An International Phase 2 Study Of SU011248 In Patients With Inoperable Liver Cancer

The study will consist of two parts. In Part 1 the study will start enrolling 38 patients and then further 25 patients up to a total of 63 eligible patients. If the study gives good results it can be expanded to a total of 160 patients. SU011248 will be administered orally daily for 4 weeks followed by a 2-week rest at a starting dose of 50 mg [milligrams] with provision for dose reduction based on tolerability. All patients will receive repeated cycles of SU011248 until disease progression, occurrence of unacceptable toxicity, or other withdrawal criteria are met. After discontinuation of treatment, patients will be followed up in order to collect information on further antineoplastic therapy and survival

Primary outcomes

  1. Best Overall Response

    Time frame: From start of treatment until Day 28 of Cycle 1, Day 28 of Cycles thereafter

    Number of subjects with best overall response. Complete response (CR)=disappearance of all target lesions. Partial Response (PR)= ≥30% decrease in sum of longest dimensions of lesions taking as reference baseline sum longest dimensions. Progressive disease (PD)= ≥ 20% increase in sum of longest dimensions of lesions taking as a reference smallest sum of the longest dimensions since treatment start, or the appearance of ≥ 1 new lesion. Stable disease (SD)=neither shrinkage for PR or increase for PD taking as reference smallest sum of longest dimensions since treatment start.

  2. Objective Response (CR or PR)

    Time frame: From start of treatment until Day 28 of Cycle 1, Day 28 of Cycles thereafter

    Number of patients with objective response: confirmed CR or confirmed PR according to RECIST. CR was defined as the disappearance of all target lesions. A PR was defined as a ≥30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. To be assigned a status of PR or CR, changes in tumor measurements in patients with responding tumors had to have been confirmed by repeat studies that were performed ≥ 4 weeks after the criteria for response were first met.

    Number of patients with Clinical Benefit Response: confirmed CR, confirmed PR, or SD for at least 12 weeks on study according to RECIST. CR=disappearance of all target lesions.
