Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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 will be a first in human Phase I, ascending dose, multi-center, randomized patient study evaluating the efficacy, safety, PK of AK1320 MS. The study will enroll up to 4 dose escalating cohorts with each cohort having 2 treatment groups. Cohort 1 and Cohort 2 (AK1320 MS group (n=3-7); Control group (n=0-3)) and Cohort 3 and Cohort 4 (AK1320 MS group (n=6-7); Control group (n=0-3)).

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

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
Incidence of Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events
Time Frame: 24 months
24 months
Summary of Neurological Status
Time Frame: 24 months
Neurological status will be determined preoperatively and postoperatively using a comprehensive neurological status scale. Neurological status is based on four types of measurements: lower extremity motor, dermatomal sensation, reflexes and straight leg raise.
24 months

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
Measure Description
Time Frame
Successful Fusion
Time Frame: 24 months
Fusion will be evaluated through CT scans. Successful fusion will be defined as complete bridging bone between the index level transverse processes with a lack of lucency or lucent lines through the fusion mass.
24 months
Oswestry Low Back Pain Disability Questionnaire (ODI)
Time Frame: 24 months
24 months
36-Item Short Form Survey (SF-36v2®)
Time Frame: 24 months
