Autologous Bone Marrow Aspirate (IV) and Bone Marrow Concentrate (Intranasal) for Parkinson's Disease and Parkinson-Plus Syndromes (SPARC-PD)

Overview

This pilot study evaluated the safety, tolerability, and exploratory epigenetic outcomes of a single same-day autologous bone marrow procedure in adults with Parkinson's disease (PD) or Parkinson-plus syndromes (PPS). Ten participants underwent posterior superior iliac spine bone marrow aspiration under local anesthesia. The unprocessed aspirate (BMA) was filtered and administered intravenously via normal saline infusion on the same day. A portion of the aspirate was centrifuged to produce a bone marrow aspirate concentrate (BMAC), which was atomized intranasally using a mucosal atomization device. Cells were not expanded in culture or genetically modified. The procedure was performed under the Same Surgical Procedure exception (21 CFR 1271.15(b)); an investigational new drug application (IND 31770) was submitted to the FDA Center for Biologics Evaluation and Research (CBER). The primary outcome was safety and tolerability, assessed by treatment-emergent adverse events (TEAEs) graded per CTCAE v5.0 criteria through 12 months post-treatment. Exploratory outcomes included DNA methylation biological age (GrimAge-based composite and organ/system Systems Age clocks) measured from peripheral blood at baseline and approximately 6 months, and characterization of the delivered cell product by automated hematology and multiparameter flow cytometry.

Parkinson's disease (PD) and Parkinson-plus syndromes (PPS), including progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal syndrome (CBS), and Lewy body dementia (LBD), are progressive neurodegenerative disorders characterized by motor dysfunction, non-motor symptoms, and progressive disability. Currently available therapies are primarily symptomatic and do not alter the underlying neurodegenerative process. Autologous bone marrow aspirate contains mesenchymal stromal cells (MSCs), hematopoietic progenitor cells, and numerous trophic, immunomodulatory, and anti-inflammatory bioactive factors that may support neuronal repair and tissue homeostasis. Preclinical studies suggest these cells and associated soluble factors may promote neuroprotection by modulating inflammation, oxidative stress, mitochondrial dysfunction, and neurotrophic signaling. Because the cell product is autologous and minimally manipulated, it avoids ex vivo culture expansion and genetic modification and is expected to have low immunogenic potential. Intranasal administration may facilitate transport of cells and soluble factors to the central nervous system through olfactory and trigeminal pathways, while intravenous administration provides systemic exposure. Combining both delivery routes may provide complementary central nervous system and peripheral biologic effects using a single same-day autologous procedure. This pilot study was designed primarily to evaluate the safety and tolerability of combined intravenous bone marrow aspirate (BMA) and intranasal bone marrow aspirate concentrate (BMAC) administration in adults with PD or PPS. Exploratory objectives include evaluation of changes in DNA methylation-derived biological age biomarkers and characterization of the administered autologous cell product.
