Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Summary

This trial investigates whether intravenous infusions of cells from the human placenta (PDA001) can reduce inflammation and improve symptoms in adults with moderate-to-severe Crohn's disease. Participants receive either one of three doses of PDA001 or a placebo, and researchers track safety and effectiveness over time. The goal is to see if this cell-based approach offers a new way to control this chronic digestive condition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
human placenta-derived cells (PDA001)
What this could lead to
If successful, this could point toward a new treatment option for people with moderate-to-severe Crohn's disease.
What could go wrong
This is an early Phase 2a study with only 50 participants, so results may not apply to everyone. The treatment may not work better than placebo, and side effects are possible.

Inclusion Criteria: 1. Males and females ages 18-75 years 2. Understand and voluntarily sign an informed consent 3. Able to adhere to the study visit schedule and other protocol requirements 4. Minimum weight of 50 kg 5. A female of childbearing potential (FCBP)† must have a negative urine pregnancy test at screening (Visit 1) and immediately prior to all doses of IP. In addition, sexually active FCBP must agree to use two of the adequate forms of contraception methods for the duration of the study and the follow-up period. A FCBP must agree to have pregnancy tests at least every 4 weeks during the study. Males (including those who have had a vasectomy) must agree to use barrier contraception (latex condoms) when engaging in reproductive sexual activity with FCBP for the duration of the study and the follow-up period. 6. Subject must have inflammatory CD 6 months prior to treatment and have confirmation of ongoing disease activity by colonoscopy or (other method) at screening 7. Subject must have a CDAI score \> 220 and \< 450 as assessed between Visit 1 and Visit 2 8. The Subject must have failed, i.e., had an inadequate response or lost response (recurrence of symptoms) to an agent, or documented intolerance to an agent at any time Exclusion Criteria: 1. Any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study 2. Any condition including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study A female of childbearing potential is a sexually mature woman who: 1. has not undergone a hysterectomy or bilateral oophorectomy 2. has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
