A Study of DSP-7888 Dosing Emulsion in Adult Patients With Advanced Malignancies

Basic Study Information

Purpose:
This is a dose-escalation study of DSP-7888 Dosing Emulsion administered to adult patients with advanced malignancies. Patients will be administered escalating doses of DSP-7888 Dosing Emulsion intradermally (between the skin layers) or subcutaneously (under the skin) in accordance with the following regimen: once weekly for four weeks during the Induction Phase, once every 7 to 14 days for 6 weeks during the Consolidation Phase, and once every 14 to 28 days until a discontinuation criterion is met during the Maintenance Phase. Once the highest dose with acceptable toxicity is determined from either the intradermal or subcutaneous group, an additional 40 patients may be enrolled as an expansion cohort at this dose and route of administration to confirm safety and tolerability. Separate from the dose-ascending cohort and expansion cohort described previously, and once the intradermal dose-ascending cohort is completed, up to 20 myelodysplastic syndrome (MDS) patients who are resistant to treatment with hypomethylating agents (HMAs) will be enrolled into an MDS expansion cohort. Of these 20 MDS patients, one-half will receive DSP-7888 at 10.5 mg according to the modified schedule employed in Phase 1 (every week for 4 weeks, every 2 weeks until Week 24, and then every 4 weeks [Named MDS Cohort 1]). The other half of the MDS patients will receive DSP-7888 at 10.5 mg in an alternative dosing schedule where DSP-7888 is administered every 2 weeks until Week 24, after which it will be administered every 4 weeks (Named MDS Cohort 2).
