What is being measured

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

  1. Body Weight-Adjusted Serum Clearance (CL) of Sotrovimab

    Blood samples were collected at indicated timepoints and Pharmacokinetic (PK) analysis was performed. PK parameters were determined by population PK modelling method. The model considered the body weight of each participant to calculate the serum clearance of sotrovimab.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  2. Maximum Observed Concentration (Cmax) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and PK analysis was performed. PK parameters were determined by non-compartmental methods using Phoenix WinNonlin. The log-transformed data is transformed back to the original scale and presented here.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  3. Time to Reach Cmax (Tmax) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and PK analysis was performed. PK parameters were determined by non-compartmental methods with Phoenix WinNonlin.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  4. Area Under the Serum Concentration-Time Curve From Time Zero to Infinity (AUC[0-inf]) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and Pharmacokinetic (PK) analysis was performed. PK parameters were determined by population PK modelling method.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  5. Terminal Elimination Half-Life (T1/2) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and Pharmacokinetic (PK) analysis was performed. PK parameters were determined by population PK modelling method.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  6. Apparent Volume of Distribution During Terminal Phase (Vz) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and PK analysis was performed. PK parameters were determined by non-compartmental methods with Phoenix WinNonlin. The log-transformed data is transformed back to the original scale and presented here.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  7. Clearance (CL) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and PK analysis was performed. PK parameters were determined by non-compartmental methods with Phoenix WinNonlin. The log-transformed data is transformed back to the original scale and presented here.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  8. Relative Bioavailability (F) Following Administration of Sotrovimab

    Blood samples were collected at indicated timepoints and PK analysis was performed. PK parameters were determined by non-compartmental methods with Phoenix WinNonlin.

    Measured: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12

  9. Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), and AEs of Special Interest (AESI)

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. A SAE is any untoward medical occurrence that, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity and/or can result in death. Protocol defined AESIs were included.

    Measured: Up to Day 29

  10. Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), and AEs of Special Interest (AESI) Up to Week 36

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. A SAE is any untoward medical occurrence that, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity and/or can result in death. Protocol defined AESIs were included.

    Measured: Up to Week 36

Secondary outcomes (3)
  1. Number of Participants With Progression of COVID-19 Through Day 29

    Progression of COVID-19 is defined as need for attended medical visit (including the visit to a hospital emergency room for management of illness or hospitalization for acute management of illness) or escalation to higher level of medical care or death.

    Measured: Up to Day 29

  2. Number of Participants With Development of Severe and/or Critical Respiratory COVID-19 Through Day 29

    Severe and/or critical respiratory COVID-19 as manifested by requirement for supplemental oxygen through Day 29. For participants who required oxygen or respiratory support for premorbid conditions, disease progression was defined as any sustained (greater than [>]24 hours) increase in the level or method of oxygen support required.

    Measured: Up to Day 29

  3. Change From Baseline in Viral Load in Nasal Secretions Measured by Quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR)

    The viral load change from baseline in nasal secretions was measured by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) at Day 5, Day 8, and Day 11.

    Measured: Baseline (Day 1), at Day 5, Day 8 and Day 11

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sotrovimab in people with COVID-19, run by GlaxoSmithKline at 2 sites in United States.

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 3 inclusion and 11 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: stopped early, as of the sponsor's last update on 3 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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. 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 3 Jan 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?

Body Weight-Adjusted Serum Clearance (CL) of Sotrovimab (time frame: Day 1 (End of Infusion), Day 5, 8 and 12, Week 12). The study lists 10 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 3 Jan 2024.
