About this study

Official title: A Phase 1, Randomized, Double-blind, Placebo-controlled Single and Multiple Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetics (PK), and Pharmacodynamics (PD) of Subcutaneous ANX009 in Normal Healthy Volunteers (NHV)

The purpose of this study is to evaluate the safety, tolerability, pharmakokinetics and pharmacodynamics of single and repeated doses of ANX009

Read the detailed description

In this first in human, phase 1, randomized, double-blind, placebo-controlled study, single and multiple ascending doses of ANX009 or placebo will be administered to 48 healthy subjects.

Single Ascending Dose (SAD): Each SAD subject will participate for approximately 4 weeks (3 nights in-clinic confinement).

Multiple Ascending Dose: Each MAD subject will participate for approximately 6 weeks (17 nights in-clinic confinement).

All subjects will be contacted (in clinic visit or phone call) 6 months after study completion.

Being tested
ANX009, Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety: Number of Participants Who Experienced Treatment-Emergent Adverse Events

    Incidence and severity of treatment-emergent adverse events (AEs). AEs will be coded using MedDRA and severity of AEs will be graded using National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE).

    Measured: [Time Frame: Up to Day 29 for SAD; up to Day 43 for MAD]

Secondary outcomes (6)
  1. Pharmacodynamics: Total Amount of Complement Protein in Blood (CH50)

    Serum samples will be obtained to determine the amount of CH50. CH50 will be measured at a local laboratory. CH50 will be measured at a local laboratory.

    Measured: Up to Week 6

  2. Pharmacodynamics: Amount of C1 in Blood (C1q)

    Serum samples will be obtained to determine the amount of C1q. C1q will be measured using a validated enzyme-linked immunosorbent assay (ELISA) method.

    Measured: Up to Week 6

  3. Pharmacokinetic: Maximum Observed Serum Concentration (Cmax) of ANX009

    Single-dose Cmax (Day 1 in SAD and MAD) and multiple-dose Cmax (Day 14 in MAD) will be determined. Blood samples will be obtained, and serum concentrations determined using a validated ELISA method.

    Measured: Pre-dose, immediately after dose, and 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 1 (SAD and MAD) and 36, 48, and 72 hours post-dose Day 1 (SAD)

  4. Pharmacokinetic: Time to Maximum Observed Serum Concentration (Tmax) of ANX009

    Tmax will be determined on Day 1 in SAD and MAD and on Day 14 in MAD. Blood samples will be obtained, and serum concentrations determined using a validated enzyme-linked immunosorbent assay (ELISA) method.

    Measured: Pre-dose, immediately after dose, and 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 1 (SAD and MAD) and 36, 48, and 72 hours post-dose Day 1 (SAD)

  5. Pharmacokinetic: Area Under the ANX009 Serum Concentration-Time Curve to Last Sample (AUC 0-t) and extrapolated through infinity (AUC 0-inf)

    AUC 0-t will be determined on Day 1 in SAD and on Day 14 in MAD. Blood samples will be obtained, and serum concentrations determined using a validated enzyme-linked immunosorbent assay (ELISA) method.

    Measured: Pre-dose, immediately after dose, and 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 1 (SAD and MAD) and 36, 48, and 72 hours post-dose Day 1 (SAD)

  6. Pharmacokinetic: Terminal Half-Life (t1/2) of ANX009

    Half-life will be determined on Day 1 in SAD and on Day 1 and Day 14 in MAD. Blood samples will be obtained, and serum concentrations determined using a validated enzyme-linked immunosorbent assay (ELISA) method

    Measured: Pre-dose, immediately after dose, and 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 1 (SAD and MAD) and 36, 48, and 72 hours post-dose Day 1 (SAD)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ANX009 in people with Safety and Tolerability in Healthy Volunteers, run by Annexon, Inc. at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety: Number of Participants Who Experienced Treatment-Emergent Adverse Events (time frame: [Time Frame: Up to Day 29 for SAD; up to Day 43 for MAD]). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Aug 2021.
