We are a team of PhD students, master students, postdocs and technicians with expertise in chemistry, biochemistry, biology and pharmaceutical sciences working together towards our common goals on diverse projects in the field of radiopharmaceutical sciences as outlined below.

Open all

Radiopharmaceutical sciences is an interdisciplinary field of applied research that combines expertise in physics, (radio)chemistry, (radio)biology, (radio)pharmacy and (nuclear) medicine with the aim to develop and investigate radiopharmaceuticals in view of their clinical application.

The development of radiopharmaceuticals for tumor targeting includes the design, synthesis and radiolabeling of tumor-specific ligands, their preclinical in vitro and in vivo evaluation and – in an ideal case – their clinical translation and application in nuclear medicine/oncology.

Nuclear imaging makes use of radiopharmaceuticals that – based on the employed radionuclide – emit gamma-radiation or positrons for Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET), respectively. The detection of the emitted radiation provides information about (patho)physiological processes on a molecular level and enables diagnosis and staging of a (cancer) diseases.

Targeted radionuclide therapy or endoradiotherapy makes use of radiopharmaceuticals that – based on the employed radionuclide – emit alpha particles, beta minus particles and/or Auger electrons. The specific accumulation of therapeutic radiopharmaceuticals in malignant lesions enables direct irradiation of cancer cells and is, thus, a strategy of particular value for the treatment of metastatic disease.

Nuclear imaging is most often employed for the staging and restaging of cancer diseases before and after therapy. It enables the detection of metastatic disease and demonstrates whether the applied therapy is effective in reducing the tumor burden. The concept of “radiotheragnostics” using target-specific radiopharmaceuticals pursues an additional goal in that the diagnostic image provides information about the expression of a specific therapeutic target which is useful for subsequent application of radionuclide therapy. This concept has been implemented in clinical routine for patients with cancer types that express for example the somatostatin receptor or prostate-specific membrane antigen for which targeted radionuclide therapies exist. In future, radioimaging agents may also serve for the selection of patients with diseases who could profit from other treatment options such as tumor target-specific (immuno)therapies.

Open all

The research of our group is dedicated to the design and evaluation of small-molecular-weight tumor targeting radioligands for theragnostic application, among those are radioconjugates for folate receptor (FR)-targeting as well as for targeting the prostate-specific membrane antigen (PSMA).

Our goal is to optimize the pharmacokinetic profile of the radioligands by various chemical modifications such as the derivatization with albumin-binding entities.

A major interest lies in the application and (radio)biological investigation of different radiation types using non-standard (exotic) radionuclides, which are promising for the development of the theragnostic concept.

In view of a therapeutic application, we are interested in the combination of targeted radionuclide therapy with other cancer treatments (e.g. chemotherapy, immunotherapy).

Research Interests
Open all

The development of radiopharmaceuticals with favorable pharmacokinetics requires the synthesis of compound libraries to gain knowledge about structure-activity relationships, which can subsequently be used for structural optimization. For this reason, our research group established synthetic methods for the fast and easy preparation of a broad range of structurally modified tumor-targeting folate conjugates.

The folate radioconjugates accumulated specifically in folate receptor (FR)-positive tumor tissue, however, a significant amount of activity was retained in the kidneys. A major breakthrough was achieved by the derivatization of folate radioconjugates with an albumin-binding entity. The enhanced blood circulation of these novel class of folate radioconjugates resulted in an increased uptake of activity in the tumor, but reduced retention in the kidneys.

This promising approach was translated also to PSMA-targeted radioligands. It resulted in the development of new PSMA radioligands that show great potential for therapeutic application. Current projects focus on the optimization of the pharmacokinetic properties of these and other tumor targeting agents using different types of albumin binder and linker entities, respectively.

Non-standard (exotic) radionuclides are developed and produced by the Radionuclide Development group (headed by Dr. Nicholas van der Meulen).

Radionuclide Development

The group is particularly interested in radionuclides of the same element (radioisotopes) which allow the preparation of chemically identical radiopharmaceuticals for imaging and therapy, respectively. Scandium comprises three medically interesting radioisotopes: 43Sc and 44Sc are useful for positron emission tomography (PET) and 47Sc is a radioisotope for therapeutic application and single photon emission computed tomography (SPECT). Over the last decade we have been investigating scandium radioisotopes in several preclinical studies.

A large number of pioneering studies have been performed with terbium sister radioisotopes. Terbium is unique as it comprises four radioisotopes for all four modalities in nuclear medicine, including SPECT (155Tb), PET (152Tb), alpha (149Tb) and beta radionuclide therapy (161Tb). Over the last decade, we have performed studies with all four radioisotopes in preclinical settings.

Currently, several preclinical projects are on-going with terbium sister radioisotopes in the group and in collaboration with external partners.

161Tb is the most advanced in terms of production and preclinical investigations. Tumor-cell based in vitro studies, in which the effect of 161Tb-PSMA-617 was compared to that of 177Lu-PSMA-617, demonstrated the advantage of using 161Tb over 177Lu due to the co-emission of a substantial number of conversion and Auger electrons.

Cell viability

Recently, new projects have been initiated with regard to more in-depth studies using other exotic radionuclides such as 175Yb and 165Er.

Over the last years, we have been investigating the radiosensitizing effects of chemotherapeutic agents (e.g.  the antifolate pemetrexed).

Our group investigated the effect of radiation to enhance the tumor response to immunotherapy. In a recently performed preclinical study, our group demonstrated the effect of 177Lu-DOTA-folate as an immune stimulus to enhance anti-CTLA-4 immunotherapy in a syngeneic breast tumor mouse model.

18F-AzaFol, a PET agent for imaging folate receptor-positive tumors, was investigated in a multicenter clinical trial at three hospitals in Switzerland (NCT03242993).

Several projects are on-going with regard to first-in-man applications of novel PSMA-targeting radioligands and for the investigation of non-standard radionuclides.

The application of 152Tb-PSMA-617 for imaging of prostate-specific membrane antigen (PSMA)-positive prostate cancer, was demonstrated in a patient with metastatic castration-resistant prostate cancer (mCRPC) at Zentralklinik, Bad Berka, Germany.
