Alterity Therapeutics Limited (NASDAQ:ATHE) stock is up during Tuesday’s session as the biotechnology company announced an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) regarding its pivotal Phase 3 program for ATH434 in treating Multiple System Atrophy (MSA).
The FDA agreed on key elements of the proposed Phase 3 trial design, including the study population and dosing regimen, following ATH434’s demonstration of a 48% slowing of disease progression compared to placebo in the Phase 2 study.
The pivotal Phase 3 trial activities are on track to initiate by year-end 2026.
“The successful outcome of the meeting is an important de-risking milestone and gives us confidence as we finalize the protocol and prepare to initiate trial activities by year-end 2026… I am confident that ATH434 is well-positioned to become a disease-modifying therapy for individuals living with MSA,” said David Stamler, CEO of Alterity Therapeutics.
Phase 2 Data Continued To Support ATH434 Development
In April, Alterity Therapeutics presented new data analyses from the Phase 2 trial of ATH434, demonstrating clinical efficacy in MSA patients.
ATH434-201 trial showed meaningful results utilizing MuSyCA demonstrated robust sensitivity to disease progression, with placebo participants worsening by approximately +9.7 points over 52 weeks.
Consistent with prior data, ATH434 slowed disease progression on the MuSyCA assessment.
The company received positive regulatory feedback following an FDA Type C Meeting in April regarding its planned Phase 3 development program for ATH434.
Alterity received written feedback supporting its plans related to the chemistry, manufacturing, and control (CMC) elements of the program.
The first Type C Meeting in March was related to clinical pharmacology and non-clinical development aspects of the program.
