IGC Completes the Final Cohort of Its Phase 1 Clinical Trial on Alzheimer's Patients

India Globalization Capital, Inc. ("IGC" or the "Company") (NYSE American: IGC) announces today it has completed Cohort 3 of its Phase 1 clinical trial on IGC's tetrahydrocannabinol ("THC")-based investigational new drug, IGC-AD1, intended to alleviate the symptoms of individuals suffering from Alzheimer's disease. As previously disclosed, IGC submitted IGC-AD1, its investigational drug candidate for Alzheimer's, to the U.S. Food and Drug Administration ("FDA") under Section 505(i) of the Federal Food, Drug, and Cosmetic Act. IGC received approval to proceed with the Phase 1 trial, on Alzheimer's patients, from the FDA on July 30, 2020. Cohort 3 is the final cohort in IGC's Alzheimer's Phase 1 trial. The Data and Safety Monitoring Committee ("DSMC") for IGC's clinical trial will review the data from Cohort 3, and IGC will report its findings from all three Cohorts to the FDA.

As previously announced, for Cohort 1, we administered one dose of the investigational new drug IGC-AD1 per day to Alzheimer's patients, which we increased to two doses in Cohort 2 for the same Alzheimer's patients, and to three doses in Cohort 3. This Phase 1 trial focuses on the safety and tolerability of IGC-AD1 on patients suffering from mild to severe Alzheimer's. Daily, we monitored and recorded certain solicited adverse events, such as somnolence, falls, dizziness, asthenia, suicidal ideation, hypotension, hypertension, psychiatric symptoms, seizures, paradoxical nausea and vomiting. We also monitored unsolicited adverse events such as urinary tract infections and other abnormalities. All adverse events were tabulated and measured using a severity scale and compared against trial halting rules.

To IGC's knowledge, this is the first human clinical trial using low doses of natural THC, a psychoactive member of the cannabinoid class of natural products produced by the Cannabis sativa plant, on Alzheimer's patients. We are motivated by the potential that, with future successful results from appropriate further trials, IGC-AD1 could contribute to relief for some of the 50 million people around the world expected to be impacted by Alzheimer's disease by 2030 (WHO, 2020).
