Trial Outcomes & Findings for Fulvestrant With or Without Ganetespib in HR+ Breast Cancer (NCT NCT01560416)

Last Updated: 2025-07-01

Results Overview

PFS based on Kaplan-Meier is defined as the time from study entry to the earliest documentation of disease progression (PD) or death. Participants alive without evidence of PD are censored at the date of last disease assessment. Participants who receive non-protocol anti-cancer therapy before disease progression are censored at time of last disease assessment.

Measure	ARM A - Fulvestrant Fulvestrant: 500 mg administered by intramuscular injection on days 1 and 15 of cycle 1, day 1 of cycle 2 and each subsequent cycle; cycle duration is 28 days Eligible participants on Arm A were allowed to crossover to Arm B upon disease progression. Treatment continued for Arm A participants until 2nd disease progression.	Arm B - Fulvestrant+Ganetespib Fulvestrant: 500 mg administered by intramuscular injection on days 1 and 15 of cycle 1, day 1 of cycle 2 and each subsequent cycle; cycle duration is 28 days Ganetespib: 200 mg/m2 administered intravenously on days 1, 8 and 15 of each 28 day cycle Arm B participants whose disease was at a minimum stable could elect to discontinue ganetespib after 6 cycles or stay on combination treatment until disease progression. Otherwise, Arm B participants taken off ganetespib for toxicity were to remain on single agent fulvestrant until disease progression.

SECONDARY outcome

Timeframe: AEs were assessed every cycle on treatment (weeks 2-3 on cycle 1). Median treatment duration was 4 cycles/~4 months on each arm. Maximum treatment duration was 41 cycles (Arm A) and 42 cycles (Arm B) which approximates 38 months.

All grade 3-4 adverse events (AE) with treatment attribution of possibly, probably or definite based on NCI Common Toxicity Criteria for Adverse Events version 4 (CTCAEv4) as reported on case report forms were counted to calculate the percentage of participants experiencing at least one treatment-related grade 3 or 4 AE of any type on treatment.

Grade 3-4 Toxicity Rate	100 percentage of participants	100 percentage of participants	100 percentage of participants

SECONDARY outcome

Timeframe: Disease was assessed radiographically every 2 cycles for year 1 and every 2-4 cycles thereafter on treatment. Maximum treatment duration was 41 cycles (Arm A) and 42 cycles (Arm B) which approximates 38 months.

Population: The analysis dataset is comprised of all enrolled participants.

ORR was defined as the percentage of participants with measurable disease at baseline achieving complete response (CR) or partial response (PR) based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.

Population: The analysis dataset is comprised of all enrolled participants.

CBR was defined as the percentage of participants with measurable disease at baseline achieving complete response (CR), partial response (PR), or stable disease (SD) for 24 weeks or longer based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PD is at least a 20% increase in sum LD of target lesions (smallest sum LD reference), new lesions, and/or unequivocal progression of existing non-target lesions. Stable disease (SD) is defined as any condition not meeting the above criteria. SD needed to be a minimum 24 weeks in duration.
