Hebbie Posted June 8, 2004 Share Posted June 8, 2004 Telik drug shrinks ovarian, lung tumors in trials Reuters Health Posting Date: June 8, 2004 Last Updated: 2004-06-08 16:46:13 -0400 (Reuters Health) NEW ORLEANS (Reuters) - Patients with lung and ovarian cancers who had previously failed to benefit from standard treatments saw their tumors shrink considerably when an experimental drug made by Telik Inc. was added to their chemotherapy, researchers report. Results of three small mid-stage trials of the medicine funded by Telik were presented at the annual meeting here of the American Society of Clinical Oncology in New Orleans. One trial involved 21 patients with ovarian cancer who were given the drug, called Telcyta, in combination with carboplatin. The patients had failed at least one round of chemotherapy. After about one year of treatment, 56% of the patients saw their tumors shrink by at least 50%, with no sign of cancer remaining in three of the patients, said Dr. John Kavanagh, an oncologist at the University of Texas M.D. Anderson Cancer Center in Houston. Telcyta was not tested by itself against carboplatin, a drug that Telik chief executive Michael Wick said typically produces shrinkages in only about 10% of such patients with advanced ovarian cancer. "The data are so strong that we have decided to begin a late-stage trial this summer" testing Telcyta in perhaps 200 such ovarian cancer patients, Wick said in an interview. Another trial described on Saturday involved 21 ovarian cancer patients given Telcyta in combination with liposomal doxorubicin (Doxil), a Johnson & Johnson drug typically given only to patients who have failed many rounds of chemotherapy. All patients had previously taken platinum-based chemotherapy, typically carboplatin. About 46% of patients getting the combination saw their tumors shrink, and with no side effects beyond those typically seen with Doxil by itself. Doxil as a stand-alone treatment typically shrinks tumors in only about 12% of patients, Wick said. The third phase II trial involved 30 patients with lung cancer, most of whom had failed one round of chemotherapy. They were given Telcyta in combination with Taxotere, an Aventis SA drug that is a standard treatment. Twenty-seven percent of patients taking the combination of drugs saw their tumors shrink, including one patient with no further signs of cancer, with patients experiencing side effects similar to those typically seen with Taxotere alone. Wick said the results were impressive because Taxotere, by itself, usually shrinks tumors in only about 3% to 8% of such lung cancer patients. Telcyta is now being evaluated in a larger phase III study for lung cancer. Quote Link to comment Share on other sites More sharing options...

john Posted June 9, 2004 Share Posted June 9, 2004 I think you have to very wary whenever a CEO opens his mouth about a drug Wick the CEO of Telik says that Taxotere only shrinks tumors in 3-8% of patients. I don't think it would have been approved if it worked in so few people. Also the quote below says there is a response in 20% of patients I don't want to dampened anyones hopes, but if you look for clinical trials or drugs to try make sure it is the best possible The overall response rate in the docetaxel group was 20 percent. The overall response rate is the sum of the complete and partial response rates. A complete response is defined as a complete disappearance of clinical and x-ray signs of the cancer, while a partial response refers to a 50 percent or greater decrease in measurable tumor size.

Elaine Posted June 9, 2004 Share Posted June 9, 2004 John and All: There's also an interesting sentence in the article: "The patients had failed at least one round of chemotherapy." My question is this: Is isn't it the chemo that fails and NOT the patient? Isn't this an example of what some of us were talking about last week--patients feeling responsible not only for their cancer, but for their response to treatment. It seems to be ia lot of "cultural" blame heaped on Cancer fighters. elaine Quote Link to comment Share on other sites More sharing options...
