About

The purpose of this study is to evaluate the effect of liver-localised radioembolization and nivolumab on liver cancer.

Full description

The hypothesis is that liver-localized radioembolization will stimulate tumour and/or HBV specific T cell responses that are associated with favourable patient outcomes and that can be boosted using nivolumab anti-PD1 checkpoint blockade immunotherapy.

Primary objective

To evaluate the response rates of Y90 radioembolization in combination with nivolumab in HCC

Secondary objectives

To evaluate time to response, response duration, time to treatment progression and sites of progression when RE is combined with nivolumab
To assess progression free survival and overall survival when RE is combined with nivolumab
To assess the quality of life using the FACT-HEP score and EORTC QLQ-C30
To assess the safety and tolerability of the combination of RE and nivolumab

Exploratory objectives

To evaluate the relationship between tumor biopsy PD-L1 expression and response to treatment with Y90 radioembolization in combination with nivolumab
To assess relationship between blood lymphocyte (e.g., T cell) activation and phenotypic profiles with response to treatment with Y90 radioembolization in combination with nivolumab, using mass cytometry and fluorescence flow cytometry.
To assess relationship between HCC tumour mutational burden and response to treatment with Y90 radioembolization in combination with nivolumab using whole-exome sequencing of tumour biopsy samples
Where possible, to evaluate antigen-specific T cell responses to known HBV, HCC tumour (including candidate mutation-derived tumour neo-antigens) and other unrelated antigens (e.g. CMV, EBV, Influenza) in the blood and to assess kinetic changes in these responses associated with response to treatment with Y90 radioembolization in combination with nivolumab using mass cytometry and fluorescence flow cytometry.

Administration of study drug The first dose of nivolumab will be administered 21 days (+/- 3 days) after completion of RE. [The dose of Yttrium-90 will be determined as per institution norm by the Nuclear Medicine physician, based on factors such as the subject's Body Surface Area (BSA), the size of the tumour within the liver, and any dose modifications required for percent lung shunting between 10 - 20% on the Tc-99MMA scan].

The dose given will be intravenous 240mg absolute over 30 minutes. Subsequent doses of nivolumab will be administered in the outpatient setting at NCCS. After the first dose, intravenous nivolumab 240mg will be given every 2 weeks.

A US or CT guided liver biopsy will be conducted by an interventional radiologist on C1D8 Subjects will be assessed for the following at EVERY visit: physical examination, ECOG status, vital signs, Child-Pugh score and ALBI score CT or MRI scans to assess response to treatment will be done before cycle 4, 8, 12 and then after every 12 weeks thereafter (±7 days).

FACT-HEP and EORTC QLQ C30 version 3.0 questionnaire at cycle 4 and 8.

Follow-Up Visit will be done 2-3 months after last dose. Survival updates will be obtained by phone every 3-4 months after the follow-up visit and any new anti-cancer treatment given to the subject will be recorded.

Inclusion criteria

Patients with hepatocellular carcinoma (HCC) that is not suitable for resection or liver transplant, who are planned for Y90 radioembolization as per institutional practice.
Patients must have measurable disease with target lesion in liver, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >20 mm with conventional techniques or as >10 mm with spiral CT scan.
Diagnosis of HCC confirmed by histology/cytology or clinically by AASLD criteria in cirrhotic subjects. Patients without cirrhosis require histological confirmation of diagnosis
No prior Y90 radioembolization therapy. Prior local therapies, such as surgery, hepatic artery embolization/chemoembolization, radiofrequency ablation, percutaneous ethanol injection or cryoabalastion is allowed, if the index lesion(s) remains outside of the treatment field or has progressed since prior treatment. Local therapy must have been completed at least 4 weeks prior to the baseline scan
Age ≥ 21 years.
ECOG performance status ≤ 2
Life expectancy of greater than 3 months
Only patients with Child-Pugh score for liver cirrhosis of A (sum of scores for five parameters: 5-6) will be allowed into this trial
Subjects with HBV infection must be on antiviral therapy per regional standard of care guidelines prior to initiation of study therapy. Both HBeAg positive and negative subjects will be included.
Patients must have lesions in the liver that are amenable to CT-guided liver biopsy
Patients must have normal organ and marrow function as defined below:
- Haemoglobin ≥ 8.5g/dL
- Absolute Neutrophil Count ≥ 1.5 x 10^9/L
- Platelets ≥ 50 x 10^9/L
- Total Bilirubin < 3 mg/dL
- AST(SGOT)/ALT (SGPT) ≤ 3 x ULN
- Creatinine ≤ 1.5 x ULN or measured/calculated Creatinine Clearance (CrCl) ≥ 60 ml/min
Ability to understand and the willingness to sign a written informed consent document.
Any surgery must be more than 28 days before start of study drug and any surgical wounds must be completely healed
Female subjects of childbearing potential must have a negative serum or urine pregnancy test within 3 days prior to receiving the first dose of study medication, and must agree to adequate contraception use from time of signing the informed consent through to 120 days after the last dose of the study drug. Male subjects must agree to adequate contraception use from time of signing the informed consent through 120 days after the last dose of the study drug.

Exclusion criteria

Patients are excluded if they are receiving any other investigational agents or using an investigational device within 4 weeks of first dose of treatment. Patients are excluded if they are receiving other systemic therapy within 2 weeks of first dose of treatment.
Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
Prior use of anti-PD1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody, or any drug specifically targeted T-cell costimulatory checkpoint pathways
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, uncontrolled hypertension or psychiatric illness/social situations that would limit compliance with study requirements.
Subjects with any active autoimmune disease or history of known or suspected autoimmune disease requiring systemic therapy within the past 2 years, except for subjects with vitiligo, resolved childhood asthma/atopy or euthyroid patients with a history of Grave's disease (subjects with suspected autoimmune thyroid disorders must be negative for thyroglobulin and thyroid peroxidase antibodies and thyroid stimulating immunoglobulin prior to randomization). Replacement therapy (e.g. with thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency etc) is not considered a form of systemic treatment
Pregnant women or breastfeeding mothers are excluded from this study because of the potential risks to the foetus or baby. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

Subjects with concomitant second malignancies (except adequately treated non-melanomatous skin cancers, in situ cervical cancers, localized prostate cancer or in situ breast cancer) are excluded unless a complete remission was achieved at least 3 years prior to study entry and no additional therapy is required or anticipated to be required
Prior radiation therapy to the liver or upper abdomen
Inability to undergo Y-90 radioembolisation due to inability to cathterise the hepatic artery, portal vein thrombosis/occlusion limiting the ability to perform selective infusion, Tc-99M MAA scan showing unfavourable shunt fraction between the liver and pulmonary parenchyma, any other contraindications to RE as determined by the interventional radiologist (e.g. other anatomic variants precluding safe administration of Y90, severe peripheral vascular disease, uncorrectable coagulopathy etc)
