What is being measured

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

  1. Change From Baseline to Week 16 in Sino-Nasal Outcome Test (SNOT) 22 Total Score

    The SNOT-22 is a validated questionnaire to assess the impact of chronic rhinosinusitis (CRS) on quality of life and utilizes a 2-week recall period. It is a 22-item outcome measure on a 5-point category scale applicable to sinonasal conditions and surgical treatments. The total scores range from 0 to 110 with higher total scores implying greater impact of CRS on quality of life.

    Measured: Baseline, Week 16

Secondary outcomes (8)
  1. Change From Baseline to Week 16 in Lund-Mackay Score

    Lund-Mackay scores are based on centralized imaging data assessments and are scored by blinded central reading at the imaging core laboratory. The Lund-Mackay system is based on localization with points given for degree of opacification: 0=normal, 1=partial opacification, 2=total opacification. These points are then applied to each sinus (maxillary, anterior ethmoid, posterior ethmoid, sphenoid, and frontal sinus) on each side. The osteomeatal complex on each side is graded as 0=not occluded, or 2=occluded. The maximum score is 12 per side, for a total score ranging from 0 to 24.

    Measured: Baseline, Week 16

  2. Change From Baseline to Week 16 in Nasal Polyp Score (NPS)

    The bilateral endoscopic NPS is the sum of the right and left nostril scores, as evaluated by means of blinded, centrally read nasal endoscopy and ranges from 0 to 8. NP is graded based on polyp size: 0 = No polyps, 1 = Small polyps in the middle meatus not reaching below the inferior border of the middle turbinate, 2 = Polyps reaching below the lower border of the middle turbinate, 3 = Large polyps reaching the lower border of the inferior turbinate or polyps medial to the middle turbinate, and 4 = Large polyps causing complete obstruction of the inferior nasal cavity.

    Measured: Baseline, Week 16

  3. Time to First Response in NPS

    Response was defined as ≥ 1-point improvement from baseline.

    The bilateral endoscopic NPS is the sum of the right and left nostril scores, as evaluated by means of blinded, centrally read nasal endoscopy and ranges from 0-8. NP is graded based on polyp size: 0 = No polyps, 1 = Small polyps in the middle meatus not reaching below the inferior border of the middle turbinate, 2 = Polyps reaching below the lower border of the middle turbinate, 3 = Large polyps reaching the lower border of the inferior turbinate or polyps medial to the middle turbinate, and 4 = Large polyps causing complete obstruction of the inferior nasal cavity.

    Measured: up to Week 16

  4. Change From Baseline to Week 16 in Morning (AM) Nasal Congestion (NC) Score

    AM NC score was assessed using a 0 to 3 categorical scale (where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms).

    Measured: Baseline, Week 16

  5. Change From Baseline to Week 16 in AM Total Symptom Score (TSS)

    AM TSS is the sum of the scores from the 4 AM symptom categories (congestion and/or obstruction, anterior rhinorrhea, posterior rhinorrhea, loss of sense of smell) and ranges from 0-12. Each symptom category was assessed using a 0 to 3 categorical scale (where 0 = no symptoms, 1 = mild symptoms, 2 = moderate symptoms and 3 = severe symptoms).

    Measured: Baseline, Week 16

  6. Change From Baseline to Week 16 in University of Pennsylvania Smell Identification Test (UPSIT) Score

    The UPSIT test consists of four booklets, each containing 10 odorants with one odorant per page. The test-time is about 15 minutes. The stimuli are embedded in 10-50 μm diameter plastic microcapsules on brown strips at the bottom of each page. Above each odorant strip is a multiple-choice question with four alternative words to describe the odor. The participant is asked to release the odorant by rubbing the brown-strip with the tip of a pencil and to indicate which of 4 words best describes the odor. An UPSIT result is scored from 0 to 40 where a higher score indicates better olfaction.

    Measured: Baseline, Week 16

  7. Time to First Chronic Rhinosinusitis (CRS) Exacerbation

    Chronic rhinosinusitis exacerbation is defined as deterioration of CRS symptoms requiring treatment with an antibiotic, an anti-inflammatory drug, or a symptom reliever; an Emergency Department visit; or hospitalization.

    Measured: up to Week 16

  8. Percentage of Participants With a Treatment-Emergent Adverse Event (AE)

    An adverse event (AE) is any untoward medical occurrence in a participant, whether or not considered related to study drug. Abnormal laboratory test results or other safety assessments, including those that worsened from baseline, that were considered clinically significant in the medical and scientific judgment of the investigator were to be reported as AEs.

    Measured: From first dose of study drug through Week 20

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GB001 in people with Chronic Rhinosinusitis Without Nasal Polyps (CRSsNP) and Chronic Rhinosinusitis With Nasal Polyps (CRSwNP), run by GB001, Inc, a wholly owned subsidiary of Gossamer Bio, Inc. at 38 sites in 3 countries.

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 4 inclusion and 7 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 23 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 38 sites in United States, Ukraine, Czechia. 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 30 Jul 2021). 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?

Change From Baseline to Week 16 in Sino-Nasal Outcome Test (SNOT) 22 Total Score (time frame: Baseline, Week 16). 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 23 Aug 2021.
