How long does it take for osimertinib/osimertinib to take effect?

Osimertinib/Osimertinib The time to effect varies based on individual differences and disease characteristics, but a certain degree of efficacy can usually be observed within a few weeks of starting treatment. For some patients, they may begin to experience a reduction in symptoms or stabilization of the disease early in treatment, such as reduced dyspnea, reduced cough, etc. However, in other patients, it may take longer to see significant effects. Generally speaking, osimertinib usually requires several months after the start of treatment to achieve its maximum efficacy, such as prolonging progression-free survival and overall survival.
