Trial Outcomes & Findings for Tykerb Evaluation After Chemotherapy (TEACH): Lapatinib Versus Placebo In Women With Early-Stage Breast Cancer (NCT NCT00374322)

NCT ID: NCT00374322

Last Updated: 2014-08-18

Results Overview

DFS=interval between the date of randomization and the date of the first occurrence of an objective disease recurrence, a second primary cancer, or death from any cause. The date of the event is the earliest date of the occurrence of any of the following: local recurrence (LR) following mastectomy; LR in ipsilateral breast following lumpectomy; regional recurrence; distant recurrence; contralateral breast cancer, including ductal carcinoma in situ; other second primary cancer (excluding squamous or basal cell carcinoma of the skin, melanoma in situ, carcinoma in situ of the cervix, or lobular carcinoma in situ of the breast); death from any cause without a prior event. Par. who started additional anti-cancer adjuvant therapy prior to the recurrence of their disease were to be censored. Par. who did not withdraw from the study and did not experience a specified event or death were to be censored (follow-up ongoing) at the last visit date available at which progression was assessed.

Participant Flow

Women with early-stage ErbB2-overexpressing breast cancer who had not been previously treated with trastuzumab were enrolled in this Phase III study. Women who subsequently had no clinical or radiologic evidence of disease were enrolled after completion of primary neoadjuvant/adjuvant chemotherapy.

The study consisted of a Screening Period, a 1-year Treatment Period, and a Follow-up (FU) Period of up to 5 years after the date of study drug withdrawal/completion, for disease status/survival. A total of 3161 eligible participants (par.) (of the 3166 enrolled) were randomized, out of which 3147 par. received at least one dose of study treatment.

The SF-36 v2 is a self-administered, health-related quality of life (QoL) metric. It is a 36-item questionnaire designed to measure 8 domains of functional health status and well-being: physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health. Each domain is scored from 0 (poorer health) to 100 (better health).The PCS score is a summary score representing overall physical health, which is derived from the 8 domain scores. As with each domain score, the PCS score ranges from 0 to 100; higher scores represent better health. Change from Baseline was calculated as the post-Baseline score minus the Baseline score. Missing post-Baseline data were imputed using the last observation carried forward (LOCF) method. The scores were analyzed using an analysis of covariance (ANCOVA) model, adjusting for Baseline sub-scale score, treatment, and country. Positive changes from Baseline indicate improvement.

SECONDARY outcome

Timeframe: At Baseline and every 3 months thereafter up to Month 12/Early Withdrawal Visit

Population: Safety Population (SP): all randomized participants (par.) who received \>=1 dose of randomized treatment. Only those par. available (n=X, X in the category titles) at the specified time points were analyzed. Different par. may have been analyzed for different parameters, so the overall number of par. analyzed reflects everyone in the SP.

The hematology parameters assessed were: basophils (Bs) in giga (10\^9) per liter (GI/L) and in percentage (%), eosinophils (Eo) in GI/L and %, hematocrit, hemoglobin, lymphocytes (Lmph) in GI/L and %, monocytes (Mono) in GI/L and %, platelet count, Red Blood Cell (RBC) count, total neutrophil count (TNC) in GI/L and %, and White Blood Cell (WBC) count. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline value" was based on results recorded at any scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) is presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. Data for the primary analysis (conducted in 2011) are reported.

Outcome measures

SECONDARY outcome

Timeframe: At Baseline and every 6 weeks thereafter up to Month 12/Early Withdrawal Visit

Population: Safety Population (primary analysis \[conducted in 2011\]). Only those participants available (represented as n=X, X in the category titles) at the specified time points were analyzed. Different participants may have been analyzed for different parameters, so the overall number of participants analyzed reflects everyone in the Safety Population.

The clinical chemistry parameters assessed were: alanine amino transferase (ALT), albumin, alkaline phosphatase (ALP), aspartate amino transferase (AST), bicarbonate, blood urea nitrogen (BUN), bone alkaline phosphatase (Bone ALP), calcium, chloride, creatinine, creatinine clearance (Cr. Clearance), creatinine clearance estimated (Cr. Clrnc. est.), glucose, potassium, sodium, total bilirubin (Total Bln), total protein, urea, and uric acid. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline" value was based on results recorded at scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) was presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm.

Timeframe: From the first dose of study treatment up to 12 months

Population: Safety Population. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. Data for the primary analysis (conducted in 2011) are reported.

Non-laboratory toxicities are defined as adverse events (AEs). The number of partcipants with any treatment-emergent AE of the indicated toxicity grade are summarized. Toxicity grading was according to the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 as follows: Grade 1=mild; Grade 2=moderate; Grade 3=severe; Grade 4=life threatening; Grade 5=death. The events that were not given a toxicity grade are categorized as "Not Applicable."

Population: Safety Population (SP). Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. Data for the primary analysis (conducted in 2011) are reported.

A cardiac event is classified as a primary cardiac endpoint (PCE) or a secondary cardiac endpoint (SCE). PCE is defined as: cardiac death (cardiac death due to heart failure, myocardial infarction, or arrhythmia;or probable cardiac death defined as sudden, unexpected death within 24 hours of a definite or probable cardiac event); severe symptomatic congestive heart failure (CHF) (as per New York Heart Association \[NYHA\] Class III or IV and an absolute decrease in left ventricular ejection fraction \[LVEF\] of more than 10 percentage points from Baseline and to a left ventricular ejection fraction \[LVEF\] value below 50%). SCE is defined as asymptomatic or mildly symptomatic cardiac events (NYHA Class I or II) and a significant decrease in LVEF, defined as an absolute decrease in LVEF of more than 10 percentage points from Baseline and to an LVEF value below 50%.
