  • 7.5.1 Inclusion criteria (Prodromal)
  • For Screening:
• Confirmation that participant is eligible based on centrally determined predictive criteria including the University of Pennsylvania Smell Identification Test (UPSIT).
  • For participants in PPMI Remote, referral to the clinical site confirms predictive eligibility.
  • For participants identified by the clinical site, predictive criteria are based on generalized risk such as first degree biologic relative, known risk of PD including RBD, or known genetic variants associated with PD risk.
  • Additionally, confirmation of UPSIT eligibility during the Screening visit prior to SPECT Imaging.
• Male or female age 60 years or older (except age 30 years or older for SNCA, or rare genetic variants (such as Parkin or Pink1) participants).
• Individuals taking any of the following drugs: alpha methyldopa, methylphenidate, amphetamine derivatives or modafinil, must be willing and medically able to hold the medication for at least 5 half-lives before SPECT imaging.
• Able to provide informed consent.
• Either is male, or is female and meets additional criteria below, as applicable:
  • Female of childbearing potential who is not pregnant, lactating, or planning pregnancy during the study and has a negative pregnancy test on day of Screening SPECT imaging test prior to injection of DaTscanTM.
  • For continuation to Baseline visit and ongoing follow-up:
• Confirmation that participant is eligible based on \*Screening SPECT imaging.
  • Screening SPECT Imaging eligibility:
  • Based on the results of the SPECT imaging test, Prodromal participants eligible to continue their participation in PPMI Clinical will be asked to return for their PPMI Clinical baseline visit. Neither the participant nor the site investigator will be made aware of the participant's DAT status during the study.
• It is anticipated that approximately 6,000 participants will complete a screening visit to undergo DAT imaging. Approximately 2,000 participants will be eligible to continue their participation in PPMI Clinical (those not eligible to proceed will remain in PPMI Remote, as applicable).
• All participants with DAT deficit will be eligible to continue their participation in PPMI Clinical. It is estimated that about 75% of eligible participants will have a DAT deficit (defined by a hybrid of visual assessment and quantitative striatal specific binding analysis).
• Some participants without DAT deficit will also be eligible to continue their participation in PPMI Clinical. These participants will be chosen based on DAT binding that is reduced from age expected but it not outside the normal range and/or from individuals with high-risk of PD including RBD, LRRK2, GBA, SNCA, or rare genetic variants (such as Parkin or Pink1) that do not demonstrate DAT deficit. It is estimated that about 25% of eligible participants will not have a DAT deficit.
• It is anticipated that approximately 30% of the PPMI Clinical prodromal participants with DAT deficit will phenoconvert to motor parkinsonism during a 3 to 5-year follow-up.
  • 7.5.2 Exclusion Criteria (Prodromal)

• Condition that precludes the safe performance of routine lumbar puncture, such as prohibitive lumbar spinal disease, bleeding diathesis, or clinically significant coagulopathy or thrombocytopenia.
• Any other medical or psychiatric condition or lab abnormality, which in the opinion of the investigator might preclude participation.
• Currently taking levodopa, dopamine agonists, MAO-B inhibitors, amantadine or another PD medication, except for low-dose treatment of restless leg syndrome (with permission of medical monitor).
• Has taken levodopa, dopamine agonists, MAO-B inhibitors or amantadine within 60 days of Baseline visit. except for low-dose treatment of restless leg syndrome (with permission of medical monitor).
• Any other reason that, in the opinion of the investigator, would render the participant unsuitable for study enrollment.
