20. Patient cannot:
* Anticipate any significant problems with transportation arrangements or available time to travel to the study site and have any plans to move within the next months to a location which would make continued participation in the study' impractical.
* Be involved in any unresolved legal problems that could jeopardize continuation or completion of the study.
* Have any pending charges for violent crime (not including Driving Under the Influence (DUI) offenses).

22. Has been previously treated in this study or randomized or treated in any other study employing TMP-301 (i.e., subject may not have received study drug and then reenrolled).
23. Any condition not identified in the protocol that in the opinion of the investigator would confound the evaluation and interpretation of the study data or may put the subject at risk.
