Depsipeptide in Unresectable Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck

Phase 2

Completed

Conditions: Stage IV Squamous Cell Carcinoma of the Larynx
Stage IV Squamous Cell Carcinoma of the Lip and Oral Cavity
Stage IV Squamous Cell Carcinoma of the Oropharynx
Stage IV Squamous Cell Carcinoma of the Hypopharynx

Interventions: Drug: romidepsin

Registration Number: NCT00084682

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This phase II trial is studying how well FR901228 works in treating patients with unresectable recurrent or metastatic squamous cell carcinoma (cancer) of the head and neck. Drugs used in chemotherapy such as FR901228 work in different ways to stop tumor cells from dividing so they stop growing or die.

Detailed Description: PRIMARY OBJECTIVES:

I. To evaluate the rate of disease control (i.e., achievement of complete response, partial response, or stable disease) of the single agent depsipeptide in patients with unresectable recurrent or metastatic squamous cell carcinoma of the head and neck.

SECONDARY OBJECTIVES:

I. To evaluate the duration of response, time to progression, and overall survival for patients with incurable head and neck cancer treated with depsipeptide.

TERTIARY OBJECTIVES:

I. To determine the extent of histone hyperacetylation in peripheral blood mononuclear cells (PBMCs) as a readout of depsipeptide activity before and after depsipeptide administration, to correlate this activity with observed histone hyperacetylation in tumor and mucosal cells, and to correlate extent of depsipeptide activity with tumor response.

II. To determine depsipeptide-induced changes in the gene expression profile of tumor cells from biopsies of accessible tumor tissue and of mucosal cells from transepithelial oral brush biopsies using cDNA microarrays containing 28,000 clones, and to correlate these changes with extent of histone hyperacetylation observed in PBMCs and tumor tissues.

III. To determine depsipeptide-induced changes in methylation of candidate genes in tumor cells and oral mucosa epithelia.

IV. To demonstrate altered expression of signaling and cell cycle-related proteins in tumor tissue in response to depsipeptide.

OUTLINE: This is a multicenter study.

Patients receive FR901228 (depsipeptide) IV over 4 hours on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 14

Inclusion Criteria

histologically or cytologically confirmed squamous cell cancer of the head and neck (MedDRA code 90002024), excluding nasopharyngeal primaries, which is unresectable or metastatic; the disease must be incurable with surgery or radiation therapy; the tumor should preferably be present at the primary site, and it must be accessible to planned biopsy methods
Measurable disease by RECIST,
May have received any number of prior systemic chemotherapy regimen for unresectable, recurrent or metastatic disease; if the only site of measurable disease is a previously irradiated area, the patient must have documented progressive disease or biopsy-proven residual carcinoma; persistent disease after radiotherapy must be biopsy-proven at least 8 weeks after the completion of radiotherapy
Life expectancy of greater than 3 months
Normal organ and marrow function as defined by the following labs performed =< 2 weeks of study entry:
Leukocytes ≥ 3,000/uL
Absolute Neutrophil Count ≥ 1,500/uL
Hemoglobin ≥ 10 gm%
Platelets ≥ 100,000/uL
Total Bilirubin =< 1.5 X upper normal institutional limit
AST(SGOT)/ALT(SGPT) =< 2.5 X upper normal institutional limits
Creatinine within normal institutional limits OR creatinine clearance ≥ 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
PT/PTT =< 1.1X upper normal institutional limits
Calcium within normal institutional limits
CPK, Troponin within normal institutional limits
Uric Acid within normal institutional limits
Ability to understand and the willingness to sign a written informed consent document; in addition to consent for the therapy, patients must give consent to required pre- and post-therapy blood and tissue samples;

Exclusion Criteria

Patients should not have had prior therapy with depsipeptide and may not be receiving any other investigational agents or drugs known to have histone deacetylase inhibitor activity such as sodium valproate
Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
Significant cardiac disease including congestive heart failure that meets New York Heart Association (NYHA) class III and IV definitions (see Appendix II), history of myocardial infarction within one year of study entry, uncontrolled dysrhythmias, or poorly controlled angina
History of serious ventricular arrhythmia (VT or VF, > 3 beats in a row), QTc > 500 msec, or LVEF < 40%
Patients may not be co-medicated with an agent that causes QTc prolongation; - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, or psychiatric illness/social situations that would limit compliance with study requirements
Not pregnant or lactating
History of HIV infection

Study Type: INTERVENTIONAL

Arm && Interventions

Group	Intervention	Description
Treatment (romidepsin)	romidepsin	Patients receive FR901228 (depsipeptide) IV over 4 hours on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures

Name	Time	Method
Disease Control (i.e., Achievement of Complete Response, Partial Response, or Stable Disease)	Up to 2 years	Tumor response was assessed every eight weeks per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions as assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR. Stable disease (SD) was defined as having no evidence of response (CR or PR) as best response to therapy, and no evidence of disease progression (appearance of new lesions or \>/= 30% increase in target lesions) at 8 weeks.

Secondary Outcome Measures

Name	Time	Method
Duration of Response	Up to 2 years
Time to Progression	Up to 2 years	All time to event endpoints will be evaluated using Kaplan Meier estimates and survival curves will be generated based on these estimates.
Overall Survival	Up to 2 years	All time to event endpoints will be evaluated using Kaplan Meier estimates and survival curves will be generated based on these estimates. One and two-year survival and median survival time (if attained) will be estimated and reported with 95% confidence limits. If the sample sizes are sufficient, subgroup analysis based on baseline factors will be performed using the log rank test to compare survival curves.
