- Brief Summary
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, of which motor-neuron's degeneration may be associated with neuroinflammation. Tofacitinib is a Janus kinase (JAK) inhibitor that affects cellular hematopoiesis and cellular immune function. At the same time, tofacitinib is suitable for rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. This study is a single center, single arm, proof of concept, clinical trial study, and it is planned to use tofacitinib to carry out a clinical trial to observe the treatment effect of ALS patients.
- Detailed Description
Amyotrophic lateral sclerosis is a fatal neurodegenerative disease characterized by progressive loss and dysfunction of upper and lower motor neurons located in the brain and spinal cord, further resulting in paralysis. In the occurrence and development of ALS, the degeneration of motor neurons may be related to neuroinflammatory response, often accompanied by excessive proliferation of microglia, astrocyte and oligodendrocyte. Tofacitinib is a Janus kinase (JAK) inhibitor. JAKs are intracellular enzymes that transport signals generated by cytokine or growth factor-receptor interactions on cell membranes, thereby influencing cellular hematopoietic processes and cellular immune function. At the same time, tofacitinib is a marketed drug suitable for rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. In this study, tofacitinib was selected to carry out a clinical randomized controlled trial to observe the treatment effect in ALS patients.
This study is a single center, single arm, proof of concept, clinical trial study. In this study, 12 patients will be enrolled. The treatment will be 1 tablet (5 mg) twice a day, and be administered continuously for a total of 180 days.
Follow up: Face to face interviews will be made on baseline, 30±3 days, 90±7 days, and 180±14 days.
The primary outcome measure was the difference of changes in ALSFRS-R scale scores at 30±3 days, 90±7 days, and 180±14 days from baseline.
Secondary outcomes included the incidence of invasive mechanical ventilation within 180 days , the changes in modified Norris scale scores, quality of life (ALSAQ-40, EQ-5D-5L), lung function, and electromyography indicators at 30±3 days, 90±7 days, and 180±14 days from baseline.
Exploratory outcomes included the changes in muscle strength, gait function, 7T-MRI imaging indicators, biomarkers in plasma and CSF, fatigue level, anxious level and depressive level, constipation clinical score, overactive bladder symptom score and CNS-BFS score at 30±3 days, 90±7 days, and 180±14 days from baseline; clinical progression within 180 days; the relationship between embryological etiology of ALS patients and the severity and progression in ALS patients, as well as the multiple group changes in ALS patients during disease progression.
Safe outcomes included the incidence in adverse event/severe adverse event, death, serious infection, malignant tumor, lymphoproliferative disease, major cardiovascular adverse events, thrombogenesis, abnormal lymphocytes and neutrophilic granuloaytopenia within 180 days.

- 18 years old≤ age≤ 75 years old, males or females;
- Forced vital capacity ≥ 60% of predicted vital capacity during the screening period;
- The diagnosis conforms to the diagnostic criteria for amyotrophic lateral sclerosis on the Gold Coast;
- Based on the analysis of whether the subject significantly deviates from the baseline healthy elderly population, whole exome sequencing (WES) revealed that the embryonic lineage etiology was interpreted as CD8+ T lymphocyte group and Th1 highly activated, and patients with pathways related to neural repair and energy metabolism pathways that were not significantly inhibited;(1.Obtain genomic data of patient embryonic samples (blood or oral swab) through whole exome sequencing (WES) technology;2.Utilizing the Damage Assessment of Genome shotgun (DAGG) system developed by the Turing Darwin Laboratory team, rare coding mutations in patient genomic data are converted into an activity profile of signaling pathways (APSP). If the patient's embryonic genomic interpretation of APSP compared to the baseline healthy population's embryonic APSP shows high activation of CD8+ T lymphocyte group and Th1 activity, and non-significant inhibition of Treg, neural repair, and energy metabolism pathways, the patient may be included in the clinical trial;3.This step is analyzed by the Turing Darwin Laboratory team, and based on the entry criteria of the clinical trial (high activation of CD8+ T lymphocyte group and Th1 activity, and non-significant inhibition of Treg, neural repair, and energy metabolism pathways), a modeling setting for the APSP score threshold for ALS will be established. Patients above the threshold can be included in the trial.

Group Intervention Description Tofacitinib Tofacitinib tablets This group will receive tofacitinib citrate sustained-release tablets at 180 consecutive days .
- Primary Outcome Measures
Name Time Method Changes of ALSFRS-R scale scores in ALS patients day 180±14 Amyotrophiclateral sclerosis functional rating scale revised(ALSFRS-R) is the most common evaluation indicator in ALS related research, with scores ranging from 0 to 48. The higher the score, the better the functional retention and the milder the symptoms.
- Secondary Outcome Measures
Name Time Method Changes of ALSAQ-40 scale scores in ALS patients baseline, day 30±3, day 90±7, and day180±14 The changes of ALSAQ-40 scale scores in ALS patients from baseline. The scale is an evaluation of the quality of life of ALS patients, with indicators including physical activity, dietary ability, social interaction ability, and emotional response. Simple and highly operable, it can be used for patients to self evaluate their quality of life, with scores ranging from 0 to 200. The higher the score, the milder the symptoms.
Changes in EQ-5D-5L scale scores in ALS patients baseline, day 30±3, day 90±7, and day180±14 The changes of EQ-5D-5L scale scores in ALS patients from baseline. It includes five dimensions(mobility, self-care, usual activities, pain/discomfort, anxiety/depression), and each dimension contains five levels of severity - no problem, minor problem, moderate problem, serious problem, extremely serious problem.
Incidence of invasive mechanical ventilation in ALS patients 180 days The incidence of invasive mechanical ventilation in ALS patients.
Changes of modified Norris scale scores in ALS patients day 30±3, 90±7, and 180±14 The changes of modified Norris scale scores in ALS patients from baseline. The modified Norris scale is a self-assessment scale for ALS patients, with scores ranging from 0 to 120, with higher scores indicating better functional retention.
Changes of lung function in ALS patients baseline, day 30±3, day 90±7, and day180±14 The changes of lung function (forced vital capacity) in ALS patients from baseline. Value decline indicates worse outcome of ALS patients, or disease progression and disability.
Changes of electromyography indicators in ALS patients baseline, day 30±3, day 90±7, and day180±14 The changes of electromyography indicators in ALS patients from baseline. Muscle involvement will be assessed by needle electromyography, which analyzes muscle damage qualitatively based on spontaneous, motor unit action potential and recruitment. More muscle involvement indicates worse outcome of ALS patients, or disease progression and disability. The electromyographic indicators include the amplitude of CMAP, munix, and musix of different muscles.
