What You Need to Know Before You Apply

What is the purpose of this trial?

This randomized pilot clinical trial studies high-dose or low-dose vorinostat in combination with carboplatin or paclitaxel in treating patients with advanced solid tumors. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving different doses of vorinostat together with carboplatin or paclitaxel may kill more tumor cells.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you cannot be on other investigational drugs or have used valproic acid. You also need to have stopped chemotherapy or radiotherapy at least 4 weeks before joining the study.

Is the combination of Vorinostat and chemotherapy safe for humans?

Vorinostat, when used with chemotherapy drugs like carboplatin and paclitaxel, has been studied for safety in humans. Common side effects include fatigue, nausea, vomiting, diarrhea, and low platelet counts, with some serious cases of blood clots. However, no drug-related deaths were reported in the studies. ^{1 2 3 4 5}

What makes the drug Vorinostat combined with Carboplatin and Paclitaxel unique for treating advanced cancer?

The combination of Vorinostat with Carboplatin and Paclitaxel is unique because Vorinostat is a histone deacetylase inhibitor, which can modify gene expression and potentially enhance the effectiveness of chemotherapy. This combination aims to improve treatment outcomes by targeting cancer cells more effectively than standard chemotherapy alone. ^{6 7 8 9 10}

What data supports the effectiveness of the drug Vorinostat (SAHA) in combination with chemotherapy for advanced cancer?

Vorinostat (SAHA) has shown potential effectiveness in treating T-cell lymphoma and possibly breast cancer, as well as having antiproliferative effects in non-small cell lung cancer with specific mutations. It is also being evaluated in combination with other drugs for acute leukemias, suggesting its potential as part of a combination therapy for various cancers. ^{4 11 12 13 14}

Published Research Related to This Trial

Vorinostat (SAHA) shows varying effectiveness in treating breast cancer, with some tumors and cell lines being resistant due to differences in gene expression related to cell adhesion and glutathione metabolism.

Depleting glutathione with buthionine sulfoximine (BSO) can enhance the effectiveness of SAHA, suggesting that evaluating antioxidant gene expression may help predict which tumors will respond to this treatment.

In a phase I/II trial involving 33 patients with EGFR-mutated non-small cell lung cancer (NSCLC) who progressed after tyrosine kinase inhibitors, the combination of vorinostat and erlotinib was found to be safe, with a maximum tolerated dose established for the treatment regimen.

Despite the safety of the drug combination, the study reported no significant therapeutic responses, with a progression-free survival rate of only 28% at 12 weeks, indicating that this treatment may not be effective for patients who have already progressed on other therapies.

A sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay was developed to accurately measure vorinostat and its metabolites in human serum, with a lower limit of quantitation of 3.0 ng/ml for each analyte.

This assay is currently being utilized in at least 12 clinical studies, highlighting its importance in evaluating the pharmacokinetics and therapeutic effects of vorinostat as an antineoplastic agent.

Vorinostat, when used sequentially before cytosine arabinoside (ara-C), showed mostly synergistic effects in killing leukemia cells, suggesting a promising treatment strategy for acute leukemias.

The combination of vorinostat with etoposide was found to be additive to synergistic, especially when etoposide was administered after vorinostat, indicating that the timing of drug administration is crucial for maximizing therapeutic efficacy.

Vorinostat, the first FDA-approved HDAC inhibitor, has shown safety and efficacy in treating cutaneous T-cell lymphoma (CTCL) with an overall response rate of 24-30% in advanced, refractory cases during Phase II trials.

Common side effects of vorinostat include gastrointestinal issues, fatigue, and thrombocytopenia, with thrombosis being the most serious adverse event reported.

Vorinostat, a histone deacetylase inhibitor, was found to be safe and tolerable in a phase 1 study involving 41 patients with various types of leukemia and myelodysplastic syndromes, with a maximum tolerated dose of 200 mg twice daily or 250 mg thrice daily.

The treatment led to hematologic improvements in 7 patients, including 2 complete responses, and increased histone acetylation was observed, suggesting its potential efficacy in treating acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS).

Vorinostat, a histone deacetylase inhibitor, did not cause maternal toxicity or major fetal malformations in Sprague-Dawley rats and Dutch Belted rabbits, indicating a relatively safe profile during pregnancy at lower doses.

However, at high doses, vorinostat was associated with developmental toxicity, such as decreased fetal weight and skeletal variations, suggesting that while it is generally safe, caution is needed with higher dosages due to potential adverse effects.

VP 16-213, a new semisynthetic epipodophyllotoxin, demonstrated clinically valuable antitumor activity in a phase II trial involving 33 patients with solid tumors and acute leukemias, particularly showing promising results in patients with oat cell carcinoma of the lung.

The drug was generally well tolerated, but it commonly caused side effects like leukothrombopenia and hair loss, indicating a need for further studies to optimize its dosage and explore its use in combination therapies.

VP 16-213, a new drug derived from podophyllotoxin, shows significant effectiveness against small-cell bronchial carcinoma and may also be beneficial for other lung tumors, testicular teratomas, and certain leukemias, making it a promising treatment option.

The drug's mechanism of action is not fully understood, but it appears to cause the most damage to cancer cells during specific phases of the cell cycle, and prolonged administration may enhance its effectiveness compared to single doses, with no long-term toxicity reported.

In a multicenter phase II study involving 50 patients with advanced ovarian cancer who had previously undergone platinum-based chemotherapy, the combination of paclitaxel and carboplatin showed an overall response rate of 43%, indicating its efficacy in this patient population.

The treatment was generally safe, with myelosuppression being the most common severe side effect, but only one case of neutropenic fever was reported, suggesting that this regimen can be administered safely to outpatients.

Primary chemotherapy for advanced ovarian cancer typically involves a combination of platinum agents (like carboplatin or cisplatin) and taxanes (such as paclitaxel or docetaxel), leading to a favorable response in 60% to 80% of patients.

Future research aims to integrate new cancer-fighting drugs into standard treatments to improve effectiveness, enhance quality of life, and extend survival for patients.
