简要总结
This randomized phase II trial studies the side effects and how well intensity-modulated radiation therapy (IMRT) and paclitaxel with or without pazopanib hydrochloride works in treating patients with anaplastic thyroid cancer. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as 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. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether radiation therapy and paclitaxel are more effective when given with pazopanib hydrochloride in treating thyroid cancer.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the safety of IMRT, paclitaxel, and pazopanib (pazopanib hydrochloride) suspension. (Run-in component) II. To evaluate and compare overall survival at 1 year from study registration. (Phase II component)
SECONDARY OBJECTIVES:
I. To evaluate local-regional control at 6 and 12 months. (Phase II component) II. To evaluate the rate of grade 4 (Common Terminology Criteria for Adverse Events version 4.0 [CTCAE, v. 4.0]) hemorrhage, grade 4 febrile neutropenia, or any grade 5 adverse event assessed to be definitely, probably, or possibly related to the induction or concurrent treatment components of the protocol regimen. (Phase II component) III. To evaluate the rates of other adverse events (CTCAE, v. 4.0) assessed to be definitely, probably, or possibly related to the induction or concurrent treatment components of the protocol regimen. (Phase II component) IV. To evaluate the rate of treatment discontinuation due to toxicity during the induction or concurrent treatment components of the protocol regimen. (Phase II component) V. To evaluate response (as per Response Evaluation Criteria in Solid Tumors [RECIST]) of the primary site following the treatment component in subjects with measurable disease prior to chemoradiation.

入选标准
- •Pathologically (histologically or cytologically) proven diagnosis of anaplastic thyroid cancer (a diagnosis that is noted to be "consistent with anaplastic thyroid cancer" with the presence of a thyroid mass is acceptable)
- •Note: Tissue collection for central review is mandatory, but central review is not required for eligibility; due to the aggressiveness of this disease, treatment will be started prior to central review
- •If there was a total or partial thyroidectomy completed within 3 months of enrollment, the surgical specimen must show the area of anaplastic thyroid cancer to be at least 1 cm in greatest dimension
- •The following minimum diagnostic workup is required:
- •History/physical examination within 2 weeks prior to registration
- •Imaging of neck and brain (computed tomography [CT] scan or magnetic resonance imaging [MRI]) and chest/abdominal imaging (chest x-ray or chest CT scan, or full body positron emission tomography [PET]/CT are acceptable) within 4 weeks prior to registration
- •Note: The CT scan of the neck must be done with contrast or if an MRI is done, with gadolinium; therefore, the CT portion of a full body PET/CT has to be a high resolution CT to be acceptable for eligibility
- •Abdominal imaging must cover the liver and adrenal glands; therefore, separate imaging is not required if these areas are covered by a chest CT scan

- •Documentation of the patient's history of corrected QT interval (QTc) prolongation, family history of prolonged QTc, and relevant cardiac disease within 10 days prior to registration
- •Evaluation of the patient's medications within 10 days prior to registration with attempt to change any medication that affects cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4)
- •Blood pressure =< 140/90 within 10 days of registration (must be taken and recorded by a health care professional); Note: if the systolic blood pressure is > 140 and/or diastolic blood pressure is > 90 at the time of registration, the patient's blood pressure must be controlled; systolic blood pressure must be < 140 and diastolic blood pressure must be < 90 on at least 2 separate measurements prior to the start of treatment, and the treating physician must believe that this is feasible in order to enroll the patient
- •Prothrombin time (PT)/international normalized ratio (INR)/partial thromboplastin time (PTT) within 1.2 x the upper limit of normal within 10 days prior to registration unless the patient is receiving coumadin and has a stable INR that is in range for the desired level of anticoagulation
- •Negative pregnancy test (serum or urine) within 10 days of registration in women of child-bearing potential
- •Women of childbearing potential and male participants who are sexually active must agree to practice adequate contraception during treatment and for 6 months post-treatment
- •The patient must provide study specific informed consent prior to study entry
排除标准

- •Known brain metastasis
- •Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy because of the potential for pharmacokinetic interactions with pazopanib; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
- •Certain medications that act through the cytochrome P450 (CYP450) system are specifically prohibited in patients receiving pazopanib and others should be avoided or administered with extreme caution
- •Strong inhibitors of CYP3A4 such as ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole may increase pazopanib concentrations and are prohibited; although, in exceptional circumstances, they may be administered in conjunction with lowering the dose of pazopanib by 50% of what would otherwise be administered; grapefruit juice is also an inhibitor of CYP450 and should not be taken with pazopanib
- •Strong inducers of CYP3A4, such as rifampin, may decrease pazopanib concentrations, are strictly prohibited

结局指标
主要结局
(Phase II) Overall Survival
时间窗: From randomization to last follow-up.Maximum follow-up for phase II participants at time of analysis was 4.2 years.
Overall survival time is defined as time from randomization to the date of death (failure) from any cause or last known follow-up (censored). Overall survival rates are estimated by the Kaplan-Meier method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. One-year rates are provided. Analysis occurred after all eligible participants were potentially followed for 3 years.
(Phase I) Number of Participants With Treatment-related Grade 4 Hemorrhage, Grade 4 Febrile Neutropenia, or Grade 5 Adverse Event (AE), or Discontinuation of Treatment Due to Toxicity [Adverse Events of Concern (AEC)]
时间窗: From registration to last follow-up. Maximum follow-up for run-in and phase II participants at time of analysis was 7.4 years.
Common Terminology Criteria for AEs (version 4.0) grades AE severity from 1=mild to 5=death. Discontinuation of treatment due to toxicity is defined as \< 75% of planned radiation therapy delivered. "Treatment-related" = definitely, probably, or possibly related to treatment. A single run-in arm was originally planned, but additional run-in arms were added due to amendments to the protocol regimen unrelated to toxicities. A two-stage design based on the binomial distribution was used in which the 1st stage analyzes the run-in arm and the 2nd stage analyzes run-in and phase II pazopanib arm participants combined. Because there were multiple run-in arms, only the last is used in the 2nd stage analysis. 1st stage: If ≤4 of 9 participants experience AEC, then conclude treatment is safe. 2nd stage: If ≤8 of 24 participants experience AEC, then conclude treatment safe. Otherwise conclude the treatment is too toxic. Summary data is provided here, see AE Module for specific AE data.
