Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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 long-term, 3-year, follow-up study for patients completing the KS-GIG-001-01 Study (A Phase 1/2a, First-in-Human, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Therapeutic Activity of Single Ascending Doses of KLS-2031 Administered by Transforaminal Epidural Injection in Patients with Neuropathic Pain from Lumbosacral Radiculopathy). Following the end of the Open-label Safety Extension Period of the KS-GIG-001-01 Study (Visit 14), patients will enter the Long-term Follow-up Period. These patients will continue to be monitored for AEs (including AEs of special interest) and serious AEs (SAEs) via phone call every 6 months and outpatient visits every 52 weeks (annually), over 3 years.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

This long-term follow-up study will include up to 12 patients with neuropathic pain from LSR that have completed the KS-GIG-001-01 Study and were randomized to receive KLS-2031.

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
Long-term safety of KLS-2031 as assessed by frequency and nature of AEs, laboratory test results, vital sign measurements, physical and complete neurological examinations, and 12 lead ECGs through 156 weeks.
Time Frame: Baseline through the end of study (approximately 3 years)
Long-term safety of KLS-2031 as assessed by frequency and nature of AEs, laboratory test results, vital sign measurements, physical and complete neurological examinations, and 12 lead ECGs through 156 weeks.
Baseline through the end of study (approximately 3 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
Measure Description
Time Frame
Change from baseline to each visit in Pain Intensity Numerical Rating Scale (PI-NRS) score = Result at week n - baseline, (n=52, 104, 156)
Time Frame: Week 52, Week 104, Week 156
The PI-NRS is measured on an 11-point numerical scale ranging from 0 (no pain) to 10 (worst possible pain) that the patient selects to best describe the intensity of pain that they have experienced in the last 24 hours.
Week 52, Week 104, Week 156
Change from baseline to each visit in Daily Sleep Interference Scale (DSIS) score = Result at week n - baseline, (n=52, 104, 156)
Time Frame: Week 52, Week 104, Week 156
The DSIS has an 11-point numerical scale that asks the patient to assess how pain has interfered with their sleep during the past 24 hours. Response options range from 0 (does not interfere with sleep) to 10 (completely interferes with sleep).
Week 52, Week 104, Week 156
Change from baseline to each visit in Galer Neuropathic Pain Scale (Galer NPS) score = Result at week n - baseline, (n=52, 104, 156)
Time Frame: Week 52, Week 104, Week 156
The Galer NPS is a relatively simple, self-administered, 10-item questionnaire for evaluating pain, which assesses distinct pain qualities associated with neuropathic pain.
Week 52, Week 104, Week 156
Change from baseline to each visit in modified Roland-Morris Disability Questionnaire (RMDQ) score = Result at week n - baseline, (n=52, 104, 156)
Time Frame: Week 52, Week 104, Week 156
The modified RMDQ is a self-administered, 24-question physical disability measurement tool that evaluates both back and leg pain. Each of the 24 questions is asked 2 times, once with regard to back pain and once with regard to leg pain, for a total of 48 items. Each question requires a "yes" or "no" answer; 1 point is scored for each positive response. The total scores are determined on a scale of 0 to 24 for back pain and on a scale of 0 to 24 for leg pain, with 0 representing "no disability" and 24 representing "extreme disability."
Week 52, Week 104, Week 156
