- HL192 (ATH-399A) was well tolerated with no major safety issues in any of the 76 participants.
- No serious treatment related adverse events were reported and such findings were proportional between placebo and dosed groups.
- PK results support once a day dosing.
ROCKVILLE, Md. and SEOUL, South Korea, Nov. 25, 2024 /PRNewswire/ — HanAll Biopharma, Daewoong Pharmaceutical and NurrOn Pharmaceuticals successfully completed their Phase 1 study of HL192 (ATH-399A), which is being developed as a disease-modifying therapy for Parkinson’s disease. The study met its primary endpoints of safety and tolerability in 5 different ascending dose groups, demonstrating significant progress in the treatment of this debilitating neurological disorder. This first-in-human study included single ascending dose (SAD), multiple ascending dose (MAD), and food effect components.
"We are extremely pleased to announce the completion of the first-in-human study," said Sean Jeong, MD, MBA, CEO of HanAll Biopharma. "Successfully demonstrating the safety and tolerability in healthy volunteers, including older adults, is a key step in our mission to develop a disease-modifying therapy for Parkinson’s disease. These findings bring hope to millions of patients and their families who are affected by this challenging condition."
"We are excited to report positive results for our Phase 1 trial, confirming the well-tolerated safety profile of HL192 (ATH-399A) in healthy participants and expect to launch the next clinical trial in people with Parkinson’s disease," said Deog Joong Kim, PhD., CEO of NurrOn Pharmaceuticals.
NurrOn was awarded a $1.7 million grant from The Michael J. Fox Foundation for Parkinson’s Research (MJFF) in support of the Phase 1 clinical trial of HL192 (ATH-399A), that initiated in the second half of 2023.
"The Michael J. Fox Foundation remains steadfast in our commitment to accelerate the development of better treatments for the more than 6 million people living with Parkinson’s disease around the world," said Katharina Klapper, principal of clinical research at MJFF. "The successful completion of the study’s Phase 1 HL192 (ATH-399A) trial marks a meaningful step forward in advancing today’s therapeutic pipeline."
Parkinson’s disease is a progressive neurological disorder that affects millions of people worldwide. Current treatments primarily focus on managing symptoms, but there is an urgent need for therapies that can alter the disease’s progression. HL192 (ATH-399A) represents a promising approach, targeting the underlying mechanisms of Parkinson’s disease to provide a more effective and long-lasting treatment.
The study enrolled 76 healthy participants. Participants in the SAD and food effect arms received HL192 (ATH-399A) once, while participants in the MAD arm received a single dose once a day for twelve days, with careful monitoring and assessment of safety and tolerability. The results demonstrated a favorable safety profile. Key findings include equivalent percentages of treatment emergent adverse events (TEAEs) between those who received treatment compared to those who received placebo, with no clear dose dependent trends. Additionally, all tested dose levels were well below the pre-determined NOAEL (no observed adverse effect level) concentrations, further confirming the safety and tolerability of the chosen dose levels.
HanAll and Daewoong plan to initiate the next clinical trial in people with Parkinson’s disease in collaboration with NurrOn. The study will further evaluate the safety of HL192 (ATH-399A). The companies remain dedicated to developing this important asset with the goal to improve patient lives in an area of great unmet need.

About NurrOn Pharmaceuticals
NurrOn Pharmaceuticals is a clinical-stage biopharmaceutical company dedicated to developing novel, targeted therapeutics for the treatment of Parkinson’s disease (PD) and other Nurr1-related incurable human disorders.
Through targeting Nurr1, the master regulator for dopaminergic neuron development and maintenance, we aim to develop a paradigm changing PD treatment to improve patients’ quality of life. While currently there are only symptomatic treatment options for patients with PD, there have not been any successful therapies to slow or prevent the progression of the disease. We believe that disease-modifying therapies will be achieved through targeting Nurr1, which has generated supportive data as a new druggable PD target. NurrOn was awarded a substantial grant from Michael J. Fox Foundation in support of the Phase 1 clinical trial of HL192 (ATH-399A), that initiated in the second half of 2023.
