• Provide written informed consent for the study participation, and agree to continue in the study
• Received a single or bilateral lung transplant
• Agreement to use contraception; according to the FDA Office of Women's Health (http://www.fda.gov/birthcontrol), there are a number of birth control methods that are more than 80% effective. Female participants of child-bearing potential must consult with their physician and determine the most suitable method(s) from this list to be used for the duration of the study. Those who choose oral contraception must agree to use a second form of contraception after administration of study drug for a period of 1 year after the last dose of study drug

• Current treatment with alkylating agents such as cyclophosphamide
• History of gastrointestinal (GI) tract perforation
• History of inflammatory bowel disease except fully excised ulcerative colitis
• Any history of diverticulitis (event if not perforated) or confirmed diverticular bleeding. (Diverticulosis is not an exclusion).
• Patients with a platelet count \< 100,000/mm\^3 (last measurement within 7 days prior to enrollment)
• Patients with an absolute neutrophil count (ANC) \< 2,000/mm\^3 (last measurement within 7 days prior to enrollment)
• Patients with Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) levels \>3 times upper limit of normal
• Patients who use illegal drugs
• Smoking or vaping within 6 months of listing for transplant
• Use of investigational drugs within 4 weeks prior to enrollment
• Any condition that in the opinion of the site Principal Investigator (PI) introduces undue risk by participating in this study Randomization:
• Recipient of multi-organ or tissue transplants
• Clinically stable, without clinical evidence of untreated infection
• Received a live virus vaccine within 30 days prior to randomization
• Received treatment to deplete HLA antibodies before transplantation to improve the possibility of transplantation
