Intensity-Modulated Radiation Therapy and Paclitaxel With or Without Pazopanib Hydrochloride in Treating Patients With Anaplastic Thyroid Cancer

A Randomized Phase II Study of Concurrent Intensity Modulated Radiation Therapy (IMRT), Paclitaxel and Pazopanib (NSC 737754)/Placebo, for the Treatment of Anaplastic Thyroid Cancer

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.

Study Overview

• Status: Completed
• Conditions: Thyroid Gland Anaplastic Carcinoma
• Intervention / Treatment: Drug: Pazopanib Hydrochloride; Drug: Paclitaxel; Radiation: Intensity-Modulated Radiation Therapy; Other: Placebo Administration

Detailed Description

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. (Phase II component)

OUTLINE:

RUN-IN COMPONENT: Patients receive paclitaxel intravenously (IV) over 1 hour once weekly and pazopanib hydrochloride orally (PO) once daily (QD) for 2-3 weeks. Patients then receive concurrent paclitaxel IV over 1 hour once weekly and pazopanib hydrochloride PO QD for 6-7 weeks (or until radiation treatment is completed) and intensity-modulated radiotherapy (IMRT) 5 days per week for 6.5 weeks (total of 66 Gy in 33 fractions). Beginning 25-31 days after the completion of IMRT, patients receive paclitaxel IV over 1 hour once weekly and pazopanib hydrochloride PO QD. Treatment repeats every 3 weeks for 4 cycles (for patients with no measurable disease) or continues in the absence of disease progression or unacceptable toxicity (for patients with measurable disease).

RANDOMIZED PHASE II COMPONENT: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive paclitaxel IV over 1 hour once weekly and pazopanib hydrochloride PO QD for 2-3 weeks. Patients then receive concurrent paclitaxel IV over 1 hour once weekly and pazopanib hydrochloride PO QD for 6-7 weeks (or until radiation treatment is completed) and IMRT 5 days per week for 6.5 weeks (total of 66 Gy in 33 fractions). Beginning 25-31 days after the completion of IMRT, patients receive paclitaxel IV over 1 hour once weekly and pazopanib hydrochloride PO QD. Treatment repeats every 3 weeks for 4 cycles (for patients with no measurable disease) or continues in the absence of disease progression or unacceptable toxicity (for patients with measurable disease).

ARM II: Patients receive paclitaxel IV over 1 hour once weekly and placebo PO QD for 2-3 weeks. Patients then receive concurrent paclitaxel IV over 1 hour once weekly and placebo PO QD for 6-7 weeks (or until radiation treatment is completed) and IMRT 5 days per week for 6.5 weeks (total of 66 Gy in 33 fractions). Beginning 25-31 days after the completion of IMRT, patients receive paclitaxel IV over 1 hour once weekly and placebo PO QD. Treatment repeats every 3 weeks for 4 cycles (for patients with no measurable disease) or continues in the absence of disease progression or unacceptable toxicity (for patients with measurable disease).

After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 1 year, and then annually thereafter.

Description

Inclusion Criteria:

• 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

• Spot urine protein to creatinine ratio (UPCR) < 1 or a 24-hour urine protein collection < 1 gm within 10 days prior to registration
• Creatinine < 1.5 mg/dL or within normal institutional limits within 10 days prior to registration; Note: if neither criteria is met, the creatinine clearance must be > 50 mL/min/1.73 m^2 per either the Cockcroft-Gault equation, Jeliffe method, or 12- or 24-hour urine collection
• Serum electrolytes including sodium, potassium, blood urea nitrogen (BUN), creatinine, glucose, magnesium, phosphate, and calcium within 10 days prior to registration
• 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

Exclusion Criteria:

• Known active invasive malignancy (except for non-melanomatous skin cancer or anaplastic thyroid cancer; the presence of prostate cancer confined to the prostate with a prostate-specific antigen [PSA] =< 1 ng/mL for more than 6 months also is allowed)

• Prior systemic chemotherapy for anaplastic thyroid cancer

  • Patients who have had chemotherapy or radiotherapy within 4 weeks of registration (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered > 4 weeks previously
  • Patients receiving other investigational agents
• Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields

• Patients with any of the following cardiovascular conditions within the past 6 months:

  • Cerebrovascular accident (CVA) or transient ischemic attack (TIA)
  • Admission for unstable angina
  • Myocardial Infarction
  • Cardiac angioplasty or stenting
  • Coronary artery bypass graft surgery
  • Pulmonary embolism, untreated deep venous thrombosis (DVT), or DVT which has been treated with therapeutic anticoagulation for less than 6 weeks
  • Arterial thrombosis
  • Symptomatic peripheral vascular disease
  • Class III or IV heart failure as defined by the New York Heart Association (NYHA) functional classification system; Note: a patient who has a history of class III heart failure and is asymptomatic on treatment may be considered eligible for the study
• Certain medications that are associated with a risk for QTc prolongation and/or torsades de pointes, although not prohibited, should be avoided or replaced with medications that do not carry these risks, if possible
• Patients who require heparin (other than low-molecular weight heparin)

• Patients with any condition that may impair the ability to absorb oral medications/investigational product including:

  • Prior surgical procedures affecting absorption including, but not limited to, major resection of stomach or small bowel
  • Active peptic ulcer disease
  • Malabsorption syndrome

• Patients with any condition that may increase the risk of gastrointestinal bleeding or gastrointestinal perforation, including:

  • Active peptic ulcer disease
  • Known intraluminal metastatic lesions
  • Inflammatory bowel disease (e.g., ulcerative colitis, Crohn's disease) or other gastrointestinal conditions which increase the risk of perforation
  • History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 28 days prior to beginning study treatment
• History of hemoptysis within 30 days of registration; Note: patients who have minimal bleeding from the mouth, which is clearly not related to a source in the lungs, i.e., surgery such as a non-lung biopsy, are eligible only after good hemostasis has been documented
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnancy or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception; this exclusion is necessary because the treatment involved in this study may be significantly teratogenic
• Prior allergic reaction to the study drug(s) involved in this protocol
• QTc prolongation defined as a QTc interval >= 480 msecs or other significant electrocardiogram (EKG) abnormalities are ineligible; Note: if unsure about EKG abnormality, the treating physician should discuss this with Drs. Sherman or Bible
• 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
  • Medications that have narrow therapeutic windows and are substrates of CYP3A4, cytochrome P450, family 2, subfamily D, polypeptide 6 (CYP2D6), or cytochrome P450, family 2, subfamily C, polypeptide 8 (CYP2C8) should be avoided and, if necessary, administered with caution

Beginning 25-31 days after the completion of IMRT, patients receive paclitaxel IV over 1 hour once weekly and pazopanib hydrochloride PO QD. Treatment repeats every 3 weeks for 4 cycles (for patients with no measurable disease) or continues in the absence of disease progression or unacceptable toxicity (for patients with measurable disease).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
(Phase II) Overall Survival	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.	From randomization to last follow-up.Maximum follow-up for phase II participants at time of analysis was 4.2 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)]	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.	From registration to last follow-up. Maximum follow-up for run-in and phase II participants at time of analysis was 7.4 years.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
(Phase II) Local-regional Control	Local-regional failure is defined as local-regional relapse/progression in the thyroid bed or regional lymph nodes. Time to local-regional failure is defined as time from randomization to the date of first local-regional recurrence, last known follow-up (censored), or death without local recurrence (competing risk). Failure rates are estimated using the cumulative incidence method. The protocol specifies 6- and 12-month estimates to be reported and for the full distributions of failure times to be compared between the arms. Analysis occurred after all eligible participants were potentially followed for 3 years.	From randomization to last follow-up.Maximum follow-up for phase II participants at time of analysis was 4.2 years. (Statistical analysis compares full distributions therefore all available follow-up was used.)
(Phase II) Percentage of Participants With Treatment-related Grade 4 Hemorrhage, Grade 4 Febrile Neutropenia, or Grade 5 Adverse Event, or Discontinuation of Treatment Due to Toxicity [Adverse Events of Concern]	Common Terminology Criteria for Adverse Events (CTCAE, v. 4.0) grades adverse event severity from 1=mild to 5=death. Discontinuation of treatment due to toxicity is defined as < 75% of planned radiation therapy delivered. Adverse events rated as definitely, probably, or possibly related to treatment were considered treatment-related. Summary data is provided in this outcome measure.; See Adverse Events Module for specific adverse event data.	From start of treatment to last follow-up.Maximum follow-up for phase II participants at time of analysis was 4.2 years.
(Phase II) Percentage of Participants With Treatment-related Grade 3 or 4 Adverse Events Other Than Grade 4 Hemorrhage or Grade 4 Febrile Neutropenia [Not Adverse Events of Concern]	Common Terminology Criteria for Adverse Events (CTCAE, v. 4.0) grades adverse event severity from 1=mild to 5=death. Adverse events rated as definitely, probably, or possibly related to treatment were considered treatment-related. Summary data is provided in this outcome measure.; See Adverse Events Module for specific adverse event data.	From start of treatment to last follow-up.Maximum follow-up for phase II participants at time of analysis was 4.2 years.
(Phase II) Percentage of Participants With Complete or Partial Response of the Primary Site After Chemoradiation Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1	Complete Response: Disappearance of all target lesions; Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.	2-4 weeks after treatment (approximately week 10-14)
