Continued Treatment

Experimental group

Description:

Subjects who have completed the required study observation period or are still on treatment upon the closure of their respective BXQ-350 clinical study, and who are judged by the Investigator to benefit from continued treatment with BXQ-350. Treatment will begin after completion of the End of Study visit of the prior BXQ-350 clinical study. The established safe dose of BXQ-350 from previous adult and pediatric phase 1 studies is 2.4 mg/kg and 3.2 mg/kg respectively once every 28 days (± 3 days). BXQ-350 will be administered intravenously at the same dose level and frequency the subject was receiving at the end of the prior BXQ-350 clinical study. Subjects receiving a reduced dose at the end of the prior BXQ-350 clinical study due to toxicity may continue to receive a reduced dose.
