Enrollment: 37 participants; Allocation: NA; Intervention model: SINGLE_GROUP

Brief summary:
This study will examine the effectiveness of an investigational drug called ZD6474 (also known as vandetanib or ZACTIMA). Vandetanib is an experimental drug that is designed to prevent the growth and development of new blood vessels on tumors and to prevent the direct growth of cancer cells. It has been tested in a number of clinical trials on adults with cancer, but the United States (U.S.) Food and Drug Administration has not specifically approved it as a cancer treatment. The purpose of this investigational study is to better understand how vandetanib affects humans who have kidney cancer related to von Hippel-Lindau (VHL) disease, and to develop tests that may improve researchers understanding of kidney cancer and its effects.

Volunteers must be at least 18 years old and must have been diagnosed with kidney cancer related to VHL. Candidates must have a life expectancy greater than three months and must have at least one measurable renal tumor for study purposes. Candidates may not be receiving any other investigational agents or have been treated with an investigational drug within the past four weeks. Candidates who have had surgery, chemotherapy, or radiotherapy within the past four weeks will be excluded from the study. Candidates will be screened with a physical examination and medical history.

During the study, participants will receive an oral dose of vandetanib once a day for 28 days (a treatment period known as a cycle). Participants will need to return to the National Institutes of Health every two weeks on the same day of the week as the first dose of vandetanib for a series of tests and procedures, including blood and urine tests and an electrocardiogram. Every 12 weeks, computerized tomography (CT) or magnetic resonance imaging (MRI) scans will be done to assess the size of participants tumors. Participants whose tumors do not grow and who do not have unacceptable side effects may continue to receive vandetanib to maintain the current condition, until researchers conclude the study....

Detailed description:
Background:

Von Hippel Lindau disease is a hereditary cancer syndrome in which affected individuals are at risk for developing tumors in a number of organs, including the kidneys, brain, spine, adrenal glands, eyes and pancreas.

The molecular hallmark of VHL is inactivation of the VHL gene which leads to accumulation of proteins targeted for degradation through the ubiquitin pathway, which includes a group of transcriptionally active proteins called the hypoxia inducible factors (HIF), whose alpha subunits undergo degradation in a VHL-dependent fashion. Accumulation of HIFs results in overexpression of several genes including vascular endothelial growth factor (VEGF), glucose transporter 1 (GLUT-1), transforming growth factor (TGF)-alpha, platelet- derived growth factor (PDGF), and erythropoietin, which are believed to play a role in tumorigenesis, tumor progression and metastasis.

ZD6474 is an orally administered receptor tyrosine kinase inhibitor with activity against the Kinase insert domain-containing receptor/vascular endothelial growth factor receptor 2 (KDR/VEGFR2) and the epidermal growth factor receptor (EGFR). Kinase insert domain receptor (KDR)/vascular growth factor receptor 2 (VEGFR2) is an endothelial cell receptor for vascular endothelial growth factor (VEGF) and plays a crucial role in mediating tumor angiogenesis, while epidermal growth factor receptor (EGFR) (a receptor for TGF-alpha and epidermal growth factor (EGF) is believed to mediate tumor growth and proliferation.

Objective:

Primary Objective

To assess the overall response rate in VHL patients with renal tumors treated with single agent ZD6474

Secondary Objectives:

To study the safety and tolerability of ZD6474

To evaluate time to progression and progression-free survival in VHL patients receiving ZD6474

To study the effect of ZD6474 treatment on non-renal tumors associated with von Hippel Lindau disease ( pancreatic tumors, pheochromocytoma, central nervous system (CNS) hemangioblastomas)

To investigate the effect of ZD6474 on circulating endothelial cells and endothelial progenitor cells and to explore the utility of these markers as surrogates of angiogenesis inhibition

To investigate the effect of ZD6474 on biomarkers of angiogenesis such as plasma VEGF and soluble VEGFR2

Eligibility:

Adults with clinical diagnosis of von Hippel Lindau disease

Presence of one or more measurable renal tumors

Age greater than or equal to 18 years

Adequate organ function, performance status (Eastern Cooperative Oncology Group (ECOG) 0-2) and life expectancy (greater than 3 months)

Design:

Single agent ZD6474 administered daily at a starting dose of 300mg per day

Patients will be evaluated for response every 12 weeks using Response Evaluation Criteria in Solid Tumors (RECIST) criteria

The study is based on an open label two-stage optimal phase II design

Accrual of a maximum of 37 patients.

Arms: arm 1: 300 mg/day (starting dose) oral dose of vandetanib once a day for 28 days

INTRODUCTION 
 
1.1 
STUDY OBJECTIVES 
  
1.1.1 Primary Objective 
• To assess the overall response rate in VHL patients with renal tumors treated with single agent 
ZD6474  
 
1.1.2 Secondary Objectives:  
• To study the safety and tolerability of ZD6474 
• To evaluate time to progression and progression-free survival in VHL patients receiving 
ZD6474 
• To study the effect of ZD6474 treatment on non-renal tumors associated with von Hippel 
Lindau disease (pancreatic tumors, pheochromocytoma, CNS hemangioblastomas) 
• To investigate the effect of ZD6474 on circulating endothelial cells and endothelial progenitor 
cells and to explore the utility of these markers as surrogates of angiogenesis inhibition 
• To investigate the effect of ZD6474 on biomarkers of angiogenesis such as plasma VEGF and 
soluble VEGFR2 
 
1.2 
BACKGROUND AND RATIONALE 
1.2.1 von Hippel Lindau Disease 
Von Hippel Lindau disease is a hereditary cancer syndrome transmitted in an autosomal 
dominant fashion. The underlying defect is a germline mutation in the VHL gene, which places 
affected individuals at risk for developing tumors in a number of organs, including the brain, 
spine, kidneys, adrenal glands, eyes and pancreas (1-6).   The incidence of VHL is approximately 
one in 36,000 live births (1,7).  
 
1.2.2 VHL Clinical Manifestations 
Bilateral, multifocal clear cell renal carcinoma 
CNS Hemangioblastomas (Cerebellum, Spine) 
Pancreatic neuroendocrine tumor and cysts 
Pheochromocytomas 
Retinal angiomas 
Endolymphatic sac tumors 
 
Renal Tumors in VHL 
 
Affected individuals in VHL kindreds are at risk for the development of bilateral, multifocal 
clear cell renal carcinoma (1-5).

While these tumors can present as localized tumors, they can grow and metastasize.  Historically, 
35-45% of VHL patients died of metastatic renal cell carcinoma.

Pancreatic neuroendocrine tumor 
      VHL pancreatic cysts 
 
The pancreatic neuroendocrine tumors are malignant and can metastasize.

3) These patients are also at risk for the development of pheochromocytomas which can 
occur at an early age (18). 
 
      
 
 
Abdominal CT scan (left) and MRI scan (right) reveal the presence of bilateral pheochromocytomas in a 10 year old boy. 
 
VHL pheochromocytomas can occur at adrenal or extra-adrenal sites and, although the 
pheochromocytomas are usually benign, they can be can be lethal.  They can also be 
malignant and can metastasize.

VHL associated pheochromocytomas can be extra-adrenal.  Panel A shows a pulmonary 
pheochromocytoma in a VHL patient.  These tumors can also be malignant.  Panel B shows 
a large retroperitoneal, recurrent malignant pheochromocytoma that had spread to the 
lungs (Panel C) in a 24 year old female.                      
 
1.2.3 The VHL Tumor Suppressor Gene 
By studying VHL kindreds here at the NCI we were able to identify the VHL gene (19).  The 
gene is located on the short arm of chromosome 3 (3p25-26). VHL is a classical tumor 
suppressor gene and tumorigenesis due to VHL inactivation conforms to Knudson’s ‘two-hit’ 
hypothesis (20). The gene has three exons that encode the VHL protein (19). Two isoforms of 
the VHL protein have been described. Full length VHL protein has 213 amino acids and 
localizes to the nucleus as well as the cytoplasm. A truncated form, resulting from translation 
initiation at codon 54, has also been characterized and appears to be functionally acive (21,22).

Genetic linkage analysis at the NCI resulted in the identification of the G7 VHL cDNA, which turned out to be the VHL gene.  
 
We and others have shown that this gene is also the gene for the common form of sporadic renal 
cell carcinoma (viz., clear cell RCC).  
 
VHL germline mutation spectrum 
 
VHL mutations: Functional and Biologic consequences 
While VHL mutations were initially identified as the genetic basis of von Hippel Lindau disease, 
inactivation of the gene by mutation or promoter hypermethylation has also been described in a 
high proportion of sporadic clear cell renal cancers. VHL protein forms a complex with other 
cellular proteins including elongins B and C, and Cullin 2 (the VCB-CUL2 complex) (23). This 
complex plays an important role in the degradation of cellular proteins via the ubiquitin pathway. 
Inactivation of VHL consequently leads to accumulation of proteins targeted for degradation 
through this pathway. This includes a group of transcriptionally active proteins called the

hypoxia inducible factors (HIF), whose alpha subunits undergo degradation in a VHL-dependent 
fashion (24). Accumulation of HIFs results in overexpression several genes including VEGF, 
GLUT-1, TGF-, PDGF, and erythropoietin (1-4). VEGF is an important regulator of tumor 
angiogenesis and hence is implicated in tumor growth and progression. VEGF exerts its activity 
through several receptor tyrosine kinases expressed on endothelial cells, chief among them being 
the fms-like tyrosine kinase-1/VEGF receptor 1 (Flt-1/VEGFR1) and the kinase insert domain 
containing receptor/VEGF receptor 2 (KDR/VEGFR2) (25). In addition to promoting 
angiogenesis in the tumor microenvironment, VHL inactivation can also directly promote tumor 
growth via the autocrine and paracrine effects of TGF-, and PDGF, which act through receptor 
tyrosine kinases such as the epidermal growth factor receptor (EGFR, a ligand for TGF-a) 
expressed on tumor cell surface. Thus VHL inactivation initiates a series of downstream events 
that promote tumor progression.  
   
        VHL gene pathway 
 
1.2.4 Treatment for VHL-associated tumors 
Although a variety of systemic treatment options including cytokines (IL-2, IFN) as well as 
newer targeted anti-angiogenic agents (e.g. sunitinib, sorafenib) are available for patients with 
sporadic metastatic clear cell RCC, these agents have not been evaluated in the management of 
VHL associated RCC. Consequently, the treatment approach for VHL associated renal tumors 
remains surgical and involves resection of tumors that have reached a size of approximately 3 
cm.   
 
We have estimated that affected VHL individuals may develop up to 600 tumors per kidney (26).  
Over the past 15 years we have observed patients with VHL-associated renal cancer until their 
tumors grew to 3 cm in diameter, whereupon nephron-sparing surgery is recommended.  This 
strategy is used to increase time between operations and decrease patient morbidity.  With this 
treatment approach, we have followed 96 von Hippel-Lindau (VHL) patients for a median of 60 
months.  No patient with maximum renal tumor diameter less than 3 cm has developed 
metastases (27,28).  Tumor diameters greater than 3 cm are associated with increasing frequency 
of metastases. There is no effective standard therapy for VHL patients with metastatic renal 
cancer. Historically 35-45% of patients affected with VHL have died of metastatic renal 
carcinoma. Currently, tumors of non-renal origin are similarly managed by surgical resection to 
relieve symptoms or circumvent potentially dangerous sequelae (29,30) (for e.g. CNS 
hemangioblastomas, pheochromocytomas) or diminish metastatic potential (31) (e.g. pancreatic 
neuroendocrine tumors).

1.2.5 ZD6474 
ZD6474 is an orally administered receptor tyrosine kinase inhibitor with potent activity against 
VEGFR2 as well as activity against EGFR (32,33). 
 
Murine preclinical human xenograft models have demonstrated activity of ZD6474 against a 
variety of tumors including those arising in the lung, prostate, ovary, breast and colon. Reduction 
in tumor blood flow, vascular density and vascular permeability have been seen in a mouse 
xenograft model, suggesting inhibition of the VEGF pathway by the drug (34). The following is 
a summary of pre-clinical and clinical studies with ZD6474: 
 
In vitro studies (34) 
In isolated enzyme assays, ZD6474 was found to be a potent inhibitor of KDR tyrosine kinase 
activity (IC50=40nM), with additional activity against Flt-4 (IC50=110nM) and EGFR (IC50= 
500nM. Less potent activity was seen against a range of other tyrosine kinases including 
PDGFR, Tie-2, FGFR1, MEK, CDK2, c-kit, ErbB2, FAK, PDK-1, AKT and IGF-1R, with IC50 
ranging from 1M to >200M.  
 
ZD6474 inhibited the proliferation of both VEGF-stimulated and EGF-stimulated HUVEC cell 
lines (IC50=60nM and 170nM, respectively), while basal HUVEC proliferation was not 
significantly affected. When co-cultured with human fibroblasts, endothelial tube formation by 
HUVEC cells was inhibited at similar concentrations of ZD6474. Direct inhibition of tumor 
growth was demonstrated against established lung, colon, ovarian, breast, and prostate cancer cell 
lines, but only at higher concentrations, with IC50s in the 0.6 to 13.5 M range. 
 
The effect of ZD6474 on cardiovascular function has been investigated in vitro using the human 
ether-a-go-go gene assay as well as by assessment of action potential parameters recorded from 
canine Purkinje fibres. A concentration dependent increase in action potential duration was seen 
in these assays. 
 
The parent compound as well as the N-oxide and N-desmethyl metabolites were active in the 
above assays. 
 
Pre-clinical studies 
Pharmacokinetic Studies and metabolism 
Pharmacokinetic studies were performed in rats and dogs. In both species, >50% of the drug was 
absorbed when administered orally. Time to peak plasma concentration was 3-8 hours. Plasma 
clearance was rapid and was greater in male than in female rats. The drug was rapidly and 
extensively distributed with apparent volumes of distribution of approximately 30L/kg in both 
male and female rats. The highest concentrations were found in the GI tract, liver, adrenal glands, 
Harderian glands, pituitary, spleen and pigmented tissue. Delayed clearance from adrenal, kidney 
and testes was observed. The terminal half life was estimated at 16b hours in male and 31 hours in 
female rats, and at 8.27 hours in dogs.The drug is eliminated both by biliary excretion and in 
urine. Two metabolites have been identified in samples from rats and dogs- the N-oxide of 
ZD6474 and the N-desmethyl of ZD6474.

ZD6474 underwent minimal metabolism in rat and dog hepatocytes and no metabolism in human 
hepatocytes or human microsomes. No inhibitory effects on the activity of human P450 
isoenzymes CYP1A2, 2C9, 2C19 or 3A4 were observed but the drug inhibited activity of CY 
2D6. 
 
Plasma protein binding ranged from 83% in the rat to 90% in human. ZD6474 was found to bind 
both human serum albumin and alpha-1-glycoprotein. 
 
Toxicology 
Single oral doses of 2000mg/kg in mice and rats were not tolerated. A single oral dose of 
1000mg/kg was tolerated in rats and produced premature death in 1/10 mice. A single IV dose of 
50mg/kg induced early death in 1/10 mice. The following organ-specific toxicities were seen in 
multiple-dose studies: 
 
o Dose-related dysplasia of the epiphyseal growth plates of the femoro-tibial joint was seen in 
rats receiving 25-75mg/kg/day and in dogs dosed at 40mg/kg/day by one month.  
o Elevated ALT, AST and LDH as well as histopathologic changes consistent with 
hepatocellular necrosis and acute cholangitis were seen in the one-month rat study at a dose 
of 75mg/kg/day. Death from acute cholangitis was seen in rats receiving 20mg/kg/day in the 
6-month study. These changes were not observed with the one-month or nine-month dog 
studies. 
o Gastro-intestinal toxicity in the form of emesis, diarrhea and weight loss was observed in the 
1 and 9-month dog studies. No accompanying histopathologic changes were noted, and the 
toxicity was reversible on cessation of drug use. 
o Renal papillary necrosis was seen in the rat 1-month study at doses of 25-75mg/kg/day 
o Decreased numbers of corpora lutea, increased post-implantation loss, embryofetal loss, 
delayed fetal development, heart vessel abnormalities, and precocious ossification of skull 
bones reflect the range of reproductive and embryofetal toxicity observed in rats 
o Reversible histopathologic and ultrastructural changes consistent with phospholipidosis was 
seen in the rat 1-month and 6-month studies, but were not observed in the dog studies 
o Reversible, dose-related acute folliculitis and epidermal microabscess formation in the 
muzzle region of skin was noted in both the 1-month and 6-month rat toxicity studies 
o In dog studies, following single oral doses of 5, 15, or 40mg/kg, an increase in hart rate 75-
360 minutes following the largest dose was observed. In the dose range studies, no clear 
effects on blood pressure, PR interval, QRS duration, RR interval, QT interval, waveform or 
rhythm were seen 
 
Biologic Effects and efficacy against tumors 
 
The following effects consistent with VEGF inhibition were seen in animal studies: 
 
o When administered at a dose of 50mg/kg to Alderley Park rats, ZD6474 inhibited the 
hypotension normally induced by administration of bolus VEGF 
o Dose-dependent increases in the hypertrophic chondrocyte zone of the epiphyseal growth 
plates of growing rats were seen

o ZD6474 inhibited tumor-associated angiogenesis in athymic mice intradermally implanted 
with A549 lung cancer cells 
o ZD6474 inhibits tumor vascular flow, volume and permeability as assessed by K trans 
measurements in established PC-3 prostate tumor xenografts using dynamic contrast-
enhanced MRI 
o Antitumor activity 
 In human tumor xenograft models (lung, prostate, ovary, breast, vulval, colon),  ZD6474 
inhibited the growth of established subcutaneous tumors in mice 
 Tumor regression was observed in established PC-3 prostate tumor xenografts, but not in 
a Calu-6 (lung) tumor xenograft model 
 In murine spontaneously metastatic tumor models (melanoma and renal cell cancer) 
administration of ZD6474 reduced both primary tumor growth and the incidence of 
pulmonary metastases 
 Anti-tumor effects of ZD6474 were also identified in a human colon tumor xenograft in 
athymic rats and in two syngeneic tumor models (melanoma, lung) in immunocompetent 
mice 
 Inhibition of angiogenesis as evidenced by changes in microvascular architecture was 
seen in a murine orthotopically implanted renal cell cancer model (35). 
 
Human Studies (34, 36) 
 
Phase I Studies: 
Several phase I trials have been conducted in human subjects. Trial 6474IL/0001 (Western 
study) was conducted as a multicenter, dose escalation phase I trial evaluating 50, 100, 200, 300, 
500 and 600mg doses administered orally as a daily single dose. A total of 77 patients have been 
treated on this trial at various dose levels, including an expanded cohort of 19 and 25 patients 
respectively at the 100mg and 300mg dose levels who were enrolled to better evaluate the effect 
of ZD6474 on QT interval and ST, T wave changes. A second phase I trial conducted in Japan 
(TVE-15-11) followed a dose escalation pattern evaluating 100, 200, 300 and 400mg daily oral 
doses. A total of 18 patients have been accrued on this trial.  
 
Pharmacokinetics 
Pharmacokinetic data obtained from the Western and Japanese studies were comparable. 
Absorption was highly variable, with individual patients having a Tmax as late as 24 hours post-
dose.  Following achievement of maximum plasma concentration, Cmax declined in a biphasic 
manner. Terminal half-life was estimated to be about 4-5 days and appeared to be independent of 
dose. Both mean AUC and Cmax increased with increasing dose in a linear manner with about 2 
to 6 fold in inter-individual variability in AUC for a given dose. A comparison of the mean 
weekly trough levels suggest that steady state was achieved by day 29, with marked 
accumulation between day 1 and 29.  
 
Adverse Events 
The most common adverse events seen on both trials were: 
1) Rash- At least 2 distinct types of rash were seen- A macular erythema and a follicular 
(acneiform) rash. Rash was reported in 54 (72%) patients in the Western and 14 (77.8%) patients 
in the Japanese study. The occurrence of rash appeared to be dose-dependent.

2) Gastrointestinal toxicity- Diarrhea was reported in 42 (56%) of the Western patients and 10 
(56%) of the Japanese patients. Other common GI side effects seen the western and Japanese 
studies included nausea (39% in the Western and 22% in the Japanese studies), vomiting (22% 
and 17% respectively), anorexia (29% and 28% respectively) and constipation (24% in the 
Western study). 
3) Central Nervous System- Headaches were reported by 19 (25%) patients and dizziness by 14 
(17%) patients in the Western study. 27% of the patients in the Japanese study reported 
headaches. 
4) Cardiovascular toxicity-

In the western trial, 6 patients (8%) had T-wave or ST-segment changes consistent with 
repolarization abnormalities. 
b. 
QT/QTc prolongation- In the Western study, in the initial 49 patients enrolled, QTc 
prolongation occurred in 0 of 9 patients at 50mg, 1 of 8 patients at 100mg, 2 of 8 patients at 
200mg, 1 of 8 patients at 300mg, 2 of 8 patients at 500mg, and 1 of 8 patients at 600mg. The 
protocol was subsequently amended to include 11 additional patients at the 100mg dose level and 
12 patients at the 300mg dose level, along with the use of extensive ECG monitoring to assess 
QTc prolongation. In the expanded cohorts, 1/11 patients at the 100mg dose level and 2/12 
patients at the 300mg dose level had QTc prolongation. In the Japanese study, 11/18 patients 
(61%) developed QTc prolongation. A PK-PD correlation for QTc prolongation appears to exist. 
The relationship is best described by a direct linear effect model with a concentration of 1ng/ml 
causing an increase of 0.0243 ms in QTc interval. None of the QTc prolongations were 
considered to symptomatic 
c. Hypertension- Hypertension was seen in 21% of the patients in the two trials and on average 
involved a 5mm Hg increase in mean arterial pressure.  
 
Other commonly occurring adverse events (occurring in >10%) include: Fatigue (36%), 
abdominal pain (35%), back pain (15%), fever (14%), cough (14%), peripheral edema (12%), 
insomnia (12%), hematuria (11%), dyspnea (11%), proteinuria (11%).  
 
Dose limiting toxicity 
In Trial 6474IL/0001, dose levels of 50, 100, 200, 300, 500 and 600 mg/day were evaluated.  At 
600 mg/day, 3 of 8 patients developed dose limiting toxicity (DLT): thrombocytopenia, and 
diarrhea.  Because the plasma levels of ZD6474 observed in subjects in the 500 mg overlapped 
considerably with those at 600 mg, it was concluded that doses to take forward into later phases 
of development were less than 500 mg. 
 
In Trial TVE-15-11, dose levels of 100, 200, 300 and 400 mg/day were evaluated.  DLT was seen 
in 2 of 3 subjects in the 400 mg/day cohort (increased alanine aminotransferase and hypertension) 
and 2 of 6 subjects in 300 mg/day cohort (grade 3 diarrhea, hypertension, and headache in one 
patient, and grade 2 rash lasting longer than 7 days in a second subject). 
 
Therefore, in both trials a dose of 300 mg/day was identified as the highest well-tolerated dose of 
ZD6474. 
 
Withdrawal from Study 
67 patients were withdrawn from study in the 6474IL/0001 trial. 56 of these withdrawals were a

result of disease progression. 6 patients were withdrawn from study due to adverse events. One 
patient was withdrawn because of a rash, one patient due to fatigue, one due to folliculitis, and 
one patient was withdrawn on account of abdominal pain. A 72 year old female with colorectal 
cancer and pre-existing hypertension and edema developed congestive heart failure and was 
withdrawn from study as a consequence. The etiology of the heart failure is unclear and a 
contribution from ZD6474 cannot be ruled out. One patient was withdrawn from protocol due to 
abnormal QTc prolongation. 3 patients withdrew consent and were taken off study consequently. 
 
In the Japanese study, 5/18 patients were withdrawn from study due to disease progression. In 
addition, one patient with QTc prolongation and one with dose limiting alanine aminotransferase 
elevation were withdrawn. 
 
Efficacy 
Phase I study results 
Two phase I studies have been completed in the West and Japan (6474IL/0001 and 6474JP/0001), 
in which 90 (72 Western and 18 Japanese) patients with malignant tumors have been exposed to 
ZD6474 (50 to 600 mg).  By the end of July 2002, safety data were available from 70 patients (40 
males and 30 females).  Cohorts received doses ranging from 50 mg/day to 600 mg/day in the 
Western phase I study and from 15 patients receiving doses ranging from 100 mg/day to 400 
mg/day (9 males and 6 females) in the Japanese trial. In the Japanese Phase I trial, nine patients 
with non-small cell lung cancer (NSCLC) who were heavily pre-treated and failed all prior 
therapy regimens (seven adenocarcinomas, one squamous cell, and one carcinoma not otherwise 
specified) were treated with ZD6474; four achieved partial response at doses ranging from 200 to 
300 mg.  This suggests that ZD6474 may have activity as monotherapy in otherwise 
chemoresistant NSCLC.  Testing this agent in other tumors in light of these results is appropriate.   
 
Summary  
The data from the Phase I studies confirm that ZD6474 is safe for further study in patients with 
cancer.  Dose limiting toxicity in greater than 33% of patients was observed at doses above 300 
mg in both the Western and Japanese Phase I trials.  Plasma concentrations of ZD6474 achieved 
at steady state with 300 mg cover the theoretical IC50 and KDR as extrapolated from in vitro data 
in the VEGF-stimulated umbilical vein endothelial cells in 100% of patients. A dose of 300 mg, 
with options for stepwise dose reductions to ensure tolerability, is therefore recommended.  The 
clinical effect of ZD6474 was shown in preliminary results from the Phase I study in Japan, in 
four of nine patients with NSCLC who received up to 300 mg of ZD6474 had objective responses 
as evaluated by radiographic studies.  
 
 
Phase II Studies: 
Several phase II studies are either currently in progress or have been completed.   
 
Two Phase II studies in NSCLC with ZD6474 have been completed.  A randomized double blind 
Phase II trial comparing ZD6474 monotherapy with gefitinib monotherapy in 168 patients with 
advanced NSCLC as second or third line therapy demonstrated that patients receiving ZD6474 
300mg had a statistically significant prolongation of progression free survival (PFS) compared 
with gefitinib 250mg, with a mean PFS of 11.0 weeks and 8.1 weeks respectively.  The adverse 
event profile of ZD6474 was similar to that seen in previous trials, and included diarrhea (CTC

grade 3/4, 8.4%), rash (CTC grade 3/4, 4.8%) and asymptomatic QTc prolongation (all CTC 
grade 1, 20.5%). A higher incidence of cardiac, gastrointestinal and respiratory serious adverse 
events was noted in the ZD6474 arm compared with the gefitinib arm, although it is unclear if 
this increase can be attributed to ZD6474 (37) 
 
Another randomized double blind Phase II study evaluated PFS in second-line treatment of 127 
patients with advanced NSCLC, and demonstrated that ZD6474 100mg or 300mg plus docetaxel 
increased median PFS to 19 weeks and 17 weeks respectively, compared with 12.0 weeks for 
docetaxel plus placebo (38). While toxicities were similar to those expected in patients treated 
with docetaxel and those observed in other ZD6474 studies, the ZD6474 arm had more serious 
adverse events compared to the docetaxel/placebo arm.  
 
In an ongoing randomized double-blind phase IIa dose-finding study in 53 Japanese patients with 
NSCLC were given ZD6474 as monotherapy, at doses of 100, 200 or 300 mg/day.  Interim 
results demonstrated a 11% PR rate and a 51% disease control rate (PR+CR+stable disease) (39). 
The toxicity profile was similar to that seen in other trials with ZD6474, although the 
investigators reported a death related to interstitial lung disease that was considered to be related 
to ZD6474. Also reported was a case of cerebellar hemoorhage in a patient receiving the 200mg 
dose. 
 
Results from a phase II trial to assess objective tumor response in patients with hereditary 
metastatic medullary thyroid cancer having mutations in the RET protooncogene receiving 
ZD6474 monotherapy (300mg/day) were recently reported (40). Three of sixteen patients 
enrolled had a partial response, while an additional ten patients demonstrated stable disease >8 
weeks. A >50% reduction in serum tumor markers (calcitonin) was observed in 12 patients. 
Based on these promising data, a randomized phase II study of ZD6474 vs placebo in patients 
with advanced medullary thyroid cancer is currently being planned. 
 
Emerging Safety Profile/ Composite List of Adverse Events 
Notable and/or frequent side effects associated with the above phase I and phase II studies have 
been described along with each study. The following is a system-wise list of adverse events 
encountered on all completed or currently accruing studies as summarized in the most current 
Investigators’ Brochure (version 9) provide by the drug sponsor. 
 
Reported adverse events that may be related to vandetanib are listed below by body system. 
 
• Cardiovascular 
−Abnormal ECG (with or without QT prolongation; ie, either T-wave or 
ST-segment changes consistent with repolarization abnormalities), torsade-de-pointes, 
ventricular tachycardia, and hypertension 
• Central Nervous System 
−Headache or dizziness 
- Reversible posterior leukoencephalopathy syndrome 
- Hydrocephalus 
• Digestive

Confidential  
17 
 
−Constipation, diarrhea, non-specific abdominal pain, nausea, gastroesophageal reflux, 
stomatitis esophageal candidiasis, vomiting, and biliary or bowel obstruction or 
perforation,pancreatitis, enteritis, colovesical fistula 
• Haematologic and lymphatic 
−Ecchymosis, anemia, neutropenia, and thrombocytopenia  
• Investigations/Laboratory 
−Elevated liver function tests, generally CTC/CTCAE grade 1-2. Preliminary data 
suggests these are reversible, in some cases even while continuing therapy. 
• Metabolic and nutritional 
−Anorexia, dehydration, hypokalaemia, hypomagnesaemia, hypercalcemia and 
hypophosphataemia 
• Skin and appendages 
Acneiform rash, pruritus, macular or maculopapular rash (generalised or 
localised), localised and generalised erythema, photosensitivity reaction, and sweating. 
On occasion, especially when given with chemotherapy, these have progressed to more 
serious conditions, including exfoliative dermatitis, skin desquamation, erythroderma, 
toxicoderma, toxic epidermal necrolysis, erythema multiforme and necrotizing fasciitis. 
- Wound healing complications 
- Hand-foot syndrome 
• Respiratory 
−Interstitial lung disease, pulmonary effusion and pneumonia. A very small number of 
patients with lung cancer receiving vandetanib have developed shortness of breath and 
cough because of inflammation or scar tissue formation in the lungs, although this could 
be due to the underlying lung cancer. 
• Renal 
−Proteinuria, haematuria and renal failure. 
• Vascular 
−Arterial ischaemic events (including myocardial infarction, stroke, peripheral 
ischaemia), venous thromboembolism (including pulmonary embolism). A small number 
of patients receiving vandetanib have developed blood clots affecting the legs or lungs. 
This may have been due to the patient’s cancer or other illness at the time; however, it is 
considered possible that vandetanib might increase the risk for developing blood clots. 
-- Intracranial bleeding 
• Psychiatric  
−Mood disorders (anxiety, depression, insomnia). It is possible that these events are not 
direct effects of vandetanib, but rather are secondary to symptoms of cancer or to other 
effects of vandetanib (rash, etc). 
• Ophthalmologic 
−Corneal changes, including ulceration 
 
• General 
−Asthenia, fever, weight loss, pain, and fatigue 
 
In addition, a number of other side effects have been reported in clinical trials using ZD6474 
alone, in combination with other chemotherapy agents or radiation. It is unclear whether these 
side effects are related to ZD6474, or are caused by other factors (such as chemotherapy or

radiation). These side effects include: 
• Infections, including life-threatening bacterial infections 
• Seizures and facial nerve palsies 
• Syncope 
• LV dysfunction 
• Respiratory failure 
• Esophageal fistula 
 
Hemorrhage from both tumor and non-tumor sites have been described with several agents 
targeting the VEGF pathway (such as sunitinib, sorafenib, bevacizumab etc.). Episodes of 
bleeding with the above agents have been occasionally life-threatening or fatal. Experience with 
anti-VEGF agents in VHL patients is limited and largely anecdotal. We are aware of one case of 
cerebellar hemorrhage requiring neurosurgical intervention in a VHL patient receiving the 
experimental VEGFR tyrosine kinase inhibitor (PTK787, Dr. Dan George, Duke University, 
Personal Communication). Gingival bleeding as well as one case each of hemoptysis and 
cerebellar hemorrhage has been described in studies with ZD6474, although it is unclear whether 
these events are attributable to the agent. A risk of serious bleeding events cannot be excluded in 
patients receiving this drug.  
 
1.2.6 Rationale     
Localized clear cell renal carcinoma in VHL patients requires surgical therapy, which often 
needs to be repeated multiple times.  The surgical therapy is not curative, but is recommended in 
order to decrease the likelihood of metastasis.  Once metastasis has occurred, clear cell renal 
cancer is incurable in the majority of VHL patients with currently available therapies.  
 
Insight into the molecular pathways believed to mediate the VHL phenotype has provided the 
impetus for the development of rational targeted therapeutic strategies directed against this 
condition. Inactivation of the VHL gene, the underlying molecular defect in VHL, results in 
decreased ubiquitin-dependent degradation of hypoxia-inducible factors (HIFs), which in turn 
leads to overexpression of VEGF as well as other genes such as transforming growth factor-
(TGF-), platelet derived growth factor (PDGF) and GLUT-1. Overexpression of VEGF is 
responsible for enhanced tumor angiogenesis and leads to the highly vascular renal tumors seen 
in VHL patients. ZD6474 inhibits angiogenesis by inactivation of the tyrosine kinase activity of 
the VEGF receptor KDR/VEGFR2. In addition, ZD6474 may exert direct antitumor activity via 
its inhibition of EGF- R, one of the ligands for which is TGF-. ZD6474 has shown activity in 
several preclinical tumor models and has demonstrated an acceptable toxicity profile in phase I 
and phase II studies. ZD6474 thus provides an exciting opportunity for exploring a targeted 
approach in a hereditary syndrome with a well characterized molecular defect and no available 
curative options.

(http://home.ccr.cancer.gov/intra/eligibility/welcome.htm) 
must be completed and faxed to 301-480-0757.  After confirmation of eligibility at Central 
Registration Office, CRO staff will call the pharmacy to advise them of the acceptance of the 
patient on the protocol prior to the release of any investigational agents.  Verification of 
Registration will be forwarded electronically via e-mail.  Please note, it is very important for all 
registrars to acquire encrypted e-mail from NIH Help Desk, since the verification of registration 
includes patient’s information.  A recorder is available during non-working hours.  The Central 
Registration Office will be notified when a patient is withdrawn from the study.

STUDY IMPLEMENTATION 
3.1 
STUDY DESIGN 
This is a phase II study utilizing a fixed dose of ZD6474 (300mg/day PO). The study will recruit 
patients with von Hippel Lindau disease who have at least one measurable renal tumor (either 
localized to the kidneys and/or metastatic). Based on phase I evaluation, 300mg/day was 
identified as a well tolerated dose and appears to result in serum concentrations of the drug 
compatible with inhibition of target receptor tyrosine kinases. Treatment cycles will consist of 28 
days and the drug will be administered daily on days 1-28. There will be no break between 2 
consecutive cycles (i.e, drug administration will be continuous). Patients will undergo clinical 
and laboratory evaluation in the Urologic Oncology Branch clinic prior to the start of each cycle. 
Patients will be evaluated radiologically for evidence of response or progression approximately 
twelve weeks after initiation of therapy and every twelve weeks thereafter while on study. 
Patients with evidence of stable disease or disease response in renal tumors (CR or PR) will 
continue to receive therapy in the absence of serious toxicity. Patients who demonstrate disease 
progression at any time will be taken off study. Patients who continue to demonstrate at least one 
tumor >3cm following 12 weeks or more of therapy may be taken off study regardless of 
response status, if, in the opinion of the PI, this lesion(s) poses a significant risk of metastasis in 
the absence of surgical intervention or could otherwise compromise patient care. These patients 
will be evaluable for the primary end-point (disease response). 
 
Non-renal VHL associated lesions are usually followed until they reach a certain size or become 
symptomatic, at which point surgical resection or other treatments (such as laser 
photocoagulation of retinal angiomas) of these lesions is pursued. It is also conceivable, although 
unlikely, that patients with pheochromocytomas or pancreatic neuroendocrine tumors may 
develop metastatic disease that may necessitate chemotherapy. Patients with progression of non-
renal lesions requiring systemic antineoplastic therapy or surgical intervention will discontinue 
study drug even in the absence of renal progression or unacceptable toxicity. Vandetanib may be 
restarted in patients undergoing resection of non-renal VHL lesions once the surgical incisions 
have adequately healed, if in the opinion of the PI, this is likely to offer clinical benefit (e.g. 
patients demonstrating an ongoing response in their renal tumors while on vandetanib).  Patients 
with progression of non-renal lesions not requiring intervention but demonstrating stable or 
responding renal lesions will continue ZD6474 at the discretion of the PI/Study Chair.

3.2 
STUDY DRUG ADMINISTRATION 
ZD6474 Administration  
Treatment will be will be self-administered by the patient on an outpatient basis.  The starting 
dose of ZD6474 is 300mg/day administered PO daily. Patients with moderate renal failure 
defined as creatinine clearance > than or = 30ml/min and <50ml/min should begin vabdetanib at 
a reduced dose of 200mg.  ZD6474 should be taken with some food and water to minimize GI 
effects, ideally at around the same time every morning. ZD6474 is available as 50mg, 100mg, 
200mg and 300mg tablets and as an oral solution (15 mL of 10mg/mL vandetanib in 25 mg oral 
solution bottles). Patient compliance will be tracked using a pill count/administration form which 
the patient will be instructed to complete and which will be reviewed at each clinic visit.   If the 
subject inadvertently does not take the dose in the morning, he or she may take that day’s dose 
any time up to10pm that same day.  However, if a subject misses taking their scheduled dose and 
is unable to take the missed dose on the same day, he or she must take the next scheduled dose 
and the missed dose will not be made up. 
 
Reported adverse events and potential risks are described in Section 8.  Appropriate dose 
modifications for ZD6474 are described in Section 3.3.  No investigational or commercial agents 
or therapies other than those described below may be administered with the intent to treat the 
patient’s malignancy.  
 
3.3 
DOSING DELAYS/DOSE MODIFICATIONS 
Patients will be asked to record side effects/symptoms developing or worsening on therapy on a 
Side Effect Diary which will be reviewed by the research nurse/PI/associate investigator during 
clinic visits. Treatment modifications will be made in the event of toxicities (graded based on 
NCI Common Toxicity Criteria for Adverse Events, version 3.0) according to the guidelines 
below, with dose levels as defined below:  
Dose level   0: 300mg/day 
Dose level  -1: 200mg/day

3.3.1 Management of Skin Toxicity 
 
Patients will be instructed to follow a program of sun protective measures while receiving study 
therapy and for 3-4 weeks after discontinuing study therapy.  These measures include 
minimizing sun-exposure, using protective clothing, hats etc., and the use of sunscreens. The aim 
is to reduce the risk of development of skin rash, minimize the severity of skin rash, and to 
minimize the requirement for dose reduction of study therapy. 
 
If a patient develops a skin rash,  
The rash should be graded/assessed by a physician as soon as possible according to the CTCAE 
cutaneous toxicity criteria and documented accordingly 
If a rash of CTCAE grade 2 or higher is detected, symptomatic treatment should be provided.

A variety of agents can be used to manage skin rashes and associated symptoms.  These include 
mild to moderate strength steroid creams or oral corticosteroids, topical or systemic antibiotics, 
topical or systemic antihistamines, emollients and occasionally retinoid creams. 
If a rash of CTCAE grade 3 is detected, ZD6474 should be withheld until recovery to grade 1 or 
below, at which point, the drug may be restarted at one dose level lower 
Patients with CTCAE grade 4 rash will discontinue therapy and will not be retreated. 
If grade 3 higher cutaneous toxicity recurs at reduced dose of ZD6474, the patient will 
permanently discontinue study treatment of ZD6474.  If ZD6474 must be withheld for >3 weeks 
due to cutaneous toxicity, the patient will be taken off study. 
3.3.2 Management of gastrointestinal (GI) toxicity 
If GI toxicity is not appropriately managed this may be associated with a development of 
dehydration.  Electrolytes should be monitored in the event of persistent vomiting or diarrhea. 
 
3.3.2.1 Nausea and/or vomiting 
In subjects who have emesis and are unable to retain study treatment, every attempt should be 
made to obtain control of nausea and vomiting.  The dose of study treatment may be repeated if 
emesis occurs within 30 minutes of taking the tablets or all the tablets are seen in the emesis.  
Nausea, vomiting, or both may be controlled with antiemetic therapy; however, 5HT-3 
antagonists are not permitted because of the potential effect on QTc interval.  
 
3.3.2.2 Diarrhea 
 
Diarrhea should be treated with standard medications to avoid dose modification or interruption, 
if possible.  Diarrhea related to ZD6474 has been successfully managed with anti-diarrheal 
agents such as loperamide. Once diarrhea is determined to be related to ZD6474, an acceptable 
strategy for symptomatic management is initiation of loperamide 2mg po administered following 
the first episode, which can be repeated as frequently as every 2 hours while awake (or 
administered at a dose of 4mg every 4 hours during sleeping hours) (not to exceed a total of 
16mg/24 hours) until the patient is diarrhea-free for 8-12 hours.  
 
No dose modifications will be made for CTCAE grade 1 or 2 nausea, vomiting or diarrhea.  If 
CTCAE grade 3 nausea, vomiting, or diarrhea develops despite optimal pharmacologic 
prophylaxis/treatment, study medication should be withheld until symptoms resolve to less than 
or equal to grade 1.  Once the diarrhea resolves to less than or equal to grade 1, treatment with 
ZD6474 may recommence with a dose reduction of one level.  If the toxicity reoccurs on the 
dose reduction pack, the subject will be withdrawn from the study. Subjects who develop grade 4 
nausea, vomiting, or diarrhea will discontinue therapy with ZD6474. Subjects who are clinically 
unstable because of nausea, vomiting, diarrhea or other intercurrent medical illness must be 
admitted and evaluated using telemetry until clinically stable. 
 
3.3.3 QT prolongation 
QT prolongation will be managed as follows:

08-C-0020 Amendment H 
Abbreviated Title: Phase II of ZD6474 in VHL 
 
Confidential

Monitoring for QT prolongation 
All patients on study will get a weekly 12 lead EKG for the first 2 cycles. Thereafter (in the 
absence of QT prolongation), a monthly ECG will be performed while the patient is on the study 
drug. The following algorithm will be used to monitor/manage QTc prolongation. 
 
QTc prolongation is defined as  
A single QTc value of ≥500 msec or an increase of ≥100 msec from baseline;  
OR 
 
Two QTc measurements where either of the following criteria are met for both QTc values (the 
second being the mean of 3 consecutive ECGs):  
A QTc interval ≥500 msec but <550 msec,  OR 
An increase of ≥60 msec, but <100 msec, from baseline QTc to a QTc value ≥480 msec.   
Management of Patients With QTc Prolongation 
 
For a single QTc value of ≥500 msec or an increase of ≥100 msec from baseline, ZD6474 must 
be withheld.  ECGs and electrolytes should be followed 3 times a week until QTc falls below 
480 msec or baseline, whichever is higher.  ZD6474 treatment may be resumed at a lower dose 
after the QTc recovers to <480 msec or baseline. 
 
For a QTc ≥500ms but <550ms (grade 3 CTCAE v3.0) or ≥60ms, but <100ms compared to 
baseline to a QTc value ≥480 msec, further ZD6474 dosing will be withheld and an ECG (in 
triplicate) obtained within 24 hours. If the repeat ECGs confirm a QTc ≥500 (mean calculated 
from 3 ECGs) or prolongation of ≥60ms from baseline to a QTc ≥480ms, QTc and electrolytes 
will be monitored three times a week until the QTc returns to baseline or below 480ms 
(whichever is higher); thereafter, ZD 6474 will be resumed at one lower dose level. If the repeat 
ECG reveals a QTc <500 ms or a prolongation of <60ms from baseline, ZD6474 will be resumed 
at the current dose and an ECG repeated in 48 hours and thereafter as outlined in the study plan 
in the absence of QT prolongation (i.e, ≥500ms or prolongation ≥60ms from baseline to a value 
≥480 msec). A second instance of QTc ≥500ms (but <550ms) or QTc prolongation ≥60ms from 
baseline to a value ≥480 msec will necessitate withholding drug until normalization of QTc and 
resumption thereafter at one lower dose level.

3.3.4 Hypertension 
Subjects will be asked to monitor their blood pressure at home at least once a day and contact the 
UOB team for elevated readings. However, elevated BP readings should be confirmed by a 
qualified health care professional and decisions regarding grading of hypertension and 
initiation/intensification of antihypertensive therapy will be driven by BP measurements 
performed by a health care professional. Table 1 outlines the management plan for patients 
developing hypertension on therapy. Although CTCAE criteria will be used to grade 
hypertension, the scheme outlined in Table 1 will be used to guide dose modifications. Early 
treatment of grades 1-2 hypertension to prevent or minimize the risk of developing more 
persistent or clinically significant hypertension is allowed and is not considered a grade 3 event. 
 
Agents typically used to treat hypertension include calcium channel blockers such as amlodipine 
(agents such as verapamil or diltiazem, which are potents inhibitors of CYP3A4 should be 
avoided where possible, as should agents in this category that have the potential to prolont QTc), 
diuretics, ACE inhibitor, beta-blockers and angiotensin receptor antagonists. The choice of 
agents and dosage used may vary based on individual circumstances.

there are no permanent sequelae. Patient 
will be removed from study if a second 
episode of grade 4 hypertension occurs 
 
3.3.5 Other Toxicity 
If any other CTCAE grade 3 or 4 non hematologic toxicity attributable to ZD6474 develops (not 
outlined in Section 3.3.1-3.3.4), study treatment should be interrupted until the toxicity resolves 
to less than or equal to CTCAE grade 1 or baseline.  At the time of resolution, patients with 
grade 3 toxicity may resume study treatment at one dose level lower. Patients with grade 4 
nonhematologic toxicity will discontinue ZD6474 and be taken off study. Patients with grade 3 
or 4 neutropenia or thrombocytopenia attributable to ZD6474 will have their therapy interrupted 
until resolution to less than or equal to CTCAE grade 1 or baseline, at which point treatment may 
be resumed at one dose level lower. If study treatment must be interrupted for more than 3 weeks 
to allow for toxicity to resolve, the subject’s participation in the study will be discontinued. Dose 
reductions or study drug interruptions will not be made for laboratory abnormalities not 
considered clinically significant, regardless of grade.

RESEARCH STUDIES 
Sample acquisition and planned studies 
 
Blood samples for evaluation of basal plasma levels of angiogenesis biomarkers such as VEGF 
and to assess the effect of ZD6474 on these biomarkers will be obtained on study entry and at 
each clinic visit. 5-10 cc of venous blood will be collected into lavender top EDTA tubes and 
thoroughly mixed.  
 
Peripheral blood (four CPT tubes containing sodium citrate) will be obtained pre-treatment and 
post-treatment with ZD6474 and coded samples will be used for analysis of angiogenesis 
markers such as circulating endothelial cells (CEC) and circulating endothelial progenitor cells 
(CEP). The time points may vary as the optimal time vis a vis treatment needs to be empirically 
determined.  Four CPT tubes containing sodium citrate (blue-black speckled top tubes) of 
peripheral blood will be sent to Jane Trepels’s laboratory in the Medical Oncology Branch, CCR, 
NCI.  The CEC and CEP analysis will be performed using multiparameter flow cytometry, and 
may include ancillary studies such as real-time RT-PCR analysis of gene expression and in vitro 
endothelial cell culture.  These studies are exploratory and intended to evaluate the utility of 
CECs and CEPs as surrogates for inhibition of angiogenesis following administration of 
ZD6474.  
 
Although there is no universally accepted surrogate for angiogenesis inhibition, evaluation of 
CECs and CEPs have been proposed and validated by several groups (41-46). Dr. Jane Trepel’s 
lab has collaborated with other groups (Dr. John Heymach, MD Anderson Cancer Center, and 
the Angiogenesis Core at the Beth Israel and Deaconess Medical Center) to standardize flow 
cytometric analyses of peripheral blood for evaluation of CEC/CEP. For this analysis, peripheral 
blood is drawn into 4 CPT citrate tubes. Mononuclear cells are isolated by centrifugation, 
washed with PBS, and FcR solution (Miltenyi) is added to block non-specific binding.  Although 
the entibodies and fluorochromes used may vary, for identification of CECs and CEPs, cells are 
typically stained with FITC- conjugated anti-CD31, PerCP-conjugated anti-CD45, APC-
conjugated anti-CD133, Hoechst 33258 and PE-conjugated CD146 and analysed on an LSR II 
flow cytometer (BD Biosciences), using LSR II-equipped digital data acquisition and FlowJo 
cytometric data analysis software. The CEC and CEP cell concentrations are calculated as a 
percentage of the total number of mononuclear cells or as the number of cells/microliter of whole 
blood after an evaluation of a minimum of 105 cellular events, and preferably 106 cellular events.  
CEC cells are defined by the co-expression, or absence of expression on a single cell of the 
following parameters: CD45-, CD31+, CD133- and CD146+, Hoechst 33258 (viable CEC) or 
CD45-, CD31+, CD133- and CD146+, Hoechst 33258+ (nonviable CEC).  CEP cells are defined 
by the co-expression, or absence of expression on a single cell of the following parameters: 
CD45- or dim, CD31+, CD133+ and CD146-, Hoechst 33258- (viable CEP) or CD45- or dim, 
CD31+, CD133+ and CD146-, Hoechst 33258+ (nonviable CEP). 
 
The outcome measures will be the number of CEC and CEP per 106 mononuclear cells or per 
microliter of peripheral blood, analyzed in samples taken before and after treatment.  These 
numbers will then be examined for correlations with various parameters to assess their potential 
utility as surrogate biomarkers for drug activity, for establishing the optimal biologic dose, for 
patient stratification, and monitoring of therapy-related side effects.

In addition to multi-parameter flow CEC and CEP analysis, if there are a sufficient number of 
cells in the mononuclear fraction the cells will be set up in vitro, according to standard methods, 
for the endothelial progenitor cell colony forming assay (47, 48). 
 
Correlative laboratory studies will be performed by investigators in the Urologic Oncology 
Branch and may involve collaboration with other NIH intramural investigators and/or Astra-
Zeneca. Studies listed will be performed wherever possible and as permitted by sample and 
resource availability.  
 
3.4.1 Collection, Storage, Use and Disposition of Human Specimens 
3.4.1.1 Clinical Samples  
Blood and urine samples for clinically relevant, non-research hematology, serum 
chemistry, urinalysis, and skin biopsy tissue will be prepared using standard procedures.  
Routine clinical analyses will be performed by the NIH Clinical Center central 
laboratories or NCI Pathology department.  Samples will be processed and disposed 
according to standard laboratory procedure. 
 
3.4.1.2  Storage and research use of research human specimens  
a) Sample Collection and Planned Research Studies-Research samples will be collected 
with a view to performing a variety of correlative/biomarker studies (as indicated in 
section 3.4).  
b) Sample Processing and Storage-Each patient research sample will be assigned a 
unique patient identifier and relevant sample characteristics (such as timing of sample 
collection, treatment cycle and day identifiers) will be recorded. The location of all 
samples will be carefully tracked in the database.    All stored samples will be coded 
and no identifying patient information will be on placed on sample containers. Stored 
samples will be kept in freezers / refrigerators or secure containers located in the 
Urologic Oncology Branch research laboratories.  
c) Time frame for research studies- Samples will be stored until requested by an 
authorized researcher(s).  All researchers are required to use the samples for research 
purposes associated with this trial (as per the NCI IRB approved protocol). Subjects 
will be given the option of consenting to future use of their research samples per the 
informed consent process with their option declared in the consent document.  
Samples from those patients who consent to this will be stored permanently. 
However, these samples will be used only for research studies on active NCI IRB 
approved protocols covered by a valid informed consent document. Samples will be 
destroyed at the completion of the study from those subjects who decline future use of 
their samples. Once primary research objectives for the protocol are achieved, 
intramural researchers can request access to remaining samples provided they have an 
IRB approved protocol and patient consent. Any unused samples must be returned to 
the UOB laboratories as appropriate. The PI will report destroyed samples to the IRB 
if samples become unsalvageable because of environmental factors (e.g. broken 
freezer or lack of dry ice in a shipping container) or if samples are destroyed because 
a patient withdraws consent. Samples will also be reported as lost if they are lost in 
transit between facilities or misplaced by a researcher.  Any freezer problems, lost

samples or other problems associated with samples will be reported to the IRB, the 
NCI Clinical Director, and the office of the CCR, NCI.

CONCURRENT THERAPIES 
Coadministration of ZD6474 and drugs with potent CYP3A4 inducer effects are not allowed. 
Agents with potent inhibitory effects on CYP3A4 should be avoided where possible.  (Please see 
Appendix D) Other agents with some modulation of and/or metabolization through CYP3A4 can 
be used with caution at the discretion of the Principal Investigator ZD6474 should also not be 
administered in patients receiving drugs known to prolong QT interval or induce torsades de 
point. (Please see Appendix C). No concurrent systemic anti-neoplastic therapy for VHL-
associated tumors will be allowed. 
 
3.8 
SURGICAL GUIDELINES 
Major elective surgical procedures should not be scheduled during protocol treatment or within 4 
weeks of the last dose of drug. Patients undergoing unexpected major surgical procedures should 
have ZD6474 withheld. Treatment may be resumed at a later date at the discretion of the PI, no 
earlier than 4 weeks post-operatively, with adequately healed incisions.  
 
3.9 
OFF STUDY CRITERIA/OFF TREATMENT CRITERIA 
 In the absence of treatment delays due to adverse event(s), treatment may continue until one of 
the following criteria applies: 
• Disease progression per RECIST criteria of targeted renal lesions  
• Disease progression of non-renal lesions requiring surgical intervention or systemic anti-
neoplastic therapy. Vandetanib may be restarted in patients undergoing resection of non-
renal VHL lesions once the surgical incisions have adequately healed, if in the opinion of 
the PI, this is likely to offer clinical benefit (e.g. patients demonstrating an ongoing 
response in their renal tumors while on vandetanib).  
• Intercurrent illness that prevents further administration of treatment, 
• Unacceptable adverse event(s) that necessitates discontinuation of ZD6474, including 
most grade 4 and recurrent grade 3 toxicities (CTCAE v3) as outlined in section 3.3 as 
well as any other adverse event that renders further treatment unsafe in the opinion of the 
investigator  
• Patient decides to withdraw from the study, or 
• General or specific changes in the patient’s condition render the patient unacceptable for 
further treatment in the judgment of the investigator. 
In the event of a complete radiologic response, treatment will continue for 2 cycles beyond CR. 
Patients may be retreated at the discretion of the PI in the event of disease recurrence. 
3.10 POST-TREATMENT FOLLOW-UP 
Patients with unresolved toxicities (to ≤CTCAE 3.0 grade 1) may be followed to enable 
monitoring and/or management of these toxicities. Patients may be followed-up by telephone or 
other means of communication periodically to determine disease status.

DATA COLLECTION AND EVALUATION 
5.1 
DATA COLLECTION 
Data will be prospectively collected and entered in a designated database (C3D). All 
radiographic images will be stored in the Dept. of Radiology, Clinical Center, NIH and will be 
reviewed by a medically responsible investigator and/or a clinical center radiologist. 
 
For the purposes of this study, patients should be reevaluated for response every 12 weeks.  In 
addition to a baseline scan, confirmatory scans should also be obtained 4 weeks following initial 
documentation of objective response. 
 
The PI will be responsible for overseeing entry of data into an in-house password protected 
electronic system and ensuring data accuracy, consistency and timeliness. The principal 
investigator, associate investigators/research nurses and/or a contracted data manager will assist 
with the data management efforts.  All data obtained during the conduct of the protocol will be 
kept in secure network drives or in approved alternative sites that comply with NIH security 
standards. Primary and final analyzed data will have identifiers so that research data can be 
attributed to an individual human subject participant. 
End of study procedures: Data will be stored according to HHS, FDA regulations and NIH 
Intramural Records Retention Schedule as applicable.  
Loss or destruction of data: Should we become aware that a major breech in our plan to protect 
subject confidentiality and trial data has occurred, the IRB will be notified.  
 
5.2 
RESPONSE EVALUATION 
5.2.1 Definitions 
Response and progression of renal tumors will be evaluated in this study using the new 
international criteria proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) 
Committee [JNCI 92(3):205-216, 2000].  Changes in only the largest diameter (unidimensional 
measurement) of the tumor lesions are used in the RECIST criteria. Note:  Lesions are either 
measurable or non-measurable using the criteria provided below. The term “evaluable” in 
reference to measurability will not be used because it does not provide additional meaning or 
accuracy. 
5.2.1.1 Measurable disease 
Measurable lesions are defined as those that can be accurately measured in at least one 
dimension (longest diameter to be recorded) as >20 mm with conventional techniques (CT, MRI, 
x-ray) or as >10 mm with spiral CT scan.  All tumor measurements must be recorded in 
millimeters (or decimal fractions of centimeters).  
 
5.2.1.2  Non-measurable disease 
All other lesions (or sites of disease), including small lesions (longest diameter <20 mm with 
conventional techniques or <10 mm using spiral CT scan), are considered non-measurable 
disease.  Bone lesions, leptomeningeal disease, ascites, pleural/pericardial effusions, 
lymphangitis cutis/pulmonis, inflammatory breast disease, abdominal masses (not followed by 
CT or MRI), and cystic lesions are all non-measurable. 


Version Date: 11-16-2016 
08-C-0020 Amendment H 
Abbreviated Title: Phase II of ZD6474 in VHL 
 
Confidential  
35 
 
5.2.1.3 Target lesions 
All measurable RCC lesions up to a maximum of five lesions per kidney and a total of ten 
lesions should be identified as target lesions and recorded and measured at baseline. Target 
lesions should be selected on the basis of their size (lesions with the longest diameter) and their 
suitability for accurate repeated measurements (either by imaging techniques or clinically).  A 
sum of the longest diameter (LD) for all target lesions will be calculated and reported as the 
baseline sum LD.  The baseline sum LD will be used as reference by which to characterize the 
objective tumor response. 
 
5.2.1.4 Non-target lesions 
All other lesions (or sites of disease) should be identified as non-target lesions and should also 
be recorded at baseline.  Non-target lesions include measurable lesions that exceed the maximum 
numbers per organ or total of all involved organs as well as non-measurable lesions.  
Measurements of these lesions are not required, but the presence or absence of each should be 
noted throughout follow-up. If the lesions are too numerous to list, not all lesions may be listed 
at the discretion of the investigator and/or radiologist. 
 
5.2.2 Guidelines for Evaluation of Measurable Disease 
All measurements should be taken and recorded in metric notation using a ruler or calipers.  All 
baseline evaluations should be performed as closely as possible to the beginning of treatment and 
never more than 4 weeks before the beginning of the treatment. For each restaging study, lesions 
will be recorded in the same order as with the baseline study. 
 
Note: Tumor lesions that are situated in a previously irradiated area might or might not be 
considered measurable.   
 
The same method of assessment and the same technique should be used to characterize each 
identified and reported lesion at baseline and during follow-up. Imaging-based evaluation is 
preferred to evaluation by clinical examination when both methods have been used to assess the 
antitumor effect of a treatment. 
 
Clinical lesions.  Clinical lesions will only be considered measurable when they are superficial 
(e.g., skin nodules and palpable lymph nodes).  In the case of skin lesions, documentation by 
color photography, including a ruler to estimate the size of the lesion, is recommended.  
 
Chest x-ray.  Lesions on chest x-ray are acceptable as measurable lesions when they are clearly 
defined and surrounded by aerated lung.  However, CT is preferable.  
 
Conventional CT and MRI.  These techniques should be performed with cuts of 10 mm or less 
in slice thickness contiguously.  Spiral CT should be performed using a 5 mm contiguous 
reconstruction algorithm.  This applies to tumors of the chest, abdomen, and pelvis.  Head and 
neck tumors and those of extremities usually require specific protocols. 
 
Ultrasound (US).  When the primary endpoint of the study is objective response evaluation, US 
should not be used to measure tumor lesions.  It is, however, a possible alternative to clinical 


Version Date: 11-16-2016 
08-C-0020 Amendment H 
Abbreviated Title: Phase II of ZD6474 in VHL 
 
Confidential  
36 
 
measurements of superficial palpable lymph nodes, subcutaneous lesions, and thyroid nodules.  
US might also be useful to confirm the complete disappearance of superficial lesions usually 
assessed by clinical examination. 
 
Endoscopy, Laparoscopy.  The utilization of these techniques for objective tumor evaluation 
has not yet been fully and widely validated.  Their uses in this specific context require 
sophisticated equipment and a high level of expertise that may only be available in some centers.  
Therefore, the utilization of such techniques for objective tumor response should be restricted to 
validation purposes in reference centers. However, such techniques may be useful to confirm 
complete pathological response when biopsies are obtained. 
 
Tumor markers.  Tumor markers alone cannot be used to assess response.  If markers are 
initially above the upper normal limit, they must normalize for a patient to be considered in 
complete clinical response.  Specific additional criteria for standardized usage of prostate-
specific antigen (PSA) and CA-125 response in support of clinical trials are being developed. 
 
Cytology, Histology.  These techniques can be used to differentiate between partial responses 
(PR) and complete responses (CR) in rare cases (e.g., residual lesions in tumor types, such as 
germ cell tumors, where known residual benign tumors can remain). 
 
5.2.3 Response Criteria 
5.2.3.1 Evaluation of target lesions 
Complete Response (CR): 
Disappearance of all target lesions 
 
Partial Response (PR): 
 
At least a 30% decrease in the sum of the 
longest diameter (LD) of target lesions, taking 
as reference the baseline sum LD 
 
Progressive Disease (PD): 
At least a 20% increase in the sum of the LD of 
target lesions, taking as reference the smallest 
sum LD recorded since the treatment started or 
the appearance of one or more new lesions 
 
Stable Disease (SD):  
 
Neither sufficient shrinkage to qualify for PR 
nor sufficient increase to qualify for PD, taking 
as reference the smallest sum LD since the 
treatment started 
 
5.2.3.2 Evaluation of non-target lesions 
Complete Response (CR): 
Disappearance of all non-target lesions and 
normalization of tumor marker level 
 
Incomplete Response/ 
Stable Disease (SD):  
Persistence of one or more non-target lesion(s) 
and/or maintenance of tumor marker level above 


Version Date: 11-16-2016

the normal limits 
 
Progressive Disease (PD): 
Appearance of one or more new lesions and/or 
unequivocal progression of existing non-target 
lesions 
 
Although a clear progression of “non-target” lesions only is exceptional, in such circumstances 
the opinion of the treating physician should prevail, and the progression status should be 
confirmed at a later time by the review panel (or study chair). 
Note:  If tumor markers are initially above the upper normal limit, they must normalize for a 
patient to be considered in complete clinical response. 
 
5.2.3.3 Evaluation of best overall response 
The best overall response is the best response recorded from the start of the treatment until 
disease progression/recurrence (taking as reference for progressive disease the smallest 
measurements recorded since the treatment started).  The patient's best response assignment will 
depend on the achievement of both measurement and confirmation criteria.

Note: 
 
• Patients with a global deterioration of health status requiring discontinuation of 
treatment without objective evidence of disease progression at that time should be 
classified as having “symptomatic deterioration.”  Every effort should be made to 
document the objective progression, even after discontinuation of treatment. 
 
• In some circumstances, it may be difficult to distinguish residual disease from 
normal tissue.  When the evaluation of complete response depends on this 
determination, it is recommended that the residual lesion be investigated (fine 
needle aspirate/biopsy) before confirming the complete response status.

5.2.4 Confirmatory Measurement/Duration of Response 
5.2.4.1 Confirmation 
To be assigned a status of PR or CR, changes in tumor measurements must be confirmed 
by repeat assessments that should be performed ≥ 4 weeks after the criteria for response 
are first met.  In the case of SD, follow-up measurements must have met the SD criteria 
at least once after study entry at a minimum interval of 8 weeks 
 
5.2.4.2 Duration of overall response 
The duration of overall response is measured from the time measurement criteria are met 
for CR or PR (whichever is first recorded) until the first date that recurrent or progressive 
disease is objectively documented (taking as reference for progressive disease the 
smallest measurements recorded since the treatment started). 
 
The duration of overall CR is measured from the time measurement criteria are first met 
for CR until the first date that recurrent disease is objectively documented. 
 
5.2.4.3 Duration of Stable Disease 
Stable disease is measured from the start of the treatment until the criteria for progression 
are met, taking as reference the smallest measurements recorded since the treatment 
started.  
 
5.2.5 Evaluation of non-renal tumors associated with VHL 
Evaluation of the effect of ZD6474 on non-renal tumors associated with VHL disease is one of 
the secondary end-points of this study. Since there is significant interpatient variability in the 
location and number of visceral and non-visceral tumors, each tumor type will be assessed 
individually. In each individual patient, the presence of one or more of the following tumors at 
baseline will be documented and response following treatment with ZD6474 will be assessed: 
 
1) Pancreatic tumors/cysts 
2) CNS Hemangioblastomas 
3) Pheochromocytomas 
 
5.2.5.1 Identification and measurement of lesions to be followed, and response criteria will 
follow the scheme outlined in Sections 5.2.1 to 5.2.4 
 
5.2.5.2 Evaluation of retinal angiomas will include the following:  
a) Measurement of visual acuity 
b) Size-Largest unidimensional measurements will be recorded where 
appropriate 
c) Visual field evaluation 
d) Fluorescein leakage 
Since standard tumor response criteria such as RECIST cannot be applied to ocular 
lesions, changes in the above parameters will be recorded descriptively.

5.2.5.3 Patients with progressive disease in non-renal lesions which require medical or surgical 
intervention shall be taken off study for progressive disease.  Patients with progressive 
disease in non-renal lesions not requiring intervention but stable disease or responding 
disease in renal lesions will be continued on ZD6474 to the discretion of the PI or Study 
Chair.

TOXICITY CRITERIA 
CTCAE term (AE description) and grade:  The descriptions and grading scales found in the revised 
NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for AE 
reporting.  All appropriate treatment areas should have access to a copy of the CTCAE version 4.0.  A 
copy of the CTCAE version 4.0 can be downloaded from the CTEP web site (http://ctep.cancer.gov)

STATISTICAL SECTION 
 
This is a phase II study to establish whether treatment of ZD6474 in patients with von Hippel 
Lindau disease and renal tumors results in an adequate fraction of clinical responses (partial 
response plus complete response) to warrant further development. The study will be conducted 
with a Simon two-stage optimal design (Simon R. Controlled Clinical Trials 10:1-10;1989) 
which allows for an early look for futility. For the purposes of phase II evaluation, clinical 
response will be defined as either a partial or complete response occurring at any time after 
initiation of therapy. All responses must be confirmed ≥ 4 weeks after the initial response is 
documented.  Twelve patients will be accrued into the first stage. If 1 or more of the 12 patients 
respond, accrual will proceed to the second stage of the design. Twenty-five additional patients 
will be accrued in the second stage for a total accrual of 37 patients. If 4 or more of 37 respond, 
ZD6474 will be considered worthy of further investigation in this population. If fewer than 4 
patients of 37 respond, the agent will be considered to have insufficient activity for further 
investigation.  If after the first 12 patients have been accrued to the study, no patient has had a 
confirmed response, further accrual will be temporarily suspended for up to a year or until at 
least one response is seen; if no responses are seen within one year of accrual of the twelfth 
patient, no further patients will be accrued and the study will not proceed to the second stage.  
 
6.1 
TWO-STAGE DESIGN 
The optimal two-stage design is based on the following design parameters. The fraction of 
clinical responses is 5% if the agent is ineffective (P0=0.05), while a fraction of clinical 
responses of 20% (P1=0.2) will be considered worthy of further testing.  The probability of 
falsely concluding that the agent is effective when it is truly ineffective is 0.1 (alpha) and the 
probability of falsely concluding that the agent is ineffective when it is truly effective is 0.1 
(beta).  Under this design, the probability of stopping accrual early if the proportion of responses 
is 5% is 54%. 
 
6.2 
RESPONSE FREQUENCY 
The response frequency for non-renal tumors associated with VHL will be estimated as a 
secondary objective. Other secondary objectives (Section 1.1) include examining the effect of 
ZD6474 on, (i) plasma biomarkers of angiogenesis such as VEGF, (ii),endothelial progenitor 
cells and circulating endothelial cells, (iii) time to progression (defined as the time from the start

of treatment to progression as defined by RECIST criteria, with death being treated as a censored 
event), and (iv) progression free survival (defined as time from initiation of treatment to either 
progression as defined by RECIST criteria, section 5.2.3.3, or death). The follow-up times for 
biomarker endpoints are given in Sections 3.4 and 3.5. Analyses will focus on comparing 
changes in these biomarkers on treatment from the pre-study measurement.  Longitudinal 
changes in continuous biomarkers (eg. plasma VEGF) or imaging outcomes will be analyzed 
using paired Wilcoxon-ranked sum tests (which compares measurements at a single post-
treatment time point with measurements at the pre-treatment time point) as well as with linear 
mixed models (which incorporates all follow-up times when evaluating change).  Evaluation of 
time to progression and progression free survival will be based on restaging studies performed 
approximately every 12 weeks and will be summarized using Kaplan-Meier curves. Available 
pre-treatment data on tumor size and growth rates will be used to determine if parameters such as 
TTP/stability are affected by treatment both within individual patients and in the entire treatment 
group. 
 
6.3 
ACCRUAL CEILING 
The accrual ceiling for this study is 37 patients. With an expected accrual of 10-12 patients per 
year, we expect to complete the accrual within 3-4 years.

HUMAN SUBJECTS PROTECTION 
7.1 
RATIONALE FOR SUBJECT SELECTION 
7.1.1  Research subject selection  
 Patients of all races and ethnic origins will be eligible. 
 
7.1.2 Recruitment   
This study will be recruited through internal referral, our physician referral base, and through 
Cancer Hotline information.  
  
7.2 
EVALUATION OF BENEFITS AND RISKS/DISCOMFORTS  
7.2.1 Potential benefits   
The potential benefit to a patient who enters study is a reduction in the bulk of his/her tumor, 
which may or may not have a favorable impact on symptoms, risk of metastasis and/or survival. 
 
7.2.2 Potential risks  
Potential risks include the possible occurrence of any of a range of side effects that are listed in 
the pharmaceutical section and the consent document.  The procedure for protecting against or 
minimizing risks will be to medically evaluate patients on a regular basis as described in sections 
3 and 8. 
 
 
The agent used in this trial is investigational. Experience with this agent to date suggests that this 
agent is associated with an acceptable toxicity profile. However, VHL patients may be at risk for 


Version Date: 11-16-2016 
08-C-0020 Amendment H 
Abbreviated Title: Phase II of ZD6474 in VHL 
 
Confidential  
41 
 
previously undefined or inadequately characterized complications from this agent owing to their 
unique clinical circumstances (e.g. potential risk of bleeding from cerebellar or spinal 
hemangioblastomas, unmasking or exacerbation of hypertension in patients with asymptomatic 
or occult pheochromocytomas etc.); these issues have been addressed in the consent document 
and in the appropriate sections of this protocols. The risk of delaying ‘standard of care’ therapy 
(resection of renal tumors ≥3cm) in favor of an experimental therapy is considered to be 
minimal. The UOB has extensive experience with the management of VHL-associated renal 
tumors over the past 17 years.  These tumors are slow growing tumors and often there is a 3-4 
month time period between when surgery is recommended and is carried out.  All patients 
enrolled on trial will be evaluated for a response of renal lesions following three cycles of 
therapy.  
 
7.2.3 Alternative treatments  
Patients will be apprised of other therapeutic options, both experimental and those of standard 
care (i.e., observation or surgical intervention). 
 
7.3 
RISK/BENEFIT RELATIONSHIP 
VHL patients with renal cell carcinoma or other tumors are at risk for morbidity and mortality 
from complications of local tumor growth and/or metastasis. Standard therapy for these patients 
is restricted to surgical excision, sometimes performed repeatedly. Patients enrolled on this trial 
may benefit from tumor regression which may delay or obviate the need for surgical 
intervention. Although the agent used in this trial is experimental, it has been administered safely 
in prior phase I and phase II trials and the majority of the side effects have been mild to 
moderate.  The mechanism of action of the drug suggests that the drug could potentially render 
benefit in VHL patients with clear cell renal cancer. 
 
7.4 
CONSENT AND ASSENT PROCESSES AND DOCUMENTS  
A medically responsible associate investigator or principal investigator on the trial will inform 
patients of the purpose, alternatives, treatment plan, research objectives and follow-up of this 
trial.  The patient will be provided an IRB-approved consent for review and signature and his/her 
questions will be answered.  After a decision is made to enroll into the study, a signature will be 
obtained from the patient at a subsequent visit.  A copy of the signed informed consent will be 
placed in the patient's medical record and the original held in the Protocol Office. 
 
All patients must have a signed informed consent form and an on-study (confirmation of 
eligibility) form filled out and signed by a participating investigator before entering on study. 
 
7.5 
PATIENT RECORDS AND QUALITY ASSURANCE  
Complete records must be maintained on each patient treated on the protocol.  These records will 
include primary documentation to confirm that: 
• The patient met all eligibility criteria 
• Signed informed consent was obtained prior to treatment 
• Treatment was given according to protocol.

SAFETY REPORTING REQUIREMENTS/DATA AND SAFETY MONITORING 
PLAN 
8.1 
DEFINITIONS 
8.1.1 Adverse Events 
An adverse event is defined as any reaction, side effect, or untoward event that occurs during the 
course of the clinical trial associated with the use of a drug in humans, whether or not the event 
is considered related to the treatment or clinically significant. For this study, AEs will include 
events reported by the patient, as well as clinically significant abnormal findings on physical 
examination or laboratory evaluation. A new illness, symptom, sign or clinically significant 
laboratory abnormality or worsening of a pre-existing condition or abnormality is considered an 
AE.  All AEs must be recorded on the AE case report form. 
 
All AEs, including clinically significant abnormal findings on laboratory evaluations, regardless 
of severity, will be followed until satisfactory resolution. AEs should be reported up to 30 days 
following the last dose of study drug.   
 
The development of a new cancer or tumor that is not VHL related should be regarded as an AE.  
New cancers are those that are not the primary reason for administration of study treatment and 
have been identified after inclusion of the patient into the clinical study. 
 
8.1.2 Suspected adverse reaction 
Suspected adverse reaction means any adverse event for which there is a reasonable possibility 
that the drug caused the adverse event. For the purposes of IND safety reporting, ‘reasonable 
possibility’ means there is evidence to suggest a causal relationship between the drug and the 
adverse event. A suspected adverse reaction implies a lesser degree of certainty about causality 
than adverse reaction, which means any adverse event caused by a drug. 
 
8.1.3 Unexpected adverse reaction 
An adverse event or suspected adverse reaction is considered “unexpected” if it is not listed in 
the investigator brochure or is not listed at the specificity or severity that has been observed; or, 
if an investigator brochure is not required or available, is not consistent with the risk information 
described in the general investigational plan or elsewhere in the current application. 
"Unexpected”, also refers to adverse events or suspected adverse reactions that are mentioned in 
the investigator brochure as occurring with a class of drugs or as anticipated from the 
pharmacological properties of the drug, but are not specifically mentioned as occurring with the 
particular drug under investigation. 
 
8.1.4 Serious  
An Unanticipated Problem or Protocol Deviation is serious if it meets the definition of a Serious 
Adverse Event or if it compromises the safety, welfare or rights of subjects or others.

Confidential  
43 
 
8.1.5 Serious Adverse Event 
 
An adverse event or suspected adverse reaction is considered serious if in the view of the 
investigator or the sponsor, it results in any of the following: 
• 
Death, 
• 
A life-threatening adverse drug experience 
• 
Inpatient hospitalization or prolongation of existing hospitalization 
• 
Persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• 
A congenital anomaly/birth defect. 
• 
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered a serious adverse drug experience when, based upon 
appropriate medical judgment, they may jeopardize the patient or subject and may require 
medical or surgical intervention to prevent one of the outcomes listed in this definition. 
 
8.1.6 Disability 
A substantial disruption of a person’s ability to conduct normal life functions. 
 
8.1.7 Life-threatening adverse drug experience 
Any adverse event or suspected adverse reaction that places the patient or subject, in the view of 
the investigator or sponsor, at immediate risk of death from the reaction as it occurred, i.e., it 
does not include a reaction that had it occurred in a more severe form, might have caused death. 
 
8.1.8 Protocol Deviation (NIH Definition) 
Any change, divergence, or departure from the IRB-approved research protocol.   
 
8.1.9 Non-compliance (NIH Definition) 
The failure to comply with applicable NIH Human Research Protections Program (HRPP) 
policies, IRB requirements, or regulatory requirements for the protection of human research 
subjects. 
 
8.1.10 Unanticipated Problem 
Any incident, experience, or outcome that: 
•  Is unexpected in terms of nature, severity, or frequency in relation to  
(a) the research risks that are described in the IRB-approved research protocol and 
informed consent document; Investigator’s Brochure or other study documents, and 
(b) the characteristics of the subject population being studied; AND 
• Is related or possibly related to participation in the research; AND

• Suggests that the research places subjects or others at a greater risk of harm (including 
physical, psychological, economic, or social harm) than was previously known or 
recognized. 
8.1.11 Relatedness of Adverse Event to an Intervention 
The best estimate of the PI at the time of reporting of the causal relationship between an 
experimental intervention and an adverse event; the degree of certainty about causality is graded 
as follows: 
 
Unrelated:  
Adverse event is clearly due to extraneous causes (e.g., underlying disease, environment) 
Unlikely (must have 2):  
Adverse event:

The NYHA classification system relates symptoms to everyday activities and the patient’s 
quality of life. 
 
Class 
Symptoms 
Class I (Mild) 
No limitation of physical activity.  Ordinary physical activity does not 
cause undue fatigue, palpitation, or dyspnea (shortness of breath). 
Class II (Mild) 
Slight limitation of physical activity.  Comfortable at rest, but ordinary 
physical activity results in fatigue, palpitation, or dyspnea. 
Class III (Moderate) 
Marked limitation of physical activity.  Comfortable at rest, but less 
than ordinary activity causes fatigue, palpitation, or dyspnea. 
Class IV (Severe) 
Unable to carry out any physical activity without discomfort.  
Symptoms of cardiac insufficiency at rest.  If any physical activity is 
undertaken, discomfort is increased.

12.3 APPENDIX C:  MEDICATIONS KNOWN TO PROLONG THE QT INTERVAL AND/OR INDUCE 
TORSADES DE POINTES (TDP) (UPDATED 19 AUGUST 2011) 
 
It has been recognized for a number of years that certain prescription medications can prolong 
the QT/QTc interval and cause a form of acquired Long QT syndrome, known as drug induced 
LQTS.  The drugs that prolong the QT interval and/or have a risk of inducing Torsade de Pointes 
(TdP) are listed below.  We have divided these into two groups based on their known or 
perceived risk of causing TdP: 
Group 1. Drugs that are generally accepted by authorities to have a risk of causing Torsades de 
Pointes 
− 
Concomitant use of these drugs is not allowed during the study or within 2 weeks of 
study entry (at least four weeks for levomethadyl).  These drugs should also be 
avoided for up to 4 weeks following discontinuation of study treatment:

INTRODUCTION 
 
We invite you to take part in a research study at the National Institutes of Health (NIH). 
 
First, we want you to know that: 
 
Taking part in NIH research is entirely voluntary. 
 
 
You may choose not to take part, or you may withdraw from the study at any time.  In either case, you will not 
lose any benefits to which you are otherwise entitled.  However, to receive care at the NIH, you must be taking 
part in a study or be under evaluation for study participation. 
 
 
You may receive no benefit from taking part.  The research may give us knowledge that may help people in the 
future. 
 
Second, some people have personal, religious or ethical beliefs that may limit the kinds of medical or research treatments 
they would want to receive (such as blood transfusions).  If you have such beliefs, please discuss them with your NIH 
doctors or research team before you agree to the study. 
 
Now we will describe this research study.  Before you decide to take part, please take as much time as you need to ask 
any questions and discuss this study with anyone at NIH, or with family, friends or your personal physician or other 
health professional. 
 
BACKGROUND INFORMATION 
 
What is a Research Study? 
 
A research study is a carefully supervised study that is done in humans to answer specific questions about a study drug or 
a new way of using an approved drug.  Research studies are used to determine whether study drugs or treatments are 
safe and effective in humans. 
 
You are being asked to take part in this study, also known as a clinical trial, because you have kidney cancer related to 
von Hippel-Lindau (VHL) disease.   You are invited to join this phase II study of an investigational (research) drug called 
ZD6474 (also known as vandetanib or ZACTIMA).

This document is an informed consent form that will provide you with information about this research study.  Before you 
can make a decision about whether or not to participate, you should understand what this study involves and the possible 
risks and benefits associated with this study.  If you have any questions after reading this document, please ask the study 
doctor or study nurse to explain any words or information that you do not understand.  If you agree to participate in this 
research study, you should be sure that all your questions are answered and that you understand your rights as a study 
subject.  After you sign this form you will be given a copy to keep. 
 
Why is this study being done? 
 
The purpose of this research study is to determine if the study drug ZD6474 can be used as a treatment for kidney 
tumors in people who have VHL and whether it can safely be given to patients with VHL.   ZD6474 is an experimental 
drug that is being tested as a new medication for a variety of cancers, including clear cell renal carcinoma which is the 
type of kidney cancer seen in VHL patients. ZD6474 is given once daily by mouth as a pill or liquid.  
 
Why might ZD6474 work in cancer patients?  
 
One way tumors are able to grow is by growth and development of new blood vessels which bring nutrients and oxygen 
to the tumor.  This process happens because proteins (called receptors) on the surface of cells lining blood vessels and 
cancer cells receive chemical signals that encourage the growth of new blood vessels.  Cancer cells also have other 
receptors on their surface that promote growth of cancer cells directly in response to proteins called ‘growth factors’. In 
laboratory experiments, ZD6474 works by blocking both these kinds of receptors on the surface of cancer cells or on the 
lining of blood vessels within cancers.  Blocking these receptors may cause cancer cells or the blood vessels to stop 
growing.  
 
ZD6474 has been tested in adults who have a variety of different cancers in clinical trials, but the drug has not been 
approved by the US Food and Drug Administration (FDA) as a cancer treatment.  We do not know whether ZD6474 will 
slow or stop the growth of renal cancer or whether this drug will be effective in your cancer. 
 
One of the goals of this study is to try and understand better how ZD6474 may work in humans with kidney cancer. At 
specific times throughout this study, your blood will be collected and analyzed.   These samples will be studied to look for 
special markers that may help researchers understand how ZD6474 is affecting you and/or your tumor and to develop 
tests that may be helpful in the study of kidney cancer. 
 
How many people will participate in this study? 
 
The study will initially involve 12 patients enrolled at the NIH.  If one or more people in this group have tumors that 
shrink following treatment with ZD6474, another 25 patients can enter the study. The plan is to enter up to 37 patients 
with VHL on to this study.

All eligible subjects enrolled in this study will receive the study drug ZD6474.  This study is an open label study, which 
means that both you and your doctor will know what amount of ZD6474 you are taking. 
How often will I need to visit the hospital, clinic, or doctor’s office? 
 
You will visit the NIH clinical center to help your doctors determine whether you are a suitable candidate for this study. 
This visit will involve meetings with doctors, nurses and other staff conducting this study as well as blood and urine tests 
and x-rays. Once you decide to participate in the study, you will need to come to the NIH every 2 weeks during the first 
four weeks of treatment to meet with your doctors and research nurse and also have several tests done. After the first 
four weeks, you will need to return for a visit once every four weeks. The length of each visit will depend upon the 
number of tests that are being done.  Some visits will be longer than other visits. 
 
What will I be responsible for if I participate in this study? 
 
During this study you will not be able to receive any other cancer treatments other than ZD6474.  You will be asked not 
to participate in any other clinical trials involving another experimental treatment while you are being treated in this 
study. 
Several medications (both prescription and non-prescription), ‘alternative/complementary’ or herbal preparations, dietary 
supplements, and foods such as grapefruit juice, can have undesirable interactions with ZD6474. You will not be allowed 
to take certain medications, supplements, and grapefruit juice during your participation in this study.  Your doctor or the 
study staff will review the list of drugs that you are currently taking, as well as those that you took prior to participating in 
this study. Once you are on study, please talk to your NIH doctors prior to starting any new drugs, dietary 
supplements or herbal or complementary medications. 
 
Drugs that affect the normal growth of blood vessels can delay or complicate wound healing following injury or surgical 
procedures. You should not schedule any elective surgeries while you are being treated in this study.  If you have an 
unplanned surgery, inform you doctor immediately, as you may not be able to continue study drug 
treatment. 
 
You need to keep your scheduled NIH visits and follow the instructions of your physicians and study nurse.  If you cannot 
keep one of your planned visits, call your research nurse and reschedule the visit. 
 
You will also be asked to keep a diary of when you take the medication and any side effects that you experience.  You 
will also need to bring your ZD6474 pill bottles with you to every visit for the team to count your remaining ZD6474 pills.  
You will be given a blood pressure cuff and be taught how to take your own blood pressure.  You will be asked to take 
your blood pressure at home periodically and keep a diary of the readings. If you experience any worrisome side 
effects or if your systolic blood pressure (upper or higher number) is above 150, or if your diastolic (lower 
number) is above 100 or above, you should call your doctors at the NIH or seek medical attention from 
your local doctors as soon as possible. 
 
Agents such as ZD6474, which interfere with blood vessel formation or growth may cause developmental problems in 
fetuses and breast-feeding or young children. Therefore, if you are pregnant or breast-feeding you may not participate in 
this study. If you are female and old enough to get pregnant, you will be given a pregnancy test before you are given 
ZD6474.  An appropriate and effective method of birth control (which may include abstinence) must be used by any 
person who is able to become pregnant or father a child and is receiving ZD6474.  Birth control must be continued and 
breast feeding avoided for three months after the last dose of ZD6474 is given to ensure that most of the drug is out of 
your body.  If you become or are found to be pregnant while receiving ZD6474, you must notify one of the doctors listed

on this form right away. If you become pregnant while you are taking ZD6474 you must stop taking ZD6474, and you will 
not be able to continue treatment with ZD6474. If you are a male, you should not attempt to father a child while you are 
on this drug and for at least three  months after stopping the drug. You must use an appropriate and effective method of 
birth control during this period. The effect of this drug on your ability to bear or father children after you discontinue 
treatment is unknown. 
 
WOMEN OF CHILD-BEARING POTENTIAL 
There might be unknown risks to the unborn child if you are or if you become pregnant during the study.  Due to these 
risks, you must not participate in this study if you are pregnant, or plan to become pregnant during the research study 
period, or are breast-feeding a child. 
If you are a woman of child-bearing potential: 
• 
By signing this consent form, you confirm to the best of your knowledge that you are not pregnant now and you 
do not intend to become pregnant during this study 
• 
A pregnancy test will be done to confirm that you are not pregnant before you take part in this study 
• 
You must avoid becoming pregnant and use an acceptable method of birth control during this study. 
If at any time during this study you think you might be pregnant, or later learn that you were pregnant during the study, 
you must contact the study doctor immediately for further instructions about your participation in this study and follow-
up. 
MALE Patients 
The study drug used in this study could affect your sperm and could potentially harm a child that you may father while in 
this study.  You must avoid unprotected sex with a pregnant partner (or woman of child-bearing potential not using birth 
control) or donating sperm during the study and for three months following the last dose, since the potential for problems 
with the fetus has not yet been thoroughly investigated.  Men should use a condom during the trial and for three months 
following the last dose. 
If your partner becomes pregnant, you must notify the study doctor of any outcomes of the pregnancy from the date of 
the first dose until three months after last dose of ZD6474. 
 
TYPES OF TESTS OR PROCEDURES INVOLVED WITH THIS STUDY  
 
Once you meet with your doctors and research team at the NIH and undergo the necessary tests to determine if you are 
a suitable candidate for this study, you can decide whether you want to participate. If you choose to take part, then you 
will be started on ZD6474.  This drug is given by mouth once every day (treatment periods are divided arbitrarily into 
cycles-a cycle of ZD6474 is 28 days). You will be instructed about how to take ZD6474.  
 
During the 1st cycle, you will need to return to the NIH every 2 weeks on the same day of the week as of your first dose 
of ZD6474.  If you stay on the drug after the 1st cycle, you will return to the NIH every four weeks. 
 
At clinic visits during your participation in this study you will have the following tests and procedures.  They are part of 
regular cancer care.

● 
Vital signs (pulse rate, respiration rate, oral temperature, and blood pressure), weight, and performance status 
will be taken at each study visit. 
● 
Blood will be collected for chemistry, hematology, and other labs to determine if the study drug is causing any ill 
effects on your body.  These samples will be taken at each study visit.  About 3-5 teaspoons will be taken each 
time you visit the doctor for this study.   
● 
If you are a female and able to get pregnant, a pregnancy test will be done within the week before starting the 
study and once every four weeks during treatment before your continue with each new cycle.  
The following tests and procedures will also be done. Even though they are part of regular cancer care, it is possible they 
are being done more often because you are in this study.   
● 
You will have imaging scans (CT or MRI) done approximately every 12 weeks to assess the size of your tumors 
(or sooner if your doctor feels it is necessary) 
● 
You will have urine collected during the 1st week of every cycle. 
● 
You will have an electrocardiogram (EKG) and routine blood work done every week during the 1st two cycles.  If 
you stay on the drug longer, then EKGs will be performed every four weeks.  This means that some of the EKGs 
and blood work will need to be performed locally near your home and the results sent to the NIH.    
The following research studies will be done to see how ZD6474 is affecting your body. 
● 
Your blood will be taken before and after the ZD6474 dose at weeks 1 and 3 of the 1st cycle, and every four 
weeks after that, as well as the end of treatment to look for special markers affecting you and/or your tumor that 
may be helpful in the study of kidney cancer.  About 8 tablespoons will be collected for this portion of the 
research tests.

Can I stop being in the study? 
 
Yes.  You can decide to stop at any time.  Tell the study doctor if you are thinking about stopping or decide to stop.  He 
or she will tell you how to stop safely.  
 
It is important to tell the study doctor if you are thinking about stopping so any risks from ZD6474 can be evaluated by 
your doctor.  Another reason to tell your doctor that you are thinking about stopping is to discuss what follow up care and 
testing could be most helpful for you. 
 
The study doctor may stop you from taking part in this study at any time if he/she believes it is in your best interest; if 
you do not follow the study rules; or if the study is stopped. 
 
When am I finished with the Study? 
 
You may continue to receive ZD6474 treatment in this study until: 
• 
your tumors get larger, or 
• 
your doctor feels you are not benefiting from ZD6474, or  
• 
you experience intolerable side effects or side effects which make it unsafe for you to continue, or   
• 
the doctors taking care of you feel it is not in your best interest to continue, or  
• 
you choose to withdraw from this study, or 
• 
you are unable to keep scheduled medical appointments or take the study medication as instructed, or  
• 
a better therapy becomes available, or 
• 
you are a female and become pregnant, or  
• 
the drug is no longer available or the study closes 
 
Safety Follow-up Visit/End of study visit: 
 
If you come off of the treatment for any of the reasons listed above, we would like to continue to check up on you 
periodically through phone calls to you, your family or your home doctor’s office. 
 
If you experience a side effect or abnormal laboratory results, your study doctor may ask that you come back for 
additional visits until the side effect resolves  
 
SIDE EFFECTS OR RISKS FROM BEING IN THE STUDY 
 
More than 5000 patients with different types of tumors have been treated with ZD6474. A variety of side effects have 
been seen in patients receiving ZD6474 and are described below. In addition to the possible side effects listed below, 
there is always the risk of uncommon or unexpected side effects that you may experience when taking ZD6474.  Your 
doctor will closely monitor you throughout this study and discuss with you any questions regarding risks, discomforts and 
side effects. 
 
The administration of any drug involves a general risk of allergic drug reactions.  The symptoms that may occur include 
headache, rashes/hives, flushing, swollen skin, breathlessness, dizziness, nausea, and sometimes vomiting.  In rare 
cases, life-threatening reactions may develop, including choking attacks, dangerously low blood pressure and loss of 
consciousness, which will require immediate treatment.

To our knowledge, patients with VHL have not received this drug outside this trial and hence it is not known whether 
these patients may develop additional or more severe side effects than non-VHL patients. 
 
If at any time you have any questions about side effects or if you think you have a side effect or a change in your health 
condition, it is important that you speak to your study physician.   
 
Known side effects in patients receiving ZD6474 
 
All drugs have potential side effects.  One of the purposes of this study is to learn about the possible side effects of 
ZD6474.  Many drug-related side effects will go away shortly after stopping the drug, but in some cases side effects may 
be serious, long, lasting, or permanent.  During your study treatment and for at least 30 days after your last dose of 
ZD6474, it will be very important for you to report any possible side effects or symptoms that you develop to your study 
doctor. 
 
Everyone taking part in the study will be watched carefully for any side effects.  However, doctors don’t know all the side 
effects that may occur.  Side effects may be mild or very serious. Your health care team may give you medicines to help 
lessen some side effects. It may become necessary to temporarily or permanently discontinue ZD6474 or alter the dose of 
the drugs due to side effects you experience. 
 
Patients in clinical studies using ZD6474 have reported the following symptoms and side effects related to ZD6474:  
 
Likely / Common (> 10%): 
• skin rashes 
• nausea  
• loss of appetite 
• weight loss 
• diarrhea 
• constipation 
• high blood pressure 
• changes on the EKG without any symptoms  
• feeling tired 
• headache 
• dizziness 
• depression and anxiety

• Formation of clots, such as in the lung or in the legs 
• Bleeding, from tumors or non tumor sites 
• Bleeding in or around the brain 
• Lack of blood flow to heart (heart attack), brain (stroke), eye (blindness),legs, or bowel 
• Serious or life threatening complications from rashes 
• Lung inflammation and stiffening, infections or fluid accumulation around the lungs 
• Blockage or penetration of the bowel or gall bladder duct 
• Kidney failure 
• Problems with wound healing and spreading bacterial infection of the deeper layers of skin and soft tissu 
• Heart Failure, which is the weakening of the heart's ability to pump blood has also been reported and may be related 
to vandetanib. We will be monitoring your heart function with an ekg. If significant changes occur, we may need to 
stop therapy. 
• Seizures, some patients have had seizures while taking vandetanib, and in one case a patient with seizures also 
had swelling in the brain that was found on an MRI scan, which got better after vandetanib was stopped. If you 
develop seizures, dizziness, headache, changes in your vision, or confusion, you should let your study doctor 
know as soon as possible. These may be symptoms of reversible posterior leukoencephalopathy 
syndrome (RPLS). 
 
In addition, a number of other side effects have been reported in clinical trials using ZD6474 alone, in combination with 
other chemotherapy agents or radiation. It is unclear whether these side effects are related to ZD6474, or are caused by 
other factors (such as chemotherapy or radiation). These side effects include: 
• Infections, including life-threatening bacterial infections 
• Facial nerve palsies or reversible confusion, seizures and swelling in the brain 
• Brief loss of consciousness

• Weakening of the heart muscle or inability of the heart to pump efficiently 
• Severe breathing problems or lung failure 
• Development of an abnormal pathway between the esophagus (tube connecting the throat to the stomach) and 
trachea (windpipe) or surrounding structures 
• Development of an abnormal communication between the intestines and surrounding structures, including the urinary 
bladder 
 
AstraZeneca is monitoring patients receiving vandetanib.  You and your study doctor will be told if we have further 
information about vandetanib that might be relevant to your willingness to continue to take part in the study. 
 
Many side effects, including skin rashes, diarrhea, high blood pressure and EKG changes are often reversible and can 
usually be improved by reducing the dose of ZD6474.  If you develop a skin rash, creams and oral medications can be 
given.  If you develop diarrhea related to the ZD6474, medications to stop the diarrhea can be used. 
 
Your skin will be more sensitive to the sun, and you should minimize your exposure to the sun. This may be done 
by reducing the time you are out in the sun, using a hat and clothing to cover most of your body and applying 
sunscreens with an SPF 45 or higher any time you are outdoors. It is recommended that you take preventative 
action to prevent the rash from occurring while receiving study medication and for 3 to 4 weeks after stopping 
treatment by using the afore mentioned guidelines. 
 
Also, you must notify the study team when the first sign of a rash occurs so that the appropriate steps can be taken in an 
attempt to prevent the rash from becoming severe.   
 
Your eyes may be more dry and changes to your corneas may occur.  In order to prevent corneal ulcers and other eye 
problems, do not wear contact lenses while taking ZD6474. 
 
Your blood pressure will be monitored carefully on the study and, if found to be elevated, medications to lower your blood 
pressure can be used.  If you have uncontrolled high blood pressure, this elevated pressure can cause damage to other 
organs including the heart, kidneys, or brain.  Having uncontrolled blood pressure increases the risk of heart attack and 
stroke in adults.  High blood pressure may be associated with no symptoms; however, dizziness, headache or nose bleed 
can occur in patients with high blood pressure. You will be asked to record your blood pressure at least once a day. If 
your systolic blood pressure (upper or higher number) is above 150, or if your diastolic (lower number) is 
above 100 or above, please call your doctors at the NIH or seek medical attention from your local doctors 
as soon as possible. 
 
We will monitor your heart function closely by performing ECG/EKGs periodically to look at your heart rate and rhythm. 
This procedure is associated with minimal discomfort. Abnormalities on the EKG have been reported in patients taking 
ZD6474 on other trials. Some of these abnormalities can have serious or life-threatening consequences if appropriate 
action is not taken (usually stopping or reducing the dose of ZD6474 and/or ensuring that blood electrolyte levels are 
normal). However, as a result of close monitoring and timely intervention, no serious problems or symptoms related to 
these EKG abnormalities have been reported so far. 
 
AstraZeneca has observed changes in ECGs in some patients being treated with vandetanib. These changes in the 
ECG may be drug-related and usually occur without symptoms; accordingly, frequent safety follow-up visits have 
been built into all studies. Similar changes in the ECGs of patients receiving other medications have led to heart 
rhythm changes, some of which have been life threatening. However, it is estimated that between 0.1 to

1% of patients receiving vandetanib 300 mg have developed heart rhythm changes linked to life-
threatening arrhythmia called Torsades de Pointes. Torsades de Pointes has been associated with 
sudden death. If any such changes are noted on your ECGs, you may need to attend additional visits for further 
safety assessments.  
 
The risk of developing changes in the ECG and serious heart rhythm changes will be greater if you have diarrhea, 
vomiting, high fever, faintness or dizzy spells, or are unable to maintain a normal diet.  You should report any of 
these symptoms to your doctor immediately.  You should review your medications and diet with your doctor at 
each visit while you are continuing to receive study medication. 
 
These changes in the ECG usually occur without you being able to sense it happening, so frequent follow-up has been 
built into the study.  You may be able to sense some changes in the heart rhythm such as rapid or irregular heart 
beating, dizziness, light-headedness, chest discomfort, shortness of breath, and losing consciousness.  These or other 
new symptoms or possible side effects should be reported immediately to your doctor. 
 
A rare side effect of anti-blood vessel agents such as ZD6474 is a risk of bleeding, which can sometimes occur at the site 
of or from tumors.  Although patients taking ZD6474 on other trials have experienced bleeding (including one case of 
bleeding into the brain) it is not clear how frequently bleeding occurs or whether these are related to ZD6474. Other 
drugs (including some drugs that are approved by the FDA for treating kidney cancer) have been associated with 
bleeding, which, in some cases have been life-threatening or fatal. Since patients with VHL have tumors at multiple 
locations within the body, bleeding from tumors can have serious or life-threatening consequences, especially if it involves 
hemangioblastomas in areas such as the brain, the spinal cord or angiomas in the eye. 
 
Drugs that affect the normal growth of blood vessels can delay or complicate wound healing following injury or surgical 
procedures. You should not schedule any elective surgeries while you are being treated in this study.  If you have an 
unplanned surgery, inform you doctor immediately, as you may not be able to continue study drug treatment. 
 
The long-term side effects of ZD6474 are not known.  It is possible that there may be temporary or permanent side 
effects of ZD6474 that have not yet been identified. 
 
The effects of ZD6474 on the human fetus or nursing infant are not known. ZD6474 is harmful to fetal development in 
animals. 
 
Known side effects of the procedures that will be done in this research study 
 
Blood Collection 
 
The risks associated with blood collection include discomfort, pain, bleeding, bruising, redness, swelling and/or bruising 
where the blood is drawn from your arm.  Fainting and infection are rare, but can happen with blood collection.  By 
signing this consent form, you are authorizing NIH investigators to use your blood samples for those procedures identified 
in the study protocol. 
 
ECG 
 
A recording of the normal electrical activity of your heart is taken by placing electrodes (pieces of metal attached to 
wires) on the skin of your chest, arms, and legs.  There is minimal discomfort and there are no risks.

Echo 
 
An echocardiogram is an ultrasound of your heart.  An ultrasound is an image made from sound waves.  There is no 
discomfort and there are no risks. 
 
Imaging studies 
 
You will have a CT scan or MRI to measure the size of your cancer(s) before starting the treatment and some or all of 
these scans will be used to periodically monitor the change in the size of your cancer(s) on ZD6474.  These scans are 
common standard imaging tests used in the diagnosis and monitoring of many diseases.  Although these tests have been 
in use for many years, their potential long term effects on the body are still being learned. 
 
MRI Scan  
 
There are no known harmful effects from the strong magnetic field used for MRI. However, the magnet is so powerful 
that it may affect pacemakers, artificial limbs, and other medical devices that contain iron.  You should tell the study staff 
about any metal devices that you may have in your body.  
 
Iron pigments in tattooed eyeliner can cause eye irritation. 
There is slight risk of developing an allergic reaction if contrast material is used during the MRI scan. However, most 
reactions are mild and can be controlled using medication. 
 
The MRI scan is performed in a long narrow tube.  You may experience discomfort related to lying still in an enclosed 
space for a prolonged period of time.  The study staff prior to performing the procedure will provide additional 
instructions to you.  If this occurs, cool air can be blown over you by a fan if desired or your doctor can order a medicine 
to help you relax during this scan.  Keeping the room well lit can also reduce this claustrophobic feeling.  
 
CT Scan  
 
If a contrast agent (the special dye) is given with the scan there is a small risk of having a reaction to the contrast.  
These reactions can include nausea, pain in the vein where the contrast was given, headache, a metallic or bitter taste in 
the mouth, and a warm or flushing feeling that lasts from 1-3 minutes.  Rarely, these symptoms may require treatment.  
In very rare cases, people have had more severe allergic reactions that result in shortness of breath, wheezing, or 
lowering of the blood pressure.  If you have had a reaction in the past, be sure to tell your doctor or nurse about it.   
 
You will be exposed to a limited and medically acceptable dose of radiation during the procedure.  There is always a slight 
risk from being exposed to any radiation, including the low levels of X-rays used for a CT scan. 
 
The radiation dose you receive, if your scans include the use of X-rays or radioactive chemicals, is within the safe limits 
defined by the NIH Radiation Safety Guidelines, and is considered essential for your medical care. 
 
Delay in surgical resection of kidney tumor(s) 
 
Von Hippel-Lindau patients with kidney tumors that have reached a certain size (usually around 3cm) would normally be 
advised to undergo surgery to remove them. Surgical removal of tumors is done to lessen the risk of spread to other

organs.  Removing your kidney tumors does not mean that your cancer has been ‘cured’.  Even if you have surgery to 
remove your kidney tumor(s), it is possible that you will develop new tumors and may need surgery again in the future. 
 
Your tumors may or may not be large enough to require surgical resection in the near future. If they are large enough to 
require surgery, a delay in surgery may result if you choose to participate in this study and your tumors do not decrease 
in size with ZD6474.  We feel that delaying surgery for approximately 12 weeks is unlikely to greatly increase the risk of 
tumor spread from your kidneys. After 12 weeks, depending on the effect of ZD6474 on your tumors, a decision will be 
made about whether it is safe to delay surgery any further. If any of your kidney tumors should be very large, we will 
advise surgery at the earliest possible time and will exclude you from the current study. 
 
Potential Benefits of Participation 
 
You are being offered this experimental drug (ZD6474) because it may be of benefit to you in treating your VHL disease.  
One potential benefit may be shrinkage of your tumors that would enable you to delay or avoid surgery.  Another possible 
benefit might be changes to the tumor environment (such as decreased blood supply) that may make surgical removal of 
your tumor(s) easier.  However, there is no guarantee that this drug is of benefit to humans or that you will benefit from 
taking part in the study.  The drug you receive may even be harmful to you.  
 
Individual patients will not have a benefit from taking part in the investigational procedures such as research done on 
your blood samples or tumor tissue.  However, future patients may benefit from what is learned.   
Your participation in this study is voluntary.   
 
Potential Benefits to Society 
 
The knowledge gained from this study may benefit others.  Your participation may help to determine if ZD6474 treatment 
can be safely and effectively given to other patients with VHL. 
 
Alternative to Participation/ Alternative Approaches or Treatments 
 
You may choose not to participate in this study.  Other treatment options may be available to you.  Your doctor is very 
willing to discuss the benefits and side effects of other ways to treat your tumors including the option of surgical resection 
of your tumor(s), treatment of your symptoms only, and other investigational protocols that may be available for your 
condition. 
 
Your other choices may include: 
 
• 
Getting care for your cancer without being in a study 
 
• 
Taking part in another study 
 
• 
Surgical removal of your tumor(s) 
 
• 
Getting no treatment

CONFIDENTIALITY OF MEDICAL INFORMATION 
 
Will my medical information be kept private? 
 
We will do our best to make sure that the personal information in your medical record will be kept private.  However, we 
cannot guarantee total privacy.  Your personal information may be given out if required by law.  If information from this 
study is published or presented at scientific meetings, your name and other personal information will not be used.  
 
All patients will be given a number upon signing this informed consent form.  The number will be used throughout the 
study as your main identifier on study documents that will be sent to AstraZeneca (the drug company that provides the 
drug used in this trial).  Every effort will be made to ensure that documents that contain your personal information will be 
crossed out and replaced with your subject identification number if sent to AstraZeneca. 
 
All research samples will be labeled with a unique bar code number.  Only the investigator and designated study site staff 
(i.e. staff at the NIH) will have the key to link the bar-coded samples to the subject to which they correspond. 
 
Neither your results nor your samples will be identified with your name in communications with AstraZeneca.  A number 
will be used in all regulatory documentation related to this study.  It is a requirement that your involvement in this study 
be noted in your medical records. 
 
Since research studies on samples you provide are not expected to benefit you directly or to change your treatment 
course, these results will not be placed in your medical record and will not be made available to you, members of your 
family, your personal physician, or other third parties. 
 
The confidentiality of your medical records will be maintained to the extent permitted by the applicable laws.  If results of 
the trial are published, your identity will remain confidential.  Using your subject number only, the results and other 
information from the study may be submitted to regulatory agencies in countries where the study drug may be submitted 
for approval. 
 
WHAT WILL BE DONE WITH MY BLOOD AND TUMOR SAMPLES? 
 
Consent for Tissue/ Blood (specimen) Banking 
 
During the course of the study, several research studies will be performed on your blood and tissue samples. These 
studies will be done to try to better understand: 
• 
how the drug is handled by your body (i.e, how it is absorbed and broken down) 
• 
what effects the drug has on your body 
• 
whether the drug affects any components of the mechanism that is responsible for formation of new blood 
vessels in or growth of tumors
