Radiopharmaceuticals require sophisticated infrastructure, with just-in-time radioactives delivered to patients who must isolate while receiving the therapy. Quality control and numerous layers of regulation makes for a daunting space to enter. Although the demand for medical isotopes is growing, the facilities that can make these products are aging, and one of the major facilities globally has already come offline. Next steps for the industry will be to solve supply and regulatory challenges as clinical trial data start to differentiate therapies in the pipeline.
The possibilities of cures for cancer and other tough-to-treat diseases and the ability to further personalize medicine are creating a lot of excitement about the future of radiopharmaceuticals as both therapy and diagnostics. To reach that future, industry and researchers will have to overcome a lot of challenges, not the least of which stem from the multiple government agencies involved in regulating the source material, development, distribution and use of radioactive drugs and devices.
The radiopharma field has garnered increasing attention in recent years due to big-ticket deals like Bayer AG's $2.9 billion acquisition of Algeta ASA and Novartis AG's nearly $6 billion spent on buying Advanced Accelerator Applications SA and Endocyte Inc. As a result, competition is ratcheting up and pipelines are exploding with new combinations of different drugs. The global radiopharmaceuticals market was estimated to be valued at $6.7 billion in 2020, a number expected to reach $11.5 billion by 2027, according to a 2022 William Blair report.
Global interest in radiopharmaceuticals is growing, and some big deals in the space have sparked interest in the last few years. Novartis AG has spent about $6 billion in acquisitions and is seen as the global leader.
To help drug manufacturers comply with the technical requirements of RCD 753/2022 and other related standards regarding proof of a drug’s safety and efficacy, Brazil’s Anvisa issued three new guidelines for submitting registration requests for new or innovative synthetic and semi-synthetic drugs.
The big idea behind radiopharmaceuticals is taking the hallmarks of two cancer therapies – radiology and chemotherapy – and merging them, and this is what makes the technology a disrupter.
If its challenges can be overcome, radioligand therapy is poised to change the way many cancers are treated. It is also likely to become an example of how scientific advances, once they are translated successfully, can enable further insights in a bench-to-bedside-to-bench loop. David Piwnica-Worms, professor and chair of cancer systems imaging at The University of Texas MD Anderson Cancer Center, predicted that as radioligand therapy expands, many questions will be answered about both radiation biology and the interaction of radiation with the immune system more specifically.
After spending decades developing targeted chemotherapy and bringing a dozen or so compounds into the clinic, Fusion Pharmaceuticals Inc. Chief Scientific Officer Christopher Leamon switched careers to focus on radio-oncology because he saw the need for “a really strong bomb to target cancer to get it to respond.” That was radiotherapy, said Leamon, who was one of the scientific founders of Endocyte Inc., which Novartis AG acquired.
Evergreen Discovery (Evergreen Theragnostics Inc.) and Orbit Discovery Ltd. have entered into a collaboration to identify specific cell-targeting peptides and advance the development of novel radiopharmaceuticals.
