During Cycle 2 of therapy, if you have not experienced any intolerable side effects, you will be given temozolomide. You will receive temozolomide by mouth once a day, for 5 days in a row, during the first week of each cycle. You will also continue to receive the L9-NC aerosol over about 30 minutes once a day, for 5 days in a row, for 2 weeks. Doctors will then monitor you for safety for another 2 weeks after treatment.
