SHERLOCK will examine whether sotorasib used in first line treatment of advanced KRAS G12C+ NSCLC, in combination with two chemotherapy drugs (called carboplatin and pemetrexed) and bevacizumab (which improves anti-cancer drug delivery) improves the response of the tumour to treatment. Sotorasib is available on the PBS as monotherapy in 2nd or later lines of treatment. Patients with advanced KRAS G12C+ NSCLC usually undergo initial treatment with chemotherapy, immunotherapy or a combination of the two treatments.
