Why IGC-AD1 & Alzheimer’s?
IGC-AD1 includes two Active Pharmaceutical Ingredients (APIs)
The APIs in IGC-AD1 have been shown to reduce the plaque build-up associated with Alzheimer’s in cell lines.
The API have been shown to promote mitochondrial functioning in pre-clinical studies
The API have been shown to restore spatial memory in a mouse model of Alzheimer’s.
As an oral liquid solution, IGC-AD1 could be an effective, simpler treatment option for patients
The API combination in the oral formulation is patent-protected
IGC-AD1 formulation Incorporate low doses of a plant-derived API.

- THC (∆9-tetrahydrocannabinol) is a psychoactive compound in the cannabis plant that is commonly associated with a euphoric high at high doses
- A low dose of THC is an active pharmaceutical ingredient in IGC-AD1
- The FDA has approved synthetic THC-based formulations for treating nausea and vomiting caused by chemotherapy
How is THC obtained from cannabis? IGC Pharma has production capabilities to safely

Pre-clinical
Study results
The pre-clinical studies tested the API in IGC-AD1 on Alzheimer’s cell lines and Alzheimer’s mouse models and found that it had the potential to be a disease modifying drug that could:

Detailed scientific results
IGC-AD1 reduces Aβ40 peptide production and Aβ42 aggregation in Alzheimer’s cell lines.
Representation of Cao et al., 2014
In Alzheimer’s cell line tests, IGC-AD1 increased Aβ monomers and decreased Aβ aggregation in a dose–dependent manner and decreased Aβ aggregation.
Representation of Cao et al., 2014
IGC-AD1 did not reduce Amyloid Precursor Protein (APP) levels in Alzheimer’s cell lines.
APP modulates cell growth, motility, and survival; it is cut to create small fragments such as the Aβ peptide. Representation of Cao et al., 2014
Memory Improved in Alzheimer’s Mice Model
In a Morris Water Maze test, mice dosed with the active agent in IGC-AD1 had significantly improved times and less errors than those in the control group demonstrating that memory improved in transgenic (APP/PS1) mice with IGC-AD1. group.

Over 48 hours, repeated low-dose exposure to IGC-AD1 was not toxic to Alzheimer’s cells.

The Phase 1 Clinical trial included patients with mild to severe Alzheimer’s. The trial showed that:
- IGC-AD1 is safe and tolerable at three different dosage levels.
- Caregiver distress, and Neuropsychiatric Symptoms (NPS), including agitation, anxiety, and depression improved.
