A Safety and Pharmacokinetic Study of NBM-BMX Administered Orally to Patients With Advanced Cancer

Inclusion Criteria:

1. Histologically or cytologically confirmed advanced, non-resectable, and/or metastatic
solid tumor refractory to standard of care therapy, or for whom no standard of care
therapy is available, or who were not amenable to established forms of treatment.

2. Solid tumors must have measurable or evaluable disease as per Response Evaluation
Criteria in Solid Tumors (RECIST) 1.1.

3. Female or male at 18 years of age or older.

4. ECOG performance status 0 to 2.

5. Recovered from prior treatment-related toxicity to at least grade 1 with exception of
grade 2 alopecia or other grade 2 toxicity with prior approval of the Medical Monitor.

6. Adequate organ function as defined by the following criteria:

- Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) ≤3 x
upper limit of normal (ULN), or AST and ALT ≤5 x ULN if liver function
abnormalities are due to underlying malignancy

- Total serum bilirubin ≤1.5 x ULN (except for subjects with documented Gilbert's
syndrome)

- Absolute neutrophil count (ANC) ≥ 1500/μL

- Platelets ≥ 90,000/μL

- Hemoglobin ≥ 9.0 g/dL

- Serum creatinine ≤1.5 x ULN or creatinine clearance of ≥ 60 mL/min

7. Signed and dated informed consent document indicating that the subject (or legally
acceptable representative) has been informed of all the pertinent aspects of the trial
prior to enrollment.

8. Willingness and ability to comply with scheduled visits, treatment plans, laboratory
tests, and other study procedures.

Exclusion Criteria:

Subjects presenting with any of the following will not be included in the trial:

1. Major surgery or radiation therapy within 28 days of starting study treatment.

2. Systemic anti-cancer therapy within 28 days or 5 half-lives (whichever is shorter) of
starting study treatment.

3. Prior high-dose chemotherapy requiring hematopoietic stem cell rescue.

4. Current treatment on another clinical trial.

5. Spinal cord compression, carcinomatous meningitis, or leptomeningeal disease unless
appropriately treated and neurologically stable for at least 4 weeks.

6. Any of the following within the 12 months prior to starting study treatment:
myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass
graft, congestive heart failure, or cerebrovascular accident including transient
ischemic attack; within 6 months prior to starting study treatment for pulmonary
embolus. However, upon agreement between the investigator and sponsor, the 6 month
post-event-free period for a subject with a pulmonary embolus can be waived if due to
advanced cancer. Appropriate treatment with anticoagulants is permitted.

7. NYHA Class III or IV heart failure and known history of QTc prolongation or Torsade de
Pointes.

8. Use of medications known to significantly prolong the QTc interval (e.g.,
antiarrhythmic and psychotropic medications).

9. Hypertension that cannot be controlled by medications.

10. Current treatment with therapeutic doses of warfarin (low dose warfarin up to 2 mg PO
daily for deep vein thrombosis prophylaxis is allowed).

11. Known human immunodeficiency virus (HIV)-positive and is receiving antiretroviral
therapy. Subjects with known HIV infection and on a stable dose of HIV suppressive
medication may be eligible if considered to be at low risk for AIDS-related outcomes
following discussion with the medical monitor.

12. Known hepatitis B virus (HBV) or hepatitis C virus (HCV) with evidence of chronic
active disease or receiving/requiring antiviral therapy.

13. History of receiving organ transplantation or immune disorders that require continuous
immunosuppressant agent therapy.

14. Pregnancy or breastfeeding. Female subjects must be surgically sterile or be
postmenopausal, or must agree to the use of effective contraception during the period
of therapy. All female subjects with reproductive potential must have a negative
pregnancy test (serum or urine) prior to enrollment. Male subjects must be surgically
sterile or must agree to use effective contraception during the period of therapy. The
definition of effective contraception will be based on the judgment of the principal
investigator or a designated associate.

15. Other severe acute or chronic medical or psychiatric conditions or laboratory
abnormalities that would impart, in the judgment of the investigator and/or sponsor,
excess risk associated with study participation or study drug administration, which
would make the subject inappropriate for entry into this study.
