• EORTC QLQ-C30 subgroup results confirm broad and durable quality-of-life improvements across disease stages and metastasis status, complementing previously reported pain reduction and opioid-free outcomes
• Late-stage patients showed substantial improvements, suggesting ablation provided clinically meaningful changes even in advanced severe disease

THE WOODLANDS, TX, Nov. 17, 2025 (GLOBE NEWSWIRE) -- Autonomix Medical, Inc. (NASDAQ: AMIX) (“Autonomix” or the “Company”), a medical device company dedicated to advancing precision nerve-targeted treatments, today announced results from a post-hoc exploratory subgroup analysis of its previously reported first-in-human proof-of-concept study (PoC 1) evaluating the safety and effectiveness of delivering transvascular energy to ablate relevant problematic nerves and mitigate pain in patients with severe pancreatic cancer pain. The analysis evaluated patient-reported quality-of-life, symptom and functional outcomes as a secondary endpoint of the study using the EORTC QLQ-C30 scale (a validated measure of cancer-specific quality of life) across multiple patient subgroups, including tumor stage and metastatic status. Results from this post-hoc exploratory analysis suggested that Autonomix’s targeted ablation therapy may have produced improvements in symptom burden, functionality, and global quality of life following Autonomix’s targeted ablation therapy.

The analysis also provided new procedural findings that will be used to guide Autonomix’s U.S. clinical trial, which is on track to commence in 2026.

Key Findings from the Subgroup Analysis:

• Consistent Improvements Across All Responders: Across all responding patients, average symptom scores improved by 14.53 points at 4–6 weeks (n=9)² and 26.07 points at 3-months (n=6)², functionality increased by 8.15 and 25.56 points, and global quality of life improved by 8.33 and 18.06 points, respectively. All 3-month¹ results exceeded the EORTC threshold for clinically meaningful change (≥10 points).
• Advanced Disease in Stage 4, Distant Metastatic Subgroup Shows Strong Response: Patients with Stage 4 pancreatic cancer, with both distant and regional metastases, achieved a 32.48 point symptom improvement and 11.85 point functional gain by 4–6 weeks, maintaining significant benefit at 3-months (29.49 and 25.56 point improvements, respectively). Global quality of life scores improved by 19.44 points at 4-6 weeks and 25.00 points at 3-months. All timepoint results surpassed the EORTC’s threshold for clinically meaningful change. These findings confirm that ablation may provide durable, multidimensional relief even in metastatic and late-stage disease.

“These subgroup findings provide deeper insight into how and why our ablation approach is improving outcomes across varied patient types,” said Brad Hauser, President and Chief Executive Officer of Autonomix. “The fact that patients with late-stage and metastatic disease achieved large, durable improvements in symptoms, function, and global quality of life underscores the broad applicability and real-world impact of our therapy. While this is a retrospective post-hoc analysis with modest patient numbers that will require prospective validation, it will inform our future work in our larger, multicenter U.S. clinical trials.”

This post-hoc exploratory subgroup analysis of the PoC 1 study assessed EORTC QLQ-C30 domains – Symptoms, Functionality, and Global Health Status – at 24-hours, 7-days, 4–6 weeks, and 3-months post-procedure.

The data complement previously reported results showing nearly 60% reduction in VAS pain intensity and reported opioid-free outcomes by 4–6 weeks, potentially supporting a consistent link between pain control, functional recovery, and improved quality of life.

These subgroup insights will guide trial design, patient selection, and endpoint strategy for Autonomix’s upcoming U.S.-based multicenter clinical study, currently planned to begin in 2026, which will formally evaluate pain relief and quality-of-life outcomes as endpoints.

About the Proof-of-Concept Study

The goal of the PoC 1 study is to assess pain reduction via RF ablation. The Company’s catheter-based microchip sensing array used to detect and differentiate neural signaling was not used in this study and will be evaluated in future studies.

The primary objective of the study’s PoC 1 phase was to assess the success rate of ablating relevant nerves to mitigate pain in patients with pancreatic cancer pain utilizing RF ablation in a transvascular approach to the nerves in the region. Secondary objectives included assessing the incidence of device- and procedure-related adverse events up to 4-6 weeks post-procedure; estimating the change in pain levels from pre- to post-procedure; and estimating the change in quality of life from pre- to post-procedure. All patients who had a successful procedure were evaluated at 7-days, 4-6 weeks, and at 3-months post-procedure. All patients entered the study with severe abdominal pain from unresectable pancreatic cancer and had a life expectancy of 3 months or more.

The Company enrolled twenty (20) patients in PoC 1, including the first five (5) “lead-in” patients. Based on consistent, corresponding evidence that successfully met the trial objectives, the Company determined there was a sufficient number of patients and concluded its initial phase of the study. Notable findings from the study² included statistically significant pain relief as early as 24-hours post-procedure, providing patients with rapid relief. Responding femoral patients represented 84% of treated patients and had pain reduction that remained consistently positive at 7-days, 4-6 weeks and 3-months post-procedure with a mean 4.16 (53.3%), 4.67 (59.2%) and 5.08 (65.6%) pain reduction on the VAS pain scale, respectively. 100% of responding patients were able to go to zero opioid use at 7-days post-procedure, while 73% were at zero opioid use at 4-6 weeks post-procedure and 100% were at zero opioid use at 3-months post-procedure. Responding patients also reported an improved quality of life during end-stage cancer and the procedure demonstrated a strong safety profile.³

As previously announced, based on the positive results demonstrated in PoC 1, Autonomix has initiated a follow-on PoC 2 phase in a market expansion opportunity that will double the potential addressable market beyond pancreatic cancer pain by evaluating additional visceral cancers that signal pain through the Celiac Plexus and earlier stage pancreatic cancers with moderate to severe pain. The PoC 2 phase will provide a concentrated focus on interventional cancer pain management applications like pancreatic, gall bladder, liver, and bile duct, with potential further expansion in cardiology, oncology, gastroenterology, and other sectors where the Company has established key opinion leader relationships and emerging preclinical evidence.

¹ As to be expected in seriously ill patient populations, the 3-month post-procedure follow up ranged from three to five months due to disease progression and the patient’s inability of the patient to travel.

² Of the 20 subjects enrolled, three (3) patients with brachial access showed no improvement and one (1) patient was enrolled and not treated due to unsuccessful catheter placement because of an existing celiac trunk stenosis (narrowing of the vessel). 16 patients were treated using femoral access and three (3) patients using brachial access. 100% of patients (16) with femoral access responded to treatment, while the three (3) patients with brachial access showed no improvement in pain scores, representing a key procedural learning. At 7-days post procedure, data was captured on 16 responding patients. At 4-6 weeks post-procedure, a total of four (4) responders succumbed to their disease before the follow-up appointment which was attributed to disease progression and not related to the procedure. Three (3) responding patient VAS scores, three (3) responding patient quality of life scores and one (1) responding patient opioid status were not reported at the 4–6-week post-procedure follow-up due to the inability

³ There were no device or procedure-related serious adverse events. As to be expected with surgical procedures in seriously ill patient populations, there were 8 serious adverse events (6 subjects succumbed to their disease before the 4-6 week follow up, which were not related to the procedure, and 2 events resulting in hospitalization also unrelated to the procedure) and 14 adverse events (including 8 events of expected arterial constrictions due to spasms and temporary artery occlusion). In a separate clinical patient population of three subjects, there was a procedural-related serious adverse event of a hematoma at the access site resulting in hospitalization.
