As a colorectal cancer (CRC) patient, survivor, or loved one of someone diagnosed with cancer, you have had VOCABULARY many discussions with your treatment team about which medicines to take • Shared decision-making and which treatments will be the The process in which doctors most beneficial.

You make both, and both are delicious. A few months later, you decide to make more of each, following the same recipes. For the cookies, you follow each Why did the cookies turn direction precisely; however, out exactly the same and the you use different brands of each beer turned out similar, but not ingredient. Still, you use flour, identical? Largely this is because chocolate chips and all of the other beer is a living, fermenting product, ingredients needed.

The examples of baking cookies and brewing beer are a bit of a The beer is a slightly different stretch, but it's a good way to start story. The temperature of your thinking about generic and brand- house varied from the first brew name drugs (in this case, cookies) to the second brew. You followed and biologics and biosimilars the directions exactly, but the beer (in this case, beer). tasted just a little bit different. It was still delicious and had all the properties expected of beer but the taste was not identical to the first. 3 • FightCRC.org • BACKGROUND: WHAT'S THE DIFFERENCE BETWEEN SMALL MOLECULE VS LARGE MOLECULE?

The term generic drug is applied to small molecular drugs (drugs made from chemical combinations). In manu- facturing them, it’s about chemistry and following a formula. While generics and brand-name drugs follow the same formula, generics can cost up to 80-85% less than their brand-name counterpart. 7 • FightCRC.org • Common questions about brand- name and generics: Q: If they are the same, why do both generic and brand- name drugs exist? A: When a new drug is developed cost clinical trials a new product and clinical trials prove it to be would have to complete to be safe and effective, it goes to the approved by the FDA.
