Substantial protocol amendments (globally) | |||
Were there any global substantial amendments to the protocol? Yes | |||
Date | Amendment | ||
01 Mar 2004 | To allow patients to receive study drug for as long as the patient should require it. Also, it changed the frequency of bone marrow cytogenetics for those patients maintaining a complete cytogenetic response to annually from twice yearly until the patient reached month 48 of the extension or 31-July-2006, whichever date came first. | ||
01 Mar 2008 | To accommodate patient site visits on a yearly (±3 months) basis rather than every six months. In addition, a new section was added to include new protocol deviation language which stated that under no circumstances were protocol deviations allowed. | ||
Interruptions (globally) | |||
Were there any global interruptions to the trial? No | |||
Limitations and caveats | |||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
