FDA approves Pfizer's Lorbrena treatment for certain lung cancer patients

Lorbrena, known chemically as lorlatinib, received an accelerated approval, Pfizer said. Its continued approval may depend on verification of clinical benefit in a confirmatory trial.

New Delhi: Pfizer Inc has recently announced the U.S. Food and Drug Administration has approved its lung-cancer treatment for patients with a specific gene mutation who had been previously treated for an aggressive form of the disease.

The treatment, Lorbrena, is designed to treat advanced non-small cell lung cancer in patients with a mutation of the ALK gene, who have relapsed after being treated with ALK inhibitors, such as Pfizer's Xalkori.

While many patients respond to initial ALK inhibitor therapy, they typically eventually experience disease progression and are faced with limited options due to resistance to existing treatments.

Non-small cell lung cancer (NSCLC) accounts for about 85 per cent of lung cancer cases and remains difficult to treat. About 3 to 5 per cent of NSCLC tumours are ALK-positive and is often found in non-smokers.

Lorbrena, known chemically as lorlatinib, received an accelerated approval, Pfizer said. Its continued approval may depend on verification of clinical benefit in a confirmatory trial.
