Safety and Efficacy Evaluation of Tremelimumab Plus Durvalumab(MEDI4736) in Combination with Concurrent Transarterial Chemoembolization in Unresectable Hepatocellular carcinoma
Full description
The purpose of this clinical trial is to evaluate the safety and efficacy of tremelimumab + durvalumab administered concurrently with transarterial chemoembolization (TACE) in patients diagnosed with hepatocellular carcinoma (HCC) who are not eligible for curative liver resection.
Primary Objective:
The primary objective of this clinical trial is to evaluate progression-free survival (PFS) from the time of registration using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
Secondary Objectives:
Overall Survival (OS):
To assess the overall survival from the first dose of the study drug until the data cutoff point, as determined by the investigator.
Objective Response Rate (ORR):
To assess the objective response rate of target and non-target lesions using mRECIST and RECIST 1.1. Evaluations will occur every 8 weeks after 12 weeks and for the first 48 weeks from the time of registration, and then every 12 weeks thereafter.
Time to Progression (TTP):
To measure the time from registration to disease progression using mRECIST and RECIST 1.1.
Safety Evaluation:
To evaluate the safety of tremelimumab and durvalumab, including adverse events, vital signs (blood pressure and pulse rate), and laboratory safety assessments (clinical chemistry, hematology, etc.), by assessing changes from baseline.

Barcelona clinic liver cancer (BCLC) staging intermediate (B) stage or BCLC advanced stage (C) HCC with or without minimal extrahepatic disease (single-organ metastasis, ≤5 metastatic lesions).
Must have at least 1 untreated measurable disease (untreated target lesion i.e. a viable lesion that has never been treated with locoregional treatment [transarterial chemoembolization {TACE}, TARE, percutaneous ethanol injection therapy, or radiofrequency ablation]).
Child-Pugh score 5 or 6 points (Child-Pugh class A). 7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 8. Life expectancy of ≥ 12 weeks. 9. Body weight >30 kg. 10. Adequate normal organ and marrow function as defined below:
Males:
Creatinine CL (mL/min) Females:
Creatinine CL (mL/min)
Male patients must be surgically sterile or, if sexually active and having a pre-menopausal female partner then, must be using an acceptable form of contraception.
Adequate contraception allowed in this trial is as follows:
Hormonal contraceptives such as combined oral contraceptive pill
Intrauterine devices or the implantation of intrauterine system (IUS)
Blockage methods (spermicides and condoms/spermicides and vaginal diaphragm for contraception, vaginal sponges or cervical cap) • Blockage methods (spermicides and condoms/spermicides and vaginal diaphragm for contraception, vaginal sponges or cervical cap)
Sterilization surgery such as tubal ligation in females and vasectomy in males. 12. Evidence of postmenopausal status or negative urinary or serum pregnancy test for female premenopausal patients. Women will be considered postmenopausal if they have been amenorrhoeic for 12 months without an alternative medical cause. The following age-specific requirements apply:
Women <50 years of age would be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the postmenopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
Women ≥50 years of age would be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
Exclusion criteria
Eligible for potentially curative treatment (surgical resection, radiofrequency ablation or immediate liver transplantation).
Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti- Cytotoxic T-lymphocyte- associated antigen-4 (anti-CTLA-4) antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune pathways, including prior randomization or treatment in a previous durvalumab and/or tremelimumab clinical study regardless of treatment arm assignment.
History of organ transplantation or hematopoietic stem cell transplantation.
Any other concurrent malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, papillary thyroid cancer, early gastric cancer, or other cancer for which the patient has been disease-free for at least five years.
A history of a severe contrast allergy (i.e. anaphylaxis) not controlled with premedication.
Any condition that, in the opinion of the Investigator, would interfere with evaluation of the investigational product (IP) or interpretation of patient safety or study results.
Participation in another clinical study with an IP during the last 8 weeks or 5 half-lives of the study drug, whichever is longer, prior to screening.
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.
Receipt of the last dose of anticancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies) ≤1 cycle length or 14 days, whichever is longer, prior to the first dose of study drug. If sufficient wash-out time has not occurred due to the schedule or PK properties of an agent, a longer wash-out period will be required, as determined by the Investigator.
Any unresolved toxicity NCI-CTCAE Grade ≥2 from previous anticancer therapy with the exception of 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 and/or tremelimumab may be included at the discretion of the Investigator.
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.
Prior hepatic radiation therapy including Total Body Irradiation (TBI) for HCC or other malignancy.
Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable.
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.]).

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 adverse events (AEs) or compromise the ability of the patient to give written informed consent.
History of leptomeningeal carcinomatosis. 17. History of active primary immunodeficiency, including known positive tests for human immunodeficiency virus (HIV 1/2 antibodies).
Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice), other than chronic infection of HBV or HCV. Participants with chronic HBV infection (positive hepatitis B surface antigen [HBsAg] and/or detectable HBV DNA) are eligible if they are receiving nucleos(t)ide analog treatment, as determined by the physician's judgment and in accordance with local practice guidelines. Those with a past or resolved HBV infection (defined as the presence of anti-hepatitis B core antibody and absence of HBsAg) are also eligible. For chronic HCV infection, participants positive for HCV antibody are eligible only if polymerase chain reaction for HCV RNA is negative.
