About this study
Official title: A Phase 2a, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of the Safety, Tolerability, Pharmacodynamics, and Pharmacokinetics of AP-101 in Participants With Sporadic or SOD1-Associated ALS
The purpose of this study is to evaluate the safety, tolerability, PK, and PD of AP-101 in participants with fALS and sALS.
Read the detailed description
This Phase 2a, multicenter, randomized, double-blind, placebo-controlled study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamic markers of AP-101 in adults with sporadic ALS or SOD1-associated ALS. A total of 73 participants were randomized within each ALS cohort in a 2:1 ratio to receive AP-101 or placebo during a 24-week double-blind treatment period.
Participants assigned to AP-101 received a 500 mg intravenous loading dose on Day 1, a 2500 mg intravenous dose on Day 2, and 2500 mg intravenously every 3 weeks beginning on Day 22 through Week 24. Participants assigned to placebo received matching intravenous infusions on the same schedule. Stable use of locally approved ALS treatments was permitted.
Participants who completed the double-blind period could enter an optional 24-week open-label extension in which all participants received AP-101. To maintain the integrity of the double-blind period, the initial dose in the open-label extension remained blinded. Participants were followed for safety and pharmacokinetic assessments for up to 16 weeks after their final study dose.
The primary assessments evaluated adverse events, serious adverse events, immunogenicity, vital signs, clinical laboratory assessments, physical and neurological examinations, electrocardiograms, and changes in weight. Secondary assessments included serum pharmacokinetics, AP-101 concentrations in cerebrospinal fluid, and the neurofilament biomarkers phosphorylated neurofilament heavy chain (pNfH) and neurofilament light chain (NfL). Exploratory assessments included the ALS Functional Rating Scale-Revised, slow vital capacity, muscle strength, King's staging, survival and ventilation outcomes, quality of life, and cerebrospinal fluid total and misfolded SOD1.

What is being measured
The primary outcome is the main question the study is designed to answer.
Participants With Treatment-Emergent Adverse Events (TEAE) and Treatment-Emergent Serious Adverse Events (TESAE) During the Double-Blind Period
Treatment-emergent adverse events were adverse events that began or worsened after the first dose of randomized study treatment during the double-blind period. Treatment-emergent serious adverse events met the protocol-defined criteria for seriousness. Participants experiencing more than one event within a category were counted once in that category. Results are presented separately for the sporadic ALS and SOD1-associated ALS cohorts.
Measured: From the first dose through the 21-day follow-up after Week 24, approximately 27 weeks
Number of Participants With Abnormalities in Vital Signs, Clinical Laboratory Assessments, Physical and Neurological Examinations, and Electrocardiograms
Number of participants with at least one abnormality in vital signs, clinical laboratory assessments, physical examinations, neurological examinations, or electrocardiograms during the double-blind period. Participants could be included in more than one category; therefore, categories were not mutually exclusive. Results are presented separately for the sporadic ALS and SOD1-associated ALS cohorts.
Measured: From the first dose through the 21-day follow-up after Week 24, approximately 27 weeks
Participants With Treatment-Emergent Anti-Drug Antibodies (ADAs) During the Double-Blind Period
Serum samples were assessed for anti-drug antibodies to AP-101. Participants were evaluable for treatment-emergent anti-drug antibodies if they had at least one non-missing baseline result and at least one non-missing post-baseline result. One participant was anti-drug-antibody positive at baseline and subsequently tested negative; baseline positivity was not classified as treatment-emergent. Results are presented separately for the sporadic ALS and SOD1-associated ALS cohorts. ADA testing was not assessed in placebo participants.
Measured: From baseline through the 21-day follow-up after Week 24, approximately 27 weeks
Secondary outcomes (6)
Model-Derived Elimination Half-Life of AP-101 in Serum
The individual elimination half-life of AP-101 was estimated using empirical Bayes estimates from the final two-compartment population pharmacokinetic model. The model used pooled serum AP-101 concentration data from studies AP101-01 and AP101-02. This outcome summarizes participants from AP101-02 who were included in the final population pharmacokinetic model.
Measured: From the first AP-101 dose through 16 weeks after the final AP-101 dose, up to approximately 64 weeks
Model-Derived Area Under the Serum AP-101 Concentration-Time Curve
Individual AP-101 exposure was estimated using empirical Bayes estimates from the final two-compartment population pharmacokinetic model. Area under the concentration-time curve during the dosing interval was estimated following the second active AP-101 dose and at steady state. This outcome summarizes AP101-02 participants included in the final population pharmacokinetic model.
Measured: AUC following the second active dose: Day 2 through Day 22; AUC at steady state: the 21-day dosing interval following the participant's final active AP-101 dose, which occurred up to approximately Week 48 of the study
Model-Derived Maximum Serum AP-101 Concentration
Individual maximum serum AP-101 concentrations were estimated using empirical Bayes estimates from the final two-compartment population pharmacokinetic model. Maximum concentration was estimated following the second active AP-101 dose and at steady state. This outcome summarizes AP101-02 participants included in the final population pharmacokinetic model.
Measured: Cmax following the second active dose: Day 2 through Day 22; Cmax at steady state: during the 21-day dosing interval following the participant's final active AP-101 dose, which occurred up to approximately Week 48 of the study.
AP-101 Concentration in Cerebrospinal Fluid During the Double-Blind Period
AP-101 concentrations were measured in cerebrospinal fluid to assess central nervous system exposure after repeated intravenous dosing. Samples were collected at Week 12 and Week 24 of the double-blind period and summarized by ALS cohort and visit among participants with quantifiable CSF AP-101 concentrations. Actual concentrations were reported rather than change from baseline because nearly all baseline concentrations were below the limit of quantitation.
Measured: Week 12 and Week 24 of the double-blind period
Change From Baseline in Cerebrospinal Fluid Phosphorylated Neurofilament Heavy Chain (pNfH) During the Double-Blind Period
Phosphorylated neurofilament heavy chain (pNfH) concentrations were measured in cerebrospinal fluid at baseline, Week 12, and Week 24. Results represent the mean change from baseline and are presented separately for the sporadic ALS and SOD1-ALS cohorts. Negative values indicate a decrease from baseline.
Measured: Baseline to Week 24 of the double-blind period
Change From Baseline in Serum Neurofilament Light Chain During the Double-Blind Period and 21-Day Follow-up
Neurofilament light chain (NfL) concentrations were measured in serum at baseline, Week 12, Week 24, and the 21-day follow-up after completion of double-blind treatment. Results represent the mean change from baseline and are presented separately for the sporadic ALS and SOD1-ALS cohorts. Negative values indicate a decrease from baseline.
Measured: Baseline through the 21-day follow-up after Week 24, approximately 27 weeks
