Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 24 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I, Open-label, Dose Escalation, Non-randomized Study to Assess the Pharmacokinetics, Dose Limiting Toxicity, and Maximum Tolerated Dose of OPB-31121 in Subjects With Advanced Solid Tumors
Study Start Date : June 2009
Actual Primary Completion Date : November 2012
Actual Study Completion Date : November 2012

Arm Intervention/treatment
Experimental: OPB-31121
OPB-31121 50 mg by mouth 2 times a day on Days 1-21 of each 28-day cycle.
Drug: OPB-31121
50 mg by mouth 2 times a day on Days 1-21 of each 28-day cycle.

Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) of OPB-31121 [ Time Frame: 4 Week Cycle ]
    The MTD is defined as the highest dose level at which < 2 of 6 subjects experience dose limiting toxicity (DLT) during the first cycle.

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:

  1. Subjects with histologically or radiologically confirmed solid tumors refractory to standard therapy, for which there is no standard therapy, or are not eligible for standard therapy. Subjects must have at least one measurable lesion.
  2. Male and female subjects >/= 18 years of age.
  3. Male and female subjects who are surgically sterile; female subjects who have been postmenopausal for at least 12 consecutive months; or male and female subjects who agree to remain abstinent or to begin TWO acceptable methods of birth control from one week prior to drug administration through 30 days (for females) and 90 days (for males) from the last dose of study medication. If employing birth control, two of the following precautions must be used: vasectomy, tubal ligation, vaginal diaphragm, intrauterine device (IUD), condom, diaphragm, cervical cap or sponge with spermicide.
  4. Eastern Cooperative Oncology Group (ECOG) performance status: </= 2
  5. Subjects must have a life expectancy of longer than 3 months.
  6. Adequate vital organ function as follows: Neutrophils: >/= 1,500/microliter; platelets: >/= 75,000/microliter; hemoglobin: >/= 9.0 g/dL; Aspartate transaminase (AST), Alanine transaminase (ALT): </= 2.5 * ULN with the exception of subjects with liver metastases. In these cases, AST, ALT </= 5 * ULN for eligibility; serum total bilirubin: < 2.5 * ULN. Subjects must have a normal serum creatinine with a measured 24 hour creatinine clearance of > 60 cc/min; INR < 1.5
  7. Ability to provide written informed consent prior to initiation of any study-related procedures, and ability, in the opinion of the principal investigator, to comply with all the requirements of the study.
  8. Subjects, who have received prior therapy, eg, chemotherapy, radiotherapy, or surgery, must have stopped therapy for >/= 4 weeks prior to drug administration. Subjects who have received targeted or immunotherapy must have stopped therapy for 5 half lives or 4 weeks prior to drug administration, whichever is earlier, and recovered from any prior toxicity not mentioned above to at least Grade 1.
  9. Subjects must have a normal ejection fraction (>/= 50%) as measured by either echocardiogram or multi gated acquisition (MUGA) scan.

Exclusion Criteria:

  1. Uncontrolled intercurrent 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 study requirements.
  2. Known central nervous system (CNS) metastasis.
  3. Presence of active gastrointestinal disease or other condition (eg, significant bowel resections) which has the potential to significantly affect the absorption of the study drug, in the opinion of the investigator or sponsor.
  4. Known history of or concurrent hepatitis or acquired immunodeficiency syndrome (AIDS) or known carriers of hepatitis B surface antigen (HBsAg) and/or hepatitis C antibodies (anti-HCV), or human immunodeficiency virus (HIV) antibodies.
  5. Subjects who are pregnant or breast feeding. A negative urine pregnancy test must be confirmed prior to the first dose of study drug for women of child bearing potential (WOCBP).
  6. Administration of another investigational agent within 28 days or 5 half-lives for targeted therapy or immunotherapy (whichever is shorter) prior to study entry
  7. Use of prohibited medications
  8. Subjects with history of coagulopathy (or taking anticoagulants) including deep vein thrombosis (DVT)/pulmonary embolism (PE), myocardial infarction or stroke within the last 6 months.
