"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.

Progress in the development of a prognostic gene expression profile test in cutaneous squamous cell carcinoma (cSCC) was highlighted in an oral presentation. The total number of deaths from cSCC, one of the most common cancers in the U.S., is approaching or surpassing that from melanoma. Many patients with cSCC will have a favorable prognosis, but 25-40% of high-risk subsets will experience metastasis or develop recurrences. Current cSCC staging systems are evolving but more accurate methods of risk prediction are needed to appropriately direct workup and treatment. The goal of this development program is to identify and validate a clinical test that improves upon existing clinicopathologic staging systems to identify patients who have a high risk for regional/distant metastasis and enable more informed clinical management decisions.

In an ongoing development study, primary cSCC specimens with associated clinical outcome data were accrued from 18 centers. The discovery phase of the program included determining genes identified for their expression in recurrent and non-recurrent tumors. Researchers successfully identified genes that exhibited significant differential expression in cSCC samples from patients who experienced a recurrence, including several specific to regional/distant metastasis. In an archival training cohort of 122 patients, gene expression data from 140 candidate genes were used to identify a preliminary gene set and predictive algorithm.

To assess the predictive value of this assay, Kaplan-Meier survival analysis was performed in an independent validation cohort of 107 patients. Results from the analysis support the predictive value of the test to identify two groups of patients with significantly different risk for regional/distant metastasis (p<0.0001). The positive predictive value of the test in this preliminary validation study was 60%, which compares favorably to the performance of current staging systems in this cohort.

Based on these preliminary validation results, an expanded validation program for the cSCC prognostic test is now underway, including additional archival studies and a prospective validation study.

"The continued progress toward validation of this prognostic test for cSCC demonstrates that improvements in risk identification based on tumor biology are feasible," said Sarah T. Arron, M.D., Ph.D., University of California San Francisco and the San Francisco VA Health System, an investigator in the study. "Clinical use of a validated prognostic test such as this could help inform clinical decisions on staging and adjuvant therapy, and improve upon currently used staging systems."

Second study presented at ACMS

A second study presented as a poster at ACMS highlighted results from a meta-analysis evaluating the performance of the DecisionDx-Melanoma gene expression profile test in four unique, independent patient cohorts.

Results from this meta-analysis with 1,479 patients from four independent cohorts confirm that the DecisionDx-Melanoma test is a significant, independent predictor of recurrence and metastasis in patients with Stage I-III melanoma. Patients identified as highest risk (Class 2B) by the DecisionDx-Melanoma test were 2.9 times more likely to experience recurrence than those identified as lowest risk (Class 1A, p<0.0001), independent of other clinicopathologic features. The meta-analysis, a statistical method considered to be among the highest level of evidence (Level 1A) for prognostic tests, supports the use of the DecisionDx-Melanoma gene expression profile test to inform patient management decisions.

About Cutaneous Squamous Cell Carcinoma

Cutaneous squamous cell carcinoma (cSCC), a non-melanoma skin cancer, is one of the most common cancers. Approximately 200,000 patients per year are diagnosed with cSCC with high-risk features. Most patients have a favorable prognosis, but a subset of patients will develop metastasis and up to 15,000 patients each year die from their disease. As current staging parameters have a low positive predictive value, many more patients are considered high risk than actually develop metastatic disease. Conversely, many patients who develop metastatic disease are misidentified as low risk. This may lead to over and undertreatment of a substantial number of cSCC patients. To address this clinical need, Castle Biosciences is developing a gene expression profile test designed to improve upon current staging systems and identify patients with cSCC at high risk for metastasis or recurrence, in order to enable more informed clinical decisions regarding adjuvant therapy and other management options.

About Myelodysplastic Syndromes

Myelodysplastic syndromes (MDS) are conditions that can occur when the blood-forming cells in the bone marrow become dysfunctional and thus produce an inadequate number of circulating blood cells. It is frequently associated with the presence of blasts or leukemic cells in the marrow. This leads to low numbers of one or more types of circulating blood cells, and to the need for blood transfusions. In MDS, some of the cells in the bone marrow are abnormal (dysplastic) and may have genetic abnormalities associated with them. Different cell types can be affected, although the most common finding in MDS is a shortage of red blood cells (anemia). Patients with higher-risk MDS may progress to the development of acute leukemia.

"Aeglea built on its momentum from 2018 with a terrific start to the year, including the presentation of new compelling clinical data from the Phase 1/2 trial of pegzilarginase for Arginase 1 Deficiency," said Anthony G. Quinn, M.B Ch.B, Ph.D., president and chief executive officer. "We see marked and sustained reductions in plasma arginine in all patients with clinically meaningful improvements in mobility and adaptive behavior. We believe the emergent data from this trial reaffirms the design of our upcoming pivotal Phase 3 PEACE trial, with first patient dosing on track for this quarter."

Corporate Highlights

Pegzilarginase in Arginase 1 Deficiency: Continued progress towards commercialization of the Company’s lead program

Aeglea presented new positive Phase 1/2 data for pegzilarginase in patients with Arginase 1 Deficiency (ARG1-D) at the 2019 Annual Meeting of the Society for Inherited Metabolic Disorders (SIMD). The oral presentation was delivered by Dr. George Diaz, M.D., Ph.D., Division Chief of Medical Genetics in the Department of Genetics and Genomic Sciences at the Icahn School of Medicine at Mt. Sinai, New York, NY, and a Principal Investigator on the pegzilarginase Phase 1/2 trial. Highlights of the presentation included the following:

Plasma arginine reduction was statistically significant (p<0.001) at eight weeks with sustained control through longer-term dosing.
Five of five (100%) and eight of 14 (57%) patients showed overall clinical response (mobility or adaptive behavior) at 20 weeks and eight weeks, respectively. Clinical responses were effectively captured using mobility and adaptive behavior assessments.
Pegzilarginase was generally well tolerated. Serious adverse events included hypersensitivity and hyperammonemia. Hypersensitivity reactions were infrequent, managed with standard treatment and did not lead to any patient discontinuations.
Upcoming Events

Aeglea will present at the following conferences, with details regarding the date and time of the presentations and webcasts to be announced prior to the events.

Jefferies 2019 Healthcare Conference to be held June 4-7 in New York, NY.
BMO 2019 Prescriptions for Success Healthcare Conference to be held June 25 in New York, NY.
First Quarter 2019 Financial Results

As of March 31, 2019, Aeglea had available cash, cash equivalents and marketable securities of $123.7 million. Based on Aeglea’s current operating plan, management believes it has sufficient capital resources to fund anticipated operations through the first quarter of 2021.

Research and development expenses totaled $14.4 million for the first quarter of 2019, compared with $6.9 million for the first quarter of 2018. The increase was primarily due to expanded clinical development activity, investment in manufacturing and pre-commercial activities for Aeglea’s lead product candidate, pegzilarginase, and a ramp-up in manufacturing activities for our Homocystinuria program.

General and administrative expenses totaled $3.3 million for the first quarter of 2019, compared with $2.9 million for the first quarter of 2018. This increase was primarily due to additional employee headcount and compensation to support company growth.

Net loss totaled $17.2 million and $8.1 million for the first quarter of 2019 and 2018, respectively, with non-cash stock compensation expense of $1.1 million and $0.8 million for the first quarter of 2019 and 2018, respectively.

About Pegzilarginase in Arginase 1 Deficiency

Pegzilarginase is an enhanced human arginase that enzymatically depletes the amino acid arginine. Aeglea is developing pegzilarginase for the treatment of patients with Arginase 1 Deficiency, a rare debilitating disease presenting in childhood with persistent hyperargininemia, severe progressive neurological abnormalities and early mortality. Pegzilarginase is intended for use as an enzyme replacement therapy in patients to reduce elevated blood arginine levels. Aeglea’s Phase 1/2 data for pegzilarginase in patients with Arginase 1 Deficiency demonstrated clinical improvements and sustained lowering of plasma arginine. The Company intends to initiate its single, global pivotal Phase 3 PEACE trial designed to assess the effects of treatment with pegzilarginase versus placebo over 24 weeks with a primary endpoint of plasma arginine reduction.
