FDA Grants Fast Track Status to ITM-94
ITM Isotope Technologies Munich SE (ITM), a leading German radiopharmaceutical biotech company, announced on November 17, 2025, that its diagnostic agent, ITM-94 (Ga-DPI-4452), has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA). This designation is specifically for the detection of clear cell renal cell carcinoma (ccRCC), a condition characterized by a high unmet medical need.
The FDA's decision was based on ITM-94's potential as a more effective, non-invasive diagnostic agent designed to improve outcomes for patients living with ccRCC.
Understanding ITM-94 and its Mechanism
ITM-94 is a gallium-68-radiolabeled PET imaging agent. It forms a theranostic pair with the therapeutic candidate ITM-91 (Lu-DPI-4452). Both agents are designed to target carbonic anhydrase IX (CAIX), a cell surface protein that plays a crucial role in the tumor microenvironment, promoting tumor growth, survival, invasion, and metastasis.
The diagnostic agent is currently being evaluated in Part D of an ongoing Phase 1/2 clinical trial (NCT05706129). This part of the trial assesses ITM-94's effectiveness in accurately detecting ccRCC in patients with indeterminate renal masses (IDRM) when compared to CT/MRI imaging, with histopathological confirmation of diagnosis.
Benefits of Fast Track Designation
The FDA's Fast Track designation is intended to facilitate the development and expedite the review of new drugs that treat serious conditions and fill an unmet medical need. For ITM-94, this designation offers several key advantages:
- More frequent meetings and written communication with the FDA to discuss the drug's development plan.
- Eligibility for Accelerated Approval and Priority Review if the requisite criteria are met.
- The possibility of a 'rolling review,' where the FDA can begin reviewing sections of the New Drug Application (NDA) as they are completed, rather than waiting for the entire submission.
Dr. Celine Wilke, chief medical officer of ITM, stated, 'The FDA's Fast Track designation is a validation of ITM-94's potential to aid in the non-invasive diagnosis of renal cell carcinoma.' She added that promising data from ongoing clinical trials suggest ITM-94 'could change how clinicians diagnose and stage patients across the broader ccRCC disease landscape, with potential utility in supporting clinical decision-making for indeterminate renal masses as well.'
ITM's Role in Radiopharmaceutical Innovation
ITM Isotope Technologies Munich SE, based in Garching / Munich, Germany, is a radiopharmaceutical biotech company focused on developing a new generation of radiomolecular precision diagnostics and therapeutics for hard-to-treat tumors. The company has a vertically integrated approach, supplying medical radioisotopes while advancing a pipeline of targeted treatments. ITM-94's Fast Track designation underscores the company's commitment to addressing significant unmet medical needs in oncology.

Fast Track doesn't mean it actually works. Still needs rigorous testing.

Phase 1/2? Too early to celebrate. Let's see the real data first.
Michelangelo
Non-invasive diagnosis is a game-changer. So much potential here.
Raphael
This development could significantly improve early detection for a serious condition, which is commendable. But given the 'Big Pharma' context, concerns about the eventual pricing and insurance coverage for such specialized radiopharmaceuticals are already surfacing.

Another 'breakthrough' that will be unaffordable for most. Big Pharma wins again.
