What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Ayvakit (avapritinib) is a kinase inhibitor indicated for the treatment of adults with unresectable or metastatic gastrointestinal stromal tumors (GIST) harboring a platelet-derived growth factor receptor alpha (PDGFRA) exon 18 mutation, including PDGFRA D842V mutations. It is also approved for the treatment of advanced systemic mastocytosis (AdvSM), including aggressive systemic mastocytosis, systemic mastocytosis with an associated hematologic neoplasm, and mast cell leukemia. Ayvakit selectively inhibits mutated forms of KIT and PDGFRA kinases, which are key drivers of disease progression in these patient populations.

Dose adjustments may be necessary based on tolerability, hepatic impairment, or drug interactions. Treatment should continue until disease progression or unacceptable toxicity occurs. Ayvakit should be prescribed and monitored by physicians experienced in the use of antineoplastic therapies.
