Thank you, Marvin, and to everyone for joining today. Here are some key financial highlights for the first quarter of 2021. Total revenue for the 3 months ended March 31, 2021, was $1,006,000 a decrease of 2.7% compared to $1,034,000 during the 3 months ended March 31, 2020. CGuard revenue remained essentially unchanged at $970,000, during the 3 months ended March 31, 2021, as compared to $971,000 during the same period last year. In spite of the continued postponement of many elective procedures as a result of the residual COVID redirected resources. However, MGuard Prime EPS revenue decreased by 41.3% from $63,000 during the 3 months ended March 31, 2020 to $37,000 during the 3 months ended March 31, 2021, largely driven by the predominant industry preferences favoring drug-eluting stents rather than the bare metal stents, such as MGuard Prime EPS.
For the 3 months ended March 31, 2021, we had a gross profit of $106,000 compared to a gross profit of $295,000 during the same period last year. This decrease in gross profit resulted from an increase in write-off of $156,000, which were driven mainly by a component supply issue and an increase of $33,000 in miscellaneous expenses. Gross margin decreased to 10.5% during the 3 months ended March 31, 2021, compared to 28.5% during the 3 months ended March 31, 2020, driven by the factors just mentioned. Total operating expenses for the quarter ended March 31, 2021, were $3.4 million, an increase of 47.7% compared to $2.3 million for the same period in 2020. This increase was primarily due to an increase of $430,000 in salary expenses and related accrual expenses mainly driven by additional resources in our product development and sales infrastructure.
$248,000 in share-based compensation-related expenses due to the expense recognition of grants made in the second half of 2020, $136,000 in development expenses associated with CGuard EPS, mainly related to the new advanced delivery system and accessories, $118,000 of directors and officers liability insurance expense due to increased premiums caused by recent trends in the overall insurance industry, an increase of $108,000 in shareholder related expenses due to the special shareholder meeting and $64,000 in miscellaneous expense.
For the 3 months ended March 31, 2021, financial income increased by 65.1% to $71,000 from $43,000 during the same period last year. The increase of financial income primarily resulted from exchange -- changes in exchange rates. Net loss for the first quarter of 2021 totaled $3.2 million or $0.53 per basic and diluted share compared to a net loss of $2 million or $6.42 per basic and diluted share for the same period in 2020. The average amount of shares outstanding used for the earnings per share calculation were 6.1 million in Q1 2021 and 300,000 in Q1 2020, with both numbers having been adjusted for the reverse split.
As of March 31, 2021, cash and cash equivalents were $44 million compared to $12.6 million as of December 31, 2020. During the first quarter of 2021, as Marvin mentioned, the company raised $35.1 million net through various equity transactions.
With that, I'd like to turn the call over for questions. Operator, please go ahead.
