About
The objectives of this study is to estimate the biological activity of combination chemotherapy and radiation versus radiation alone in patients with Hepato Cellular Carcinoma (HCC).
The study hypothesizes is that combination chemotherapy and radiation is superior to radiation alone in inducing a biological response. The study hypothesizes that combination chemotherapy and radiation is superior to radiation alone in inducing a biological response. A biological response, or change in the tumor microenvironment (TME), is defined by reduced infiltration of intra-tumoral regulatory T cells (Tregs), a decrease in tumour-associated macrophages (TAMs) of the M2 phenotype, and an increase in immune cells such as effector CD8+ T-cells. An increased rate of biological response is therefore expected in participants receiving the combination of Durvalumab, Tremelimumab, and stereotactic body radiation therapy (SBRT), compared to those receiving SBRT alone. Additionally, biological response is hypothesized to correlate with pathological response.
The study has been conducted within a WOO window of opportunity randomized clinical trial in order to obtain data in the quickest and safest manner. Patients undergoing surgery are very healthy by definition and will be able to tolerate treatment without any major complications, leading to adequate tissue samples before and after treatment.

Volunteers
Inclusion criteria
Tumour less than 12 cm in maximum size on CT or MRI.
Planned surgical resection of HCC with a life expectancy of at least 12 weeks
Age >18 years at time of study entry.

Body weight >30 kg at time of study enrollment
Adequate normal organ and marrow function as defined below:
Haemoglobin ≥9.0 g/dL
Absolute neutrophil count (ANC ≥1.0 × 109 /L)
Platelet count ≥75 × 109/L
Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN).
AST (SGOT)/ALT (SGPT) ≤2.5 x institutional upper limit of normal
Measured creatinine clearance (CL) >40 mL/min or Calculated creatinine clearance CL>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance:
Males:
Creatinine CL (mL/min) = Weight (kg) x (140 - Age)72 x serum creatinine (mg/dL)
Females:
Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL)
Patient is capable and willing to provide signed informed consent.
Exclusion criteria
Participation in another clinical study with an investigational product during the last 4 weeks or concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.
Previous radiation therapy or surgery within 4 weeks of the randomization.
Previous allogenic organ transplantation
Previous anti-PD-1, anti-PD-L1 or anti-CTLA-4 therapy
Previous receipt of durvalumab and / or tremelimumab or allergy to it
Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy except for alopecia, vitiligo, and the laboratory values defined in the inclusion criteria
Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab or tremelimumab may be included only after consultation with the Study Physician.
Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.]). The following are exceptions to this criterion:
Patients with vitiligo or alopecia
Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement
Any chronic skin condition that does not require systemic therapy
Patients without active disease in the last 5 years may be included but only after consultation with the study physician
Patients with celiac disease controlled by diet alone
History of active primary immunodeficiency
Conditions that would preclude administration of durvalumab and / or tremelimumab
Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent
Known active hepatitis infection, positive hepatitis C virus (HCV) antibody, hepatitis B virus (HBV) surface antigen (HBsAg) or HBV core antibody (anti-HBc), at screening. Patients with a past or resolved HBV infection (defined as the presence of antiHBc and absence of HBsAg) are eligible. Patients positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
b.1. Patients co-infected with HBV and HCV or co-infected with HBV and HDV, namely: HBV positive (presence of HBsAg and/or anti HBcAb with detectable HBV DNA); and
b.2. HCV positive (presence of anti-HCV antibodies); or
b.3. HDV positive (presence of anti-HDV antibodies)
b.4. Patients with HBV infection, characterized by positive HBsAg and/or anti-HBcAb with undetectable HBV DNA (< 10 IU/ml or under the limit of detection per local lab standard) do not require antiviral therapy prior to enrollment. These patients will be tested once for HBV DNA levels; if HBV DNA is detected (≥ 10 IU/ml or above the limit of detection per local lab standard), antiviral therapy must be initiated, continued for the study duration and for 6 months after the last dose of IP.
Known to have tested positive for human immunodeficiency virus (HIV) (positive HIV 1/2 antibodies) which is not well controlled or active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice).
c.1. All of the following criteria are required to define an HIV infection that is well controlled: undetectable viral RNA load for 3 months, CD4+ count of >200 no history of AIDS-defining opportunistic infection within the past 12 months, and stable for at least 3 months on the same anti-HIV medications.
History of another primary malignancy, except for
Malignancy treated with curative intent and with no known active disease ≥2 years before randomization and of low potential risk for recurrence
Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
Adequately treated carcinoma in situ without evidence of disease
Current or prior use of immunosuppressive medication within 14 days before enrollment. The following are exceptions to this criterion:
Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)
Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent
Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
Receipt of live attenuated vaccine within 30 days prior to enrollment. Note: Patients, if enrolled, should not receive live vaccine whilst receiving IP and up to 90 days after the last dose of IP.
Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential who are not willing to employ effective birth control from screening to 180 days after the last dose of durvalumab and tremelimumab combination therapy.
