Study Endpoints

Primary Endpoints

To evaluate the annualized asthma exacerbation rate (AAER) in adult and adolescent subjects with severe uncontrolled asthma.
From Day 1 (randomization) to Week 52

The annual exacerbation rate is based on clinically significant (CS) exacerbations reported by the investigator in the electronic case (eCRF) over 52 weeks for subjects on GB-0895 as compared to placebo.

Number of participants with treatment related adverse events as assessed by CTCAE 5.0
Day 1 to Day 500

Secondary Endpoints

To evaluate the annualized asthma exacerbation rate (AAER) in adult and adolescent subjects with severe uncontrolled asthma and baseline eosinophils (EOS) < 300 cells/µL.
From Day 1 (randomization) to Week 52
Change from baseline in pre-bronchodilator (BD) forced expiratory volume in 1 second (FEV1)
From Day 1 (randomization) to Study Week 52
Change from baseline in Asthma Quality of Life Questionnaire AQLQ(S)12+ score

Frequently asked questions about GB-0895

What is GB-0895 used for?

GB-0895 is an investigational monoclonal antibody being developed for the treatment of asthma, including severe asthma. It is studied as an adjunctive therapy in adults and adolescents with severe uncontrolled asthma, and in adults with mild to moderate asthma or COPD.

What does GB-0895 target?

GB-0895 targets TSLP, a protein involved in airway inflammation. By binding to TSLP, the antibody is designed to modulate inflammatory pathways implicated in asthma. It is administered subcutaneously and is being evaluated in clinical trials for respiratory conditions.

Who is developing GB-0895?

GB-0895 is being developed by Generate Biomedicines, Inc., a biopharmaceutical company. The company is conducting clinical trials to evaluate the safety and efficacy of GB-0895 in patients with asthma and related respiratory conditions.

What phase is GB-0895 in?

GB-0895 is in Phase 1 clinical development, with an ongoing study in adults with mild to moderate asthma or COPD. Additionally, two Phase 3 trials in severe asthma are listed as recruiting, indicating the program has advanced to late-stage development.

What clinical trials is GB-0895 in?

GB-0895 is being studied in three trials: NCT07359846 (SOLAIRIA-2) and NCT07276724 (SOLAIRIA-1), both Phase 3 studies in severe uncontrolled asthma, and NCT07116889, a Phase 1 study in mild to moderate asthma or COPD. All trials are actively recruiting or ongoing.

Is GB-0895 the same as GB-0895 (SC)?

Yes, GB-0895 is also known as GB-0895 (SC), referring to its subcutaneous route of administration. This alternative name is used in clinical contexts to specify the delivery method of the investigational antibody.
