SAN DIEGO, Aug. 09, 2021 (GLOBE NEWSWIRE) -- AnaptysBio, Inc.  (Nasdaq: ANAB), a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on emerging immune control mechanisms applicable to inflammation and immuno-oncology indications, today reported operating results for the second quarter ended June 30, 2021 and provided pipeline updates.

“We continue to make progress in advancing our wholly-owned pipeline and look forward to multiple clinical data readouts over the upcoming 18 months,” said Hamza Suria, president and chief executive officer of AnaptysBio. “The recent approval of JEMPERLI, which is the first AnaptysBio-generated antibody to be approved in the US and EU, validates AnaptysBio’s antibody discovery platform and provides additional revenues to support our capital-efficient business model.”   

Imsidolimab (Anti-IL-36 Receptor) Program

• Following an end-of-Phase 2 meeting with the FDA in Q2, we publicly disclosed trial designs for our imsidolimab generalized pustular psoriasis (GPP) Phase 3 trials, called GEMINI-1 and GEMINI-2.   We anticipate initiating GEMINI-1 in Q3 2021.   The primary endpoint of our Phase 3 program is the proportion of patients achieving clear or almost clear skin as determined by a Generalized Pustular Psoriasis Physician’s Global Assessment (GPPPGA) score of zero or 1 at week 4 of GEMINI-1, while GEMINI-2 is designed for 6 months of safety follow-up assessment.
• We continue to enroll GPP patients in our worldwide registry of GPP patients, called RADIANCE, which is designed to improve our understanding of GPP patient journeys and support enrollment of our GEMINI Phase 3 trials.   Medical claims analyses recently conducted by IQVIA indicate approximately 37,000 unique patients were diagnosed with GPP at least once, and approximately 15,000 unique patients were diagnosed with GPP at least twice, in the United States by a physician between 2017 and 2019 using the International Classification of Diseases 10th Revision (ICD-10) billing code pertaining to GPP (L40.1).
• Full data from our completed Phase 2 GALLOP trial of imsidolimab in GPP, including efficacy and safety of imsidolimab treatment through week 16, will be disclosed in an oral presentation at the European Academy of Dermatology and Venereology (EADV) Congress on October 2^nd, 2021.
• We are continuing to advance imsidolimab through Phase 2 clinical trials in multiple additional indications associated with IL-36 signaling dysfunction.   Our 120-patient placebo-controlled ACORN Phase 2 trial of imsidolimab in moderate-to-severe acne is anticipated to read out top-line data in the first half of 2022.   Imsidolimab is also being tested versus placebo in hidradenitis suppurativa, where our 120-patient HARP trial is anticipated to generate top-line data in the second half of 2022. We continue to enroll our 45-patient placebo-controlled EMERGE Phase 2 trial of imsidolimab in EGFR/MEK-mediated skin toxicities, where we anticipate an interim analysis by the end of 2021.   We also continue to enroll patients in our INSPIRE Phase 2 trial in ichthyosis where top-line data is anticipated during 2022.

Rosnilimab (Anti-PD-1 Agonist) Program

• We anticipate top-line data in Q4 2021 from our ongoing Phase 1 healthy volunteer clinical trial of rosnilimab, our wholly-owned PD-1 agonist antibody, designed to assess the safety, pharmacokinetics and pharmacodynamics of rosnilimab in single and multiple ascending dose cohorts.
• We plan to initiate a placebo-controlled Phase 2 clinical trial of rosnilimab in alopecia areata in Q4 2021.

ANB032 (Anti-BTLA Modulator) Program

• We are advancing ANB032, our wholly-owned BTLA modulator antibody, in a healthy volunteer Phase 1 single and multiple ascending dose clinical trial where top-line data is anticipated during the first half of 2022.

GSK Partnered Programs

• JEMPERLI (dostarlimab), our proprietary anti-PD-1 antagonist antibody, was approved by the FDA and the European Medicines Agency (EMA) during April 2021 for treatment of advanced or recurrent mismatch repair deficient endometrial cancer.   This is the first AnaptysBio-generated antibody, of eight currently under clinical development, to obtain regulatory approval. GSK has recently disclosed peak annual sales estimates of £1-£2 billion for JEMPERLI, and AnaptysBio will earn 8-25% royalties on global net sales of JEMPERLI. We received $20 million and $10 million milestone payments upon FDA and EMA approval of JEMPERLI, respectively.   We anticipate earning an additional $20 million milestone payment upon a second FDA BLA approval for JEMPERLI in pan-deficient mismatch repair tumors during the second half of 2021.   AnaptysBio is due an additional $15 million and $165 million upon certain JEMPERLI regulatory and commercial milestones, respectively.

Second Quarter Financial Results

• Cash, cash equivalents and investments totaled $396.3 million as of June 30, 2021, compared to $411.2 million as of December 31, 2020, for a decrease of $14.9 million. The decrease relates primarily to cash used for operating activities.
• Collaboration revenue was $30 million and $41.3 million for the three and six months ended June 30, 2021. The $30 million earned during the second quarter relates to milestone revenue for the US and EU approval of JEMPERLI (dostarlimab), compared to zero and $15 million of milestone revenue for the three and six months ended June 30, 2020.
• Research and development expenses were $25.3 million and $49.5 million for the three and six months ended June 30, 2021, compared to $17.9 million and $38.9 million for the three and six months ended June 30, 2020. The increase was due primarily to continued advancement of the Company’s clinical programs.
• General and administrative expenses were $5.2 million and $10.7 million for the three and six months ended June 30, 2021, compared to $4.7 million and $9 million for the three and six months ended June 30, 2020. The increase was due primarily to personnel-related expenses, including share-based compensation.
• Net loss was $0.4 million and $18.6 million for the three and six months ended June 30, 2021, or a net loss per share of $0.02, and $0.68, compared to a net loss of $21.5 million and $29.8 million for the three and six months ended June 30, 2020, or a net loss per share of $0.79 and $1.09.

Financial Guidance

AnaptysBio expects its net cash burn in 2021 will be less than $100 million. We anticipate that our cash, cash equivalents and anticipated revenues will fund our current operating plan at least into 2024.

About AnaptysBio

AnaptysBio is a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on unmet medical needs in inflammation. The Company’s proprietary anti-inflammatory pipeline includes imsidolimab, its anti-IL-36R antibody, previously referred to as ANB019, for the treatment of dermatological inflammatory diseases, including generalized pustular psoriasis, or GPP, acne, hidradenitis suppurativa, EGFRi skin toxicity and ichthyosis; its anti-PD-1 agonist program, rosnilimab, for treatment of certain autoimmune diseases where immune checkpoint receptors are insufficiently activated; and its BTLA modulator program, ANB032, which is broadly applicable to human inflammatory diseases associated with lymphoid and myeloid immune cell dysregulation. AnaptysBio’s antibody pipeline has been developed using its proprietary somatic hypermutation, or SHM platform, which uses in vitro SHM for antibody discovery and is designed to replicate key features of the human immune system to overcome the limitations of competing antibody discovery technologies. AnaptysBio has also developed multiple therapeutic antibodies in an immuno-oncology collaboration with GSK, including an anti-PD-1 antagonist antibody (JEMPERLI (dostarlimab-gxly)), an anti-TIM-3 antagonist antibody (cobolimab, GSK4069889) and an anti-LAG-3 antagonist antibody (GSK4074386), and an inflammation collaboration with Bristol-Myers Squibb, including an anti-PD-1 checkpoint agonist antibody (CC-90006) currently in clinical development.
