Clinical Trial Summary

This is a Randomized, Double-Blind, Placebo-Controlled Study designed to assess safety, tolerability, and efficacy of NM8074 in AAV patients when used in combination with Standard of Care (SOC) cyclophosphamide/azathioprine or rituximab plus corticosteroids.

Description:

The proposed study, NM8074-AAV-501, will initially assign six (6) patients per cohort in a 2-cohort trial. In the first cohort, we will evaluate a biweekly dosing regimen with NM8074 and SOC whereas in the second cohort, we will evaluate placebo with SOC. These studies will assess safety, tolerability, and efficacy of NM8074 in AAV patients when used in combination with SOC cyclophosphamide/azathioprine or rituximab plus corticosteroids.

Secondary	Change from Baseline or Percent Change from Baseline in quality of life (QoL) Assessed via the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale, Version 4.	The FACIT-fatigue scale is a 13-item patient-reported measure of fatigue with a 7-day recall period. Items are scored on a 0 - 4 response scale ranging from "Not at all" to "Very much so". All items are summed to create a single fatigue score with a range from 0 to 52 with a better quality of life indicated by a higher score.	Up to Study Day 133
Secondary	Change from Baseline or Percent Change from Baseline in Quality of Life (QoL) Assessed via the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 Scale (QLQ- C30), Version 3.0	All EORTC QLQ-C30 scales and single-item measures range from 0 to 100. This includes 3 symptom scales (fatigue, pain, nausea and vomiting), 5 functional scales (physical, role, cognitive, emotional, and social), single-item questions addressing symptoms like insomnia, dyspnea, loss of appetite, and others that are commonly reported by cancer patients, and the perceived financial impact of the disease. A higher score is associated with a greater quality of life for global health status.	Up to Study Day 133
Secondary	Change from Baseline or Percent Change from Baseline in Quality of Life (QoL) assessed via EQ-5D-5L	The EuroQol 5 Dimension 5 Level (EQ-5D-5L) is a self-assessed, health related QoL which measures QoL in a 5-component scale including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The digits for 5 dimensions can be combined in a 5-digit number describing the respondent's health state.	Up to Study Day 133
Secondary	Change from Baseline or Percent Change from Baseline in Quality of Life (QoL) assessed via SF-36v2	The Short Form Health Survey version-2.0 (SF-36v2) questionnaire is a short-form health survey that measures each of the following eight health domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Scales are standardized with a scoring algorithm from 0 to 100.	Up to Study Day 133
