protein criteria present to evaluate response. Measurable disease is defined as
having at least one of the following criteria within 28 days prior to registration:

1. Serum M-protein level > 0.5 gm/dl (10.0 g/L) measured by serum protein
electrophoresis.

2. Urinary M-protein excretion > 0.2 g/24 hours by urine electrophoresis.

2. Subjects must have relapsed or resistant disease, defined as either relapsing or is
resistant after > 2 lines of prior therapy for myeloma. A minimum of 42 days must
have elapsed since prior autologous or allogeneic transplant;

3. Informed consent compliant with ZIOPHARM policies and approved by the Human
Investigation Review Committee with jurisdiction over the site;

4. ECOG performance score ≤ 1;

5. No chemotherapy, bortezomib, lenalidomide, thalidomide, arsenic trioxide, radiation
therapy or immune therapy for ≥ 3 w and recovered from all treatment associated
toxicities prior to registration; 5a. Patients may not receive more than the
equivalent of 10 mg of prednisone per day for 2 weeks prior to registration.

6. Age ≥ 18;

7. Granulocytes ≥ 1.0 x 109/L; platelets ≥ 50 x 109/L;

8. Bilirubin ≤ 2.0 mg/dL; AST and ALT ≤ 2 x ULN;

9. Creatinine ≤ 3 X ULN.

10. No investigational agents within 28 days of study entry.

11. Males who agree to use a double-barrier method of birth control, (Double barrier
method is defined as: a condom and either a diaphragm/cervical cap or an IUD).

Exclusion Criteria

1. NYHA functional class ≥ 3, myocardial infarction ≤ 6 mo or uncontrolled cardiac
arrhythmia other than asymptomatic atrial fibrillation; QTc ≥ 450msec; AV-block ≥
grade-2 or LBBB;

2. Women of childbearing potential. (Non-childbearing potential is defined as: surgical
sterilization or 2 years post-menopausal)

3. Active infection requiring antibiotics;

4. Allergy to ZIO-101 or its excipients;

5. Baseline confusion or dementia, defined as grade > 2 CTCAE Version 3.0;

6. Significant neurotoxicityneuropathology, defined as grade > 2 neurotoxicity
neuropathology per CTCAE Version 3.0;

7. Prior seizures ≥ grade-3 in CTC v.3 criteria.

8. Prior history of neurological deficits (e.g., stroke, dementia, ischemia) that has
the potential to confound a post-dose neurological assessment
