Brief summary: The purpose of this study is to determine whether infliximab is effective on fat-free mass in the treatment of patients with moderate to severe COPD suffering from cachexia.

Detailed description: COPD is a multicomponent disease characterized by abnormal inflammatory response of the lungs to noxious particles that accompanied by systemic effects like weight loss, muscle wasting, reduced functional capacity and health status. A persistent systemic inflammatory response reflected by enhanced levels of acute phase proteins like C-reactive protein (CRP) or pro-inflammatory cytokines such as tumor necrosis factor (TNF) - α, is present in COPD. There are several studies that indicate that an increased systemic inflammator response is associated with weight loss, cachexia (loss of fat-free muscle mass), physical functioning and health status.

Cachexia associated with systemivc inflammation can not always readily be overcome by nutritional intervention alone.

The hypothesis of this study is that infliximab therapy (3 infusions with 5 mg/kg infliximab or placebo 1:1 on week 0, 2 and 6) will increase fat-free mass relatively to placebo by decreasing inflammation. Secondary endpoints are: lung function, muscle function, exercise capacity and health status. On week 8, 12 and 26 follow-up measurements will be done.

Eligibility criteria: Inclusion Criteria:

1. COPD acording GOLD with FEV1/FVC ratio \< 70%, and post-bronchodilator FEV1 \> 20% but \< 80% of predicted and an FEV1 of \>500ml.

   Exclusion Criteria:
   1. \> 11% increase in FEV1 as % of predicted after a fixed dose of bronchodilator (200 µg inhaled salbutamol)
   2. \>12% variation between screening and baseline FEV1 assessments
   3. FEV1 \< 500 ml
   4. Patients with asthma as main component of their obstructive airways disease
   5. Moderate or severe exacerbation of COPD within previous 2 months
   6. History or clinical signs of severe cor pulmonale, or pulmonary hypertension, severe right or left sided cardiac failure, serious arrhythmias, myocardial infarction or cardiac interventions within 6 months of screening.

   Exclusion criteria on echocardiogram:

   Exclude patients with right-sided heart defects, as defined by any 1 of the following 3 echocardiography criteria:

   3. Right ventricular (RV)-right atrial (RA) pressure drop of \>50 mmHg Exclusion of patients with left ventricular ejection fraction (LV EF) of \<40%, as measured on echocardiography.

   Exclusion criteria on electrocardiogram:

   Exclude patients with the following arrhythmias identified on electrocardiography (ECG):
   1. Fast atrial fibrillation at ventricular rate of \>90/min
   2. Atrial-ventricular conduction delay of grade 2 or higher : excludes 2nd and 3rd degree heart block.
   3. Left bundle branch block, with QRS complex \>120msec.
   4. Ventricular arrhythmias: ventricular tachycardia and trigeminy.
