Filter by:The primary objectives of this placebo-controlled clinical trial are to evaluate the analgesic efficacy and safety of bicifadine at three oral dose levels compared with placebo in patients with moderate to severe chronic low back pain. The secondary objectives are to investigate the dose-response relationship of three dose levels of bicifadine, to evaluate the clinical meaningfulness of bicifadine efficacy, to evaluate the effect of bicifadine on function and general quality of life, to describe the population pharmacokinetics of bicifadine in patients with chronic low back pain, and to evaluate safety following discontinuation of bicifadine treatment.
The primary objective of the study is to evaluate the safety and efficacy of bicifadine 400 mg BID for up to one year in patients with moderate to severe chronic low back pain. The secondary objectives are to compare the long-term safety of bicifadine to standard of care therapy, to evaluate the safety of bicifadine following discontinuation of dosing, and to evaluate the safety and efficacy of lower doses of bicifadine in patients who do not tolerate bicifadine 400 mg BID.
Low back pain is a common condition, which extols a large cost to society from lost wages The Biowave System was developed by Biowave Corporation (Biowave), Norwalk, CT. Two wires emanate from the unit. The feed wire is attached to a large disposable input pad ("Feed Electrode"). The return wire is attached to a smaller pad ("Return Electrode") over the source of the pain (the treatment site). The device sends a premixed modulated envelope of two high frequency electronic wave forms ("Feed Signal") between the two electrodes. The beat frequency of the modulated envelope ("d-Frequency") is equal to the difference in frequency of the two feed signals. The location of beat frequency formation is dependent on the size and location of the two electrodes. With the configuration used in the study, the beat frequency signal is believed to form immediately ventrally to the Return electrode. The size of the volume of tissue affected can be changed and is dependent upon electrode geometry and the amplitude of the Feed Signal. The beat frequency is a low frequency blocking signal which is believed to cause a demodulation in the nerve cells and a reduction of the sodium/potassium ion exchange. As a result, the charge polarity of the nerve cell wall is prevented from changing and is therefore unable to transmit pain impulses. The size of the volume of tissue affected can be changed and is dependent upon electrode geometry and the amplitude of the Feed Signal. The objective of this study is to compare the Biowave System with TENS (a currently available treatment) and to further evaluate its efficacy for the relief of pain in patients with chronic low back pain.
Opiates such as morphine are the cornerstone medications for the treatment of moderate to severe pain. Recent evidence suggests that pain patients on chronic opioid therapy become more sensitive to pain (hyperalgesia) over time. There is also a long-standing notion that analgesic tolerance to opioids (habituation) develops during chronic use even though this phenomenon has never been prospectively studied. Our specific aims propose to prospectively test the hypotheses that; 1) Pain patients on chronic opioid therapy develop dose-dependent tolerance and/or hyperalgesia to these medications over time, 2) Opioid-induced tolerance and hyperalgesia develop differently with respect to various types of pain, 3) Opioid-induced hyperalgesia occurs independently of withdrawal phenomena, and 4) Opioid-induced tolerance and hyperalgesia develop differently based on gender and/or ethnicity. This proposed study will be the first quantitative and prospective study of tolerance and hyperalgesia in pain patients and will have important implications for the rational use of opioids in the treatment of chronic pain.
A Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Safety of ORAVESCENT Fentanyl Citrate for Management of Breakthrough Pain in Opioid-Tolerant Patients with Chronic Low Back Pain
The majority of the study consists of standard of care treatment for people with low back pain that has lasted more than three months. Half of the participants in the study will receive physical therapy from physical therapists that have received additional training in an educational technique. In order to determine if there is a difference in patient outcome when the educational technique is used, you will be asked to complete five short surveys before receiving physical therapy (10 minutes total). A sample of the physical therapy sessions using the educational technique will be videotaped. The videotape will be of the physical therapist to prove they did use the educational technique, not of you the participant in the study. You will remain anonymous and will not be used and the tape will not be used for publication or presentation purposes. You will also be asked to complete one survey after participating in physical therapy (2 minutes), and all five short surveys (10 minutes total) six weeks after your last physical therapy session. You will be put in one of 2 groups by chance (as in the flip of a coin). A computerized selection process will be used to assign participants to the study. You will not know if you are in the study group or the non-study group.
The purpose of this study is to determine whether gabapentin is efficacious as an analgesic for chronic low back pain.
The purpose of this study is to evaluate the efficacy of MK0663 for the treatment of chronic low back pain and to investigate the overall safety and tolerability over four weeks of treatment.
This is a pilot randomized trial intended to evaluate the effectiveness of acupuncture, chiropractic and massage for chronic back pain in older and younger adults.
