Trial Outcomes & Findings for Study of Hsp90 Inhibitor AUY922 for the Treatment of Patients With Refractory Gastrointestinal Stromal Tumor (NCT NCT01404650)

NCT ID: NCT01404650

Last Updated: 2016-10-04

Results Overview

Measured from time of randomization until objective tumor progression or death; assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria. Progressive disease (PD) defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest (nadir) sum since the treatment started, or the appearance of one or more new lesions.

Participant Flow

This multi-center trial evaluated AUY922 monotherapy as treatment for patients with gastrointestinal stromal tumor (GIST) refractory to, or intolerant of, imatinib and sunitinib. Between Dec 2011 and Jan 2015, 25 patients enrolled in the trial. Thirty-four patients (34) were planned to be enrolled but enrollment stopped early due to slow accrual.

PRIMARY outcome

Timeframe: At 6 and 12 weeks then every 9 weeks thereafter until progression or intolerable toxicity, up to 4 years.

Measured from time of randomization until objective tumor progression or death; assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria. Progressive disease (PD) defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest (nadir) sum since the treatment started, or the appearance of one or more new lesions.

Progression-free Survival (PFS)
3.9 months
Interval 2.5 to 5.3

SECONDARY outcome

Timeframe: At 6 and 12 weeks then every 9 weeks thereafter until progressive disease or intolerable toxicity, for up to 4 years.

Population: Of 25 patients enrolled, 4 patients were not evaluable for response due to treatment discontinuation prior to first disease evaluation.

Defined as the proportion of complete and partial responses, assessed per RECIST v1.1. Complete response (CR) defined as a disappearance of all lesions; partial response (PR) defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking the baseline sum LD as reference. Stable Disease (SD) defined as neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify for progressive disease, taking as reference the smallest (nadir) sum LD since start of treatment.

Evidence of survival was obtained by clinic visit or telephone contact from the time of first dose until death from any cause.
