SECAUCUS, N.J. and SOUTH SAN FRANCISCO, Calif., Oct. 18 /PRNewswire-FirstCall/ -- AlgoRx Pharmaceuticals, Inc. and Corgentech Inc. today announced positive data from a Phase 2 trial of ALGRX 4975 in patients with Morton's neuroma-a painful neuropathy of the foot. In the 58-patient randomized, double-blind, placebo-controlled clinical trial, conducted at two study centers in the United States, the group consisting of 30 subjects who received ALGRX 4975 (100 micrograms) by a single injection into the neuroma had statistically significant decreases in their foot pain four weeks after the single administration of study drug. The mean baseline pain score (0-10 Numeric Rating Scale) was 5.7 for subjects in each treatment group. Pain scores were reduced at four weeks following the single administration of ALGRX 4975, with a mean pain score of 2.1 (63 percent reduction in pain) compared to 3.5 (38 percent reduction in pain) in subjects treated with placebo (p=0.0188). Additionally, ALGRX 4975 was well tolerated and did not demonstrate any significant safety issues.
"The strong pain relief demonstrated in this Phase 2 trial of ALGRX 4975 contributes to the growing body of data which demonstrate that this product candidate may be a safe and effective drug for a variety of moderate to severe pain syndromes," stated Ronald M. Burch, M.D., Ph.D., chief executive officer of AlgoRx. "ALGRX 4975 has been evaluated in more than 340 patients in several clinical trials across multiple post-surgical, neuropathic and musculoskeletal pain indications. In patients with moderate to severe pain, ALGRX 4975 has demonstrated significant pain relief, giving us confidence that this drug may have the potential to be used in many pain syndromes."
"We are pleased to report positive data from another product candidate in the pain management pipeline. This is the second set of good clinical trial data reported in less than two weeks, as we announced positive Phase 3 data from ALGRX 3268 earlier this month. This progress gives us additional confidence that our proposed merger with AlgoRx will increase the value of Corgentech for our stockholders as we continue to move decisively toward product commercialization," said John P. McLaughlin, chief executive officer of Corgentech. "We believe that ALGRX 4975 will have the ability to offer pain management benefits in a variety of post-surgical and other indications. The post-operative pain market in the United States alone is more than $1.7 billion, and we believe that there is an excellent opportunity for a safe and long-acting pain reliever which could reduce the need for opioid medications."
About ALGRX 4975 and the Market Opportunity for a Fast-Acting Local Anesthetic
ALGRX 4975, a VR1 agonist, is being developed for site-specific, moderate to severe pain. ALGRX 4975 is a C-neuron anesthetic, based on capsaicin. It is long-acting, providing pain relief to many patients for weeks or months after a single treatment. The product is administered locally at the site of pain and selectively reduces pain in nerve endings so does not affect other nerve fibers important for other sensory or motor skills. Phase 2 clinical trials are currently underway for post-surgical pain following a variety of surgeries including hernia repair, total knee replacement and cholecystectomy. In addition to the study for Morton's neuroma, a Phase 2 trial for another non-surgical procedure, tendonitis, is underway.
ALGRX 4975 has demonstrated its potential in multiple clinical studies to impact pain across neuropathic, post-surgical and musculoskeletal pain conditions. Opioid drugs, such as morphine, are used to service many of these conditions but are associated with significant side effects including respiratory depression, euphoria, and nausea and vomiting during acute use, and constipation and physical dependence during chronic use. ALGRX 4975 has not demonstrated similar side effects. Additionally, it has been shown that pain in the hospital is associated with increased length of stay, longer recovery times and poorer patient outcomes. By safely decreasing the patient's level of pain, ALGRX 4975 may have the potential to reduce a patient's length of hospital stay as well their need for opioids.
About Morton's Neuroma
Morton's neuroma is a painful condition of the foot that typically occurs as a result of wearing high narrow shoes, running, or spending considerable time standing each day. The thickening of the nerve tissue (neuroma) seems to occur in response to pressure or injury to one of the nerves that lead to the toes, resulting in pain and numbness that can make walking unbearable. Morton's neuroma is difficult to treat, so patients are often referred to foot specialists (podiatrists). In most patients, orthotics or analgesics such as aspirin-like drugs and opioids have limited effectiveness. More aggressive treatments, including surgical intervention to remove the nerve, are sometimes employed, but leave patients with permanent numbness in the foot.
