Pipeline Updates

GB001: Oral DP2 Antagonist for Asthma and Allergic Disease

• Enrollment in the Phase 2b LEDA study in moderate-to-severe eosinophilic asthma is on track, with results from an interim analysis expected in the first half of 2020.
• Screening patients in the TITAN Phase 2 proof-of-concept study in chronic rhinosinusitis with and without nasal polyps is underway.
• In February 2019, Gossamer presented results of a post-hoc analysis of a GB001 study at the American Academy of Allergy, Asthma and Immunology (AAAAI) 2019 Annual Meeting. The analysis suggested that high baseline levels of Fractional exhaled Nitric Oxide (FeNO), a marker of airway inflammation, could potentially be used as a prognostic marker for GB001 response in the treatment of asthma, as marked reductions in FeNO levels as well as greater numeric improvements in lung function and asthma control were observed relative to placebo in patients with high baseline FeNO as compared to patients with low baseline FeNO. Gossamer plans to further assess the utility of FeNO as a prognostic marker in future studies.
• Initiation of a Phase 2 proof-of-concept study in chronic spontaneous urticaria is planned for the second half of 2019.

GB002:Inhaled PDGFR Inhibitor for Pulmonary Arterial Hypertension (PAH)

• Dosing of Phase 1 safety studies has been completed, and thus far the drug has been well tolerated with no serious adverse events observed to date.
• Site initiation and patient screening for a Phase 1b study in patients with PAH is expected in the second quarter of 2019.

GB004: Oral HIF-1α Stabilizer for Inflammatory Bowel Disease

• A Phase 1 safety study in healthy volunteers was recently completed, in which the drug was generally well tolerated with no serious adverse events observed to date.
• An Investigational New Drug Application (IND) for GB004 is now active, following a first quarter filing with the U.S. Food and Drug Administration (FDA).
• Screening patients in a Phase 1b study in active mild-to-moderate ulcerative colitis is underway.

GB1275: Oral CD11b Modulator for Oncology Indications

• An IND has been filed with the FDA and the initiation of a Phase 1/2 study in advanced solid tumor indications is planned for the second half of 2019, subject to the FDA 30-day review period.

Corporate Updates

Closed Initial Public Offering (IPO)

• In February 2019, Gossamer closed its IPO, which generated over $291 million in net proceeds.

Secured debt facility for up to $150 million

• In May 2019, Gossamer entered into a five-year $150 million senior debt facility, with $30 million funded at closing, and access to the remaining $120 million subject to the achievement of certain clinical development milestones and other customary conditions.

• Research and Development (R&D) Expenses: For the quarter ended March 31, 2019, R&D expenses were $25.0 million, including $1.3 million of stock-based compensation, compared to R&D expenses of $2.6 million for the quarter ended March 31, 2018.

This compared to G&A expenses of $2.6 million for the quarter ended March 31, 2018, which included $0.6 million of stock-based compensation. The increase was primarily attributable to personnel-related expenses, professional and legal fees, and stock-based compensation.
