The primary objective of the study is to assess the time to progression (TTP) in patients with advanced HCC treated with Icaritin .

Icaritin is a newly discovered small molecular compound which is high selective ERa36 modulators ,the preclinical PK&PD and toxicity studies showed it can inhibit the growth of HCC cancer cells both in vitro and in vivo, combining clinical data perhaps it will be a very promising new drug to treat hepatocellular carcinoma (HCC) by targeting this nongenomic pathway. Shenogen decided to further investigate the efficacy and safety of Icaritin and to explore potential gene targets for treating HCC.

The results of phase I study showed Icaritin has good safety and tolerance. The biological availability of Icaritin after meal is high and the half-life is relatively short.

The phase Ib study enrolled 28 subjects. Among the 18 HCC subjects, 12 subjects received treatment in the oral administration group with 600 mg once, twice per day, after meal 30 minutes, 6 subjects received treatment in the oral administration group with 800 mg once, twice per day, after meal 30 minutes. The results showed that in the 600mg group there are 12 HCC patients whose therapeutic efficacy is evaluable now, one case of PR (10%), 5 cases of SD (50%) and 4 cases of PD (40%) were observed.Safety data showed that totally 24 AEs are probably related to investigational drug. Among them, 19 AEs are grade I, 5 AEs are grade II, no grade III or above AE.

Inclusion Criteria:

Patients may be entered in the study only if they meet all of the following criteria:

1. The age is between 18 and 75.

2. Patients who have HCC which should be histologically or cytologically confirmed. At least one lesion, not previously treated ( can be accurately measured at baseline as ≥ 10 mm in the longest diameter with computed tomography (CT) per RECIST 1.1)

3. Patients who cannot accept or is not willing to have surgery or any interventional therapy via hepatic artery, or had surgery and any Interventional therapy via hepatic artery more than 4 weeks with disease progression, and cannot tolerate Sorafenib or Oxaliplatin doublet chemotherapy or cannot use or refused to use them

4. Child-Pugh status A or B (≤7) ( Either albumin or haemachrome is >2)

5. ECOG PS: 0 or 1.

6. Patients who have a life expectancy of at least 12 weeks.

7. Patients who have not received chemotherapy and target therapy. If patients received radiation therapy or surgery, the treatment should be at least 4 weeks prior to enrollment and any AE and wounds during the treatment should be recovered. If patient received adjuvant chemotherapy, the treatment should be at least 6 months prior to enrollment.

8. Meet following laboratory parameters:

   • Haematology ( no blood transfusion or Blood products or Hematopoietic growth factor within 14 days)

     1. Hemoglobin ≥ 90 g/dL
     2. Neutrophil cell count≥1.5 × 10^9/L
     3. Platelet count ≥ 80 × 10^9/L

   • Clinical chemistry,

     1. Albumin ≥ 29 g/dL (no albumin transfusion or blood product within 14 days)
     2. ALT and AST < 5 × ULN
     3. Total bilirubin ≤ 1.5 × ULN
     4. Serum creatinine ≤ 1.5 × ULN

9. If HBV-DNA≥10^4, anti-virus therapy should be used until HBV-DNA< 10^4

10. Patients is willing to participate in the study with good compliance and must have given written informed consent prior to any study specific screening

11. Patients who did not participate in any other study 4 weeks prior to enrollment and all adverse events occurs before should be recovered.

Exclusion Criteria:

Patients who meet with any below criterion should not be included in the study:

3. Patients who have hypertension and blood pressure are not well controlled after treatments with antihypertensive drugs (systolic pressure > 150mmHg, diastolic pressure >100mmHg); patients who have grade II or higher myocardial ischemia or myocardial infarction and poorly controlled arrhythmia (including QTC interval≥ 450ms) and grade III-IV cardiac insufficiency according to NYHA criteria; Ultrasound Cardiogram on heart: LVEF (left ventricular ejection fraction)<50%;
4. Patients are incapable of swallow, or have chronic diarrhea or intestinal obstruction, which significantly affects administration and absorption of study drug;
5. Patients potentially have gastrointestinal hemorrhage (such as local active ulcer foci, occult blood in stools ++ or even higher), previous medical records of alimentary tract hemorrhage within six months;
6. Patients who have central nervous system metastasis;
7. Patients who have coagulation disorder (prothrombin time > 16s, activated partial thromboplastin time > 43s, thrombin time >21s, fibrinogen< 2g/L), subjects showing hemorrhagic tendency or accepting thrombolytic or anticoagulant therapy;
8. Patients who have psychiatric disorders or previous medical history of psychotropic drug abuse;
9. Patients who have seroperitoneum with clinical symptoms, requring remedial abdominal paracentesis or drainage, or Child-Pugh score ≥2.
