E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Main efficacy objective:• To investigate the effect of Apovir on disease progression of AD as assessed by the Alzheimer’s Disease Assessment Scale-Cognitive Subscale [ADAS-cog] compared to placebo
Main safety objective: • To investigate the safety and tolerability of the combination therapy of Apovir in patients with AD
|
|
E.2.2 | Secondary objectives of the trial |
• To investigate the effect of Apovir on disease progression of AD assessed by cognitive tests – (Mini Mental State Examination [MMSE], ADAS-cog, Alzheimer’s Quick Test [AQT] and Clinical Dementia Rating [CDR])
• To investigate the plasma and cerebrospinal fluid concentrations of Apovir (APO-P001 and ribavirin) in patients with AD
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female patients diagnosed with AD according to ICD-10
2. 60–85 years at the time of screening
3. Mini Mental State Exam score 21–27 and judged by the Investigator to be able to give informed consent
4. Patients have adequate hearing, vision, and language skills to perform neuropsychiatric testing and interviews as specified in the protocol, as judged by the Investigator
5. 12-lead ECG with normal tracings; or changes that are not clinically significant and do not require medical intervention, as judged by the Investigator
6. Patient has a relative or caregiver, judged to be reliable by the Investigator, who has signed informed consent. The relative or caregiver should participate in the patient’s visits at the clinic and assist the patient with drug compliance.
7. Willingness to participate after signing informed consent |
|
E.4 | Principal exclusion criteria |
1. Active hepatitis B, active hepatitis C, or HIV infection
2. Serious cardiac disease including unstable or uncontrolled cardiac disease during the last 6 months and/or previous history of deep vein thrombosis or clinical signs of deep venous thrombosis
3. Major surgical procedure within 4 weeks prior to inclusion
4. Patients on unstable treatment with AChI and / or Memantine for dementia. Unstable treatment is defined as initiated treatment or changed treatment or dose within 3 months prior to the baseline visit (i.e. patients on stable AChI / Memantine treatment and patients without AChI / Memantine treatment can be included in the trial) If patients receive treatment with AChI for dementia this treatment should have been unchanged regarding drug(s) and dose(s) for at least 3 months prior to the baseline visit (patients on an unchanged AChI dose/medication and patients without AChI treatment can be included in the trial)
5. Men without reliable contraceptive method if sexually active with WOCBP. For purposes of this trial, WOCBP include any female who has experienced menarche, who has not undergone tubal ligation, and who is not postmenopausal. Post menopause is defined as: amenorrhea ≥ 12 consecutive months without another cause.
6. Participation in any other clinical trial within 30 days of inclusion (randomisation) in the trial or patients with unresolved investigational treatment-related adverse events
7. Other chronic disease or previous organ transplantation judged by the Investigator to interfere with the assessment of treatment success and/or ability to fully participate in the trial
8. Impaired kidney function with a glomerular filtration rate (GFR) calculated from cystatin C <60 mL/min
9. Calculated ribavirin dose at screening is <600 mg/day* according to the following formula:
0.244 x 10ax 24b x (0.122 x GFR + 0.0414 x body weight in kg)
when a Target concentration=10 mmol/L and b Dosing frequency=24 hours
* If the ribavirin/placebo starting dose is adjusted to 400mg/day the calculated ribavirin dose may be <600mg/day, but must not be <400mg/day at screening.
10. Known blood disease or Anaemia Haemoglobin < 120g/L for women and <130 g/L for men
11. Known haemoglobinopathy (e.g. thalassemia and sickle cell anaemia)
12. Patients that require immunosuppressive treatments including azathioprin, ciclosporin, systemic steroid treatment (e.g. prednisolone at doses of ≥10 mg/day or hydrocortisone) or has received such treatment within the last 6 months prior to randomization
13. Patients that are treated with drugs that can interact significantly with APO-P001; ethinylestradiol and/or ribavirin; azathiopin, didanosine, zidovudine, mercaptopurine, stavudine
14. Lack of suitability for participation in the trial, for any reason, as judged by the Investigator |
