Neoleukin Therapeutics Announces Second Quarter 2022 Financial Results & Provides Corporate Update

Company to Host Conference Call Today, August 9, 2022, at 1:30 p.m. Pacific / 4:30 p.m. Eastern

SEATTLE, Aug. 09, 2022 (GLOBE NEWSWIRE) — Neoleukin Therapeutics, Inc., “Neoleukin” (NASDAQ:NLTX), a biopharmaceutical company utilizing sophisticated computational methods to design de novo protein therapeutics, today announced financial results for the second quarter ended June 30, 2022 and a midyear corporate update.

“Our focus at Neoleukin is the advancement of de novo proteins to solve important therapeutic challenges and address unmet medical needs,” said Jonathan Drachman, M.D., Chief Executive Officer of Neoleukin. “We are excited to be part of a revolutionary approach to creating therapeutic proteins that are not based on native sequences. Our first programs, including our lead product candidate, NL-201, were developed using sophisticated computational algorithms combined with directed evolution in the laboratory. We have now added machine learning and neural networks to our technological approach, enabling faster, more accurate development of increasingly complex proteins. Using these new processes, we have been able to add two new cytokine mimetics to our discovery pipeline this year.”

“At Neoleukin, we are excited to be testing NL-201, which we believe is the first fully de novo protein in clinical trials,” said Priti Patel, M.D., Chief Medical Officer. “We are pleased to have begun testing NL-201 in combination with pembrolizumab in mid-May of this year. We believe this is just one of many potential opportunities to harness the immune activating properties of NL-201 in novel combination regimens.”

NL-201 Update

Neoleukin is conducting a clinical trial of intravenous NL-201 in patients with advanced solid tumors. The trial is evaluating two different schedules and multiple dose levels in order to determine a recommended Phase 2 dose and schedule. Intermediate dose levels have been added to both schedules, which has extended the timeline to reach the anticipated Phase 2 dose. Dose escalation continues in both schedules, and Neoleukin now anticipates disclosing interim data in 2023.

In April 2022, Neoleukin announced the presentation of preclinical data at the American Association for Cancer Research (AACR) Annual Meeting, highlighting the potential for NL-201 to treat non-Hodgkin lymphoma as well as synergistic antitumor activity when NL-201 is combined with radiation therapy, including significant inhibition of tumor growth and increased survival in preclinical models.

In May 2022, Neoleukin announced treatment of the first patient in a combination arm evaluating the safety and efficacy of Neoleukin’s NL-201 in combination with Merck’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab), as part of Neoleukin’s ongoing Phase 1 trial. Up to 132 patients will be enrolled in the combination arm of the study, which is being conducted through a clinical collaboration and supply agreement with Merck (known as MSD outside the United States and Canada). The trial is assessing safety, pharmacokinetics, pharmacodynamics, immunogenicity, and antitumor activity. KEYTRUDA® is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

Research Updates

Technology: Neoleukin’s research team is actively engaged in the discovery of additional de novo cytokine mimetics as well as technological advances in order to accelerate the process from concept to proof of preclinical activity. Among these advances, the use of machine learning and neural networks have made it possible to design de novo proteins even when high-resolution structures have not yet been solved, using less compute resources and with a higher percentage of functional sequences. In addition to NL-201, Neoleukin has previously reported preclinical data for two de novo proteins: NL-CVX1, a decoy protein that mimics the human ACE2 binding site of the SARs-CoV2 spike protein and Neo-5171, an inhibitor of both IL-2 and IL-15 signaling.

Pipeline: Neoleukin is exploring an activator of T-regulatory cells for the treatment of inflammation and autoimmune diseases, a next generation IL-2/IL-15 agonist, and two additional undisclosed de novo cytokine mimetics for the treatment of cancer.

Summary of Financial Results

Cash Position: Cash, cash equivalents, and short-term investments totaled $116.5 million as of June 30, 2022, compared to $142.5 million as of December 31, 2021.

Based upon current internal infrastructure and pipeline initiatives, Neoleukin believes it has sufficient cash to fund operations through 2023.

R&D Expenses: Research and development expenses for the second quarter of 2022 increased to $11.0 million from $9.8 million for the second quarter of 2021. The increase was primarily due to increased clinical trial expenses related to NL-201.

G&A Expenses: General and administrative expenses for the second quarter of 2022 decreased to $4.9 million from $5.3 million for the second quarter of 2021. The decrease was primarily attributable to decreases in personnel-related and facility-related costs.

Net Loss: Net loss for the second quarter of 2022 was $15.7 million compared to a net loss of $15.1 million in the second quarter of 2021.

About NL-201

NL-201 is a de novo agonist of the IL-2 and IL-15 receptors, designed to expand cancer-fighting CD8 T cells and natural killer (NK) cells without any bias toward cells expressing the alpha receptor subunit (CD25). Previously presented preclinical data has demonstrated the ability of NL-201 to stimulate and expand CD8+ and NK cells at low doses with minimal impact on immunosuppressive regulatory T cells. Furthermore, NL-201 has demonstrated both monotherapy and combination activity across a wide range of preclinical syngeneic tumor models.
