During Cycle 3 of therapy, if you have not experienced any intolerable side effects, you will continue to be given temozolomide by mouth once a day, for 5 days in a row, during the first week of each cycle. You will receive the L9-NC aerosol twice a day, about 12 hours apart, over about 30 minutes, for 5 days in a row, for 2 weeks. If you experience any bad side effects during Cycle 2, your dose of temozolomide will be decreased, and you will continue to receive L9-NC aerosol once a day (instead of twice a day), for 5 days in a row, for 2 weeks.
