Detailed Description

The proposed clinical trial is a phase I/II open-label study to assess the safety and efficacy of a novel tissue engineered airway product, consisting of expanded autologous Bone Marrow (BM) derived Mesenchymal Stromal Cells (MSC) seeded on to a decellularised allogeneic patch of an airway scaffold in subjects with clinically significant bronchopleural fistula. It is a phase I/II open-label study, which is an uncontrolled pilot in 5 subjects.

Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Subjects with known presence of Human Immunodeficiency Virus (HIV) antibody, Hepatitis B surface antigen (HBsAg) or Hepatitis C antibody.
  • Subject who, in the investigator's judgement, is unlikely to complete all protocol required study visits or procedures, including follow-up visits, or comply with the study requirements for participation
  • Subjects with any medical condition, that in the investigator's judgement, is likely to interfere with assessment of safety or efficacy of study treatment.
  • Subject who is pregnant.
  • Subjects with cancer (except for controlled or controllable basal cell carcinoma).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: 3 months (90 days)
Safety: Emergent or worsening Serious Adverse Events (SAEs) related to the BPF implant during the 3 months post-defect repair.

3 months (90 days)

Secondary Outcome Measures
