Overview
Brief Summary
This study is an observational study designed to obtain information on the long-term safety, tolerability, and continued activity of Q-Cells®. The study will follow the participants who previously received Q-Cells® for 10 years.
The goal of this observational study is to learn about the long term effects of Q-Cells® in people with transverse myelitis.
The main objectives the study is to evaluate the safety of patients who have received Q-Cells®.
The secondary goal of the study is to get data about the long-term activity of Q-Cells® over a period of 10 years.
Patients will complete exams, lab tests, imaging, and questionnaires to monitor their safety.

Outcomes
Primary Outcomes
Safety Endpoints: Clinical Laboratory assessments: hematology
Time Frame: through study completion, an average of 10 years
Descriptive statistics for raw values as well as change from baseline (entry into this protocol No. QLTFU-101) by original treatment group will be presented for each visit. The number and percentage of subjects with potentially clinically significant laboratory results will be tabulated by original treatment cohort and overall.
Safety Endpoints: Vital signs: Diastolic Blood Pressure
Time Frame: through study completion, an average of 10 years
Diastolic Blood Pressure: Criteria for Clinically Relevant Vital Signs Abnormalities: \>105 mmHg or an increase from pre-dosing of more than 30 mmHg, or \<50 mmHg or a decrease from pre-dosing of more than 20 mmHg
Number of Adverse Events
Time Frame: through study completion, an average of 10 years
Safety will be assessed by the number of Adverse events.These will be recorded via physical examination findings and will be presented in data listings. Clinically significant changes on physical exam in the areas of: general appearance, head, ears, eyes, nose, throat, neck, chest and lungs, cardiovascular, abdomen, neurological, thyroid, musculoskeletal, lymph nodes, extremities and skin, and operative site will be recorded as Adverse Events.
Safety Endpoints: Vital signs: Pulse
Time Frame: through study completion, an average of 10 years
Pulse: Criteria for Clinically Relevant Vital Signs Abnormalities: \>120 beats per minute or an increase from pre dosing of more than 20 beats per minute, or \<50 beats per minute or a decrease from pre dosing of more than 20 beats per minute
Safety Endpoints: Clinical Laboratory assessments: chemistry
Time Frame: through study completion, an average of 10 years
Descriptive statistics for raw values as well as change from baseline (entry into this protocol No. QLTFU-101) by original treatment group will be presented for each visit. The number and percentage of subjects with potentially clinically significant laboratory results will be tabulated by original treatment cohort and overall.
Safety: Vital signs: Systolic Blood Pressure
Time Frame: through study completion, an average of 10 years
Systolic Blood Pressure: Criteria for Clinically Relevant Vital Signs Abnormalities: \>180 mmHg or an increase from pre-dosing of more than 40 mmHg, or \<90 mmHg or a decrease from pre-dosing of more than 30 mmHg
Safety Endpoints: Vital signs: Temperature
Time Frame: through study completion, an average of 10 years
Temperature: Criteria for Clinically Relevant Vital Signs Abnormalities: \>38.5°C and an increase from pre-dosing of at least 1°C
Safety as measured by change in Electrocardiogram (ECG) measures from baseline at 10 years
Time Frame: through study completion, an average of 10 years (Baseline, 10 years)
Number of participants with abnormal ECG readings will be summarized using descriptive statistics by original treatment cohort and visit. ECG findings that are determined to be potentially clinically significant will be summarized.
