Results of a phase 2b trial with GB001, a DP2 antagonist, in moderate-to-severe eosinophilic asthma.
(PubMed, Chest)
- "Although GB001 did not significantly reduce the odds of asthma worsening, reductions favoring GB001 were observed. Treatment effects were consistent regardless of high/low Type 2 phenotype. While the overall safety profile was acceptable, GB001 60 mg was associated with risk of liver injury."

Gossamer Bio Announces Fourth Quarter and Full-Year 2020 Financial Results and Provides Business Update
(Businesswire)
- "GB001: Oral DP2 Antagonist for Eosinophilic Asthma: Gossamer engaged with the FDA and the EMA about the clinical development path in asthma, and based off those interactions, Gossamer believes that there is a viable clinical development path for GB001, or its backup molecule, in asthma. Gossamer does not currently plan to move forward with GB001, or its backup molecule, in further clinical trials without a partner."

[VIRTUAL] IMPACT OF CHANGES IN THE 2019 GINA TREATMENT CLASSIFICATION: ASSESSMENT IN A REAL-WORLD SETTING
(CHEST 2020)
- "Overall, two-thirds of patients retained the same GINA Step classification across the 2018 and 2019 classifications, while one-third moved to a different step when applying GINA 2019. Most of the change occurred in GINA Steps 4 and 5; nearly half of patients classified as Step 4 according to 2018 criteria (high-dose ICS/LABA) moved to Step 5 when 2019 criteria were applied. CLINICAL IMPLICATIONS: The 2019 changes in the GINA recommendations allocated a higher proportion of patients to GINA Step 5."

These features endow GB001 with prolonged biologic effects that may be key to effectively treating chronic inflammation. GB001 is being evaluated in moderate-severe asthma and chronic rhinosinusitis (NCT03683576; NCT03956862)."

(ATS-I 2020)
- P2b | "GB001 is a differentiated antagonist as demonstrated by high potency, degree of insurmountability and slow disassociation from the DP2 receptor. This long residence time may allow GB001 to be relatively insensitive to changes in PGD 2 concentration, which may be beneficial in controlling inflammation. In addition, GB001 reduced lung infiltration of eosinophils and inflammatory cells and improved lung function in the HDM model of allergic asthma, providing further insights of the role of GB001 in this phenotype."

- "'The trends observed in the clinical endpoints from a 28-day study with a limited number of patients, especially those endpoints that reflect GB004's novel mechanism of action, such as histologic remission and mucosal healing, are very exciting,' said William Sandborn, M.D....Gossamer recently completed a pre-specified interim analysis of LEDA, its Phase 2b clinical study of GB001 in moderate-to-severe eosinophilic asthma. The interim analysis was based on approximately the first two thirds (~320) of patients who either completed or withdrew from the study...Gossamer has commenced initial Phase 3 planning...Topline results from LEDA continue to be expected in the second half of 2020...This patent is not due to expire before 2037."
