Trial Description


Drugs used in chemotherapy, such as vorinostat, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether vorinostat is more effective than a placebo in treating malignant mesothelioma.

This randomized phase III trial is studying vorinostat to see how well it works compared to placebo in treating patients with progressive or relapsed advanced malignant mesothelioma.


Eligibility criteria include the following:

     At least 18 years old
     Cancer did not respond to or came back after one or two previous treatment regimens that included pemetrexed and cisplatin or carboplatin
     At least 4 weeks since chemotherapy or radiation therapy

Final eligibility for a clinical trial is determined by the health professionals conducting the trial. For more details about the eligibility requirements for this trial and the treatment or intervention, refer to the Health Professional version of the trial summary.


Patients will be randomly assigned (have an equal chance of being placed) to one of two treatment groups.

Patients in group one will receive vorinostat by mouth twice a day 3 days a week. Treatment may continue for as long as benefit is shown.

Patients in group two will receive a placebo by mouth twice a day 3 days a week. Treatment may continue for as long as benefit is shown.

Quality of life will be assessed before beginning treatment, every 3 weeks for up to 6 months during treatment, within 1 month after finishing treatment, and every 2 months thereafter. After finishing treatment, patients will be evaluated within 1 month and every 2 months thereafter.
