NCT06704347

Brief Summary

This is a Phase 1, open-label, multi-center safety study of XT-150 in adult participants with Amyotrophic Lateral Sclerosis (ALS). Participants providing informed consent and meeting all study eligibility criteria will be enrolled in the study and will receive a single injection of XT-150 at the Baseline visit. Follow-up visits will occur over 180 days (6 months) after the injection. 8 participants (4 participants per dose level) will be enrolled sequentially in up to 2 ascending, single dose cohorts: Cohort 1: 1.5 mg XT-150 Cohort 2: 4.5 mg XT-150

Outcome Measures

Primary Outcomes (4)

  • Number of participants reporting adverse events (AEs), Serious Adverse Events (SAEs) and AEs of Special Interest (AESIs)

    Up to Day 180

  • Number of participants with clinically significant physical examination findings

    Up to Day 180

  • Number of participants with clinically significant vital sign abnormalities

    Vital signs include temperature, heart rate, respiratory rate and blood pressure

    Up to Day 180

  • Number of participants with clinically significant laboratory abnormalities

    Clinical laboratory assessments include hematology, chemistry, coagulation, lipids, C-reactive protein, erythrocyte sedimentation rate and CSF total protein, cell count and glucose

    Up to Day 180

Study Arms (2)

Cohort 1: 1.5 mg XT-150

EXPERIMENTAL

Participants will be administered 1.5 mg of XT-150 once by intrathecal injection on Day 1. An intrathecal injection is an injection using a thin needle inserted into the spinal canal at the base of your spinal cord performed by your study doctor.

Biological: XT-150

Cohort 2: 4.5 mg XT-150

EXPERIMENTAL

Participants will be administered 1.5 mg of XT-150 once by intrathecal injection on Day 1. An intrathecal injection is an injection using a thin needle inserted into the spinal canal at the base of your spinal cord performed by your study doctor.

Biological: XT-150

Interventions

XT-150BIOLOGICAL

XT-150 is a small piece of plasmid DNA (genetic material) that produces a variant of the anti-inflammatory cytokine, Interleukin 10 (IL-10).

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults between 18 and 80 years of age
  • Male or female, if of childbearing potential or sexually active, strict contraception required
  • Have ALS diagnosed by a doctor (specifically, sporadic or familial ALS diagnosed as clinically probable, lab-supported probable or definite ALS defined by the El Escorial criteria)
  • Have had symptoms of ALS (muscle weakness) within 36 months of starting this study
  • Have the ability to slowly exhale a volume of air at least 60% of what is expected for the participant's sex, height and age
  • Have not received treatment for ALS or are currently on a stable dose of an approved treatment for ALS. Patients currently receiving Tofersen are not eligible.
  • Able to receive the study injection intrathecally, determined by the study doctor
  • Able to undergo the study procedures and adhere to the study visit schedule at the time of study entry, with an estimated life expectancy of 6 months or greater

You may not qualify if:

  • Have an implanted shunt to drain cerebrospinal fluid (CSF) or an implanted CNS catheter
  • Have an implanted of diaphragm pacing system
  • Tracheostomy
  • History or current diagnosis of cardiac conditions or ECG abnormalities indicating significant risk of safety for participants in the study
  • History or current diagnosis of respiratory conditions such as COPD
  • History or current diagnosis of cancer, chemical meningitis, HIV, Hep B, Hep C, uncontrolled diabetes
  • Presence of an autoimmune condition (for example, rheumatoid arthritis or lupus) requiring treatment or immunodeficiency
  • Clinical or laboratory evidence of hepatic or renal disease/injury.
  • Taking any prohibited medications
  • Women who are pregnant or nursing
  • Use of any investigational drugs or devices within 30 days or 5 half-lives of the study agent (whichever is longer). Exception: Observational, non-interventional clinical studies are allowed in the opinion of the study doctor.
  • Any other condition that the study doctor feels could compromise the participant's safety, ability to communicate with the study staff, or the quality of the data
