Amgen – Amgen : BiTE® 101 | MarketScreener
Most cancers remedies have historically match into one among three classes: chemotherapy, surgical procedure or radiation. In recent times, new approaches and progressive modalities – equivalent to immuno-oncology or therapies focusing on particular genetic mutations – have began to reshape how oncologists take into consideration treating many cancers.
Amgen has been serving most cancers sufferers for practically 30 years, and in that point has turn out to be a frontrunner within the growth of progressive most cancers therapies. Many most cancers sufferers proceed to face vital unmet wants, and Amgen is working to ship new therapies to boost outcomes for sufferers with hard-to-treat cancers. One thrilling space of innovation is the potential for Amgen’s Bispecific T-cell Engager (BiTE®) platform to interact the physique’s immune system in opposition to many various phases and kinds of cancers.
Here is a have a look at essential details about the BiTE platform, together with what it’s and the way it’s designed to work.
What’s BiTE know-how?
BiTE molecules could be designed to interact the physique’s immune system in opposition to particular targets present in some cancers. BiTE know-how is a novel strategy that may be tailored in opposition to a spread of targets, and Amgen is presently investigating the platform’s purposes in various blood cancers and stable tumors.
Amgen’s unique BiTE molecules are comparatively small proteins designed to clear the physique with a typical half-life of some hours, requiring steady IV infusion of the drugs and repeat administration. Amgen has additionally developed half-life prolonged (HLE) BiTE molecules, that are bigger, take longer to clear from the physique, and are presently underneath investigation to evaluate less-frequent dosing schedules for sufferers.
How does BiTE work?
An individual’s immune system contains T cells that search and destroy overseas invaders known as antigens. Not like viruses or micro organism that come from the surface world, cancers are mutations of the physique’s personal cells, and these malignant cells can disguise themselves from the immune system. BiTE molecules are engineered mixtures of two completely different antibody fragments – one facet connects to T cells, whereas the opposite facet could be designed to interact with a tumor-associated antigen.
‘BiTE molecules are designed to behave like a pair of spectacles to assist the immune system see and have interaction with a goal on the floor of the most cancers cells,’ says Greg Friberg, Amgen’s vice chairman and head of worldwide growth for the hematology/oncology therapeutic space. ‘Then the opposite facet of the molecule is designed to tug in T cells to assist combat it.’
Who’re potential candidates for BiTE therapies?
The sector of immuno-oncology has seen vital advances for sufferers with sure kinds of cancers, however many extra nonetheless want further therapeutic choices. The BiTE platform may result in new therapeutic pathways for sufferers who lack further therapy choices.
‘Amgen is investigating dozens of BiTE molecules throughout each stable and hematological malignancies,’ says Peter Kufer, vice chairman and innovator of BiTE Know-how at Amgen. ‘This features a DLL3-targeted BiTE molecule in small-cell lung most cancers, a BCMA-targeted BiTE molecule in a number of myeloma, a PSMA focused BiTE molecule in prostate most cancers, and CD33 and FLT3-targeted BiTE molecules in acute myeloid leukemia.’
Why are improvements like BiTE know-how so essential?
One key advantage of the BiTE platform is its versatility. This potential to adapt BiTE molecules for a spread of various varieties and phases of cancers may have far-reaching purposes. ‘Researchers are investigating these molecules in sufferers with excessive and low tumor burden throughout completely different age teams, in these with quickly progressing illness and throughout completely different therapy strains,’ Kufer says.
One other key profit is that BiTE molecules are being designed with the aim of resulting in off-the-shelf therapies, with out the necessity to manipulate a person affected person’s T cells exterior the physique, as is presently the case with different cell-based immunotherapies. The event of BiTE therapies due to this fact has the potential to assist develop the provision, and accessibility, of immuno-oncology for most cancers sufferers who presently face vital unmet wants.
‘I joined Amgen to assist carry transformational medicines to most cancers sufferers,’ says PK Morrow, Amgen’s vice chairman and world therapeutic space head of Hematology. ‘Amgen’s pipeline has by no means been as broad when it comes to targets and ailments that we’re focusing on, spanning from small molecules to BiTE molecules and past.’
