Accelerated versus standard epirubicin followed by cyclophosphamide, methotrexate, and fluorouracil or capecitabine as adjuvant therapy for breast cancer (UK TACT2; CRUK/05/19): quality of life results from a multicentre, phase 3, open-label, randomised, controlled trial.

BACKGROUND: Adjuvant chemotherapy for patients with early breast cancer improves outcomes but its toxicity affects patients' quality of life (QOL). The UK TACT2 trial investigated whether accelerated epirubicin improves time to recurrence and if oral capecitabine is non-inferior to cyclophosphamide, methotrexate, and fluorouracil (CMF) for efficacy with less toxicity. Results showed no benefit for accelerated epirubicin and capecitabine was non-inferior. As part of the QOL substudy, we aimed to assess the effect of chemotherapies on psychological distress, physical symptoms, and functional domains. METHODS: TACT2 was a multicentre, phase 3, open-label, parallel-group, randomised, controlled trial done in 129 UK centres. Participants were aged 18 years or older with histologically confirmed node-positive or high-risk node-negative invasive primary breast cancer, who had undergone complete excision, and due to receive adjuvant chemotherapy. Patients were randomly assigned (1:1:1:1) to four cycles of 100 mg/m2 epirubicin either every 3 weeks (standard epirubicin) or every 2 weeks with 6 mg pegfilgrastim on day 2 of each cycle (accelerated epirubicin), followed by four 4-week cycles of either CMF (600 mg/m2 cyclophosphamide intravenously on days 1 and 8 or 100 mg/m2 orally on days 1-14; 40 mg/m2 methotrexate intravenously on days 1 and 8; and 600 mg/m2 fluorouracil intravenously on days 1 and 8 of each cycle) or four 3-week cycles of 2500 mg/m2 capecitabine (1250 mg/m2 given twice daily on days 1-14 of each cycle). The randomisation schedule was computer generated in random permuted blocks, stratified by centre, number of nodes involved (none vs 1-3 vs ≥4), age (≤50 years vs >50 years), and planned endocrine treatment (yes vs no). QOL was one of the secondary outcomes and is reported here. All patients from a subset of 44 centres were invited to complete QOL questionnaires (Hospital Anxiety and Depression Scale [HADS] and European Organisation for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire 30-item core module [QLQ-C30] and Quality of Life Questionnaire breast module [QLQ-BR23]) at baseline, end of standard or accelerated epirubicin, end of CMF or capecitabine, and at 12 and 24 months after randomisation. The QOL substudy prespecified two coprimary QOL outcomes assessed in the intention-to-treat population: overall QOL (reported elsewhere) and HADS total score. Prespecified secondary QOL outcomes were EORTC QLQ-C30 subscales of physical function, role function, and fatigue and EORTC QLQ-BR23 subscales of sexual function and systemic therapy side-effects. This trial is registered with ISRCTN, ISRCTN68068041, and ClinicalTrials.gov, NCT00301925. FINDINGS: From Dec 16, 2005, to Dec 5, 2008, 4391 patients (20 [0·5%] of whom were male) were enrolled in TACT2; 1281 (85·8%) of 1493 eligible patients were included in the QOL substudy. Eight (0·6%) participants in the QOL substudy were male and 1273 (99·4%) were female. Median follow-up was 85·6 months (IQR 80·6-95·9). Analysis was performed on the complete QOL dataset (as of Sept 15, 2011) when all participants had passed the 24-month timepoint. Prerandomisation questionnaires were completed by 1172 (91·5%) patients and 1179 (92·0%) completed at least one postrandomisation questionnaire. End-of-treatment HADS depression score (p=0·0048) and HADS total change score (p=0·0093) were worse for CMF versus capecitabine. Accelerated epirubicin led to worse physical function (p=0·0065), role function (p<0·0001), fatigue (p=0·0002), and systemic side-effects (p=0·0001), but not sexual function (p=0·36), compared with standard epirubicin during treatment, but the effect did not persist. Worse physical function (p=0·0048), sexual function (p=0·0053), fatigue (p<0·0001), and systemic side-effects (p<0·0001), but not role functioning (p=0·013), were seen for CMF versus capecitabine at end of treatment; these differences persisted at 12 months and 24 months. INTERPRETATION: Accelerated epirubicin was associated with worse QOL than was standard epirubicin but only during treatment. These findings will help patients and clinicians make an informed choice about accelerated chemotherapy. CMF had worse QOL effects than did capecitabine, which were persistent for 24 months. The favourable capecitabine QOL compared with CMF supports its use as an adjuvant option after neoadjuvant chemotherapy in patients with triple-negative breast cancer.

24-h bronchodilator efficacy of single doses of indacaterol in Japanese patients with asthma: a comparison with placebo and salmeterol.

BACKGROUND: Indacaterol is a novel, inhaled once-daily ultra-long-acting beta-2 agonist under development as a fixed-dose combination with an inhaled corticosteroid (ICS) for asthma treatment. This study evaluated the 24-h bronchodilator efficacy of indacaterol in Japanese patients with asthma. METHODS: Randomised, placebo-controlled, 5-period crossover study. Patients with persistent asthma (18-75 years, FEV(1) 50-85% predicted, ≥12% and 200 mL FEV(1) reversibility) receiving ICS were randomised to double-blind single dose indacaterol 150, 300, or 600 µg or placebo, with open-label salmeterol 50 µg twice-daily for one day in the 5(th) period. Primary endpoint was FEV(1)AUC(22-24h). RESULTS: Of 41 randomised patients (48.8% male; mean age: 47.8 years), 39 completed. All indacaterol doses showed significantly higher FEV(1)AUC(22-24h) than placebo (P<0.001), with treatment-placebo differences of 180, 220, and 260 mL for indacaterol 150, 300, and 600 µg, respectively (salmeterol-placebo difference 170 mL; P < 0.001). For individual time-point FEV(1), all indacaterol doses were superior to placebo from 5 min to 24h post-dose (P < 0.001). Compared with salmeterol, all indacaterol doses were superior from 5 to 30 min (P < 0.05); in addition indacaterol 300 µg and 600 µg were superior at a number of subsequent time points. Changes in safety parameters with indacaterol were similar to placebo. All indacaterol doses were well tolerated. CONCLUSION: Single dose indacaterol provided sustained 24-h bronchodilation with a faster onset of action than salmeterol and a good overall safety and tolerability profile in Japanese patients with asthma. These results are consistent with data from Caucasian populations.

Bronchodilator efficacy of single doses of indacaterol in Japanese patients with COPD: A randomised, double-blind, placebo-controlled trial.

BACKGROUND: Indacaterol is an investigational, novel, inhaled once-daily ultra-long-acting beta-2 agonist for the treatment of chronic obstructive pulmonary disease (COPD). This study evaluated the 24-h bronchodilatory efficacy and safety of indacaterol in Japanese patients with COPD. METHODS: This Phase-II, randomised, placebo-controlled, crossover study comprised four double-blind, single-dose treatment periods (washout between periods: 14-28 days). Japanese patients aged 40-75 years with moderate-to-severe COPD were randomised to receive single doses of indacaterol (150, 300, or 600 microg) or placebo via a single-dose dry-powder inhaler. Efficacy (primary endpoint: standardised FEV(1)AUC(22-24h)) and safety were assessed for 24 h post-dose in each treatment period. RESULTS: Of the 50 patients randomised (92% male; mean age, 67.2 years), 45 completed the study. Standardised FEV(1)AUC(22-24h) was significantly higher for all indacaterol doses as compared with placebo, with clinically relevant differences of 130, 160, and 170 mL for 150, 300, and 600 microg, respectively (P < 0.001). The improvement in FEV(1) was seen as early as 5 min post-dose with indacaterol and sustained for 24 h (P < 0.001 vs placebo at all time points). All indacaterol doses were well tolerated and showed no clinically meaningful effect on pulse rate, blood pressure, QTc interval, and laboratory parameters when compared with placebo. CONCLUSIONS: In the Japanese COPD population studied, single doses of indacaterol (150, 300, and 600 microg) provided sustained 24-h bronchodilation, with onset of action within 5 min post-dose. All doses were well tolerated. These results are consistent with data from Caucasian populations.
