Filter by:Primary Objective: To assess the efficacy of SAR292833 versus placebo in reducing pain intensity associated with chronic peripheral neuropathic pain using 11-point numerical rating scale (NRS). Secondary Objectives: - To compare the effects of SAR292833 with placebo on the change of neuropathic pain symptoms versus baseline Neuropathic Pain Symptoms Inventory (NPSI); - To evaluate the effects of SAR292833 in comparison to placebo on the change in pain intensity of mechanical allodynia; - To investigate the safety and tolerability of SAR292833 in comparison to placebo; - To investigate the pharmacokinetics (PK) and the relationships between main efficacy parameters or pharmacodynamic effect (PD) and pharmacokinetics (PK/PD) of SAR292833 in patients with chronic peripheral neuropathic pain.
Oxaliplatin (Ox) is part of most treatment regimens for colorectal cancer. However, it may induce side effects, such as a specific injury to peripheral nerves called neuropathy. Ox-induced neuropathy is frequently painful. The presence of pain after its administration may hamper the full chemotherapeutic treatment of patients with colorectal cancer receiving this agent. Recently, it has been suggested that the appearance of acute neuropathy after oxaliplatin (Ox) infusion could predict the distal polyneuropathy seen some months after treatment. These two adverse events related to Ox treatment probably share different mechanistic backgrounds. However, recent experimental data suggest that both types of peripheral neuropathies are able to induce central sensitization, a major step to the occurrence of chronic pain. Pregabalin is a molecule used to teat neuropathic pain since it can diminish the peripheral sensitization seen in this painful condition. Recently, it has also been shown that pregabalin can be used to treat neuropathic pain related to Ox treatment. In the present study, we will test the hypothesis that Pregabalin administrated exclusively for three days before and three days after the Ox infusion is able to prevent the occurrence of pain secondary to both the acute and chronic Ox-associated neuropathies. In the classical FLOX chemotherapeutic regimen, Ox is infused in nine sessions during a six-month period. Patients will be followed for a year and nerve conduction tests, quantitative sensory evaluation, pain, quality of life and functional scales will be used to assess the impact of this strategy in the prevention of pain. If this strategy proves to work, this information will have a major impact in the cancer prognosis of patients with colorectal cancer since Ox will be able to administer in its full dose, and will not be limited by neuropathic side effects.
The main objective of the study is to evaluate the effectiveness, safety, and tolerability of increasing doses of tapentadol prolonged release (PR) (500 mg per day) versus a combination of tapentadol PR (300 mg per day) and pregabalin (to 300 mg per day) in subjects requiring additional analgesia after titration to tapentadol PR 300 mg per day. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject reported outcomes. Since, severe low back pain with a neuropathic component, the targeted study population, is frequently treated with a combination therapy (monotherapy is often not effective enough) it is of interest to determine if tapentadol alone (combining 2 mechanisms of action in a single molecule) could be as effective as a combination of tapentadol plus pregabalin. Furthermore, the tolerability profiles of monotherapy versus combination are of interest.
The purpose of this study is to determine whether BEMA Buprenorphine is safe in the treatment of chronic pain.
In animal, the GABAergic system modulates central sensitisation, which is a key phenomenon in pain processing. The development of GABAA agonists targeting the subunits of the GABAA receptor implicated in nociception, but not the subunit implicated in sedation is attractive as it opens new perspectives of testing the role of GABAergic modulation of pain processing in human volunteers. The purpose of this subproject is to test the effect of the specific α2 and α3 agonist but sparing α1 effect TPA023 on a human model of peripheral and central sensitisation and to correlate its pharmacodynamic effect with the pharmacokinetic of the compound. The results would contribute to clarify the potential role of these α2/α3 agonist but sparing α1drugs in clinical pain conditions.
The objective of this investigation is to evaluate the safety and efficacy of long term use with Lyrica in medical practice. Also, occurrence of unknown and known adverse drug reactions (ADRs) in subjects treated with Lyrica will be monitored during the survey period, and whether an additional treatment outcome investigation and/or a post-marketing clinical study is required in the future will be determined.
The primary objective of this study is to compare the effect of CT327 to placebo against experimental induced superficial, deep and hyperalgesic pain. The secondary objectives are to elucidate the mechanisms of CT327 using experimental pain models.
This study collects post-marketing safety and efficacy surveillance data in real world clinical use of pregabalin for its approved indications in Korea.
The purpose of this study is to find out if Exalgo (r) is beneficial for the patients with neuropathic pain.
A study to investigate the analgesic efficacy of AZD2423 compared with placebo after 28 days treatment in patients with painful diabetic polyneuropathy.
