About this trial
The purpose of this study is to investigate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of TCD601 (siplizumab) in newly diagnosed adult ALS patients.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Male or female patients ≥ 18 to 80 years of age.
Diagnosis of ALS by revised El Escorial Criteria, at study entry within 24 months of first symptoms.
Patients on existing ALS treatment must have been on a stable dose for 28 days.
Disqualifiers
Patient with severe systemic infections, current or within the two weeks prior to randomization.
Subjects who, in the opinion of the investigator, are not capable of giving informed consent for the study or who are unable or unwilling to adhere to the study requirements outlined in the protocol.

Trial outcomes
Primary outcomes
Evaluation of the safety of TCD601 in adult patients with ALS
Assess the incidence of treatment-emergent Adverse Events \[Safety and Tolerability\]
Secondary outcomes
Evaluation of the pharmacokinetics (PK)
Siplizumab concentration over time
Correlation of ALS disease status with leucocyte phenotypic profiles
The ALS disease status measured by ALSFRS and Kings staging will be compared with the leucocyte phenotypes measured by FACS analysis.
Evaluation of levels of biomarkers
Neurofilament light chain levels over time
Length of time from trial entry to tracheostomy / death
The time from study enrollment to patient death or tracheostomy will be measured.
