Theranostics

Nuclear pharmacy is having something of a moment right now and more than ever has far-reaching promise as an integral component of modern medicine. This fusion of radiopharmaceuticals with diagnostic imaging is an exciting journey that has yet to reach its zenith. 

Theranostics — therapeutics and diagnostics — involves pairing diagnostic biomarkers with therapeutic agents that share a specific target in diseased cells or tissues. Theranostics is a game-changer in personalized medicine. It uses one radioactive drug to identify (diagnose) and a second radioactive drug to deliver therapy to treat the main tumor and any metastatic tumors.

Theranostics is not a buzzword; it’s a precision oncology powerhouse. From thyroid to liver, neuroendocrine to prostate, theranostics is on the cusp of redefining cancer treatment.

Theranostics: A Glimpse into Personalized Medicine

Theranostics is reshaping medical care by targeting disease states through molecular imaging and radioisotopes. This approach is paving the way for personalized medicine, with the most common applications being in the treatment of various cancers. 

When combined with molecular imaging, theranostics offers a level of precision in oncology that is known to surpass traditional chemotherapy. This two-pronged approach to diagnosing and treating cancers through the use of radiotracers has the potential to play a pivotal role in personalized medicine, offering more precise and effective treatments for a wide range of diseases.

Challenges on the Path to Widespread Adoption

Despite its potential, the field of theranostics faces hurdles in becoming a standard of care for more patients. The field is relatively small, expensive to operate within, and often short-staffed. It also requires more regulatory and research support to further fulfill its potential in personalized medicine. 

While the landscape of nuclear medicine is globally diverse, it is shaped by unique regulatory frameworks and educational prerequisites. At the intersection of various scientific disciplines, theranostics is an advanced field requiring the expertise of a broad spectrum of professionals — from radiochemists and nuclear physicists to radiopharmacists, engineers, technologists, physicians, and healthcare specialists. 

The technical challenges of theranostics are numerous: 

  • need for standardized and efficient protocols 
  • formation of interdisciplinary teams
  • incorporation into clinical guidelines
  • education and training

There are also economic concerns surrounding research and development, comparative cost-utility analysis, and adequate reimbursement. Biomedical quandaries abound as well – more clinical trials are needed of every type, plus all therapies need to be evaluated, and new therapies and applications must be developed.

Cross-Industry Collaborations and Clinical Trials

Cross-industry collaborations among clinical researchers, radiopharmaceutical manufacturers, and diagnostic imaging companies are pivotal in advancing theranostics. These collaborations are crucial in developing comprehensive patient care solutions, enabling accurate patient selection, and monitoring therapy responses.

As a collaborator and partner in the advancement of theronastics, Sirona supports just about every nuclear medical product and device needed for treatment. The FDA-approved Sirona Infusion Pump and Tubing, for example, is an easy front-loading product that automatically senses and accommodates the size of numerous syringe manufacturers.  

Clinical trials are also essential in cultivating theranostics. Radiopharmaceuticals must demonstrate efficacy and safety in specific applications to obtain FDA approval and become a part of the treatment protocol. For instance, patients with metastatic, castration-resistant prostate cancer can only qualify for theranostic treatments after unsuccessful hormone and chemotherapy options.

U.S. FDA Approval: Ensuring Safety and Efficacy

In the United States, the path to implementing theranostic approaches is intricately tied to regulatory approval and reimbursement mechanisms. The role of the Food and Drug Administration (FDA) is pivotal, extending beyond patient safety to foster the continued growth of established theranostic methodologies. 

Products that are FDA approved can help elevate both safety and the use of theranostics as a diagnostic and treatment modality.  

FDA approval serves as the cornerstone of patient care safety in the United States. Radiopharmaceuticals used in theranostics must demonstrate not only their efficacy but also their safety in specific applications. These rigorous evaluations are necessary to ensure that patients receive treatments that meet the highest standards of care.

When it comes to safety:     

  • Sirona’s Lu177 Unit Dose Shield is just one way the right products can provide radiation protection from transport to patient administration. The 30 mL syringe for Lu177 radioisotope shield weighs under 8 pounds. 
  • When it comes to packaging and shipping radioactive materials, Sirona’s SWE Type A DOT 7A Packages have interchangeable foam inserts for multiple configurations and DOT certification service for SWE and third party shields within SWE Type A package. 

Medicare Reimbursement: Fueling Innovation

Medicare reimbursement plays a crucial role in driving further development and accessibility of proven theranostic approaches. It provides financial support that encourages healthcare providers and institutions to adopt and continue delivering these cutting-edge treatments. The sustained investment in theranostics, facilitated by Medicare, helps bring these personalized treatments to a wider patient population.
