The Medicines and Healthcare products Regulatory Agency (MHRA) has today, 6 March 2025, approved lazertinib (brand name Lazcluze) for adults with non-small cell lung cancer that has spread to other parts of the body and has undergone specific changes in a gene called epidermal growth factor receptor (EGFR). It is to be used in combination with an approved cancer medicine called amivantamab.

Lazertinib works by blocking EGFR and may help to slow or stop the lung cancer from growing. It may also help to reduce the size of the tumour. It is taken daily in tablet form.  

Julian Beach, MHRA Interim Executive Director of Healthcare Quality and Access, said:

Patient safety is our top priority, which is why I am pleased to confirm approval of Lazertinib for the treatment of adults with non-small cell lung cancer. 

We’re confident that the appropriate regulatory standards of safety, quality and effectiveness for the approval of this new formulation have been met. 

As with all products, we will keep its safety under close review.

Lazertinib has been evaluated in a clinical trial, in which a total of 1074 participants were randomised to receive one of three treatments. The lazertinib and amivantamab combination treatment was compared against treatment with lazertinib alone, and against treatment with another cancer medicine osimertinib. Participants who received the combination treatment had a longer period without progression of their disease, as compared to patients who received the other two treatments.  

Like all medicines, this medicine can cause side effects, although not everybody gets them. Some of the most common side effects are skin problems (such as rash, itching and dry skin), decreased appetite, nausea, muscle spasms, vomiting and fever.
