"The Gossamer team enters 2021 excited and focused on clinical trial execution," said Faheem Hasnain, Co-Founder, Chairman and Chief Executive Officer of Gossamer. "Both seralutinib and GB004 are potentially paradigm shifting product candidates in indications of significant unmet patient need, and I am very proud of our team’s ongoing efforts to conduct our Phase 2 proof-of-concept studies for these programs despite the challenges of the pandemic."
Clinical-Stage Product Candidate Updates
Seralutinib (GB002): Inhaled PDGFR, CSF1R and c-KIT Inhibitor for PAH
Enrollment ongoing in the TORREY Study, a Phase 2 clinical trial in patients with PAH whose disease has progressed despite standard-of-care therapy. The primary endpoint is change in pulmonary vascular resistance (PVR) from baseline at week 24. Topline data from the TORREY study are expected in the first half of 2022, subject to developments in the ongoing COVID-19 pandemic.
Key opinion leader-led webcast and presentation regarding PAH and seralutinib (GB002) held on December 15, 2020 available through the "Events / Presentations" page in the "Investors" section of the Company’s website at www.gossamerbio.com.
GB004: Oral HIF-1α Stabilizer for Inflammatory Bowel Disease (IBD)
Enrollment ongoing in the SHIFT-UC Study, a Phase 2 clinical trial in patients with active UC despite treatment with 5-ASAs. The primary endpoint is proportion of patients with clinical remission at week 12. Topline data from the SHIFT-UC study are expected in the first half of 2022, subject to developments in the ongoing COVID-19 pandemic.
Key opinion leader-led webcast and presentation regarding IBD and GB004 held on February 18, 2021 available through the "Events / Presentations" page in the "Investors" section of the Company’s website at www.gossamerbio.com.
GB1275: Oral CD11b Modulator for Oncology Indications
Enrollment ongoing in a Phase 1 expansion cohort studying the recommended Phase 2 dose in KEYNOTE-A36, a Phase 1/2 clinical trial, including patients with gastric or esophageal cancer who have progressed after initial response to anti-PD-1 therapy and patients with advanced MSS colorectal cancer. Further Phase 1 data expected from this study in 2021.
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.
Financial Results for Quarter and Full Year Ended December 31, 2020
Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities as of December 31, 2020, were $512.6 million.

Research and Development (R&D) Expenses: For the quarter ended December 31, 2020, R&D expenses were $38.9 million compared to R&D expenses of $42.6 million for the same period in 2019. R&D expenses for the full year ended December 31, 2020, were $160.9 million compared to $143.4 million for the full year ended December 31, 2019. The increases were primarily due to an increase in expenses for GB004, seralutinib, GB1275 and preclinical programs.

IPR&D expenses for the full year ended December 31, 2020, were $23.4 million compared to $3.6 million for the full year ended December 31, 2019. The increases were primarily attributable to a $15.0 million payment to Aerpio in connection with the amendment to the in-license agreement of GB004 in 2020 and a milestone payment of $5.0 million in connection with the initiation of the first Phase 2 clinical trial of seralutinib in 2020.
