What You Need to Know Before You Apply

What is the purpose of this trial?

This clinical trial is designed to test the safety and tolerability of injecting ANPD001 cells that will mature into dopamine-producing cells into the brain of participants with Parkinson Disease. All participants will have ANPD001 cells manufactured from their own previously collected cells.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you must be able to temporarily stop anticoagulation or antiplatelet therapy for at least 2 weeks.

What safety data exists for ANPD001 or similar treatments for Parkinson's Disease?

The treatment DL-3-n-butylphthalide (NBP), which may be similar to ANPD001, was tested in a study with Parkinson's patients and found to be generally safe, with only mild stomach-related side effects reported. ^{1 2 3 4 5}

How does the drug ANPD001 differ from other treatments for Parkinson's disease?

ANPD001 is unique because it may target the genetic and molecular mechanisms underlying Parkinson's disease, potentially slowing or halting its progression, unlike current treatments that primarily manage symptoms. ^{6 7 8 9 10}

What data supports the effectiveness of the drug ANPD001 for Parkinson's Disease?

The research mentions a study where a drug previously approved for diabetes treatment showed potential as a disease-modifying therapy for Parkinson's Disease, suggesting that similar approaches could be effective. However, there is no direct evidence provided for ANPD001 specifically. ^{11 12 13 14 15}

Are You a Good Fit for This Trial?

This trial is for individuals with Parkinson's Disease who are willing to have cells, previously collected from their own bodies, modified and injected back into their brain. The details of the eligibility criteria were not provided.

Inclusion Criteria

I am between 50 and 70 years old.

I was diagnosed with Parkinson's Disease over 4 years ago.

Met all eligibility requirements for inclusion in the trial-ready cohort in clinical study ANPD001-01

Exclusion Criteria

I cannot have an MRI or use gadolinium due to health reasons.

Unable to comply with the protocol procedures, including frequent and prolonged follow-up assessments

I've had brain surgery that makes me ineligible for ANPD001 treatment.

Published Research Related to This Trial

Using advanced gene-editing techniques, researchers created isogenic human A9 dopaminergic neurons to study the effects of parkin mutations linked to early-onset Parkinson's disease, demonstrating a clear causal relationship between these mutations and neuronal dysfunction.

The study found that parkin mutations significantly reduced the frequency of spontaneous action potentials in these neurons, indicating that parkin is essential for maintaining normal dopamine transmission, which is crucial for controlling movement.
