    Abstract:
    9-beta-D-Arabinofuranosyl-2-fluoroadenine 5'-monophosphate (NSC 312887) is a new purine antimetabolite that has been evaluated in a Phase I clinical trial. The schedule of administration consisted of a single i.v. infusion over a period of 30 min once each day for 5 consecutive days, repeated at 4-week intervals. Thirteen patients received 30 courses of the drug in a dose range of 18 to 40 mg/sq m/day. Granulocytopenia and thrombocytopenia were dose limiting. Repeated courses produced similar degrees of granulocytopenia, but in 7 of 7 patients receiving 2 or more courses, the degree of thrombocytopenia was less severe during the first than during subsequent courses. Myelosuppression in humans was more severe than predicted from the mouse model. Lymphopenia was profound at all dose levels, but reversed within 3 weeks. Somnolence occurred during infusion in 8 of 13 patients, but quickly cleared after the infusion was completed. The infused drug was rapidly dephosphorylated in plasma and then cleared so there was no cumulation of drug in plasma when it was rapidly infused once each day in these doses. Phase II studies of 9-beta-D-arabinofuranosyl-2-fluoroadenine 5'-monophosphate are planned at a starting dose of 18 mg/ sq m/day for patients with prior chemotherapy or radiotherapy and 25 mg/sq m/day for those without prior therapy, as a single dose on each of 5 consecutive days repeated at 21- to 28-day intervals.
