Endoglin (CD105) is a type-1 integral transmembrane glycoprotein and coreceptor for transforming growth factor-β (TGF-β) ligands. The endoglin/TGF-β signaling pathway regulates hemostasis, cell proliferation/migration, extracellular matrix (ECM) synthesis and angiogenesis. Angiogenesis contributes to early progression, invasion, postoperative recurrence, and metastasis in hepatocellular carcinoma (HCC), one of the most widespread malignancies globally. Endoglin is overexpressed in newly formed HCC microvessels. It increases microvessel density in cirrhotic and regenerative HCC nodules. In addition, circulating endoglin is present in HCC patients, suggesting potential for use as a diagnostic or prognostic factor. HCC angiogenesis is dynamic and endoglin expression varies by stage. TRC105 (carotuximab) is an antibody against endoglin, and three of its clinical trials were related to liver diseases. A partial response was achieved when combining TRC105 with sorafenib. Although antiangiogenic therapy still carries some risks, combination therapy with endoglin inhibitors or other targeted therapies holds promise.

356 Background: PI3K/Akt/mTOR is a critical survival pathway in hepatocellular carcinoma (HCC) often correlated with poor prognosis. Rapamycin (sirolimus) and its analogue everolimus, are specific mTOR inhibitors that showed promising antitumor activity in preclinical models and clinical cases of HCC Aims: To evaluate the safety and efficacy of rapamycin in patients (pts) with advanced HCC after failure or intolerance to prior antiangiogenic therapy Methods: In this retrospective cohort, we analyzed consecutive patients with progressive HCC after 1 to 3 lines of treatment including at least sorafenib. All pts received oral rapamycin at 20 to 30 mg once a week. Adverse events (AEs) were assessed using NCI-CTCAE v3.0, and tumor response was evaluated according to RECIST criteria. Results: Nine patients (F/M: 1/8) with compensated liver cirrhosis (Child A, n = 6; Child B7, n = 2) or no cirrhosis (n=1) and histologically proven HCC were included in this study. Overall, therapy with rapamycin was well tolerated. Most common toxicities were asthenia (grade 1-2: 5 pts) anaemia (all grade: 5 pts; grade 3: 2 pts ) and thrombocytopenia (grade 1-2: 2 pts). Liver function deterioration was observed in 2 pts with advanced cirrhosis (Child B7). Radiological evaluation was available in 6 pts. No objective tumor response was observed however stable disease ≥ 3 months was observed in 4 cases. Moreover, 2 pts showed stable disease at 6 months. Prolonged stabilization under rapamycin was observed in pts who were previously controlled at least for 6 months with sorafenib. Rapamycin was discontinued due to disease progression in 7/8 pts, toxicity in 1/8 pts. One pt shows ongoing long-lasting disease stabilization (8 + months). Conclusions: Rapamycin displayed an acceptable safety profile and may achieved disease stabilization in patients with heavily pretreated advanced HCC.
