Safety and Preliminary Efficacy Study of NeoFuse in Subjects Undergoing Multi-Level Anterior Cervical Discectomy

August 14, 2019 updated by: Mesoblast, Ltd.

Phase 2 Study Evaluating Safety and Preliminary Efficacy of NeoFuse When Combined With MasterGraft Matrix in Subjects Undergoing Multi-Level Anterior Cervical Discectomy and Fusion With Anterior Cervical Plate Fixation

The purpose of this study is to evaluate the safety and preliminary efficacy of NeoFuse in subjects with a diagnosis of degenerative disc disease (DDD) at 2 or more adjacent cervical vertebral levels between C3-C4 to C7-T1. All subjects in this study will undergo 2 or 3 level anterior cervical discectomy and fusion with anterior cervical plate fixation.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, multicenter, randomized, single-blinded, controlled study evaluating safety and preliminary efficacy of immunoselected, culture-expanded, nucleated, allogeneic MPCs (NeoFuse) combined with MasterGraft Matrix in a commercially available PEEK cervical spacer compared to a cervical Allograft Spacer control in subjects undergoing 2 or 3 level anterior cervical discectomy and fusion with anterior cervical plate fixation.

After the screening and surgical visits, each subject will be evaluated clinically and radiographically within 3 days and 30 days after surgery, and at 3, 6, 12, and 24 months after surgery.

Subjects will be evaluated at the same time points for safety.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Time Frame
To determine the safety of NeoFuse using physical examinations, vital signs, treatment emergent adverse events (TEAEs), and the results of clinical lab tests (hematology, serum chemistry, inflammation, and and immunology).
Time Frame: 2 years
2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To evaluate the fusion success with NeoFuse compared to allograft spacer using CT scans and x-ray of the involved cervical spine levels and assess the change in outcomes (NDI, SF-36, Zung Depression Questionnaire, and WPAI.
Time Frame: 1 years
