Thank you, Scott. As the financial results for the 3 months and 9 months ended September 30, 2020 were included in the press release that was issued this morning, I'll focus my comments today on a high-level overview for the quarter.
For the 3 months ended September 30, 2020, total net revenue was $15.7 million compared to $2.5 million for the 3 months ended September 30, 2019. Net product revenue for the 3 months ended September 30, 2020 was $5.8 million, with $3.5 million for YUTIQ and $2.3 million for DEXYCU, compared to net product revenue for the 3 months ended September 30, 2019 of $1.0 million generated primarily by DEXYCU. Please note that the net product revenue represents product purchased by EyePoint's distributors, whereas customer demand represents purchases of product by physician practices and ASCs from EyePoint distributors.
Net product revenue from licenses, royalties and collaborations for the 3 months ended September 30, 2020 totaled $9.9 million compared to $1.5 million in the corresponding quarter in 2019. This was driven by payments associated with the expansion of our license agreement with Ocumension for additional markets in Asia.
Operating expenses for the 3 months ended September 30, 2020 were $17.7 million versus $16.6 million in the prior year period. This increase was driven by a $1.6 million increase in cost of sales, a $1.4 million increase in G&A expense and a $0.6 million increase in R&D expense being offset by a $2.5 million reduction in sales and marketing expense. Non-operating expense, net, for the 3 months ended September 30, 2020 totaled $1.8 million of net interest expense. Net loss for the 3 months ended September 30, 2020 was $3.8 million, or $0.03 per share, compared to a net loss of $15.6 million, or $0.15 per share, for the prior year quarter.
Cash and cash equivalents at October 31, 2020, totaled $30.5 million compared to $28.7 million at September 30, 2020 and $22.2 million at December 31, 2019. We expect that our cash on hand and projected cash inflows from anticipated YUTIQ and DEXYCU product sales, licensing and research collaboration transactions, along with additional anticipated financing activities can fund the company's operating plan into 2021. Given our current assumptions for the extent of the COVID-19 related closures in various regions across the U.S., our careful management of cash should enable us to achieve some important catalysts, including the filing of the IND with the FDA for EYP-1901 and the initiation of the Phase I study. We continue to evaluate and pursue non-dilutive sources of capital, including ex-U.S. out-licensing opportunities for our commercial products and delivery technologies.
I now turn the call over to the operator for questions.
