HORSHAM, Pa.--(BW HealthWire)--March 29, 2000
Cell Pathways, Inc. (Nasdaq:CLPA) today announced that it has completed enrollment in an open-label Phase II clinical study of Aptosyn(TM) as a treatment for precancerous colon polyps in children with familial adenomatous polyposis (FAP).
The study will investigate whether Aptosyn(TM) reduces the number of polyps in these children after one year of treatment. All participants receive a baseline colonoscopy at enrollment, and a second colonoscopy following one year of therapy with Aptosyn(TM). Following the one-year trial, all participants are eligible to continue on treatment as part of extension studies.
"After obtaining initial safety data from a small number of pediatric patients, we expanded enrollment in this study to include a total of twenty children with FAP, each of whom has colon polyps," commented Rifat Pamukcu, M.D., chief scientific officer and senior vice president of research and development. "Normally, these patients require surgical removal of most of their colon as teenagers or young adults to reduce their risk of colon cancer. We hope to see a stabilization in polyp formation followed by a reduction in the number of polyps in these young patients, with the subsequent goal of preventing or delaying the need for surgery. We are also considering additional clinical trials in this pediatric population. The search for an effective medical treatment for these young patients was the impetus for the founding of Cell Pathways over a decade ago."
About FAP
FAP is a relatively rare hereditary condition characterized by the development of hundreds to thousands of adenomatous polyps in the colon and rectum during adolescence and early adulthood. Experts consider adenomatous polyps to be precursor lesions to colorectal cancer. Left untreated, virtually all patients with FAP develop colorectal cancer by age 40-50. There are currently no drugs approved for prevention of polyps in FAP, and these patients have very few disease management options.
Aptosyn
Aptosyn(TM) (exisulind) is the first product candidate from a novel class of compounds under development by Cell Pathways, called selective apoptotic anti-neoplastic drugs (SAANDs). SAANDs inhibit cyclic GMP phosphodiesterase and selectively induce apoptosis (programmed cell death) in abnormally growing precancerous and cancerous cells. Because SAANDs do not induce apoptosis in normal cells, they do not produce the serious side effects normally associated with traditional chemotherapeutic agents. SAANDs also do not inhibit cyclooxygenase (COX I or COX II) and have not exhibited the gastric and renal toxicities reported to be associated with non-steroidal anti-inflammatory drugs (NSAIDs), including the COX II inhibitors.
A New Drug Application for Apotsyn(TM) as a treatment for patients with familial adenomatous polyposis, a precancerous condition that often leads to colon cancer, is currently under review by the U.S. Food and Drug Agency (FDA). The compound is also undergoing further clinical evaluation in a variety of additional precancer and cancer indications.
