Detaljerad beskrivning
Evaluate the safety and tolerability of LBT-3627 in both a single and multiple ascending dose study.
Phase Ia will explore safety and tolerability first in healthy volunteers then followed by Parkinson's patients after a single dose. Dose levels will escalate per cohort.
Phase Ib will explore safety and tolerability in Parkinson's patients after multiple doses. Dose levels will escalate per cohort.

- BMI 18-32 kg/m²
- Vital signs, ECG (QTcF <450 ms male / <470 ms female), and safety labs without clinically significant abnormality; no orthostatic hypotension
- Women of non-childbearing potential, or using highly effective contraception per protocol
Key exclusion criteria
- Immunomodulators / steroids - HV: any (incl. OTC) within 90 days; PD: systemic within 60 days and topical/nasal-inhaled OTC within 7 days (both waivable only with Sponsor approval)
- Vaccine within 60 days (HV) / 45 days (PD) of first dose
