Suberoylanilide Hydroxamic Acid (Vorinostat, MK-0683) Versus Placebo in Advanced Malignant Pleural Mesothelioma (MK-0683-014)

• Status: Completed
• Trial end date: 2011-11-21
• Target enrollment: 0
• Participant gender: All

Summary

The goal of this study is to assess the efficacy and safety of an oral investigational drug suberoylanilide hydroxamic acid (vorinostat, MK-0683) compared to placebo, in the treatment of participants with advanced malignant pleural mesothelioma who have failed at least one prior chemotherapy regimen. The primary hypotheses are the following: (1) vorinostat improves overall survival (OS) compared to placebo (2) vorinostat is generally safe and well tolerated.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Merck Sharp & Dohme Corp.
• Treatments: Vorinostat

Criteria

Inclusion Criteria :

• 18 years or older with confirmed diagnosis of malignant pleural mesothelioma

• In countries where pemetrexed is an approved mesothelioma treatment, the participant's disease has progressed or relapsed following treatment with at least one prior chemotherapy regimen with pemetrexed and either cisplatin or carboplatin OR in countries where pemetrexed is not approved for mesothelioma, the participant's disease has progressed or relapsed following treatment with at least one prior chemotherapy regimen OR pemetrexed is not the preferred therapy for the participant and the participant's disease has progressed or relapsed following treatment with at least one prior chemotherapy regimen

• Received no more than 2 prior systemic therapy regimens

• Karnofsky performance scale status of ≥70

• Has adequate bone marrow, liver, and kidney function and adequate coagulation (per prespecified laboratory values)

Extension Phase Inclusion Criteria:

• Participants who are receiving treatment with vorinostat and have not experienced progression of mesothelioma

• Randomized to the placebo arm and: 1) have a Karnofsky performance scale status of ≥70; and 2) have adequate bone marrow, liver, and kidney function and adequate coagulation (per prespecified laboratory values)

• Randomized to vorinostat and have discontinued study therapy for reasons other than progression of mesothelioma, if the investigator is of the opinion that the potential benefit outweighs potential risks associated with using vorinostat

Exclusion Criteria:

• Has an active infection for which they received treatment with intravenous antibiotic, antiviral, or antifungal medications within 2 weeks of the start of study drug.

• Has a "currently active" second malignancy; a malignancy is not considered "currently active" if participants have completed therapy for the second malignancy and are disease free from prior malignancies for >5 years

• Has uncontrolled brain metastases

• Has a known human immunodeficiency virus (HIV) infection or HIV-related malignancy

• Is pregnant or breast feeding

• Has a history of gastrointestinal surgery or other procedures that might interfere with the absorption or swallowing of the study drug
