Organoids cultured from patient-derived colorectal cancer cells have been used to demonstrate for the first time that tumors which have developed resistance to the full range of existing treatments, across chemotherapies, targeted therapies and immunotherapies, retain a requirement for Werner helicase (WRN) for survival. WRN has a key role in the maintenance of genome stability, but although loss of WRN is known to initiate synthetic lethality in DNA mismatch repair deficient colorectal cancer, studies into the effect of inhibiting that helicase have to date been limited to a handful of cell lines.

DUBLIN – The Biden administration’s proposals on global corporation tax reform have set alarm bells ringing across the Irish government, as officials digest the possible implications of the plan for Ireland's foreign direct investment model of economic development.

DUBLIN – A newly published retrospective analysis of the electronic health care records of more than 500,000 COVID-19 patients has found that infection with SARS-CoV-2 carries “a significantly and substantially” greater risk of cerebral venous thrombosis (CVT) than does either one of the two approved mRNA COVID-19 vaccines or infection with influenza virus.

PARIS – Roche SAS, the French division of Swiss pharmaceuticals manufacturer Roche Holding AG, has signed a partnership with Unicancer that brings together all the cancer centers in France. They have created Oncodatahub (ODH), the first real-world cancer data platform in France. This makes a set of quality, longitudinal data representative of cancer patient care in France available to all those involved in the health care ecosystem.

LONDON – The U.K. is moving on to the next phase of testing mixed dosing schedules for COVID-19 vaccines, launching a study in which it will assess the effect of using Moderna Inc. or Novavax Inc.’s products as the second dose in a heterologous prime boost trial.

LONDON – A large scale prospective study has shown that increased blood plasma viscosity is correlated with disease severity and the likelihood of progression to organ failure, in patients who are hospitalized with COVID-19 infections. Researchers at Addenbrooke’s Hospital in Cambridge, U.K. suggest this could be an easy but sensitive way to quickly triage patients admitted to hospital with symptoms of COVID-19.

A threat is currently hanging over the Swiss medical device industry, which is heavily reliant on trade with the EU. Upcoming changes to the CE marking regime will have the effect of making the mutual recognition agreement (MRA) obsolete. This currently allows Switzerland to enjoy unrestricted access to the medical device market in the 27 member states. Up until now, this bilateral agreement has regulated trade between Switzerland and the EU.

LONDON – The EMA has concluded that the rare cases of serious blood clots with low platelet counts seen after administration of Astrazeneca plc’s COVID-19 vaccine are caused by the vaccine, but said the benefits of its use continue to outweigh the risks. The possibility of cerebral venous sinus thrombosis and splanchnic vein thrombosis in the abdomen will now be listed as rare side effects and the EMA’s guidance to health care professionals will be updated.

HONG KONG – SK Biopharmaceuticals Co. Ltd. partner Arvelle Therapeutics GmbH, now part of Angelini Pharma, has received European Commission (EC) approval for Ontozry (cenobamate), a treatment for drug-resistant focal-onset seizures. The approval was granted for focal-onset seizures with or without secondary generalization in adults who have not been adequately controlled despite a history of treatment with at least two anti-epileptic medicines.

The European Commission opened a public consultation to help it develop the Health Emergency Preparedness and Response Authority, a new initiative to better prepare Europe for cross-border health threats.
