How it works (mechanism of action)

Folotyn is an antifolate chemotherapy agent:

• It blocks the enzyme dihydrofolate reductase (DHFR) and related folate pathways
• This prevents cancer cells from making DNA and RNA
• As a result, rapidly dividing lymphoma cells are damaged or destroyed

---

How it is given

• Administered as an intravenous (IV) injection
• Given in cycles (commonly once weekly for several weeks, followed by a rest period)
• Patients are often prescribed:
  • Folic acid
  • Vitamin B12
    to reduce side effects
