Abstract
A Complex Market of Diverse Needs
Neuropathic pain (NP) can have chronic, debilitating impact on the lives of
patients with a variety of conditions, including low back pain, diabetes,
herpes, trigeminal neuralgia, HIV/AIDS, neuropathic cancer pain and
fibromyalgia. Many patients and their physicians fail to realize the
neuropathic nature of some patients' pain, including severe burning, stinging,
and shooting pain. This general lack of awareness is largely due to the
complicated nature of the onset of NP, difficulty in confirming diagnoses, and
the lack of effective treatments.
An Opportunity to Meet Unmet Need for Therapy
By 2018, there will be approximately 6 million individuals in US suffering
from major NP conditions.
Given this substantial patient population, NP has received particular
attention in recent years due to its relative resistance to conventional
analgesic therapies. Importantly, many analgesic drugs, from nonsteroidal
anti-inflammatory drugs to strong opiates, have proven to be either
ineffective or to provide only limited relief. More pharmacological therapies
have been approved specifically for the treatment of NP in recent years.
There is still a great need to develop novel therapies that are safe and
effective. Recent research elucidating the mechanisms of NP has provided new
targets for pharmacological interventions that have captured the attention of
the pharmaceutical industry.
Report Objectives & Methodology
In this report WWMR, Inc., provides an overview for ten major conditions
causing NP in the US market.
This report also summarizes WWMR, Inc.' s current understanding of NP
mechanisms, and highlights promising targets for drug development. Also
reviewed are new treatments already in development that offer the promise of
improved pain management of NP in the near future.
Models representing patient populations and the commercial value (USD) of this
market in 2008, 2013, and 2018 are presented. These models describe the
important features of key conditions associated with NP:
- Neuropathic back pain
- Diabetic neuropathy
- Complex regional pain syndrome
- HIV/AIDS neuropathy
- Post-herpetic neuralgia
- Phantom limb pain
- Spinal cord injury
- Trigeminal neuralgia
- Fibromyalgia
- Neuropathic cancer pain
Expert analysis and commentary describing the future NP market are based on:
- WWMR' s Pain Clinic Monitor, profiling neuropathic pain conditions
- Comprehensive analysis of uses for specific conditions, including
estimations of prescription size, number of refills, and cost
- Evaluation of drugs in the NP drug pipeline, with conclusions on the
future directions in treatment
- In-depth analysis of the medical literature, including treatment review
articles, medical textbooks, epidemiology studies, and clinical studies
- Thorough review of country-specific and overall trends
Market and patient population forecasts are based on a consensus developed
from industry experience, clinician input, and analysis of secondary sources.
WWMR' s US Neuropathic Pain report will allow pharmaceutical and biotechnology executives to:
- Compare the epidemiology of neuropathic pain, including projected growth
rates, by indication
- Recognize the specific conditions associated with neuropathic pain that
have high market potential in the next 10 years
- Target specific patient populations who will benefit most from drugs in
the neuropathic pain pipeline
- Anticipate upcoming competitors and product licensing opportunities
- Understand the type and level of unmet need in the US neuropathic pain
market
- Recognize the impact of special market dynamics, including potential
off-label usage, on product uptake forecasts
