Chemo combo highly effective for mesothelioma

22 Jul 2008 by under News, Research/Treatment

Researchers in Denmark have discovered a chemotherapy combination that is proving to be highly effective for people with non-resectable malignant mesothelioma, according to a recent report on The study was published in a June issue of the British Journal of Cancer.

According to the report, the study evaluated a regimen of Navelbine (vinorelbine) and () for the treatment of 54 patients with newly diagnosed non-resectable mesothelioma. The median number of cycles of chemotherapy administered was four. There were two complete responses and 14 partial responses.

The median survival was 16.8 months, and the median time to tumor progression was 7.2 months. The one-year survival was 61 percent, the two-year survival was 31 percent, and the three-year survival was 4 percent.

The authors of the study say these results are as good as or better than currently used combinations for treatment of mesothelioma.

Clinical trial for mesothelioma at NY hospital

8 Jul 2008 by under News, Research/Treatment

A New York medical center specializing in the treatment of mesothelioma has announced a new clinical trial accepting patients. The Mesothelioma Center within the at NewYork-Presbyterian Hospital and Columbia University Medical Center is launching a program of targeted radiation and chemotherapy protocol for pleural mesothelioma, a cancer of the lung’s lining that is almost always caused by previous exposure to asbestos.

It is hoped the new treatment will replace or delay the need for the standard treatment in these cases, a pleural pneumonectomy, which involves removal of the lung and which can be extremely debilitating to patients.

According to a press release from the medical center, Dr. Robert Taub, the study’s principal investigator, director of the Mesothelioma Center at NewYork-Presbyterian/Columbia and professor of clinical medicine at Columbia University College of Physicians and Surgeons, says, “Current surgical and chemotherapy treatments of patients with malignant pleural mesothelioma are unsatisfactory, and have not been shown to significantly prolong survival. In this study, we will investigate whether a combination of chemotherapy and radiation targeted directly at the lung’s lining can improve outcomes while avoiding surgery. In addition, this approach has shown to have minimal toxic side effects compared to systemic chemotherapy.”

The Mesothelioma Center is the only one nationwide that is offering this experimental therapy to treat pleural mesothelioma.

The study is being conducted at the Mesothelioma Center within the Herbert Irving Comprehensive Cancer Center at NewYork-Presbyterian Hospital and Columbia University Medical Center. According to the release, participating patients will receive several rounds of targeted chemotherapy using the drugs cisplatin and doxorubicin via surgically implanted catheters. Some patients will be randomly selected to receive additional systemic (intravenous) chemotherapy using the drugs cisplatin and pemetrexed. All patients will receive targeted radiotherapy using the P-32 radioisotope.

Patients may elect to receive additional surgical treatment, including removal of the affected lung lining or lung. Subsequently, patients will be offered outpatient systemic chemotherapy with cisplatin and pemetrexed.

Merck begins vorinostat Phase III meso trial

10 Jun 2008 by under News, Research/Treatment

Merck & Co. announced May 27 that it is proceeding to Phase III clinical trials for vorinostat, which is currently marketed under the name Zolinza. The drug is an oral histone deacetylase (HDAC) inhibitor, and is being tested in patients with advanced malignant pleaural mesothelioma previously treated with systemic chemotherapy. Merck is currently enrolling patients in the Phase III trial.

According to the company’s news release, available in its entirety on the Mesothelioma Applied Research Foundation web site, the trial is moving forward after a favorable review of currently available safety and efficacy data from the Phase II portion of the study. This is an international study, expected to enroll 660 patients with testing centers in the United States, Belgium, Germany, the Netherlands, New Zealand, Spain, Sweden and the United Kingdom. It will be an ongoing randomized, double-blind, placebo-controlled trial.

Information provided by Merck says the trial will examine the safety, tolerability and anti-tumor activity of oral vorinostat with best supportive care as compared to best supportive care plus placebo in patients with advanced mesothelioma who have failed or are intolerant to prior chemotherapy, icnlucing pemetrexed in combination with either cisplatin or carboplatin.

Primary endpoints of the Phase III trial include overall survival as well as characterization of the overall safety and toxicity of vorinostat in patients with advanced malignant mesothelioma.

Patients interested in more information about the trial and how to enroll should call toll-free 1-866-890-6619 (in the U.S.) and 1-888-577-8839 (outside the U.S.) or visit the Merck Cancer Trials web site.

Zolinza is currently approved in the U.S. for treatment of cutaneous manifestations in patients with cutaneous T-cell lymphoma (CTCL) who have progressive, persistent or recrruent disease on or following two systemic therapies.

New mesothelioma treatment research promising

23 May 2008 by under News, Research/Treatment

The results of a new study, published on 7th Space Interactive, show that the use of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in combination with (CDDP), has been shown to exert an anti-tumoral effect on cells.

Most people are familiar with the nonsteroidal anti-inflammatory drug naproxen, which is found in their common pain relievers like Aleve.

Wikipedia defines a nonsteroidal anti-inflammatory drug as “drugs with analgesic, antipyretic and, in higher doses, anti-inflammatory effects – they reduce pain, fever and inflammation. The term “non-steroidal” is used to distinguish these drugs from steroids, which (among a broad range of other effects) have a similar eicosanoid-depressing, anti-inflammatory action. As analgesics, NSAIDs are unusual in that they are non-narcotic. The most prominent members of this group of drugs are aspirin, ibuprofen, and naproxen partly because they are available over-the-counter in many areas.”

The NSAID used in this study is piroxicam.

The study used two mesothelioma cell lines, and explored the effects of piroxicam alone, as well as in conjunction with CDDP. The report says that “treatment with piroxicam or CDDP alone altered the cell cycle phase distribution as well as the expression of some cell cycle regulatory proteins in both cell lines” and that “these effects were increased, even if in a not completely overlapping manner, after treatment with the association of piroxicam and CDDP.”

The report notes that “the mechanisms through which NSAIDs regulate the cell cycle as well as the signal pathways involved in the growth inhibition, remain unclear” but says the findings from this recent study “hold promise in the treatment of mesothelioma.”

The study was orginally published in the Journal of Transitional Medicine.
