Title: A Phase III Multi-center, Double-blind, Placebo-controlled, Parallel Group 24-Week Study to Assess the Efficacy and Safety of Two Dose Regimens of Liquid Certolizumab Pegol as Additional Medication to Methotrexate in the Treatment of Signs and Symptoms of Rheumatoid Arthritis and in Prevention of Joint Damage in Patients With Active Rheumatoid Arthritis Who Have an Incomplete Response to Methotrexate.
Brief Summary: A 24 week study in which patients are given study medication and assessed for signs and symptoms of rheumatoid arthritis. X-rays are performed to assess the progress of joint damage during the study.

* Patients must have active RA disease as defined by:

  * 9 tender joints at Screening and Baseline.
  * 9 swollen joints at Screening and Baseline. and fulfilling 1 of the following 2 criteria during the screening period:
  * 30 mm/hour ESR (Westergren), or CRP \>15 mg/L.
* Patients must have received treatment with MTX (with or without folic acid) for at least 6 months prior to the Baseline visit. The dose of MTX and route of administration must have been stable for at least 2 months prior to the baseline visit. The minimum stable dose of MTX allowed is 10 mg weekly.
* Patients must be willing to complete an X-ray of the hands and feet 24 weeks after randomization even if they are no longer receiving study treatment in the present study, provided they have not withdrawn their informed consent.
