Trial Outcomes & Findings for Long-term Follow-up Study With Darvadstrocel in the Treatment of Complex Perianal Fistula (NCT NCT04075825)

NCT ID: NCT04075825

Last Updated: 2025-04-23

Results Overview

An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered an investigational medicinal product; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product.

Participant Flow

Participants took part in the study at various investigative sites globally from 05 November 2019 to 02 April 2024.

Participants diagnosed with Complex Perianal Fistula in Crohn's Disease (CD) who completed the Week 52 visit in the parent study ADMIRE-CD II (Cx601-0303, NCT03279081) were enrolled. Participants remained in the treatment group (placebo or darvadstrocel) to which they were assigned in ADMIRE-CD II study.

An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered an investigational medicinal product; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product.

AESIs are AEs that are not solicited local or systemic AEs, they are predefined AEs that require close monitoring and prompt reporting to the sponsor. Protocol pre-specified AESIs included immunogenicity/allo-immunoreactions, tumorigenicity, ectopic tissue formation and fistula/abscess. In addition, ad hoc AESIs of anaphylactic reaction, hypersensitivity, and malignancy.

Population: Safety Analysis Set included all participants enrolled in the LTE study, according to the actual treatment they received in the ADMIRE-CD II study. . Overall number analyzed is the number of participants who were in combined remission at Week 52 of ADMIRE-CD II.

Relapse is defined as participants who were in combined remission at Week 52 of ADMIRE-CD II and who have either reopening of any of the treated fistula(s) external openings with active drainage as clinically assessed or, the development of a perianal fluid collection \>2 cm of the treated perianal fistulas confirmed by centrally read magnetic resonance imaging (MRI) assessment. Combined remission at Week 52 was defined as clinically assessed closure of all treated external openings that were draining at baseline of ADMIRE-CD II, despite gentle finger compression, and absence of collection(s) \>2 cm (in at least 2 dimensions) of the treated perianal fistula(s) confirmed by blinded central MRI assessment. Percentages were rounded off to the nearest second decimal place.

Population: Safety Analysis Set included all participants enrolled in the LTE study, according to the actual treatment they received in the ADMIRE-CD II study. Overall number analyzed is the number of participants with data available at ADMIRE-CD II Baseline. Number analyzed is the number of participants with data available for analyses at the specified timepoint.

The PDAI is a scoring system to evaluate the severity of perianal CD. From the 5-item instrument, only 'discharge' was used for this outcome measure. Each category is graded on a 5-point Likert scale ranging from no symptoms (score of 0) to severe symptoms (score of 4); a higher score indicates more severe disease.
