The London Clinic is actively involved in ethically approved medical research to improve standards of healthcare for our patients and across the industry. 


With one in five people ending up in an intensive care unit at some stage of their lives, The London Clinic proudly sponsored and provided clinical testing for the Xtreme Everest and Xtreme Everest 2 expeditions.

These studies, in conjunction with University College London Hospital, are investigating people’s ability to adapt to low levels of oxygen at high altitude, to develop treatments that will benefit critically ill people in intensive care.


Expeditions travelled up 5,364 metres to Everest base camp and consisted of doctors, researchers and trekkers (including children and identical twins).  The research will provide critical insights into how intensive care patients might be helped in the future. It could help to save hundreds of thousands of lives of people with a range of diseases including cancer, diabetes, heart and lung disease, cystic fibrosis and congenital heart disease.


Our Ethics Committee has granted approval of a significant number of current clinical trials involving Clinic patients or their records in areas such as leukaemia and prostate cancer. 

All trials must meet the rigorous criteria set by the Ethics Committee, which includes ensuring that appropriate patient information and consent is in place, in accordance with relevant General Medical Council (GMC) guidelines.
