I have been informed that I should inquire of the attending physician whether or not 
there are any sen/ices, investigational agents or devices, and/or medications being 
offered by the sponsor of this clinical research project at a reduced cost or without 
cost. Should the investigational agent become commercially available during the 
course of the study, I understand that I may be required to cover the cost of 
subsequent doses. 
Costs related to my medical care including expensive tests or procedures shall be my 
responsibility. I have been given the opportunity to discuss the expenses or costs 
associated with my participation in this research activity. 
It is possible that this research project will result in the development of beneficial 
treatments, new drugs, or possible patentable procedures, in which event I herein 
disclaim and hereby waive any right or claim to receive any compensation or benefits 
from the subsequent use of information acquired and developed through participation 
in this research project. 
I understand that practicing effective contraception is medically necessary and a 
prerequisite for my participation in this clinical research study. Should contraception 
be interrupted or if there is any suspicion of pregnancy, my participation in this clinical 
research study will be terminated at the sole discretion of the investigator. 
I may discuss any questions or problems during or after this study with Dr. Jack A. 
Roth at (713) 792-6932. In addition, I may discuss any problems I may have or any 
questions regarding my rights during or after this study with the Chairman or the 
Surveillance Committee at (713) 792-3220 and may in the event any problem arises
