Join Thousands Waiting for Retatrutide
Retatrutide could change the weight loss landscape. Unlike semaglutide or tirzepatide, it activates three hormone receptors simultaneously — and early data shows it:
✅ Outpaced existing GLP-1 medications for weight loss in clinical trials
✅ Improved blood sugar, blood pressure, and cholesterol beyond weight loss alone
✅ Delivered results with a simple once-weekly injection
✅ Now in Phase 3 trials with FDA submission expected in the next 1–2 years
Join the waiting list. One email when it launches — that's it.

A Phase 2 Study of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease
Recruiting
The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 40-80 years with early Parkinson's Disease (PD) who have predicted elevations in the activity of the "leucine-rich repeat kinase 2" ("LRRK2" for short) pathway based on their genetic profile. A DNA test will be used to identify the "LRRK2-driven" population with predicted elevation in the LRRK2 pathway.
Participants will:
• Take NEU-411 or placebo every day for 52 weeks

PPMI Clinical - Establishing a Deeply Phenotyped PD Cohort
Recruiting
The Parkinson Progression Marker Initiative (PPMI) is a longitudinal, observational, multi-center natural history study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson's disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls.
The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability.
