Study Overview

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

This is a multicenter, open label, Phase 1 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 or subcutaneously 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 RP2D is determined from either the intradermal or subcutaneous group, an additional 40 patients evaluable for response 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 RP2D expansion cohort described previously, and once the intradermal dose-ascending cohort is completed, up to 20 MDS patients who are refractory 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; [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 (MDS Cohort 2).

Primary Outcome MeasuresMeasure DescriptionTime Frame
Determination of the safety and tolerability of DSP-7888 Dosing Emulsion by assessing dose-limiting toxicities (DLTs)4 weeks
Determination of the safety and tolerability of DSP-7888 Dosing Emulsion by assessing duration of study treatment12 months
Determination of the Recommended Phase 2 Dose (RP2D) by assessing dose-limiting toxicities (DLTs)4 weeks
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Assessment of the preliminary anti-tumor activity by assessing Progression-Free Survival (solid tumors and acute myeloid leukemia (AML))Evaluation of anti-tumor activity will be performed according to Immune Related Response Criteria (irRC) for solid tumors. For patients with ovarian cancer who have disease at baseline that is evaluable by CA-125 criteria only, the Gynecologic Cancer Intergroup (GCIG) criteria will be used for response assessment. For patients with AML, response assessment will be performed according to the AML International Working Group (IWG) criteria.12 months
Overall Survival12 months
Pharmacodynamic activity of DSP-7888 Dosing Emulsion as assessed by biomarker analysisCytotoxic T lymphocyte induction, histopathology and Reverse transcription polymerase chain reaction (RT-PCR) assays will be performed to provide information of the biomarkers on biopsied patient tumor tissue, archival samples and peripheral blood samples.12 months
