Cash And Cash Equivalents [Abstract]
Liquidity	Note 2. Liquidity The Company had a net loss of $13.2 million during the six months ended June 30, 2020 and has an accumulated deficit of $171.0 million at June 30, 2020 resulting from having incurred losses since its inception. The Company had $62.5 million of cash on hand at June 30, 2020 and used $12.2 million of cash in its operating activities during the six months ended June 30, 2020. The Company has financed its operations principally through issuances of equity securities. On June 26, the Company sold 34,848,484 shares of common stock in an underwritten public offering at a price of $1.65 per share for net proceeds of $53.7 million. The Company expects to continue incurring losses for the foreseeable future. However, the Company expects that its current cash and cash equivalents balance are sufficient to enable the Company to meet its obligations for at least the next twelve months from the date of this filing.

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
