Thyroid Cancer and Sunitinib
Palabras clave

Descripción
The THYSU trial is a phase II trial of sunitinib (Sutent) in patients with locally advanced or metastatic anaplastic, differentiated or medullary thyroid carcinoma.
Due to arguments showing that angiogenesis could be involved in progression of metastatic thyroid carcinoma and to objective response during a phase I trial with sunitinib, it was justified to evaluate in a prospective trial the efficacy of sunitinib in metastatic thyroid carcinoma. Furthermore, the standard treatment of metastatic thyroid carcinoma when a general treatment is to be prescribed is limited to radioiodine. When radioiodine becomes ineffective, there is no standard treatment despite some usage of chemotherapy.
The objective of the trial is to determine the objective tumor response rate in patients with locally advanced or metastatic anaplastic, differentiated or medullary thyroid carcinoma treated with sunitinib, a secondary objective is to evaluate the safety of sunitinib in these patients with thyroid carcinoma.
The treatment of sunitinib is the standard dosage and schedule. Sunitinib is given orally at the dose of 50 mg daily for 28 days followed by 2 weeks of rest. Forthcoming cycles remain identical. Modification of the dose may use a lower dose at 37.5 mg or 25 mg given daily on the same schedule. All patients will receive repeated cycles of treatment until disease progression, occurrence of unacceptable toxicity, withdrawal of patient consent, or other withdrawal criteria are met. After discontinuation of treatment and the mandated 28-day follow up, patients will be followed only in order to collect information on further antineoplastic therapy and survival. In patients discontinuing treatment for reasons other than disease progression, tumor assessment will continue until disease progression, or initiation of other antineoplastic therapies.
The more frequent side effects are asthenia, mucositis, arterial hypertension, hand foot syndrome and diarrhea. Other side effects have been reported including nausea, vomiting, cutaneous events, decrease in left ventricular ejection fraction, neutropenia, and thrombopenia.
The patients must meet all of the following inclusion criteria to be eligible for enrollment into the trial:
- Patients must sign and date IRB/EC-approved informed consent.
- Age ≥ 18.
- Patients must have a life expectancy of at least 3 months and Karnofsky performance status ≥ 70%
- Patients must have histologically confirmed TC
- Tumor disease must be progressive (evidence of disease progression within 6 months)
- Patients should not be candidates for surgical resection, external beam radiotherapy or radioiodine, and patients must not have more than one previous systemic treatment for cancer
- Patients must have measurable disease defined by RECIST criteria as at least one lesion at least 2 cm in length by conventional CT techniques or at least 1 cm by spiral CT scan.
- Resolution of all acute toxic effects of any prior treatment to NCI - CTCAE (version 3.0) grade < 1.
- Patients must have discontinued from radiation therapy at least 4 weeks before first dose of study treatment and must have recovered from any toxic effects of treatment.
- Blood pressure < 140 / 90 mmHg
- Patients must have adequate organ function.
- Patients with reproductive potential must use medically acceptable contraceptive method.
- Willingness and ability to comply with the study procedures.
- Patient affiliated with or profiting from a social security system
The presence of any non-inclusion criteria will exclude a patient from study enrollment.
Prior to undergoing any specific study procedures, patient and investigator sign informed consent. During the initial visit including verification of eligibility criteria, an interview with the patient is conducted regarding his/her recent and past clinical and treatment history (including oncology history). Physical examination including examination of major body systems, Karnofsky performance status, body weight, height, and vital signs is performed. Laboratory data are collected (hematology and chemistry, coagulation, thyroid tests, tumor markers and pregnancy test if applicable). Para clinic evaluations (12-lead ECGs and tumor imaging) are carried out. LVEF assessed by Echocardiogram or by MUGA scan (if necessary) and Brain Naturatic Peptide (Or NT pro-BNP) test are done.
During the follow-up, the patients are followed between the end of week 4 and week 6 by clinical and biological evaluation. Evaluation of tumor sites under sunitinib is planned every 2 cycles with CT scans. For patients with anaplastic or differentiated thyroid carcinoma, the first stage will include 21 efficacy-evaluable patients. An additional 29 efficacy-evaluable patients will be included at the second stage.
For patients with medullary thyroid carcinoma, the first stage will include 11 efficacy-evaluable patients. An additional 7 to 14 efficacy-evaluable patients will be included at the second stage.
10 French Oncology Departments are involved in this trial.
