A Trial of Tocilizumab in ALS Subjects

Completed · Phase 2 · Has a placebo group

Conditions studied: ALS, Amyotrophic Lateral Sclerosis, Lou Gehrig's Disease, Motor Neuron Disease

In brief

This research study is being done to find out if tocilizumab, also known as Actemra™, can help with Amyotrophic Lateral Sclerosis (ALS). The investigators also want to find out if tocilizumab is safe to take without causing too many side effects. Currently ALS has no cure and 2 modestly effective treatment to slow the progression of the disease. Although not the initial cause of ALS, the immune system plays a role in the death of motor neurons. The immune cells that participate in this process are stimulated by a substance called interleukin-6 (IL-6) whose effect is blocked by tocilizumab and thus, may slow the death of motor neurons and slow the disease.

• Capable of providing informed consent and complying with trial procedures.
• High inflammatory profile of PBMC gene expression
• Upright SVC ≥40% of predicted value for gender, height and age at Screening and in the opinion of the investigator is able to comply with and complete the trial.
• Women must not be able to become pregnant for the duration of the study.
• Negative tuberculosis blood or skin test at Screening
• Not taking riluzole, or on a stable dosage for at least 30 days prior to Screening.
• Subjects medically able to undergo lumbar puncture (LP)
• Subjects must agree not to take live attenuated vaccines 30 days before Screening, throughout the duration of the trial and for 60 days following the subject's last dose of study drug
• Geographic accessibility to the study site
• Additional MRI-PET Inclusion Criteria (MGH only):
• High or mixed affinity to bind TSPO protein (Ala/Ala or Ala/Thr) (see section 7.1)

• History of severe allergic or anaphylactic reactions to human, humanized or murine monoclonal antibodies
• Presence of any of the following clinical conditions: bleeding diathesis, or any other clinical condition that would, in the opinion of the investigator, place the patient at increased risk during LP.
