Note 2 - Liquidity and Management’s Plans

As of June 30, 2019, the Company had working capital and stockholders’ equity of $16,339,613 and $13,742,887, respectively. During the six months ended June 30, 2019, the Company incurred a net loss of $5,978,626 and used $5,676,314 in its operating activities. The Company has not generated any revenues, has incurred net losses since inception and does not expect to generate revenues in the near term. Factors such as these and the Company’s projected cash burn raised substantial doubt about its ability to continue as a going concern for at least one year from the issuance of these financial statements. However, management has substantial latitude as to the timing and amount of the expenses it incurs and such latitude and control of those expenditures alleviated the substantial doubt. The Company believes that it has sufficient capital to meet its operating expenses and obligations for the next twelve months from the date of this filing. However, if unanticipated difficulties or circumstances arise, the Company may require additional capital sooner to support its operations. If the Company is unable to raise additional capital whenever necessary, it may be forced to decelerate or curtail its research and development activities and/or other operations until such time as additional capital becomes available. Such limitation of its activities would allow the Company to slow its rate of spending and extend its use of cash until additional capital is raised. There can be no assurance that such a plan would be successful. There is no assurance that additional financing will be available when needed or that the Company will be able to obtain such financing on reasonable terms.
