E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
GE-067-007 will determine the level of association between brain uptake of [18F]flutemetamol and brain amyloid levels. Assessments will be based on analysis of PET images and the quantitative immunohistochemical estimates of levels of amyloid as determined from post-mortem analysis of corresponding brain tissue samples. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the sensitivity of blinded visual interpretations of [18F]flutemetamol PET images without anatomic brain images for detecting brain fibrillar Aβ assessed pathologically post-mortem. |
|
E.2.2 | Secondary objectives of the trial |
(1) To determine the specificity of the visual interpretations of [18F]flutemetamol PET images without anatomic brain images.
(2) To determine the sensitivity and specificity of blinded visual interpretations of [18F]flutemetamol PET images with CT anatomic brain images, for detecting brain fibrillar Aβ assessed pathologically post-mortem.
(3) To determine the level of association between global and regional estimates of brain uptake (SUVR) of [18F]flutemetamol and corresponding estimates of brain fibrillar Aβ levels made post-mortem. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
(1) The subject has a short life expectancy (approximately 1 year or less) as estimated by the Investigator.
(2) The subject is 55 years of age or older and has been diagnosed with a terminal illness.
(3) Informed consent has been signed and dated by the subject and/or the subject’s legally acceptable
representative if applicable, in accordance with local regulations.
(4) The subject has a caregiver who is reliable and will ensure that the subject complies with the protocol, if
necessary in the judgment of the Investigator.
(5) The subject’s general health is adequate to undergo the study procedures.
(6) For women who are either surgically sterile (have had a documented bilateral oophorectomy and/or
documented hysterectomy) or are postmenopausal (cessation of menses for more than 2 years), enrollment
in the study without a pregnancy test at screening is allowed. For women of childbearing potential, the
results of a serum and urine human chorionic gonadotropin pregnancy test (with the result known on the
day of and before the Flutemetamol F 18 Injection administration) must be negative.
(7) The subject is able to tolerate undergoing diagnostic quality anatomic brain imaging (usually CT).
|
|
E.4 | Principal exclusion criteria |
(1)The subject has known or suspected structural brain abnormalities, such as infarcts or tumors, which may interfere with the interpretation of PET images.
(2)The subject has a contraindication for PET.
(3)The subject is pregnant or lactating.
(4)The subject has a known or suspected hypersensitivity/allergy to [18F]flutemetamol or to any of the excipients.
(5)The subject is unable to tolerate or cooperate with study procedures.
(6)The subject has participated in any clinical study using an investigational agent within 30 days of signing consent. |

E.5 End points |
E.5.1 | Primary end point(s) |
The blinded visual assessment of each subject’s Flutemetamol F 18 Injection brain PET images as normal or abnormal without anatomic brain images for reference will be performed by 5 independent blinded readers trained in the evaluation of PET fibrillar Aβ imaging. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
PET image within 35 days after screening. For patients who die during the study histopathology data will be available following post mortem examination and histopathology assessments. |
|
E.5.2 | Secondary end point(s) |
For specificity, the endpoint will be the same as the primary endpoint. For the other secondary objectives, the global and region-specific SUVR values will be the endpoints. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
PET image within 35 days after screening. For patients who die during the study histopathology data will be available following post mortem examination and histopathology assessments. |
