ADC Safety: What You Need to Know About Antibody-Drug Conjugates

When it comes to modern cancer treatment, antibody-drug conjugates, a type of targeted cancer therapy that delivers chemotherapy directly to tumor cells using antibodies. Also known as ADCs, they’re designed to kill cancer cells while sparing healthy tissue—making them one of the biggest advances in oncology in the last decade. But like any powerful tool, they come with risks. ADC safety, the set of protocols, monitoring practices, and risk controls used to manage side effects and ensure patient safety during treatment isn’t just a checklist—it’s a daily reality for patients and doctors alike.

These drugs combine three parts: an antibody that finds cancer cells, a linker that holds everything together, and a potent toxin that kills the cell once inside. Sounds smart, right? But the linker can break too early, spilling the poison into your bloodstream. That’s why chemotherapy side effects, the unintended harm to healthy cells caused by cancer drugs still happen—just differently than with old-school chemo. Instead of nausea and hair loss being the main issue, you might see eye problems, nerve damage, or low blood counts. Some ADCs have caused serious lung inflammation or liver injury in clinical use. The FDA has issued warnings for several, and doctors now monitor blood tests, vision, and breathing more closely than ever before.

Not all patients react the same way. Age, liver function, and what other drugs you’re taking all play a role. If you’re on an ADC, your team will track your blood counts weekly, check your eyes every few weeks, and ask about numbness or tingling in your hands and feet. Skipping a dose because you’re tired? That’s not always the right move. Sometimes, delaying treatment lets your body recover enough to keep going safely. And if you’re also taking something like a blood thinner or a strong antibiotic, those interactions can change how your body handles the ADC. That’s why knowing your full medication list matters as much as the diagnosis itself.

Below, you’ll find real-world guides on how these drugs are used, what goes wrong, and how to stay safe. From managing side effects to understanding how they compare to traditional chemo, the articles here give you the practical details you won’t get from a pamphlet. This isn’t theory—it’s what patients and doctors are dealing with right now.
