<\/a><\/p>\nChemotherapy is used to treat many kinds of cancer and works by disrupting the way cancer cells grow and divide.<\/p>\n
However, in some patients it is not as effective as it should be because the body\u2019s own immune cells can act as a barrier around tumours.<\/p>\n
These white blood cells, known as macrophages, produce a protein called heme oxygenase-1 (HO-1), which helps shield the tumour from the immune system and block the effects of chemotherapy.<\/p>\n
KCL-HO-1i, which has been created by experts at Kings College London (KCL), targets this protein to make tumours more responsive to treatment.<\/p>\n
Professor James Arnold, head of tumour immunology group at the university, said: \u201cWe discovered that these macrophages in cancer play a key role in blocking chemotherapy.<\/p>\n
\u201cBy targeting the enzyme they produce using KCL-HO-1i, we were able to help beneficial immune cells and chemotherapy drugs become significantly more effective.<\/p>\n
\u201cIn laboratory models, even chemotherapy-resistant tumours became responsive to treatment, which is a really exciting step forward.\u201d<\/p>\n
The drug has been designed for patients to take at home as a tablet between chemotherapy sessions.<\/p>\n
Early tests on mice, published in the journal Science Translational Medicine, found the drug made breast cancer tumours more responsive to different types of chemotherapy.<\/p>\n
Researchers are now hopeful that trials involving patients with breast cancer and other forms of the disease could begin within two years.<\/p>\n
James Spicer, a professor of experimental cancer medicine at KCL, said: \u201cChemotherapy remains a key part of treatment for many patients with cancer, but too often it is not as effective or long-lasting as we might like.<\/p>\n
\u201cThis research has identified a key reason for these limitations, and discovered a drug that we are keen to test in the clinic alongside established chemotherapy drugs.\u201d<\/p>\n
Miraz Rahman, a professor of medicinal chemistry at KCL, added: \u201cIf human trials are successful, KCL-HO-1i could become a valuable companion drug to existing cancer therapies \u2013 helping more patients to benefit from the treatments that are already available and reduce the need for more aggressive cancer therapies in the future.\u201d<\/p>\n
The King\u2019s College London scientists have launched a spin-out company called Aethox Therapeutics.<\/p>\n
Tanya Hollands, research information manager at Cancer Research UK, which supported the study alongside funding from the Medical Research Council, said: \u201cResearchers are increasingly learning how to make better use of existing cancer treatments, whether it\u2019s using them differently or in combination with new medicines, like this work suggests.<\/p>\n
\u201cUsing combination therapies can help bring improved treatment options to patients more quickly, safely and affordably, because some components of the treatment have already been tested and used in the clinic.<\/p>\n
\u201cWhile early stage, it\u2019s exciting to see this potential new way to disarm cancer\u2019s ability to avoid detection by the immune system with a new drug, while also boosting the effectiveness of chemotherapy, and we look forward to seeing how this work progresses.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"A take-at-home tablet could boost the way cancer patients respond to chemotherapy, according to the medical experts who…\n","protected":false},"author":2,"featured_media":60151,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[39466,49,48,7714,18356,28867,84,10236,2974,66,3585],"class_list":["post-60150","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-aethox-therapeutics","tag-ca","tag-canada","tag-cancer","tag-cancer-treatment","tag-chemotherapy","tag-health","tag-kings-college-london","tag-pharmaceuticals","tag-science","tag-uk"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/60150","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=60150"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/60150\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/60151"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=60150"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=60150"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=60150"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
