GSK Belantamab Mafodotin shows to help blood cancer patients

Two doses of Belantamab Mafodotin helped subdue the disease in adults who had received three prior treatments for multiple myeloma, a cancer of the white blood cells, GSK said.

New Delhi: GlaxoSmithKline said its experimental multiple myeloma treatment showed a meaningful response in patients that have run out of three previous treatment options, in a boost for the British drugmaker's cancer drug business.

Two doses of Belantamab Mafodotin helped subdue the disease in adults who had received three prior treatments for multiple myeloma, a cancer of the white blood cells, GSK said on Friday, adding that it intends to seek market approval and submit data from the trial to regulatory bodies this year.

GSK sold its approved oncology drugs to Novartis in 2014 but has staged a comeback bid in cancer with a deal to buy U.S. firm Tesaro for $5.1 billion last year and an agreement to pay up to 3.7 billion euros to Germany's Merck KGaA for the rights to next-generation immunotherapy in February.

"We are on track to file Belantamab Mafodotin later this year and continue to investigate how it could help even more patients with this disease," Chief Scientific Officer Hal Barron said.

Belantamab Mafodotin targets a protein linked to multiple myeloma known as BCMA.
