recovery team. 

Dr. McCabe authored the first study and Alison Lewellyn PhD authored the second one. Both research papers have been published.

 

UPDATE MAY 2018: We are currently collaborating on another paper for the European Journal of Pain in 2017.

This paper was recently published in 2018.

Hamilton CRPS Research 2012-13

A research team from Hamilton Health Sciences and McMaster University are developing an assessment tool that is specific to complex regional pain syndrome. One part of the assessment was a questionnaire that asked the person to rate their own symptoms and the impact those symptoms had on their daily activities and relationships. We also interviewed people who have experienced CRPS to assist us in this process.

Update October 2012

Brain changes in CRPS are becoming well known. The European Journal of Pain 2012 has recently published a study done by Jenny Lewis PhD of Bath, UK entitled "Body Perception Disturbance."


 

SEPT./OCT. 2011

PARC was able to donate a further $5,000 to Mc Gill University to assist the NIRS studies at Montreal General Hospital. The NIRS machine (laser) will be travelling to San Diego, CA this winter to a busy pain clinic of CRPS patients at UCSD where space and research personnel have been donated. Many thanks to the dedicated Dr. Bennett who will travel and resume the study in California. PARC's contribution will help make this happen. Please read about the NIRS study below.


UPDATE APRIL 2010

 

Dr. Terrence Corderre (left) and Dr Gary Bennett (right), of Mc Gill University shown with the near-infrared spectrophotometer (NIRS) that was purchased with the help of PARC, Great West Life Assurance Company, and the family of Mr. Jeffrey Owens. The NIRS machine has the unique ability to measure blood flow and oxygenation in muscles non-invasively and painlessly via a laser light source and light sensor placed on the skin over the muscle. Drs. Bennett and Corderre are using the machine to test their theory that at least CRPS patients have pain due to an injury to the capillary blood vessels in a muscle.

 

PARC NOTE: With your help, PARC can continue to support the research of these excellent scientists at Mc Gill.

Why is CRPS research important?!

BULLETIN: New research has found markers for CRPS. From Boston, a skin biopsy can now detect distal nerve damage. From Haifa Israel, a saliva test can measure high levels of LDH (lactate dehyrogenase), the same substance found in heart attack victims. It also found high levels of albumin.

DUTCH RESEARCH: In a database of 900,000 patients from 150 GPs in Holland, (specifically patients who attend a doctor), the rate of occurrence has been established as 26.2 in 100,000 patients.This is approximately 1 in every 4,000 people.
