Yes, thanks, Ronnie. First, I'd like to introduce a new member of the finance team, Tony Kalajian, who joins us as Chief Accounting Officer. Tony has consulted for OncoCyte for many years and brings over 20 years of experience in domestic and international financial reporting, auditing and accounting. Welcome, Tony. Now to our results. At June 30, 2019, we had cash, cash equivalents and marketable securities of $36.3 million as compared to $8.4 million at December 31, 2018. Through the second quarter ended June 30, 2019, we incurred a net loss of $5.4 million or $0.10 a share as compared to $4.5 million or $0.12 per share for the 3 months ended June 30, 2018. Our operating expenses for the 3 months ended June 30, 2019, were $5.5 million and $4.3 million on an as-adjusted basis as compared to $4.2 million or $3 million on an as-adjusted basis for the same period in 2018. We have provided a reconciliation between GAAP and non-GAAP operating expenses in the financial tables, including with our earnings release, which we believe is helpful in understanding our ongoing operating expenses. Research and development expenses for the current quarter were $1.5 million as compared to $2.3 million for the same period in 2018, a decrease of about $800,000. This decrease was primarily due to amortization expense of intangible assets reflecting a noncash impairment charge we recorded as of June 30, 2018. These related to intangible assets for therapeutic uses that we no longer plan to develop or commercialize. There was no amortization expense for intangible assets recorded during the current quarter. General and administrative expenses for the second quarter of 2019 were $3.6 million as compared to $1.3 million for the same period in 2018, an increase of $2.3 million. This increase is primarily attributable to investment banking-related expenses, personnel and related expenses, including management transition costs accrued as of June 30, 2019; legal, recruiting, accounting, auditing and tax services expenses; and stock-based compensation expense due to additional equity grants, including new hires. Sales and marketing expenses for the 3 months ended June 30, 2019, were $300,000 as compared to $600,000 for the same period in 2018. As Ronnie mentioned earlier, in late May, we made a key hire in marketing, and we expect that our sales and marketing expenses will increase modestly as we continue to build the sales and marketing team at the appropriate time for our planned commercialization. Cash used in operations was $2.8 million for this quarter as compared to the approximately $4 million during the second quarter of 2018, in line with our expectation for the current quarter's cash burn of around $1 million a month. That concludes my remarks concerning our financial highlights. Operator, we are now ready to open the call for Q&A.
