Brigatinib


Brigatinib is a small-molecule targeted cancer therapy being developed by ARIAD Pharmaceuticals, Inc. Brigatinib acts as both an anaplastic lymphoma kinase and epidermal growth factor receptor inhibitor.
Brigatinib could overcome resistance to osimertinib conferred by the EGFR C797S mutation if it is combined with an anti-EGFR antibody such as cetuximab or panitumumab.

Mechanism of action

Brigatinib is an inhibitor of ALK and mutated EGFR.
ALK was first identified as a chromosomal rearrangement in anaplastic large cell lymphoma. Genetic studies indicate that abnormal expression of ALK is a key driver of certain types of non-small cell lung cancer and neuroblastomas, as well as ALCL. Since ALK is generally not expressed in normal adult tissues, it represents a highly promising molecular target for cancer therapy.
Epidermal growth factor receptor is another validated target in NSCLC. Additionally, the T790M “gatekeeper” mutation is linked in approximately 50 percent of patients who grow resistant to first-generation EGFR inhibitors. While second-generation EGFR inhibitors are in development, clinical efficacy has been limited due to toxicity thought to be associated with inhibiting the native EGFR. A therapy designed to target EGFR, the T790M mutation but avoiding inhibition of native EGFR is another promising molecular target for cancer therapy.

History

Regulatory approval

Ariad Pharmaceuticals, Inc. filed an investigational new drug application to the US FDA on August 29, 2016.
In 2016, brigatinib was granted orphan drug status by the FDA for treatment of NSCLC.
In 28 April 2017, it was granted an Accelerated Approval from the US FDA for metastatic non-small cell lung cancer ; as a 2nd-line therapy for ALK-positive NSCLC.

Intellectual property

On 22 April 2015 ARIAD Pharmaceuticals, Inc. announced the issuance of its first U.S. patent on brigatinib, the protection is through December 30, 2030. The United States Patent and Trademark Office granted U.S. Patent No. 9,012,462 under the title, “Phosphorous Derivatives as Kinase Inhibitors.”

Commercialization

Brigatinib is manufactured by ARIAD Pharmaceuticals, Inc. which is focused on rare cancers. ARIAD then was acquired by Takeda Pharmaceutical Company Limited in February 2017 through a tender offer and subsequent merger of ARIAD with Kiku Merger Co., Inc., a wholly owned subsidiary of Takeda Pharmaceuticals U.S.A. ARIAD is now an indirect wholly owned subsidiary of Takeda.

Names

Brigatinib is the INN.
In Bangladesh it is under the trade name Briganix.
