Anaptys Announces Third Quarter 2023 Financial Results and
Provides Business Update
Initiated a global Phase 2b trial to treat rheumatoid arthritis (RA) with rosnilimab, our PD-1 agonist
Initiating in Q4 2023 a global Phase 2 trial to treat ulcerative colitis (UC) with rosnilimab
Announced positive top-line Phase 3 clinical trial results of imsidolimab (IL-36R) in generalized pustular psoriasis (GPP)
Reiterating cash runway through year-end 2026 and updating expected year-end 2023 cash and investments of $400 to $410 million
SAN DIEGO, Nov. 2, 2023 — AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics, today reported operating results for the third quarter ended September 30, 2023 and provided a business update.
“We’ve made strong progress this quarter executing against our multi-year plan to develop best-in-class immune cell modulators to drive differentiated clinical outcomes in heterogeneous, systemic autoimmune and inflammatory diseases,” said Daniel Faga, president and chief executive officer of Anaptys. “Enrollment is ongoing in our global Phase 2b trials in atopic dermatitis for ANB032, our BTLA agonist, and rheumatoid arthritis for rosnilimab, our PD-1 agonist, while also initiating a global Phase 2 trial in ulcerative colitis for rosnilimab in Q4 2023.”
Updates on Wholly Owned Immune Cell Modulator Pipeline
Rosnilimab (PD-1 agonist antibody)
Initiated in August a global Phase 2b trial in moderate-to-severe RA
420-patient placebo-controlled trial assessing three dose levels of subcutaneously administered rosnilimab (randomized 1:1:1:1) for a 12-week treatment duration on well-established endpoints, including DAS28-CRP, CDAI and ACR20/50/70
At Week 14, rosnilimab-treated patients who achieve low disease activity, defined as CDAI<=10, are eligible to be dosed for an additional 16-week all-active treatment period and then followed for a three-month off-drug follow-up period
Top-line Week 12 data anticipated by mid 2025
Anticipate initiation in Q4 2023 of a global Phase 2 trial in moderate-to-severe UC
130-patient placebo-controlled trial assessing two dose levels of subcutaneously administered rosnilimab (randomized 1:1:1) for a 12-week treatment duration on well-established endpoints, including clinical response on modified Mayo score (mMS), clinical remission on mMS and endoscopic remission
Rosnilimab and placebo-treated patients who achieved clinical response on mMS are eligible to continue on their assigned treatment for an additional 12 weeks, while patients on placebo who are non-responders will be crossed over to the high-dose rosnilimab treatment arm, in an all-active treatment period and then followed for a three-month off-drug follow-up period
Top-line Week 12 data anticipated by H1 2026
Hosted a virtual PD-1 Agonist (Rosnilimab) R&D Event in October 2023

Enrollment ongoing for global Phase 2b trial in moderate-to severe atopic dermatitis (AD)
160 patient placebo-controlled trial assessing three dose levels of subcutaneously administered ANB032 (randomized 1:1:1:1) for a 14-week treatment duration and then followed for a six-month off-drug follow-up period on well-established endpoints, including EASI75 and IGA 0/1
Top-line Week 14 data anticipated by year-end 2024
Presented poster on ANB032’s previously reported healthy volunteer Phase 1 data and a trial-in-progress poster presentation on ANB032’s Phase 2b study in moderate-to-severe AD at the 32 European Academy of Dermatology and Venerology (EADV) Congress in October 2023

Updates on Legacy Clinical-Stage Cytokine Antagonist Programs Available for Out-Licensing
Announced positive top-line Phase 3 clinical trial results of imsidolimab (IL-36R) in generalized pustular psoriasis (GPP)
53.3% of patients who received a single dose of 750mg IV imsidolimab achieved GPPPGA 0/1 (clear or almost clear) at Week 4 (primary endpoint), compared to 13.3% of patients on placebo (p=0.0131)
Demonstrated favorable safety and tolerability with no SAEs, low incidence and no increase of infections vs. placebo and no cases of DRESS or Guillain-Barre in imsidolimab-treated patients
Only one of 30 (3.3%) imsidolimab-treated patients had detectable ADA, which were non-neutralizing
Intend to out-license imsidolimab in 2024
Updates on GSK Immuno-Oncology Financial Collaboration
GSK anticipates top-line data in H2 2024 from COSTAR Lung Phase 3 trial comparing cobolimab, a TIM-3 antagonist, plus dostarlimab, a PD-1 antagonist, plus docetaxel to dostarlimab plus docetaxel to docetaxel alone in patients with advanced NSCLC who have progressed on prior anti-PD-(L)1 therapy and chemotherapy

Year-End Cash Guidance
Reiterating cash runway through year-end 2026 with updated expected year-end 2023 cash and investments of $400 to $410 million
Third Quarter Financial Results
Cash, cash equivalents and investments totaled $453.3 million as of September 30, 2023, compared to $584.2 million as of December 31, 2022, for a decrease of $130.9 million. The decrease relates to cash used for the $50 million stock repurchase program and operating activities.
Collaboration revenue was $3.3 million and $8.2 million for the three and nine months ended September 30, 2023, compared to $1.3 million and $3.5 million for the three and nine months ended September 30, 2022. The change is due primarily to increased royalties recognized for sales of Jemperli.
Research and development expenses were $30.9 million and $98.8 million for the three and nine months ended September 30, 2023, compared to $22.1 million and $65.4 million for the three and nine months ended September 30, 2022. The increase was due primarily to manufacturing and development costs for rosnilimab, ANB032 and ANB033. The R&D non-cash, stock-based compensation expense was $2.2 million and $7.7 million for the three and nine months ended September 30, 2023 as compared to $1.5 million and $5.0 million in the same period in 2022.
General and administrative expenses were $10.2 million and $31.7 million for the three and nine months ended September 30, 2023, compared to $8.9 million and $27.2 million for the three and nine months ended September 30, 2022. The G&A non-cash, stock-based compensation expense was $5.6 million and $17.4 million for the three and nine months ended September 30, 2023 as compared to $4.7 million and $15.7 million in the same period in 2022.
Net loss was $37.3 million and $121.4 million for the three and nine months ended September 30, 2023, or a net loss per share of $1.41 and $4.49, compared to a net loss of $33.5 million and $102.3 million for the three and nine months ended September 30, 2022, or a net loss per share of $1.18 and $3.64.
About Anaptys
Anaptys is a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics. It is developing immune cell modulators, including two checkpoint agonists in clinical-stage development, for autoimmune and inflammatory disease: rosnilimab, its PD-1 agonist, in a Phase 2b trial for the treatment of rheumatoid arthritis and a planned Phase 2 trial for the treatment of ulcerative colitis; and ANB032, its BTLA agonist, in a Phase 2b trial for the treatment of atopic dermatitis. Its preclinical immune cell modulator portfolio includes ANB033, an anti-CD122 antagonist antibody, for the treatment of autoimmune and inflammatory diseases. In addition, Anaptys has developed two cytokine antagonists available for out-licensing: imsidolimab, an anti-IL-36R antagonist, in Phase 3 for the treatment of generalized pustular psoriasis, or GPP, and etokimab, an anti-IL-33 antagonist for the treatment of respiratory disorders that is Phase 2/3 ready. Anaptys has also discovered multiple therapeutic antibodies licensed to GSK in a financial collaboration for immuno-oncology, including an anti-PD-1 antagonist antibody (Jemperli (dostarlimab-gxly)) and an anti-TIM-3 antagonist antibody (cobolimab, GSK4069889) in second line NSCLC.
