Study of Sorafenib + TH-302: Phase I in Advanced Renal Cell Carcinoma (RCC) and Advanced Hepatocellular Carcinoma (HCC) and Phase II in 1st Line Advanced HCC


OBJECTIVES:

Primary

- To determine the maximum-tolerated dose (MTD) and recommended Phase II dosing (RP2D)
for the combination of sorafenib tosylate and hypoxia-activated prodrug TH-302 (TH-302)
in patients with hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC; non-HCC)
advanced solid tumors. (Phase I)

- To evaluate the overall response rate (RR) determined based on modified RECIST criteria
(Lencioni and Llovet 2010) in patients with advanced HCC receiving sorafenib tosylate
with TH-302. (Phase II)

Secondary

- To characterize overall toxicity profile of sorafenib tosylate + TH-302 within patients
with HCC and RCC (non-HCC) advanced solid tumors. (Phase I)

- To characterize the responses of sorafenib tosylate + TH-302 within patients with HCC
and RCC (non-HCC) advanced solid tumors. (Phase I)

- To assess the adverse events (AEs) profile and safety profile of sorafenib tosylate in
combination with TH-302 in patients with advanced HCC. (Phase II)

- To estimate the overall response rate based on standard RECIST criteria in the study
population. (Phase II)

- To estimate the duration of response based on modified (standard) RECIST criteria in
the study population. (Phase II)

- To estimate the progression free survival (PFS) in the study population. (Phase II)

- To estimate the overall survival (OS) in the study population. (Phase II)

- To estimate the alpha-fetoprotein (AFP) response rate (defined as > 20% decrease of AFP
from baseline) in the study population. (Phase II)

OUTLINE: This is a multicenter, phase I dose-escalation study followed by a phase II study.

Patients receive sorafenib tosylate orally (PO) twice daily (BID) on days 1-28 and
hypoxia-activated prodrug TH-302 IV over 30 minutes on days 8, 15, and 22. Courses repeat
every 28 days in the absence of disease progression or unacceptable toxicity.

Some patients undergo blood sample collection periodically during study for
alpha-fetoprotein analysis.

After completion of study treatment, patients are followed up for 3 years.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Cytologically or histologically confirmed diagnosis of advanced hepatocellular
carcinoma (HCC) or renal cell carcinoma; HCC patients should not be amenable to
treatment with surgery or to orthotopic liver transplant (phase I)

- Cytologically or histologically confirmed diagnosis of hepatocellular carcinoma that
is locally advanced or metastatic and is not amenable to treatment with surgery or to
orthotopic liver transplant (phase II)

- Patients must have measurable disease

- HCC patients only:

- Advanced HCC after first-line (i.e., no prior systemic therapy) or second-line
(with prior first-line sorafenib tosylate therapy only) treatment (phase I)

- Advanced HCC after first-line treatment (i.e., no prior systemic therapy) (phase
II)

- Child Pugh class A or B7 liver disease

- Prior chemoembolization, radioembolization, radiofrequency ablation (RFA), or
other local ablative therapies are permissible if ≥ 6 weeks from procedure with
evidence of progression or new metastatic disease, if applicable

- No known central nervous system (CNS) or brain metastasis that is either symptomatic
or untreated

- Patients with neurological symptoms must undergo a computed tomography (CT)
scan/magnetic resonance imaging (MRI) of the brain to exclude brain metastasis

- Patients with CNS metastases that have been treated and are stable without
symptoms for ≥ 4 weeks after completion of treatment are eligible

- HCC patients only: cancer potentially amenable to local modalities of therapy or
surgical resection not allowed

- No fibrolamellar histology HCC, mixed hepatocholangiocarcinoma, hepatic sarcomas, and
other non-HCC primary liver tumors

PATIENT CHARACTERISTICS:

- ECOG performance status 0 or 1

- Life expectancy ≥ 3 months

- Absolute neutrophil count ≥ 1,200/mm³

- Peripheral platelet count ≥ 75,000/mm³

- Hemoglobin > 8.5 g/dL

- Total bilirubin ≤ 3.0 times upper limit of normal (ULN)

- AST and ALT ≤ 2.5 times ULN (if patient has HCC or liver metastases, then ≤ 5 times
ULN) (phase I)

- Creatinine ≤ 1.5 times ULN

- International normalized ratio (INR) ≤ 1.5 times ULN

- Negative pregnancy test done ≤ 7 days prior to registration, for women of
childbearing potential only

- Willing to return to North Central Cancer Treatment Group (NCCTG) enrolling
institution for follow-up

- Ability to receive intravenous contrast for the purpose of imaging (phase II)

- None of the following:

- Pregnant women

- Nursing women

- Men or women of childbearing potential who are unwilling to employ adequate
contraception for the duration of study participation; men and women should
continue to use adequate birth control after the last administration of
sorafenib tosylate and hypoxia-activated prodrug TH-302 (TH-302) under the
guidance of their treating physician

- No co-morbid systemic illnesses or other severe concurrent disease which, in the
judgment of the investigator, would make the patient inappropriate for entry into
this study or interfere significantly with the proper assessment of safety and
toxicity of the prescribed regimens

- No other active malignancy ≤ 3 years prior to registration; EXCEPTIONS: non-melanotic
skin cancer or carcinoma-in-situ of the cervix; NOTE: if there is a history or prior
malignancy, they must not be receiving other specific treatment (other than hormonal
therapy) for their cancer

- No inadequately controlled hypertension (systolic blood pressure of > 150 mm Hg or
diastolic pressure > 100 mm Hg on anti-hypertensive medications)

- No New York Heart Association (NYHA) classification III or IV congestive heart
failure

- No known or suspected allergy or hypersensitivity to any component of TH-302,
sorafenib tosylate, or any of the sorafenib tosylate excipients

- No condition that severely impairs patient's ability to swallow whole pills

- No QTc interval > 500 msec on baseline electrocardiogram (EKG)

- No documented history of prolonged QTc interval ≤ 6 months prior to registration

- No traumatic injury in the past 14 days

PRIOR CONCURRENT THERAPY:

- See Disease Characteristics

- Not receiving any other investigational agent

- No major surgical procedures prior to registration or anticipation of need for
elective or planned major surgical procedure during the course of the study
