Summary:
Hepatocellular carcinoma (HCC) is the 7th most common cancer worldwide but is the 4th
deadliest, because diagnosis tend to be late and current systemic therapies are poorly
efficacious. Within the same tumour, different parts of the HCC can belong to separate
molecular sub-groups. In addition, there is currently no validated predictive biomarkers
to help clinicians select the best therapy for an individual patient. This challenge
poses an urgent, unmet clinical need.
To address this, the multi-disciplinary research program Precision Medicine in Liver
Cancer across an Asia-Pacific Network (PLANet 1.0) was conceptualized and successfully
conducted from 2016-22. The program uncovered novel insights into the highly
heterogeneous molecular landscape of HCC and novel mechanisms, including how HCC reverts
to fetal forms to escape the body's immunological defence.
These investigations will be continued in PLANet 2.0 and in this new phase, the research
team will investigate patients receiving best-in-class therapeutics in 2
investigator-initiated clinical studies (AHCC12 and AHCC13), including Atezolizumab plus
Bevacizumab (Atezo+Bev) and Yttrium-90, which allows the research team to collect
longitudinal, before and after treatment biosamples and clinical data. These clinical
studies will serve as proof-of-concept to the study team's translational findings and
allow it to uncover predictive biomarkers which will help clinicians to institute more
efficacious and personalized treatment in the future. The research team comprises of
experts in different complementary fields (epigenomics, genomics, immunomics,
metabolomics, proteomics, clinical science and data science) and across different
institutions. This allows the team to adopt an integrative approach in understanding the
landscape of the HCC tumour micro-environment and biomarkers co-localisation, and their
role in tumour evolution and therapeutic response. By adopting a wide spectrum of
converging investigations, PLANet 2.0 will identify and validate biomarkers that
correlate with clinical outcomes (response, resistance and recurrence).
Detailed description:
This is a clinical translational study on a prospective, interventional clinical cohort
(defined as the AHCC12 study). Patient will receive adjuvant Atezolizumab plus
Bevacizumab every 3-weekly for a year following surgery. Serially collected biosamples
will be deeply-phenotyped and correlated with treatment outcomes (recurrence vs
non-recurrence).
Criteria for eligibility:
Criteria:
Inclusion Criteria:
1. Patient is willing, able and mentally competent to provide written informed consent
prior to any testing undertaken for this study protocol, including screening tests
and evaluations that are not considered to be part of the patient's routine care.
2. Male and female patients, age 21 to 90 at the time of signature of the informed
consent form.
3. Patient is able to comply with scheduled visits, assessments and other study
procedures.
4. Patient diagnosed with HCC or its histological variants who has undergone a
resection within 4-12 weeks prior to Day 1 of Cycle 1.
- Multimodality treatment is not permitted, for example resection and ablation
- Combination treatment is not permitted.
5. Patient has clinically AND histologically proven HCC after liver resection as
described below:
- Patients must have documented histological HCC confirmation of negative
surgical margins (R0) which is documented in a pathology report (patients with
microscopically positive [R1] or grossly positive [R2] resection margins or
unknown margins will be excluded from the study).
- Patients must have disease-free status documented within 4 weeks prior to Day 1
of Cycle 1 by a complete physical examination and radiographic images, with no
subsequent evidence of residual or recurrent disease prior to Day 1 of Cycle 1.
A complete set of baseline (post-resection) radiographic images and
accompanying report must be available prior to Day 1 of Cycle 1.
6. Patient has an absence of major macrovascular (gross vascular) invasion of the
portal vein (Vp3 or Vp4) or major macrovascular invasion in the inferior vena cava
(Vv3).
7. Patient has an absence of extrahepatic spread as confirmed by CT or MRI scan of the
chest, abdomen, pelvis, and head prior to and following resection . If head scan was
not performed prior to resection, this must be performed after resection.
8. Patient has a full recovery from surgical resection within 4 weeks prior to Day 1 of
Cycle 1.
9. Patient is at high risk for HCC recurrence after resection as defined in Table 1:
- Up to three tumours, with largest tumour > 5 cm regardless of vascular invasion
(microvascular invasion or macrovascular invasion of the portal vein - Vp1/Vp2
or hepatic vein - Vv1/Vv2), or poor tumour differentiation (Grade 3 or 4)
- Up to three tumours, with largest tumour ≤ 5cm with vascular invasion
(microvascular invasion or macrovascular invasion of the portal vein - Vp1/Vp2
or hepatic vein - Vv1/Vv2) and/or poor tumour differentiation (Grade 3 or 4)
- Four or more tumours, with largest tumour ≤ 5 cm regardless of microvascular
invasion (microvascular invasion or macrovascular invasion of the portal vein -
Vp1/Vp2 or hepatic vein - Vv1/Vv2) or poor tumour differentiation (Grade 3 or
4)
- In the event that the pathology and the pre- resection radiology report are
discordant with regards to tumour size and number, the modality demonstrating
the largest tumour size and number should be used to determine high risk
features. Pathological findings should be used to assess for microvascular
invasion and/or poor tumour differentiation. If macrovascular invasion of Vp1
or Vp2 or Vv1 or Vv2 is detected on either the pre-operative CT/MRI scan or the
pathology report, this should be a high risk feature
10. Patient has baseline tumour tissue samples that meet the following criteria:
- Good DNA/RNA quality (Refer to Biosamples Collection Protocol)
- High tumour viability (Refer to Biosamples Collection Protocol)
11. Patient is known to be negative for the Human Immunodeficiency Virus (HIV).

continued on antiviral treatment to obtain HBV DNA < 500 IU/mL before Day 1 of
Cycle 1. Antiviral treatment shall continue throughout the entire Atezo+Bev
treatment phase.

liver resection, systemic therapy (including investigational agents) and
locoregional therapy (e.g. RFA, TACE, SIRT), radiotherapy, immunotherapy,
chemotherapy or neo-adjuvant chemotherapy other than the planned surgery. However,
patient who has received previous HCC resection more than 5 years ago is deemed to
have a de-novo liver tumour and therefore can be included.
- Prior use of herbal therapies or traditional Chinese medicines with anti-cancer
activity included in the label is allowed, but such therapies must be
discontinued at least 7 days prior to Day 1 of Cycle 1 and are prohibited
during the study.
- Portal vein embolization used to increase the functional liver remnant prior to

25. Patient has received prior treatment with systemic immunosuppressive medication
(including, but not limited to, corticosteroids, cyclophosphamide, azathioprine,
methotrexate, thalidomide, and anti-tumour necrosis factor-α [TNF-α] agents) within
2 weeks prior to Day 1 of Cycle 1, or anticipation of need for systemic
immunosuppressive medication during study treatment, with the following exceptions:

days prior to Day 1 of Cycle 1.

mg/day) is allowed. However, the use of direct oral anticoagulant therapies
such as dabigatran (Pradaxa®) and rivaroxaban (Xarelto®) is not recommended due
to bleeding risk. Benefits and risks should be assessed and caution exercised
for use of direct oral anticoagulants. The investigator should consider
switching to other approved anticoagulants due to the risk of upper GI bleeding
in patients with HCC.
