Detailed Description
Hepatocellular carcinoma (HCC) is the fifth most common solid cancers worldwide and the third leading cause of cancer-related death. Early stage HCC can be cured by surgical removal or non-surgical ablation procedures, albeit a high recurrence rate up to 75% in 5 years remains an unsolved problem. On the other hand, in patients with unresectable HCC, the "standard therapy" is still under intensive clinical investigations. In patients without portal vein occlusion/thrombosis or extrahepatic metastasis, namely Barcelona Clinical Liver Cancer (BCLC) Stage B, transcatheter arterial chemoembolization (TACE) is believed to be an effective palliative treatment. The beneficial effect of TACE on overall survival has been mild to moderate as reviewed in a previous study. Thus, TACE is generally considered a "palliative" therapy. TACE induces tumor necrosis but at the same time, it also induces angiogenesis owing to the increases of hypoxia-inducible factors and endothelial growth factors to trigger regrowth of tumors.
It has been known that GALNT14 genotype is associated with treatment responses. Patients with GALNT14 "TT" genotype response well to both TACE and chemotherapy.
A new immunotherapy is directed against Globo H, a carbohydrate antigen that is expressed at high levels on the surface of a variety of tumor cells. These Globo H-specific antibodies can effectively induce complement dependent cytotoxicity (CDC) as well as antibody-dependent cell-mediated cytotoxicity (ADCC) by IgM and IgG, respectively, together with other cellular immune responses to kill tumors. In the clinical setting, Globo H has been evaluated as the target of active immunotherapy in a few clinical trials including an ongoing Phase II/III trial of adagloxad simolenin/OBI-821 sponsored by OBI Pharma, Inc., as a potential treatment for stage IV metastatic breast cancers and possibly other cancer types expressing Globo series TACAs. Although vaccination with adagloxad simolenin/OBI-821 did not improve progression-free survival (PFS) in patients with previously treated metastatic breast cancer, in a post-hoc analysis, patients who developed a humoral immune response to Globo H had a longer PFS than those who did not, indicating that adagloxad simolenin/OBI-821 treatment could be of benefit when an antibody response can be developed.
Furthermore, overexpression of tumor-specific antigen Globo H can contribute to enhanced tumor angiogenesis and tumor-associated immune suppression, and in turn, positively correlate with tumor aggressiveness and poor survival in patients. In the present study, only "non-TT" (less favorable) groups will be enrolled and the patients will be randomized to examine the hypothesis that the TACE + adagloxad simolenin/OBI-821 treatment is beneficial in the BCLC class B, advanced HCC patients.

Adagloxad simolenin (OBI-822) is a glyco-conjugated protein comprised of a carbohydrate tumor antigen. Globo H allyl glycoside is covalently linked to a carrier protein KLH, presented in a dominant trimer form with molecular weight between 1200-1395 kDa., to form Adagloxad simolenin (OBI-822) (Globo H-KLH) OBI-821 is a saponin based adjuvant structurally similar to descriptions found in the literature for another adjuvant, QS-21. Adagloxad simolenin will be mixed with OBI-821 before administration. |
