EVANSTON, Ill., May 14, 2020 (GLOBE NEWSWIRE) -- Aptinyx Inc. (Nasdaq: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, today reported financial results for the first quarter of 2020 and highlighted recent progress across the company’s clinical programs and pipeline of novel NMDA receptor modulators.

“In the midst of the COVID-19 global pandemic, the safety of our employees, colleagues, and patients participating in our clinical studies remains our top priority,” said Norbert Riedel, Ph.D., president and chief executive officer of Aptinyx. “Despite challenges introduced by the pandemic across our operations, we made great progress in the first quarter and subsequent period and I am very proud of the dedication and adaptability of our team. Thanks to those efforts, enrollment in our PTSD study has progressed exceedingly well and we expect to report data from that study late this year. With our strong balance sheet, we expect to be able to achieve additional important clinical data readouts across our pipeline of novel NMDA receptor modulators as well.”

First Quarter 2020 and Recent Highlights

• Achieved over 90% of target patient enrollment to date in Phase 2 exploratory study of NYX-783 in post-traumatic stress disorder (PTSD). In March, Aptinyx announced that enrollment of new patients in its exploratory Phase 2 study of NYX-783 in PTSD was continuing despite some disruptions introduced by the COVID-19 pandemic. In the weeks since, enrollment has continued to progress and, to date, over 90% of the target enrollment has been achieved. Following study completion, Aptinyx anticipates reporting data from this study late in 2020.
   
• Temporarily paused enrollment of new patients in three ongoing Phase 2 studies due to COVID-19. In March, Aptinyx announced the temporary suspension of new patient enrollment in its Phase 2 studies in painful diabetic peripheral neuropathy (DPN), fibromyalgia, and Parkinson’s disease cognitive impairment. Aptinyx anticipates providing updated guidance on the expected timing of study completion and data reporting for these studies in the future following the recommencement of enrollment.
   
• Strengthened financial position through the completion of a $35 million common stock offering. In January 2020, Aptinyx announced the closing of a public offering of common stock with gross proceeds totaling $35.1 million, inclusive of the full exercise of the underwriters’ option to purchase additional shares and before deducting underwriting discounts and commissions and offering expenses. The offering included participation from new and existing investors. The company’s current cash balance is expected to provide financial support into 2022.
   
• Published preclinical data in Movement Disorders journal demonstrating reversal of cognitive deficits with NYX-458 in primate model of Parkinson’s disease. In January 2020, Aptinyx announced a publication in Movement Disorders, the official journal of the International Parkinson and Movement Disorder Society, highlighting the results of a preclinical study of NYX-458 in a validated and translatable model of Parkinson’s disease in non-human primates. In the study, administration of NYX-458 resulted in a robust and enduring reversal of MPTP-induced cognitive deficits in primates.     

Upcoming Milestones

• Reporting data from Phase 2 exploratory, first-in-patient study of NYX-783 in patients with PTSD – late 2020.

Aptinyx anticipates providing updated guidance on the timing of data reporting for the following clinical studies at a future date:

• Phase 2 study of NYX-2925 in painful DPN.
• Phase 2 study of NYX-2925 in fibromyalgia.
• Phase 2 exploratory study of NYX-458 in Parkinson’s disease cognitive impairment.

First Quarter 2020 Financial Results

Cash Position: Cash and cash equivalents were $121.0 million at March 31, 2020 compared to $98.8 million at December 31, 2019. Aptinyx expects its current cash balance to support anticipated operations into 2022.

Collaboration Revenue: Revenue was $0.8 million for the first quarter of 2020 compared to $0.9 million for same period in 2019. Aptinyx’s revenue was derived from its research collaboration agreement with Allergan. The company does not rely on these revenues to fund its operations.

Research and Development (R&D) Expenses: R&D expenses were $11.1 million for the first quarter of 2020 as compared to $12.5 million for the same period in 2019. The decrease in R&D expenses was primarily driven by a reduction in employee compensation, partially offset by increased costs related to the initiation of the company’s two Phase 2b studies of NYX-2925 in chronic pain.

General and Administrative (G&A) Expenses: G&A expenses were $4.9 million for the first quarter of 2020 as compared to $5.7 million for the same period in 2019. The decrease of $0.8 million was primarily driven by a decrease in legal costs associated with patent-related matters.

Net Loss: For the first quarter of 2020, net loss was $14.7 million compared to a net loss of $16.7 million for the first quarter 2019.
