Brief Summary:
This is a Phase II study in patients with advanced liver cancer (hepatocellular carcinoma) as a result of hepatitis B and/or C infection. Participants will be dosed with either MTL-CEBPA (an experimental treatment) and sorafenib or sorafenib alone. The MTL-CEBPA is administered once every 3 weeks via intravenous infusion. Sorafenib is taken orally from Day 8 for the combination group or Day 1 for the sorafenib alone group at a dose of 400 mg twice a day. Participants will receive 3 week cycles of treatment until disease progression, unacceptable toxicity, withdrawal of consent or death occurs. The combination of MTL-CEBA and sorafenib combination of treatment was tested in a previous Phase I study (OUTREACH) which showed anti-tumour activity along with a good safety and toxicity profile.

Hepatocellular Carcinoma Hepatitis B Hepatitis C Drug: MTL-CEBPA Drug: Sorafenib Phase 2

Detailed Description:
After a participant has signed the consent form to confirm they wish to participate in the study a number of assessments (screening) will be completed to determine whether they are suitable to be enrolled in the study. Prior to the the first dose of experimental drug (MTL-CEBPA) a 2:1 randomisation programme will allocate to which arm the person will be allocated. For participants allocated to the combination treatment arm, MTL-CEBPA will be given via infusion on the first day (Cycle 1 Day 1) of the study. It will subsequently be administered every 21 days. Sorafenib tablets (a drug which is already used to treat liver cancer) will be started on the eighth day of the study and taken daily whilst the participant is in the study. If the participant is tolerating the combination of drugs and there is no evidence that the cancer is advancing they will continue to receive cycles (21 days in length) of treatment. For participants allocated to the single treatment arm, sorafenib tablets will be started on Day 1. All participants will have contrast-enhanced CT scans of the chest, abdomen and pelvis at the beginning of the study and then every 8 weeks whilst in the study. Assessments will be completed throughout the study to ensure the combination of drugs is safe. These will include recording any adverse events (untoward medical occurrences), vital signs (such as blood pressure, pulse, body temperature, and breathing rates), ECG, and completing blood tests. Blood samples, analysed in both local (hospital/clinic site) and central laboratories (ie, facilities independent of hospital/clinic labs) will be taken throughout the study. The maximum amount of blood taken in any 28-day treatment cycle is approximately 182 mL. A patient questionnaire will be used to assess changes in health-related quality of life for participants. The questionnaire will be used for all participants in the study and will be completed every 3 weeks. All participants will be offered an optional liver tumour biopsy prior to being administered study treatment and again if clinically feasible during treatment.

Participants who are HCV Ab positive but HCV RNA negative due to prior treatment or natural resolution will be eligible. Participants with past or controlled ongoing hepatitis B will be eligible as long as their HBV viral load is less than 500 IU/mL prior to first dose of study drug.

Note: a woman is considered of child-bearing potential following menarche and until becomingpost-menopausal unless permanently sterile. Permanent methods of sterilisation include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. A post-menopausal state is defined as no menses for 12 months without an alternative medical cause. additional information / requirements in Section 5.1.) 25.Female participants of childbearing potential must use highly effective* contraceptive measures adequate to prevent a new pregnancy for the duration of the study treatment with MTL-CEBPA and sorafenib and, in addition, for at least six months after the last dose of MTL-CEBPA and six months beyond the last dose of sorafenib, as recommended in sorafenib's U.S. Package Insert (USPI). For women with reproductive potential who use a hormonal method of contraception, concurrent use of a second (barrier) method is recommended. * Highly effective methods of birth control are defined as those that result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly (e.g. implants, injectables, oral contraceptives, some intrauterine devices, bilateral tubal occlusion, true sexual abstinence in line with the preferred and usual lifestyle of the participant, or vasectomised partner). (See additional information / requirements HMA_CTFG_Contraception.pdf) 26.Male participants with partners of child-bearing potential must use highly effective contraception and are required to use barrier contraception plus an additional contraceptive method that together result in a failure rate of <1% per year during the treatment period and for at least three months after the last dose of MTL-CEBPA. Male participants will also be advised to abstain from sexual intercourse with pregnant or lactating women, or to use condoms. Male participants with partners of child-bearing potential must use highly effective contraception during treatment with sorafenib and for 3 months beyond the last dose of sorafenib, as recommended in sorafenib's USPI.

27.Abstinence is only acceptable if it is line with the preferred and usual lifestyle of the participant.
