• QTc interval > 450 msec for males or > 470 msec for females or any clinically significant ECG abnormalities that, in the Investigator's opinion, would compromise the subject's safety for inclusion in the study. Significant history or current evidence of risk factors for Torsade de Pointes (TdP) (e.g., cardiac disease, heart failure, clinically significant hypokalemia or other electrolyte disorders, family history of Long QT Syndrome), as determined by the Investigator.
• History or current evidence of myasthenia gravis or myasthenic syndrome.
• History or current evidence of epilepsy, other seizures disorders, or other risk factors that may predispose to seizures or lower the seizure threshold; tendinitis or tendon rupture; peripheral neuropathy or aortic aneurysms.

• Presence of a medical condition requiring regular treatment with prescription drugs (except hormonal contraceptives).
• Use of pharmacologic agents (prescription or over-the-counter) or herbal products known or suspected to induce or inhibit drug-metabolizing enzymes (especially inducers and inhibitors of CYP1A2 and CYP2C9) within 30 days before initial dosing.
• Use of dietary products (e.g., grapefruit products of all types) known or suspected to induce or inhibit drug-metabolizing enzymes (especially inducers and inhibitors of CYP1A2 and CYP2C9) within 14 days before initial dosing.
