Every 1-2 weeks for the first month, then every 4-6 weeks until 1 year from the start of therapy, then every 3 months (±1 month) until 2 years, then every 4-6 months (±1 month) after that, blood (about 3-4 teaspoons) will be drawn for routine tests. If the study doctor approves it, you may have these weekly blood draws at a local lab closer to your home. The results from these routine tests will be sent to the study doctor.
