Active clinical trials for "Pain"

The investigators plan a prospective randomized study to see whether negative questions affect measures of mood, pain, or disability. A total of 175 patients will participate at Massachusetts General Hospital.

The primary objective of the study is to assess the efficacy of Intravenous (IV) BG00010 (Neublastin) in improving pain in painful lumbar radiculopathy participants when administered 3 times per week for 1 week. The secondary objectives of this study in this study population are as follows: To explore the duration of the effect of BG00010 in improving pain; To explore the dose response curve on pain reduction; To assess the safety and tolerability of BG00010; To assess the serum exposure to BG00010.

The purpose of this study is to evaluate the efficacy and safety of Relugolix (TAK-385) in patients having pain symptoms associated with uterine fibroids.

Evaluate the effectiveness of the Provant Therapy System compared to sham on pain sensitivity and nervous system response to various qualities of experimentally induced pain in the upper and lower extremities of subjects with painful peripheral diabetic neuropathy.

The study compares the analgesic efficacy of OXN PR vs placebo in opioid-naive subjects suffering from severe pain due to Bladder Pain Syndrome.

The purpose of this study is to determine whether PD 0299685 is effective in the treatment of symptoms associated with interstitial cystitis/painful bladder syndrome, such as pain, urinary urgency and frequency. At the same time assess the drug's safety and tolerability.

The purpose of the study is to assess the safety of repeated applications of QUTENZA in reducing pain intensity in subjects who have peripheral neuropathic pain due to diabetes.

Primary Total Knee joint replacement surgery is highly successful surgery for relieving pain and improving function in patients with disabling arthritis. Unfortunately, like all biomedical devices, prosthesis failure is a complication of knee replacement surgery that leads to disabling pain, stiffness and loss of function. Approximately 1% of the knee replacements fail every year leading to a 20% failure rate over 20 years. The common causes of failure of prosthetic joint are infection, loosening, trauma or wear of the prosthesis. Currently, a revision surgery is the best option for long term pain relief (analgesics or other pain medications are options but are of limited benefit). Surgery may not be feasible in patients due to advancing age, other medical conditions and surgical/technical difficulties or patient's choice. In addition, the results from revision surgery are not as good as the initial knee joint surgery. Therefore, there is a great need for a novel, targeted therapy that provides an option to patients who are unfit, unable, or unwilling to undergo surgery. In the investigators' recent pilot study, a single injection of Botulinum toxin A (Botox) in painful natural knee, ankle and shoulder joints of patients with various types of arthritis led to significant and durable improvement in pain and function and was safe to use. The investigators propose this 6-month study to compare pain relief, improvement of function and safety of an injection of Botulinum toxin compared to placebo in patients with a painful prosthetic knee joint. Both patients and investigators will be blinded to the treatment assignment to a patient until the study is completed. The investigators will assess the amount and duration of pain relief, improvement in function and short term safety of Botulinum toxin using standard validated measures. Patients will be evaluated at baseline, 2 weeks, 1-, 2-, 3-, 4- and 6-months after a single injection of either placebo or BoNT/A in the hip or knee prosthesis. The six-month follow-up is to assess the duration of meaningful pain relief. If successful, this will offer a new treatment option for patients with a chronically painful knee prosthetic joint, provide more insight into the origin and cause of pain in prosthetic joints and direct future investigations in new directions.

The purpose of this trial is to assess whether 400mg/day of lacosamide is effective in reducing pain caused by distal diabetic neuropathy. Two dose-escalation schemes for lacosamide will be used to further determine the efficacy of the "standard" scheme and to evaluate the efficacy and safety of a more rapid titration scheme. Subjects will be randomly assigned to one of three treatment groups. Subjects in two of the groups will receive lacosamide at a dose of 400mg/day, but different dose-escalation schemes will be used to reach this final dose. The third group of subjects will receive a placebo. Subjects will have a 2 in 3 (66 %) chance of getting lacosamide. The maximum lacosamide dose in this trial will be 400mg/day. The maximum treatment duration will be 18 weeks, including a two-week Pre-Treatment Phase and a 12 weeks period on a stable dose of lacosamide or placebo.

The purpose of the study is to determine if duloxetine can help patients with painful diabetic neuropathy.
