Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - RHB-104 (fixed-dose combination: 95 mg clarithromycin, 45 mg rifabutin, and 10 mg clofazimine)

Experimental: RHB-104 - patients on ACTIVE therapy in RHB-104-01 study - Subjects who were on the active therapy arm in the RHB-104-01 clinical study will continue to receive RHB-104 at 5 capsules twice a day in addition to the standard of care they received in the RHB-104-01 clinical study

Experimental: RHB-104 - patients on PLACEBO therapy in RHB-104-01 study - Subjects who were on the active therapy arm in the RHB-104-01 clinical study will receive RHB-104 at 5 capsules twice a day in addition to the standard of care they received in the RHB-104-01 clinical study. The RHB-104 will be ramped up beginning at 1 capsule twice per day in week 1 increasing to 2 capsules twice per day in week 2, 3 capsules twice per day in week 3, 4 capsules per day in week 4 and achieving 5 capsules per day for the remainder of the study.


Treatment: Drugs: RHB-104 (fixed-dose combination: 95 mg clarithromycin, 45 mg rifabutin, and 10 mg clofazimine)

Eligibility
Key inclusion criteria
* Signed fully informed consent (ICF) provided as per this protocol.
* Participation in RHB-104-01 for 26 weeks, and a Crohn's Disease Activity Index (CDAI) score of = 150 at Visit Week 26.

OR

* More than 26 weeks, with a CDAI =150 at Visit Week 26 and all subsequent visits, and subject is between Week 26 and 52 within 4 weeks (28 days) of site activation (e.g. Subject with CDAI = 249 at week 26 and who is at week 38 at the time of site's activation for RHB-104-04 has a 4-week window to be enrolled in the open label study via the Optional Screening Visit)
* Current treatment with at least one of the following therapies which may be discontinued by the investigator as clinically indicated after 8 weeks of open label RHB-104 treatment:

* Oral 5-acetyl salicylic acid (5-ASA) compounds
* Azathioprine or 6-mercaptopurine (6-MP) or methotrexate
* Infliximab or adalimumab OR Current treatment with corticosteroid therapy which must begin tapering after 4 weeks of treatment with open label RHB-104 (Refer to Appendix 13)
* White blood cell count = 3.5x109 at screening (RHB-104-01 Visit Week 26 visit or Optional Screening visit)
* Subject agrees to use the following effective contraceptive methods

* diaphragm, cervical cap, contraceptive sponge or condom) with spermicidal foam/gel/cream/suppository
* IUD (intrauterine device) /IUS (intrauterine system)
* progestogen injection (Depo-Provera®) throughout the study and for at least 6 weeks after last study drug administration, unless subject or partner of subject is post-menopausal or otherwise incapable of becoming pregnant by reason of surgery or tubal ligation, or has had a vasectomy.
