E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the long-term safety and tolerability of RSG XR in subjects with mild-to-moderate AD who have completed either Study AVA102670 or AVA102672. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective of this study is to explore further the long-term efficacy of RSG XR on cognitive function and overall clinical response in subjects with mild tomoderate AD who have completed either Study AVA102670 or AVA102672. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects eligible for enrollment in the study must meet all of the following criteria: 1. Male or female subject who has successfully completed Visit 10 of AVA102670 or AVA102672 without safety/tolerability issues, where in the opinion of the subject/carer and of the investigator, it would be beneficial to receive RSG XR. However subjects who have completed of the double-blind treatment phase may still be eligible for entry if they withdraw during the last 6 weeks of AVA102670 or AVA102672 due to any reason other than safety (subjects who withdraw from AVA102670 or AVA102672 due to safety/tolerability issues during the last 6 weeks of treatment will not be eligible to enter this study). 2. Female subjects able to bear children must agree to use an adequate method of contraception for the duration of the study (See Appendix 11.1 for details of highly effective methods to avoid pregnancy). Female subjects who are pre-menopausal or who have been post-menopausal for <1 year must undertake pregnancy testing (urine test) ≤7 days before Visit 1, which must be negative1. 3. Subject is willing to participate in the extension study and has provided full written informed consent prior to the performance of any protocol-specified procedure; or if unable to provide informed consent due to cognitive status, full written informed consent on behalf of the subject has been provided by a legally acceptable representative (where this is in accordance with local laws, regulations and ethics committee policy). 4. Subject lives with (or has substantial periods of contact with) a regular caregiver who is willing to attend all visits, oversee the subject's compliance with protocol-specified procedures and study medication, and report on subject's status2. 5. Subject has the ability to comply with procedures for cognitive and other testing. 6. Caregiver has provided full written informed consent on his or her own behalf prior to the performance of any protocol-specified procedure. 7. Subjects considered for enrolment must have a QTc (either QTc B (Bazett's correction) or QTc F (Fridericia's correction)) <450msec at Visit 1, with the exception of subjects with bundle branch block (for whom either QTc B or QTc F must be <480msec)3. 8. In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category. |
|
E.4 | Principal exclusion criteria |
Subjects meeting any of the following criteria must not be enrolled in the study: 1. Subject had a serious adverse experience or clinically significant laboratory abnormality during AVA102670 or AVA102672, which in the opinion of the investigator could have been attributable to study medication, and which is ongoing at Visit 1. 2. The subject is felt by the investigator to be unsuitable (on the basis of health, compliance, caregiver availability, or for any other reason) for inclusion in the study. 3. The subject experienced a significant cardiovascular event during AVA102670 or AVA102672 (e.g. intervention, percutaneous coronary intervention, vascular surgery, acute coronary syndrome [non Q-wave myocardial infarction, Q-wave myocardial infarction, unstable angina] or significant arrhythmia), unless a thorough cardiovascular evaluation has been performed which confirms that the subject does not have congestive heart failure, and is clinically stable. 4. Clinical/investigational evidence of congestive heart failure defined by the New York Heart Association (NYHA) criteria (Class I to IV cardiac status) at the time of Visit 1. 5. Clinically significant peripheral oedema at the time of Visit 1. 6. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), or alkaline phosphatase values >2.5 times the ULN, total bilirubin values >1.5 times the upper limit of normal (ULN), or history of severe hepatobiliary disease (e.g. hepatitis B or C, or cirrhosis, Child-Pugh Class B/C). In Canada only, the following change will be made to Exclusion Criteria number 6. ALT, AST, or alkaline phosphatase values >2.0 times the ULN, total bilirubin values >1.5 times the ULN, or history of severe hepatobiliary disease (e.g. hepatitis B or C, or cirrhosis, Child-Pugh Class B/C). 7. Subject is an immediate family member or employee of the participating Investigator, of any of the participating site staff, or of GSK. 8. In France, a subject is neither affiliated with nor a beneficiary of a social security category. 9. In France, a subject has participated in any study using an investigational drug during the previous 30 days (except for participation in AVA102670 or AVA102672). |
