Brief Summary:

This will be a Phase 1, open-label study of DS-3032b to assess its safety and tolerability, identify a maximum tolerated dose (MTD)/tentative recommended phase 2 dose (RP2D), and assess its pharmacokinetic (PK)/ pharmacodynamic (PD) properties in subjects with advanced solid tumors or lymphomas.

Approximately 5 US sites are planned for Part 1 (Dose Escalation). Approximately 10 US sites are planned for Part 2 (Dose Expansion).

Primary Outcome Measures :
  1. maximum tolerated dose [ Time Frame: 28 days ]
    To determine the maximum tolerated dose (MTD) or tentative recommended Phase 2 dose (RP2D) of DS-3032b in subjects with advanced solid tumors or lymphomas.

  2. tumor response [ Time Frame: 8 weeks ]
    To assess tumor response in subjects with melanoma using Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 and in subjects with diffuse large B-cell lymphoma (DLBCL) using the revised International Working Group (IWG) criteria.

Secondary Outcome Measures :
  1. plasma pharmacokinetics [ Time Frame: 28 days ]
    To determine the plasma pharmacokinetics (PK) of DS-3032a (the free form of DS-3032b).

  2. effect on macrophage inhibitory cytokine-1 levels [ Time Frame: day 28 ]
    To determine the pharmacodynamic (PDy) effect of DS-3032b on macrophage inhibitory cytokine-1 (MIC-1) levels in serum.

  3. determine relationship between tumor response and biomarker p53 [ Time Frame: day 8 ]
    To evaluate the relationship between tumor response to DS-3032b and predictive biomarkers (e.g. p53, p21, p14, p16, MDM2, MDM4) studied in archived tumor samples and pre treatment tumor biopsies.

  4. Determine PK profile of DS-3032a at the MTD/tentative RP2D [ Time Frame: day 28 ]
    To determine the PK profile of DS-3032a at the MTD/tentative RP2D.

  5. Determine the PD effect of DS-3032b on MIC-1 levels in serum [ Time Frame: day 28 ]
    To determine the PD effect of DS-3032b on MIC-1 levels in serum.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Has a histologically or cytologically documented advanced solid tumor or lymphoma that has relapsed from or is refractory to standard treatment, or for which no standard treatment is available. Subjects with melanoma who are ineligible to receive or have declined ipilimumab treatment, or who are refractory or intolerant to ipilimumab may enroll.
  • Man or woman >= 18 years old.
  • Has an Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
  • Has adequate bone marrow function, defined as:

Platelet count >= 100 x 109/L Hemoglobin >= 9.0 g/dL Absolute neutrophil count >= 1.5 x 109/L.

- Has adequate renal function, defined as: Creatinine clearance >= 60 mL/min, as calculated using the modified Cockcroft Gault equation, ([{140 - age in years} × {actual weight in kg}] divided by [{72 × serum creatinine in mg/dL} multiply by 0.85 if female]), OR creatinine =< 1.5 x ULN.

- Has adequate hepatic function, defined as: AST/ALT levels =< 3 x ULN (if liver metastases are present, =< 5 x ULN) Bilirubin =< 1.5 x ULN.

- Has adequate blood clotting function, defined as: International normalized ratio (INR) and activated partial thromboplastin time (aPTT) =< 1.5 x ULN.

  • Subject should be able to provide written informed consent, comply with protocol visits and procedures, be able to take oral medication, and not have any active infection or comorbidity that would interfere with therapy.
  • Subject (male and female) of childbearing/reproductive potential must agree to use double-barrier contraceptive measures or avoid intercourse during the study and for 90 days after the last dose of study drug.
  • Subject must be fully informed about their illness and the investigational nature of the study protocol (including foreseeable risks and possible side effects) and must sign and date an IRB [Institutional Review Board]-approved Informed consent Form [ICF] (including Health Insurance Portability and Accountability Act authorization, if applicable) before performance of any study specific procedures or tests.

Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with steroids may be included in the study if they have recovered from the acute toxic effect of radiotherapy. A minimum of 4 weeks must have elapsed between the end of whole brain radiotherapy and study enrollment (2 weeks for stereotactic radiotherapy).
