Trial Outcomes & Findings for Potentiation of Cetuximab by Tregs Depletion With CSA in Advanced Head & Neck Cancer (NCT NCT01581970)

NCT ID: NCT01581970

Last Updated: 2019-09-11

Results Overview

The number of patients without disease progression two years out from study enrollment. Progression of disease is defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria and is as at least a 20% increase in size of the lesion(s) being followed and/or the appearance of one or more new lesions.

Measure
Cetuximab/Low Dose Cyclophosphamide
Safety population as defined by all patients receiving at least one treatment with cyclophosphamide on Day 1. Cyclophosphamide: Patients will be given oral cyclophosphamide 50 mg twice daily to be self-administered starting the first day of therapy with weekly cetuximab for 12 weeks or until disease progression. Cetuximab: The initial dose of cetuximab 400 mg/m\^2 is administered over 120 minutes followed by weekly infusions of cetuximab 250 mg/m\^2 intravenously (IV) over 60 minutes.

The ratio of Tregs to effector cells (NK cells, CD 8+ lymphocytes, macrophages/monocytes) in tumor tissue as measured by immune-histochemistry (IHC) of tumor tissue for all Participants. Measure of central tendency was collected but the data is not accessible anymore because PI left institution and did not respond to requests for data.

Aggregate Ratio of Tregs to Effector Cells for All Participants
0.112 ratio

SECONDARY outcome

Timeframe: 6 Weeks Post Treatment with Cyclophosphamide

Population: Measure of central tendency could not be used as the data was not originally reported in this manner and is not accessible anymore because the PI left institution and did not respond to requests for data.

the Ratio of Tregs to NK cells in peripheral blood as measured by flow cytometry for all Participants. Measure of central tendency was collected but the data is not accessible anymore because the PI left institution and did not respond to requests for data.

SECONDARY outcome

Timeframe: Comparison from Baseline to Week 6 and Week 12

Population: At this point, the data is not able to be analyzed because the PI left the institution and did not respond to requests for data.

Comparison of health related quality of life scores as measured by FACT-G: Functional Assessment of Cancer Therapy - General (constitutes the core of all subscales; the FACT-G can be used with patients of any tumor type)questionnaire. At this point, the data is not able to be analyzed because the PI left the institution and did not respond to requests for data.
