Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Patients with basal-cell carcinoma of the skin completely resected outside the perineal region can be included 11. Current or recent (within 6 months prior to the Screening visit) history of severe, progressive, and/or uncontrolled hepatic, haematological, gastrointestinal (other than CD), renal, endocrine, pulmonary, cardiac, neurological or psychiatric disease that may result in patients increased risk from study participation and/or lack of compliance with study procedures 12.

Pregnant or breastfeeding women 19. Patients who do not wish to or cannot comply with study procedures 20. Patients currently receiving, or having received any investigational drug within 3 months prior to Screening visit 21. Patients previously treated with Cx601 or other allogeneic stem-cell therapy cannot be enrolled into this clinical study 22. Any major surgery of the GI tract (including one or more segments of the colon or terminal ileum) within 6 months prior the screening or any minor surgery of the GI tract within 3 months prior to screening 23. Patients who had local perianal surgery other than drainage for the fistula within 6 months prior to the Screening visit, or those who may need surgery in the perianal region for reasons other than fistulas at the time of inclusion in the study 24. Contraindication to the anaesthetic procedure.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
The current multicentre phase III study is proposed to evaluate the efficacy and safety of Cx601 compared to placebo for the treatment of complex perianal fistula(s) in patients with Crohn's disease at Week 24 with a follow-up period up to 52 weeks. The primary efficacy analysis, will be conducted at Week 24 timepoint. The double blind design will be maintained up to Week 52 (both patient and investigator) by a specific blinding for study treatment administration and for evaluating its efficacy . The study will follow an add-on design, patients receiving any ongoing concomitant medical treatment, at stable doses at the time of screening, for the Crohn's disease (CD) will be allowed to continue it throughout the study. Study treatments will be allocated, on a 1:1 ratio, by central randomization through interactive web response system (IWRS).
