About this study

Official title: A Prospective Study for the Assessment of the Long-term Safety and Efficacy of Cx401 in Patients Taking Part in the FATT-1 Trial

The purpose of this extension is to investigate and confirm the long-term (6 months) safety and efficacy of the preceding FATT-1 trial [ClinicalTrials.gov identifier: NTC00475410], which studied patients with perianal fistula treated having received adipose-derived adult stem cell (ASC)and/or fibrin glue.

Read the detailed description

Complex perianal fistulas are a source of great distress for suffers. Treatment options are limited and surgery is often associated with incontinence and recurrence.

The biological properties of stem cells derived from adult tissues make them candidates for the treatment of pathologies requiring tissue regeneration or in diseases where the healing process is altered.

This study aims to evaluate the safety and efficacy of patients having participated within a preceding multicenter, placebo-controlled, phase 3 study [ClinicalTrials.gov identifier: NTC00475410]. The present extension aims to collect safety and efficacy data for up to 12 month from initial administration.

Fistula closure is defined as absence of suppuration through the external orifice with complete re-epithelization of the external orifice and absence of collections >2cm directly related to the fistula tract treated, as measured by MRI.

Being tested
ASCs, Fibrin glue
Keywords
Complex perianal fistula, Adipose-derived adult stem cells, Fibrin glue

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ASCsDrug

    Also called Cx401 (company code), Ontaril®

    Intralesional injection of adult-stem-cells at a dose of 20 and 40 million.

  • Fibrin glueDrug

    After curettage, the fistulous tract was sealed with fibrin glue.

What is being measured

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

  1. Cumulative incidence of adverse events (clinical or laboratory) attributed to the study therapy in the preceding FATT-1 randomized trial (CX401 or fibrin glue)

    Measured: 6 months (since last visit in FATT-1 trial)

Secondary outcomes (1)
  1. Closure of the fistula (defined as suppuration through the external opening of the fistula spontaneously and on pressure, complete re-epithelization of the external opening in the clinical evaluation and absence of collections >2 cm in MRI)

    Measured: 6 months (since last visit of FATT-1 trial)

The record says: finished, as of the sponsor's last update on 12 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cumulative incidence of adverse events (clinical or laboratory) attributed to the study therapy in the preceding FATT-1 randomized trial (CX401 or fibrin glue) (time frame: 6 months (since last visit in FATT-1 trial)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01020825, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
