Trial Outcomes & Findings for An International Phase 2 Study Of SU011248 In Patients With Inoperable Liver Cancer (NCT NCT00247676)

NCT ID: NCT00247676

Last Updated: 2010-02-18

Results Overview

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.

Participant Flow

This study was designed using a Simon 2-stage design with the objective response rate as the primary efficacy endpoint. Enrollment was halted after the first stage because the minimum number of responders by Response Evaluation Criteria in Solid Tumors (RECIST) needed to continue into Stage 2 was not reached.

Population: Intent-to-treat (ITT) population includes all patients enrolled in the study that received at least 1 dose of study medication.

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.

PRIMARY outcome

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

Population: ITT

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.

Blood samples for the assessment of CECs and circulating CEPs were planned to be obtained for subjects in Part 1 of the study, and for a subset of subjects in Part 2 of the study to complete the angiogenic profile of unresectable hepatocellular carcinoma, in addition to the soluble protein evaluation.

Population: ITT. Tumor biopsy results were collected optionally in 5 subjects; however, no evaluations were performed.

Provision of previously collected tumor paraffin blocks (or at least 5-10 4-micron slides prepared from the paraffin block) for correlative laboratory analysis was optional. For all subjects showing OR on study, it was highly recommended to provide previously collected paraffin blocks (or at least 5-10 4-micron slides prepared from the paraffin block). These samples were to be analyzed for markers that may be associated with tumor proliferation or angiogenesis.

Plasma concentrations of VEGF that may be associated with tumor proliferation or angiogenesis were collected from a subset of subjects and analyzed by e nzyme-linked immunosorbent assay (ELISA). Soluble protein values: Baseline concentration (pM) and ratio to Baseline at each timepoint; ratio to Baseline = plasma concentration of soluble protein at timepoint / concentration of soluble protein at baseline. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

Timeframe: Cycle 1 (Days 1, 14, 28), Cycle 2 (Days 1, 28), Cycle 5 (Day 28)

Population: ITT

Plasma concentrations of sVEGFR-2 that may be associated with tumor proliferation or angiogenesis were collected from a subset of subjects and analyzed by ELISA. Soluble protein values: Baseline concentration (pM) and ratio to Baseline at each timepoint; ratio to Baseline = plasma concentration of soluble protein at timepoint / concentration of soluble protein at baseline). Samples below the limit of quantitation and samples with insufficient volume available were excluded.
