• Primary endpoint family of objective response rate (ORR) by blinded independent central review using RECIST v1.1 and overall survival (OS);

Fourth Quarter Financial Results
Research and development expenses for the three months ended December 31, 2020 totaled $5.1 million compared to $8.4 million for the same period in 2019. General and administrative expense for the three months ended December 31, 2020 totaled $2.9 million compared to $3.4 million for the same period in 2019. Additionally, during the three months ended December 31, 2020 and 2019, we recorded a $3.2 million and $0.6 million non-cash warrant revaluation loss, respectively, and a $65.4 million and $11.0 million non-cash future tranche right revaluation loss, respectively, related to securities issued in connection with our December 2019 private placement transaction.

As a result of the factors above, net loss applicable to common stockholders for the three months ended December 31, 2020 was $76.7 million, or $2.11 per basic and diluted share, compared to net loss applicable to common stockholders of $51.3 million, or $1.76 per basic and diluted share, for the same period in 2019. Excluding non-cash loss of approximately $68.6 million and $11.6 million for the three months ended December 31, 2020 and 2019, respectively, and deemed dividends of approximately $28.0 million for the three months ended December 31, 2019, all related to the securities issued in connection with the December 2019 private placement transaction, net loss applicable to common stockholders was $8.0 million, or $0.22 per basic and diluted share, and $11.7 million, or $0.40 per basic and diluted share, respectively (calculated based upon the basic weighted-average number of common shares, due to the antidilutive effect of net loss).

Full Year Results
Research and development expenses for the year ended December 31, 2020 totaled $24.8 million compared to $34.9 million for the same period in 2019. General and administrative expenses for the year ended December 31, 2020 totaled $11.9 million compared to $12.5 million for the same period in 2019. Additionally, for the year ended December 31, 2020 and 2019, we recorded a $3.7 million and $72.4 million of non-cash warrant revaluation loss, respectively, and a $0.6 million and $11.0 million non-cash future tranche right revaluation loss, respectively, as well as non-cash deemed dividends of approximately $28.0 million during the year ended December 31, 2019, increasing net loss attributable to common stockholders, as further discussed above under fourth quarter results.

As a result of the factors above, net loss applicable to common stockholders for the year ended December 31, 2020 was $112.7 million or $3.33 per basic and diluted share, compared to net loss applicable to common stockholders of $84.6 million, or $2.96 per basic and diluted share, for the same period in 2019. Excluding non-cash loss of approximately $76.1 million and $11.6 million for the years ended December 31, 2020 and 2019, respectively, and deemed dividends of approximately $28.0 million for the year ended December 31, 2019, all related to the securities issued in connection with the December 2019 private placement transaction, net loss applicable to common stockholders was $36.6 million, or $1.08 per basic and diluted share, and $45.0 million, or $1.57 per basic and diluted share, respectively (calculated based upon the basic weighted-average number of common shares, due to the antidilutive effect of net loss).

As of December 31, 2020, our cash, cash equivalents, and short-term investments totaled $37.7 million. Based on our current operating plan, we anticipate that our current cash, cash equivalents, and short-term investments, will fund our operations through the second quarter of 2022.
