Study Of Lapatinib In Combination With Paclitaxel In The Treatment Of Newly Diagnosed Inflammatory Breast Cancer

27 mai 2017 mis à jour par: GlaxoSmithKline

A Phase II Study to Evaluate the Efficacy, Safety, and Pharmacodynamics of Lapatinib in Combination With Paclitaxel as Neoadjuvant Therapy in Patients With Newly Diagnosed Inflammatory Breast Cancer

This Study was designed to determine how effective and safe a new investigational drug, lapatinib, is in combination with paclitaxel in treating patients with newly diagnosed inflammatory breast cancer. Tumor tissue collected pre-treatment, following 14 days of treatment and at the time of surgical resection will be examined for pathologic response and biologic activity by IHC (immunohistochemistry) within the tumor. Treatment will consist of 14 days of lapatinib monotherapy followed by 12 weeks of combination therapy with lapatinib and paclitaxel. Blood samples for hematology and chemistry panels, MUGA/ECHO exams and physical exams will be performed throughout the study to monitor safety.

Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Percentage of participants with pathologic complete response rate (pCR)
Délai: Week 12
pCR was defined as the percentage of participants who achieved an assessment of complete response (CR) following pathologic review of resected tissue. CR was the disappearance of all target lesions. Participants in each cohort with unknown or missing response (i.e., those that did not undergo surgery) were included in the denominator when calculating the percentage. From an efficacy standpoint, the HER2+ population response was considered to be of special interest.
Week 12

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
Percentage of participants with pCR that underwent surgical resection
Délai: Week 12
pCR for participants that underwent surgical (surg) resection was defined as the percentage of participants within each cohort who achieved an assessment of CR following pathologic review of resected tissue. CR was the disappearance of all target lesions. Participants in each cohort that did not undergo surgical resection were excluded from the denominator when calculating the percentage. From an efficacy standpoint, the HER2+ population response was considered to be of special interest.
Week 12
Percentage of participants with objective response rate (ORR) at the end of study (Response evaluation criteria in solid tumor [RECIST])
Délai: Week 14
ORR at the end of the study was defined as the number of participants within each cohort who had a confirmed CR or partial response (PR) at the end of the study divided by the total number of participants enrolled in each cohort. CR was the disappearance of all target lesions. PR was at least a 30 percent decrease in the sum of the longest diameter of target lesions, taking as a reference, the Baseline sum longest diameter. Each participant's response was based on the investigator assessment of best response using RECIST criteria. Participants in each cohort with unknown or missing response was treated as non-responders; i.e. they were included in the denominator when calculating the percentage. From an efficacy standpoint, the HER2+ population was considered to be of special interest.

Délai: Week 14
ORR at the end of the study was defined as the number of participants within each cohort who had a confirmed CR or PR at the end of the study divided by the total number of participants enrolled in each cohort. CR was the disappearance of all target lesions. PR was at least a 30 percent decrease in the sum of the longest diameter of target lesions, taking as a reference, the Baseline sum longest diameter. The best response of the participant was defined by the 'Best' combined response (RECIST and Clinically Evaluable Skin Disease Criteria) provided there is no evidence of disease progression. Participants in each cohort with unknown or missing response was treated as non-responders; i.e. they were included in the denominator when calculating the percentage. From an efficacy standpoint, the HER2+ population was considered to be special interest.
Week 14
Percentage of participants with investigator-Assessed Best Response at the end of monotherapy phase (Day 14) (Clinically Evaluable Skin Disease Criteria)
Délai: Day 14
ORR at the end of the monotherapy phase was defined as the percentage of participants within each cohort who had a confirmed CR or PR at the end of lapatinib monotherapy (Day 14) divided by the total number of participants enrolled in each cohort. CR was the disappearance of all target lesions. PR was at least a 30 percent decrease in the sum of the longest diameter of target lesions, taking as a reference, the Baseline sum longest diameter. Each participant's response was based on the investigator assessment of best response using clinically evaluable skin disease criteria. Participants in each cohort with unknown or missing response was treated as non-responders; i.e. they were included in the denominator when calculating the percentage.

Change from Baseline in vital signs- Body temperature
Délai: Day 14, Week 1 and up to Week 24, surg resection and post treatment
Vitals signs (body temperature) were assessed from screening until the post treatment phase. Baseline was the most recent BP mean prior to the first dose of lapatinib. Change from Baseline was calculated as the mean at each visit minus the mean at Baseline.
Day 14, Week 1 and up to Week 24, surg resection and post treatment
Number of participants with abnormal electrocardiogram (ECG) findings
Délai: Screening and unscheduled
ECG was performed at screening and at unscheduled visits. Participants with abnormal clinically significant and abnormal not clinically significant ECG findings was reported.
Screening and unscheduled
Number of participants with change from Baseline in echocardiogram (ECHO) or Multi-gated angiogram (MUGA) results at any post Baseline visit
Délai: Screening, Week 8, 16, 24, post treatment
For ECHO and MUGA scans, the left ventricular ejection fraction (percent) was summarized for each scheduled assessment. Absolute change from Baseline was summarized according to the following categories: any increase, 0 to less than 20 percent decrease, >=20 percent decrease or >=20 percent decrease and below the lower limit of normal (LLN). Baseline was the most recent ECOG evaluation prior to the first dose of lapatinib. Change from Baseline was calculated as the value at the post treatment minus Baseline value.
