Enhancing chemosensitivity is one of the largest unmet medical needs in cancer therapy. Cyclic GMP-AMP synthase (cGAS) connects genome instability caused by platinum-based chemotherapeutics to type I interferon (IFN) response. Here, by using a high-throughput small-molecule microarray-based screening of cGAS interacting compounds, we identify brivanib, known as a dual inhibitor of vascular endothelial growth factor receptor and fibroblast growth factor receptor, as a cGAS modulator. Brivanib markedly enhances cGAS-mediated type I IFN response in tumor cells treated with platinum. Mechanistically, brivanib directly targets cGAS and enhances its DNA binding affinity. Importantly, brivanib synergizes with cisplatin in tumor control by boosting CD8 T cell response in a tumor-intrinsic cGAS-dependent manner, which is further validated by a patient-derived tumor-like cell clusters model. Taken together, our findings identify cGAS as an unprecedented target of brivanib and provide a rationale for the combination of brivanib with platinum-based chemotherapeutics in cancer treatment.

Randomized Controlled Trial
BACKGROUND
Brivanib is a selective inhibitor of vascular endothelial growth factor and fibroblast growth factor (FGF) signalling. We performed a phase II randomised discontinuation trial of brivanib in 7 tumour types (soft-tissue sarcomas [STS], ovarian cancer, breast cancer, pancreatic cancer, non-small-cell lung cancer [NSCLC], gastric/esophageal cancer and transitional cell carcinoma [TCC]).
PATIENTS AND METHODS
During a 12-week open-label lead-in period, patients received brivanib 800 mg daily and were evaluated for FGF2 status by immunohistochemistry. Patients with stable disease at week 12 were randomised to brivanib or placebo. A study steering committee evaluated week 12 response to determine if enrolment in a tumour type would continue. The primary objective was progression-free survival (PFS) for brivanib versus placebo in patients with FGF2-positive tumours.
RESULTS
A total of 595 patients were treated, and stable disease was observed at the week 12 randomisation point in all tumour types. Closure decisions were made for breast cancer, pancreatic cancer, NSCLC, gastric cancer and TCC. Criteria for expansion were met for STS and ovarian cancer. In 53 randomised patients with STS and FGF2-positive tumours, the median PFS was 2.8 months for brivanib and 1.4 months for placebo (hazard ratio [HR]: 0.58, p = 0.08). For all randomised patients with sarcomas, the median PFS was 2.8 months (95% confidence interval [CI]: 1.4-4.0) for those treated with brivanib compared with 1.4 months (95% CI: 1.3-1.6) for placebo (HR = 0.64, 95% CI: 0.38-1.07; p = 0.09). In the 36 randomised patients with ovarian cancer and FGF2-positive tumours, the median PFS was 4.0 (95% CI: 2.6-4.2) months for brivanib and 2.0 months (95% CI: 1.2-2.7) for placebo (HR: 0.56, 95% CI: 0.26-1.22). For all randomised patients with ovarian cancer, the median PFS in those randomised to brivanib was 4.0 months (95% CI: 2.6-4.2) and was 2.0 months (95% CI: 1.2-2.7) in those randomised to placebo (HR = 0.54, 95% CI: 0.25-1.17; p = 0.11).
CONCLUSION
Brivanib demonstrated activity in STS and ovarian cancer with an acceptable safety profile. FGF2 expression, as defined in the protocol, is not a predictive biomarker of the efficacy of brivanib.

BACKGROUND
Oral multikinase inhibitors and immune checkpoint inhibitors (ICIs) are effective for treating advanced hepatocellular carcinoma (aHCC) but may increase cost. This study compared the cost-effectiveness of oral multikinase inhibitors and ICIs in the first-line treatment of patients with aHCC.
METHODS
A three-state Markov model was established to study the cost-effectiveness of drug treatment from the perspective of Chinese payers. The key outcomes in this study were total cost, quality-adjusted life years (QALYs), and the incremental cost-effectiveness ratio (ICER).
RESULTS
The total costs and QALYs of sorafenib, sunitinib, donafenib, lenvatinib, sorafenib plus erlotinib, linifanib, brivanib, sintilimab plus IBI305, and atezolizumab plus bevacizumab were $9070 and 0.25, $9362 and 0.78, $33,814 and 0.45, $49,120 and 0.83, $63,064 and 0.81, $74,814 and 0.82, $81,995 and 0.82, $74083 and 0.85, and $104,188 and 0.84, respectively. The drug regimen with the lowest ICER was sunitinib ($551 per QALY), followed by lenvatinib ($68,869 per QALY). For oral multikinase inhibitors, the ICER of lenvatinib, sorafenib plus erlotinib, linifanib and brivanib compared with sunitinib was $779576, $1534,347, $1768,971, and $1963,064, respectively. For ICIs, sintilimab plus IBI305 is more cost effective than atezolizumab plus bevacizumab. The model was most sensitive to the price of sorafenib, the utility of PD, and the price of second-line drugs.
CONCLUSION
For oral multikinase inhibitors, the order of possible treatment options is sunitinib > lenvatinib > sorafenib plus erlotinib > linifanib > brivanib > donafenib. For ICIs, the order of possible treatment options is sintilimab plus IBI305 > atezolizumab plus bevacizumab.

Review
BACKGROUND
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. The outcome of HCC therapy depends on the stage of HCC. Early-stage HCC patients can be cured with radical treatment approaches, whereas no standard treatment regimens can be recommended for patients with advanced disease.
SUMMARY
In-depth basic research into the molecular mechanisms of HCC has contributed to the development of novel therapeutic agents. This article reviews several key classes of novel therapeutic agents that are under development, including molecular-targeted therapies, cancer stem cell (CSC)-based therapy and differentiation therapy.
KEY MESSAGE
A greater understanding of the molecular pathogenesis of HCC has contributed to the development of novel therapeutic agents. This article reviews several key classes of novel therapeutic agents that are under development, including molecular-targeted therapies, CSC-based therapy and differentiation therapy.
PRACTICAL IMPLICATIONS
Molecular-targeted therapies based on signaling pathways involved in hepatocarcinogenesis and progression are being evaluated in several clinical trials. There are three main categories of targeted agents: tyrosine kinase inhibitors (TKIs), monoclonal antibodies and enzyme inhibitors. The best-established agent is sorafenib, a non-specific TKI that is accepted as first-line therapy for specific patients. Other similar agents under investigation include erlotinib, linifanib and brivanib. CSC-based therapies are still in the earlier stages of development and include a neutralizing anti-CD44 antibody, small interfering RNA to suppress epithelial cell adhesion molecular levels, a neutralizing anti-CD13 antibody and a CD13 inhibitor. An important point is that CSC-targeted therapy should be combined with conventional therapies to achieve complete tumor regression. Differentiation therapy is defined as a strategy that induces malignant reversion of tumor cells. Hepatocyte nuclear factor 4α or 1α, important transcriptional factors for hepatocyte differentiation and phenotype maintenance, have shown significant antitumor effects by inducing differentiation of both non-CSCs and CSCs in HCC towards a hepatocyte-like phenotype.

Review
Hepatocellular carcinoma (HCC) is a common cancer with high incidence and mortality worldwide. The main treatments for HCC include radical hepatectomy, liver transplant, locoregional therapies, and systemic therapies. Systemic treatments include targeted agent treatment, chemotherapies, antiviral therapies, and nutritional treatments. According to the results of SHARP and ORIENTAL study, sorafenib became the standard first-line therapy since 2008 because of nearly three months of survival improvement in patients with advanced HCC. Subsequent studies on targeted agents found that neither sunitinib nor brivanib were superior to sorafenib as first-line therapy. After progression or intolerance of sorafenib, brivanib did not improve the overall survival (OS) compared with placebo as second-line therapy. Randomized controlled EACH study and retrospective AGEO study for systemic chemotherapy showed that oxaliplatin-based or gemcitabine-based regimen was effective for advanced HCC patients. Randomized controlled trial for adjuvant chemotherapy in China showed that capecitabine could reduce the risk of recurrence and improve postoperative survival of HCC. Comparing sorafenib with other treatments, several retrospective studies found that other treatments were not inferior to sorafenib in terms of OS. In the systemic treatment of HCC, antiviral treatment can decrease the recurrence of HBV-related HCC postoperation and prolong the survival of patients. Based on the etiology, symptoms, complications, and treatment-related side effects, nutritional treatment is also very important for HCC patients. Systemic chemotherapy, newer targeted agents, and immune therapy are the new directions in future research.

Review
BACKGROUND AND AIMS
Assessing treatment responses in hepatocellular carcinoma (HCC) is challenging, and alternative radiologic methods of measuring treatment response are required. Modified Response Evaluation Criteria in Solid Tumors (mRECIST) for HCC and alpha-fetoprotein (AFP) levels were assessed in a post hoc analysis of a phase II study of brivanib, a selective dual inhibitor of fibroblast growth factor and vascular endothelial growth factor signaling.
METHODS
HCC patients were treated with first-line (cohort A; n = 55) or second-line (cohort B; n = 46) brivanib alaninate 800 mg once daily. Outcomes were compared between World Health Organization (WHO) criteria and (retrospectively by) mRECIST by independent review. The relationship between on-study AFP changes and outcome was analyzed in patients with elevated AFP at baseline.
RESULTS
Response rates were higher with mRECIST versus WHO criteria in cohorts A (25.5% vs. 7.3%) and B (10.9% vs. 4.3%). Progressive disease (PD) as assessed by mRECIST was associated with a very short median overall survival (OS; cohort A, 2.8 months; cohort B, 5.3 months); PD as assessed by WHO criteria reflected a mixed population of patients with better outcomes. mRECIST responders tended to have a>50% AFP decrease during therapy. In cohorts A and B pooled, an early AFP response (>20%or >50% decline from baseline within the first 4 weeks) was not associated with longer median OS.
CONCLUSIONS
Tumor response as assessed by mRECIST differed from that by WHO criteria, with mRECIST possibly identifying true nonresponders with a poor prognosis. Many patients had AFP decreases correlating with tumor shrinkage, yet an association with long-term benefit was unclear. mRECIST and on-treatment AFP levels are being explored further with brivanib in HCC.

Therapeutic options for advanced, unresectable hepatocellular carcinoma (HCC) have changed dramatically over the last 3 years. While surgical resection, orthotropic liver transplantation, and localized therapeutic options such as ablation, radiation therapy, and embolization remain therapeutics of choice in localized disease, systemic therapy is the only option in advanced, metastatic HCC. Since the United States Food and Drug Administration (US FDA) approval of sorafenib in 2008, targeted therapies such as sunitinib, tivantinib, brivanib, erlotinib, and linifanib; monoclonal antibody- bevacizumab showed no meaningful improvement in treatment of HCC. However, with improved understanding on the molecular pathophysiology and tumor heterogeneity of HCC, we have made progress in expanding the therapeutic options in advanced HCC. Targeted therapy with lenvatinib, cabozantinib, and regorafenib; monoclonal antibody ramucirumab; immunotherapies nivolumab and pembrolizumab have demonstrated promising results in the clinical trials. The current work outlines the molecular mechanisms and tumorigenesis of HCC, a detailed discussion of the trial results of the approved therapies in HCC, future perspectives and potential options to overcome the challenges of systemic therapy in HCC.

Review
Non-alcoholic fatty liver disease is the most common liver disorder worldwide, and its progressive form non-alcoholic steatohepatitis (NASH) is a growing cause of liver cirrhosis and hepatocellular carcinoma (HCC). Lifestyle changes, which are capable of improving the prognosis, are hard to achieve, whereas a pharmacologic therapy able to combine efficacy and safety is still lacking. Looking at the pathophysiology of various liver diseases, such as NASH, fibrosis, cirrhosis, and HCC, the process of angiogenesis is a key mechanism influencing the disease progression. The relationship between the worsening of chronic liver disease and angiogenesis may suggest a possible use of drugs with antiangiogenic activity as a tool to stop or slow the progression of the disorder. In this review, we highlight the available preclinical data supporting a role of known antiangiogenic drugs (e.g., sorafenib), or phytotherapeutic compounds with multiple mechanism of actions, including also antiangiogenic activities (e.g., berberine), in the treatment of NASH.

BACKGROUND
Brivanib is an oral, tyrosine kinase inhibitor against vascular endothelial growth factor (VEGF) and fibroblast growth factor receptor (FGFR). We studied its efficacy and tolerability in persistent or recurrent cervical cancer patients.
METHODS
Eligible patients had at least one prior cytotoxic regimen for recurrence and with measurable disease. Brivanib 800mg was administered orally every day (1cycle=28days) until disease progression or prohibitive toxicity. Primary endpoints were progression-free survival (PFS) >6months and objective tumor response.
RESULTS
Of 28 eligible and evaluable women enrolled, 11 (39%) had primary surgery and 25 (89%) had prior radiation. Eighteen (64%) received one prior cytotoxic treatment and 10 (36%) had 2 prior regimens. Twelve (43%) had >2cycles of brivanib with 4 (14%) receiving >10cycles (range: 1-20). Seven (25%) patients had PFS >6months (90% CI: 7.3%-33.9%). Two (7%) (90% CI: 1.3%-20.8%) patients had partial tumor response with duration of 8 and 22months and 12 (43%) had stable disease. The median PFS was 3.2months (90% CI: 2.1-4.4). The median overall survival was 7.9months (90% CI: 6.1-11.7). More common grade 3 adverse events were hypertension, anemia, hyponatremia, hyperglycemia, elevated liver enzymes, nausea, headache, and colon hemorrhage. Grade 4 adverse events included sepsis and hypertension.
CONCLUSIONS
Based on early results of this phase II trial, brivanib was well tolerated and demonstrated sufficient activity after first stage but trial was stopped due to lack of drug availability.

RATIONALE
Hepatocellular carcinoma (HCC) is one of the most frequent causes of cancer-related death worldwide. Its poor prognosis is due to the high invasiveness of the disease and limited efficacy of available treatments.
PATIENT CONCERNS
We reported an HCC patient who developed lung metastases 1 year after HCC resection. Sorafenib was then initiated; however, disease progression was noted 3 months later. Sorafenib therapy was initially maintained due to lack of effective alternatives, but disease progression continued.
DIAGNOSES
HCC patient with lung metastases, and pulmonary portal, and mediastinal lymph node metastases (stage IVB).
INTERVENTIONS
Brivanib alaninate was used alone as second-line therapy.
OUTCOMES
All metastases showed increased size on radiographic imaging approximately 3 months after brivanib alaninate was initiated. However, 2.5 months later, the lung metastases significantly decreased in size or disappeared. The pulmonary portal, and mediastinal lymph node metastases also significantly decreased in size. At 9.5 months after brivanib alaninate initiation, the pulmonary portal, and mediastinal lymph node metastases nearly disappeared, and the lung metastases continued to decrease in size. Alpha fetoprotein (AFP) level showed the same change pattern as the tumor-response observed on radiographic imaging. The total duration of brivanib alaninate treatment was 11 months, which was stopped due to repeated grade 2 thrombocytopenia. The other side effects were tolerable. Fifteen months after initiation of brivanib alaninate, the patient remained in very good condition without evidence of disease progression.
LESSONS
Brivanib alaninate alone as second-line therapy showed excellent antitumor efficacy for an HCC patient with numerous lung and lymph node metastases. It may exert its antitumor effects in a delayed-onset fashion. We suggest that patients receive brivanib alaninate for a long duration to fully determine its efficacy.
