3. GOVERNMENT GRANT

In July 2021, we were awarded a grant from the National Institute on Drug Abuse, or NIDA, of the National Institutes of Health, or NIH, to evaluate the use of cytisinicline as a treatment for cessation of nicotine e-cigarette use. This initial grant award, in the amount of $0.3 million, commenced on August 1, 2021, and was utilized to complete critical regulatory and clinical operational activities, such as protocol finalization, clinical trial site identification, drug packaging, and submission of a new Investigational New Drug Application, or IND, to the U.S. Food and Drug Administration, or FDA, for investigating cytisinicline in nicotine e-cigarette users. In November 2021, we announced that the FDA had completed their review and accepted the IND application to investigate cytisinicline as a cessation treatment in this population. In June 2022, following NIH review of completed milestones, we announced that we were awarded the next grant funding from the NIDA in the amount of approximately $2.5 million, which is expected to be used to conduct the ORCA-V1 Phase 2 clinical trial.

In June 2022, we announced the initiation of the ORCA-V1 Phase 2 clinical trial. ORCA-V1 will evaluate the efficacy and safety of 3 mg cytisinicline dosed three times daily compared to placebo in approximately 150 adult e-cigarette users at five clinical trial locations in the United States. Participants will be randomized to receive cytisinicline or placebo for 12 weeks in combination with standard cessation behavioral support.

The full grant award of $2.8 million is expected to cover approximately half of the total ORCA-V1 clinical study costs. The Primary Investigators for the grant are our Chief Medical Officer, Dr. Cindy Jacobs, and Dr. Nancy Rigotti, Professor of Medicine at Harvard Medical School and Director, Tobacco Research and Treatment Center, Massachusetts General Hospital.

For the six months ended June 30, 2022, we incurred $0.3 million in qualifying R&D expenditures under the NIH grant, which has been recorded as a reduction in R&D expense. As of June 30, 2022, we had $0.3 million in grant receivable related to the NIH grant.
