About this study
Official title: A Phase II Clinical Study of Hydralazine and Valproic Acid in Combination With Neoadjuvant Cytotoxic Chemotherapy in Stage IIB and IIIA Breast Carcinoma
Aberrant DNA methylation and histone deacetylation participate in cancer development and progression, as epigenetic alterations are common to breast cancer, in this phase II study, the demethylating hydralazine plus the HDAC inhibitor magnesium valproate will be added to neoadjuvant doxorubicin and cyclophosphamide in locally advanced breast cancer to assess their safety and biological efficacy.
Read the detailed description
Eligible patients after signing the informed consent and will undergo study evaluation and then typed for acetylator phenotype before being treated with hydralazine at 182 mg for rapid-, or 83 mg for slow-acetylators, and magnesium valproate at 30 mg/kg, starting from day -7 until chemotherapy ends. Chemotherapy will consists in a regimen of four cycles of doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2 every 21 days, followed by surgery to assess the pathological response. Adjuvant radiation and additional treatment will be done in off-protocol basis according to standard institutional policies. Blood samples and core-needle biopsies will be taken from primary breast tumors at diagnosis and at day 8 of treatment with hydralazine and valproate. Global cytosine content (global DNA methylation) and histone deacetylase activity will be assessed in peripheral blood DNA. The transcriptional profile in the primary breast tumor before and after treatment will also be analyzed as well as the plasma levels of hydralazine and valproic acid.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Hydralazine and magnesium valproate administration and Core-needle biopsy of the breast in people with Locally Advanced Breast Cancer, run by National Institute of Cancerología at 1 site in Mexico.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 3 Nov 2006. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Global DNA methylation. The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00395655, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2006.
