The update provided clarity around the planned Phase 3 development pathway, with Alterity confirming that trial preparation activities remain on track for initiation by year-end 2026.

While Alterity’s share price remains down 25.71% over the past year, the latest announcement provided investors with visibility on the next stage of ATH434 development, alongside updates on the company’s financial position, scientific engagement and strategic funding discussions.

Alterity Therapeutics Focuses on Disease-Modifying Treatments for Neurodegenerative Disorders

Alterity Therapeutics is a clinical-stage biotechnology company focused on developing treatments designed to address underlying disease mechanisms associated with neurodegenerative conditions. The company’s primary development focus is Multiple System Atrophy and related Parkinsonian disorders.

Its lead asset, ATH434, is being developed as a potential disease-modifying treatment for MSA. According to the company, ATH434 has demonstrated clinically meaningful efficacy in a randomised, double-blind, placebo-controlled Phase 2 clinical trial involving participants with MSA. Alterity has also reported positive data from an open-label Phase 2 clinical trial involving participants with advanced MSA.

Beyond ATH434, the company maintains a broader drug discovery platform focused on generating patentable chemical compounds targeting neurological disease pathways.

The company operates across Melbourne, Australia, and San Francisco, USA, with its current focus centred on advancing ATH434 toward late-stage clinical development.

FDA Alignment Provides Greater Clarity for ATH434 Phase 3 Development

A key development during Q4 FY26 was Alterity’s successful End-of-Phase 2 meeting with the FDA, where the company reached alignment regarding the proposed registrational pathway for ATH434 in MSA.

During discussions, the FDA indicated that a single pivotal Phase 3 trial combined with confirmatory evidence could potentially provide the required data package to support an approval application. Alterity expects data generated from its ATH434-201 Phase 2 clinical trial to contribute as confirmatory evidence.

The company stated that this regulatory alignment represents an important milestone in the development pathway of ATH434 and provides greater clarity as it moves toward late-stage clinical evaluation.

The planned Phase 3 program is expected to include approximately 200 patients, who will be randomly assigned in a 1:1 ratio to receive either ATH434 50 mg or matching placebo treatment twice daily over a 12-month period.

The FDA also reached alignment with Alterity on several important Phase 3 trial design elements, including the study population, treatment approach and the use of the 11-item UMSARS Part I rating scale as the primary endpoint.

Secondary endpoints assessing additional areas of impairment associated with MSA were also agreed upon, while the FDA indicated that the anticipated size of the safety database at the completion of the trial was reasonable.

Alterity plans to provide an open-label extension option for participants who complete the Phase 3 trial, allowing continued treatment while also contributing additional safety information for ATH434.

Phase 3 Preparation Continues Ahead of Planned Trial Start

Alongside regulatory progress, Alterity continued preparations required for the transition into Phase 3 development.

In April 2026, the company announced positive FDA feedback following a Type C meeting related to chemistry, manufacturing and control (CMC) requirements for the Phase 3 program.

During the latest quarter, Alterity confirmed that it successfully manufactured the first registration batch of ATH434 for use in the planned pivotal trial.

The company is continuing activities required to support the expected commencement of Phase 3 trial activities by the end of 2026.

Scientific Research Adds Further Support to ATH434 Development Program

Alterity continued its engagement with the global neurology research community during the quarter through presentations at international scientific conferences and publication of research findings.

At the American Academy of Neurology (AAN) Annual Meeting in April 2026, the company presented an analysis using the newly described MSA Combined Outcome Assessment (MuSyCA) composite scale. The analysis incorporated components from UMSARS Parts I and II and showed that ATH434 slowed functional decline compared with placebo at Week 52, consistent with previously reported activity using the 11-item UMSARS Part I measurement.

In May 2026, a peer-reviewed publication in NeuroImage highlighted research from Alterity’s bioMUSE Natural History Study. The study examined quantitative susceptibility mapping (QSM) of brain iron and found that the imaging approach could identify disease-specific iron accumulation in MSA, distinguish MSA from Parkinson’s disease and correlate with clinical severity.

During the same period, Alterity delivered three international scientific presentations at the International Society for Magnetic Resonance in Medicine (ISMRM), the Movement Disorder Society of Australia and New Zealand Scientific Meeting, and the MSA Symposium at University College London.

These presentations covered QSM imaging, cerebrospinal fluid neurofilament light chain analyses and swallowing outcome data supporting ATH434’s mechanism as an iron chaperone.

The company also hosted a virtual key opinion leader event featuring specialists from Harvard Medical School and Vanderbilt University Medical Center to discuss the treatment landscape in MSA and the ATH434 development program.

Strategic Funding Discussions Continue as Company Advances Clinical Program

Alongside clinical development activities, Alterity continues to evaluate strategic funding and partnering alternatives to support the advancement of ATH434.

The company stated that it is engaged in discussions with several pharmaceutical companies while conducting a structured evaluation process with support from external advisers.

The objective of this process is to assess potential partnerships and funding pathways while maintaining flexibility around the future development of ATH434.

Alterity remains focused on identifying approaches that support the advancement of its clinical program and maximise long-term shareholder value.

Financial Position Strengthened With Cash Balance and R&D Refund

Alterity reported cash and cash equivalents of A$37.3 million as at 30 June 2026.

During the quarter, operating cash outflows were A$7.72 million, with research and development expenditure representing the largest component of operating payments.

The quarterly cash flow report showed net cash used in operating activities of A$7.17 million, while the company ended the quarter with cash and cash equivalents of A$37.318 million.

Subsequent to the quarter ending, Alterity received its Australian Government R&D Tax Incentive refund for the 2025 financial year. The refund totalled A$3.98 million, including A$43,117 in interest.

The company reported that these funds support continued development activities across its clinical programs.

Payments to related parties during the quarter totalled A$309,000, which included non-executive director fees, managing director salary, consulting fees, remuneration and superannuation payments at commercial rates.

Board Expansion and Corporate Updates

During April 2026, Alterity strengthened its Board of Directors with the appointment of Ms Ann Cunningham as an independent Non-Executive Director.

The company noted that Ms Cunningham’s appointment brings global commercial and strategic experience as Alterity moves toward late-stage development activities in MSA.

Following shareholder approval at the Extraordinary General Meeting held on 29 May 2026, the company also completed a 1-for-50 share consolidation.
