hours prior to the first dose of BAL101553; women of childbearing potential must agree
to use highly-effective contraceptive methods for the duration of study participation
and for an additional 90 days after the last dose of study drug; highly-effective
contraceptive methods include male or female sterilization (bilateral tubal occlusion
or vasectomy); intrauterine device (IUD); combined (estrogen- and
progesterone-containing) hormonal contraception (oral, vaginal ring or transdermal
patch) with an ethinylestradiol dose of at least 30 ug, plus use of male condoms
(preferably with spermicides), female condoms, a female diaphragm or a cervical cap;
or total sexual abstinence; should a woman become pregnant or suspect she is pregnant
while participating in this study, she should inform her treating physician
immediately; male patients must agree not to donate sperm from the first dose of study
drug until 90 days after the end of treatment; male patients, without a vasectomy and
with a partner of childbearing potential, must agree to use condoms during the study
and for at least 90 days after the end of treatment; the patient should be instructed
that their female partner should use another form of contraception for the duration of
the study and continue this use for at least 90 days after the last dose of study drug
- Patients must have no concurrent malignancy except curatively treated basal or
squamous cell carcinoma of the skin or carcinoma in situ of the cervix, breast, or
bladder; patients with prior malignancies must be disease-free for >= 5 years
- Patients must be maintained on a stable corticosteroid regimen (no increase for 5
days) prior to the start of treatment
- Patients must be able to swallow whole capsules
Exclusion Criteria:
- Patients receiving any other investigational agents
- Patients with a history of allergic reactions attributed to compounds of similar
chemical or biologic composition to BAL101553
- Patients on drugs that are strong inhibitors and/or inducers of CYP2C9, CYP2C19 or
CYP3A4 (including enzyme-inducing anti-epileptic drugs [EIAEDs]), are not eligible for
treatment under this protocol; patients taking non-EIAEDs are permitted to take part
in the study; patients previously treated with any of the prohibited concomitant
medications listed above may be enrolled if they have been off of the medication for
>= 10 days prior to the first dose of BAL101553
- Patients may not be on coumarin anti-coagulants (warfarin, etc.); heparin,
low-molecular weight heparin (LMWH), or other antithrombotic medications are permitted
- Patients with gastrointestinal disease, or those who have had a procedure that is
expected to interfere with the oral absorption or tolerance of BAL101553 (e.g.,
functionally-relevant gastrointestinal obstruction, or frequent vomiting unresolved
upon anti-emetic supportive care)
- Patients with peripheral neuropathy >= Common Terminology Criteria for Adverse Events
(CTCAE) grade 2
- Patients with ataxia >= CTCAE grade 2
- Patients with known acute or chronic hepatitis B or hepatitis C infection \
- Patients with systolic blood pressure (SBP) >= 140 mmHg or diastolic blood pressure
(DBP) >= 90 mmHg at the screening visit are ineligible; patients with an initial
clinic blood pressure (BP) >= 140/90 mmHg may be included if SBP < 140 mmHg and DBP <
90 mmHg is confirmed in two subsequent BP measurements on the same day
- Patients with blood pressure (BP) combination treatment with more than two
antihypertensive medications are ineligible
- Significant cardiac disease or abnormality, including any one of the following:
- Left ventricular ejection fraction < 50% at screening (assessed by
echocardiography, cardiac MRI or multigated acquisition [MUGA])

electrocardiogram (ECG), or a clinically-relevant ECG abnormality

- Bradycardia (heart rate < 50 bpm)
- Complete left bundle branch block.
- Bifascicular block (complete right bundle branch block and anterior or posterior
left hemiblock)
