Brief summary

This phase II trial studies how well inolitazone dihydrochloride (efatutazone dihydrochloride) and paclitaxel work in treating patients with anaplastic thyroid cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced). Drugs used in chemotherapy, such as efatutazone dihydrochloride 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.

Detailed description

PRIMARY OBJECTIVES: I. To determine if the combination of paclitaxel and efatutazone (efatutazone dihydrochloride) improves the confirmed response rate in patients with advanced anaplastic thyroid cancer. SECONDARY OBJECTIVES: I. To estimate the overall survival (OS), duration of response, progression-free survival (PFS), and adverse event rates for the combination of paclitaxel and efatutazone. TERTIARY OBJECTIVES: I. The association of biomarkers with clinical outcome data will be assessed in an exploratory translational analysis. OUTLINE: Patients receive paclitaxel intravenously (IV) over 3 hours on day 1 and efatutazone dihydrochloride orally (PO) twice daily (BID) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up within 28 days, every 8 weeks until disease progression, and then every 6 months for 5 years.

MeasureTime frameDescription
Confirmed Response Rate (Partial Response [PR] or Complete Response [CR]) Per Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 CriteriaUp to 24 weeksThe response rate (percentage) is the percent of patients whose best response was Complete Response (CR) or Partial Response (PR) as defined by RECIST 1.1 criteria. Percentage of successes will be estimated by 100 times the number of successes divided by the total number of evaluable patients.

Recruitment details

Patients assigned to arm A will receive both paclitaxel and efatutazone; patients assigned to arm B will receive paclitaxel alone. However, please note that with update #2, arm B is closed and all patients should receive paclitaxel and efatutazone.

Time frame: Up to 24 weeks

Population: Patients who received efatutazone and paclitaxel combination were included in this analysis.

Duration of Confirmed Response

Duration of response is defined for all evaluable patients who have achieved a confirmed response as the date at which the patient's objective status is first noted to be a CR or PR to the earliest date progression (PD) is documented. The distribution of duration of response will be estimated using the method of Kaplan-Meier. (CR: Disappearance of all evidence of disease, PR: Regression of measurable disease and no new sites, PD: Any new lesion or increase by ≥50% of previously involved sites from nadir).

Time frame: The time from the first documented date of confirmed response (CR or PR) to date at which progression is first documented, assessed up to 5 years

Population: Only patients who achieved a confirmed response are included in this analysis.
