21% TLX PLUNGE: Hagens Berman Urges Telix Investors to Act by Jan. 9 in Class Action Suit Over SEC Subpoena & FDA CRL on Manufacturing Failures

SAN FRANCISCO, Dec. 11, 2025

The complaint alleges that Telix and its executives materially overstated the developmental progress of its therapeutic candidates and misrepresented the reliability and regulatory compliance of its third-party supply chain and manufacturing partners.

"The Telix complaint alleges a dual regulatory failure: first the SEC apparently questioning the development disclosures, and then the FDA alleged to have rejected a BLA based on fundamental CMC (Chemistry, Manufacturing, and Controls) and Form 483 deficiencies at the third-party manufacturers," said Reed Kathrein, the Hagens Berman partner leading the litigation. "The complaint alleges these documented failures were material and allegedly concealed, making the company's claims of 'great progress' and 'truly global manufacturing capability' materially false."

The firm urges Telix investors who suffered substantial losses to contact the firm now to discuss their rights."

Alleged Misstatements, Concealment of CMC Deficiencies, and Investor Losses

The complaint alleges two distinct regulatory events that purportedly corrected the market's misperception of Telix's business and prospects:

• SEC Investigation into Drug Progress: Telix received an SEC Subpoena related to its disclosures on the development of its prostate cancer therapeutic candidates (TLX591/TLX592), suggesting misleading statements about the drugs' advancement.
  
  
• FDA Complete Response Letter (CRL): The FDA rejected the Zircaix application, citing severe deficiencies in Chemistry, Manufacturing, and Controls (CMC) and issuing Form 483 notices to two third-party supply chain partners. This allegedly revealed foundational weaknesses the company the complaint claims were concealed.
  
  
• Investor Damages: The cumulative effect of these disclosures allegedly caused Telix ADSs to fall sharply, including a 21% drop following the final regulatory news, leading to damages for investors who purchased TLX ADSs during the Class Period (Feb. 21, 2025 – Aug. 28, 2025)
