E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the objective response rate in subjects treated with ZD6474 (ZACTIMA™ ) 100 mg monotherapy |
|
E.2.2 | Secondary objectives of the trial |
To determine:
- the safety and tolerability of ZD6474 treatment in this patient population
- progression free survival (PFS) of hereditary MTC in subjects following ZD6474 100 mg therapy
- the disease control rate (DCR), duration of objective response (DOR) and duration of disease control with ZD6474
- whether treatment with ZD6474 results in a decrease of stool frequency in subjects with symptomatic diarrhea associated with hereditary MTC (“symptomatic response”)
To assess:
- the change in performance status (PS) from baseline of subjects given ZD6474 using World Heath Organization (WHO) PS
- the effect of ZD6474 100 mg dose on CTN and CEA levels
To characterise:
- the population pharmacokinetic (PK) of ZD6474 in subjects with hereditary MTC
- the pharmacokinetic-pharmacodynamic (PK-PD) relationship between ZD6474 exposure and changes in QTc prolongation, adverse events (AEs), response, PFS, and changes in calcitonin (CTN) and carcinoembryonic antigen (CEA) levels

E.3 | Principal inclusion criteria |
1. Provision of written informed consent
2. Female or male aged 18 years and over
3. Previously confirmed histological diagnosis of locally advanced or metastatic hereditary medullary thyroid carcinoma without standard therapeutic options for treatment. Documentation must be provided in the subject’s medical chart.
4. Life expectancy of 12 weeks or longer

6. One or more measurable lesions at least 10 mm in the longest diameter by spiral CT scan (5 mm slice thickness) or 20 mm with conventional techniques (>5 mm slice thickness) according to modified RECIST criteria
7. Negative pregnancy test for women of childbearing potential. Female subjects must be one year postmenopausal, surgically sterile, or using an acceptable method of contraception. Male subjects must be surgically sterile or using an acceptable method of contraception during their participation in this study
8. Able to swallow study medication as a whole tablet. Tablets should not be chewed, crushed or divided. |

E.4 | Principal exclusion criteria |

2. The last dose of prior chemotherapy is received less than 4 weeks before the start of study therapy
3. Radiation therapy within the last 4 weeks before the start of study therapy.
4. Major surgery within 4 weeks, or incompletely healed surgical incision before starting study therapy
5. Any unresolved toxicity greater than CTCAE grade 2 from previous anti-cancer therapy
6. Serum bilirubin greater than 1.5 x ULRR
7. Serum creatinine greater than 1.5 x ULRR or creatinine clearance ≤50 ml/min (calculated by Cockcroft-Gault formula)
8. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), or alkaline phosphatase (ALP) > 2.5 x ULRR if no demonstrable liver mets, or > 5 x ULRR if judged by the Investigator to be related to liver metastases
9. Significant cardiac event (eg. myocardial infarction, super vena cava [SVC] syndrome, New York Heart Association [NYHA] classification of heart disease ≥2 within 3 months before entry, or presence of cardiac disease that in the opinion of the Investigator increases the risk of ventricular arrhythmia
10. History of arrhythmia (multifocal premature ventricular contractions (PVC’s), bigeminy, trigeminy, ventricular tachycardia, symptomatic or uncontrolled atrial fibrillation) which is symptomatic or requires treatment (CTCAE grade 3) or asymptomatic sustained ventricular tachycardia. Subjects with atrial fibrillation controlled by medication are permitted.
11. Congenital long QT syndrome or 1st degree relative with unexplained sudden death under 40 years of age
12. QT prolongation with other medications that required discontinuation of that medication
13. Presence of left bundle branch block (LBBB)
14. QTc with Bazett’s correction unmeasurable or ≥ 480 msec or greater on screening ECG. (Note: If a subject has QTc ≥480 msec on screening ECG, the screen ECG may be repeated twice). One ECG, or the mean, if more than one are performed, must have a QTc value of <480 msec in order for the patient to be eligible for the study.
15. Potassium <4.0 mmol/L despite supplementation; serum calcium (or ionized or adjusted for albumin), or magnesium out of normal range despite supplementation
16. Pregnancy or breast feeding (women of child-bearing potential)
17. Any concomitant medications that may affect QTc or induce CYP3A4 function (with the exception of somatostatin or somatostatin analog) and / or prohibited medications referenced in Appendix E and Section 3.8 of the clinical study protocol
18. HTN not controlled by medical therapy (systolic blood pressure greater than 160 millimeter of mercury [mmHg] or diastolic blood pressure greater than 100 mmHg)
19. Previous or current malignancies at other sites within last 5 years, with the exception of in situ carcinoma of the cervix and adequately treated basal cell or squamous cell carcinoma of the skin
20. Evidence of severe or uncontrolled systemic disease or any concurrent condition which in the investigator’s opinion makes it undesirable for the patient to participate in the trial or which would jeopardize compliance with the protocol
21. Previous enrollment in the present study or previous enrollment on study with treatment using ZD6474
22. Involvement in the planning and conduct of the study (applies to both AstraZeneca staff or staff at the investigational site)
23. Receipt of any investigational agents within 30 days prior to starting study treatment
