The drug, 'durvalumab', can double the overall time someone can survive with an aggressive form of lung cancer from two-and-a-half to five years.
It has been approved by the National Institute for Health and Care Excellence (NICE) and the NHS has sealed a deal with manufacturer AstraZeneca to begin rolling
it out.
The new treatment will be offered to more than 550 patients a year with advanced non-small-cell lung cancer (NSCLC) who have already undergone both chemotherapy
and radiotherapy concurrently.
NHS said: "The drug can stop the cancer from getting worse for more than two years - significantly longer than treatment with a combination of chemotherapy and
radiotherapy, which can only hold the disease at bay for around six months. This increases overall survival time and gives patients more precious moments with their
loved ones."
Dame Cally Palmer, national cancer director for NHS England, said: "We are resolute in our ambition to fight the devastating effects of cancer and new pioneering
treatments like durvalumab are a vital lifeline for people living with cancer - giving them more precious time with family and friends.
'Tepotinib' has been recommended by the National Institute for Health and Care Excellence (NICE) to patients with a specific gene mutation of advanced
non-small-cell lung cancer (NSCLC).
The new potentially life-extending drug is available from Thursday (14 April). It has been recommended for routine use across the NHS in England through Project
Orbis, a programme to review and approve promising cancer drugs helping patients access treatments faster.
NICE has published its final appraisal document recommending tepotinib (also known as Tepmetko and produced by company Merck Serono Ltd) as an option for treating
advanced NSCLC with METex14 skipping gene alterations in adults.
People with METex14 skipping alterations of NSCLC make up between 1-2% of all adults with lung cancer in England.
Tepotinib, which requires people to take two tablets once daily, provides a new targeted treatment for adults with METex14 skipping gene alterations. Just over 700
people in England would be eligible to receive tepotinib as either a first or second-line treatment.
The Association of the British Pharmaceutical Industry (ABPI) has supported the Department of Health and Social Care's recommendation to 'aggressively expedite and roll out new medicines' that have gone through trials.
The ABPI welcomes government report on cancer services in England and the opportunity it provides to refocus how the pharmaceutical industry, NHS and government can improve the lives of cancer patients.
David Watson, executive director, Patient Access at the ABPI, said: "Despite progress, UK patients still have much worse five-year survival rates for many cancers than those in similar nations. Early diagnosis and fast and equal access to the latest treatments for all patients is key to reversing poor trends in NHS cancer care.
"We are pleased that the report reflects concerns about variable access to cancer medicines. We support the Committee's recommendations to 'aggressively expedite
and roll out new medicines' that have gone through trials and to ensure regulatory innovation results in swift uptake in the UK.
