Responses in patients who achieve complete remission can be durable.

Another measure showed slightly better results, with 33 percent achieving remission.

Ninety percent of patients in this study achieved remission after induction therapy.

The remaining two patients did not achieve remission after four weeks of treatment.

And more than a third of those who achieved remission relapsed within a year.

Patients who achieved remission did not experience a spontaneous relapse.

But I am concerned that people may be led to believe that many achieve remission without medication.

In one study, more than half of patients on the combination therapy achieved remission.

However, it can take longer for older people to respond to treatment - on average, it takes 12 weeks to achieve remission.

Approximately 50% to 60% of patients will achieve sustained remission using this treatment approach.
