"2019 is set to be an important year for AnaptysBio, with multiple top-line data readouts from our wholly-owned pipeline, initiation of a new Phase 2b trial of etokimab in eosinophilic asthma and submission of an IND for our next development candidate in our wholly-owned pipeline," said Hamza Suria, president and chief executive officer of AnapytsBio. "We look forward to advancing each of these programs as we work to bring novel treatments to patients with severe inflammatory diseases."

Etokimab (ANB020 Anti-IL-33 Program)

In September 2018, the Company reported positive interim top-line data from its Phase 2a proof-of-concept clinical trial of etokimab in adult patients with severe eosinophilic asthma. The Company will present the full data from this trial at the 2019 European Academy of Allergy and Clinical Immunology (EAACI) Congress. AnaptysBio also plans to initiate a multi-dose Phase 2b randomized, double-blinded, placebo-controlled trial of etokimab in eosinophilic asthma in 2019.

The Company is conducting a Phase 2b randomized, double-blinded, placebo-controlled, multi-dose study in 300 adult patients with moderate-to-severe atopic dermatitis, also referred to as the ATLAS trial, to assess different dose levels and dosing frequencies of subcutaneously-administered etokimab, with top-line data expected in the second half of 2019.

AnaptysBio is conducting a randomized, placebo-controlled Phase 2 trial in approximately 100 adult patients with chronic rhinosinusitis with nasal polyps, also referred to as the ECLIPSE trial. Patients are being treated with two multi-dosing frequencies of subcutaneously-administered etokimab or placebo, each in combination with mometasone furoate nasal spray as background therapy. The Company anticipates top-line data from the ECLIPSE trial will be available in the second half of 2019.

ANB019 (Anti-IL-36 Receptor Program)

The Company is conducting a single arm, open-label Phase 2 trial of ANB019 in approximately 10 patients with generalized pustular psoriasis, or GPP, also known as the GALLOP trial, with top-line data expected in mid-2019.

The Company is conducting a randomized, placebo-controlled, multi-dose Phase 2 trial in 50 patients with palmoplantar pustulosis, or PPP, also known as the POPLAR trial, with top-line data anticipated in the first half of 2020.
First Quarter Financial Results

Cash, cash equivalents and investments totaled $484.2 million as of March 31, 2019 compared to $500.2 million as of December 31, 2018, for a decrease of $16.0 million. The decrease primarily relates to cash used for operating activities.

Research and development expenses were $20.6 million for the three months ended March 31, 2019, as compared to $11.8 million for the three months ended March 31, 2018. The increase was primarily due to continued advancement of the Company’s etokimab and ANB019 clinical programs and additional

personnel-related expenses including share-based compensation during the three months ended March 31, 2019.

General and administrative expenses were $4.1 million for the three months ended March 31, 2019, as compared to $3.9 million for the three months ended March 31, 2018. The increase was primarily attributable to additional personnel-related expenses, including share-based compensation.

Net loss was $22.1 million for the three months ended March 31, 2019, or a net loss per share of $0.82, as compared to a net loss of $15.1 million for the three months ended March 31, 2018, or a net loss per share of $0.63.
Financial Guidance
AnaptysBio expects that its cash, cash equivalents and investments will fund its current operating plan at least through the end of 2020.
About Etokimab
Etokimab, previously referred to as ANB020, is an antibody that potently binds and inhibits the activity of interleukin-33, or IL-33, a pro-inflammatory cytokine that multiple studies have indicated is a central mediator of atopic diseases, which AnaptysBio believes is broadly applicable to the treatment of atopic inflammatory disorders, such as atopic dermatitis, eosinophilic asthma, chronic rhinosinusitis with nasal polyps, or CRSwNP, and potentially other allergic conditions. Following completion of a healthy volunteer Phase 1 trial of etokimab, AnaptysBio continued clinical development of etokimab into a Phase 2a trial for moderate-to-severe adult atopic dermatitis and a placebo-controlled Phase 2a trial in severe adult eosinophilic asthma patients. AnaptysBio is conducting its ATLAS trial, a randomized, double-blinded, placebo-controlled multi-dose Phase 2b clinical trial of etokimab in 300 moderate-to-severe adult atopic dermatitis patients where top-line data is anticipated in the second half of 2019. The Company is conducting its ECLIPSE trial, a randomized, double-blinded, placebo-controlled Phase 2 trial of etokimab in approximately 100 adult patients with CRSwNP with top-line data anticipated in the second half of 2019. AnaptysBio also plans to initiate a randomized, double-blinded, placebo-controlled, multi-dose Phase 2b trial of etokimab in patients with eosinophilic asthma in 2019.
About ANB019
ANB019 is an antibody that inhibits the function of the interleukin-36-receptor, or IL-36R, which AnaptysBio plans to initially develop as a potential first-in-class therapy for patients suffering from generalized pustular psoriasis, or GPP, and palmoplantar pustulosis, or PPP. AnaptysBio has previously presented data from this Phase 1 clinical trial, which demonstrated favorable safety, pharmacokinetics and pharmacodynamic properties that supported advancement of ANB019 into Phase 2 studies. AnaptysBio is conducting its GALLOP trial, a Phase 2 study of ANB019 in GPP where top-line data is anticipated in mid-2019, and its POPLAR trial, a Phase 2 study in PPP where top-line data is anticipated in the first half of 2020.
