Clinical trial NCT02315430
Conditions: Fallopian Tube Clear Cell Adenocarcinoma Ovarian Clear Cell Adenocarcinoma Recurrent Fallopian Tube Carcinoma Recurrent Ovarian Carcinoma Recurrent Primary Peritoneal Carcinoma
Sponsor: National Cancer Institute (NCI)
Start date: 2015-04-01; Completion date: 2019-02-09
Enrollment: 13 participants; Allocation: NA; Intervention model: SINGLE_GROUP

Brief summary:
This phase II trial studies how well cabozantinib-s-malate works in treating patients with ovarian, fallopian tube, or primary peritoneal cavity cancer that has come back or is growing, spreading, or getting worse. Cabozantinib-s-malate may stop the growth of tumor cells by blocking the growth of new blood vessels necessary for tumor growth and also by blocking some of the enzymes needed for cell growth.

Detailed description:
PRIMARY OBJECTIVES:

I. To evaluate the anti-tumor activity of cabozantinib (XL184) (cabozantinib-s-malate) in women with persistent or recurrent clear cell ovarian cancer, based on the proportion of patients who survive progression-free for at least 6 months and the proportion who have objective tumor response (complete or partial).

SECONDARY OBJECTIVES:

I. To determine the nature, frequency and maximum degree of toxicity as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v)4 for cabozantinib (XL184).

II. To determine the progression free survival (PFS) and overall survival (OS) for patients with persistent or recurrent clear cell ovarian cancer treated with cabozantinib (XL184).

TERTIARY OBJECTIVES:

I. To examine the expression of phosphatase and tensin homolog gene (PTEN), phosphorylated v-akt murine thymoma viral oncogene homolog 1 (pAKT), cyclin E, and met proto-oncogene (MET) in formalin-fixed, paraffin-embedded tumor.

II. To examine MET amplification (fluorescence in situ hybridization) in tumor specimens and the relationship to response.

OUTLINE:

Patients receive cabozantinib-s-malate orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

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

Arms: arm 1: Patients receive cabozantinib-s-malate PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Interventions: intervention 1: Cabozantinib S-malate intervention 2: Laboratory Biomarker Analysis
Intervention descriptions: intervention 1: Given PO intervention 2: Optional correlative studies

2. BACKGROUND 
 
2.1 
Clinical Research Background 
Ovarian cancer is the most lethal gynecologic malignancy (Siegel, 2012)  In 2014 we 
could expect 21,980 cases of ovarian cancer and 14,270 deaths. Standard therapy for 
ovarian cancer includes surgical debulking of any primary tumor followed by adjuvant 
chemotherapy with carboplatin and paclitaxel when needed. Patients with advanced stage 
disease have a 5-year survival of only 29% (Siegel, 2012), (Christensen, 2005) Epithelial 
ovarian cancer is considered a chemoresponsive tumor with response rates of 80% to 
standard therapy of platinum and a taxane (Siegel, 2012), (Bhoola, 2006), (Cannistra, 
2004), (Piccart, 2003), (Tummala, 2005) Unfortunately most patients develop recurrent 
disease, chemoresistant disease and the patients are essentially incurable.  In the United 
States, ovarian clear cell carcinoma (OCCC) accounts for approximately 4-9.5% of 
ovarian tumors, whereas in Japan, the rate is upwards of 15-25%. 
  
Age, performance status, tumor histology, and residual disease volume have been found 
to be statistically significant prognostic factors for advanced stage epithelial ovarian 
cancer in multivariate analyses (Winter, 2007) Clear-cell histology has been generally 
accepted as an unfavorable histology. Clear-cell epithelial ovarian carcinomas are 
associated with a worse PFS and OS when compared with serous histology. In a study of 
similarly treated advanced epithelial ovarian cancer patients clear cell tumors had a 
decreased median OS of 24 months compared to 45 and 56 months for serous and 
endometrioid histologies, respectively. 
 
Expression profiling of epithelial ovarian cancer of varying histologies has afforded the 
elucidation of genes which contribute to the biological and clinical features seen in the 
four major histological types of ovarian carcinoma (Bonome, 2008), (Zorn, 2005) When 
clear cell ovarian cancer was compared with non–clear cell ovarian cancer (serous and 
endometrioid ovarian cancer grouped together), 171 differentially expressed genes were 
identified (Bonome, 2008)  For clear cell tumors in general; there is a small set of 
differentially expressed genes common to tumors from all organs, ovary, endometrium 
and kidney. These genes include TFPI2 (tissue factor pathway inhibitor), ANXA4 
(Annexin), UGT1A1 (UDP glycosyltransferase1family, polypeptideA1), FXYD2 (FXYD 
domain containing ion transport regulator 2), GLRX (Glutaredoxin), KIAA1922 
(KIAA1922 protein), MAP3K5 (Mitogen-activated protein kinase kinase kinase 5), 
CXADR (Coxsackie virus and adenovirus receptor), and RFX5 (Regulatory factor X, 5). 
(Zorn, 2005) This over expression of certain types of genes in the clear cell histotype 
provides insights into their disproportionately poor prognosis relative to other types of 
ovarian cancer. Two of these genes have intriguing associations with chemotherapy 
response: ANXA4 has been associated with paclitaxel resistance, whereas UGT1A1 
detoxifies the active metabolite of irinotecan (Pal, 2012), (Gibney, 2013) The sum total 
clinical and biological effect of these genes is to increase anti-apoptotic signals 
(ASK1/GLRX), inhibit cellular proliferation (TFP12), and increase resistance to 
chemotherapeutic agents (ANXA4 and UGT1A1), which is consistent with the slow

growth and relative chemoresistance of clear cell tumors.  
 
MET. MET has a number of purported roles in the pathogenesis of RCC. Over a 
decade ago, germ line and somatic mutations were identified in the tyrosine kinase 
domain of MET in patients with papillary RCC 8. MET plays a critical role in clear cell 
RCC. Inactivation of VHL may actually cause constitutive activation of the moiety, and 
VHL null RCC cell lines appear to be exquisitely sensitive to MET shRNA. (Zorn, 2005) 
c-Met protein expression was determined by automated quantitative analysis (AQUA) on 
a Tissue microarray (TMA) data incorporating 330 unique RCC specimens c-Met 
expression and selective inhibition with SU11274 and ARQ 197 were also studied in 
clear cell RCC cell lines. (Pal, 2012) Higher c-Met expression was detected in all RCC 
subtypes than in the adjacent normal renal tissue (P < 0.0001). Expression was highest in 
papillary and sarcomatoid subtypes, and high-grade and stage tumors. Higher c-Met 
expression correlated with worse disease-specific survival [risk ratio = 1.36; 95% 
confidence interval (CI) 1.08-1.74; P = 0.0091] and was an independent predictor of 
survival, maintained in clear cell subset analyses. c-Met protein was activated in all cell 
lines, and proliferation (and colony formation) was blocked by SU11274 and ARQ 197. 
They concluded that c-Met is associated with poor pathologic features and prognosis in 
RCC. Additionally, c-Met inhibition demonstrates in vitro activity against clear cell RCC.  
Deregulation of the c-Met-HGF/SF (hepatocyte growth factor/scatter factor) signaling 
axis has been identified as a contributing factor to tumorigenesis and tumor progression 
in numerous cancers. (Zillhardt, 2011) This pathway has also been shown to show a 
critical role in the pathogenesis of ovarian cancer (Gibney, 2013), (Zillhardt, 2011). An 
examination of approximately 170 candidate genes/regions in a multistage analysis based 
initially on 312 Mayo Clinic ovarian cancer cases revealed the strongest initial mortality 
association was associated with HGF (hepatocyte growth factor). (Zillhardt, 2011) 
Analysis of TCGA data revealed consistent findings and suggested a potential genotype 
correlation with reduced HGF mRNA levels. In analysis of the Mayo Clinic TMAs, 
protein levels of phospho-MET were associated with reduced mortality. They concluded 
that although HGF signaling is critical to migration, invasion, and apoptosis, it is unlikely 
that HGF genetic variation plays a major role in ovarian cancer mortality.  
Perturbation of the c-Met-HGF/SF pathway in ovarian cancer carcinogenesis has been 
demonstrated in the laboratory. Evaluation of a multikinase inhibitor of c-Met and 
vascular endothelial growth factor receptor-2 (foretinib, GSK1363089) was performed in 
a genetic mouse model. In the genetic mouse model, treatment with foretinib prevented 
the progression of primary ovarian tumors to invasive adenocarcinoma. (Gibney, 2013) 
Invasion through the basement membrane was completely blocked in treated mice, 
whereas in control mice, invasive tumors entirely replaced the normal ovary. In two 
xenograft mouse models using human ovarian cancer cell lines, the inhibitor reduced 
overall tumor burden. The mechanism of inhibition by foretinib involved (a) inhibition of 
c-Met activation and downstream signaling, (b) reduction of ovarian cancer cell adhesion, 
(c) a block in migration and invasion, (d) reduced proliferation mediated by a G2–M cell-
cycle arrest, and (e) induction of anoikis. (Gibney, 2013) This study shows that a 
multikinase inhibitor of c-Met and VEGF-2 blocks tumorigenesis and reduces invasive 
tumor growth in different models of ovarian cancer by affecting several critical tumor

functions. These observations provide a rationale for the further clinical development of 
c-Met inhibitors for the treatment of ovarian cancer.  
An additional study demonstrated that, among ovarian carcinomas, amplification of the 
MET gene and overexpression of MET specifically and commonly occur in clear-cell 
adenocarcinoma histology12,1314. Low-level (≥3 MET copies in ≥10% and ≥4 MET copies 
in 10-40% of tumor cells) gain of MET was detected in 4 (40%) of the 10 atypical 
endometrioses and 1 of the 2 borderline CCAFs. Moreover, high-level (≥4 MET copies in 
≥40% of tumor cells) gain of MET were detected in five (50%) of the atypical 
endometrioses. In 4 (31%) of the 13 cases enrolled, intratumoral heterogeneity for MET 
gain was documented in invasive carcinoma components, wherein all the relatively 
differentiated carcinoma components showed low-level gain of MET and all the 
corresponding poorly differentiated carcinomas showed high-level gain. The overall 
incidence of MET overexpression gradually increased from the ovarian clear cell 
carcinoma precursors of non-atypical form (0%), through those of atypical form (67%) 
and the relatively differentiated carcinoma components (92%), to the poorly 
differentiated carcinoma components (100%). These results suggest that accumulative 
MET gene copy number alterations causing MET overexpression are associated with 
higher tumor grade ovarian clear cell carcinomas and might drive the development and 
progression of the MET amplification-positive ovarian clear-cell adenocarcinoma. 
(Goode, 2011), (Yamamoto, 2012) Also, in patients with early stage (stage I and 2) clear 
cell ovarian cancer, Met gene amplification is associated with worse survival (Yamashita 
et al. PLoS One. 2013; 8(3):e57724). Overexpression of the IL6-STAT3-HIF pathway 
commonly occurs in ovarian clear cell cancer and this pathway is known to activate MET 
promoter which contains hypoxia inducible factor-1 (HIF-1) binding sites and thus 
upregulate MET expression (Anglesio, 2011) (Anglesio et al. Clin Cancer Res. 2011 Apr 
15; 17(8):2538-48).  IL6 levels are also elevated in women with endometriosis. Therefore 
deregulation of IL6 expression seems to be an early event in the development of ovarian 
clear cell carcinoma. IL6 signals via STAT3 and activates expression of downstream 
genes including PTHLH and HIF1A. Strong expression of activated pSTAT3 in tumors 
and cell lines and nuclear HIF1A in TMA, were observed and consistent with autocrine 
activation of the pathway. Finally, in a phase II randomized discontinuation trial of 
cabozantinib in advanced ovarian cancer patients, there were 3 patients with clear cell 
ovarian cancer: one had a RECIST PR, one had a close to-PR response and the third had 
stable disease with decrease in her CA125 level (Buckanovich et al. ASCO 2011 
meeting, J Clin Oncol 29: 2011 (suppl; abstr 5008). Cabozantinib (NSC# 761968). 
Cabozantinib (NSC# 761968), is an orally bioavailable inhibitor of multiple receptor 
tyrosine kinases (RTKs) including c-Met and vascular endothelial growth factor receptor 
2 (VEGFR2).  
Mechanism of Action 
Cabozantinib is a potent inhibitor of MET and VEGFR2. Cabozantinib strongly inhibited 
several kinases that have also been implicated in tumor pathobiology, including KIT, 
RET, AXL, TIE2, and FLT3. Cabozantinib did not potently inhibit kinases such as RON, 
EGFR, IGFR1, and EphA4/B4. In cellular assays, cabozantinib inhibited phosphorylation 
of MET and VEGFR2, as well as KIT, FLT3, and AXL. (Yakes, 2011)

The dual VEGFR2/MET targeting agent, cabozantinib, has recently shown 
unprecedented activity in the setting of metastatic castration resistant prostate cancer 
(mCRPC), causing regression of metastases visualized on bone scan in 56 of 65 evaluable 
patients (86%) enrolled in a randomized, phase II study. (Smith, 2013) Patients received 
100 mg of cabozantinib daily. One hundred seventy-one men with CRPC were enrolled. 
Random assignment was halted early based on the observed activity of Cabozantinib. 
Seventy-two percent of patients had regression in soft tissue lesions, whereas 68% of 
evaluable patients had improvement on bone scan, including complete resolution in 12%. 
The objective response rate at 12 weeks was 5%, with stable disease in 75% of patients. 
Thirty-one patients with stable disease at week 12 were randomly assigned. Median PFS 
was 23.9 weeks (95% CI, 10.7 to 62.4 weeks) with Cabozantinib and 5.9 weeks (95% CI, 
5.4 to 6.6 weeks) with placebo (hazard ratio, 0.12; P < .001). Cabozantinib had clinical 
activity in men with CRPC, including reduction of soft tissue lesions, improvement in 
PFS, resolution of bone scans, and reductions in bone turnover markers, pain, and 
narcotic use (Zorn, 2005), (Smith, 2013), (Vaishampayan, 2013)  Early experiences with 
cabozantinib also indicate substantial activity in ovarian cancer and medullary thyroid 
carcinoma (Vaishampayan, 2013), (Kurzrock, 2011)_ENREF_29. Given these promising 
preliminary results, the further development plan for cabozantinib in OCCC is eagerly 
anticipated. 
 
2.2 
Cabozantinib (XL184) 
 
Cabozantinib inhibits multiple receptor tyrosine kinases (RTKs) implicated in tumor 
growth, metastasis, and angiogenesis (Investigator’s Brochure, 2011).  The primary 
targets of cabozantinib are MET (c-MET) and vascular endothelial growth factor receptor 
2 (VEGFR2); additional targets include RET, AXL, KIT, and TIE-2.  Both c-Met and 
VEGFR2 are important mediators of tumor growth and tumor angiogenesis, and in vivo 
pharmacodynamic activity of Cabozantinib against c-Met and VEGFR2 has been 
demonstrated in both preclinical and clinical studies.  
 
RTKs regulate many processes including cell growth and survival, organ morphogenesis, 
neovascularization, and tissue repair (Christensen, 2005)  Dysregulation of RTKs by 
mutation, gene rearrangement, gene amplification, and overexpression of both receptor 
and ligand have been implicated as causative factors in the development and progression 
of numerous human cancers. 
 
The RTK c-Met, encodes the high-affinity receptor for hepatocyte growth factor (HGF) 
or scatter factor (SF) (Christensen, 2005) c-Met and HGF are each required for normal 
mammalian development and have been shown to be important in cell migration, 
morphogenic differentiation, and organization of three-dimensional tubular structures 
(e.g., renal tubular cells, gland formation, etc.), as well as cell growth, angiogenesis, and 
tumor invasiveness and metastasis.  Upregulation of MET is found in a wide range of 
malignancies including thyroid, prostate, ovarian, lung, and breast cancers, and is 
associated with more aggressive and invasive phenotypes of cancer cells in vitro and 
metastases in vivo (Investigator’s Brochure, 2011). c-Met-driven metastasis may be 
exacerbated by a number of factors, including tumor hypoxia caused by selective

14 
 
inhibition of the VEGF pathway. 
 
Evidence linking c-Met and HGF as causative or progression factors in human cancers 
include:  (1) the overexpression of both receptor and ligand in neoplasms relative to 
surrounding tissues; (2) the correlation of receptor and ligand overexpression with 
disease severity and outcome; (3) genetic alteration of c-Met by mutation of gene 
amplification in multiple cancer types; (4) introduction of c-Met and HGF (or mutant c-
Met) into cell lines, conferred the properties of tumorgenicity and metastatic propensity 
on engineered cells; (5) introduction of c-Met or HGF as transgenes into the germline of 
mice resulted in primary and secondary neoplasms; and (6) the inhibition of c-Met or 
HGF function with dominant-negative receptors, antibody antagonists (both Met and 
HGF), and biologic antagonists (e.g., NK4) have reversed cancer-associated phenotypes 
such as motility, invasion and proliferation of tumor cells, and tumor growth and 
dissemination in vivo (Christensen, 2005). 
 
A wide variety of human cancers, including brain, colorectal, gastric, and lung, 
demonstrate dysregulated c-Met activity (Liu, 2010), either by means of c-Met kinase 
overexpression (Comoglio, 2008), activating c-Met gene mutations and/or amplification 
(Comoglio, 2008), (Jeffers, 1997), (Schmidt, 1997), or increased autocrine and/or 
paracrine secretion of the c-Met ligand, HGF/SF (Birchmeier, 2003), (Bocaccio, 2006).  
These alterations have been implicated in tumor progression and metastasis, and a high 
constitutive activation of c-Met has been correlated with poor clinical prognosis 
(Birchmeier, 2003). 
 
VEGFR2 is the predominant mediator of VEGF-stimulated endothelial cell migration, 
proliferation, survival, and enhanced vascular permeability (Kurzrock, 2011).  Increased 
expression of VEGFR2, often in combination with VEGFR3, has been observed in the 
tumor vascular endothelium in most common human solid tumor types, on tumor cells in 
melanoma and hematological malignancies, and in colitis-associated colon cancer 
(Tugues, 2011).  High VEGFR2 expression is an unfavorable prognostic biomarker in 
hepatocellular carcinoma (HCC), and correlated with triple-negative (i.e., therapy-
resistant) breast cancer and poor survival. 
 
Nonclinical Development of Cabozantinib   
 
In Vivo Activity 
Inhibition of VEGF signaling pathway was previously shown to result in more invasive 
tumors in the transgenic RIP-Tag2 mouse model of pancreatic neuroendocrine cancer that 
spontaneously develops aggressive tumors (Paez-Ribes, 2009).  In RIP-Tag2 transgenic 
mice, tumors treated with cabozantinib were smaller (P <0.05) than in mice treated with 
vehicle or an anti-VEGF antibody, but were also less invasive (P <0.05) and had no liver 
metastases (Sennino, 2009).  All mice treated with cabozantinib (n = 6) survived until 20 
weeks, but none treated with vehicle (n = 14) or anti-VEGF antibody (n = 8) reached that 
endpoint.  Tumor vascularity decreased after treatment, with reductions ranging from 
67% at 3 mg/kg to 83% at 30 mg/kg for 7 days (You, 2011).  Tumors were 35% smaller 
after cabozantinib treatment than corresponding values for vehicle control mice.  c-Met

Version Date: February 17, 2017 
 
 
15 
 
protein expression in tumors was slightly decreased, but phosphorylated c-Met was 
markedly reduced after treatment for 7 days.   
 
Mice bearing MDA-MB-231 cells (expressing MET and VEGF) were administered four 
oral doses of 100 mg/kg (Yakes, 2011).  Cabozantinib increased tumor hypoxia (13-fold) 
and apoptosis (TUNEL; 2.5-fold) at 8 and 4 hours after the first and second doses, 
respectively, when compared to vehicle-treated tumors.  In addition, Cabozantinib 
disrupted tumor vasculature by inducing endothelial cell death that negatively affected 
tumor viability.  Cabozantinib treatment resulted in significant tumor growth inhibition of 
MDA-MB-231 tumors (P <0.001) at all doses (1, 3, 10, 30, or 60 mg/kg) when compared 
to vehicle-treated tumors.  Dose-dependent inhibition was observed for the 3 and 10 
mg/kg doses (P <0.01), and complete inhibition was observed at the 30 and 60 mg/kg 
doses.  A single 100 mg/kg dose resulted in sustained MDA-MB-231 tumor growth 
inhibition for ~8 days after which tumors began growing at a rate similar to vehicle-
treated control tumors.  In addition, cabozantinib inhibited tumor growth (P <0.001) in 
the MET-expressing rat C6 glioma cell line for all doses (1, 3, 10, 30, or 60 mg/kg) when 
compared with vehicle-treated tumors.  The 3 mg/kg and 10 mg/kg doses resulted in 
significant tumor regression (62% and 85%, P <0.0001) when compared with predose 
tumor weights.  Subchronic administration of cabozantinib was well tolerated in mice and 
rats with no signs of toxicity, as determined by stable and/or increasing body weights 
during the treatment period. 
 
ARCaP-M is a human prostate cancer model which expresses both c-Met and VEGF co-
receptor NP-1 used in a human prostate tumor xenograft study in mouse bone (Zhang, 
2010). ARCaP-M cells were injected into the tibia of nude mice on Day 1, and on Day 31 
animals with established bone lesions were randomized to receive Cabozantinib or 
vehicle daily (qd) for 7 weeks of treatment(Investigator’s Brochure, 2011).  Tibiae from 
vehicle-treated animals exhibited both osteoblastic and osteolytic lesions, whereas tibiae 
from Cabozantinib treated animals appeared mostly normal.  Thus, Cabozantinib 
treatment blocked both osteoblastic and osteolytic progression of ARCaP-M xenograft 
tumors in bone. 
 
Nonclinical Pharmacodynamics 
In mice, the effective dose resulting in 50% inhibition (ED50) of targets was achieved at 
well tolerated doses of Cabozantinib and at plasma exposures comparable to exposure 
observed in clinical trials (Investigator’s Brochure, 2010).  Cabozantinib produced 
prolonged inhibition of receptor phosphorylation, such as sustained inhibition of c-Met 
and VEGFR2 for 10 hours after administration of a single dose of cabozantinib.  This 
extended inhibition occurred in a manner that was generally predicted by plasma 
exposure, i.e., inhibition was diminished when plasma levels fell below approximately 20 
μM for c-Met, 5 μM for VEGFR2, and 23 μM for TIE-2. 
 
Once daily administration of cabozantinib resulted in significant inhibition of c-Met 
phosphorylation in TT tumors, relative to tumors from vehicle control-treated mice, with 
maximal inhibition of 70% seen at 60 mg/kg (Investigator’s Brochure, 2010).  Dose-
dependent inhibition of phosphorylation of c-Met and RET was observed among the 3, 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
 
16 
 
10, and 30 mg/kg dose groups as well.   
 
c-Met phosphorylation was inhibited by a single 100 mg/kg oral dose of Cabozantinib, 
2–8 hours post dose in H441 tumors (human lung papillary adenocarcinoma) that harbor 
constitutively phosphorylated c-Met (Yakes, 2011). This effect was reversible, as c-Met 
phosphorylation returned to basal levels by 48 hours after treatment.   
 
Nonclinical Pharmacokinetics 
In the various xenograft models, plasma exposures were similar and plasma 
concentrations in the range of 3 to 27 μM were associated with efficacy (Investigator’s 
Brochure, 2010).  In rats, plasma concentrations in the range of 5 to 15 μM were 
associated with maximal anti-tumor activity.  Despite the apparent requirement for high 
peak concentrations, trough concentrations as low as 0.1 μM were observed at highly 
efficacious doses in mice.  These results were consistent with in vivo target modulation 
studies in mice which demonstrated long (4- to 10-hour) durations of action, and 
indicated that continuous high exposure was not required to maintain efficacy.   
 
Dose proportional increases in exposure occurred at oral doses of 3–100 mg/kg in mice 
and at 3–30 mg/kg in rats (Investigator’s Brochure, 2010).  In rats, the oral bioavailability 
of cabozantinib dosed as a solid was approximately 100% of cabozantinib dosed as a 
liquid.  In comparison, oral bioavailability was much lower in dogs (20%) and monkeys 
(18%) for the solid versus liquid dosage forms. 
 
Systemic drug exposure parameters (maximum plasma concentration [Cmax] and area 
under the time-concentration curve from 0 to t hours post-dose [AUC0-t] values) 
associated with single cabozantinib  oral doses in rats increased less than dose-
proportionally with increasing dose (100–900 mg/kg) (Investigator’s Brochure, 2010).  
With repeat daily oral dosing in rats, systemic exposure (AUC0-t values) increased 
generally dose-proportionally following 14 and 178 dosing days (dose ranges 1–15 
mg/kg/day and 0.1–1 mg/kg/day, respectively).  The Cmax and AUC0-t values in rats 
administered 100 mg/kg were approximately 2-fold and 3-fold higher, respectively, than 
for dogs given 2000 mg/kg; therefore, the higher systemic exposure to cabozantinib in 
rats correlated with the greater toxicity observed in this species at lower administered 
doses. 
 
Systemic drug exposure parameters (Cmax and AUC0-t values) associated with single 
cabozantinib oral doses in dogs increased less than dose-proportionally with increasing 
Cabozantinib dose (400–2000 mg/kg), suggesting possible saturation of systemic 
absorption (Investigator’s Brochure, 2011).  With repeat daily dosing, exposure (Cmax and 
AUC0-24 values) both increased greater than dose-proportionally from 10 to 100 mg/kg 
and less than dose proportionally from 100 to 1000 mg/kg following 14 dosing days.   
 
Toxicology 
In rodents and non-rodents, histopathological changes associated with cabozantinib 
administration were observed in gastrointestinal (GI) tract, bone marrow, lymphoid 
tissues, kidney, and adrenal and reproductive tract tissues (Investigator’s Brochure, 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
 
17 
 
2011).  Histopathological changes present in the bone and pancreas were considered 
secondary to cabozantinib administration. Adverse effects following oral exposure to 
cabozantinib were generally dose-related, clinically monitorable, and self-resolving upon 
discontinuation of dosing. In 6-month chronic toxicity studies, treatment-related changes 
were present only in kidney (rats) and reproductive tissues (dog).  In 
reproductive/developmental toxicity studies, Cabozantinib administration resulted in 
decreased fertility in male and female rats, in embryotoxicity when given to pregnant 
rats, and in a visceral tissue malformation (small spleen) when given to pregnant rabbits. 
The no-observable-adverse-effect-levels (NOAELs) for the chronic toxicity and 
reproductive/developmental toxicity studies occurred at plasma exposures (AUC) below 
steady-state values measured in subjects with solid tumors administered 175 mg 
Cabozantinib capsule form daily (Study XL184-001). 
 
In definitive genotoxicity bioassays, Cabozantinib was negative in an S. 
typhimurium/E.coli bacterial mutagenicity study, an in vitro chromosome aberration 
study using human peripheral blood lymphocytes, and an in vivo mouse bone marrow 
micronucleus study (Investigator’s Brochure, 2010).  In safety pharmacology studies, no 
adverse effects occurred on neurobehavioral or respiratory functions in Cabozantinib-
treated rats or on cardiovascular function in Cabozantinib-treated dogs. 
 
Clinical Experience 
 
As of May 4, 2011, 1003 patients have been studied in 12 ongoing Exelixis-sponsored 
clinical trials with Cabozantinib treatment 1) as a single agent at does ranging from 0.08 
to 11.52 mg/kg on an intermittent dosing schedule, 2) from 25 to 265 mg (19.7-209 mg 
freebase equivalent weight) on a fixed daily dosing schedule and 3) in combination with 
temozolomide (TMZ) and radiation therapy (RT), or with erlotinib (Exelixis 
Communication, 2011).  The maximum tolerated dose (MTD) on once daily (qd) by 
mouth (PO) dosing schedule was determined to be 175 mg L-malate salt (or 
approximately 138 mg freebase equivalent weight). 
 
Detailed information for each of these studies, including pharmacokinetic data, can be 
found in the Investigator’s Brochure (2011).  Safety and efficacy information, from the 
2011 Investigator’s Brochure, is summarized below.  
 
Phase 2 Studies 
 
In a phase 2 study, XL184-201, subjects with progressive or recurrent GB in first or 
second relapse were enrolled to receive cabozantinib qd as a single agent.  Group A 
received an initial dose of 175 mg (Group A), subsequent cohorts (Groups B and C) 
received an initial dose of 125 mg.  Forty-six subjects were enrolled in Group A, and a 
total of 176 subjects were enrolled in Groups B/C.  Fifty-seven subjects experienced one 
or more serious adverse events (SAEs) that were assessed to be related to treatment, 
including five fatal related. 
 
Study XL184-203 is a phase 2 randomized discontinuation trial.  Subjects are enrolled 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
 
18 
 
into one of nine tumor-specific cohorts: breast cancer, gastric/gastroesophageal (GEJ) 
cancer, hepatocellular carcinoma (HCC), melanoma, NSCLC, ovarian cancer, pancreatic 
cancer, prostate cancer, and small cell lung cancer (SCLC).  Eligible subjects with 
advanced solid tumors receive open-label cabozantinib at starting dose of 100 mg qd for 
12 weeks.  Of the 531 subjects enrolled in this study as of May 2011, 92 experienced one 
or more SAEs that were assessed to be related to treatment with cabozantinib, including 
seven fatal related SAEs. 
 
Study XL184-205 is a randomized phase 2 trial for subjects with grade IV astrocytic 
tumors in first or second relapse.  Subjects received one of four regimens: 25 mg qd (Arm 
1) continuously, 75 mg qd (Arm 2) continuously, 125 mg qd for 2 weeks followed by 50 
mg qd continuously (Arm 3), and 125 mg qd on an intermittent 3 week on/1 week off 
schedule (Arm 4).  A total of 19 subjects were accrued before the study was terminated.  
Three subjects were rolled over to maintenance Study XL184-900.  One subject 
experienced an SAE assessed to be related to treatment with cabozantinib.  
 
Study XL184-301 is a blind trial for subjects with unresectable, locally advanced or 
metastatic MTC, randomized 2:1 to cabozantinib or placebo.  SAEs reported in Study 
XL184-301 are: one grade 4 reversible posterior leukoencephalopathy syndrome (RPLS), 
one grade 5 cardiac arrest following asystolic vagal reaction after aspiration on study 
medication, and three SAEs of acquired trachea-esophageal fistula (two grade 3, one 
grade 5). 
 
Study GOG-0186K is a phase II trial for subjects with persistent or recurrent ovarian, 
fallopian tube, or primary peritoneal cancer.  The study demonstrated a low rate of Grade 
3 and 4 toxicities with only 1 bowel perforation among 52 patients who received 
Cabozantinib.  
 
Adverse Events 
The clinical studies with cabozantinib are ongoing and thus the AE data from the clinical 
database as of March 1, 2011 and May 4, 2011 do not yet include all SAEs (Exelixis 
Communication, 2011).  As of March 2011, AE data are available for 913 subjects who 
have been dosed with Cabozantinib (806 in single-agent studies and 107 in combination 
studies of cabozantinib with erlotinib, rosiglitazone, or TMZ ± radiation) (Investigator’s 
Brochure, 2011).  Data from the 806 subjects who received single-agent cabozantinib 
show that the most frequently (>20%) observed AEs regardless of causality were fatigue, 
diarrhea, nausea, decreased appetite, constipation, palmar-plantar erythrodysesthesia 
(PPE) syndrome, vomiting, dysphonia, and hypertension.  Effects that may be related to 
the inhibition of VEGF, including hypertension, thromboembolic events, GI perforation, 
fistula formation, hemorrhage, wound dehiscence, and proteinuria, have been observed in 
the single-agent and combination cabozantinib studies.  The most commonly reported 
SAEs that were assessed as related to study treatment with cabozantinib (as a single-
agent or combination) were pulmonary embolism (PE), diarrhea, dehydration, deep vein 
thrombosis (DVT), vomiting, nausea, thrombocytopenia, fatigue, wound dehiscence, and 
PPE syndrome. 
 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
 
19 
 
There have been 15 grade 5 AEs related to study treatment: GI hemorrhage (two 
subjects), PE (two subjects), respiratory failure (two subjects), respiratory disorder (one 
subject), hemoptysis (one subject), death due to unknown cause (two subjects), 
intracranial hemorrhage (one subject), intestinal perforation (one subject), 
enterocutaneous fistula (one subject), hemorrhage (presumed to be hemoptysis; one 
subject), and diverticular perforation, peritonitis (one subject) (Investigator’s Brochure, 
2011). 
 
Pharmacokinetics 
Pharmacokinetic analysis of 74 patients in trial XL184-001 showed dose proportional 
increases in maximum plasma concentration (Cmax) and AUC both for PIB (dose range 
0.08-11.52 mg/kg) and the capsule formulation (dose range: 125 to 175 mg) (Kurzrock, 
2011).  Terminal-phase half-life (t1/2,z) values were 59.1 to 136 hours (Investigator’s 
Brochure, 2011).  After repeat dosing, t1/2,z values (mean ± standard deviation) for 
cabozantinib were 91.3 ± 33.3 hours (n = 23), and apparent steady-state plasma levels 
were reached by Day 15 18.  Steady-state clearance for the 175 mg capsule dose derived 
from repeat dose data was 4.2 ± 1.5 L/h.  Patients who received 175 mg capsules had 
four- to five-fold higher steady-state exposure (AUC) compared with Day 1 (7.68 ± 2.85 
mcg∙h/mL; n = 23 vs. 41.6 ± 15.3 mcg∙h/mL; n = 23), indicating that cabozantinib 
accumulated with repeat daily dosing.  There was no significant difference in exposure 
between patients with MTC and those without MTC. 
 
Based on the preliminary PK data from 23 subjects in XL184-005 who completed both 
treatments, after a single oral dose of cabozantinib at 100 mg, the terminal t1/2, z of 
cabozantinib appeared to be similar for both tablet and capsule formulations, with 
approximately mean values of 110 hours (Exelixis Communication, 2012).  The median 
time to the maximum plasma concentration (tmax) was 4 hours for the tablet formulation 
and 5 hours for the capsule formulation.  High inter-subject variability for Cmax and the 
area under the plasma drug concentration time curve (AUC) values were observed for 
both formulations (coefficient of variation [CV]% Cmax: 51% for the tablet formulation, 
61% for the capsule formulation; CV% for the AUC from time zero to the last 
quantifiable timepoint or to infinity [AUC0-last or AUC0-inf]: 40-43% for the tablet 
formulation, 43% for the capsule formulation).  The geometric mean Cmax of the tablet 
formulation was approximately 39% higher than the value observed for the capsule 
formulation.  The geometric mean AUC0-last and AUC0-inf values for the tablet formulation 
were also higher (15% and 19%, respectively) than those observed for the capsule 
formulation.  However, due to the high within-formulation variability observed, no 
statistical difference in exposure between the two formulations was apparent. 
 
Based on the preliminary PK data from 46 subjects who completed both treatments on 
trial XL184-004, a high-fat meal did not appear to alter the terminal t1/2, z of cabozantinib 
[mean t1/2, z : 131 hours (fed) vs 128 hours (fasted)].  The high-fat meal significantly 
increased the median tmax to 6 hours from 4 hours (fasted).  The high-fat meal also 
significantly increased both the cabozantinib Cmax and AUC values by 39% and 56%, 
respectively.  The geometric mean ratio of Cmax fed/fasted was 1.39 (90% CI: 1.16-1.67), 
and the geometric mean ratio of AUC0-last fed/fasted was 1.56 (90% CI: 1.34-1.80).

Based on this result, cabozantinib must be taken on an empty stomach (fasting is required 
2 hours before and 1 hour after each cabozantinib dose).

solely based on CA-125. Primary tumors must be at least 50% clear cell 
histomorphology in order to be eligible or have a histologically documented recurrence 
with at least 50% clear cell histomorphology. Recurrence should be biopsy proven 
unless the tumor is located in an area deemed unsafe to biopsy by the surgeon. If a 
biopsy can be obtained without significant risk, then biopsy should be obtained 
 
3.2.1.1 
If the primary tumor had at least 50% clear cell histomorphology, a biopsy of the 
recurrent or persistent tumor is not required. The percentage of clear cell 
histomorphology must be documented in the pathology report or in an addendum to 
the original report. If slides of the primary tumor are not available for review due to 
disposal of slides by the histology laboratory (typically 10 years after diagnosis), 
biopsy of recurrent or persistent disease is required. 
 
3.2.1.2 
If slides of the primary tumor are not available for review, a biopsy of the recurrent or 
persistent tumor is required to confirm at least 50% clear cell histomorphology. The 
percentage of involvement must be documented in the pathology report or in an 
addendum to the original report.

Version Date: February 17, 2017 
 
5.2 
General Concomitant Medication and Supportive Care Guidelines 
5.2.1 Because there is a potential for interaction of cabozantinib with other concomitantly 
administered drugs through the cytochrome P450 system, the case report form must 
capture the concurrent use of all other drugs, over-the-counter medications, or 
alternative therapies.  The Principal Investigator should be alerted if the patient is taking 
any agent known to affect or with the potential to affect selected CYP450 isoenzymes.   
 
5.2.2 Concomitant Medications and Therapies 
 
5.2.2.1 
Anticancer Therapy 
 
If a subject requires additional systemic anticancer treatment, study treatment must be 
discontinued.  Local intervention is discouraged unless medically unavoidable.  
 
5.2.2.2 
Other Medications 
 
Subjects must be instructed to inform the investigators of the current or planned use 
or all other medications during the study (including prescription medications, over-
the-counter medications, vitamins and herbal and nutritional supplements).  It is the 
responsibility of the investigator to ensure that details regarding all medications are 
documented. 
 
Bisphosphonates started prior to screening activities or initiated during the course of 
the study to control bone pain may be used with caution. 
 
Colony stimulating factors (e.g., erythropoietin and granulocyte colony-stimulating 
factors) and pain medications administered as dictated by standard practice are 
acceptable while the subject is enrolled in the study.  However, colony stimulating 
factors should not be administered prophylactically prior to the first dose of study 
treatment.  
 
No concurrent investigational agents are permitted. 
 
5.2.2.3 
Potential Drug Interactions 
 
CYP450 isozymes: 
In vitro, XL184 is a substrate of CYP3A4 and a weak substrate of CYP2C9. Co-
administration of ketoconazole, a strong inhibitor of CYP3A4, increases XL184 AUC (37%) 
and rifampin, a strong inducer of CYP3A4, reduces XL184 AUC (77%) . Therefore, avoid 
chronic use of strong CYP3A4 inducers such as rifampin, dexamethasone, phenytoin, 
carbamazepine, rifabutin, rifampentin, phenobarbital, and St. John’s Wort while taking 
XL184. Avoid chronic use of strong CYP3A4 inhibitors such as ketoconazole, itraconazole, 
clarithromycin, indinavir, nefazodone, nelfinavir, and ritonavir. Use alternative medications. 
 
[Note: Use caution when discontinuing medication that is a strong inducer of CYP3A4 in 
patients who has been on a stable dose of XL184, as this could significantly increase the 
exposure to XL184.] 
 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
28  
Version Date: February 17, 2017 
 
XL184 is a noncompetitive inhibitor of CYP2C8 (Kiapp = 4.6 μM), a mixed-type inhibitor of 
both CYP2C9 (Kiapp = 10.4 μM) and CYP2C19 (Kiapp = 28.8 μM), and a weak competitive 
inhibitor of CYP3A4 (estimated Kiapp = 282 μM) in human liver microsomal (HLM). IC50 
values >20 μM were observed for CYP1A2, CYP2D6, and CYP3A4 isozymes. XL184 is an 
inducer of CYP1A1 mRNA in human hepatocyte incubations, 
 
Avoid grapefruit/ grapefruit juice and Seville oranges while participating in this trial. 
 
P-glycoprotein/ MRP2: 
In vitro data indicate that XL184 is unlikely to be a substrate but may be an inhibitor of P-
glycoprotein transport activity (IC50 = 7.0 μM). Co-administration of XL184 with a P-gp 
substrate may result in an increase in P-gp substrate plasma concentration. Therefore, use 
caution when administering XL-184 with drugs known to be P-gp substrates (e.g., 
fexofenadine, aliskiren, ambrisentan, digoxin, colchicine, maraviroc, posaconazole, tolvaptan, 
etc.). In an in vitro assay, XL184 has shown to be a substrate of drug transporter MRP2, 
which may result in an increase plasma concentration of XL184 when administered with an 
inhibitor of MRP2. Use caution and monitor adverse events when administering XL184 with 
MRP2 inhibitors such as cyclosporine, delavirine, efavirenz, emtricitabine. 
 
Please refer to the Flockhart drug interaction tables for lists of substrates, inducers, 
and inhibitors of selected CYP450 isozyme pathways. Table available at (Flockhart 
2007; http://medicine.iupui.edu/clinpharm/ddis/table.aspx).  
 
Protein bound: 
XL184 is highly protein bound (≥ 99.9%). Use caution when coadministering XL184 with 
medications that are highly protein-bound (e.g., diazepam, furosemide, dicloxacillin, and 
propranolol). Avoid administration of warfarin with XL184 as warfarin is highly protein-
bound and has a very narrow therapeutic index. 
 
Antacids, H2-blockers, PPIs: 
Co-administration of gastric pH modifying drugs such as PPI, H2-blockers or antacids has no 
clinically-relevant effect on XL184 plasma PK in healthy volunteers; thus, concomitant use 
of these drugs with XL184 is allowed. 
 
QTc prolongation: 
Use caution when administering XL184 in patients with QT prolongation risk, a history of 
QT interval prolongation, or who are receiving antiarrhythmic drugs. Concomitant use of 
strong CYP3A4 inhibitors should be avoided as itmay increase XL184 plasma 
concentrations. Refer to the protocol for QTcF criteria. 
 
 
 
5.2.3  
Participation in Other Trials  
• Patients must not be eligible for a higher priority NRG clear cell protocol (GOG-
0283). Rare patients ineligible for GOG-0283 may be eligible for this trial without 
prior treatment on dasatinib therapy (e.g. they have been deemed allergic to 
dasatinib).

6. TREATMENT MODIFICATIONS/MANAGEMENT 
 
6.1 
Cabozantinib (XL184)-Related Adverse Event Management 
 
Subjects will be monitored continuously for AEs throughout the study. Subjects must be 
instructed to notify their physician immediately for any and all toxicities. 
 
General guidelines for the management of non-hematologic and hematologic toxicities are 
provided in Table 6-1 and Table 6-2, respectively. As a general approach, it is suggested that all 
AEs be managed with supportive care when possible at the earliest signs of toxicity. Calcium, 
magnesium, potassium and phosphorus should be kept above the lower limits of the laboratory 
normal values. For more specific guidelines on gastrointestinal AEs (diarrhea, nausea/vomiting, 
stomatitis/mucositis), hepatobiliary disorders, pancreatic disorders including lipase and amylase 
elevations, skin disorders (PPE), embolism and thrombus, hypertension, proteinurea, 
hemorrhage, rectal and perirectal abscess, gastrointestinal (GI) perforation and GI fistula, non-GI 
fistula, wound healing and surgery, osteonecrosis of the jaw (ONJ),  endocrine disorders and 
management of treatment-emergent prolongation of the QTc interval, refer to the appropriate 
below.  Guidance for the management of fatigue, anorexia, weight loss, eye disorders, 
musculoskeletal and connective tissue disorders, nervous system disorders, 
respiratory/thoracic/mediastinal disorders and congenital, familial and genetic disorders can be 
found in the Cabozantinib Investigator’s Brochure.

cabozantinib that are intolerable to the 
subject or deemed unacceptable in the 
investigator’s judgment; or are not 
easily managed or corrected 
Dose reduce 
• 
If the AE dose not resolve to Grade ≤1 or baseline in 7 to 10 days 
or worsens at any time, cabozantinib dosing should then be 
interrupted.  Then upon resolution to baseline or Grade ≤ 1, the 
reduced dose should be restarted. 
• 
If the AE does resolves to resolves to Grade ≤1 or baseline 
without a dose interruption, continue the reduced dose. 
Grade 3: 
 
Grade 3 AEs considered related to 
cabozantinib which occurred without 
optimal prophylaxis or which is easily 
managed by medical intervention or 
resolved quickly 
• 
Interrupt cabozantinib and add supportive care as indicated 
• 
For AEs that are easily managed (e.g., correction of electrolytes) 
with resolution to baseline or Grade ≤1 within 24 hours,  
cabozantinib may be resumed at either the same dose or with a 
dose reduction at the discretion of the investigator unless this is a 
recurring event at which time the dose should be reduced 
• 
For AEs that require supportive care, the dose should be held 
while supportive care is initiated and optimized.  Then upon 
resolution of the AE to baseline or Grade ≤1,  cabozantinib may be 
resumed at either the same dose or with a dose reduction at the 
discretion of the investigator unless this is a recurring event at 
which time the dose should be reduced 
Grade 3 AEs considered related to 
study treatment that occurred despite 
optimal prophylaxis or is not easily 
managed by medical intervention  
Interrupt study treatment until recovery to ≤ Grade 1 or baseline, and 
resume treatment with a dose reduction 
Grade 4: 
 
Grade 4 AEs considered related to 
study treatment 
Permanently discontinue study treatment unless determined that the 
subject is unequivocally deriving clinical benefit.  In this case, upon 
recovery to Grade ≤1 or baseline, the subject may be re-treated at a 
reduced dose that is to be determined by the investigator and sponsor 
but only with sponsor approval. 
Dose reductions or delays may occur in the setting of lower grade toxicity than defined above if the 
investigator believes that it is in the interest of the subject’s safety.

Diarrhea, Nausea, Vomiting,  Stomatitis, and Mucositis 
 
Diarrhea 
 
Subjects should be instructed to notify their physician immediately at the first signs of poorly 
formed or loose stool or an increased frequency of bowel movements.  Administration of 
antidiarrheal agents is recommended at the first sign of diarrhea as initial management.  
Loperamide is recommended as standard first line therapy.  Alternatively, diphenoxylate/atropine 
can be used.  Additional agents to consider in subjects with diarrhea that is refractory to the 
above include deodorized tincture of opium and octreotide (Benson et al., 2004).  Some subjects 
may require concomitant therapy with loperamide, diphenoxylate/atropine, and deodorized 
tincture of opium to control diarrhea.  The dose modification guidance in Table 6-1 should be 
followed.  In addition, general supportive measures should be implemented including continuous 
oral hydration, correction of fluid and electrolyte abnormalities, small frequent meals, and 
stopping lactose-containing products, high fat meals and alcohol.  
 
Nausea and Vomiting 
 
Anti-emetic agents along with supportive care are recommended as clinically appropriate at the 
first sign of nausea and vomiting.  The dose modification guidance in Table 6-1 should be 
followed.   
 
The 5-HT3 receptor antagonists are recommended over chronic use of NK-1 receptor antagonists 
and dexamethasone (NK-1 receptor antagonists can induce or inhibit CYP3A4, and 
glucocorticoids induce CYP3A4 and thus could lower cabozantinib exposure.  Caution is also 
recommended with the use of nabilone, which is a weak inhibitor of CYP3A4. Caution is also 
recommended with ondansetron, as ondansetron may result in QTc prolongation when 
administered with cabozantinib.  Ondansetron is a 5-HT3 antagonist. 
 
Stomatitis and Mucositis 
 
Preventive measures may include a comprehensive dental examination to identify any potential 
complications before study treatment is initiated.  Appropriate correction of local factors should 
be instituted as indicated, such as modification of ill-fitting dentures and appropriate care of 
gingivitis.  During treatment with cabozantinib, good oral hygiene and standard local treatments 
such as non-traumatic cleansing, and oral rinses (e.g., with a weak solution of salt and baking 
soda) should be maintained.  The oral cavity should be rinsed and wiped after meals, and 
dentures should be cleaned and brushed often to remove plaque. Local treatment should be 
instituted at the earliest onset of symptoms.  When stomatitis interferes with adequate nutrition 
and local therapy is not adequately effective, dose reduction or temporary withholding of 
cabozantinib should be considered. 
 
6.3 
Hepatobiliary Disorders 
 
Elevations of transaminases have also been observed during treatment with cabozantinib.  In 
general, it is recommended that subjects with elevation of ALT, AST, and/or bilirubin have more

frequent laboratory monitoring of these parameters.  If possible, hepatotoxic concomitant 
medications and alcohol should be discontinued in subjects who develop elevated transaminases.  
Since subjects may enter the study with elevations of AST/ALT at baseline, the following 
guideline should be used for dose modifications: 
 
 
 
Transaminase elevation 
CTCAE v4.0 
 
Intervention 
Subjects with AST and ALT less than or equal to the ULN at baseline 
Grade 1  
Continue cabozantinib with weekly monitoring of liver function tests (LFTs) for at 
least 4 weeks. Then resume the standard protocol-defined monitoring of LFTs. 
Grade 2 
Continue cabozantinib with at least twice weekly monitoring of LFTs for 2 weeks. 
Then weekly for 4 weeks.  If LFTs continue to rise within Grade 2, interrupt 
cabozantinib treatment.   Then continue with at least weekly LFTs until resolution 
to Grade ≤ 1.  Study treatment may then be resumed at a one-dose-level reduction 
of cabozantinib 
Grade 3  
Interrupt cabozantinib treatment and monitor with at least twice weekly LFTs until 
Grade ≤ 2.  Then continue with at least weekly LFTs until resolution to Grade ≤ 1.  
Cabozantinib may then be resumed at a one-dose-level reduction.  
Grade 4 
Discontinue study treatment permanently. LFTs should be monitored as clinically 
indicated, at least 2-3 times per week, until resolution to Grade ≤ 1.   If the subject 
was unequivocally deriving clinical benefit, the subject may be able to resume 
treatment at a lower dose of cabozantinib as determined by the investigator and 
sponsor but only with sponsor approval. 
Subjects with AST or ALT above the ULN  but ≤ 3.0 x ULN (i.e., Grade 1) at  baseline   
≥ 1.5 fold increase of AST or 
ALT AND both AST and 
ALT are ≤ 5.0 x ULN 
Continue cabozantinib treatment with at least twice weekly monitoring of LFTs 
for 4 weeks and weekly for 4 weeks.  If LFTs continue to rise, interrupt study 
treatment.   Then continue with at least weekly LFTs until resolution to Grade ≤ 1.  
Study treatment may then be resumed at a one-dose-level reduction of 
cabozantinib 
≥ 1.5 fold increase of AST or 
ALT and at least one of 
AST or ALT is Grade 3 (i.e. 
AST or ALT > 5.0 but ≤ 
20.0 x ULN) 
Interrupt study treatment and monitor with at least twice weekly LFTs until 
Grade ≤ 2.  Then continue with at least weekly LFTs until resolution to Grade ≤ 1.  
Study treatment may then be resumed at a one-dose-level reduction of 
cabozantinib. 
Grade 4  
Discontinue study treatment permanently. LFTs should be monitored as clinically 
indicated, at least 2-3 times per week, until resolution to Grade ≤ 1.  If the subject 
was unequivocally deriving clinical benefit, the subject may be able to resume 
treatment at a lower dose as determined by the investigator and sponsor but only 
with sponsor approval.

Cabozantinib treatment should also be interrupted when transaminase increases are accompanied 
by progressive elevations of total bilirubin, and/or elevations of coagulation tests (e.g., 
International Normalized Ratio [INR]).  Monitoring of transaminases should be intensified (2–3 
times per week) and cabozantinib should be held until the etiology of the abnormalities is 
determined and these abnormalities are corrected or stabilize at clinically acceptable levels (INR 
< 1.5  ULN, total bilirubin < 1.5  ULN, aminotransferases ≤ baseline grade).  
 
Subjects must have cabozantinib permanently discontinued if transaminase elevations are 
accompanied by evidence of impaired hepatic function (bilirubin elevation >2 ULN), in the 
absence of evidence of biliary obstruction (i.e., significant elevation of alkaline phosphatase) or 
some other explanation of the injury (e.g., viral hepatitis, alcohol hepatitis), as the combined 
finding (i.e., Hy’s Law cases) represents a signal of a potential for the drug to cause severe liver 
injury. 
 
All subjects who develop isolated bilirubin elevations of Grade 3 should have study treatment 
held until recovered to Grade ≤1 or baseline (or lower).  If this occurs within 6 weeks of the 
dosing delay, study treatment may continue at a reduced dose. In subjects without biliary 
obstruction and Grade 4 bilirubin elevation, or with recurrence of Grade 3 bilirubin elevation 
after a dose reduction, study treatment must be discontinued.  
 
6.4 
Pancreatic Conditions 
 
Amylase and lipase elevations have been observed in clinical studies with cabozantinib.  The 
clinical significance of asymptomatic elevations of enzymes is not known but in general have not 
been associated with clinically apparent sequelae.  It is recommended that subjects with lipase 
elevation and/or symptoms of pancreatitis have more frequent laboratory monitoring of lipase 
and/or amylase (2-3 times per week). Subjects with symptomatic pancreatitis should be treated 
with standard supportive measures.

Skin Disorders 
 
Palmar-plantar erythrodysesthesia syndrome (PPE; also known as hand-foot syndrome), skin 
rash (including blister, erythematous rash, macular rash, skin exfoliation, dermatitis acneiform,

and papular rash), pruritus, dry skin, erythema, pigmentary changes, and alopecia have been 
reported in cabozantinib-treated subjects.  All subjects on study should be advised to use 
prophylactic measures for skin care.  These measures includes the use of hypoallergenic 
moisturizing creams, ointment for dry skin, sunscreen with SPF ≥30; avoidance of exposure of 
hands and feet to hot water; protection of pressure-sensitive areas of hands and feet; and use of 
thick cotton gloves and socks to prevent injury and to keep the palms and soles dry. Subjects 
with skin disorders should be carefully monitored for signs of infection (e.g., abscess, cellulitis, 
or impetigo). 
 
Early signs of hand-foot syndrome can include tingling, numbness, and slight redness or mild 
hyperkeratosis.  Early manifestations include painful, symmetrical red and swollen areas on the 
palms and soles.  The lateral sides of the fingers or periungual zones may also be affected.  
Adequate interventions are required to prevent worsening of skin symptoms such as blisters, 
desquamations, ulcerations, or necrosis of affected areas.  Aggressive management of symptoms 
is recommended, including early dermatology referral. 
 
Treatment guidelines for PPE related to study treatment are presented in the table below. 
 
In the case of study treatment-related skin changes (e.g., rash, hand-foot syndrome), the 
investigator may request that additional assessments be conducted with the subject’s consent.  
These assessments may include digital photographs of the skin changes and/or a biopsy of the 
affected skin and may be repeated until the skin changes resolve.

Hand-Foot Skin Reaction and Hand Foot Syndrome (PPE) 
Grade 1 
Continue cabozantinib at current dose if tolerable or reduce to the next lower 
dose if intolerable. Start urea 20% cream twice daily AND clobetasol 0.05% 
cream once daily. Assess subject at least weekly for changes in severity.  
Subjects should be instructed to notify investigator immediately if severity 
worsens.  If severity worsens at any time or if there is no improvement after 2 
weeks, proceed to the management guidelines for Grade 2 PPE 
Grade 2 
Reduce cabozantinib dose to next lower level and/or interrupt dosing. 
Start/continue urea 20% cream twice daily AND clobetasol 0.05% cream once 
daily. Add analgesics for pain control with NSAIDs/GABA agonists/narcotics if 
needed.. Assess subject at least weekly for changes in severity.  Subjects should 
be instructed to notify investigator immediately if severity worsens.  If severity 
worsens at any time, or affects self-care, or if there is no improvement after 2 
weeks, proceed to the management guidelines for Grade 3 PPE.  If the dose was 
only reduced but not interrupted, treatment may continue at the reduced dose.  If 
the dose was only interrupted but not reduced, then treatment may be restarted 
upon resolution to Grade 0 or Grade 1 at one dose level lower. 
Grade 3 
Interrupt study treatment until severity decreases to Grade 1 or 0.  Start/continue 
urea 20% cream twice daily AND clobetasol 0.05% cream once daily.  Pain 
control with NSAIDs/GABA agonists/narcotics.  Treatment may restart at one 
dose level lower when reaction decreases to Grade 1 or 0.  Permanently 
discontinue subject from study if reactions worsen or do not improve within 6 
weeks.  
GABA, γ-aminobutyric acid; NSAID, nonsteroidal anti-inflammatory drugs; PPE, palmar-plantar erythrodysesthesia 
 
6.6 
Embolism and Thrombosis  
 
Deep vein thrombosis and PE have been observed in clinical studies with cabozantinib; including 
fatal events (please refer to the IB).  Subjects who develop a PE or DVT should have study 
treatment held until therapeutic anticoagulation with heparins is established.  Study treatment 
may be resumed with a one dose-level reduction in subjects who have uncomplicated PE or DVT 
and are deriving clinical benefit from study treatment.  During treatment with anticoagulants, 
subjects need to be monitored on an ongoing basis for bleeding risk and signs of bleeding.  
Subjects with life-threatening PE or DVT should have study treatment discontinued unless 
toxicity can be managed and subject is deriving clear clinical benefit as determined by the 
investigator and agreed by the Sponsor.  Venous filters (e.g. vena cava filters) are not 
recommended due to the high incidence of complications associated with their use.  Once a 
subject is fully anticoagulated, treatment can be restarted per investigator judgment at one dose 
lower.  Subjects should permanently discontinue after a second thrombotic event.  Although 
routine prophylactic anticoagulation is not necessary for all subjects, prophylactic 
anticoagulation is allowed for individual subjects at the discretion of the investigator.

Version Date: February 17, 2017 
 
Arterial thrombotic events (e.g., transient ischemic attack, myocardial infarction) have been 
observed rarely in studies with cabozantinib.  Cabozantinib should be discontinued in subjects 
who develop an acute MI or any other clinically significant arterial thromboembolic 
complication. 
 
6.7 
Hypertension 
 
Hypertension is a relatively common complication of other VEGF-pathway inhibitors and has 
been observed in cabozantinib clinical studies. 
 
Decisions to decrease or hold the dose of study treatment must be based on BP readings taken by 
a medical professional and must be confirmed with a second measurement at least 5 minutes 
following the first measurement.  Subjects with known hypertension should be optimally 
managed prior to study entry.  Clinical judgment should be used in deciding whether new or 
worsened hypertension emerging during treatment with cabozantinib requires immediate therapy, 
or whether therapeutic intervention can be delayed in order to confirm the finding of new or 
worsened hypertension at a second visit before taking new therapeutic action.  It is recommended 
that this second visit occur within 1 week.  Blood pressure should be monitored in a constant 
position visit to visit, either sitting or supine.  Cabozantinib dosing should be interrupted in 
subjects with severe hypertension (180 mm Hg systolic or 120 mm Hg diastolic; or sustained 
≥160 mm Hg systolic or ≥110 diastolic) who cannot be controlled with medical interventions and 
discontinued in subjects with hypertensive crises or hypertensive encephalopathy (see next Table 
below).

Subjects not receiving optimized anti-hypertensive therapy 
> 140 mm Hg (systolic) and < 160 mm Hg 
OR 
> 90 mm Hg (diastolic) and < 110 mm Hg 
 
 
• Increase antihypertension therapy  (i.e., increase dose of 
existing medications and/or add new antihypertensive 
medications)  
• Maintain dose of cabozantinib 
• If optimal antihypertensive therapy (usually to include 
3 agents) does not result in blood pressure < 140 systolic or < 
90 diastolic, or if the subject is symptomatic, the dose of 
cabozantinib should be reduced. 
≥ 160 mm Hg (systolic) and < 180 mm Hg 
OR 
≥ 110 mm Hg (diastolic) and < 120 mm Hg 
• Reduce cabozantinib by one dose level. 
• Increase antihypertension therapy  (i.e., increase dose of 
existing medications and/or add new antihypertensive 
medications)  
• Monitor subject closely for hypotension. 
• If optimal antihypertensive therapy (usually to include 
3 agents) does not result in blood pressure < 140 systolic or < 
90 diastolic, dose of cabozantinib should be reduced further. 
≥ 180 mm Hg (systolic) OR 
≥ 120 mm Hg (diastolic ) 
• Interrupt treatment with cabozantinib Add new or additional 
anti-hypertensive medications and/or increase dose of 
existing medications. 
• Monitor subject closely for hypotension. 
• When SBP < 140 and DBP < 90, restart cabozantinib 
treatment at  one dose level lower 
• If optimal antihypertensive therapy (usually to include 
3 agents) does not result in blood pressure < 140 systolic or < 
90 diastolic, dose of cabozantinib should be reduced further. 
Hypertensive crisis or hypertensive 
encephalopathy 
Discontinue all study treatment 
BP, blood pressure, SBP systolic blood pressure, DBP diastolic blood pressure 
NOTE:  If SBP and DBP meet different criteria in table, manage per higher dose-modification criteria 
 
 
 
6.8 
Proteinuria 
 
Proteinuria has been reported with approved drugs that inhibit VEGF pathways as well as with 
cabozantinib.  Any level of proteinuria diagnosed by dipstick should be quantified by a UPCR 
(mg/dL protein / mg/dL creatinine).  When a UPCR exceeds 1, a repeat UPCR or a 24-hour urine 
protein and creatinine should be performed to confirm the result. Cabozantinib should be 
discontinued in subjects who develop nephrotic syndrome (proteinuria >3.5 g/day in 
combination with hypoalbuminemia, edema and hyperlipidemia) or any other relevant renal 
disease.  Also, given the nephrotoxic potential of bisphosphonates, these agents should be used 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
40  
Version Date: February 17, 2017 
 
with caution in patients receiving treatment with cabozantinib.  Details of management are 
described in the next Table below. 
 
Management of Treatment Emergent Proteinuria 
 Urine Protein/Creatinine Ratio 
Action To Be Taken 
≤ 1 
• 
No change in treatment or monitoring 
> 1 and < 3.5 
 
• 
No change in study treatment required  
• 
Consider confirming with a 24-hour protein excretion within 7 
days 
• 
Repeat UPCR within 7 days and once every week. If UPCR is < 
1 on two consecutive readings, then UPCR monitoring can revert 
to protocol specific time points. (The second reading is a 
confirmatory reading and can be done within 1 week of the first 
reading.). 
≥ 3.5 
 
• 
Hold cabozantinib immediately and confirm with 24 hour urine 
protein excretion.  
• 
Evaluate for nephrotic syndrome. If present, discontinue 
cabozantinib treatment permanently, and monitor subject for 
resolution of nephrotic syndrome.  
• 
If proteinuria of ≥ 3.5 g/24 hours is confirmed without diagnosis 
of nephrotic syndrome, continue to hold cabozantinib and 
monitor UPCR weekly. If UPCR decreases to < 1.5, restart 
cabozantinib at a reduced dose.  Continue monitoring UPCR 
once every week until two consecutive readings are < 1, then 
revert to UPCR monitoring frequency specified in the protocol.

6.9 
Guidelines for the Prevention of Hemorrhagic Events 
 
Hemorrhagic events have been reported with approved drugs that inhibit VEGF pathways as well 
as with cabozantinib.  As preventive measures, subjects should be evaluated for potential 
bleeding risk factors prior to initiating cabozantinib treatment and monitored for bleeding events 
with serial complete blood counts and physical examination while on study.  Risk factors for 
hemorrhagic events may include (but may not be limited to) the following: 
 
• Tumor lesions with cavitations or tumor lesions which invade, encase, or abut major blood 
vessels.  The anatomic location and characteristics of primary tumors or metastases as well as 
the medical history should be carefully reviewed in the selection of subjects for treatment 
with cabozantinib. 
• Recent or concurrent radiation to the thoracic cavity.  
• Active peptic ulcer disease, ulcerative colitis, and other inflammatory GI diseases. 
• Underlying medical conditions which affect normal hemostasis (e.g., deficiencies in clotting 
factors and/or platelet function, or thrombocytopenia). 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
41  
Version Date: February 17, 2017 
 
• Concomitant medication with anticoagulants or other drugs which affect normal hemostasis. 
• History of clinically significant hemoptysis. 
 
 
Cabozantinib should be discontinued in subjects with serious and life-threatening bleeding 
events or recent hemoptysis (≥0.5 teaspoon (2.5mL) of red blood).  Treatment with cabozantinib 
should be interrupted if less severe forms of clinically significant hemorrhage occur and may be 
restarted after the cause of hemorrhage has been identified and the risk of bleeding has subsided 
at a dose agreed to by the sponsor and the investigator.  Therapy of bleeding events should 
include supportive care and standard medical interventions.  
 
Furthermore, subjects who develop tumors abutting, encasing, or invading a major blood vessel 
or who develop cavitation of their pulmonary tumors while on study treatment must be 
discontinued from cabozantinib treatment. 
 
6.10 
Rectal and Perirectal Abscess 
 
Rectal and perirectal abscesses have been reported, sometimes in subjects with concurrent 
diarrhea. These should be treated with appropriate local care and antibiotic therapy. Cabozantinib 
should be held until adequate healing has taken place.  
 
6.11 
Guidelines for Prevention of GI Perforation/Fistula and Non-GI Fistula Formation 
 
GI perforation/fistula and Non-GI fistula formation have been reported with approved drugs that 
inhibit VEGF pathways as well as with cabozantinib. Carefully monitor for episodes of 
abdominal pain, especially in subjects with known risk factors for developing GI 
perforation/fistula or non-GI fistula, to allow for early diagnosis. Such risk factors include (but 
may not be limited to) the following: 
 
GI-perforation/fistula: 
 
• Intra-abdominal tumor/metastases invading GI mucosa.  
• Active peptic ulcer disease, inflammatory bowel disease, ulcerative colitis, diverticulitis, 
cholecystitis or symptomatic cholangitis, or appendicitis . 
• History of abdominal fistula, GI perforation, bowel obstruction, or intra-abdominal abscess 
• Prior GI surgery (particularly when associated with delayed or incomplete healing). 
Complete healing following abdominal surgery or resolution of intra-abdominal abscess must 
be confirmed prior to initiating treatment with cabozantinib. 
 
Additional risk factors include concurrent chronic use of steroid treatment or non-steroidal 
anti-inflammatory drugs.  Constipation indicative of bowel obstruction should be monitored and 
effectively managed.  
 
Non-GI fistula: 
 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
42  
Version Date: February 17, 2017 
 
• Radiation therapy has been identified as a possible predisposing risk factor for non-GI fistula 
formation in subjects undergoing treatment with drugs that inhibit VEGF pathways.  In 
addition, subjects who have undergone extensive surgery may be at increased risk of 
developing a fistula of the involved organs Non-GI fistula should be ruled out as appropriate 
in cases of onset of mucositis after start of therapy. 
  
Discontinue all study treatment in subjects who have been diagnosed with GI or non-GI 
perforation/fistula. 
 
6.12 
Wound Healing and Surgery 
 
VEGF inhibitors can cause wound healing complications and wound dehiscence which may 
occur even long after a wound has been considered healed. Therefore, surgical and traumatic 
wounds must have completely healed prior to starting cabozantinib treatment and be monitored 
for wound dehiscence or wound infection while the subject is being treated with cabozantinib.  
 
Treatment with cabozantinib must be interrupted for any wound healing complication which 
needs medical intervention. Treatment with cabozantinib can be resumed once wound healing 
has occurred unless otherwise prohibited in specific protocols. Cabozantinib should be 
discontinued in subjects with serious or chronic wound healing complications. 
 
The appropriate dose hold interval prior to elective surgery to reduce the risk for wound healing 
complications has not been determined. In general, cabozantinib should be stopped at least 
3 weeks (5 half-lives) prior to elective surgery.  
 
6.13 
Endocrine Disorders 
 
Prospective studies of markers of thyroid functions are currently ongoing in two single-agent 
studies to characterize the effects of cabozantinib on thyroid function. Preliminary data indicate 
that cabozantinib affects thyroid function tests (TFTs) in a high number of subjects (see 
Cabozantinib Investigator’s Brochure).  Routine monitoring of thyroid function and assessments 
for signs and symptoms associated with thyroid dysfunction is recommended for subjects treated 
with cabozantinib. Management of thyroid dysfunction (e.g., symptomatic hypothyroidism) 
should follow accepted clinical practice guidelines. 
 
Other endocrine disorders such as hypocalcemia and hyperglycemia, and associated laboratory 
changes, have been observed in less than 10% of subjects.  Monitoring with standard laboratory 
tests for endocrine disorders and clinical examination prior to initiation and during treatment 
with cabozantinib is required.  Cabozantinib should be discontinued in subjects with severe or 
life-threatening endocrine dysfunction. 
 
6.14 
Guidelines for Prevention of Osteonecrosis of the Jaw 
 
Osteonecrosis of the jaw (ONJ) has been reported with use of antiangiogenic drugs and 
bisphosphonates and denosumab in cancer patients.  Additional risk factors for ONJ have been 
identified such as use of corticosteroids, chemotherapy, local radiotherapy, poor oral hygiene, 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
43  
Version Date: February 17, 2017 
 
smoking, dental or orofacial surgery procedures, and cancer disease itself.  Cases of 
osteonecrosis have been reported in subjects treated with cabozantinib, the details of which are 
provided in the current version of Investigator’s Brochure.  As a preventive measure, invasive 
dental procedures should be avoided if possible in subjects who have previously been treated 
with or concomitantly receive bisphosphonates or denosumab. In cases where dental procedures 
are unavoidable, the risks and benefits of a dental procedure and the extent of the procedure as 
well as the risk of developing osteonecrosis of the jaw need to be considered when deciding on 
the duration of a temporary treatment interruption of cabozantinib.  If clinically possible, 
treatment with cabozantinib should be held for at least 2 weeks prior to a dental procedure and 
resumed after complete wound healing occurred. 
 
Subjects with any documented case of osteonecrosis should have study treatment interrupted, 
and appropriate clinical management should be initiated.  Re-initiation of study treatment must 
be discussed with and approved by the Sponsor on a case by case basis. 
 
6.15 
Guidelines for Management of Treatment-Emergent Corrected QT (QTc) 
Prolongation 
 
Treatment with cabozantinib has been associated with a mild prolongation of the QTc interval.  
Other factors which may contribute to QTc prolongation include 
• Treatment with other drugs associated with QTc prolongation (see 
http://www.qtdrugs.org). 
• Treatment with CyP 3A4 inhibitors (which may increase cabozantinib drug levels) 
• Electrolyte changes (hypokalemia, hypocalcemia, hypomagnesemia). 
• Medical conditions which can alter electrolyte status e.g., severe or prolonged diarrhea. 
 
Subjects having any of these additional risk factors while on cabozantinib must have ECGs 
performed approximately one week after the onset of these factors. 
 
If at any time on study there is an increase in QTc interval to an absolute value >500 msec, two 
additional ECGs should be performed within 30 minutes after the initial ECG with intervals not 
less than 3 minutes apart.  If the average QTcF from the three ECGs is >500 msec, study 
treatment must be withheld and the following actions should be taken: 
 
• Check electrolytes, especially potassium, magnesium and calcium.  Correct abnormalities 
as clinically indicated. 
• If possible, discontinue any QTc-prolonging concomitant medications. 
•  Repeat ECG triplets hourly until the average QTcF is ≤500 msec or otherwise 
determined by consultation with a cardiologist. 
 
The Sponsor should be notified immediately of any QTc prolongation event.  
 
Subjects with QTc prolongation and symptoms must be monitored closely until the QTc 
elevation has resolved.  Cardiology consultation is recommended for evaluation and subject

subject has been thoroughly evaluated, and further treatment has been agreed to by the Sponsor.  
If any additional study treatment is given (e.g., after correction of electrolyte abnormalities and 
normalization of QTcF), it will be at a reduced dose as agreed to by the investigator and the 
Sponsor. 
 
 
 
 
7. ADVERSE EVENTS REPORTING REQUIREMENTS 
 
7.1 
ADVERSE EVENT REPORTING FOR AN INVESTIGATIONAL AGENT 
   
7.1.1 Definition of Adverse Events (AE) 
 
An adverse event (AE) is any unfavorable and unintended sign (including 
an abnormal laboratory finding), symptom, or disease that occurs in a 
patient administered a medical treatment, whether the event is considered 
related or unrelated to the medical treatment.  
 
CTCAE term (AE description) and grade:  The descriptions and 
grading scales found in the CTEP Active Version of the NCI Common 
Terminology Criteria for Adverse Events (CTCAE) will be utilized for AE 
reporting.  The CTCAE version 4.0 is identified and located on the CTEP 
website at: 
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.ht
m.  All appropriate treatment areas should have access to a copy of the 
CTCAE version 4.0. 
 
The CTCAE Manual is also available on the NRG member web site 
(http://www.gog.org under MANUALS). 
 
7.1.2 Reporting Expedited Adverse Events 
 
Depending on the phase of the study, use of investigational agents, and 
role of the pharmaceutical sponsor, an expedited AE report may need to 
reach multiple destinations.  For patients participating on a NRG trial, all 
expedited AE reports should be submitted by using the CTEP automated 
system for expedited reporting (CTEP-AERS).  All CTEP-AERS 
submissions are reviewed by NRG before final submission to CTEP.  
Submitting a report through CTEP-AERS serves as notification to NRG, 
and satisfies the NRG requirements for expedited AE reporting.  All 
adverse reactions will be immediately directed to the Study Chair for 
further action. 
 
The requirement for timely reporting of AEs to the study sponsor is 
specified in the Statement of Investigator, Form FDA-1572.  In signing the 
FDA-1572, the investigator assumes the responsibility for reporting AEs 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
45  
Version Date: February 17, 2017 
 
to the NCI.  In compliance with FDA regulations, as contained in 21 CFR 
312.64, AEs should be reported by the investigator. 
 
 
7.1.3 
Late Phase 2 and Phase 3 Studies: Expedited Reporting Requirements for 
Adverse Events that Occur on Studies under an IND/IDE within 30 Days of the Last 
Administration of the Investigational Agent/Intervention1, 2 
FDA REPORTING REQUIREMENTS FOR SERIOUS ADVERSE EVENTS (21 CFR Part 312) 
NOTE:  Investigators MUST immediately report to the sponsor (NCI) ANY Serious Adverse Events, whether or not 
they are considered related to the investigational agent(s)/intervention (21 CFR 312.64) 
An adverse event is considered serious if it results in ANY of the following outcomes:   
1) 
Death 
2) 
A life-threatening adverse event  
3) 
An adverse event that results in inpatient hospitalization or prolongation of existing hospitalization for ≥ 24 
hours  
4) 
A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions  
5) 
A congenital anomaly/birth defect.  
6) 
Important Medical Events (IME) that may not result in death, be life threatening, or require hospitalization 
may be considered serious when, based upon 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. (FDA, 21 CFR 312.32; ICH E2A and ICH E6). 
 
ALL SERIOUS adverse events that meet the above criteria MUST be immediately reported to the NCI via AdEERS 
within the timeframes detailed in the table below.

NOTE:  Protocol specific exceptions to expedited reporting of serious adverse events are found in the Specific 
Protocol Exceptions to Expedited Reporting (SPEER) portion of the CAEPR 
Expedited AE reporting timelines are defined as: 
o 
“24-Hour; 5 Calendar Days” - The AE must initially be reported via AdEERS within 24 hours of learning of 
the AE, followed by a complete expedited report within 5 calendar days of the initial 24-hour report. 
o 
“10 Calendar Days” - A complete expedited report on the AE must be submitted within 10 calendar days of 
learning of the AE. 
1Serious adverse events that occur more than 30 days after the last administration of investigational 
agent/intervention and have an attribution of possible, probable, or definite require reporting as follows:  
Expedited 24-hour notification followed by complete report within 5 calendar days for: 
• 
All Grade 4, and Grade 5 AEs 
Expedited 10 calendar day reports for: 
• 
Grade 2 adverse events resulting in hospitalization or prolongation of hospitalization  
• 
Grade 3 adverse events 
2For studies using PET or SPECT IND agents, the AE reporting period is limited to 10 radioactive half-lives, 
rounded UP to the nearest whole day, after the agent/intervention was last administered.  Footnote “1” above 
applies after this reporting period. 
Effective Date:  May 5, 2011 
Note:  All deaths on study require both routine and expedited reporting regardless  
of causality.   
Attribution to treatment or other cause must be provided.

• 
Expedited AE reporting timelines defined: 
➢ “24 hours; 3 calendar days” – The investigator must initially report the AE via CTEP-AERS within 24 
hours of learning of the event followed by a complete CTEP-AERS report within 3 calendar days of 
the initial 24-hour report. 
➢ “7 calendar days” - A complete CTEP-AERS report on the AE must be submitted within  
7 calendar days of the investigator learning of the event.  
 
• 
Any medical event equivalent to CTCAE grade 3, 4, or 5 that precipitates hospitalization (or prolongation 
of existing hospitalization) must be reported regardless of attribution and designation as expected or 
unexpected with the exception of any events identified as protocol-
specific expedited adverse event reporting exclusions. 
 
• 
Any event that results in persistent or significant disabilities/incapacities, congenital anomalies, or birth 
defects must be reported via CTEP-AERS if the event occurs following treatment with an agent under a 
CTEP IND. 
 
• 
Use the NCI protocol number and the protocol-specific patient ID provided during trial registration on all 
reports. 
Additional Instructions or Exceptions to CTEP-AERS Expedited Reporting Requirements for Phase 2 and 3 Trials 
Utilizing an Agent under a CTEP-IND: 
 
• 
Grades 2-4 myelosuppression (including neutropenia, anemia, and thrombocytopenia) that do not require 
hospitalization are exempt from expedited reporting 
 
7.1.4 Procedures for Expedited Adverse Event Reporting  
 
7.1.4.1 CTEP-AERS Expedited Reports: Expedited reports are to be 
submitted using CTEP-AERS available at http://ctep.cancer.gov. 
The CTEP, NCI Guidelines: Adverse Event Reporting 
Requirements for expedited adverse event reporting requirements 
are also available at this site.  
 
AML/MDS events must be reported via CTEP-AERS (in addition 
to your routine AE reporting mechanisms). In CTCAE v4.0, the 
event(s) may be reported as either: 1) Leukemia secondary to 
oncology chemotherapy, 2) Myelodysplastic syndrome, or 3) 
Treatment related secondary malignancy. 
 
 
Any malignancy possibly related to cancer treatment (including 
AML/MDS) should also be reported via the routine reporting 
mechanisms outlined in each protocol. 
 
 In the rare event when Internet connectivity is disrupted a 24-hour 
notification is to be made to NCI by telephone at: 301-897-7497.  
An electronic report MUST be submitted immediately upon re-
establishment of internet connection. Please note that all paper 
CTEP-AERS forms have been removed from the CTEP website 
and will NO LONGER be accepted. 
 
For the purposes of expedited reporting of adverse events to CTEP,

unexpected events are those not listed in the Specific Protocol 
Exceptions to Expedited Reporting (SPEER). The SPEER is a 
subset of AEs within the Comprehensive Adverse Event and 
Potential Risks List (CAEPR). This list of events is based on 
CTEP’s clinical experience with this agent and defines “expected” 
Grade 2 and 3 AEs not requiring hospitalization as exempt from 
expedited reporting. The CAEPR is a complete list of reported 
and/or potential AEs associated with an agent under a CTEP IND. 
For questions or comments regarding the SPEER or CAEPR, 
please contact the CTEP-AERS MD Help Desk at CTEP-
AERSmd@tech-res.com. 
 
Secondary Malignancy:  
 
A secondary malignancy is a cancer caused by treatment for a 
previous malignancy (e.g., treatment with investigational 
agent/intervention, radiation or chemotherapy). A secondary 
malignancy is not considered a metastasis of the initial neoplasm.  
 
CTEP requires all secondary malignancies that occur following 
treatment with an agent under an NCI IND/IDE be reported via 
AdEERS. Three options are available to describe the event:  
• 
Leukemia secondary to oncology chemotherapy (e.g., acute 
myelocytic leukemia [AML])  
• 
Myelodysplastic syndrome (MDS)  
• 
Treatment-related secondary malignancy  
 
Any malignancy possibly related to cancer treatment (including 
AML/MDS) should also be reported via the routine reporting 
mechanisms outlined in each protocol.  
 
Second Malignancy:  
 
A second malignancy is one unrelated to the treatment of a prior 
malignancy (and is NOT a metastasis from the initial malignancy).  
Second malignancies require ONLY routine reporting via CDUS 
unless otherwise specified. “ 
 
 
 
 
 
7.1.5 Routine Adverse Event Reporting  
 
For studies using investigational agents, the NRG Statistical and Data 
Center (SDC) routinely reports adverse events electronically to the CTEP 
Clinical Data Update System (CDUS Version 3.0).  The SDC submits this 
data quarterly.  The AEs reported through CTEP-AERS will also be 
included with the quarterly CDUS data submissions.

• All patients have signed an appropriate consent form and HIPAA 
authorization form (if applicable).  
 
Access requirements for OPEN: 
• See beginning of Section 8 for information on obtaining a CTEP-IAM account.  
• To perform registrations, the site user must have been assigned the 'Registrar' role 
on the relevant Group or CTSU roster.  
• To perform registrations on protocols for which you are a member of the NRG, 
you must have an equivalent 'Registrar' role on the NRG roster.  Role assignments 
are handled through the Groups in which you are a member.  
• To perform registrations to trials accessed via the CTSU mechanism (i.e., non-
Lead Group registrations) you must have the role of Registrar on the CTSU roster. 
Site and/or Data Administrators can manage CTSU roster roles via the new Site 
Roles maintenance feature under RSS on the CTSU members' web site. This will 
allow them to assign staff the "Registrar" role. 
 
The OPEN system will provide the site with a printable confirmation of registration and 
treatment information.  Please print this confirmation for your records. [Add if 
applicable: Additionally, a transmittal form to be used when faxing the signed consent 
form to the NRG Biostatistical Center will be provided.  If it is necessary to reprint the 
randomization confirmation or the transmittal form, they can be reprinted through 
Coordinator Online via the View a Patient Entry Report under Patient Entry.] 
 
Further instructional information is provided on the OPEN tab located on the CTSU 
members' web site at https://www.ctsu.org or at https://open.ctsu.org. For any additional

missed dose within 12 hours of the next dose. 
 
9.1.8 Potential Drug Interactions:  
CYP450 isozymes: 
In vitro, XL184 is a substrate of CYP3A4 and a weak substrate of CYP2C9. Co-administration of 
ketoconazole, a strong inhibitor of CYP3A4, increases XL184 AUC (37%) and rifampin, a strong 
inducer of CYP3A4, reduces XL184 AUC (77%). Therefore, avoid chronic use of strong 
CYP3A4 inducers such as rifampin, dexamethasone, phenytoin, carbamazepine, rifabutin, 
rifampentin, phenobarbital, and St. John’s Wort while taking XL184. Avoid chronic use of strong 
CYP3A4 inhibitors such as ketoconazole, itraconazole, clarithromycin, indinavir, nefazodone, 
nelfinavir, and ritonavir. Use alternative medications. 
 
[Note: Use caution when discontinuing medication that is a strong inducer of CYP3A4 in patients 
who has been on a stable dose of XL184, as this could significantly increase the exposure to 
XL184.] 
 
XL184 is a noncompetitive inhibitor of CYP2C8 (Kiapp = 4.6 μM), a mixed-type inhibitor of both 
CYP2C9 (Kiapp = 10.4 μM) and CYP2C19 (Kiapp = 28.8 μM), and a weak competitive inhibitor of 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
53  
Version Date: February 17, 2017 
 
CYP3A4 (estimated Kiapp = 282 μM) in human liver microsomal (HLM). IC50 values >20 μM 
were observed for CYP1A2, CYP2D6, and CYP3A4 isozymes. XL184 is an inducer of CYP1A1 
mRNA in human hepatocyte incubations, 
 
Avoid grapefruit/ grapefruit juice and Seville oranges while participating in this trial. 
 
P-glycoprotein/ MRP2: 
In vitro data indicate that XL184 is unlikely to be a substrate but may be an inhibitor of P-
glycoprotein transport activity (IC50 = 7.0 μM). Co-administration of XL184 with a P-gp substrate 
may result in an increase in P-gp substrate plasma concentration. Therefore, use caution when 
administering XL-184 with drugs known to be P-gp substrates (e.g., fexofenadine, aliskiren, 
ambrisentan, digoxin, colchicine, maraviroc, posaconazole, tolvaptan, etc.). In an in vitro assay, 
XL184 has shown to be a substrate of drug transporter MRP2, which may result in an increase 
plasma concentration of XL184 when administered with an inhibitor of MRP2. Use caution and 
monitor adverse events when administering XL184 with MRP2 inhibitors such as cyclosporine, 
delavirine, efavirenz, emtricitabine. 
 
Protein bound: 
XL184 is highly protein bound (≥ 99.9%). Use caution when coadministering XL184 with 
medications that are highly protein-bound (e.g., diazepam, furosemide, dicloxacillin, and 
propranolol). Avoid administration of warfarin with XL184 as warfarin is highly protein-bound 
and has a very narrow therapeutic index. 
 
Antacids, H2-blockers, PPIs: 
Co-administration of gastric pH modifying drugs such as PPI, H2-blockers or antacids has no 
clinically-relevant effect on XL184 plasma PK in healthy volunteers; thus, concomitant use of 
these drugs with XL184 is allowed. 
 
QTc prolongation: 
Use caution when administering XL184 in patients with QT prolongation risk, a history of QT 
interval prolongation, or who are receiving antiarrhythmic drugs. Concomitant use of strong 
CYP3A4 inhibitors should be avoided as it may increase XL184 plasma concentrations. Refer to 
the protocol for QTcF criteria. 
 
9.1.9 Potential Food Effect 
The effect of food on the bioavailability of cabozantinib was evaluated in healthy adult 
subjects in a Phase 1, open-label, randomized, single-dose, two-treatment, two-way 
crossover study (Study XL184-004). Based on the preliminary PK data, a high fat meal did 
not appear to alter the terminal t1/2 but significantly increased the median tmax to 6 hours 
from 4 hours (fasted). The high fat meal also significantly increased both the cabozantinib 
Cmax and AUC values by 41% and 57%, respectively. Based on this result, cabozantinib 
should be taken on an empty stomach (fasting is required 2 hours before and 1 hour after 
each cabozantinib dose). 
 
9.1.10 Patient Care Implications:   Do not take grapefruit/ grapefruit juice or Seville oranges 
while participating in this trial.  Inform physician and study healthcare team about current 
medications including over the counter drugs, herbals, or natural medicines.  Refer to the 
protocol for management of adverse events

9.1.11 Availability 
 
Cabozantinib (XL184) is an investigational agent supplied to investigators by the 
Division of Cancer Treatment and Diagnosis (DCTD), NCI. 
 
Cabozantinib (XL184) is provided to the NCI under a Collaborative Agreement between 
the Pharmaceutical Collaborator and the DCTD, NCI (see Appendix I). 
 
9.1.12 Agent Ordering and Agent Accountability (09/08/15) 
 
NCI supplied agents may be requested by the Principal Investigator (or their authorized 
designee) at each participating institution.  Pharmaceutical Management Branch (PMB) 
policy requires that agent be shipped directly to the institution where the patient is to be 
treated.  PMB does not permit the transfer of agents between institutions (unless prior 
approval from PMB is obtained.)  The CTEP assigned protocol number must be used for 
ordering all CTEP supplied investigational agents.  The responsible investigator at each 
participating institution must be registered with CTEP, DCTD through an annual 
submission of FDA form 1572 (Statement of Investigator), Curriculum Vitae, 
Supplemental Investigator Data Form (IDF), and Financial Disclosure Form (FDF).  If 
there are several participating investigators at one institution, CTEP supplied 
investigational agents for the study should be ordered under the name of one lead 
investigator at that institution. 
 
Active CTEP-registered investigators and investigator-designated shipping designees and

9.1.13 Comprehensive Adverse Events and Potential Risks list (CAEPR) 
for 
XL184 (Cabozantinib s-malate, NSC 761968) 
 
The Comprehensive Adverse Events and Potential Risks list (CAEPR) provides a single list of reported 
and/or potential adverse events (AE) associated with an agent using a uniform presentation of events by 
body system. In addition to the comprehensive list, a subset, the Specific Protocol Exceptions to 
Expedited Reporting (SPEER), appears in a separate column and is identified with bold and italicized 
text. This subset of AEs (SPEER) is a list of events that are protocol specific exceptions to expedited

reporting to NCI (except as noted below).  Refer to the 'CTEP, NCI Guidelines: Adverse Event Reporting 
Requirements' http://ctep.cancer.gov/protocolDevelopment/electronic_applications/docs/aeguidelines.pdf 
for further clarification. Frequency is provided based on 2438 patients. Below is the CAEPR for XL184 
(Cabozantinib s-malate). 
NOTE: Report AEs on the SPEER ONLY IF they exceed the grade noted in parentheses next to the 
AE in the SPEER.  If this CAEPR is part of a combination protocol using multiple investigational 
agents and has an AE listed on different SPEERs, use the lower of the grades to determine if 
expedited reporting is required.

PATHOLOGY   
 
Patients must have recurrent or, progressive clear cell ovarian cancer not solely based on CA-
125. A retrospective review of all patients entered will be performed to confirm clear cell 
histology. Primary tumors must be at least 50% clear cell histomorphology in order to be 
eligible or have a histologically documented recurrence with at least 50% clear cell 
histomorphology.

Stained pathology slides are required for central review by the NRG Pathology Committee to 
confirm eligibility for the protocol.  At least one representative H&E stained slide (or slides) 
demonstrating primary site, histologic cell type, and grade, and one H&E stained slide 
showing the most advanced stage of disease will be required. When submitting pathology 
material to the NRG Statistics and Data Center individual slides must be labeled with NRG 
Patient ID, patient initials and the surgical / pathology accession number (e.g., S08-2355) and 
block identifier (e.g., A6).  Do not label the slides with disease site (e.g., right ovary) or 
procedure date.  Pack the labeled slides into plastic slide cassette(s).  Tape plastic slide 
cassettes shut and wrap in bubble wrap or another type of padded material prior to shipping.  
Please include the NRG Patient ID, patient initials, and protocol number on all pages of the 
pathology report and black out the patient’s name.  Ship stained pathology slides and the 
official pathology report in your own shipping containing using postal mail at your own 
expense directly to the Pathology Materials Coordinator at the NRG Statistics and Data 
Center, Roswell Park Cancer Institute, Research Studies Center, Carlton and Elm 
Streets, Buffalo, New York, 14263; phone (716) 845-5702.Please see section 13.2 for

Summary of Data Submission 
 
Adverse event data collection and reporting, which are required as part of every clinical 
trial, are done to ensure the safety of patients enrolled in the studies as well as those who 
will enroll in future studies using similar agents. Adverse events are reported in a routine 
manner at scheduled times during the trial using Medidata Rave®. Additionally, certain 
adverse events must be reported in an expedited manner for more timely monitoring of 
patient safety and care. See Sections 7.1.4 and 7.1.5 for information about expedited and 
routine reporting.

13. STATISTICAL CONSIDERATIONS 
13.1 
Study Design 
The primary objective of this study is to assess the anti- tumor activity of cabozantinib 
(XL184) in women with persistent or recurrent clear cell ovarian cancer. The primary 
measures of efficacy will be objective response and whether the patient survived 
progression-free for at least 6 months. 
 
This is a single-arm, Phase II clinical trial that will use a flexible, bivariate, three-stage 
design.

13.1.1 Stratification 
This is a single-arm, trial with no randomization and thus no stratification. 
 
13.1.2 Randomization 
This is a single-arm, trial with no randomization. 
 
13.1.3 Total Accrual 
If the trial enters all three stages, the total accrual target will be 31 patients but will be 
allowed to range from 27 to 34 (due to the difficulty in accruing precise numbers of 
patients in a multicenter trial). 
 
13.1.4 Justification of Design:  
The biologic mechanism of the study agent is expected to impede the growth of tumors 
already present and inhibit the development of new metastases.  Therefore, the endpoint 
includes progression-free survival at 6 months, which is capable of detecting stabilization 
of disease.  In addition, there is also interest in objective tumor response as a primary 
measure of efficacy.  So the design of the study will use both endpoints to formally draw 
conclusions about the activity of the drug.  In particular, if either endpoint indicates 
activity, the drug will be considered clinically interesting and worthy of further 
investigation. 
 
13.2 
Study Endpoints 
Primary endpoints: 
• Progression-free survival at six months 
• Complete or partial objective tumor response 
 
Secondary endpoints: 
• Nature, frequency and maximum degree of toxicity as assessed by CTCAE v4 
• Progression-free survival 
• Overall survival. 
 
 
13.3 
Primary Objectives Study Design 
13.3.1 Primary Hypothesis and Endpoints 
The primary hypothesis of this study tests the proportion of patients with objective tumor 
response (complete or partial) (πr) and the proportion of patients surviving progression 
free for at least six months (πs).  Based on the historical data shown below, the null 
hypothesis is that the proportion of patients with objective tumor response will be ≤10% 
and the proportion of patients surviving progression free for at least six months (πs) will 
be ≤15%, i.e.,: 
 
H0: πr ≤ 0.10 and πr ≤ 0.15. 
 
The alternative hypothesis is the complement of the null parameter space, and the study is 
powered to detect the following points in the alternative space: πr = .3 or πs = .4.

The primary analysis will include all eligible patients who receive study drug. 
 
The guiding principle in selecting the design for this study is to limit the number of 
patients treated with clinically ineffective therapies but to estimate efficacy with 
reasonable precision for those agents that are clinically active.  Strict adherence to a 
planned sample size is not practical because the accrual is complicated by the logistics of 
managing a multi-center phase II study.  Instead, a flexible sample size will be used in 
which once the targeted sample size is attained, those patients who have already been 
approached will be permitted to register. 
 
Historical Data and Design Parameters 
The design parameters for this study arise from considering the results of three series of 
protocols: GOG-0126, GOG-0146, and GOG-0170.  The patients entered on GOG-0126 
were required to have platinum resistant disease (i.e. a platinum free interval of less than 
6 months) while the patients entered on GOG-0146 were required to be GOG platinum 
sensitive (i.e. a platinum-free interval between 6 and 12 months).  Both of these patient 
populations were allowed in GOG-0170 and will be allowed to enter the current protocol.  
Selected GOG protocols from these series are listed in Table 13.1 and were selected for 
historical controls because the population is similar to the current protocol and the agents 
investigated in the selected protocols were deemed to have minimal activity.

13.3.2 Definitions of Primary Endpoints and How These Will Be Analyzed 
To evaluate the hypothesis stated above, we will utilize a modification of the bivariate 
two-stage design of Sill, et al (2012), which uses the numbers of patients progression-free 
at 6 months and the number with objective responses to make inferences about the 
efficacy of the study drug. We will add an additional stage to the study—preceding the 
Sill design.  In the first stage, if all patients have increasing disease (progression) at their 
first scan (which will be done after 2 cycles or 8 weeks), the trial will be stopped, and the 
agent will be not considered worthy of further investigation in this patient population.  
The trial will be suspended for this first stage decision; however, if at any point, any of 
these patients do not have increasing disease, it would not be necessary to suspend the 
trial.   
 
If the trial enters the second stage and third stage, the following decision rules will be 
applied where 
• Xr(1) is the number of patients with objective tumor responses (partial or complete) 
within four months of starting treatment in stage 1, 
• Xs(1) is the number of patients progression-free at 6 months after stage 1, 
• Xr(2) is the number of patients with objective tumor responses after stage 2, 
• Xs(2) is the number of patients progression-free at 6 months after stage 2, 
• Xr is the cumulative number of patients with objective tumor responses after 
stage 3, 
• Xs is the cumulative number of patients progression-free at 6 months after stage 3, 
• Cr(1) is the critical value for Xr(1), 
• Cr(2) is the critical value for Xr(2), 
• Cs(2) is the critical value for Xs(2), 
• Cr is the critical value for Xr, and 
• Cs is the critical value for Xs. 
Decision Rules:  
1) If Xr(1) > Cr(1) after the first stage, then the study will open to a second stage of accrual 
to further evaluate the activity of the drug, 
a. or if Xs(1) > Cs(2), the trial will open to the third stage of accrual (because the 
number of patients with PFS≥6 months in the first stage will be greater than that 
required in the second stage). 
2) If either Xr(2) > Cr(2) or Xs(2) > Cs(2) after the second stage, then the study will open to a 
third stage of accrual to further evaluate the activity of the drug.   
3) If either Xr > Cr or Xs > Cs after the third stage and clinical judgment indicates, then 
the agent will be deemed clinically interesting and worthy of further investigation.

13.3.3 Sample Size and Power Calculations 
The targeted accrual for the first stage will be 12 eligible and treated patients but will be 
permitted to range from 10 to 14. If all patients have increasing disease on their first scan, 
the trial will be terminated for futility.   The cumulative targeted accrual for the second 
stage will be 19 eligible and evaluable patients but permitted to range from 15 to 22 for 
administrative reasons.  The cumulative targeted accrual for the third stage will be 31 
eligible and evaluable patients.  Critical values for each stage are provided in Table 13.2, 
Table 13.3, and Table 13.4, respectively. 
We acknowledge that a three-stage trial may lengthen the trial beyond what is normally 
expected; therefore, we will follow the following plan for the first stage.  After eight 
patients have been followed for response for four months (which is required for the Xr(1) 
endpoint), if no responses have been seen, we will suspend the trial; otherwise, we will 
continue to stage 2.  If the trial is suspended, we will then follow any additional patients 
for the response endpoint; given the anticipated accrual rate of 1/month, this should be 
approximately four or less.  If no responses are seen, the trial will end. 
The operating characteristics of each stage’s decision rules are provided in Table 13.5 
and Table 13.6 under the assumption of independence of response and PFS and under an 
assumption of a high association between response and PFS, respectively.  To assess the 
operating characteristics when the two primary endpoints are not independent, the 
probability calculations (carried out as outlined above) were done with the assumption 
that the joint probability (11) of response and PFS at 6 months is equal to 0.90 ∙ min{πr, 
πs}, which would carry a fairly high degree of association.

13.5 
Accrual Considerations 
13.5.1 Accrual Rate 
We expect to accrue approximately one patient per month.  This is based on the accrual 
to study GOG-0254, which accrued 35 patients over 34 months of active accrual in the 
same patient population. 
 
13.5.2 Accrual Goal 
 
Ten patients are required for the first stage, a cumulative target of 19 (allowable range 
15-22) in the second stage, and a cumulative target of 31 (allowable range 27-34) in the 
third stage. 
 
13.5.3 Study Duration 
 
Approximately sixteen months are expected to be required for the first stage, ten months 
for the second stage, and twelve months for the third stage. 
 
13.5.4 Estimated Duration for Completion of Primary Endpoint:  
 
Completion of the primary endpoints is expected approximately 52 months after 
activation. 
 
13.6 
Dose Level Guidelines 
 
Not applicable. 
 
13.7 
Secondary or Exploratory Elements (including correlative science aims) 
If there are secondary or exploratory aims, they must be addressed in the Statistical 
Considerations section. 
 
13.7.1 Secondary Hypotheses and Endpoints:  
 
Below are the secondary objectives and endpoints. These are focused on estimation and 
description; there are no associated hypotheses. 
 
Objective: To determine the nature, frequency and maximum degree of toxicity as 
assessed by CTCAE v4 for cabozantinib (XL184) 
Endpoint: Adverse events based on CTC AE v 4. 
 
Objective: To determine the PFS and OS for patients with persistent or recurrent clear 
cell ovarian cancer treated with cabozantinib (XL184). 
Endpoints: Progression-free Survival and Overall Survival 
 
13.7.2 Definitions of Secondary Endpoints and How These Will Be Analyzed 
Adverse events are based on CTC AE v 4.  Events will be tabulated using maximum 
grade for each AE term regardless of attribution to study drug. 
 
Overall survival and PFS of patients on this study will be characterized graphically and 
using descriptive statistics such as median survival based on Kaplan-Meier estimates.

As there are no hypotheses for the secondary endpoints, no power calculations are done. 
 
13.7.5 Expected Sample Size or Patient Cohorts: 
Not applicable. 
 
13.7.6 Data and Safety Monitoring (09/08/15) 
Data sheets from studies on this protocol will be reviewed before each semi-annual 
meeting and will also be reviewed by the Study Chairperson in conjunction with the NRG 
Statistics and Data Management Center (SDMC). In some instances, because of 
unexpectedly severe toxicity, the NRG SDMC may elect, after consultation with the 
Study Chairperson and the Medical Oncology Committee, to recommend early closure of 
a study.  
 
The frequency and severity of all toxicities are tabulated from submitted case report 
forms and summarized for review by the study chairperson, Gynecologic Rare Tumor 
Committee, and NRG Safety Review Committee (SRC) in conjunction with each semi-
annual NRG meeting. For studies sponsored by CTEP of the National Cancer Institute 
(NCI), standardized toxicity reports are also submitted to the drug and disease monitors at 
the Investigational Drug Branch (IDB) and Clinical Investigation Branch (CIB). As this 
is a multi-stage multi-institutional phase II protocol, the initial overall review of toxicity 
is usually performed after completion of the first stage of accrual, at which point accrual 
is generally suspended pending formal analysis of response.  
 
All serious and/or unexpected events are communicated to the Study Chair, sponsor, and 
regulatory agencies as mandated in the protocol. These reports are reviewed by the Study 
Chair (or designated co-chair) within two working days for consideration of investigator 
notification, amendment, or immediate study suspension. All participating institutions 
will then receive notification of the toxicities and reason for study suspension. Under 
these circumstances, accrual cannot be re-activated until the study is reviewed by the 
NRG SRC. However, patients currently receiving treatment may continue to receive 
treatment in accordance with protocol guidelines at the discretion of their physicians, 
unless directed otherwise.

15. EVALUATION CRITERIA   
 
15.1 
Antitumor Effect – Solid Tumors 
 
Response and progression will be evaluated in this study using the new 
international criteria proposed by the revised Response Evaluation Criteria in 
Solid Tumors (RECIST) guideline (version 1.1) [Eur J Ca 45:228-247, 2009].  
Changes in the largest diameter (unidimensional measurement) of the tumor 
lesions and the shortest diameter in the case of malignant lymph nodes are used in 
the RECIST criteria. 
 
15.1.1 Definitions 
 
Evaluable for toxicity.  All patients will be evaluable for toxicity from the 
time of their first treatment on study. 
 
Evaluable for objective response.  Only those patients who have 
measurable disease present at baseline, have received at least one cycle of 
therapy, and have had their disease re-evaluated will be considered 
evaluable for response.  These patients will have their response classified 
according to the definitions stated below.  (Note:  Patients who exhibit 
objective disease progression prior to the end of cycle 1 will also be 
considered evaluable.) 
 
Evaluable Non-Target Disease Response.  Patients who have lesions 
present at baseline that are evaluable but do not meet the definitions of 
measurable disease, have received at least one cycle of therapy, and have 
had their disease re-evaluated will be considered evaluable for non-target 
disease.  The response assessment is based on the presence, absence, or 
unequivocal progression of the lesions.

15.1.2 Disease Parameters 
 
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 by chest x-ray, as >10 mm with CT scan, or >10 mm 
with calipers by clinical exam.  All tumor measurements must be recorded 
in millimeters (or decimal fractions of centimeters). 
 
Note:  Tumor lesions that are situated in a previously irradiated area will 
not be considered measurable unless progression is documented or a 
biopsy is obtained to confirm persistence at least 90 days following 
completion of radiation therapy. Thus, a confirmed biopsy in an irradiated 
area at a date longer than 90 days post-completion of radiation can be 
considered a target lesion to assess progression and response. 
 
Malignant lymph nodes.  To be considered pathologically enlarged and 
measurable, a lymph node must be >15 mm in short axis when assessed by 
CT scan (CT scan slice thickness recommended to be no greater than 5 
mm).  At baseline and in follow-up, only the short axis will be measured 
and followed. 
 
Non-measurable disease.  All other lesions (or sites of disease), including 
small lesions (longest diameter <10 mm or pathological lymph nodes with 
≥ 10 to <15 mm short axis), are considered non-measurable disease.  Bone 
lesions, leptomeningeal disease, ascites, pleural/pericardial effusions, 
lymphangitis cutis/pulmonitis, inflammatory breast disease, and 
abdominal masses (not followed by CT or MRI), are considered as non-
measurable. 
 
Note:  Cystic lesions that meet the criteria for radiographically defined 
simple cysts should not be considered as malignant lesions (neither 
measurable nor non-measurable) since they are, by definition, simple 
cysts. 
 
‘Cystic lesions’ thought to represent cystic metastases can be considered 
as measurable lesions, if they meet the definition of measurability 
described above. However, if non-cystic lesions are present in the same 
patient, these are preferred for selection as target lesions. 
 
Target lesions.  All measurable lesions up to a maximum of 2 lesions per 
organ and 5 lesions in total, representative of all involved organs, 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), be representative of all involved organs, but in 
addition should be those that lend themselves to reproducible repeated

measurements.  It may be the case that, on occasion, the largest lesion 
does not lend itself to reproducible measurement in which circumstance 
the next largest lesion which can be measured reproducibly should be 
selected.  A sum of the diameters (longest for non-nodal lesions, short axis 
for nodal lesions) for all target lesions will be calculated and reported as 
the baseline sum diameters.  If lymph nodes are to be included in the sum, 
then only the short axis is added into the sum.  The baseline sum diameters 
will be used as reference to further characterize any objective tumor 
regression in the measurable dimension of the disease. 
 
Non-target lesions.  All other lesions (or sites of disease) including any 
measurable lesions over and above the 5 target lesions should be identified 
as non-target lesions and should also be recorded at baseline.  
Measurements of these lesions are not required, but the presence, absence, 
or in rare cases unequivocal progression of each should be noted 
throughout follow-up.  
 
 
15.1.3 Methods 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. 
 
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 unless the lesion(s) being followed cannot be imaged but are 
assessable by clinical exam. 
 
Clinical lesions: Clinical lesions will only be considered measurable when they 
are superficial (e.g., skin nodules and palpable lymph nodes) and 10 mm 
diameter as assessed using calipers (e.g., skin nodules).  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: This guideline has defined measurability of lesions on 
CT scan based on the assumption that CT slice thickness is 5 mm or less.  If CT 
scans have slice thickness greater than 5 mm, the minimum size for a measurable 
lesion should be twice the slice thickness.  MRI is also acceptable in certain 
situations (e.g. for body scans), but NOT lung.

Use of MRI remains a complex issue.  MRI has excellent contrast, spatial, and 
temporal resolution; however, there are many image acquisition variables 
involved in MRI, which greatly impact image quality, lesion conspicuity, and 
measurement.  Furthermore, the availability of MRI is variable globally.  As with 
CT, if an MRI is performed, the technical specifications of the scanning 
sequences used should be optimized for the evaluation of the type and site of 
disease.  Furthermore, as with CT, the modality used at follow-up should be the 
same as was used at baseline and the lesions should be measured/assessed on the 
same pulse sequence.  It is beyond the scope of the RECIST guidelines to 
prescribe specific MRI pulse sequence parameters for all scanners, body parts, 
and diseases.  Ideally, the same type of scanner should be used and the image 
acquisition protocol should be followed as closely as possible to prior scans.  
Body scans should be performed with breath-hold scanning techniques, if 
possible. 
 
PET-CT: At present, the low dose or attenuation correction CT portion of a 
combined PET-CT is not always of optimal diagnostic CT quality for use with 
RECIST measurements.  PET-CT scans are not always done with oral and IV 
contrast.  In addition, the PET portion of the CT introduces additional data which 
may bias an investigator if it is not routinely or serially performed.  For these 
reasons, the GOG will not allow PET-CT use for RECIST 1.1 response criteria. 
 
Ultrasound:  Ultrasound is not useful in assessment of lesion size and should not 
be used as a method of measurement.  Ultrasound examinations cannot be 
reproduced in their entirety for independent review at a later date and, because 
they are operator dependent, it cannot be guaranteed that the same technique and 
measurements will be taken from one assessment to the next.  If new lesions are 
identified by ultrasound in the course of the study, confirmation by CT or MRI is 
advised.  If there is concern about radiation exposure at CT, MRI may be used 
instead of CT in selected instances. 
 
Endoscopy, Laparoscopy: The utilization of these techniques for objective 
tumor evaluation is not advised.  However, such techniques may be useful 
to confirm complete pathological response when biopsies are obtained or 
to determine relapse in trials where recurrence following complete 
response (CR) or surgical resection is an endpoint. 
 
CA125 (Ovarian, fallopian tube and primary peritoneal cancer trials): 
CA125 alone cannot be used to assess response.  If CA125 is initially 
above the upper normal limit, it must normalize for a patient to be 
considered in complete clinical response.  Specific guidelines for CA-125 
response (in recurrent ovarian cancer) have been published [JNCI 96:487-
488, 2004].  In addition, the Gynecologic Cancer Intergroup has 
developed CA-125 progression criteria which are to be integrated with 
objective tumor assessment for use in first-line trials in ovarian cancer

[JNCI 92:1534-1535, 2000]. 
 
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). 
 
 
 
The cytological confirmation of the neoplastic origin of any effusion that appears or worsens 
during treatment when the measurable tumor has met criteria for response or stable disease is 
mandatory to differentiate between response or stable disease (an effusion may be a side effect of the 
treatment) and progressive disease. 
 
 
 
 
15.1.4 Response Criteria 
 
15.1.4.1 
Evaluation of Target Lesions 
 
Complete Response (CR): Disappearance of all target lesions.  
Any pathological lymph nodes (whether target or non-target) 
must have reduction in short axis to <10 mm. 
 
 
 
 
 
 
 
 
Partial Response (PR): At least a 30% decrease in the sum of 
the diameters of target lesions, taking as reference the baseline 
sum diameters. 
 
Progressive Disease (PD): At least a 20% increase in the sum 
of the diameters of target lesions, taking as reference the 
smallest sum on study (this includes the baseline sum if that is 
the smallest on study).  In addition to the relative increase of 
20%, the sum must also demonstrate an absolute increase of at 
least 5 mm.  (Note:  the appearance of one or more new lesions 
is also considered progressions). 
 
Stable Disease (SD): Neither sufficient shrinkage to qualify for 
PR nor sufficient increase to qualify for PD, taking as reference 
the smallest sum diameters while on study. 
 
15.1.4.2 
Evaluation of Non-Target Lesions 
 
Complete Response (CR): Disappearance of all non-target 
lesions and normalization of tumor marker level.  All lymph 
nodes must be non-pathological in size (<10 mm short axis). 
 
Note:  If CA125 is initially above the upper normal limit, it 
must normalize for a patient to be considered in complete 
clinical response. 
 


NCI Protocol #:NRG-GY001 
Version Date: February 17, 2017 
 
NRG-GY001 
77  
Version Date: February 17, 2017 
 
Non-CR/Non-PD: Persistence of one or more non-target 
lesion(s) and/or maintenance of CA125 level above the normal 
limits. 
 
Progressive Disease (PD): Appearance of one or more new 
lesions and/or unequivocal progression of existing non-target 
lesions.  Unequivocal progression should not normally trump 
target lesion status.  It must be representative of overall disease 
status change, not a single lesion increase. 
 
Although a clear progression of “non-target” lesions only is 
exceptional, the opinion of the treating physician should 
prevail in such circumstances, and the progression status 
should be confirmed at a later time by the review panel (or 
Principal Investigator). 
  
15.1.4.3 
Progression Based on Serum CA-125 
 
1. Patients with elevated CA-125 pretreatment and 
normalization of CA-125 must show evidence of CA-125 
greater than or equal to two times the upper normal limit on 
two occasions at least one week apart 
OR 
2. Patients with elevated CA-125 pretreatment, which never 
normalizes must show evidence of CA-125 greater than or 
equal to two times the nadir value on two occasions at least one 
week apart 
OR 
3. Patients with CA-125 in the normal range pretreatment must 
show evidence of CA-125 greater than or equal to two times 
the upper normal limit on two occasions at least one week apart 
 
When disease progression is defined by CA-125 criteria 
alone, imaging using the same modality and encompassing 
the same field as in the initial pretreatment evaluation 
should be obtained within 2 weeks that such progression is 
documented. The patient should continue therapy, as per 
protocol, until progressive disease is documented by 
imaging. 
 
15.1.4.4 
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.

accepted as disease progression. 
 
Note: 
Patients with a global deterioration of health status requiring discontinuation of 
treatment without objective evidence of disease progression at that time should be 
reported as “symptomatic deterioration.”  Every effort should be made to document 
the objective progression even after discontinuation of treatment.

15.1.5 Duration of Response 
 
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 progressive disease is 
objectively documented.  
 
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, including the 
baseline measurements.  
 
15.1.6 Progression-Free Survival 
 
Progression-Free Survival (PFS) is defined as the duration of time from 
start of treatment to time of progression or death, whichever occurs first. 
 
15.1.7 Survival 
Survival is defined as the duration of time from start of treatment to time 
of death or the date of last contact.

APPENDIX I - GENERAL CHEMOTHERAPY GUIDELINES: 
 
 
• For 21 or 28 day cycles, a patient will be permitted to have a new cycle of chemotherapy 
delayed up to 7 days (without this being considered to be a protocol violation) for major 
life events (e.g., serious illness in a family member, major holiday, vacation which is 
unable to be re-scheduled). Documentation to justify this decision should be provided.  
• It will be acceptable for individual chemotherapy doses to be delivered within a “24-hour 
window before and after the protocol-defined date” for “Day 1” treatment of 21 or 28 day 
cycles. If the treatment due date is a Friday, and the patient cannot be treated on that 
Friday, then the window for treatment would include the Thursday (1 day earlier than 
due) through the Monday (day 3 past due).  
• For weekly regimens, it will be acceptable for individual chemotherapy doses to be 
delivered within a “24-hour window,” for example; “Day 8 chemotherapy” can be 
delivered on Day 7, Day 8, or Day 9 and “Day 15 chemotherapy” can be given on Day 
14, Day 15, or Day 16.  
• Chemotherapy doses can be “rounded” according to institutional standards without being 
considered a protocol violation (most institutions use a rule of approximately +/- 5% of 
the calculated dose).  
• Chemotherapy doses are required to be recalculated if the patient has a weight change of 
greater than or equal to 10%. Patients are permitted to have chemotherapy doses 
recalculated for < 10% weight changes.  
• Maximum body surface area used for chemotherapy dose calculations will be 2.0 m2. For 
chemotherapy dose calculations that use mg/kg, there will be no maximum kilogram 
amount used (doses will be calculated on actual weight in kg).

APPENDIX V - TRANSLATIONAL SCIENCE 
 
I. Obtaining a Bank ID for Translational Science Specimens 
Only one Bank ID (# # # # - # # - G # # #) is assigned per patient. All translational science 
specimens and accompanying paperwork must be labeled with this coded patient number. 
 
A Bank ID is automatically assigned once the Specimen Consent is completed and indicates that 
a patient has agreed to participate in the translational science component. 
 
A Bank ID can also be obtained online via the Tissue Bank Portal link on the NRG Oncology 
website. Obtain the patient’s study ID for all protocols with translational science specimen 
requirements before requesting a Bank ID from the Tissue Bank Portal. Be sure to indicate if 
the patient has a legacy GOG ID when registering. This will ensure the patient is only 
assigned one Bank ID. The GOG ID – Bank ID Lookup on the Tissue Bank Portal can be used to 
search for an existing Bank ID. 
 
Please contact User Support if you need assistance or have assigned more than one Bank ID to a 
patient (Email: support@gogstats.org; Phone: 716-845-7767). 
 
II. Requesting Translational Science Specimen Kits 
Kits are not provided for this protocol. 
 
III. Formalin-Fixed, Paraffin-Embedded Tissue Shipped to the GOG Tissue Bank 
Formalin-fixed, paraffin embedded (FFPE) tissue should be the most representative of the 
specimen type (primary, metastatic, recurrent, persistent). Primary and metastatic tumor should 
be collected prior to all treatment. Recurrent and persistent tumor should be collected prior to 
the study treatment. Recurrent or persistent tumor collected from the site of primary disease 
should be labeled recurrent primary or persistent primary, respectively. Recurrent or 
persistent tumor collected from a site other than the site of primary disease (e.g., lymph node) 
should be labeled recurrent metastatic or persistent metastatic, respectively. Only one block 
may be submitted per tissue type. 
 
Every attempt should be made to provide a FFPE block; however, if a block cannot be provided 
on a permanent basis, then 20 unstained slides (10 charged, 5µm and 10 uncharged, 10 µm) 
should be submitted. All tissue sections should be cut sequentially from the same block.  
 
Note: Stained slides to confirm patient eligibility by central pathology review are required 
for this protocol, but are NOT sent to the GOG Tissue Bank. If these slides will be cut from 
the same block that will be submitted for translational science, your pathology department should 
cut these slides prior to submitting the block for translational science. 
 
The type of specimen (block or slides) should be specified on Form TR. If submitting slides, the 
slide type, thickness, and count should also be specified.  
 
All FFPE tissue should be submitted with the corresponding pathology report.

Labeling Translational Science Specimens 
A waterproof permanent marker or printed label should be used to label each translational 
science specimen with: 
 
Bank ID (# # # # - # # - G # # #) 
protocol number (NRG - GY - # # #) 
specimen code (e.g., WB01) 
collection date (mm/dd/yyyy) 
surgical pathology accession number (tissue specimens only) 
block number (tissue specimens only) 
 
Note: If labeling slides, only label on the top, front portion of the slide. Do not place a label on 
the back of the slide or over the tissue. The label must fit on the slide and should not be wrapped 
around the slide or hang over the edge. 
 
IV. Submitting Form TR 
An electronically completed copy of Form TR must accompany each specimen shipped to the 
GOG Tissue Bank. Handwritten forms will not be accepted. 
 
Note: A copy does not need to be sent to the GOG Tissue Bank if specimens are not collected. 
  
Retain a printout of the completed form for your records. 
  
Please contact User Support if you need assistance (Email: support@gogstats.org; Phone: 716-
845-7767). 
 
V. Shipping Translational Science Specimens 
An electronically completed copy of Form TR must be included for each translational 
science specimen.  
 
A. FFPE Tissue 
FFPE tissue, an electronically completed copy of Form TR, and a copy of the corresponding 
pathology report should be shipped using your own container at your own expense to: 
 
GOG Tissue Bank / Protocol NRG-GY-001 
Nationwide Children’s Hospital 
700 Children’s Dr, WA1340 
Columbus, OH 43205 
Phone: 614-722-2865 
FAX: 614-722-2897 
Email: GOGBank@nationwidechildrens.org 
 
Do not ship FFPE tissue for Saturday delivery. 
 
VI. Distributing Translational Science Specimens 
Note: Testing of banked specimens will not occur until an amendment to this treatment protocol

(or separate correlative science protocol) is reviewed and approved in accordance with National 
Clinical Trials Network (NCTN) policies.  
 
The NRG Oncology Statistics and Data Management Center-Buffalo Office and GOG Tissue 
Bank (or alternate laboratory) will coordinate the distribution of translational science specimens 
to approved investigators. 
 
Investigators will not be given access to any personal identifiers. 
 
Investigators will be responsible for the direct supervision and oversight of the translational 
science and for keeping accurate records. 
 
Investigators will ensure the results are linked to the appropriate translational science specimen-
specific identifiers and are responsible for transferring relevant laboratory data to the NRG 
Oncology Statistics and Data Management Center-Buffalo Office. 
 
At the discretion of the Chair of the Translational Science-GYN Committee and the Director of 
the GOG Tissue Bank, investigators may be required to ship any specimens (or by-products) 
remaining after the completion of the translational science to the GOG Tissue Bank. 
 
VII. Banking Translational Science Specimens for Future Research 
Specimens will remain in the GOG Tissue Bank and made available for approved research 
projects if the patient has provided permission for the use of her specimens for future health 
research. The patient’s choices will be recorded on the signed informed consent document and 
electronically via Specimen Consent. At the time of specimen selection for project distribution, 
the most recent consent information will be used. 
 
Sites can amend a patient’s choices regarding the future use of her specimens at any time if 
the patient changes her mind. 
 
If the patient revokes permission to use her specimens, the GOG Tissue Bank will destroy or 
return any remaining specimens. The patient’s specimens will not be used for any further 
research; however, any specimens distributed for research prior to revoking consent cannot be 
returned or destroyed. In addition, the patient cannot be removed from any research that has been 
done with her specimens distributed prior to revoking consent. 
 
Note: If return of specimens is requested, shipping will be at the site’s expense.
