简要总结
This is a long-term-safety roll-over extension study for a Phase II Study (Protocol CPC-001-07).
详细描述
This is a long-term-safety roll-over extension study for a Phase II Study (Protocol CPC-001-07). Patients having safely completed the 12-week maintenance phase of Study CPC-001-07 will be eligible for admission. Subjects will remain on their CPC-201 MTD as determined in Study CPC-001-07. The dose of CPC-201 will be increased from 15 mg/day (administered in Study CPC-001-07) to 20mg/day starting on Day1. For those patients who do not tolerate 20mg/day CPC-201, the dose of CPC-201will be decreased to its previously tolerated level of 15mg/day.
This protocol allows to increase patients' MTD of CPC-201, as previously determined in the Phase II Study (CPC-001-07 protocol) by, 5mg or 10mg increment up to a maximum of 60 mg/day starting on Day7 or Month 3 visits of this extension protocol per Investigator's judgment and patient's tolerability.
This extension study is intended to continue for each enrolled patient for up to 6 months unless medically contraindicated. Patients may withdraw from this study at any time. Upon termination of this study, patients will return to their original daily donepezil dose of 10 mg/day and will continue to receive CPC-201 mg/day for one final week.

- •History or presence of myasthenia.
- •ECG findings of:
- •Complete Left Bundle Branch Block; Ventricular pacing; 2nd degree or 3rd degree AV block; Atrial fibrillation or atrial flutter; HR <45 or >100; PR >220 msec; or QTcF >450 msec in male, >470 msec in female
- •Patients considered unlikely to co-operate in the study, and/or poor compliance anticipated by the investigator.
- •Any other clinically relevant acute or chronic diseases which could interfere with patients' safety during the trial, or expose them to undue risk, or which could interfere with study objectives.
