Active disease defined as moderate to severe active CD at Screening defined by all of the following:\n\n   * Evidence of mucosal inflammation, defined as SES-CD ≥ 6 (≥ 4 for subjects with isolated ileal disease), and;\n   * CDAI total scores ≥ 220\n5. Subject on treatment with corticosteroids may be included if they meet the following:\n\n   * prednisone or equivalent dose ≤ 20 mg\u002Fday; or\n   * budesonide ≤ 9 mg\u002Fday; or\n   * has been on a stable dose for at least 7 days prior to TRX103 dose.\n6.

Prior therapies may be inclusive of any combination of the following:\n   * TNF-alpha inhibitors\n   * IL-12\u002F23 inhibitors\n   * Anti-integrins\n   * JAK inhibitors Failure of therapies are defined as either non-response (primary failure), complete loss of response (secondary failure) or intolerant to therapy at a dose indicated for CD.\n   * Primary failure is defined as:\n\n     * When a subject does not achieve a response after having received the induction doses of a CD approved drug per prescribing information. Induction period is defined as 12-weeks.\n     * A response is defined as CDAI score that reduces by ≥ 100-point from Baseline or by Physician assessment.\n   * Secondary failure, or relapse defined as:\n\n     * Subjects who respond to the therapy or achieves remission after an induction regimen per prescribing information, but subsequently lose response or relapses during maintenance treatment.\n     * Relapse is defined as an increase in the CDAI score from maintenance of ≥ 100 points and a CDAI score \\> 220, and\u002For SES-CD score ≥ 6 (or ≥ 4 if isolated ileal disease) or by Physician assessment.\n   * Intolerant to therapy, defined as:\n\n     * When a subject is unable to cope with the side effects or mechanism of actions of the treatment and\u002For experiences unacceptable side effects when dosed at appropriate therapeutic levels.\n7. Absence of uncontrolled bacterial, viral, or fungal infection at time of enrollment.\n8. Subjects must be able to understand and sign informed consent and be willing and able to complete all specified procedures and visits.\n\nExclusion Criteria:\n\n1. Prior organ transplant, or allogeneic bone marrow, peripheral blood, or cord blood stem cell transplant. Note: Blood transfusion are not exclusionary if it occurred ≥ 3 years (- 3 months) of TRX103 infusion.\n2.

Received any approved treatment for CD within the designated washout period (including off-label use of approved therapies) as per the protocol.\n4. Strictures, active fistulae (including perianal), or abscess by computed tomography (CT) or magnetic resonance enterography (MRE) or Endoscopy within 6 months of Screening.\n5. Positive serology for HIV.\n6. Positive hepatitis-B surface antigen. Subject may be included if they are HBV PCR negative.\n7. Hepatitis C virus (HCV RNA detectable in any subject with anti-HCV antibodies).\n8. Subject with active or chronic recurring infections or untreated latent Tuberculosis (TB).\n9. Current diagnosis of ulcerative colitis (UC), indeterminate colitis or CD isolated to colon only (the colitis must be related to CD and inclusive of ileal with or without colonic involvement).\n10.

Subject with surgical bowel resection within the past 3 months prior to Screening, or a history of \\> 2 bowel resections. Note: Surgery for temporary use of an ostomy bag or reconnection of the gut post colostomy use is not considered exclusionary, nor considered as part of the surgical resection if during the reconnection removal of tissue is required to facilitate reattachment.\n12. Subjects that are pregnant, breast feeding, or aim to become pregnant during the 12 month study period. (Subjects, males and females, must agree to use a highly effective method of contraception).\n13.
