Unlabelled: BACKGROUND AND OBJECTIVES: BI 425809, a novel glycine transporter-1 inhibitor, may ameliorate cognitive deficits in schizophrenia. The objectives of the studies were: to assess absolute bioavailability of oral BI 425809 compared with intravenous (IV) microtracer infusion (study 1), and to determine the mass balance, distribution, metabolism, and excretion of BI 425809 (study 2).
Methods: These were Phase I, open-label, non-randomized, single-period, single-arm studies in healthy males.
BI 836826 is a chimeric immunoglobulin G1 antibody targeting CD37, a tetraspanin transmembrane protein predominantly expressed on normal and malignant B cells. This phase I, open-label study used a modified 3 + 3 design to evaluate the safety, maximum tolerated dose (MTD), pharmacokinetics, and preliminary activity of BI 836826 in patients with relapsed/refractory B cell non-Hodgkin lymphoma (NHL; NCT01403948). Eligible patients received up to three courses comprising an intravenous infusion (starting dose: 1 mg) once weekly for 4 weeks followed by an observation period of 27 (Course 1, 2) or 55 days (Course 3).
