Fourth Quarter and Full Year 2021 Financial Results

Cash used in operations for the three-months ended March 31, 2022, and 2021 was $4.2 million.

We ended the first quarter 2022 with a cash balance of $34.7 million as compared to $38.9 million at December 31, 2021.

Net loss for the quarter ended March 31, 2022, was $7.8 million which includes non-cash expenses of $813,000 compared to a net loss for the same period of 2021 of $3.8 million, which includes non-cash expenses of $358,000. Per share losses were $0.23 in the first quarter of 2022 as compared to $0.16 per share, for the same period in 2021. This increased net loss reflects our increased clinical and pre-clinical activity and increased headcount.
