Brief Summary:
This is a Phase 1, open label, multi-center study of orally administered DSP-0337 in adult subjects with advance solid tumors that are refractory to standard treatment, or for whom no effective therapy exists.

Condition or disease Intervention/treatment Phase
Neoplasms Drug: DSP-0337 Phase 1

Detailed Description:
The study is comprised of two parts: an initial dose escalation phase utilizing a 3 + 3 design to determine maximum tolerated dose followed by a dose expansion cohort in approximately 40 additional subjects. Study participants will initially receive DSP-0337 orally for 28 days (one cycle of treatment). If clinical benefit is seen, treatment can continue until disease progression.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 90 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A First-in-Human Phase I Trial to Determine the Safety and the Pharmacokinetic Profile of DSP-0337 in Patients With Advanced Solid Tumors
Actual Study Start Date : May 15, 2018
Estimated Primary Completion Date : May 2020
Estimated Study Completion Date : June 2020

Arm Intervention/treatment
Experimental: DSP-0337
In Part 1 - Up to six dose levels will be investigated in dose-escalating cohorts to identify a maximum tolerated dose (MTD). An additional subset of patients will be treated to assess the effect of food intake on the PK of DSP-0337 administration at the MTD level. Once the recommended Phase 2 dose (RP2D) has been established, patients will be treated with the RP2D to explore preliminary antitumor activity and safety profile.
Drug: DSP-0337
DSP-0337 will be administered at the following doses in dose-escalation cohorts, maximun tolerated dose (MTD) for food effect, and recommended phase 2 dose (RP2D) for dose-expansion cohort. Dose 1: 200 mg once daily, Dose 2: 200 mg twice daily, Dose 3: 400 mg twice daily, Dose 4: 600 mg twice daily, Dose 5: 800 mg twice daily, Dose 6: 1000 mg twice daily.




Primary Outcome Measures :
  1. Maximum tolerated dose by assessing dose-limiting toxicities (DLTs) [ Time Frame: 4 weeks ]
    Dose escalating cohort

  2. Determination of the Recommended Phase 2 Dose (RP2D) by assessing dose-limiting toxicities (DLTs) [ Time Frame: 4 weeks ]
    Dose escalating cohort


Secondary Outcome Measures :
  1. Number of Patients with Adverse Events [ Time Frame: 12 months ]
    Tolerability will be evaluated based on the adverse events (AEs) recorded at each contact with the patient, physical examinations, and the results of laboratory tests. Toxicity will be graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 4.03.

  2. Pharmacokinetics by assessing drug concentration in blood [ Time Frame: 4 weeks ]
    For food effect, dose escalating cohort

  3. Urine excretion of napabucasin after DSP-0337 administration [ Time Frame: 24 hours ]
    Twenty four-hour urine will be collected and excretion of napabucasin will be evaluated.

  4. Objective response rate (ORR) [ Time Frame: 6 months ]
    Defined as the proportion of patients with a documented complete response or partial response (CR + PR) based on RECIST 1.1.

  5. Time to progression (TTP) [ Time Frame: 6 months ]
    Defined as the time from first dose to the earlier date of assessment of progression by RECIST v1.1.

  6. Progression free survival (PFS) [ Time Frame: 12 months ]
    Defined as the time from first dose to the earlier date of assessment of progression or death by any cause in the absence of progression by RECIST v1.1.

  7. Overall survival [ Time Frame: 12 months ]
    Measured from the date of first dose to the date of death by any cause.


Other Outcome Measures:
  1. Exploratory pharmacodynamic evaluation, including phosphorylated STAT3 (pSTAT3) expression level in patient-derived tumor tissue, as potential biomarkers [ Time Frame: 12 months ]

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

Inclusion Criteria

  1. Histologically or cytologically confirmed diagnosis of advanced cancer in patients with solid tumors that are refractory to standard treatment, or for whom no effective therapy exists.
  2. Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
  3. Patients must be at least 18 years of age.
  4. Organ function must be adequate as follows:

    • Bone Marrow Reserve: absolute neutrophil count ≥ 1.5 x 10^9/L; platelet count ≥ 100 x 10^9/L; hemoglobin ≥ 9.0 g/dL. Must not have required blood transfusion within 1 week of baseline blood count assessment.
    • Hepatic: bilirubin < 1.5 times the upper limit of normal (ULN); alkaline phosphatase (AP), aspartate transaminase (AST), and alanine transaminase (ALT) < 3.0 x ULN (AP, AST, and ALT < 5 x ULN is acceptable if the liver has tumor involvement).
    • Renal: serum creatinine within normal limits; for patients with levels above the institutional normal value, the calculated corrected creatinine clearance must be ≥ 60 mL/min/1.73 m^2 using the Cockcroft-Gault formula corrected for the body surface area.
  5. Toxicities incurred as a result of previous anti cancer therapy (radiation therapy [RT], chemotherapy, or surgery) must be resolved to ≤ Grade 1 except for alopecia and anorexia.
  6. Patients must provide written informed consent.
  7. Female patients are eligible for the study if they meet the following criteria:

    • Are not pregnant or nursing;
    • Of non-childbearing potential defined as women who have had a hysterectomy, bilateral oophorectomy, medically documented ovarian failure, or are documented postmenopausal (follicle stimulating hormone > 40 mIU/mL); OR,

    Of childbearing potential defined as including women < 55 years of age, even those who have experienced 2 years of amenorrhea; all women should also meet both of the following criteria:

    • A negative serum or urine pregnancy test during Screening,

  4. Has significant inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with the study requirements.
  5. Clinically active known brain metastasis unless the brain metastases have been previously treated and are considered stable. Stable brain metastases are defined as no change on computed tomography (CT) scan or magnetic resonance imaging (MRI) for a minimum of 2 months and no change in steroid dose for a minimum of 4 weeks prior to starting the trial.
  6. Is pregnant or lactating.
  7.

If the patient has a medical history of a previous tumor that is not included in this criteria and that the Investigator feels is irrelevant for the objectives of the study, it should be evaluated with the Sponsor or Medical Monitor.
  8. Has a corrected QT interval (QTc) > 470 ms or has an electrocardiogram (ECG) with a new abnormal finding that is clinically significant.
  9. Has a known clinically significant GI disorder(s) including, but not limited to, inflammatory bowel disease or a history of extensive gastric resection and/or small intestinal resection.
  10. Has inability to take oral medications and/or has clinical or radiological diagnosis of bowel obstruction.
