Inclusion criteria: Patients meeting all of the following criteria will be considered for enrollment to the trial: - Ambulatory male or female patients = 18 years - Patients must have histologically confirmed diagnosis - Tumor tissue is mandatory for pre-treatment evaluation (baseline) (fresh biopsy during 4-weeks screening time preferred. Archived specimen is only acceptable, if = 6 months old. Baseline tumor biopsy samples must be available prior to the first dose of DKN-01. - Tumor tissue (FFPE) must be received by central histopathology laboratory for correlative studies - Patients with activated WNT/ß-catenin signaling identified by glutamine synthetase staining (high positive staining in tumor tissue) by an approved lab. Positive staining must be confirmed prior to first dose of DKN-01. - Child-Pugh score grade 1 (NCI CTCAE v4.03) related to any prior HCC treatment must be resolved.

Patients with chronic HBV infection must have HBV DNA < 2000 IU/mL and must be on antiviral therapy. o HCV-HCC: Active or resolved HCV infection as evidenced by detectable HCV RNA or antibody - Acceptable liver function: o Total bilirubin =2.0 × upper limit of normal (ULN). o Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =5 × ULN. - Acceptable renal function: o Calculated creatinine clearance =50 mL/min using the Cockcroft and Gault Method (Cockroft and Gault 1976). - Acceptable hematologic status: o Neutrophil Granulocyte =1500 cells/µl. o Hemoglobin = 8,5 g/dL (= 5,28 mmol/l)(transfusion permitted within 30 days of study entry). o Platelet count =75,000 cells/µl. - Acceptable coagulation status: o INR = 1.7 and no active bleeding, (i.e., no clinically significant bleeding within 14 days prior to first dose of study therapy - Female subjects who are post-menopausal (defined as spontaneous amenorrhea for at least a year) or permanently sterilized (e.g. bilateral oophorectomy, hysterectomy, bilateral salpingectomy) can participate in the trial - Women of child bearing potential must have a negative serum or urine pregnancy test within 7 days prior to first dose of DKN-01. The minimum sensitivity of the pregnancy test must be 25 IU/L or equivalent units
Exclusion criteria
Exclusion criteria: Patients presenting at least one of the following criteria will not be enrolled in the trial: - - Patients with the following histology of hepatocellular cancer are not eligible for enrollment: fibrolamellar carcinoma or mixed hepatocellular cholangiocarcinoma. - New York Heart Association Class III or IV cardiac disease, myocardial infarction within the past 6 months, or unstable arrhythmia. - Specific cardiac preconditions : Fridericia-corrected QT interval (QTcF) >470 msec (female) or >450 msec (male), or history of congenital long QT syndrome. Any ECG abnormality that in the opinion of the Investigator would preclude safe participation in the study; patients with pacemakers where QTc is not a reliable measure will require an evaluation by a cardiologist to exclude co-existing cardiac conditions which would prohibit safe participation in the study. - Active, uncontrolled bacterial, viral, or fungal infections, within 7 days of study entry requiring systemic therapy. - human immunodeficiency virus (HIV) positive, - History of major organ transplant (i.e., heart, lungs, liver, or kidney). - History of autologous/allogenic bone marrow transplant. - Serious non-malignant disease that could compromise protocol objectives in the opinion of the Investigator and/or Sponsor. - Pregnancy or nursing. - Major surgical procedures, open biopsy or significant traumatic injury within 4 weeks prior to treatment start (minor procedures within 1 week) - History of osteonecrosis of the hip or evidence of structural bone abnormalities in the proximal femur on magnetic resonance imaging (MRI) scan that are symptomatic and clinically significant. Degenerative changes of the hip joint are not exclusionary. Screening of asymptomatic patients is not required. - Symptomatic central nervous system (CNS) malignancy or metastasis. Patients with treated CNS metastases are eligible provided their disease is radiographically stable, asymptomatic, and they are not currently receiving corticosteroids and/or anticonvulsants. Screening of asymptomatic patients without a history of CNS metastases is not required. - Known osteoblastic bone metastasis. Screening of asymptomatic patients without a history of metastatic bone lesions is not required. - Medical or psychological conditions that would jeopardise an adequate and orderly completion of the trial. - Thrombotic or embolic events (except HCC tumor thrombus <pVT4) within the past 6 months (including cerebrovascular accidents) - Evidence of portal hypertension with bleeding esophageal or gastric varices within the past 6 months - Patients with portal thrombosis = pVT4 Medication Related - prior systemic therapy for HCC - Currently receiving any other investigational agent or received an investigational agent within last 30 days prior to first dose or within 5 times the half-life of this agent before the first dose of study treatment. - Previously treated with an anti-DKK1 therapy. - Treatment with strong inducers of CYP3A4 within 7 days prior to first dose (including Cyclosporin, Erythromycin, Ketoconazole, Itraconazole, Quinidine, Phenobarbital salt with Quinidine, Ritonavir, Valspodar, Verapamil, St John's wort, rifampicin). - Significant allergy to a pharmaceutical therapy that, in the opinion of the Investigator, poses an increased risk to the patient. - History of hypersensitivity to the investigational medicinal product or to any drug with similar chemical structure or to any excipient present in the pharma

Primary
| Measure | Time frame |
|---|---|
| Main Objective: Part A: Evaluation of safety and tolerability using frequency and severity of adverse events to establish the recommended phase II dose (RP2D) of DKN-01 when administered as monotherapy for 8 weeks and in combination with sorafenib for 8 weeks in adult patients with HCC. Part B: To assess the time to progression (TTP1, TTP2) in treatment naïve patients with advanced HCC after treatment with DKN-01 monotherapy until PD1 and in combination with sorafenib until PD2. TTP1 and TTP2 will be determined according to mRECIST ;Secondary Objective: Part A: - To assess safety of the doses of 300 mg and 600 mg DKN-01 given as mono- and as combination therapy - To characterize the pharmacokinetics of DKN-01 when administered at the dose of 300 mg and 600 mg as monotherapy and in combination with sorafenib Part B: - To assess tumor response with DKN-01 monotherapy and in combination with sorafenib - To assess the clinical safety of DKN-01 monotherapy and in combination with sorafenib at the dose used for part B ;Primary end point(s): Part A: Primary variables are the absolute and relative frequencies of adverse events. Part B: Time to progression (TTP2). The TTP2 is defined as the time from the first dosing until PD2. Tumor progression is assessed by mRECIST criteria (modified Response Evaluation Criteria in Solid Tumors). TTP1 i.e. the time from the first dosing until PD1 (objective progression with DKN-01 monotherapy) will also be evaluated. ;Timepoint(s) of evaluation of this end point: Part A: after 2 cycles of monotherapy and 2 cycles of combination therapy with sorafenib Part B: at time of PD1 and PD2 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Part A: Serum DKN-01 levels in patients Part B: - To assess overall survival (OS), progression free survival (PFS1, PFS2), the objective response rate (ORR), and the disease control rate (DCR) with DKN-01 as a monotherapy and in combination with sorafenib at end of study - Duration of disease control with DKN-01 - Adverse Events as assessed by NCI CTCAE v5.0 ;Timepoint(s) of evaluation of this end point: Part A: after 2 cycles of monotherapy and 2 cycles of combinationtherapy with sorafenib Part B: at time of PD1 and PD2 | — |
