SAN DIEGO, Nov. 08, 2022 (GLOBE NEWSWIRE) -- 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, 2022 and provided pipeline updates.

“We are excited about the potential of our novel immune cell modulator pipeline, including our two checkpoint agonists in clinical-stage development, rosnilimab and ANB032. We believe their mechanisms of action, acting directly on cell types mediating disease pathology, have the potential to treat a broad range of autoimmune and inflammatory disorders” said Daniel Faga, interim president and chief executive officer of AnaptysBio. “We’re well capitalized to execute with over $590 million in cash at the end of Q3 as we move forward in our strategic portfolio review.”

Rosnilimab (Anti-PD-1 agonist) Program

• Rosnilimab, our investigational wholly owned anti-PD-1 agonist antibody, is in the ongoing AZURE Phase 2 clinical trial in moderate-to-severe alopecia areata, and we anticipate top-line data in Q1 2023.
  

ANB032 (Anti-BTLA agonist) Program

• ANB032, our investigational wholly owned anti-BTLA agonist antibody, will be advancing with a U.S. IND submission for an initial Phase 2 clinical trial in Q4 2022.
  

ANB033 (Anti-CD122 antagonist) Program

• ANB033, our investigational wholly owned anti-CD122 antagonist antibody, targets the common beta subunit shared by the IL-15 and IL-2 receptors. IL-15 signaling mediates the survival and maintenance of tissue resident memory T cells (T_RM). The presence of long-lived and persistent T_RM have been shown to drive tissue-specific immune-mediated inflammation. We anticipate submitting a U.S. IND in first half of 2024.
  

Imsidolimab (Anti-IL-36 receptor) Program

• Imsidolimab, our investigational wholly owned anti-IL-36R therapeutic antibody, is in Phase 3 trials in generalized pustular psoriasis (GPP), and we anticipate top-line data from the GEMINI-1 Phase 3 clinical trial in Q4 2023 and plan to outlicense imsidolimab prior to potential FDA approval.
  

GSK Partnered Programs

• PERLA, a head-to head Phase 2 trial of JEMPERLI (dostarlimab) vs. Keytruda in patients with metastatic non-squamous non-small cell lung cancer met its primary endpoint of objective response rate (ORR) of dostarlimab plus chemotherapy versus pembrolizumab plus chemotherapy as assessed by blinded independent central review per RECIST v1.1.
  • GSK will present full results, including the primary endpoint of ORR and the key secondary endpoint of progression-free survival, at the ESMO Immuno-Oncology Annual Congress on Friday, December 9^th.
• COSTAR, a Phase 2 trial of dostarlimab plus cobolimab, an anti-TIM-3 antagonist antibody, achieved pre-specified efficacy and safety criteria, and GSK is advancing both arms of the COSTAR Lung clinical trial from Phase 2 to Phase 3, testing both doublet and triplet combinations of dostarlimab plus chemotherapy, and cobolimab plus dostarlimab plus chemotherapy in advanced non-small cell lung cancer who have progressed on prior anti-PD-(L)1 therapy and chemotherapy.
  • Cobolimab was discovered at AnaptysBio and licensed to TESARO, Inc., (GSK) as part of the same collaboration agreement as dostarlimab.
  • AnaptysBio earned a $5 million milestone from GSK in October 2022 on initiation of the first Phase 3 trial with cobolimab.
• Sold our royalty interest on future global net sales of Zejula to a wholly-owned subsidiary of DRI Healthcare Trust for up to $45 million during Q3.
  • Received an upfront payment of $35 million and are eligible for a further $10 million from DRI upon FDA approval of Zejula for the treatment of endometrial cancer, for which the drug is currently in a fully-enrolled ongoing Phase 3 study, to the extent that such approval occurs on or before December 31, 2025.
    

Third Quarter Financial Results

• Cash, cash equivalents and investments totaled $590.5 million as of September 30, 2022, compared to $615.2 million as of December 31, 2021, for a decrease of $24.7 million. The decrease relates primarily to cash used for operating activities offset by cash received from the Zejula royalty sale and stock option exercises.
• Collaboration revenue was $1.3 million and $3.5 million for the three and nine months ended September 30, 2022, compared to $20.9 million and $62.2 million for the three months and nine months ended September 30, 2021. The decrease relates primarily to one development milestone achieved for JEMPERLI for the three months ended September 30, 2021, and four development milestones achieved for JEMPERLI for the nine months ended September 30, 2021, and no development milestones achieved during the nine months ended September 30, 2022.
• Research and development expenses were $22.1 million and $65.4 million for the three and nine months ended September 30, 2022, compared to $22.2 million and $71.7 million for the three and nine months ended September 30, 2021. The year-to-date decrease was due primarily to reduced clinical costs and manufacturing costs for the Company’s programs. The R&D non-cash, stock-based compensation expense was $1.5 million and $5.0 million for the three and nine months ended September 30, 2022, as compared to $1.8 million and $4.4 million in the same period in 2021.
• General and administrative expenses were $8.9 million and $27.2 million for the three and nine months ended September 30, 2022, compared to $5.4 million and $16.1 million for the three and nine months ended September 30, 2021. The increase was due primarily to $3.8 million of costs incurred from personnel changes in the first quarter of 2022 and non-cash stock compensation expense. The G&A non-cash, stock-based compensation expense was $4.7 million and $15.7 million for the three and nine months ended September 30, 2022, which includes $3.2 million of the $3.8 million one-time costs described earlier as compared to $2.6 million and $7.0 million in the same period in 2021.
• Net loss was $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, compared to a net loss of $6.7 million and $25.3 million for the three and nine months ended September 30, 2021, or a net loss per share of $0.24 and $0.92.
