The ACT-ONE trial, a multicentre, randomised, double-blind, placebo-controlled, dose-finding study of the anabolic/catabolic transforming agent, MT-102 in subjects with cachexia related to stage III and IV non-small cell lung cancer and colorectal cancer: study design
Aims Cachexia, the wasting disorder associated with a wide
range of serious illnesses including cancer, is a major cause of morbidity and mortality. There is currently no widely approved therapeutic agent for treating or preventing
cancer-associated cachexia. Colorectal cancer and nonsmall
cell lung cancer have relatively high incidences of cachexia, approximately 28% and 34%, respectively.
Neurohormonal overactivity has been implicated in the
genesis and progression of cachexia and beta receptor
antagonism has been proposed as a potential therapy.
MT-102, a novel anabolic/catabolic transforming agent,
has a multi-functional effect upon three potential pharmacological targets in cancer cachexia, namely reduced
catabolism through non-selective β-blockade, reduced
fatigue, and thermogenesis through central 5-HT1a
antagonism and increased anabolism through partial β-2
receptor agonism.
Methods At least 132 male and female patients, aged
between 25 and 80 years with a confirmed diagnosis of
late-stage non-small cell lung cancer or colorectal cancer,
with cachexia will be randomised to either one of the two
MT-102 doses or placebo in a 3:1:2 ratio (MT-102
10 mg BD−1/MT-102 2.5 mg BD/placebo). Patients will
continue on study treatment for maximally 16 weeks. The
primary endpoint, to be analysed by assigned treatment
group, will be body weight change over 16 weeks. For this
endpoint, the study has 85% power (0.05% significance
level) to detect per 4-week period a mean change of −0.8 kg
in the placebo group and 0 kg in the high-dose MT-102
arm. The first patient was randomised in February 2011 and
patient recruitment is expected to continue until mid-2012.
Perspective The ACT-ONE trial is designed to test whether
the anabolic/catabolic transforming agent MT-102 will
positively impact on the rate of change of body weight in
cancer cachexia, thereby evaluating a novel therapeutic
strategy in this hitherto poorly treatable condition. A
separate ACT-TWO trial will recruit patients who complete
the ACT-ONE trial and remain on randomised double-blind
medication. Participants in ACT-TWO will be followed for
an additional period with a separate primary endpoint
2q36.3 is associated with prognosis for oestrogen receptor-negative breast cancer patients treated with chemotherapy
Large population-based registry studies have shown that breast cancer prognosis is inherited. Here we analyse single-nucleotide polymorphisms (SNPs) of genes implicated in human immunology and inflammation as candidates for prognostic markers of breast cancer survival involving 1,804 oestrogen receptor (ER)-negative patients treated with chemotherapy (279 events) from 14 European studies in a prior large-scale genotyping experiment, which is part of the Collaborative Oncological Gene-environment Study (COGS) initiative. We carry out replication using Asian COGS samples (n=522, 53 events) and the Prospective Study of Outcomes in Sporadic versus Hereditary breast cancer (POSH) study (n=315, 108 events). Rs4458204-A near CCL20 (2q36.3) is found to be associated with breast cancer-specific death at a genome-wide significant level (n=2,641, 440 events, combined allelic hazard ratio (HR)=1.81 (1.49-2.19); P for trend=1.90 × 10 â ̂'9). Such survival-associated variants can represent ideal targets for tailored therapeutics, and may also enhance our current prognostic prediction capabilities
Assessment of variation in immunosuppressive pathway genes reveals TGFBR2 to be associated with prognosis of estrogen receptor-negative breast cancer after chemotherapy
Introduction: Tumor lymphocyte infiltration is associated with clinical response to chemotherapy in estrogen receptor (ER) negative breast cancer. To identify variants in immunosuppressive pathway genes associated with prognosis after adjuvant chemotherapy for ER-negative patients, we studied stage I-III invasive breast cancer patients of European ancestry, including 9,334 ER-positive (3,151 treated with chemotherapy) and 2,334 ER-negative patients (1,499 treated with chemotherapy). Methods: We pooled data from sixteen studies from the Breast Cancer Association Consortium (BCAC), and employed two independent studies for replications. Overall 3,610 single nucleotide polymorphisms (SNPs) in 133 genes were genotyped as part of the Collaborative Oncological Gene-environment Study, in which phenotype and clinical data were collected and harmonized. Multivariable Cox proportional hazard regression was used to assess genetic associations with overall survival (OS) and breast
