Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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.
• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
• Patients must be at least 18 years of age.
• 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.
• 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.
• Patients must provide written informed consent.
• 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,
• Sexually abstinent or correct and consistent use of one of the following methods of birth control in addition to a male partner using a condom from Screening to 3 months after the last dose of study drug:
• hormone-containing contraceptive intrauterine device with a failure rate of < 1% per year,
• cervical cap or diaphragm with a spermicidal agent,
• tubal sterilization, or
• vasectomy in male partner. Male patients must agree to sexual abstinence or to consistently and correctly use a condom in combination with one of the above methods of birth control from Screening to 3 months after the last dose of study drug.
• Life expectancy must be ≥ 3 months.

You may not qualify if…

• Has received systemic anti-cancer therapy within the 3 weeks prior to starting the trial.
• Has received radiotherapy within the 28 days prior to first dose or within 12 weeks for patients with glioblastoma, with the exception of palliative radiotherapy to focal lesions for pain or other symptom control.
• Has received major surgery within the 4 weeks prior to starting the trial.
• 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.
• 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.
• Is pregnant or lactating.
• Had prior malignancy other than carcinoma in situ of the cervix or non-melanoma skin cancer, unless that prior malignancy was diagnosed and definitively treated at least 3 years previously with no subsequent evidence of recurrence. 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.
• Has a corrected QT interval (QTc) > 470 ms or has an electrocardiogram (ECG) with a new abnormal finding that is clinically significant.
• 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.
• Has inability to take oral medications and/or has clinical or radiological diagnosis of bowel obstruction.
• Had prior treatment with napabucasin (BBI-608).
• Is not able to avoid the concomitant use of proton pump inhibitors (PPIs) or histamine H2-receptors antagonists, which have long-lasting pH-elevating effects, during DSP-0337 dosing, or avoid the use of antacids until at least 2 hours after dosing.
• Has a known history of human immunodeficiency virus (HIV) infection, active hepatitis B, or untreated hepatitis C; patients who have completed a course of antiviral treatment for hepatitis C are eligible.
• Has inability to comply with the protocol or study procedures.
