Alecensa

Alectinib (INN, marketed as Alecensa) is an oral drug that blocks the activity of anaplastic lymphoma kinase (ALK) and is used to treat non-small-cell lung cancer (NSCLC). It was developed by Chugai Pharmaceutical Co. Japan, which is part of the Hoffmann-La Roche group.

History, clinical trials, Approvals and medical uses

Alectinib was approved in Japan in July 2014 for the treatment of ALK fusion-gene positive, unresectable, advanced or recurrent non-small-cell lung cancer (NSCLC).

It was granted an accelerated approval by the US Food and Drug Administration (FDA) in December 2015 to treat patients with advanced ALK-positive NSCLC whose disease worsened after, or who could not tolerate, treatment with crizotinib (Xalkori). (This was converted into a full approval in Nov 2017).

It got a conditional approval by the European Medicines Agency in February 2017 for the same indication. This means that additional studies are awaited to confirm a positive benefit-risk-ratio.

The approvals were based mainly on two trials: In a Japanese Phase I–II trial, after approximately 2 years, 19.6% of patients had achieved a complete response, and the 2-year progression-free survival rate was 76%. In February 2016 the J-ALEX phase III study comparing alectinib with crizotinib was terminated early because an interim analysis showed that progression-free survival was longer with alectinib.

In November 2017 the FDA approved alectinib for the first-line treatment of patients with ALK-positive metastatic non-small cell lung cancer.bThis based on the phase 3 ALEX trial comparing it with crizotinib.
