- BACKGROUND: In the two European Union (EU)-funded projects, PCM4EU (Personalized Cancer Medicine for all EU citizens) and PRIME-ROSE (Precision Cancer Medicine Repurposing System Using Pragmatic Clinical Trials), we aim to facilitate implementation of precision cancer medicine (PCM) in Europe by leveraging the experience from ongoing national initiatives that have already been particularly successful. PATIENTS AND METHODS: PCM4EU and PRIME-ROSE gather 17 and 24 partners, respectively, from 19 European countries. The projects are based on a network of Drug Rediscovery Protocol (DRUP)-like clinical trials that are currently ongoing or soon to start in 11 different countries, and with more trials expected to be established soon. The main aims of both the projects are to improve implementation pathways from molecular diagnostics to treatment, and reimbursement of diagnostics and tumour-tailored therapies to provide examples of best practices for PCM in Europe. RESULTS: PCM4EU and PRIME-ROSE were launched in January and July 2023, respectively. Educational materials, including a podcast series, are already available from the PCM4EU website (http://www.pcm4eu.eu). The first reports, including an overview of requirements for the reimbursement systems in participating countries and a guide on patient involvement, are expected to be published in 2024. CONCLUSION: European collaboration can facilitate the implementation of PCM and thereby provide affordable and equitable access to precision diagnostics and matched therapies for more patients. ble from the PCM4EU website (http://www.pcm4eu.eu).

- Overexpression of forkhead transcription factor FOXC2 in white adipose tissue (WAT) leads to a lean phenotype resistant to diet-induced obesity. This is due, in part, to enhanced catecholamine-induced cAMP-PKA signaling in FOXC2 transgenic mice. Here we show that rolipram treatment of adipocytes from FOXC2 transgenic mice did not increase isoproterenol-induced cAMP accumulation to the same extent as in wild type cells. Accordingly, phosphodiesterase-4 (PDE4) activity was reduced by 75% and PDE4A5 protein expression reduced by 30-50% in FOXC2 transgenic WAT compared to wild type. Thus, reduced PDE4 activity in adipocytes from FOXC2 transgenic mice contributes to amplified beta-AR induced cAMP responses observed in these cells.

- Adaptation to the environment and extraction of energy are essential for survival. Some species have found niches and specialized in using a particular source of energy, whereas others-including humans and several other mammals-have developed a high degree of flexibility1. A lot is known about the general metabolic fates of different substrates but we still lack a detailed mechanistic understanding of how cells adapt in their use of basic nutrients2. Here we show that the closely related fasting/starvation-induced forkhead transcription factors FOXK1 and FOXK2 induce aerobic glycolysis by upregulating the enzymatic machinery required for this (for example, hexokinase-2, phosphofructokinase, pyruvate kinase, and lactate dehydrogenase), while at the same time suppressing further oxidation of pyruvate in the mitochondria by increasing the activity of pyruvate dehydrogenase kinases 1 and 4. Together with suppression of the catalytic subunit of pyruvate dehydrogenase phosphatase 1 this leads to increased phosphorylation of the E1α regulatory subunit of the pyruvate dehydrogenase complex, which in turn inhibits further oxidation of pyruvate in the mitochondria-instead, pyruvate is reduced to lactate. Suppression of FOXK1 and FOXK2 induce the opposite phenotype. Both in vitro and in vivo experiments, including studies of primary human cells, show how FOXK1 and/or FOXK2 are likely to act as important regulators that reprogram cellular metabolism to induce aerobic glycolysis.

Konferensbidrag (refereegranskat)abstract
- Background: Over the last decades, there has been a surge in the development and approval of targeted drugs and immunotherapies for treating cancer patients, as seen by the 757 % increase in approvals by the FDA for new cancer treatments since 2000 (1). This has significantly impacted cancer care and contributed to improving overall survival in various cancer subgroups. However, access to these new treatments is constrained by the market access strategy of the patent-owning company and available knowledge of treatment effects. Only a few treatments have received pan-cancer approval from EMA or FDA, and most drugs receive market authorization per indication. As a result, there is a widening access gap between patients with different cancer types (2). Methods: Exploring the effect of biomarker-driven treatments in new cancer subtypes requires the ability to find patients with rare biomarkers. PRIME-ROSE is a European precision medicine network comprising 11 ongoing or soon-to-start national DRUP-like clinical trials testing registered drugs outside their current label (www.prime-rose.eu). Patients with relevant tumor biomarkers are identified and treated with matched drugs available in each trial’s drug portfolio. The ambition is to swiftly and systematically evaluate the effectiveness of approved precision cancer medicines in new indications through pragmatic trial designs and with RWE control cohorts, ensuring expansion into all relevant patient groups to maximize societal benefit. This is particularly relevant for rare cancers, which are enriched in precision medicine trials (3). Results: In PRIME-ROSE, the trials now share and aggregate data to build evidence faster and more effectively impact patient care by addressing key challenges in precision cancer medicine implementation (increasing the recruitment area to 71 million inhabitants). This will significantly reduce the time for filling treatment cohorts and contribute to closing the indication/drug-specific knowledge gap. In fact, several pharmaceutical companies have already shown their interest in and commitment to participating in PRIME-ROSE, as it offers the unique advantage of entering the trials in the network simultaneously (single point of entry) and with a floating allocation of treatment slots between trials, increasing efficiency in finding patients with specific biomarkers to fill treatment cohorts. Conclusions: A unified entry point to the PRIME-ROSE network is feasible and can facilitate building the knowledge base faster for label expansion and/or country-specific approvals/ reimbursement. National multi-stakeholder ecosystems that include pragmatic, RWE-controlled DRUP-like clinical trials may advance precision medicine implementation.
