Autologous iPSC-Derived Dopamine Neuron Transplantation for Parkinson's Disease

Официальное название

A Phase 1 Clinical Trial of Autologous iPSC-Derived Dopamine Neuron Transplantation for Parkinson's Disease

Обзор

This research study is evaluating an investigational cell product called autologous induced pluripotent stem cell (iPSC)-derived dopamine neurons. This research study is a single-center Phase 1/2a clinical trial, which will test the safety of injecting the investigational cell product into the brain of subjects with Parkinson's disease.

Подробное описание

The goal of this research study is to test a new treatment for Parkinson's disease. Parkinson's disease is a progressive disease that causes people to lose specific brain cells called midbrain dopamine neurons. When these dopamine neurons are lost, it leads to a lack of dopamine in the brain. When there is not enough dopamine, people with Parkinson's disease experience problems with their movement. This trial will test whether new dopamine neurons made from blood cells from subjects with Parkinson's disease are safe when surgically injected into the area of the brain affected (called the putamen) of the same subjects (called autologous transplantation). The trial will assess the safety of the injected cells and will also measure the effects of the transplanted autologous dopamine neurons on Parkinson's disease symptoms.

At this time, autologous iPSC-derived midbrain dopamine neurons are available only through participation in the ongoing Phase 1/2a clinical trial. Expanded access or compassionate use outside of the trial is not available.

Вмешательства

• Биопрепарат Autologous midbrain dopamine neurons
  The autologous midbrain dopamine neurons are a experimental cryopreserved cell product derived from human autologous induced pluripotent stem cells. The autologous midbrain dopamine neurons will be surgically administered into the putamen, unilaterally, in a single surgical session.

• Ingestion of investigational drug or recipient of investigational procedure within 6 months prior to trial.
• Subjects with active cardiovascular and cerebrovascular disease within 6 months prior to signing the informed consent form:

• History of severe heart failure (congestive heart failure of New York Heart Association Class II or above or left ventricular ejection fraction < 35% by any examination method), unstable angina pectoris and myocardial infarction
