Hospitalization for any reason within 60 days of randomization. 8. Participation in any clinical research study evaluating another investigational drug or therapy within 30 days of the investigational drug, whichever is longer, prior to the randomization visit. 9. Live/attenuated vaccinations within 12 weeks of randomization or during the study. 10. Tuberculosis vaccination within the last year. 11. Previous exposure to any other biological agent within 12 months of randomization. 12. History of a hypersensitivity reaction to doxycycline or other tetracyclines. 13. Recent travel (within 12 months of randomization) to areas endemic for parasitic helminthes, such as developing countries, particularly in Africa and the tropical and subtropical regions of Asia. 14.
