Current Active Regimens

Regimen F: Trial of ABBV-CLS-762 (Now Enrolling)
Developed by Calico in collaboration with AbbVie, ABBV-CLS-7262 targets eIF2B, a key regulator of the integrated stress response (ISR), a pathway activated in people with ALS. In neurons exposed to cellular stressors, inhibition of the ISR by ABBV-CLS-7262 restores protein synthesis and dissolves pre-formed TDP-43 containing stress granules. This effect of ABBV-CLS-7262 is of clinical interest because TDP-43 containing stress granules are thought to lead to TDP-43 inclusions, a hallmark of ALS pathology.

Regimen G: Trial of DNL343 (Now Enrolling)
DNL343 is a novel investigational ALS therapy that targets eIF2B, a central regulator of the integrated stress response (ISR). The ISR appears to be overactive in ALS, leading to the formation of stress granules containing TDP-43. Buildup of TDP-43 is harmful and leads to neuronal degeneration. In the lab, inhibition of the ISR by DNL343 dissolves TDP-43 containing stress granules and decreases ISR biomarkers. The safety, pharmacokinetics, and pharmacodynamics of DNL343 have been characterized in both healthy participants and people with ALS, in a Phase 1 (N=47) and a Phase 1b (N=29) study, respectively, with dosing for up to 28 days. Results from both studies demonstrated that once-daily oral dosing with DNL343 was generally well tolerated and exhibited extensive Cerebrospinal Fluid (CSF) penetration. In addition, robust inhibition of biomarkers associated with the ISR pathway was observed in blood samples from study participants.

Trial of Baricitinib for NADALS Phase 1-2

Full Trial Name: Neurodegenerative Alzheimer’s Disease and Amyotrophic Lateral Sclerosis (NADALS) Basket Proof of Concept Trial including Asymptomatic Individuals using Baricitinib

Trial Phase: Phase 1-2

Trial Length: Up to 28 weeks (Up to 7 in-person visits)

Drug to Placebo Ratio: No Placebo

Target: Type I interferon signaling

Science: Baricitinib aims to block type I interferon signaling, which is robustly active within the central nervous system of subsets of patients with Amyotrophic Lateral Sclerosis and Alzheimer’s Disease. Type 1 interferon signaling is an immune response that promotes inflammation which can lead to motor neurons dying and the progression of ALS symptoms. 

Administration: One 2 mg tablet once per day for the first 8 weeks of the trial, two 2 mg tablets once per day for the remaining 16 weeks. Tablets can be taken orally or crushed and administered through a G-tube

Purpose: In this study, the levels of baricitinib present in blood and cerebrospinal fluid (CSF) will be measured to determine safety and its effect on biomarkers related to ALS and AD. We hope these findings will help better evaluate the efficacy of baricitinib for the treatment of ALS.

Trial of BLZ945 for ALS – Phase 2

Full Trial Name: An open-label, adaptive design study in patients with ALS to characterize safety, tolerability and brain microglia response, as measured by TSPO binding, following multiple doses of BLZ945 using positron emission tomography (PET) with radioligand [11C]-PBR28

Trial Phase:

Trial Length: 6 months

Drug to Placebo Ratio: Open label (no placebo)

Target: Inhibitor of CSF-1R

Science: In people with ALS, immune cells in the brain called microglia are activated and cause neuroinflammation. The goal of this study is to reduce neuroinflammation through treatment of BLZ945. This will be evaluated using PBR28 PET imaging to measure microglial activation, as well as through collection of biomarkers of neuroinflammation and disease activity in participants with ALS.

Administration: Oral pill taken once per week or for the first four days of a two-week period

Purpose: To learn about the safety and tolerability of BLZ945 in adults with a diagnosis of Amyotrophic Lateral Sclerosis (ALS) and to help select the most appropriate doses for the planning of future research in patients with ALS.

Trial of ION363 for FUS-ALS – Phase 1-3

Sponsor: Ionis Pharmaceuticals

Full Trial Name: A Phase 1-3 Study to Evaluate the Efficacy, Safety, Pharmacokinetics and Pharmacodynamics of Intrathecally Administered ION363 in Amyotrophic Lateral Sclerosis Patients with Fused in Sarcoma Mutations (FUS-ALS)

Trial Phase: 1-3

Trial Length: Up to 3 years and 11 months (up to 20 in-person visits)

Participants: People with FUS ALS

Drug to Placebo Ratio: 2:1 for 14 months, open label extension (OLE) for 20 months

Target: FUS RNA

Science: ION363 is an investigational antisense medicine targeting the FUS gene to reduce production of the FUS protein. There is evidence that mutations in the FUS gene can lead to rapid, progressive loss of motor neurons in patients with FUS-ALS, so this drug may reduce or prevent disease progression in FUS-ALS patients.

Administration: Lumbar puncture (needle inserted into spinal fluid in the lower spine to administer dose)

Purpose: To evaluate the efficacy of the study drug in functioning and survival in ALS patients with FUS mutations.

Trial of RAPA-501 Cell Therapy for ALS – Phase 2/3

Full Trial Name: Phase 2/3 Trial of Autologous Hybrid TREG/Th2 Cell Therapy (RAPA-501) for Amyotrophic Lateral Sclerosis
Trial Phase: 2/3
Trial Length: Up to 1 year (10-30 in-person visits)
Drug to Placebo Ratio: Open Label (no placebo)
Target: T-cells

Science: In people with ALS, the body’s immune system becomes imbalanced and appears to hasten the loss of motor neurons in the brain and spinal cord. Regulatory T-cells help reduce inflammation and could lead to a more balanced immune system in people with ALS. The goal of this study is to reduce neuroinflammation, potentially slowing ALS progression, using specially prepared regulatory T-cells, called RAPA-501 cells. RAPA-501 cells are created through a series of steps by first taking the participant’s own blood though a specialized IV (apheresis), then isolating regulatory T-cells from the blood. Next, these regulatory T-cells are grown under special conditions in a petri dish, becoming RAPA-501 cells. The RAPA-501 cells are then returned to the participant through an intravenous infusion. Prior to the IV infusion of RAPA-501 cells, a low dose of chemotherapy is given to reduce the body’s immune response and potentially heighten the effects of the RAPA-501 cells.


(1) Apheresis (blood separation) to collect T-cells

(2) Intravenous (IV) infusion of low-dose chemotherapy drugs (Cyclophosphamide and Pentostatin)

(3) Intravenous (IV) infusion of the specialized RAPA-501 cells

Purpose: The purpose of this study is to find out if RAPA-501 cell therapy is safe in people living with ALS. Two doses of RAPA-501 cells will be investigated for safety.

Trial of LAM-002A for C9orf72-Associated ALS – Phase 2a

Full Trial Name: A Phase 2a Trial to Evaluate the Safety, Tolerability, and Biological Activity of LAM-002A (apilimod dimesylate capsules) in C9ORF72-Associated ALS

Trial Phase: 2a

The aim of this Phase 2 research study is to find out if LAM-002A is a safe treatment option for patients with C9ORF72-associated ALS (C9ALS). During the study, participants will receive the LAM-002A drug orally in pill form. This is an open label extension trial, meaning that for the first 12 weeks, some participants will receive a placebo (which looks like the study drug, but has no active ingredients) instead of LAM-002A. Following the completion of weeks 1-12, all participants will be eligible to receive LAM-002A for the next 12 weeks of the trial. Participation in this study will involve blood draws, lumbar punctures, and several clinical measures of ALS, as research staff seek to understand how LAM-002A is processed by the body and if it impacts ALS progression. Our team is looking for patients with C9ALS and a slow vital capacity of ≥50% who are willing to complete 10 study visits and several phone calls over 28 weeks.
