"The first quarter was a terrific start to our year, with a number of positive and encouraging developments in our lead clinical investigational program, pegzilarginase," said Anthony G. Quinn, M.B Ch.B, Ph.D., interim chief executive officer of Aeglea. "I’m excited that we are seeing the first evidence that marked and sustained reductions in plasma arginine with pegzilarginase translated into clinically relevant treatment effects for two patients with Arginase 1 Deficiency. We plan to continue to build on this momentum by reporting additional repeat dose data in patients with Arginase 1 Deficiency in the third quarter of 2018 and finalizing our pivotal study design by the end of the year. In addition, we expect to report topline safety and clinical data from our cancer trials in the fourth quarter of 2018.

"Our April follow-on offering provides us with capital to continue to advance our planned operations and further develop our capabilities as we transition into a pivotal study and start planning for a commercial launch. Our strong cash position and our worldwide commercial rights for pegzilarginase position us favorably to build on recent clinical achievements with investments focusing on accelerating our clinical and pipeline programs."

Corporate Update

Arginase 1 Deficiency:

Aeglea presented initial data that it believes demonstrated clinically relevant treatment effects with pegzilarginase in two Arginase 1 Deficiency patients after only eight weeks of dosing and confirmed the utility of standardized assessment tools in quantifying disease manifestations at the 2018 Annual Clinical Genetics Meeting of the American College of Medical Genetics and Genomics (ACMG) in April. This built upon data presented at the 2018 Annual Meeting of The Society for Inherited Metabolic Disorders (SIMD) that demonstrated pegzilarginase produces marked and sustained reductions in plasma arginine in patients with Arginase 1 Deficiency.
Aeglea expects to report additional pediatric and adult repeat dose data in patients with Arginase 1 Deficiency in the third quarter of 2018.
Cancer:

Aeglea dosed the first patients with pegzilarginase in two small cell lung cancer (SCLC) trials: the single-agent Phase 1 cohort expansion and the Phase 1/2 combination trial with KEYTRUDA, an anti-PD-1 therapy marketed by Merck (known as MSD outside the United States and Canada).
Aeglea presented Phase 1 dose escalation data regarding pegzilarginase in patients with advanced solid tumors at the 2018 Annual Meeting of the American Association for Cancer Research (AACR) (Free AACR Whitepaper) in April.
The Company expects to report topline data, including safety and clinical activity, for the advanced solid tumor cohort expansions and the SCLC combination trial in the fourth quarter of 2018.
Aeglea expects to initiate Phase 2 of its combination trial for patients with SCLC in the third quarter of 2018.
Upcoming Events

Aeglea will participate and provide a corporate update at the UBS Global Healthcare Conference in New York, May 21-23, 2018.

First Quarter 2018 Financial Results

As of March 31, 2018, Aeglea had available cash, cash equivalents and marketable securities of $43.5 million, which excludes approximately $37.7 million in net proceeds from a follow-on public offering which closed on April 23, 2018. Based on Aeglea’s current operating plan, management believes it has sufficient capital resources to fund anticipated operations through the middle of 2020.

Aeglea recognized grant revenues of $1.5 million in the first quarter of 2018, compared with $1.0 million in the first quarter of 2017. The grant revenues were the result of a $19.8 million research grant received from the Cancer Prevention and Research Institute of Texas (CPRIT). The revenue increase was primarily due to higher qualifying expenditures associated with the clinical trials for pegzilarginase in cancer patients in the first quarter of 2018 compared with the first quarter of 2017.

Research and development expenses totaled $6.8 million for the first quarter of 2018, compared with $4.9 million for the first quarter of 2017. The increase was primarily due to expanded clinical activity for Aeglea’s lead product candidate, pegzilarginase, as Aeglea advanced a Phase 1/2 clinical trial in patients with Arginase 1 Deficiency and initiated three single-agent cohort expansions in advanced solid tumor patients and a Phase 1/2 combination trial with KEYTRUDA in patients with small cell lung cancer.

General and administrative expenses totaled $2.8 million for the first quarter of 2018, compared with $2.3 million in the first quarter of 2017. This increase was primarily due to additional employee headcount and compensation costs to further strengthen Aeglea’s management team and support expanding research and development activities.

Net loss totaled $8.1 million and $6.2 million for the first quarter of 2018 and 2017, respectively.

Inducement Grants

Aeglea also announced today that the Compensation Committee of its Board of Directors has granted non-qualified stock options to purchase an aggregate of 21,000 shares of Aeglea’s common stock to three new employees under Aeglea’s 2018 Equity Inducement Plan.

The 2018 Equity Inducement Plan is used exclusively for the grant of equity awards to individuals who were not previously an employee or non-employee director of Aeglea (or following a bona fide period of non-employment), as an inducement material to such individual’s entering into employment with Aeglea, pursuant to Rule 5635(c)(4) of the NASDAQ Listing Rules.

The options have an exercise price of $9.76 per share, which is equal to the closing price of Aeglea’s common stock on May 3, 2018. Each of the option awards vests as to 25% of the shares on the one-year anniversary of its grant, with the remainder of the shares vesting ratably over 36 months thereafter
