About this study

Official title: A Follow-up of a Phase 3 Study to Evaluate the Long-term Safety and Efficacy of Darvadstrocel in the Treatment of Complex Perianal Fistula in Subjects With Crohn's Disease Who Have Participated in ADMIRE II Study

The main aim is to follow-up on long term side effect and symptom improvement of Darvadstrocel in the treatment of complex perianal fistula in adults. Participants will not receive any drug in this study.

Read the detailed description

The drug being tested in this study is called darvadstrocel (Cx601). Darvadstrocel is being tested to treat people who have complex perianal fistula in CD. This study will look at the long-term safety and efficacy of darvadstrocel in the treatment of complex perianal fistula in CD.

The study will enroll approximately 150 patients. Participants who received darvadstrocel or placebo in study ADMIRE-CD II (Cx601-0303, NCT03279081) and who have completed the 52 weeks of the study will be enrolled in this long-term extension study.

This multi-center study will be conducted worldwide. The overall time to participate in this study is 104 weeks (in addition to the 52 weeks on ADMIRE-CD II study). Participants will make multiple visits to the clinic and will be contacted by telephone every 3 months for a follow-up assessment. After unblinding of the ADMIRE-CD II study, the LTE study will be conducted as an open-label study. Participants will remain in the treatment group assigned in the ADMIRE-CD II study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment Emergent Adverse Events (TEAEs)

    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.

    Measured: Baseline (Week 0) up to Week 104 of this study (Week 52 up to Week 156 in relation to ADMIRE-CD II)

  2. Number of Participants With Treatment Emergent Serious Adverse Events (TESAEs)

    TEAE is defined as: any adverse event emerging/manifesting at or after the initiation of treatment with a study intervention/medicinal product or any existing event that worsens in either intensity/frequency following exposure to the study intervention/medicinal product. Serious adverse event (SAE) is an untoward medical occurrence, significant hazard, contraindication, side effect/precaution that at any dose: results in death, is life-threatening, required in-patient hospitalization/prolongation of existing hospitalization, results in persistent/significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant.

    Measured: Baseline (Week 0) up to Week 104 of this study (Week 52 up to Week 156 in relation to ADMIRE-CD II)

  3. Number of Participants With Specific Adverse Events of Special Interest (AESIs)

    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.

    Measured: Baseline (Week 0) up to Week 104 of this study (Week 52 up to Week 156 in relation to ADMIRE-CD II)

Secondary outcomes (7)
  1. Percentage of Participants Who Achieve Clinical Remission at Weeks 104 and 156 (After IMP Administration in ADMIRE-CD II Study)

    Clinical remission is defined as closure of all treated external fistula openings that were draining at baseline of ADMIRE-CD II despite gentle finger compression. Percentages were rounded off to the nearest second decimal place.

    Measured: At Weeks 52 and 104 of this study (Weeks 104 and 156 in relation to ADMIRE-CD II, respectively)

  2. Percentage of Participants Who Achieve Clinical Response at Weeks 104 and 156 (After IMP Administration in ADMIRE-CD II Study)

    Clinical response is defined as closure of at least 50% of all treated external fistula openings that were draining at baseline of ADMIRE-CD II despite gentle finger compression. Percentages were rounded off to the nearest second decimal place.

    Measured: At Weeks 52 and 104 of this study (Weeks 104 and 156 in relation to ADMIRE-CD II, respectively)

  3. Percentage of Participants With Relapse at Week 156 After Achieving 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.

    Measured: At Week 104 of this study (Week 156 in relation to ADMIRE-CD II)

  4. Percentage of Participants Who Achieve Combined Remission at Week 156 (After IMP Administration in ADMIRE-CD II Study)

    Combined remission of complex perianal fistula(s) is defined as the clinical assessment of 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 centrally read blinded MRI assessment. Percentages were rounded off to the nearest second decimal place.

    Measured: At Week 104 of this study (Week 156 in relation to ADMIRE-CD II)

  5. Percentage of Participants With New Anal Abscess in Treated Fistula at Week 156

    Percentages were rounded off to the nearest second decimal place.

    Measured: At Week 104 of this study (Week 156 in relation to ADMIRE-CD II)

  6. Change From Baseline of ADMIRE-CD II in Scores of Discharge Items of Perianal Disease Activity Index (PDAI) Score at Weeks 104 and 156

    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.

    Measured: From Baseline of ADMIRE-CD II up to Weeks 52 and 104 of this study (From Baseline up to Weeks 104 and 156 in relation to ADMIRE-CD II, respectively)

  7. Change From Baseline of ADMIRE-CD II in Scores of Pain Items of Perianal Disease Activity Index (PDAI) Score at Weeks 104 and 156

    The PDAI is a scoring system to evaluate the severity of perianal CD. From the 5-item instrument, only 'pain' 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.

    Measured: From Baseline of ADMIRE-CD II up to Weeks 52 and 104 of this study (From Baseline up to Weeks 104 and 156 in relation to ADMIRE-CD II, respectively)
