Treatment Cycle
Also known as: Dosing cycle, Treatment schedule, Therapy cycle
Definition
The schedule of when a treatment is given, including the treatment period and rest period.
Detailed Explanation
Treatment cycles vary by drug. For example, Keytruda is typically given every 3 or 6 weeks, OPDIVO every 2 or 4 weeks. A cycle includes the treatment day(s) plus the rest period before the next dose. This schedule is designed to maximize efficacy while allowing the body to recover. Most immunotherapy is continued until disease progression or unacceptable toxicity.
