What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new mix of four medicines to treat tumors that are hard to treat with usual methods. The goal is to find the safest dose and see if this combination can effectively fight these tough tumors.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you cannot take any other cancer treatments or certain drugs like valproic acid for at least 2 weeks before joining. If you're on corticosteroids for a CNS tumor, your dose must be stable or decreasing for 7 days before starting the trial.

Is vorinostat safe for use in humans?

Vorinostat has been studied in humans, and common side effects include mild to moderate diarrhea, nausea, fatigue, and loss of appetite. More severe side effects can include significant fatigue, low platelet counts, and severe diarrhea, but no deaths related to the drug were reported in the studies. ^{1 2 3 4 5}

What makes the drug Vorinostat unique for cancer treatment?

Vorinostat is unique because it is a histone deacetylase inhibitor (HDACi) that can regulate gene expression and induce cancer cell death, and it is being explored for use in combination with chemotherapy for various cancers, including breast cancer and acute leukemias. Its mechanism of action and potential to enhance the effects of other cancer drugs make it a novel option compared to standard treatments. ^{1 4 5 6 7}

What data supports the effectiveness of the drug Vorinostat in cancer treatment?

Vorinostat, a drug that affects how genes are turned on and off, is already approved for treating T-cell lymphoma and shows potential in treating breast cancer and acute leukemias. It has also been studied in combination with other drugs for non-small cell lung cancer, suggesting it may help in various cancer types. ^{4 5 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Vorinostat

Trial Overview The study tests the highest safe dose of vorinostat combined with vincristine, irinotecan, and temozolomide in children and young adults. It aims to determine side effects, impact on tumor cell molecules, and overall treatment effectiveness against stubborn tumors.

How Is the Trial Designed?

Group I: Vorinostat Experimental Treatment 1 Intervention

The first cycle of chemotherapy will not include the experimental agent vorinostat. This first cycle will be used to determine whether the patient can tolerate the chemotherapeutic backbone without developing a DLT. Cycle 1 * Vincristine: 1.5 mg/m2/day (maximum dose 2 mg) IV Days 1 and 8 over 1-15 minutes. * Temozolomide: 125 mg/m2/day PO Days 1-5. * Irinotecan: 50 mg/m2/day IV Days 1-5 over 60 minutes. * Cefixime: 8 mg/kg/day (maximum dose 400 mg) PO. Begin 2 days prior to irinotecan therapy and continue through Day 8. Cycles 2-12 * Vincristine: 1.5 mg/m2/day (maximum dose 2 mg) IV Days 1 and 8 over 1-15 minutes. * Temozolomide: 125 mg/m2/day PO Days 1-5. * Irinotecan: 50 mg/m2/day IV Days 1-5 over 60 minutes. * Cefixime: 8 mg/kg/day (maximum dose 400 mg) PO. Begin 2 days prior to irinotecan therapy and continue through Day 8. * Vorinostat: Dose per escalation schema daily Days 1-5. * Vorinostat will not be administered during Cycle 1.

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.

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.

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.

Vorinostat's solubility was significantly enhanced when complexed with cyclodextrins, particularly with randomly methylated-β-cyclodextrin (RM-β-CD), which increased its solubility from 0.724 mm to 70.8 mm, making it nearly 100 times more soluble.

Molecular simulations supported these findings and suggested that using cyclodextrins could improve vorinostat's delivery methods, indicating potential for better oral absorption and parenteral delivery in future studies.

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.

In a phase I study involving 23 advanced-stage cancer patients, vorinostat was found to be safe and tolerable, with common side effects including mild to moderate nausea and fatigue.

The study revealed that a high-fat meal slightly increased the absorption of vorinostat but did not significantly impact its overall effectiveness, suggesting that vorinostat can be administered with or without food in future studies.

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).
