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 is an open-label single dose, parallel group, 24-week, Phase 1 study in 16 healthy participants.

The study is designed to evaluate and compare the safety, tolerability, PK, and immunogenicity of AIO-001 using two different formulations (Formulation A and Formulation B) in 16 healthy volunteers (8 receiving each formulation).

The study will include a screening visit from Day -28 to Day -2. Eligible participants will be admitted to the clinical site on Day -1 and will be confined until completion of the assessments on Day 3. Participants will return to the clinical site for outpatient visits for study assessments and laboratory tests.

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 With Treatment-emergent Adverse Events (TEAEs)
Time Frame: From Day 1 up to Day 169
An AE was defined as any untoward medical occurrence in a participant or clinical trial participant administered a pharmaceutical product and which did not necessarily have a causal relationship with the treatment. An AE can, therefore, be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product. TEAEs were defined as AEs that commence on or after the time of study drug administration.
From Day 1 up to Day 169
Number of Participants With Clinically Significant Changes in Vital Signs
Time Frame: Baseline (Day -1) up to Day 169
Vital sign measurements included blood pressure, heart rate, respiratory rate, and oral temperature measurements. The clinically significant changes were based on investigator's judgement.
Baseline (Day -1) up to Day 169
Number of Participants With Clinically Significant Changes in 12-lead Electrocardiogram Parameters
Time Frame: Baseline (Day -1) up to Day 169
The electrocardiogram parameters included heart rate, PR interval, QT interval, corrected QT (QTcF using Fridericia's formula) interval and QRS. The clinically significant changes were based on investigator's judgement.
Baseline (Day -1) up to Day 169
Number of Participants With Clinically Significant Changes in Physical Examination Findings
Time Frame: Baseline (Day -1) up to Day 169
Physical examination included assessments of the following: head, eyes, ears, nose, throat, neck, chest, lungs, abdomen, musculoskeletal, dermatological, cardiovascular/peripheral vascular, and general neurological examination. The clinically significant changes were based on investigator's judgement.
Baseline (Day -1) up to Day 169
Number of Participants With Clinically Significant Changes in Clinical Laboratory Parameters
Time Frame: Baseline (Day -1) up to Day 169
Clinical laboratory parameters included biochemistry, hematology, and urinalysis assessment. The clinically significant changes were based on investigator's judgement.
Baseline (Day -1) up to Day 169

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
Time Frame
Area Under the Concentration-time Curve From Time Zero Until the Last Observed Concentration (AUC0-last) of AIO-001
Time Frame: Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Blood samples were collected at indicated time points for pharmacokinetic (PK) analysis of AIO-001. PK analysis was conducted using standard non-compartmental methods.
Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Area Under the Concentration-time Curve From Time Zero to Infinity (AUC0-inf) of AIO-001
Time Frame: Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Blood samples were collected at indicated time points for PK analysis of AIO-001. PK analysis was conducted using standard non-compartmental methods. The residual area was greater than 20% in 15 out of the total of 16 participants and therefore the estimation of AUC0-inf may be non-identifiable.
Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Maximal Observed Concentration (Cmax) of AIO-001
Time Frame: Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Blood samples were collected at indicated time points for PK analysis of AIO-001. PK analysis was conducted using standard non-compartmental methods.
Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Time to Maximal Observed Concentration (Tmax) of AIO-001
Time Frame: Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Blood samples were collected at indicated time points for PK analysis of AIO-001. PK analysis was conducted using standard non-compartmental methods.
Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Terminal Elimination Half-life (T½) of AIO-001
Time Frame: Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Blood samples were collected at indicated time points for PK analysis of AIO-001. PK analysis was conducted using standard non-compartmental methods. The residual area was greater than 20% in 15 out of the total of 16 participants and therefore the estimation of T½ may be non-identifiable.
Pre-dose, 12, 24, 48, 72, 96, 120, 168, 240, 336, 504, 672, 1008, 1344, 1680, 2016, 2688, 3360, and 4056 hours post-dose
Number of Participants With Positive Anti-drug Antibody (ADA) to AIO-001
Time Frame: Up to Day 169
ADA-positive participant was defined as participant with at least one treatment-induced or treatment-boosted ADA-positive sample at any time during the treatment or follow-up observation period. Anti-AIO-001 antibodies were evaluated in serum samples. Serum samples were screened for antibodies binding to AIO-001.
Up to Day 169
