Study Endpoints

Primary Endpoints

Time-Weighted Average Change in Viral Load From Day 1/Baseline Through Day 7 in Participants in the Full Analysis Set
Up to 7 days
Time-Weighted Average Change in Viral Load From Day 1/Baseline Through Day 7 in a Subset of Participants in the Full Analysis Set Whose Duration of RSV Symptoms Prior to the First Dose of Study Drug is ≤ Median
Up to 7 days
Time-weighted Average Change in Nasal Respiratory Syncytial Viral (RSV) Load From Baseline to Day 9
Baseline to Day 9

The time-weighted average change, often referred to as the DAVG, provides the average viral burden change from baseline. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factors.

Time-Weighted Average Change in Nasal Respiratory Syncytial Virus (RSV ) Viral Load From Baseline (Day 1) to Day 9
Baseline; Day 9

The time-weighted average change, often referred to as the DAVG, provides the average viral burden change from baseline. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.

Percentage of Participants Who Developed a Lower Respiratory Tract Complication
Up to Day 28

A Lower Respiratory Tract Complication (LRTC) was defined as one of the below as determined by the adjudication committee: * Primary RSV lower respiratory tract infection (LRTI) * Secondary bacterial LRTI * LRTI due to unusual pathogens * Lower respiratory tract complication of unknown etiology

Time-Weighted Average Change in Respiratory Syncytial Viral (RSV) Load From Baseline to Day 5
Baseline to Day 5

The time-weighted average change, often referred to as the DAVG, provides the average viral burden change from baseline. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.

Frequently asked questions about Presatovir

What is Presatovir used for?

Presatovir is an investigational small molecule being developed for the treatment of Respiratory Syncytial Virus (RSV) infection. It has been studied in hospitalized adults and in hematopoietic cell transplant and lung transplant recipients with RSV infection of the upper or lower respiratory tract.

Who makes Presatovir?

Presatovir is being developed by Gilead Sciences, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol GILD. The company has sponsored Phase 2 clinical trials evaluating the drug in patients with Respiratory Syncytial Virus infection.

What phase is Presatovir in?

Presatovir is in Phase 2 clinical development. It is an investigational drug and has not been approved by the FDA. Multiple Phase 2 trials have been completed, but the drug remains in clinical development and is not yet available as a licensed therapy.

What clinical trials is Presatovir in?

Presatovir has been studied in four completed Phase 2 trials: NCT02135614 in hospitalized adults with RSV, NCT02254408 in hematopoietic cell transplant recipients with upper respiratory tract RSV, NCT02254421 in hematopoietic cell transplant recipients with lower respiratory tract RSV, and NCT02534350 in lung transplant recipients with RSV.

How does Presatovir work?

Presatovir is a small molecule antiviral that targets the Respiratory Syncytial Virus fusion protein, inhibiting viral entry into host cells. By blocking this fusion process, the drug aims to prevent the virus from replicating and spreading within the respiratory tract.

Is Presatovir the same as GS-5806?

Presatovir is also known by the developmental code GS-5806. It is an investigational antiviral drug being studied for the treatment of Respiratory Syncytial Virus infection, and both names refer to the same compound developed by Gilead Sciences.
