Expanded Access Protocol for STOMP-II Patients Who Were Unable to Receive Treatment Subsequent to Adipose Tissue Collection

An expanded access record providing AVB-114 in Perianal Fistula Due to Crohn's Disease, sponsored by Avobis Bio, LLC. Available. Per ClinicalTrials.gov, last updated 2024-07-19.

Study summary

The goal of this Expanded Access Protocol is to provide expanded access of AVB-114 to patients who had their fat tissue collected as part of a clinical trial (STOMP-II), but who were subsequently not treated with AVB-114 because they did not meet all eligibility criteria or the investigational product was not successfully manufactured.

Read the detailed description

AVB-114 is an autologous investigational product under evaluation in Seeded Cells on Matrix Plug Treating Crohn's Perianal Fistulas (STOMP-II; a prospective, multicenter, randomized, blinded outcome assessment, controlled, add-on therapy phase II study) for the treatment of complex perianal fistulas in subjects with Crohn's disease. EAP-STOMP2 is an expanded access protocol for patients who had adipose tissue collected per the STOMP-II protocol, but who were subsequently unable to receive AVB-114 treatment due to screen failure or product manufacturing issues and thus withdrew from the study. Patients will receive AVB-114 as deemed appropriate by investigator and Avobis Bio.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Provision of signed and dated ICF.
  2. Adipose tissue previously collected per the STOMP-II protocol, but were subsequently unable to receive AVB-114 treatment due to screen failure or product manufacturing issues and thus withdrew.
  3. Diagnosed with Crohn's disease and a target perianal fistula with one internal opening and at least one external opening.

Exclusion criteria

Exclusion Criteria:

  1. Suffer from any condition or illness that, in the opinion of the Investigator, would compromise patient safety.
  2. Pregnant, trying to become pregnant, or are breast feeding. Women of (WCBP) and males who have sexual partners that are WCBP must agree to use an adequate method of while participating in this EAP.
  3. Known allergies or to aminoglycosides.
  4. History of fat-directed autoimmunity.
  5. Active, unresolved infection requiring parenteral antibiotics.
  6. Unresolved abscess at time of treatment (if screening Pelvic MRI identifies an abscess, it must be resolved before treatment).
  7. Target fistula with any of the following characteristics (note that presence of a second fistula tract that is distinctly separate from the target fistula, or a target fistula with a single internal opening and multiple external openings is not exclusionary):

    1. Target fistula has a branching blind ending sinus tract (no external opening) that investigator assesses to be at elevated risk of abscess formation if treated with AVB-114.
    2. Target fistula is a genito-urinary fistula, including rectovaginal (i.e., fistulae that transverse the vaginal canal).
    3. Any anatomical limitation to successfully securing the fistula plug disk.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Available treatment

  • BiologicalAVB-114

    AVB-114 is a mesenchymal cell substrate system comprised of autologous mesenchymal cells incubated with a 3-dimensional bioabsorbable substrate. The drug substance is expanded, pure mesenchymal stem cells (MSC) which are known to modulate local inflammation and orchestrate tissue healing. By incubating cells with a 3-dimensional bioabsorbable substrate designed for anal fistula geometry, cells are locally delivered into the fistula tract to promote healing.
