Details and patient eligibility

About

This is an prospective, interventional, non-randomized multicenter phase II study to evaluate the safety, tolerability and efficacy of Cabozantinib as a second-line therapy (after one prior systemic therapy) in patients with intermediate to advanced HCC (BCLC B/C) and concomitant impaired liver function CP score B7-8. Subjects who meet all study eligibility criteria will receive Cabozantinib 40 mg daily orally. Subjects will receive Cabozantinib as long as they continue to experience clinical benefit in the opinion of the Investigator or until there is unacceptable toxicity or the need for subsequent systemic anti-cancer treatment or liver directed local anti-cancer therapy. Treatment may continue in this fashion after radiographic progression as long as the Investigator believes that the subject is still receiving clinical benefit from Cabozantinib and that the potential benefit of continuing Cabozantinib outweighs potential risk. In addition, all subjects will be treated with best supportive care. This excludes systemic anti-cancer therapy and liver-directed local anti-cancer therapy.

4. Availability of a recent (up to 28 days old) CT/MRI images of thorax and abdomen
5. Subject's HCC is not amenable to a curative treatment approach (e.g., transplant, surgery, radiofrequency ablation) corresponding to BCLC classification B/C
6. Progression or toxicities following one prior systemic therapy for HCC
7. Recovery to ≤ grade 1 from toxicities related to any prior treatments, unless the adverse events are clinically non-significant and/or stable on supportive therapy
8. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2

10. Adequate renal function, based upon meeting the following laboratory criteria within 7 days before enrollment: serum creatinine ≤ 1.5 × upper limit of normal or calculated creatinine clearance ≥ 40 mL/min (using the Cockcroft-Gault equation)
11. Liver function Child-Pugh (CP) score B7-8
12. ALBI (albumin-bilirubin) grade 1-2
13. Alanine aminotransferase (ALT) and aspartate amino-transferase (AST) < 7.0 × upper limit of normal (ULN) within 7 days before enrollment
14. Antiviral therapy per local standard of care if active hepatitis B (HBV) infection
15. Capability to understand and comply with the protocol requirements (e.g. sufficient knowledge of German language to answer the questionnaires, ability to swallow intact tablets).

Main exclusion criteria:

1. Fibrolamellar carcinoma or mixed hepatocellular cholangiocarcinoma

2. Receipt of more than 1 prior systemic therapy for advanced HCC. Additional prior systemic therapies used as adjuvant therapy are allowed.

3. Any type of anti-cancer agent (including investigational) within 2 weeks before enrollment

4. Radiation therapy within 4 weeks (2 weeks for radiation for bone metastases) or radionuclide treatment (e.g., I-131 or Y-90) within 6 weeks of enrollment. Subject cannot be enrolled if there are any clinically relevant ongoing complications from prior radiation therapy.

5. Prior Cabozantinib treatment

6. Known brain metastases or cranial epidural disease unless adequately treated with radiotherapy and/or surgery (including radiosurgery) and stable for at least 3 months before enrollment. Eligible subjects must be without corticosteroid treatment at the time of enrollment.

7. Concomitant anticoagulation, at therapeutic doses, with anticoagulants such as warfarin or warfarin-related agents, low molecular weight heparin (LMWH), thrombin or activated coagulation factor X (FXa) inhibitors, or antiplatelet agents (e.g., clopidogrel). Low-dose aspirin for cardioprotection (per local applicable guidelines), low-dose warfarin (≤ 1 mg/day), and low-dose LMWH are permitted.

8. The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:

   • Cardiovascular disorders including: Symptomatic congestive heart failure, instable angina pectoris, or serious cardiac arrhythmias, uncontrolled hypertension defined as sustained BP > 150 mm Hg systolic, or > 100 mm Hg diastolic despite optimal antihypertensive treatment, stroke (including TIA), myocardial infarction, or other ischemic event within 6 months before enrollment, thromboembolic event within 3 months before enrollment. Subjects with thromboses of portal/hepatic vasculature attributed to underlying liver disease and/or liver tumor are eligible
   • Gastrointestinal (GI) disorders including those associated with a high risk of perforation or fistula formation: tumors invading the GI tract, active peptic ulcer disease, inflammatory bowel disease, diverticulitis, cholecystitis, symptomatic cholangitis or appendicitis, acute pancreatitis or acute obstruction of the pancreatic duct or common bile duct, or gastric outlet obstruction; abdominal fistula, GI perforation, bowel obstruction, intra-abdominal abscess within 6 months before enrollment, Note: Complete healing of an intra-abdominal abscess must be confirmed prior to enrollment
   • Major surgery within 2 months before enrollment. Complete healing from major surgery must have occurred 1 month before enrollment. Complete healing from minor surgery (e.g., simple excision, tooth extraction) must have occurred at least 7 days before enrollment. Subjects with clinically relevant complications from prior surgery are not eligible
   • Cavitating pulmonary lesion(s) or endobronchial disease
   • Lesion invading a major blood vessel (e.g., pulmonary artery or aorta)
   • Clinically significant bleeding risk within 3 months of enrollment including the following: hematuria, hematemesis, hemoptysis of > 0.5 teaspoon (> 2.5 mL) of red blood, or other signs indicative of pulmonary hemorrhage, or history of other significant bleeding if not due to reversible external factors
   • Other clinically significant disorders such as: Active infection requiring systemic treatment, known infection with human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)-related illness; serious non-healing wound/ulcer/bone fracture; malabsorption syndrome; uncompensated/symptomatic hypothyroidism; requirement for hemodialysis or peritoneal dialysis; history of solid organ transplantation

9. Subjects with untreated or incompletely treated varices with bleeding or high risk for bleeding are excluded with the following clarification: subjects with history of prior variceal bleeding must have been treated with adequate endoscopic therapy without any evidence of recurrent bleeding for at least 6 months prior to study entry and must be stable on optimal medical management (e.g. non-selective beta blocker, proton pump inhibitor) at study entry.

10. Women who are pregnant, nursing, or who plan to become pregnant while in the trial.

11. Women of child-bearing potential (WOCBP) and men who are able to father a child, unwilling to be abstinent or use highly effective methods of birth control that result in a low failure rate of less than 1% per year when used consistently and correctly beginning at informed consent, for the duration of study participation and for at least 4 months after last dose of the study drug. Because oral contraceptives might possibly not be considered as "effective methods of contraception" during the treatment with Cabozantinib, they should be used together with another method, such as a barrier method.

12. Currently receiving any other investigational agent or received an investigational agent within 30 days (or within 5 times the half-life of this agent or its relevant metabolites, the longer period will apply) before the first dose of Cabozantinib.

13. Hepatic encephalopathy Grad I-IV according to CP classification (≥ 2 points) and West Haven Criteria

14. Moderate or severe ascites according to CP classification (≥ 3 points)

15. Corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms within 7 days before enrollment.
