Thanks, Chuck, and good afternoon again, everyone. At June 30, 2021, we had a cash balance of approximately $25.2 million. Our current cash position sets us up very well for conducting our planned clinical trials and manufacturing of our Hemopurifier for those trials.
During the 3 months ended June 30, 2021, we raised approximately $17.5 million in net proceeds from the issuance of common stock and the combination of a registered direct financing and ATM sales.
We recorded approximately $115,000 of government contract revenue on our Phase II melanoma cancer contract in the 3 months ended June 30, 2021. We also recorded approximately $17,000 of revenue related to our cost-reimbursable sub-award arrangement with the University of Pittsburgh in connection with an NIH contract entitled Depleting Exosomes to Improve Responses to Immune Therapy in Head and Neck Cancer. As a result, we recorded a total government contract revenue of approximately $132,000 in the 3 months ended June 30, 2021. And we did not record any government contract revenue in the 3 months ended June 30, 2020.
Our consolidated operating expenses for the 3 months ended June 30, 2021, were approximately $2.2 million compared to $1.4 million for the 3 months ended June 30, 2020. This increase of approximately $800,000 or 58% in the 2021 period was due to increases in payroll and related expenses of approximately $580,000, general and administrative expenses of approximately $221,000 and professional fees of approximately $19,000.
The $580,000 increase in payroll and related expenses was primarily due to the combination of a $234,000 increase in R&D payroll as a result of hiring additional scientists, a $210,000 bonus payment to our CEO as a result of achieving certain milestones laid out in his employment contract, a $64,000 increase in general and administrative payroll expense as a result of additional headcount and a $36,000 increase in stock-based compensation.
The $221,000 increase in general and administrative expenses was primarily due to a $133,000 increase in our subcontractor expenses related to our government contracts and a $74,000 increase in insurance expenses.
The $19,000 increase in professional fees was primarily due to a $50,000 increase in legal fees, which was partially offset by a $22,000 decrease in scientific consulting expenses and a $6,000 decrease in accounting expenses. Other expense was nominal during the first quarter ended June 30, 2021.
As a result of the changes in revenues and expenses that I just reviewed, our net loss before noncontrolling interests increased to approximately $2.1 million for the 3 months ended June 30, 2021, from approximately $1.4 million for the 3 months ended June 30, 2020.
We included these earnings results and related commentary in a press release issued earlier this afternoon. That release included the balance sheet for June 30, 2021, and the statements of operations for the 3-month periods ended June 30, 2021, and 2020. We will file our quarterly report on Form 10-Q following this call.
Our next earnings call for the second -- fiscal second quarter ending September 30, 2021, will coincide with the filing of our quarterly report on Form 10-Q in late October or early November 2021.
And now Chuck and I would be happy to take any questions that you may have. Operator, please open the call for questions.
