Telix Pharmaceuticals Limited (TLX) Investigation:
The investigation is focused on the propriety of Telix’s statements concerning certain of its prostate cancer therapeutic candidates and also statements concerning its drug which would be used to help detect a specific type of kidney cancer.
While specific details of the firm’s investigation are evolving, the triggering event surfaced after hours on July 22, 2025, when Telix revealed that it is the subject of an SEC investigation into the company’s disclosures “regarding the development of the Company’s prostate cancer therapeutic candidates.”
Most recently, on August 28, 2025, Telix said it received a Complete Response Letter (“CRL”) from the FDA for the company’s Biologics License Application for Zircaix®, which is intended for the diagnosis and characterization of renal masses as clear cell renal cell carcinoma. The CRL identified deficiencies in chemistry, manufacturing, and controls and requested additional data to establish comparability of the drug product used in the phase 3 clinical trial and the manufacturing process intended for commercial use. Telix also revealed that the FDA documented notices of deficiency issued to its third-party manufacturing and supply chain partners that must be remediated.
Each of these events drove the price of Telix ADSs sharply lower.
“We’re investigating whether Telix may have misled investors about the development and commercial prospects of its candidates and whether other of the company’s therapies may be at issue,” said Reed Kathrein, the Hagens Berman partner leading the investigation.
