3K3A-APC for Treatment of Amyotrophic Lateral Sclerosis (ALS)

September 21, 2023 updated by: Macquarie University, Australia

A Phase 2 Open Label Trial of 3K3A-APC in Amyotrophic Lateral Sclerosis

Phase 2 open label trial to investigate the safety and potentially efficacy of 3K3A-APC in patients with Amyotrophic Lateral Sclerosis (ALS).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This Phase 2 open label trial seeks to investigate whether a novel therapy named 3K3A-APC is safe and potentially effective in patients with Amyotrophic Lateral Sclerosis (ALS). A total of 16 patients with ALS will be enrolled into 2 dose cohorts with five doses of 15mg or 30mg doses given 12 hours apart in each cohort. The primary study outcomes are to ensure the safety and tolerability of 3K3AAPC in ALS patients, and to determine whether 3K3A-APC is able to reduce the pathological changes that might possibly cause ALS.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  1. Patients must have clinically definite ALS (Awaji Criteria)
  2. Male or female age 18 years and less than 75 years at time of ALS study
  3. Symptom onset less than 36 months before screening
  4. Diagnosis of ALS less than 24 months before screening
  5. Clinically definite Upper Motor Neuron signs

Exclusion Criteria:

  1. Current treatment with anticoagulants (e.g., warfarin, novel oral anticoagulants, heparin) that might preclude safe completion of the lumbar puncture
  2. Condition that precludes the safe performance of routine lumbar puncture, such as prohibitive lumbar spinal disease, bleeding diathesis, or clinically significant coagulopathy or thrombocytopenia
  3. Use of investigational drugs or devices within 60 days prior to Baseline (dietary supplements taken outside of a clinical trial are not exclusionary, e.g., coenzyme Q10)
  4. Prolonged prothrombin time or activated partial thromboplastin time >2xULN
  5. Severe hypertension or hypotension
  6. Glomerular filtration rate (GFR) <35 mL/min

  8. Prior exposure to any exogenous form of APC
  9. Inability to lie flat for procedures (MRI, PET, LP)
  10. Pregnant or lactating during the study period

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Had Any Serious Adverse Events or Any Adverse Events With Severity Higher Than "Moderate".
Time Frame: 15 Days
Number of participants who had any serious adverse events or any adverse events with severity higher than "moderate", as determined by the Principal Investigator, using the composite safety assessment including clinical laboratory testing (full blood count, biochemistry, coagulation, iron study, CSF analysis and ECG), physical examination and self-reporting of adverse events. All clinical significant findings in the composite safety assessment were reported as adverse events.
15 Days
Percentage of Change in PERSI Score in the Motor Cortex Before and After Dosing
Time Frame: 7 Days
PERSI (Parametric Estimation of Reference Signal Intensity) score is the measurement of microglial activation in the motor cortex utilising serial [18F]FEMPA PET imaging. The percentage of change in PERSI score before and after dosing in the two (2) dose cohorts is calculated.
7 Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
