Have no signs or symptoms suggestive of active TB upon medical history and/or physical examination. c. Have had no recent close contact with a person with active TB or, if there has been such contact, will be referred to a physician specializing in TB to undergo additional evaluation and, if warranted, receive appropriate treatment for latent TB prior to or simultaneously with the first administration of study agent. d. Within 1 month prior to the first administration of study agent, either have a negative tuberculin skin test, as outlined in Appendix C, or have a newly identified positive tuberculin skin test during screening in which active TB has been ruled out and for which appropriate treatment for latent TB has been initiated either prior to or simultaneously with the first administration of study agent. e.
