Clinical Trial Summary

This is a long-term, 3-year, follow-up study for patients completing the KS-GIG-001-01 Study


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Long-term safety of previous treatment as assessed by frequency and nature of adverse events (AEs) Baseline through end of study (approximately 3 years)
Secondary Change from baseline to each visit in Pain Intensity Numerical Rating Scale (PI-NRS) score = Result at week n - baseline, (n=52, 104, 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
Secondary Change from baseline to each visit in Daily Sleep Interference Scale (DSIS) score = Result at week n - baseline, (n=52, 104, 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
Secondary Change from baseline to each visit in Galer Neuropathic Pain Scale (Galer NPS) score = Result at week n - baseline, (n=52, 104, 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
Secondary Change from baseline to each visit in modified Roland-Morris Disability Questionnaire (RMDQ) score = Result at week n - baseline, (n=52, 104, 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
