What is being measured

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

  1. Observed Maximum Concentration (Cmax)

    Cmax is a pharmacokinetic parameter defined as the observed maximum concentration of the study drug in the serum and/or blood. Cmax will be estimated from the sotatercept concentration versus time data using noncompartmental method.

    Measured: From first dose up to Day 28

  2. Time to Maximum Concentration (Tmax)

    Time to observed maximum concentration (Tmax) is defined as the amount of time in days for a drug to reach the maximum concentration after administration.

    Measured: From first dose up to Day 28

  3. Area Under Curve (AUC)-28 Days

    AUC-28 days is defined as area under the concentration-time curve over the first 28-day dosing interval

    Measured: From first dose up to Day 28

  4. AUCinf: Area Under the Concentration-time Curve From Time Zero Extrapolated to Infinity

    Area under the concentration-time curve from time zero extrapolated to infinity. Only Part 1 pharmacokinetic evaluable participants were pre-specified to be evaluated in this endpoint.

    Measured: From first dose up to Day 28

  5. Apparent Total Clearance (CL/F)

    Apparent Total Clearance (CL/F) is defined as the volume of plasma from which the study drug is completely removed per unit of time. It is equal to the drug dose divided by the area-under-the-curve.

    Measured: From first dose up to Day 28

  6. Apparent Volume of Distribution Based on Terminal Phase (Vz/F)

    Apparent volume of distribution based on terminal phase (Vz/F) is defined as the apparent volume in which the current amount of drug in the body must be dispersed in order to give the current plasma concentration. Apparent volume of distribution is important for determining the dose required to produce a desired plasma concentration of the drug.

    Measured: From first dose up to Day 28

  7. Terminal Half-Life (t1/2,z)

    Terminal plasma half-life (t1/2,z) is the time taken for concentration of the study drug to decrease from its maximum concentration (Cmax) to half of Cmax in the blood plasma.

    Measured: Days 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 15, 22, 29, 43, 57, 85 and 113

  9. Length of Time to Rescue Therapy

    The length of time in days that participants who were rescued received treatment. When applicable, participants were rescued for anemia. During the rescue, participants discontinued sotatercept and were unblinded to the study treatment. Participants who were rescued continued in the treatment phase of 200 days and a follow-up phase of 112 days after the treatment phase. Rescue is defined as the need for a blood transfusion or Erythropoiesis-stimulating agent (ESA) therapy.

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 5 inclusion and 12 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 1 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Mar 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Observed Maximum Concentration (Cmax) (time frame: From first dose up to Day 28). The study lists 7 primary outcomes in all. 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 1 Mar 2024.
