Brief Summary:
This study will comprise an 18-week open label safety and tolerability trial. In this study, a total of 35 subjects with primary lateral sclerosis PLS or upper motor neuron predominate ALS will be enrolled. At the initial screening evaluation, a baseline T25FW will be obtained. This baseline test will be repeated at weeks 2, 4, 6, 10, 14 18. The validity of this measure was shown in MS studies when compared to the MSWS-12 (12 item walking scale) and CGI (clinical global impression) scales (35-37). A consistent responder will be defined as improvement in 3 of 4 Timed 25Foot Wwalk while on medication, compared with the baseline results while off medication.

  12. Geographically accessible to the site.
  13. Women must not be able to become pregnant (e.g., post-menopausal, surgically sterile, or using adequate birth control methods) for the duration of the study and three months after study completion. Adequate contraception includes: abstinence, hormonal contraception (oral contraception, implanted contraception, injected contraception or other hormonal contraception, for example patch or contraceptive ring), intrauterine device (IUD) in place for ≥ 3 months, barrier method in conjunction with spermicide, or another adequate method.

Exclusion Criteria:

  2. Unwillingness to sign informed consent or any other reasons for which the investigator feels the subject cannot complete the study;
  3. Women who are pregnant, breastfeeding, or trying to become pregnant;
  4. Active cancer within the previous 2 years, except treated basal cell carcinoma of the skin;
  5. Subjects taking any other experimental drugs within 30 days prior to enrollment;
  6. Patient has any history of seizures; brain surgery, brain implants, any metallic implants above the neck, cardiac pacemakers, cochlear implants, piercing or body modification above the neck, known history of TMS related complications or side-effects, tinnitus.
  7. Patient has moderate or severe renal impairment as defined by a calculated creatinine clearance of ≤50 mL/minute;
  8. Patient has been administered botulinum toxin in the lower extremities within 6 months prior to the screening visit and/or is expected to receive botulinum toxin in the lower extremities during the course of the study;
